Abstract

The invention relates to staples and makes it possible to increase the reliability of locking and to reduce the metal intensity of a combination lock. In the housing 1, a sliding arm 2 is placed on which spring-loaded bushings 6 are mounted with the possibility of rotation and axial movement with protrusions 7 on the outer surfaces and teeth 8 at the ends for fixing their angular position. On the sleeves 6, 7, code rings 3 are installed with grooves 4 and axial grooves 5 for accommodating protrusions 7 of the sleeves. In the grooves of the 4 code rings, stops 9 are fixed to interact with the protrusions 7 when dialing the code. 3 il.

Description

FIG. 2

The invention relates to staples m.

The aim of the invention is to improve the reliability of locking and reducing metal consumption.

FIG. 1 shows the castle, a general view; in fig. 2 - the same section; in fig. 3 - code sleeves.

The code lock comprises a housing 1 with holes, a retractable handle 2 and mounted on a retractable handle a series of code rings 3, each of which has a groove 4 on the inner surface and an axial groove 5 communicating with it. In the code rings 3 there are bushings 6 with protrusions 7 on the outer surface, located in the grooves of 4 code rings with the possibility of placement in the axial grooves 5 when unlocking the lock. The sleeves 7 on the ends facing each other have interacting teeth 8 and are spring-loaded in the axial direction. The lock is equipped with elements 9 of the control sleeves 7, made in the form of 3 stops attached to the grooves of the code rings 3, which interact with the projections of the sleeves.

The lock works as follows.

To unlock the lock, each code ring 3 is turned first in one direction according to the code, the stops 9, interacting with the protrusions of the 6 sleeves, set them in a certain position. Then the code ring is turned in the opposite direction according to the code, the axial groove 5 is located opposite the protrusion 7, the release blocking of the sleeve 6. Then the bow 2 is pushed out of the housing 1, the protrusions 7 exit the grooves 4 and enter the axial grooves 5. The lock is unlocked.

For locking, the handle 2 is sunk into the body and by turning the code rings first in one direction, and then in the other one knocks the lock code.

When the sleeves 6 rotate due to the presence of teeth 8 on their ends, their angular positions are fixed.

To change the code, the retractable handle 2 is sunk into the body as far as it will go and its locking ring is removed. Then the handle is removed from the housing and the code rings and bushings are swapped. A change can be made only after the installation of the current code.

Controlling the hubs via code rings increases the security of the lock.

Claims (1)

Invention Formula A combination lock, comprising a housing, a retractable arch mounted on the stand, a sliding arch of code rings, each of which has a groove on the inner surface and an axial groove communicating with it, and housed inside the code rings can be rotated and axially moved. , protrusions on the outer surface, located in the grooves of the code rings with the possibility of placement in their axial grooves, and teeth, made on facing each other for fixing the angular position of the sleeves, that, in order to increase the reliability of locking and reduce metal consumption, the control elements of the bushings are made in the form of stops fixed in the grooves of the code rings for interaction with the protrusions of the sleeves, while the number of sleeves corresponds to the number of code rings.
