Description

The utility model refers to sealing devices and can be used for locking and simultaneous sealing of stationary objects (warehouses, office premises), transport objects (bodies of freight vehicles), as well as technological containers, compartments, railway cars, containers, vans, tank hatches ( tanks with flammable and aggressive chemical cargo), warehouses (with flammable and aggressive chemical stored cargo), shops, etc., from the penetration of unauthorized persons or intruders into the cargo transported in them.

Known locking and sealing devices: RU patents for inventions No. 2 434 110 No. 2 184 892, RU patents for useful models No. 97 427, No. 104 961 No. 122 417, No. 135 690, No. 110 119.

Of these, the closest analogue is the patent for utility model No. 104 961, which has already expired and the patent for invention No. 2 184 892. Other presented patents are very different from the claimed solution.

RU patent for invention No. 2184892, which includes a piece of cable, which, when locked, is passed through the through channel of the body and is fixed in it by means of several spring-loaded rollers located in the seats provided in the body. The seats for the rollers in the body are made in the form of two longitudinal grooves located obliquely to the through channel of the body from two diametrically opposite sides of the through channel of the body. In this case, the grooves are made with the possibility of communicating with the cavity of the through channel of the body and have thrust end surfaces that are offset by a certain distance relative to each other and relative to the inlet of the body. The angles of inclination of the longitudinal slots are directed towards the inlet of the housing. The spring-loaded rollers are placed in the grooves with the possibility of rotation around their own axis of rotation and movement along the grooves when locking and with the ability to abut against the thrust end surfaces of the grooves with their side surfaces when attempting to maliciously pull back a piece of cable from the body. The side surfaces of one groove, the thrust end surface of which is located farther from the housing inlet, are flat, straight and parallel to each other. The side surfaces of the other groove, the thrust end surface of which is located closer to the inlet of the housing, are flat and consist of two parts so that one part of the second groove, which has a stop end surface, is located at an angle to the second part of this groove. Moreover, this angle is greater than the angle at which the part of the groove is located, which does not have a thrust end surface. The outer side surface of each of the rollers is made either in the form of a helical surface, or formed by alternating annular pointed projections and depressions, the planes of the cross sections of which are parallel to each other and inclined.

The utility model patent No. 104 961 is characterized by the fact that the cable-type locking and sealing device has a cable and a flattened body with a groove for securing the cable, a through channel for its movement and at least one slot with a mechanism located at an angle to the through channel fixing from a spring element and a roller, on the outer surface of which, along the generatrix, depressions are made in the form of a series of extended parallel grooves; the groove for the locking mechanism is a cylindrical cavity flattened on the right and left, oriented vertically so that the bottom of the groove

- the convex generatrix of the cavity, and the top of the groove is a flat area rounded at the edges and turning into flat vertically elongated ends, one of which on the outside from the through channel has an inward bend to give the direction of motion to the roller; the spring element is made in the form of a flat elastic ribbon-shaped plate bent in the vertical direction; the body is made in the form of a parallelepiped and consists of three parts; an internal base body in the form of a filled plastic structure of a rectangular shape with provided cavities for the named grooves and a through channel, rectangular plugs made of sheet metal with three side-by-side faces located at right angles to each other, which repeat the front, upper and lower parts of the body - bases and placed on them, the third - the outer part of the body, made in the form of a shell molded from plastic.

The disadvantage of the closest analogs, as well as other known solutions, is the insufficiently reliable fixation of the cable, which does not allow to exclude the cable slipping back when trying to pull it out of the body - many of them use a roller as a fixing element, in addition, they have a complex design.

The technical result of the utility model is to increase the security against non-destructive unauthorized criminal opening of the locking and sealing device.

The essence of the utility model.

The specified technical result is achieved by the fact that when sealing the object, the free end of the steel rope is passed through the lugs of the locking unit of the object and further into the channel inlet, then, holding the body, tighten the free end of the steel rope until a loop of minimum size is formed, until it stops, according to the arrow on the body of the ZPU for passing the free end of the steel rope is passed again in the opposite direction until it stops when assembling the device With the free end of the steel rope, the locking cracker is lowered into the seat of the locking mechanism body through the through channel. The spring is then compressed. The steel rope freely goes outside the body without difficulty. The spring moves the locking cracker until it interacts with the steel rope, and when trying to extract the steel rope, the steel rope jams, the locking cracker moves perpendicular to the steel rope, and thus more jamming occurs. Double passage of the steel rope through the body, according to the arrow on the body, excludes the possibility of opening the ZPU by pushing and installing any flat object between the steel rope and the locking cracker in order to slip the steel rope relative to the locking mechanism and subsequent unauthorized non-destructive criminal opening of the ZPU,

And also by the fact that the manufacture of internal parts uses a laser machine and a spring-coiling machine.

And also by the fact that the bodies are made of hard aluminum alloy using a matrix tool, which significantly extends the service life. The advantage of aluminum alloy is expressed in its non-sparking properties, light weight and in the processing prostate "

And also by the fact that the steel rope is made using a rope-coiling machine, cut to the required length using a plasma torch, and the end is processed with a forging hammer (machine) and finished with a grinding machine.

And the fact that the steel rope and the locking mechanism are fixed in the cavity of the body using a hydraulic press using a matrix installed in a press stamp. Possible range of wire rope size is 1 to 15mm, the thicker the wire rope, the higher the indices of continuity. This difference is useful in cases where there is no need for a large steel rope thickness, for example, for

fixing small boxes, containers, etc. Or it is necessary to seal a large object where the size of the wire rope is important and the larger the better.

A distinctive feature of the claimed product is the novelty of the locking mechanism and the simple design of the product.

The locking mechanism consists of:

- an insert with a seat for a spring and a cracker;

- cracker with a seat for the spring and a sharp blocking angle;

- spring. ZPU consists of:

- body with two cavities;

- steel rope;

- locking mechanism.

An insert with a spring and a cracker installed in it (hereinafter the Locking Mechanism) is installed in the cavity of the body and fixed by punching, and provides jamming of the free end of the steel rope when it is passed through the channel. The principle of operation of the locking mechanism: when passing a steel rope, for example, from right to left, the steel rope pushes the cracker, and in the next turn, compressing the spring, sits in the seat in the liner. When trying to pull out the steel rope, in the opposite direction from the original direction of the rope passage, the cracker under the pushing action of the spring is pressed against the steel rope and blocks it with an acute angle by pressing it against the channel wall of the ZPU body. Thus, it blocks the steel rope in the ZPU. The greater the force when trying to extract the steel rope from the ZPU body, the stronger the clamping and blocking of the steel rope occurs.

Visual images of the product are presented on separate sheets in Fig. 1-5, visual images of the locking mechanism are presented on separate sheets in Fig, 6-9.

3. Compliance with hygienic and environmental safety standards, absence of toxic and other adverse factors affecting users, human health and the environment.

4. Security against counterfeiting.

5. Reliability, simplicity and ease of use and installation, without the use of additional auxiliary tools and devices.

6. Novelty, innovativeness of the locking mechanism and the declared product.

7. Low weight due to alloy body, few parts and simple locking mechanism.

8. The design of the body allows, depending on the size of the steel rope, to directly proportionally change the size of the body and the locking mechanism.

9. Resistance to various climatic conditions.

10. Made of materials with high anti-corrosion resistance.
