Power seal

The invention relates to locking devices for special purposes, especially seals, and can be used to lock the doors of all types of containers, passenger cars and autofurgers, other means of transporting goods, as well as warehouses and other objects.

The main direction of the elaboration of the design of the seal seals is associated with an increased degree of protection created by them, determined by the improvement of the subassembly for fixing the contactor's portion, for example, the rope or the cable, by strengthening its interaction with the biocharging means.

The way to solve this problem is to create a fastening subassembly with the use of a steep-edge biocharger, which creates in the chosen direction or the forced shear action, which partially deforms and endangers the cable integrity.

A monobloc seal with a twist is known, which confines a body with a hole pierced with one end of the cable attached to it, a channel for passing the free end of the cable and, located at an angle opposite it, a hole threaded into the wall of the body. , which passes into a hole with a larger diameter for placing the screwdriver in them. The spindle is executed in the form of a detachable handle, a biocharging head with threaded, cylindrical or conical ends, о groove with weakened section between the last edges. Moreover, the axis of the holes for fixing the end of the cable and for the passage of its free end are perpendicular to the axis of the hole for the location of the twist. At the same time, the channel for passing the free end of the cable and the hole with the fixed end of the cable are cross-linked, and all the points of their axial lines belong to the different parallel planes [1].

A disadvantage of this construction is the technological process of quite complicated production, which includes when making the seal the rotary operation of the semi-fabricated for the execution of the cross channels for the placement of the cable segments.

Moreover, the presence in the biocharging head of the groove with weakened section between the cylindrical and conical portions reduces the resistance of this part, because the shear action, produced by sealing, can lead to its destruction due to the rigid interaction with the cable. As a result, the reliability of the construction described is reduced.

At the same time, the presence in the twist of the detachable handle not only increases the workload of the process of making the seal, but also unnecessarily increases the volume of embedded metals of the product.

As the closest solution is presented a biocare device, which confines a body with a smooth channel with the possibility of fixing in it the passive end of the cable, a passage channel with the possibility of pulling through it the working end of the cable with the formation a minimum size loop and a support channel, which intersects the passage channel, with a biocharging element located therein. The diameter of the passage channel is smaller than the diameter of the support channel in their intersection region. The biocare element is executed in the form of support portions and at the same time, with the possibility of passing it in the interaction zone with the cable segment in the passage channel under the shear action, exerted on the straight line. The front porphyry of the biocharging element has a tapered shape with a tip and is executed with one-sided tufts. At the same time, the biocharging element in the support channel is fastened either with a slight tightening or by means of an adhesive tape [2].

The device described does not possess о Ability large enough. This is due to the fact that in the patented construction the fixing of the biocharging element in the support channel prior to sealing is carried out either with a slight tightening or by means of an adhesive tape. With о such attachment and presence of the support portion of the biocharging element that extends partially outwards, it is not difficult to extract the biocharging element from the channel, to separate by performing simple actions the hidden portion and to reintroduce the remaining portion. of the biocharging element in the support channel. As a result, the device's protection against unauthorized penetration will be completely eliminated.

Moreover, the need to apply the biocharging element to seal the extreme load by using tools with a shear mechanism, such as

MD 910 Ζ 2015.12.31 would be of electric or hydraulic type, means о extreme load on the locking element. As a result of the interaction under this load of the sharp portion of the biocharging element with the metal wires of the cable, its breakage is not excluded, which significantly reduces the reliability of the device.

The problem solved by the invention consists in improving the operating conditions of the seal, in particular, the reliability, the degree of protection and comfort in use, as well as in simplifying the process of making it.

The problem is solved by the fact that the force seal confines a body with a support channel executed along the longitudinal axis of the body, two pierced channels executed perpendicular to the longitudinal axis of the body - a smooth channel for rigid fixing of the passive end of a cable and the second passage channel for pulling through it the working end of the cable with the formation of a loop of minimum dimensions. In the support channel is located a biochar element, which intersects the passage channel. The biocharging element confines a support portion and a toothed one, with the possibility of its movement in the support channel and the interaction with the cable portion of the passage channel under the action of a force exerted on the longitudinal axis of the body. The diameter of the passage channel is smaller than the diameter of the support channel in the region of their intersection. The support channel is pierced, at the end of the body at least two portions of the support channel are executed with different diameters, their axes being parallel and displaced from one another. The smaller diameter portion is executed with internal thread, being located at the end of the body from the passage channel. The biocare element is located between the smaller diameter portion of the support channel and the passage channel, and from the smaller diameter portion the biocon element is supported in the longitudinal direction along the projection, formed at the junction of the support channel portions.

The extreme load on the biocharging element can be achieved by screwing the detachable handle into the threaded portion of the support channel.

The biocharging element in the support channel can be sealed with a silicone sealant.

The toothed portion of the biocharging element can be executed in the form of a cylinder with a cone-shaped end.

The cone angle of the toothed portion may be 15 .. .30 °.

The technical result consists in improving the protective properties of the seal of force, determined by the reliability of the construction, as well as in simplifying the manufacture of the product in general and its component parts and its subsequent use.

In order to obtain the technical result indicated in the construction of the seal, there is provided a pierced channel, which intersects the channels for the placement of the cable segments and which consists of two portions. At the execution of the portions of the support channel of different diameters, with parallel axes displaced one against the other, a prominence is formed instead of their junction. The biochar element inserted in the support channel from the smooth channel is supported in the given projection and is fixed on it. As a result, when the cable is inserted into the smooth channel, the possibility of action on the biocharging element is excluded in order to retract it in the transport position.

