Seal

Description:

The invention relates to sealing devices intended for protection against unauthorized access to tariff meters, containers, wagons etc.

It is known the seal that confines the plate, an elastic cord and a lock with elastic bush on the body, in which the plate and the elastic cord are located along the lock axis [1].

Said seal has о low protection against unauthorized access and falsification of information placed on the plate.

The closest solution is the seal, which confines a cylindrical body, in which a pivot with two holes located in the same plane and a ratchet mechanism, which allows the pivot to rotate in one direction, and from the outside is provided о blade. easily removable [2].

The disadvantages of the technical solution consist of the low reliability and the low resistance to unauthorized access and the counterfeiting of the validity of the sealing function due to the application of the gluing method when combined, which at the same time limits the transparency of this important part of the seal, as well as the low security regarding the counterfeiting of information. on the tablet.

The problem of solving the invention is to exclude unauthorized access and counterfeiting of the information held.

The seal according to the invention removes the disadvantages mentioned above in that it contains a tubular body, which consists of a cylindrical body, on which is fixed a rectangular element in the form of a plate and a second cylindrical body, on which is fixed an element consolidation with о cavity, which repeats the shape of the rectangular element. The rectangular element and the consolidation element are placed and fixed to each other by ultrasonic bonding. The seal also includes a pivot located in the interior and equipped with о slightly detachable blade, which is provided with two holes, executed in the same plane, through which passes a flexible elastic element, wrapped on the pivot; The pivot also has a support disc and a separator disc with a ratchet mechanism for rotating the pivot in a certain direction. At the same time the ratchet mechanism consists of two diametrically opposed elements, which engage with the teeth, executed in the cylindrical body.

The result of the invention consists in excluding the unauthorized access and the counterfeiting of the information held due to the transparency of the body that is obtained by ultrasonic fastening and gluing.

The invention is explained by the drawings in FIG. 1 -8, which represents:

The seal confines a tubular body, which consists of a cylindrical body 1, on which is fixed a rectangular element in the form of a plate 11 and a second cylindrical body 2, on which a consolidation element 12 with о cavity is fixed, which repeats the shape of the rectangular element. The rectangular element 11 of the first cylindrical body 1 and the strengthening element 12 with a cavity, which repeats the shape of the rectangular element of the second cylindrical part 2, are located and fixed to each other by ultrasonic bonding. The pivot 3, equipped with о slightly removable blade 6, is provided with two holes 4 and 5, executed in the same plane, through which passes a flexible elastic element, which is wound on the pivot 3. The pivot 3 also confines the support disc 10 and a separator disc 7 provided with a ratchet mechanism 8, which allows the pivot 3 to rotate in a certain direction. The ratchet mechanism 8 is composed of two elements

The seal works as follows. In the second cylindrical body 2, on which is fixed a strengthening element 12 with о cavity, which repeats the shape of the rectangular element, the pivot 3 is introduced, equipped with о slightly detachable blade 6, and the two diametrically opposed elements engage with the grooves 9 , offering the possibility of rotating in one direction. Informational data is entered on the rectangular element in the form of plate 11 of the first cylindrical body 1. The rectangular element in the form of plate 11 of the first cylindrical body 1 is inserted into the cavity, which repeats the shape of the rectangular element, in the form of plate, of the consolidation element 12 of the second cylindrical body 2 and is joined by ultrasound.

At sealing, the pivot 3 rotates with the help of the blade until both holes 4 and 5, located in the same plane, coincide with the holes 4 and 5 of the bodies 1 and 2, respectively, through which a flexible element passes, after which the pivot rotates in one direction, by rotating the elastic member on the pivot, after which the blade is detached by a slight bending. Ultrasonic bonding gives the seal complete transparency, which allows to see the information information on the seal at any time and to visually detect the state of the seal, thus avoiding the possibility of unsanctioned access.

The invention has the following advantages:

- the safety and strength of the seal against unauthorized access is increased due to the increase of the soldering surface, which is obtained by using ultrasonic bonding;

- the protection against counterfeiting of the information held is ensured, because the plate on which the informational data is placed is inserted inside the consolidation element, which is ultrasonicly bonded;

- it provides comfort when mounting the seal;

- the transparency of the seal is obtained due to the use of ultrasonic bonding, which excludes unauthorized access and counterfeiting of sealing, which is impossible when gluing.
