Seal

Description:

The invention relates to devices for preventing unauthorized access to objects, for example, to sealing devices. and it can be used for sealing various goods, shipping counters, containers, wagons, as well as various special packages, equipped with sealing knots.

In the last years, the constructive solutions of the cable sealing devices are used on a large scale, which fulfill the protective function by locking the parts of the seal with the help of the hooks.

An indicator seal is known for metrological devices, which confines a body with a cylindrical cavity with longitudinal ribs, executed on its inner surface, and holes, executed in the same plane on the cylindrical surface for a flexible sealing element. The wedge also confines a core with holes, coaxial with the holes on the lateral surface of the body, a ratchet mechanism, executed with the possibility of eontia ^ l ^ cii with longitudinal ribs of the eilindriae cavity, and a detachable handle on the front surface of the body. outer end porphyry. At the same time, the core is located the eilindrial cavity of the body with the possibility of rotating in a certain direction. For attachment and functional use the seal is equipped with a safety device, located inside! a rectangular cavity and equipped with rigid elements, which contact the inner nerves of the cavity, and which confine о the protrusion, which enters a groove between the eilmdrial and rectangular cavity of the body. Moreover, the protrusion of the safety device, which enters the groove between the cavities of the body, is equipped with a flexible tongue, which enters a ring groove between the annular edges of the core. At the same time, the portion of the core between the annular edges is executed in the form of a cross, with the prominent portions of which contact the flexible tongue [1].

However, the flexible tongue engraving the cross cannot serve as a safe stop to prevent the rotation of the seal core m the already assembled construction, and the constructive solution of the safety device with rigid elements on its front ends does not exclude the possibility of its sealing and replacement. Subsequent seals for unauthorized access to the protection object. Moreover, the procedure for assembling this aeon requires the exact technological adjustment of the longitudinal dimensions of all the multiple parts of the seal. As a result, the indicator sill described is not a sufficient device for safe operation and complicated manufacturing.

The closest solution to the device claimed after the technical sphere is a seal, which confines a body in the form of a beaker and a core, located coaxially m, which perpendicular to their axis are executed coaxial holes for a flexible sealing element. The core is provided with a ratchet mechanism with two levers of the ratchet with identical ratchet, which interacts with the possibility of rotating in a direction with the longitudinal clouds of the ratchet mechanism, executed on the inner surface of the body. . A separating disk is located between the core chambers and the detachable plate is attached to the outer end of the core. In the body from the open end porphyry is performed о the anterior annular groove. In this seal for preventing access !! unauthorized to the sealed object is performed disk locking !! the outer end portion of the core, located on the annular groove of the body, with the help of a safety ring [2].

The disadvantage of this! device is the reduced flabilitata, conditioned by the free access to the biocare it with the possibility of losing it, in connection with the fact that the access to the separation line between the core and the body is free and the lead can be opened unobserved by the resealment.

The technical problem, when solving the proposed invention, is to improve the construction of the seal in order to increase its seal at its unsanctioned opening, as well as to improve its manufacturing process. .

The seal, according to the invention, removes the disadvantages mentioned above by confining a glass-shaped body and a core, located coaxially, which perpendicular to their axis are executed through the coaxial pierced holes for an element of flexible core. it is equipped with a ratchet mechanism with two levers of the same ratchet, which mediates the potential of the roll in a diaphragm with the longitudinal ribs of the ratchet mechanism, executed on the surface of the interior of the body. The wedge also confines a disc of separation of the core, located between its orifice pierced, о inner ring groove, executed in the body from the slit end portion, and о plate

MD 861 Ζ 2015.07.31 detachable, fixed on the outer end of the core. The longitudinal nerves of the ratchet mechanism are located at the inner end portion of the body. The ratchet wheel brackets are located on the inner end portion of the core. Three spatially separated disks are located on the outer end portion of the core. The superficial surface of the first and of the hill the second disc, in front of the perforated holes, is endowed with, at least, a guide groove, executed on a helical line between the lateral surfaces of the discs. The guide groove of the first disc is executed with the open ends, and the guide groove of the second disc is executed with the open end from the first disc and the opposite end - blind. At the edge of the groove on the inner cylindrical surface of the body is located, the pufin, о prominence with the possibility of entering and moving in the guide grooves of the first and second disc. The detachable plate on the side edges is provided with the detachable blades, executed with the possibility of supporting it in the front end of the body wall from the open end portion. The third disc is executed opposite the annular candlestick of the body to form a tight joint.

