Description

FIELD OF THE INVENTION

This invention relates generally to hardware and, in particular, to disposable locking and sealing devices and is intended for locking and simultaneously sealing covered wagons, hopper wagons, tank wagons, refrigerators, covered wagons for cars, doors of cargo containers, vans , warehouses, warehouses, shops, stalls and other facilities, providing control and protection against penetration and unauthorized access to the goods contained in them, having openings in the lock filling nodes hole diameter of at least 6 mm.

More specifically, the invention relates to locking and sealing devices in which a flexible element, for example, a piece of rope (cable), is used as a contactor. In this case, the latter can be performed with the tip of the free end of the rope segment fixed in a self-contained hole in the housing of the ZPU with the formation of an inoperative back loop in the closed state of the device.

State of the art

A flexible locking and sealing device is known having a means of controlling an unauthorized opening, described in patent RU No. 103558 (EV 05/39). It is made in the form of a tab washer mounted in the side of the housing in a two-stage hole and interacting with the surface of the annular groove made on the tip when it is pushed through the hole when an inoperative back loop is formed.

ZPU is also known with a tamper-evident control device described in patent RU No. 2340695 (Е05В 39/02), which also uses a tip attached to the free end of a piece of rope, and on which a neck is made that interacts when pushing the tip in the closed state of the device with spring clip mounted inside the bottom cover.

The disadvantages of patent No. 103558 include the need to manufacture a new metal casing for placing a tab washer in its side. And the disadvantages of patent No. 2396405 are the presence of a metal-consuming, voluminous and difficult to manufacture cover. These patents are for information only.

The proposed result is the achievement of positive results on fixing the free end of the rope of an already closed ZPU when using caps with hooks that are simple in design and in manufacture, which allows minimizing changes in the design of the device described in our application No. 2012145944, according to which the decision to grant a patent dated 26.09 .13 g. (Patent No. 2506391).

In the present invention, the fixation of the tip is associated with the fastening of the end of the rope segment and the lower cover described in this application, namely, the passive end of the rope is installed in the housing by means of a sleeve previously pressed onto it with a free lower part of the hole and placed in a cylindrical cavity of the housing made perpendicular to the upper and the lower sides of the housing, and the upper and lower covers, having a special shape, repeating the shape of the nests in the housing, are mounted in it with a press fitting. Given these circumstances, we have selected our application No. 2012145944 of 09/26/13 as a prototype.

The implementation of the invention

A flexible locking and sealing device comprising a housing 1 closed by upper 2 and lower 3 covers, respectively, with input 4 and output 5 holes in them, and a piece of rope 6, one end of which is passive 7 and the other end is free 8, equipped with a tip 9, passes through the inlet 4 and outlet 5 holes in the lids 2,3, and the through longitudinal channel 10 located between them, with the formation of the loop 11 and fixed in it when closed by the mechanism of non-permanent fixation 12 of the rope segment 6, placed in the blind cavity 13 of the body CA 1, communicating with the longitudinal channel 10, while the passive end 7 is installed in the housing 1 by means of a sleeve 14 previously pressed on it, placed in a cylindrical cavity 15, made perpendicular to the covers 2,3, and having the possibility of displacement relative to its axis, characterized in that that is equipped with an unauthorized opening control device made in the form of an additional fixation mechanism 16 of the tip 9 in the closed state of the device, including a fixing spring 17 and a cap 18 with hooks 19, fixed about on the tip 9, interacting with the fixing spring 17 after pushing the tip 9 through the stepped hole 20 after the formation of the inactive non-working loop 21, made in the bottom cover 3 coaxially of the cylindrical cavity 15, in which the passive end 7 of the rope segment 6 is mounted by means of the sleeve 14 pressed on it moreover, the fixing spring 17 is located in the cavity of the additional fixing mechanism 16, consisting of a stepped cylindrical inlet 20 in the lower cover 3 and the lower part of the cylindrical opening 22 in the sleeve 14, compressing the passive end 7 of the rope 6, the axis of which is located on the axis of the cylindrical cavity 15 of fastening the passive end 7 of the rope segment 6, while the inner diameter of the fixing spring 17 is made smaller than the outer diameter of the hooks 19 of the cap 18 on the free end 8 of the rope segment 6.

The cap 18 with hooks 19 (at least one) is mounted on the tip 9, for example by laser welding.

The passive end 7 of the rope 6 is compressed by an additional locking sleeve 23 with an identifying inscription 24 directly above the top cover 2.

On the housing 1 there is a place 25 for applying the control identification marking.

The device operates as follows. When locking and simultaneously sealing covered wagons, hopper wagons, tank wagons, refrigerators and other objects to be sealed, the free end 8 of the rope segment 6 is sequentially passed through the combined holes of the locking unit. Then it is inserted into the inlet 4 of the upper cover 2 and pushed until it interacts with the main mechanism of non-permanent fixation 12, made in the form of a knurled steel roller 26, spring-loaded by spring 27, while the free end 8 of the rope segment 6, overcoming the compression force of the spring 27, leads the roller 26 is down and goes into the hole 5. After that, the length of the rope 6 is pushed through the housing 1 until it reaches the length of a possible hand grip and subsequent pulling until the contact of the housing 1 of the switchgear with the elements of the locking unit object but. After that, the free end 8 of the rope segment 6 is inserted into the stepped hole 20 on the bottom cover 3 and pushed inward until the cap 18 interacts with the hooks 19 with the fixing spring 17.

After installing the switchgear on the guarded object (tanks, etc.), the reliability of its closure is checked by trying to manually move the housing 1 relative to the length of the rope 6 in the opposite direction, and the reliability of fixing the free end 8 of the rope 6 in the fixing mechanism 12 is checked. the displacement of the housing 1 relative to the rope 6 in the opposite direction to locking, and fixing the free end 8 of the segment of the rope 6 should exclude the possibility of manual removal from the hole 20 of the housing 1.

The essence of fixing the free end 8 of the segment of the rope 6 is as follows. When pushing the end of the rope 6 with the cap 18 fixed on the tip 9 with the hooks 19 into the hole 5 on the bottom cover 3 and then inside the spring 17, the turns of which, having an inner diameter less than the diameter of the hooks 19, due to springing properties, expand the rope end 6 and pass with a cap 18 fixed on it with hooks 19, and then they act as latches and cover the rope 6 in turns, increasing its diameter in comparison with the input diameter of the stepped hole 20, preventing it from being removed from the housing 1 without visible damage .

For the same purpose, i.e. hindering the criminal opening, it also serves as the fact that the passive end 7 of the rope 6 is crimped by an additional locking sleeve 23 with an identifying inscription 24 directly above the top cover 2 of the housing 1, which excludes the possibility of cutting off the passive end of the rope 7, attaching it to the housing 1 again when an unauthorized opening is attempted fillings.

Removing the locking and sealing device is carried out by biting a segment of the rope 6 with a special tool.
