Description

FIELD OF THE INVENTION

This invention relates generally to hardware and, in particular, to devices for locking and sealing the doors of railway cars, freight containers and vans, tank hatches, steering wheels for grain hoppers, warehouses, warehouses, shops, stalls and other objects.

More specifically, the invention relates to flexible locking and sealing devices (ZPU), in which a flexible element is used as a contactor, for example, a piece of rope (steel cable), equipped with additional means of fixing a piece of rope in the closed state of the device, providing a high degree of protection of the ZPU from its unauthorized autopsy. In this case, the latter can be made in the form of a locking screw with a detachable handle screwed into the housing of the switchgear, additionally locking the length of the rope in the closed state of the device.

State of the art

A flexible locking and sealing device (RF patent No. 2396405) is known, which contains a piece of rope, one end of which is passive, and the second free end, when locked, is pulled through the hollow body to form a loop and is fixed in it by means of a locking mechanism that contains the cavity of the housing and a spring-loaded separator closure spring, the fixing elements, while the cavity of the housing is closed by the upper and lower covers, equipped respectively with inlet and outlet openings for passing about cutting the rope a cavity made coaxially to the axis of the housing and the channels made in the separator having a bottom wall. At the same time, the device is equipped with an additional locking element made in the form of a rod having a locking screw at one end, with which it is screwed into the threaded hole, and at the other end, a breakaway technological shank with a breakaway groove. The bottom cover is made in the form of a block with frontal and inclined faces, repeating the body cavity in the lower part and extending inward of the last one, bearing the specified additional fixing element by means of a threaded hole into which the locking screw is screwed, while the technological shank is placed in the shank holder mounted in the side holes made in an inclined side face of the housing, and the axis of the threaded hole and side holes are made at an angle to the axis of the cavity of the housing and in assembled form cases and covers coincide, while the spring stabilizer is made in the upper part of the block in the form of a coaxial outlet opening of the recess in which the lower end of the spring is located.

The device allows to increase the degree of protection against unauthorized opening.

The given analogue is made on the basis of the product ZPU TP 2800-02. To do this, it was necessary to change:

- the design of the bottom cover, make it more metal intensive;

- spring stabilizer;

- circuit spring and other elements of the device.

What should be attributed to the disadvantages of the known solution.

Closest to the proposed solution is ZPU, described in patent RU No. 2295619 (Ε05В 39/02). The device comprises a housing and a piece of rope, one end of which is passive, and the second free end, equipped with a tip, is passed through the inlet and outlet openings of the housing and the passage channel located between them with the formation of a loop and fixed in it when closed by a locking mechanism located in the housing wherein the clamp of the rope segment in it is made in the form of a rod having a locking screw at one end, with which it is screwed into a threaded hole, the axis of which is perpendicular to the passage channel, and at the other end, a technological shank with a breakaway groove, and a spring-loaded rod mounted in a blind hole of high hardness material with a conical end interacting in a closed state with a breakaway groove. The device allows to increase the degree of protection against unauthorized opening.

The disadvantages of the known device include the fact that for placement in its lateral (end) part of the additional fixation of the rope segment, it was necessary to change the design of the body, to make it more metal-intensive.

The technical result of the proposed utility model is the elimination of these shortcomings, as well as the expansion of the arsenal of means of additional fixation of the rope segment in the closed state of the device while maintaining both the body and the device structure (the status quo), i.e. with almost 100% unification of known devices, including: Octopus 777, TP 2800-02, Ohra-1, Tetron, Laurel 2000, etc.

The implementation of the invention

The clamp of the segment of the rope in the closed state of the flexible locking and sealing device containing the housing 1 and the segment of the rope 2, one end of which is passive 2.1, and the second free end 2.2, equipped with a tip, is passed through the input 3 and output 4 of the opening of the housing 1 and located between them the passage channel 5 with the formation of a loop and is fixed in it when closed by means of a locking mechanism 6 located in the housing 1. At the same time, the clamp 7 of the rope segment is made in the form of a rod having a locking screw 7 at one end .1 with which it is screwed into a threaded hole 8, the axis of which is perpendicular to the passage channel 5, and at the other end, the technological shank 7.2 with a break groove 7.3 and mounted in a blind hole 7.4 made of high hardness material, a locking spring rod 9 with a conical end 9.1, interacting in the closed state of the device with a break groove 7.3. Those. a spring-loaded rod 9 with a tapered end 9.1 is kept from overlapping the threaded hole 8 and the overrun of the blind hole 7.4 by a break groove 7.3 on the process shank 7.2. Blind hole 7.4 may be closed by a plug or ball 7.5 (Fig. 6). According to the invention, the clamp 7 of the rope segment is mounted in an autonomous housing 10, having the possibility of its installation on the housing 1 of the device or on the cover of the housing provided with a through hole 11 intersecting the passage channel 5, coinciding with a threaded hole 8 for the locking screw 7.1.

In this case, the autonomous housing 10 can be rigidly fixed to the device housing 1 or to the housing cover either by welding or by means of glue. In this case, you can use conventional adhesives, such as Moment, or Poxipol glue (liquid welding) - an adhesive that has metallic hardness, does not rust and does not change its properties.

The stand-alone housing 10 can be made cylindrical, trapezoidal, in the form of a parallelogram, etc.

In addition, information can be printed on the stand-alone housing 10, for example, a duplicate seven-digit control identification number of the device.

In addition, an autonomous housing can be located on the device in any position: in the area of the inlet or outlet, and also rotated relative to the axis of the passage channel at any angle.

Also, a self-adhesive protective label “ZPU-CONTROL” can be applied to an autonomous housing.

