Description

The invention relates to equipment for unlocking locks with a levers of secrecy, which do not have a guide pin in the key well, and levers with individual springs, as well as allowing to decrypt the code combination of levers.

A device for unlocking locks, which consists of a housing with axially movable measuring sleeve and a rod with a working head (DE 19822079 C1, 02.17.2000).

A disadvantage of the known device for unlocking locks is that it allows you to unlock the locks without the ability to save the lock code. With a large number of locking pins, the possibility of shifting the already selected delay from the “open” position to the “closed” position always remains. The disadvantage of this device is the lack of operational selection of the code combination and the ability to save the lock code.

The closest analogue is (RU 2272883, publ. 03/27/2006) a device for unlocking locks, comprising a housing with an axially movable measuring sleeve and a rod with a working head, characterized in that the housing is fixedly connected to the rod, made rotary and hollow, inside the rod is movably placed on the guide tube with a hole on the free end, on the free end of the pivoting rod a working head is made in the form of a block of interchangeable pins placed in its channels, the measuring sleeve is connected to the guide tube in the middle by means of a clamp, inside the guide tube there is a pusher in the form of a rod, on the free end of which a recess is made with an inclined platform and a ball installed in it, the diameter of which does not exceed the diameter of the hole in the guide tube, the other end of the pusher is fixedly connected to the measuring sleeve by means of a spring-loaded stop, the surface of which is applied two groups of identical dimensional patterns, the distance between which corresponds to the distance between the longitudinal axes of the channels of the working head, and one group of dimensional x notches are placed from the condition of providing the possibility of visual inspection, while the other is located inside the case, while the hole is made in the latter, in which the fixator for the location of the next interchangeable pin is installed, and the detent is made in the form of a spring-loaded ball in contact with one of the notches located inside the case .

The device of the prototype, difficult to manufacture for a specific lock, consists of small and not sufficiently fixed parts, has a high probability of spilling the device in the keyhole during operation. There is no operational selection of a code combination.

The objective of the invention is an alternative solution for obtaining fingerprints of the combination code lock relative to the prototype.

The technical result of the invention is:

- simplification of the design,

- simplification of the manufacture of blanks for a specific lock,

- eliminating the likelihood of spillage of the device in the keyhole during operation,

- the ability to quickly select the combination code of the lever locks of most double-bead models with a slight fit for the suvald packet of the locking device,

- the ability to obtain fingerprints of the combination code of the locking device.

The specified technical result is achieved due to the fact that the claimed device for opening a level lock is made in the form of a hollow tube with a pivoting rod inserted in it, made rotatable, and a barrel with working barrels, characterized in that the rotatable tensioning rod is made of blued steel, has L-shaped end on one side and a handle on the other, barbs made of bronze, a fine lattice extruded on one side, a layer of solder or tin on the other side, a barrel with working beards and has a rotary handle. A rotary tension rod is installed in the barrel with barbs with the possibility of free rotation by 10-15 degrees in one or the other direction relative to the working barbs.

If necessary, an annular restrictor for feeding the device into the keyhole may be mounted on the barrel, which is made with the possibility of fixing in the desired position.

The limiter for feeding the device to the keyhole can be made of polypropylene and consisting of two halves connected by crimping using bolts or screws.

Brief Description of the Drawings

In FIG. 1 shows a device with a keyhole feed limiter installed, where a is a close-up view of a barrel with a keyhole limiter for feeding a device to a keyhole.

In FIG. Figure 2 shows the principle of operation of the utility model with a cutout on the stem and a fragment of the beard in the section (view - B).

In FIG. Figure 3 shows the device of the utility model in assembled form in working condition and separately rotatable tension rod.

In the drawings: 1 - a barrel with working beards, 2 - a rotary tension rod, 3 - solder on beards made of bronze, 4 - a handle of a barrel with working beards, 5 - a limiter for feeding the device into the keyhole, 6 - a beard made of bronze with a fine grill applied on the one hand and solder on the other, 7 - the L-shaped end of the tension rod, 8 - the handle of the rotary tension rod.

The implementation of the invention

The device (see Fig. 1) can be made in the form of a hollow tube with an inserted rod 2 of the tension rod, which is made rotatable, where the hollow tube 1 is a barrel with working beards 6.

The pivoting tension rod 2 is made of blued steel and has a L-shaped end 7 on one side and a handle 8 on the other. Barbs 6 are made of bronze. On the one hand, a fine lattice is extruded on bronze; on the other hand, a layer of solder 3 or tin is applied. The barrel 1 with working barbs has a rotary handle 4. The rotary tension rod 2 can be installed in the barrel 1 with barbs 6 with the possibility of free rotation by 10-15 degrees in one or the other direction relative to the working barbs 6.

If necessary, an annular stop 5 can be installed on the barrel 1 to feed the device into the keyhole, which can be fixed in the desired position. The limiter for feeding the device to the keyhole 5 can be made of polypropylene and consisting of two halves connected by crimping using bolts or screws.

The principle of operation of the device is as follows.

The device is in the operating position as in FIG. 1, inserted into the keyhole, if necessary, fix the key supply by the stop 5 in the keyhole.

During the conversion of the axial translational movement of the rotary tension rod (see Fig. 2 (a)) (depending on the movement of the open / close bolt) to the bolt of the locking device installed in the barrel 1 with working barrels 6, the bolt is tensioned. Holding the bolt in tension with a tension rod 2, by pulling it by the rotary handle 8 of the L-shaped end 7 until it stops in the bolt.

Then rotate using the handle 4 the barrel 1 with the working beards 6 on the levers of the locking device in the direction of movement of the bolt (opening / closing).

As a result of the manipulation of the device, the movement of the working beards 6 along the most clamped levers of the locking mechanism, clear deformation traces (prints) remain on the surface of the solder 3.

On solder 3, where there are traces of suvald, the solder is slightly cleaned with a file. This manipulation must be carried out until the working surface of the beard 6 matches the combination code of the locking mechanism and the bolt does not budge.

The device allows you to quickly decrypt the code combination of the lever locks of most models of the two-bead type with a slight fit for the package of the suvald of the locking device, to obtain fingerprints of the code combination of the locking device.

The result of the product is to obtain fingerprints of the combination code of the locking device on the working surfaces of the barbs.

The implementation of the device, consisting of two main components: the barrel 1 and the rotary tension rod 2, simplifies the design and allows it to be made easier for a specific lock. The design of the barrel 1 and the tension rod 2 is quite reliable, does not contain small parts, which reduces the likelihood of the device scattering in the keyhole during operation.