At the same time, the cross-section of the guide canoes has the same shape and dimensions and is connected to the cross-section of the projection.

The guide grooves of the first and second disc are executed at an angle of 10 ° ... 75 ° in front of the axis of projection of the disc on the front surface, and the candum length of the second disc is multiple of the number of steps. of the ratchet levers on the ribs of the ratchet mechanism to the end of the projection at the blind end.

In addition, the distance between the first and second discs is established, which ensures the possibility of free rotation of the projection.

The result, obtained with the help of the claimed invention, consists in increasing the protective properties of the sealing device.

This result is achieved on account of a double biocharging mechanism to prevent the rotation of the seal core in the assembled state, one of which in the same dimf! of rotation is ensured by a ratchet mechanism, and the other - by blocking the rotation in the opposite direction, due to the creation of a pair: protrusion from the body - the blind guide groove of the second disc.

Indeed, the execution on the front surface of the first disc between its lateral surfaces of a guide groove on the dicoidal line creates the possibility of penetrating the body prominence !! in the gap between the first and the second disc and the realization of the trial !! for wrapping the core of a flexible sealing element, passed through the coaxial pierced holes. At the same time, the measurement process takes place in the same direction because the rotation of the core in reverse gear is blocked, in particular, by the ratchet levers of the ratchet mechanism.

At the further advance of the core! and therefore, when moving the projection into the guide groove on the front surface of the second disc, the projection is fixed in the account! support!! in the blind end of the candlestick.

As a result, the possibility of any displacement of the core both translafia and rotafia is safely blocked. At the same time, access to the biocharging elements in the assembled seal is completely excluded, which makes the construction of the seal absolutely resistant to opening.

Execution of the guide candles of the first one and the one! the second disk at an angle of

10^a... 75 ° in front of the projection axis of the disc on its front surface is conditioned by the fact that at angles smaller than 10 ° the reliability of the pair contact decreases: the protrusion of the body - the blind guide groove needle !! the second disc, and at angles greater than 75 ° there are technological difficulties in the execution of the reed, taking into account the actual width of the front surface of the disc and the approximation of this groove to the lateral surface of the disc.

The range of angles indicated has been empirically confirmed.

The order of multiplicity of the length of the guide disc of the second disc in the number of steps of the ratchet lever levers on the ribs of the ratchet mechanism until the end of the projection at its blind end guarantees the safe engagement of the ratchet lever levers of the core with the longitudinal ribs. of the mechanism! with ratchet, executed on the inner cylindrical surface of the body.

As a result, only the complete destruction of the seal, obviously primitive, can have access to the sealed object.

The proposed construction of the seal is technological, possesses improved operating characteristics, can be executed with standard equipment and under the present conditions is universal for use in various fields of human activity.

The invention is explained by the drawings in fig. 1-8, which represents:

FIG. 1, the cross section of the seal body;

FIG. 2, side view of the seal body;

FIG. 3, the cross-section of the core;

FIG. 4, the cross section of the seal as a whole;

FIG. 5, section AA of the seal (see fig. 4);

FIG. 6, the cross section of the seal in the transport position;

FIG. 7, the cross-section of the seal in the sealing process;

FIG. 8, the cross section of the seal in the process of opening the seal.

The seal confines a cup-shaped body 1 (Figs. 1, 2) with a cylindrical cavity 2, on the inner end portion with longitudinal 3-sided longitudinal ribs of the ratchet mechanism. In the lateral surface of the cylindrical portion of the body 1 are executed to the pierced hole 4 for introducing a flexible sealing element. On the inner surface of the cavity and the eilindries 2 from the open end porphyry are executed о ring groove 5 (fig. 1), at the inner edge of which is located о protrusion 6. From the outer part of the body 1, at the open end porphyry a handle 7 is executed (fig. 1, 2), the width of which is equal to the outer diameter of of the body 1, and on its surface is applied the information necessary to identify the seal.

