Description

The invention relates to locking mechanisms and can be used in the structures of mortise, push and locking locks. ,

Known fur locks are known: the lower part of the lock contains a housing in which a rotatable cylindrical core is disposed with pushers arranged therein interacting with locking pins installed in the housing and a press key f-l.

The disadvantage of this device is low secrecy, which is due to the use of movable cylindrical pins as a quality. pushers.

The purpose of the invention is to increase the secrecy of the mechanism.

The goal is achieved by the fact that in the locking mechanism of the lock, which includes a housing in which a rotatable cylindrical core is located with thrusters located in it, interacting with locking pins installed in and a push key, the core has sector notches, and the plungers are made in section in the form of sectors, are truncated and placed in the sector recesses of the core, while on the surface of the core there are transverse grooves in which the locking pins are placed, and on the surface of each pusher in The working and false grooves for locking pins are made perpendicular to its longitudinal axis.

FIG. 1 shows the locking mechanism, a section; FIG. 2 - the core of the mechanism; in fig. 3 - pusher locking mechanism; figure 4-. push key.

The device includes a housing 1, in which radially arranged locking cylindrical pins 2 are pressed, as well as a guide lock pin 3, a rotatable cylindrical core 4 and pushers 5, 2Q spring-loaded relative to the core with cylindrical springings, a leash 7 for engagement with the locking organon of the lock (not shown ) and kr. 8, 1, 1% 1 case body 1 from the side of the lock. The core 4 has sector notches, on its surface there are made longitudinal grooves 9 for mounting and dismounting the core and transverse grooves 10, in which the locking pins 2 are replaced, which: allows the core to rotate relative to the body. The grooves are the same with each other and have widths - d of the pin 2 + 0.5 mm, in depth - more than the protruding part of the pin 2 by 0.5 mm.

The pusher 5 ispeet on the surface of the working groove 11, connecting two planes lying at an angle of 90 ° and false hollow grooves. The distance between the working groove and the false grooves is the same. In addition, the width and depth cannot distinguish the working | groove from the false. Each pusher has a blind hole 13 for the springs 6. The press key of the locking mechanism consists of a body 14 in which a tongue 15 is made to orient the key in the locking mechanism, an annular groove 16 which serves as a stop for the pins 17 and simultaneously prevents the key from pulling out in the working position springs 6.

The device works as follows.

When the press key is inserted into the opening of the body of the locking mechanism, the guide locking pin 3 enters the key body groove 15 of the key 14, orienting the position of the push button relative to the body. The pins 17 of the key are pressed at a predetermined distance by the pushers 5, aligning the axes of the working grooves 11 in one plane coinciding with the plane in which the axes of the pins 2 are located. This position is determined by abutting the end surface of the key into the core 4. Then the key can be rotated with the rotary drum in any direction on. Moreover, removing the key from the locking mechanism when turning less than 36 ° O does not allow the guide locking pin 3 falling when the key is turned at the initial moment into the annular groove 16. The angular displacement of the rotary drum is transmitted to the lock mechanism of the leash 7. When you press all the tappets The axes of the pins 2 should rest against the core and coincide with the plane in which the axes closest to the key of the slots (working or false) of the locking elements will appear. In the absence of contact of the pins 17 of the key with the pushers 5, the latter are fixed from the angular displacement with the pins 2 abutting in a plane lying at an angle

 locking elements.

The use of the proposed device in comparison with the known gly can significantly increase the degree of secrecy of the lock.

The length of the pushers, their number, the number of false grooves on each element is determined by the purpose of the lock.

The secrecy of the locking mechanism is determined by the number of pushers and the number of grooves on each of them.

Increased secrecy - by increasing the number of pushers, does not lead to an increase in the length of the locking

mechanism.

The introduction of false grooves that have the same parameters as the working groove does not allow the position of the working groove to be determined when the lock is unlocked using the LIST number.