Execution of the toothed biocharging element with a cone-shaped end allows the cable to be refined securely due to the fact that in the sealing process when exerting pressure on the biocharging element, the cone passes through the cable and attaches to it, which ensures reliable interconnection and excludes the possibility of unauthorized removal of the working end of the cable.

Execution of the cone angle of the toothed portion within the limits 15 ... 30 ° is a necessary and sufficient condition for the given construction. This is due to the fact that at angles less than 15 ° the length of the biocharging element is increased, therefore, also the dimensions of the seal, and at angles greater than 30 ° the value required for the deformation of the force action, exerted by man, increases significantly. on the biocharging element by screwing into the threaded portion of the biocharging channel of a portable handle.

The sealing force is reliable, it excludes the possibility of access to the locking element, therefore, the possibility of resealing it and offers virtually 100% safety in the protection of objects.

The proposed construction is technological, because it is simple for the execution of all component parts and can be made using standard equipment.

The presence of the removable portable handle for the action on the locking element of the seal significantly reduces the volume of embedded materials and the costs for its production.

The invention is explained by the drawings in FIG. 1-7, which represents:

FIG. 1, the cross-section of the assembled seal;

FIG. 2, the locking element in isometry;

FIG. 3, 4, 5, cross section of the seal at different stages of the assembly process;

FIG. 6, 7, cross section of the seal in the process of screwing and removing the removable handle, respectively.

The force seal confines a body 1 (figs. 13 - 5) with a smooth channel 2 for the rigid attachment of the passive end 3 of the cable 4, a passage channel 5 for pulling through it the working end 6 of the cable 4 and a channel support 7 executed along the longitudinal axis of the body 1. At the end of body 1 at least two portions 8, 9 of the support channel 7 are executed with different diameters, the axes of which are parallel and displaced one by another. The portion 9 of the support channel 7 is executed with internal thread. Channels 2 and 5 are parallel to each other, and the portion 8 of the support channel 7 is perpendicular thereto, at the same time their axial lines are in one plane. In the support channel 7, inside the portion 8 is located the locking element 10, which passes through the working end 6 of the cable 4 and is fixed therein (fig. 1). In the support channel 7 instead of the joining of the portions 8 and 9 due to the displacement of their axes, the projection 11 is formed.

The locking element 10 (fig. 2) is executed in the form of a device, which confines о supporting portion 12 and о front portion 13, which is executed in the form of a cylinder with a cone-shaped end 14.

For exerting the pressure on the locking element 10, a handle 15 with thread (figs. 6, 7) is provided, inserted in the threaded portion 9 of the support channel 7, with its subsequent removal.

The shear seal body and locking element are made of stainless steel.

The process of assembling the seal (fig. 3) begins with the insertion of the locking element 10 in the portion 8 of the support channel 7 of the body 1 from the smooth channel 2. The advancements of the locking element 11 in the interior of the plate 8 is ejected until the stop 1. his in the prominence 11. At the same time, the connection between the length of the block element 10 and the diaphragm from the projection 11 to the passage channel 5 are selected so that the cable passes freely through the given channel without contacting the lock element 10. The last one, located in the support channel 7, is sealed with the help of a slliaonla hermetic.

Next, in the channel nsted 2, insert the end p ^ iv 3 of the cable 4 (fig. 4) and loosen by any convenient way in each specific case, for example by the pressure loading of the end or the use of a spindle, or by the eeeoemaren plastic of the smooth channel 2 and the body of the seal from it.

This ^ amblm of the component parts of the seal is irreplaceable and corresponds to its transport pattern. The seal is ready for use.

In the sealing port (fig. 5) of the object, the working end 6 of the cable 4 is passed through the block subassembly of the object (in the figure not shown) and inserted into the passage channel 5 of the seal.

At the upright sealing stage (fig. 6) in the threaded portion 9 of the sprymal groove 7 a detachable handle 15 is inserted and at the rotafin in the handle of the handle, due to the fact that the front end of the handle 15 acts on the front end of the support bolt. 12 of the locking element 10, advances the locking element 10 in the direction of the erscsee channel 5 and the working groove 6 of the cable. Reaching the cable, a block elemental 10 with the cone-shaped end 14 pierces it, takes away the slips and exits the cable boundaries in the sprym channel 7. With the open side of the base of the cone 14 it is

MD 910 Ζ 2015.12.31 supports on the cable, and the toothed portion 13 of the locking element 10 is located in the biocharging zone, formed by the separated cable and the adjacent portions of channels 5 and 7. At the same time, the convexity formed on the cable is located in the channel support 7, because its diameter is larger than the diameter of the passage channel 5.

At the end of the sealing process by advancing the biocharging element 10 inside the seal on a length equal to the length of the threaded portion of the handle 15, the handle is removed from the body 1 of the seal, bending it in the left direction (fig. 7).

The sealing process is completed.

Removing or opening the seal during non-hole access is possible only by cutting the loop cable with the help of a special tool with high destructive force, such as pliers, wire clamps or cable clamps.

The dimension of the biocare element corresponds to the distance between the projection and the passage channel and constitutes 16 mm, its cone length is equal to 5 mm, and the cone angle is 22 °. In the support channel the biocharging element was sealed with the aid of the "INDUSTRIES PLENDOR" silicone emitter ^ n ^ lm.

The seal body and the biocharging element are made of steel with the mark 45.

The seal was fixed to the biocare loops of the freight wagon manually with the help of the handle, made of steel with the mark 45, having the length of the thread with a thread equal to 20 mm. As a cable a GOST 766880 steel wire cable with a diameter of 5 mm was used. During the testing process, the seal was subjected to о action in extreme force with the breaking load of 1770 N / mm².

The tests showed that the use of the force seal with the claimed construction excludes unauthorized access to the protected object.