The core of the seal 8 (fig. 3) has the bore holes 9, coaxial with the bore holes 4 of the body 1, the levers of the ratchet cloth 10, executed on the inner end portion with the possibility of being inserted into the inner end portion of the body 1 (fig. 3). and 5), a separation disc 11 between the perforated holes 9. On the outer end portion of the core 8 are placed three discs! spatially separated 12, 13, 14, respectively. On the front surface of the disc 12 it is executed on a droid line ^ between the lateral surfaces of its guide groove 15 with the open ends. On the front surface of the disc 13 it is executed on a helical line between the lateral surfaces of its guide groove 16 with the open end of the disc side 12 and the opposite end - blind. The distance between the discs 12 and 13 is such that it allows the projection 6 to rotate freely in the cavity formed between these discs (fig. 6 and 7). On the disc 14 of the outer end portion of the core 8 is fixed a rectangular detachable plate 17 with the detachable blades 18, which at the assembly of the seal rests on the end ^^ i ^] ^ i ^ lui 1 (Figs. 6, 7). The plate 17 is fixed with the possibility of detachment from the core 8 on its fine porphyry, the tephima which corresponds to the inner diameter of the body.

When pre-drilling the parts of the seal for assembly on the handle surface, the information required for the seal is applied. At the same time, if necessary, specific identification data can be applied on the outer surface of the disk 14.

In the process of the asram-bi ^^ i ^^ i of the described seal (fig. 6) the core 8 is inserted inside the ^^ i ^^^ i ^ lui 1 through the cavity 2, effecting translafia and rotational movements so that the protrusion 6 being able to enter the guide candle 15 of discs 12 and, moving through the groove, to pass into the cavity between discs 12 and 13. At the same time, he he detachable 18 of the payment 17 are spryim! at the end of the body 1 and the ratchet levers 10 engage with the longitudinal ribs 3 of the ratchet mechanism.

The given assembly of the component parts of the seal corresponds to its transport position and is non-removable.

In this position the seal is ready for use, at the same time the rotation of the core 8 is only possible in the direction corresponding to the process of tightening on it a flexible sealing clementum 19 (Figs. 4, 7, 8). The rotation of the core 8 in the opposite direction is blocked by the ratchet lever levers 10, and attempts to remove the core 8 from the body 1 are prevented by the presence of the projection 6 in the cavity between the discs 12 and 13.

In the sealing process (fig. 7) of the object one end of the sealing element 19 is inserted through the pair of coaxial bore holes 4 and 9 of the body 1 and the core 8, respectively, inside the seal and, performing several rotational swings. of the plate 17, the sealing elemental 19 is wound on the core 8.

The other end of the sealing element 19 is passed through the respective devices of the protected object and is introduced by another pair of coaxial through holes 4 and 9, separated by the first pair by the separation disc 11, inside the seal, where it is mf Worn in a similar way on core 8 (fig. 7).

MD 861 Ζ 2015.07.31

After winding the required number of turns of the sealing member 19, the blades 18 are detached from the plate 17 and, by making a rotational motion of the plate 17, bring the projection 6 to the open end of the guide groove 16 of the disc 13. Then it advances the projection 6 through the groove 16 to its back in the blind end, thus fixing rigid and inaccessible to the external action! its position in caneku! (Fig. 8). At the same time, the ratchet wheel levers 10 of the core 8 reach the bottom of the body 1 and support themselves! in the protrusions of the longitudinal nerves 3, forming a ncdcimo ^ ttO ^ iicl construct.

Plate 17 is separate! from midday.

As a result, the proposed seal is removed! any possibility of changing the position of the core both by rotating it and by moving horizontally!

Unlock the given seal is done! by cutting the sealing element.

The body of the seal and the core are made of malt plastic! resistant, at the same time! the body is made of a transparent material, which allows to visually evaluate the integrity of the seal.

As a sealing element, for example, a metal cable, a polymer fiber cable or any other device suitable for this purpose is used.

It should be noted that the invention claimed! the detailed description of the technical solution refers! the о variant! for use in the construction of the seal of a protrusion and how much о crneku! guide on the front surface! of the two! core discs.

However, the claimed version! of the invention, which confines the admission "the little one", referring to the number of projections on the cylindrical surface! interior! body and guide grooves on the front surface of the discs, suggest c! the elements indicated may be more.

If two are used in the construction of the seal! proeminenfe. and two and two are provided on the first and second discs! guide grooves, executed on the front surface of the disks on a helical line! between the lateral surfaces of the discs, then it is optimal to distribute the projections on the circumference at the edge of the candum at 180 ° and to execute the cmdnnlor in each disc in the opposite direction.

Yes it is! In the construction of the seal a few projections are used, then in the first and the second disc some guide channels can be provided, which tree parallel to о muni distances one from the one ^ Ra, executed on the ehcoidal file! between the lateral surfaces of the discs, and a few projections at the fifth edge of the inner cylindrical surface! of the body, each prOemmed! in! in the corresponding groove of the first and second discs with the possibility to move ^ TH in it.
