Description

Technical field

The utility model relates to devices for sealing various stationary objects and vehicles having hinges, in particular, doors of warehouses, hatches of cisterns, eyes of wagons, caravans, containers and refrigerators, etc.

The level of technology

The prior art monoblock sealing device (RF patent RU2111329, 20.05.1998), comprising a housing in which two longitudinal through channels are made, a flexible covering element, one end of which is permanently fixed in the housing, and the second alternately passed through both through channels to form two loops, one of which covers the lugs of the locking assembly and is located between one of the through channels and the embedding of the female element in the housing, and the second is located between the through channels. Education in the design of the sealing device of the second loop, closing the approach to the entrance window seals for entry into the body through the technological gap of the probe to act on the locking element, makes it difficult for an attacker to manipulate to open it.

The disadvantage of this device is low resistance to mechanical destruction by breaking the hard blocking element and the criminal opening.

A locking and sealing device (RF patent RU186357, 01/16/2019) is known, comprising a flat body with a through cavity and a through hole for accommodating the passive rope section, a figured insert permanently installed in the cavity of the housing to form through channels for passing the working section of the rope, which is alternately passed through both through channels with the formation of two loops, one of which covers the locking lugs, and the second is located between the through channels. The figured insert has a cut in the form of a wedge, combined with one of the through channels, and a seat made from the wide side of the wedge cut to accommodate a compression spring that interacts with the roller. The through-cavity of the body is made in the form of a rectangular parallelepiped having semi-cylindrical samples on the long sides, and the width and height of the cavity is equal to the width and thickness of the figured insert, with the side part of the insert from the narrow part of the wedge groove having a rounded shape to be placed in it and in the second body cavity rope loops. The passive section of the rope is fixed in the housing by plastic deformation of the hull elements with the formation of cylindrical crimps, which have a spherical protrusion in the middle part.

This device does not have high reliability, since it is possible to impact the locking element in order to release it and remove the rope from the body.

The closest analogue of the claimed utility model is a locking and sealing device, disclosed in the patent of the Russian Federation RU75683, 20.08.2008. The specified device includes a housing in which two longitudinal through channels are made, a flexible covering element, one end of which is permanently fixed in the case, and the second in the final assembly position is alternately passed through both through channels with two loops, one of which covers the locking lugs of the assembly and located between one of the pass-through channels and sealing the enclosing element in the housing, and the second between the pass-through channels. An end-to-end sample is made between the longitudinal through channels in the housing, and an insert is located in it, which is fixed in the housing by plastic deformation. The insert is made of a wedge-shaped cavity, combined with one of the longitudinal channels, and in the wedge-shaped cavity of the insert is placed a spring-loaded locking element made in the form of a body of revolution and interacting with a flexible female element.

This solution also does not have sufficient reliability to mechanical destruction and unauthorized opening.

Disclosure of the essence of the utility model

The objective of the claimed utility model is to eliminate the drawbacks of the analogues and to develop a more reliable design of the locking and sealing device.

The technical result of the utility model is to increase the resistance of the locking and sealing device to mechanical destruction and criminal opening.

This technical result is achieved in the utility model due to the fact that the cable locking and sealing device contains a monolithic metal case having a cavity for accommodating the locking mechanism, as well as two through holes for the cable located along the edges of the said cavity; a metal cable, the first end of which is pressed in the housing, and the second end is arranged to be successively placed in the said housing openings with the formation of two loops; and a cable locking mechanism placed in said housing cavity and including a prismatic key with a notch in which a spring-loaded locking element in the form of a gear wheel having a central groove separating the teeth on the rolling surface is placed. The cut of the key is aligned with the second opening of the housing to ensure that the second end of the cable is fixed by a toothed wheel. The gear wheel has a truncated cone-shaped head on the end surfaces. The width and depth of the central groove are chosen such that one region of the cable sags in the groove and the other two, adjacent regions of the cable interact with the corresponding rows of teeth.

The advantages of the claimed cable locking and sealing device over those known from the prior art are provided by the special design of the gear wheel, which is a monolithic structure, made preferably of hardened steel, with two rows of teeth, a separating groove between them and conical heads on the end surfaces. When a gear wheel comes in contact with a cable, one area of the cable (for example, one of the cable strands) sags in the groove, and the other two, adjacent areas of the cable (for example, the adjacent cable strands) interact with two rows of teeth, which increases the contact area of the cable with the gear teeth and accordingly increases the resistance of the device to mechanical destruction and criminal dissection. At the same time, the cone-shaped heads on the end surfaces of the gear wheel ensure reliable retention of the gear wheel in its working plane (and at the same time ease of rotation when passing the cable through the device), which also increases the device's resistance to mechanical destruction and criminal opening, since it prevents the gear from tilting and / or shifting wheels that could facilitate the removal of the cable from the device.

In addition, this technical result is achieved in private embodiments of the utility model, according to which:

- the gear wheel contains two rows of twenty eight teeth;

- the cut in the key has a bottle-like shape, while a compression spring is placed in the neck of the specified cut, which ensures the springing of the gear;

- the cable is made in the form of a double twist cable and consists of six multi-wire (preferably seven-wire) strands located around a central multi-wire (preferably seven-wire) strand, while its ends are folded with metal half-cylindrical bosses;

- the first end of the cable is pressed through one cylindrical and two parallelepiped grooves in the housing;

- the body is made of aluminum alloy;

- the key is made of aluminum;

- gear made of hardened steel.

The listed private embodiments of the utility model are also aimed at increasing the resistance of the locking and sealing device to mechanical destruction and criminal opening. However, they are not the only possible forms of embodiment of the design of the claimed device. In this case, the claimed technical result is achieved without the mandatory presence of the above additional design features of the device.

