FIELD OF THE INVENTION

products m

The aim of the invention is to improve the reliability of locking.

FIG. 1 shows a general view of the lock, in FIG. 2 - the same section {in FIG. 3 shows the node I in FIG. 2 (code sleeves).

The code lock includes a housing 1 with holes, a sliding 2 mounted on a sliding arm of a series of code rings 3 each of which has a groove C on the inner surface and an axial groove 5 communicating with it and clamps 6 located in the grooves of the code rings axial slots when unlocking the lock. The lock is equipped with a primary 7 and an additional

8 code bushings with control elements 9. Code bushings are installed inside the code rings with the possibility of rotation and axial movement. The clips 6 are made on the outer surface of the code sleeves. Grooves 10 and grooves 11 are provided in the holes of the housing 1 for accommodating code bushings. Code bushings 7 and 8 on the ends facing each other have interacting teeth 12 and are spring-loaded to fix their angular position. Items

When the code bushings rotate due to the presence of teeth 12 on their ends and springing in the axial direction, their angular positions are fixed.

To change the code, the retractable handle 2 is inserted into the housing 1 as far as it will go and remove its locking ring. Then the handle is removed from the housing and the code rings and bushings are swapped.

Claims (4)

1. A code lock, comprising a housing with holes, a retractable handle, mounted on a retractable handle, a series of code rings, each of which has a groove on the inner surface and an axial groove, which communicates with it, and clamps, which are located in their axial grooves when unlocking the lock, characterized in that, in order to increase the reliability of locking, it is provided with a code sleeve with a control element installed in the holes of the housing inside the code rings rotatably and axially displaced In this case, the latches are made in the form of protrusions placed on the outer surface of the code sleeve. 2 o The lock according to claim 1, characterized in that it is provided with an additional code sleeve with an element they are the protruding sections of code bushings protruding from the housing, control and locking devices in the form of protrusions The lock works as follows. To unlock the lock, control elements 9 install code sleeves on the outer surface installed inside the code rings coaxially with the main code sleeve, while on the end faces facing each other and 7 and 8 in numbers on the body in the half sleeves where their clamps 6, placed in the grooves 10 of the housing 1, are located opposite the slots 11. Then, the code discs 3 are installed / according to the code, while their axial grooves 45 5 are located opposite the clamps 6, placed in their grooves,. code bushings 7 and 8 are unlocked and the handle 2 can be pushed out of housing 1. For locking, the handle 2 is sunk into the housing and by turning the code rings 3 and control elements 9 block the code sleeves, locking the lock. 50 the teeth are interconnected, and the code sleeves are spring-loaded in the axial direction to fix their angular position. 3. Castle on PP. 1 and 2, which is based on the fact that grooves communicating with them are made in the holes in the housing to accommodate the lugs of the code sleeves, . 4. Castle on PP. 1 and 2, in that the control elements of the code bushings are sections of the code bushings protruding from the housing. on the outer surface installed inside the code rings coaxially with the main code sleeve, while on the facing ends of one of the code rings there are interactions the teeth are interconnected, and the code sleeves are spring-loaded in the axial direction to fix their angular position. 3. Castle on PP. 1 and 2, which is based on the fact that grooves communicating with them are made in the holes in the housing to accommodate the lugs of the code sleeves, .four. Castle on PP. 1 and 2, in that the control elements of the code bushings are sections of the code bushings protruding from the housing. 7 6 12 Editor M. Bandura Compiled by N. Kamsky Tehred L.
