Power shut-off and sealing device

The invention refers! to means of closing by sealing the material objects in order to prevent unauthorized access to them, in particular, of wagons, refrigerators, cistems, containers for railway transport and other means of transport.

It is known a closing-sealing device, executed in form! of monobloc seal that confines a metal body, in which a clogged hole is executed, in which a head end of a cable is rigidly fixed, a bored hole for the location of the cable closing segment, at the same time! the holes pierced and clogged are parallel to one another! on the other, as well as a cable fastener executed in the form! two! bow balls and placed in the inner cavity! of the body [1].

The disadvantages of the known device consist in the mechanical resistance! and reduced reliability in case of unauthorized opening, because the interaction of the fastener with the free end of the cable in the closed state! it takes place in one plan. Thus, between the rigidly fixed head of the cable and its free head in the closed state! they are forming! eye catching the cable, and when applying a stretching effort it is possible! both the sliding and turning of the cable in relation to the arc balls, as well as the axial displacement! of the head fixed rigidly. This can become the cause of unauthorized opening of the device after! which he may be subject to repeated closure, lighthouse! to be possible! detection of the intentional unauthorized opening.

The problem I solve! invention const! in ensuring the high reliability of the device in combination with the simplicity of the construction.

The problem is solved! by that c! the power-closing device! it confines a metal body, in which a clogged orifice is executed, in which the first end of a cable is rigidly fixed, and a hole provided for the placement of the second end of the cable, and a mechanism for fixing the cable, placed in an executed cavity! in the body. The clogged and stroked holes are executed in parallel body one faf! by the other. The cable fixing mechanism confines the washer! with three petals and о carcass! separation, arched! with a spring, between which are placed three balls with the possibility of their interaction with the second end of the cable at closing. The bottom part! has caviar! be executed! slightly convergent!

The balls can be made of the same diameter and placed radially at an angle of 120 ° perpendicular to the second end of the cable.

The first end of the cable can be fixed rigidly to the clogged hole by means of a deforming fixing sleeve.

The outer part! of the body can be covered! with a protective coating on the table! plastic!.

Position the balls between the three-petal washer and the arched separation housing! with the bow menfine the balls in the plane perpendicular to the second end of the cable and also distributes the voltage exerted evenly! spring to all three contact points of the balls with the cable.

The lower part of the body cavity, in which the cable fixing mechanism, which is slightly convergent, is located, allows to increase the section through which the cable passes and the pressure exerted by the balls in case of unsanctioned opening of the device.

The construction of the cable fixing mechanism ensures! о fastening efficiently! of the cable, because when trying to open the unauthorized opening the fixed cable rotates together! with the balls, preventing both rotation or unscrewing and axial movement! of the cable in relation to the balls.

Thus, the body of the device for closing-sealing the scissor! proposed is made entirely of metal, and the presence of the casing from the table! plastic! prevent! access to its elements in the closed state! for the purpose of unauthorized opening.

The invention is explained! through the drawings in fig. 1-2, which represent !:

FIG. 1, the closing-sealing device, general view!

FIG. 2, the section AA of fig. 1.

The device for closing and sealing the scissor! according to the invention it confines a body 1, formed entirely by the stamping of a sheet of metal, in which a clogged hole 4 is executed, in which the first head 2 of the cable is rigidly fastened by means of the deforming fastening sleeve 3 in place 4. In the opposite side! of the body 1 parallel to the sleeve 3 a perforated hole 7 is executed, through which the second end 5 of the cable is passed for fixing it. The fixing mechanism located in the cavity 8 of the body confines three balls 10, which interact! with the second end of the cable 5 closed, positioned between the washers! 9 with three petals and separation housing 11, arched! with a bow 12.

Position the balls 10 between the washer 9 with three petals and the separation housing 11 arched! with a spring 12 the balls 10 in the plane perpendicular to the second head 5 of the cable and also

MD 552 Z5 2017.08.31 evenly distributes the voltage exerted by the arc to all three contact points of the 10 balls with the cable.

The lower part of the cavity 8 of the body 1, in which the mechanism for fixing the cable, which is slightly convergent!

The balls 10 that secure the cable under the action of the spring 12 are executed from it strong, of the same diameter and placed radially at an angle of 120 ° in plane perpendicular to the second end of the cable 5 at closing. The first end 2 of the cable is fixed rigidly by means of the deformation mounting sleeve 3 instead of its location in the clogged hole 4.

The entrance 6 in the bore 7 is executed with a minimum gap in relation to the second end 5 of the cable. For closing the body of the device, it is provided with a block 14, with which the rolling assembly of the device is obtained by rolling. The rigid construction of the device is covered with a protective coating 15 against the mechanical, thermal and flammable impact, made of plastic mass.

On the outer edges 16, 17 of the body 1 the necessary information is applied.

The construction of the closure-sealing device ensures an efficient fixing of the cable, because when searching for unauthorized opening, the second end 5 of the cable rotates together with the balls 10, preventing both the rotation or unscrewing and the axial displacement of the cable in relation to the balls 10.

The body of the closing-sealing device is made entirely of metal, and the execution of the plastic casing 15 prevents access to its elements in the closed state at the unauthorized opening, in particular, by the freezing method, allows to implant electronic faces, protecting them safe from physical impact, it makes it more comfortable in operation and allows to apply on the outer edges 16, 17 of the body 1 the necessary sealed information.

The shear closure-sealing device is used as follows.

After applying on the outer edges 16, 17 of the body 1 of the necessary sealed information, at the sealing the second end 5 of the cable passes through the slots of the sealed object. Then by entering 6 into the bore hole 7 in the cavity 8, the interaction of the balls 10 with the second end 5 of the cable takes place, compressing the arc 12 and moving radially, thus ensuring the free advancement of the second end 5 towards the exit 13 of the bore hole 7 up to when tightening the catching eye around the seals of the sealed object.

When attempting the unauthorized extraction of the cable from the bore 7 of the body 1 of the device, the balls 10 interact simultaneously with the second end 5 of the cable, preventing its extraction.

The use of the three-ball spring clamping mechanism in combination with the plastic casing made it possible to create a high mechanical resistance shear-sealing device, which withstands loads up to 18 kN, and increased resistance to unauthorized opening.
