Abstract

The invention improves the reliability of locking the lock. The crossbar in the form of a toothed rack is meshed with a gear, in the center of which there is a turnkey well with a folding small beard in the form of a two-arm lever with protrusions, and at the end are holes for the protrusions of the key and retainers. The end of the gear is closed with a freely rotating gate with grooves through which the protrusions of the key act on the latches to unlock the gear when unlocking the lock. 1 hp f-ly, 2 ill.

The invention relates to locking devices, namely, patch locks.

The purpose of the invention is to increase the reliability of the lock.

In Fig. 1 shows the invoice lock, a general view in section; in FIG. 2, view A, in FIG. one.

The padlock includes a housing I with spring-loaded latches 2, a bolt 3 in the form of a toothed rack, an Allen key 4 with a head in the form of a two-armed lever 5, whose shoulders have a different weight and each of them is provided with a protrusion 6 interacting with one of the latches 2 of the case, and the drive mechanism, made in the form of gear 7 installed in the housing with a hub 8 and two openings 9, spring-loaded latches and protrusions 6 of the two shoulders lever 5 key. In addition, the lock is provided with a freely rotating flap 10, which is mounted coaxially with gear 7 with a clearance from it, while at least two concentric slots 11 and 12 are made in the flap 10, through which the projections of the two arms of the key interact with the clamps of the housing, and additionally concentric spaced false slots about 3.

The padlock works as follows.

When the lock is closed, the key 4 is passed into the holes of the disk 7 and the freely rotating damper 10 so that the double-arm lever 5 of the eye key outside the rear side of the patch lock and the difference of static masses takes up the vertical position. Then, pushing the key to itself until the protrusions 6 of the two arms are touching the surface of the flap 10, the key is turned to engage the projections 6 with concentric

slots 11 and 12. Next, the flap 10 is rotated until the projections 6 are aligned with the holes 9 of the disk 7 under the spring-loaded clips 2. After that, pull the key to itself, insert the clamps 2, unlock the disk 7 from the housing 1 and, turning the disk, which is in engagement with the bolt 3, the latter is displaced, the lock is closed. After that, the key 4 is removed from the lock by first turning the freely rotating flap 10 in any direction.

Opening the lock is made in

the same sequence. Such an implementation of the overlap lock increases the reliability of locking due to the presence of a freely rotating damper blocking access to the latches, in which a series of concentrically arranged cuts are made, at least through two of which are double-faced projections. of which the lever of the key interact with the clamps of the case. The presence of a number of concentric slots in the flap makes it difficult to remove the desired turnkey imprint for the manufacture of unclamp.