Technological shank 7.2 can be made either in the form of a rod of a L-shaped form, or in the form of a rotary handle with a lamb, or in the form of a rectilinear round rod with an internal multifaceted blind face or slot, or in the form of a rectilinear multifaceted rod.

Also, the autonomous housing 10 can be made of synthetic material and fixed to the housing or the housing cover of the device by means of glue.

The device is used as follows.

When locking, the free end 2.2 of the rope segment 2 is sequentially passed through the holes of the eyes of the locking object, the inlet 3, and then through the passage channel 5. The free end begins to interact with the locking mechanism 6, which, as a rule, includes those located in the inclined hole in communication with the passage channel 5, spring-loaded locking elements-balls or rollers, squeezes them down along the longitudinal axis of the housing. At the same time, the locking elements, sinking in the inclined hole, provide the possibility of passage of the length of the rope 2 through the passage channel 5 and then through the outlet 4. Then the length of the rope 2 is manually tightened to form a loop of minimum size. With the cessation of the application of force on the segment of the rope, the locking elements of the locking mechanism under the action of the closure spring move up and reliably fixes it in this position.

But since there are technological gaps between the segment of the rope 2 and the inlet 3, from the inlet side the introduction of any tool into the case is not excluded, and, therefore, the contact of the instrument with the locking mechanism and the subsequent pulling of the rope in the opposite direction, theft of contents, and again locking. Moreover, this may be unnoticed before the arrival of the goods.

To exclude covert criminal effects on the locking mechanism through the inlet 3 of the housing 1 and serves as a means of additional fixation of the rope in the closed state of the device.

In the proposed solution, the means of additional fixation of the rope segment in the closed state of the device-retainer is mounted, unlike the known means, not in the device case, but due to its implementation in a stand-alone case, on the case or on the cover of the device case. Moreover, as it is not difficult to notice, due to the mounting of the latch in a separate or independent housing, i.e. stand-alone case, the proposed solution can be readily mounted on the front surface of the device case (Fig. 1), on the front side of the device case (Fig. 2), on the cylindrical case of the device, it is advisable that the lower plane of the stand-alone case repeat the side surface of the case device (Fig. 3, 4), on a round casing with two flat end surfaces (Fig. 5) with or without a cover.

Also, the stand-alone case 10 can be mounted on the cover of the device case either by means of a threaded connection with threading respectively in it, and in the cover of the screw holes screwed into the stand-alone case 10, or by riveting with the protrusions being made on it, and in the cover of the holes ledges (to hell, not showing.).

Those. the proposed solution is universal: it can be mounted on the device’s case in almost any configuration. Moreover, on the case, it is only necessary to have a smooth through hole 11 intersecting the passage channel 5, coinciding with the threaded hole 8 for the locking screw 7.1 of the retainer 7.

So, the segment of the rope 2 is fixed by the locking elements of the locking mechanism 6. After that, using the technological shank 7.2 tighten the locking screw 7.1. In this case, the pointed end of the locking screw 7.1 is introduced into the segment of the rope, crushing its strands and spreading them, and the technological shank 7.2 breaks off or is cut in the area of the break groove near the end of the locking screw 7.1. The end face of the locking screw 7.1 with part of the breakaway groove will be located inside the threaded hole 8 of the autonomous housing 10, and is not accessible for unscrewing.

However, practice shows that attackers succeed in drilling it, and in the future, with subsequent exposure to the locking mechanism, they produce an act of unauthorized opening of the device. Therefore, the proposed solution provides for the closing of the end face of the locking screw 7.1 from drilling it with a safety element, which is made in the form of a locking spring-loaded rod 9 with a conical end, which in the closed state of the device abuts against the breakaway groove 7.3 and does not impede the rotation of the technological shank 7.2, and as it deepens locking screw 7.2 into the body of the rope, the conical part of the technological shank 7.2, interacting with the conical part of the spring-loaded rod 9, slightly moves it inward blind hole 7.4. Then, immediately after breaking off the technological shank 7.2 and its subsequent removal from the autonomous housing 10, the spring-loaded locking rod 9 under the action of the spring 9.2, moving in the blind hole 7.4, overlaps the end face of the locking screw 7.1. And thus, since the spring-loaded rod 9 is made of a material having increased hardness, drilling of the locking screw 7.1 is not possible. Those. unauthorized opening of the device is also impossible. Also, due to the fact that the conical end of the rod 9 in the closed state of the device abuts simultaneously against the breakaway groove 7.3 and the end face of the locking screw 7.1, it cannot be turned out, and therefore it is impossible to simulate the locking of the rope by prematurely breaking the shank 7.2, since the spring-loaded locking rod 9 is not may block blind hole 7.4. Only as the locking screw 7.1 deepens into the body of the rope and then breaks off the technological shank 7.2 in the area of the break groove 7.3, under the action of the spring, the rod 9 will provide a shut-off of the blind hole 7.4. In the opposite case, i.e. if the blind hole is not blocked normally, this is a signal to simulate additional locking or fixing a piece of rope 2 inside the passage channel 5.

The proposed solution of additional fixation of the rope segment in comparison with the known means of additional fixation of the rope segment allows, exclusively due to the implementation of the stand-alone case, which is mounted on the switchgear without changing the basic design of the product, to provide almost 100% unification of the case and other parts of the base device. When using it, the time and cost of preparing the production will be minimal.

The disclosed preferred embodiment is provided by way of illustration and not limitation.

Before authorized opening of the device, which is carried out by biting a piece of rope with a special tool, it is necessary to visually check the lock: its blocking reliability in the body and integrity.

Thus, the present invention allows to increase both the degree of protection of the ZPU against unauthorized opening, and in general the versatility of its use.
