Abstract

The invention relates to staples and makes it possible to increase the compactness of a cylinder lock mechanism. The housing 1 houses a drum 2 in which a plate package 3 is installed, each of which has a protrusion 4 and a recess 5, and a locking bar 6 rigidly connected to the leash 7 and mounted to be placed in the recesses 5 of the rails. The plates are installed with the possibility of reciprocating movement and are spring-loaded by a spiral spring 10 enclosing them. The key of the lock is made of two halves, each of which has code holes for interacting with the protrusions of the four plates and two basic holes for placing the stops 11 fixed on the drum. . 10 il.

Description

FIG. 2

The invention relates to staples m.

The aim of the invention is to increase the compactness.

FIG. 1 shows the lock, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section of YYD in FIG. 2; in fig. 6 is a view of D in FIG. 2; in fig. 7 is a view E of FIG. 2; in fig. 8 - key; in fig. 9 - plate; in fig. 10 - plate with a high protrusion.

The cylinder lock mechanism comprises a drum 2 placed in the housing 1, a plate package 3 installed in the drum, each of which has a protrusion 4 and a recess 5, a locking bar 6 installed with the possibility of being placed in the recesses 5 of the plates, a leash 7 and a key 8 with code holes 9 for interacting with the protrusions 4 of the plates 3. The mechanism is provided with an annular spiral spring 10, which encloses the package of plates 3 and two lugs 11 diametrically fixed in the drum 2. The plates are mounted with the possibility of reciprocating movement. In one of the plates 3, the recess 5 is made with inclined walls, and the length of the protrusion 4 exceeds the length of the protrusions of the other plates. The leash 7 is rigidly connected to the locking bar 6. The key 8 is made of two halves, the code holes 9 of which interact with opposite sides of the projections of the four plates and have two basic holes 12 for interacting with the stops 11 of the drum.

The cylinder lock mechanism works as follows.

For unlocking, the two halves of the key 8 are inserted into the cylinder mechanism before the contact of their base wells 12 with the stops 11 of the drum 2. The code hollows 9 of the key, interacting with the projections 4, move the plates 3 to the position in which their notches 5 are in line. Under the action of the spring, the locking bar will slide into the notches 5 of the plates and connect to the drum 2. When the drum is rotated beyond the protruding parts of the key 8 or beyond the protruding parts of the key gap frame, the leash 7 turns, unlocking the lock.

Locking is done in the same way. After pulling out both halves of the key 8, working on the long protrusion 4, the plate 3 is moved to any

the side which is a sloping wall of the depression pushes the blocking bar 6 from the hollows of the other plates, separating the drum from the leash. Under the action of an annular spiral spring, the plates 3 move, displacing their recesses relative to the locking bar.

On the inner side of the lid of the housing 1 there are radial grooves into which the locking bar is inserted as it leaves the recesses 5 of the plates 3, so that in the locked position of the lock the leash 7 is fixed against rotation.

The locking bar may have a curved shape that will change the key code. To increase the stroke of the plates 3, their ends are made with radius grooves corresponding to the diameter of the annular spiral spring.

A plate, the recess in which is made with inclined walls, is installed in the center of the package.

The plates 3 may be labeled with a recess displacement jaw, which facilitates assembly.

The design allows to reduce the axial size of the lock.