Implementation of the utility model

The locking and sealing device has a housing 1, which is a monolithic part, preferably of aluminum alloy, in the form of a flat parallelepiped with a cavity 2, designed to accommodate the locking mechanism, as well as two through holes 3 and 4, located along the edges of the specified cavity 2 , to accommodate a metal cable 5.

The cable 5 performs the required thickness (diameter) and shape, however, it is preferable if it is made in the form of a double lay cable, which consists, for example, of six seven-wire strands arranged around a central seven-wire strand. The ends of the cable 5 are seamed with metal bosses 7 of a semi-cylindrical shape, which increases the smoothness of inserting the cable 5 into the openings of the housing 1, protecting the user from mechanical damage, as well as the integrity of the cable 5 itself, which directly affects the resistance of the device to mechanical destruction and criminal opening.

The first end 8 of the cable 5, forming a passive section, is fixed by pressing in the housing 1. The pressing is performed in three places on one side of the housing 1 and consists of three grooves: two parallelepiped grooves 9 along the edges and one cylindrical groove 10 in the center. This arrangement and the type of insertion increases the clamping area of the passive area (end 8) of the cable 5 in the housing 1, increasing the reliability of fixing the cable 5.

The locking mechanism consists of three parts: a prismatic key 11 made of aluminum, as well as a steel spring 12 of compression and a gear wheel 13 located in the bottle-shaped notch 14 of the key 11. The specified notch 14 is aligned with the second (in the direction of the cable 5 when locked) opening 4 of the body one.

The external dimensions of the key 11 correspond to the internal dimensions of the cavity 2 of the housing 1 in three dimensions. The key 11 also has a circular through hole 15, which serves to fix the key 11 by pressing the body 1 in a single cylindrical recess (not shown), the diameter of which coincides with the dimensions of the hole 15.

The compression spring 12 is located in the neck of the bottle-shaped notch 14 of the key 11 and interacts with the gear wheel 13.

The gear wheel 13 is a locking element of the mechanism and is a monolithic structure, preferably of hardened steel, without a hole in the center. On the rim (rolling surface) of the gear wheel 13 there are two rows of teeth 16, preferably twenty-eight teeth 16 each, separated by a central groove 17. A significant reduction in the number of teeth 16 leads to difficulties in passing the cable 5 through holes 3 and 4 of housing 1, and significantly a larger number of teeth 16 facilitates the possibility of the return of the cable 5 and, as a result, opening the device.

The gear wheel 13 is made with such a width and depth of the groove 17 that one area of the cable 5 (in particular, the central area of the cable 5 on its outer surface) sags in the groove 17, and the other two, adjacent areas of the cable 5 (respectively, the neighboring areas of cable 5 along with respect to the specified central area) interacted with the corresponding rows of teeth 16. As a possible option, when the above described implementation of the cable 5 double lay, consisting of six seven-wire strands located around the center seven-wire strand, well, the depth of the groove 17 is preferable to choose less than the diameter (in cross section) of one strand of cable 5. This ensures tight coupling of the wheel 13 with the individual strands of cable 5 and does not allow opening the connection using auxiliary means, such as a probe, when trying to open the connection during a criminal attack .

On the end surfaces in the center of the gear wheel 13 on both sides there are two heads 18 in the form of truncated cones. The reduced area (at the tops of the truncated cones) of the contact of the wheel 13 with the housing 1 ensures smooth running without jamming of the wheel 13 in the bottle-shaped notch 14 of the key 11 when closed with a cable. In addition, this form of execution of the heads 18 ensures reliable retention of the gear wheel 13 in its working plane, which also increases the resistance of the device to mechanical destruction and criminal opening, since it prevents the gear wheel 13 from tilting and / or displacing, which could facilitate the removal of the cable 5 of the device.

In the final assembly position, the second, free end 19, forming the working section of the cable 5, is alternately passed from both sides of the key 11 through the through holes 3 and 4 to form a double loop in the shape of eight, where the first loop of the cable 5 binds the eyes of the lockable node (not shown) and the second loop is tightened around the oval part of the key 11.

The device works as follows.

The free end 19 of the cable is alternately inserted into the lugs of the lockable node, then into the first through hole 3, located closer to the fixed passive part of the cable 5, and then into the second free hole 4 in the case 1 that remains free. For ease of use, the housing 1 can be labeled Arrows to indicate the sequence of input cable 5.

Both loops formed should be carefully tightened so as to exclude the possibility of impact on the cable 5 by removing it from the housing 1. When the cable 5 passes through the second hole 4, the gear wheel 13 moves under the pressure of cable 5 in the bottle-shaped notch 14 of the key 11 towards the compression spring 12 that shrinks. Thus, the gear wheel 13, having shifted, releases the passage for the cable 5 inside the housing 1. After pulling the cable 5 until it stops, the second loop should grasp the oval part of the key 11. The reverse gear of the cable 5 on one side is impeded by the gear 13, which cannot return to the initial position is due to the cable 5, resting on it, and on the other hand, the wall of the housing 1. The turning of the gear wheel 13 around its axis is prevented by two rows of teeth 16 with a groove 17, which on one side rest on the fibers of the cable 5, and on the other sides - in the spring well 12. In an attempt to extract the cable 5 with the application of force gear 13 finally Wedges cable 5, such that it is open, which prevents opening of the device.

Thus, the claimed cable locking and sealing device eliminates the disadvantages of the known analogues and provides increased resistance to mechanical destruction and criminal opening.
