The technical field to which the nolose model belongs.

The inventive utility model relates to locking devices, in particular, to cylinder mechanisms that can be used in various designs of locks.

The prior art.

Of the known cylinder mechanisms, the closest in technical essence to a utility model is

“The cylinder lock mechanism according to certificate No. 16754, RF, MKI E 05 B 27/06, 2000, comprising a housing with an axial channel, two rotary cores secured in the housing with lock washers, with radially spaced spring elements in the form of rectangular frames, an annular lead located in the middle part of the body, and shaped spring-loaded clamps-clamps located in the end part of each rotary core.

The common features of this lock with the claimed technical solution are two rotary cores secured in the housing by lock washers, with radially arranged elements in the form of rectangular frames, and an annular leash located in the middle of the housing at the ends of the rotary cores.

MNC E 05 V 27/06

This cylinder lock mechanism has low reliability due to the fact that it: there is no protection of the cores from drilling code frames; there is the possibility of criminal manipulations with clamp brackets through the key channel for the purpose of unauthorized (without a key) turning the ring leash and, accordingly, opening the lock or setting it in a position that prevents the key from being inserted; there is the possibility of visual observation through the key channel into the protected area,

The essence of a useful model.

The problem to which the proposed technical solution is directed is to increase the reliability of the cylinder mechanism. To solve this problem, signs have been introduced into the device to prevent unauthorized access to the components of the lock, namely: in the proposed cylinder lock mechanism containing a housing with an axial channel, two rotary cores fixed in the housing by lock washers, inserts fixed in the rotary cores are introduced with code elements freely placed in them, and retainer plates installed in key channels, and a spring interacting with the ball is installed in each retainer plate com

The utility model allows to increase the reliability of the cylinder mechanism of the lock due to the exclusion of unauthorized access to its components by placing plate fixators with linear displacement locks in key channels. And the placement between the end surfaces of the rotary cores and the body of heat-treated washers and in the rotary cores - heat-treated pins allows you to enhance the technical result achieved by eliminating the possibility of criminal manipulations with the elements of the lock.

The list of figures of drawings Figure 1 shows the device of the cylinder mechanism of the lock; on the

figure 2 is a section aa in figure 1, figure 3 is a section bb in figure 1.

Information confirming the feasibility of the useless

The cylinder lock mechanism consists of a housing 1, in which

with the possibility of rotation about its axis, two rotary cores 2 and 3 are installed, between the end surfaces of which and the housing 1 there are heat-treated washers 4. In the rotary cores 2 and 3 with a key turnkey channel 1, heat-treated pins 7 and inserts 5 and 6 are freely placed them with code elements 8. The rotary cores 2 and 3 are fixed in the housing 1 by lock washers 9. In the key channels of the rotary cores 2 and 3 there are two locking plates 10 and I, interacting with each other and with the ring a lead 12, freely mounted on the rotary cores 2 and 3. In the latching plates 10 and 11 are placed linear displacement clamps, made, for example, in the form of balls 13 and springs 14.

models. , The cylinder lock mechanism operates as follows. To unlock the key 15 is inserted into the key channel of the rotary core 2 or 3 and the liner 5 or 6 until it stops. In this case, the end surface of the key 15 moves the locking plate 10 or 11 into the groove of the annular lead 12 to the position where the ball 13 fixes it under the action of the spring 14, and the code grooves of the key 15 move the code elements 8 to the position at which their ends are placed along the connector line of the housing 1 and the liner 5 or 6 and the rotary core 2 or 3, forming a cylinder. Then the key 15, and with it the annular leash 12 is rotated, unlocking the lock.

Claims (1)

A cylinder lock mechanism comprising a housing with an axial channel, two rotary cores, an annular lead located in the middle of the housing, code elements, characterized in that the rotary cores are provided with inserts for code elements, and fixing plates are installed in the key channels and in the annular lead in which the linear displacement clamps are placed, made, for example, in the form of balls interacting with the springs.
