Description

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

 The purpose of the invention is to increase the secrecy and reliability of the work.

 In FIG. 1 shows a cylinder lock mechanism in section; figure 2 tubular wrench; figure 3 is a view along arrow A in figure 2; figure 4 is a view along arrow B in figure 2; figure 5 separation washer; Fig.6 locking washer; 7, a transmitting element; on Fig section BB in figure 1 (position "Closed"); in FIG. 9 section DD in figure 1 (position "Closed"); in Fig.10 section BB in Fig. 1 (open position); in FIG. 11 section DD in figure 1 (position "Open"); in Fig.12 section GG in Fig.1 (position "Open").

 The cylinder lock mechanism consists of a housing 1 (Fig. 1) with a longitudinal groove 2 on the side surface. In the housing 1, with the possibility of angular movement, a locking cup 3 (Fig. 1) with a guide rod 4 for the tubular key 5 (Fig. 2) is installed. In the glass 3 without restriction of angular displacement, a set of locking discs 6 (Fig. 6) is installed in an amount of 5 pieces, each of which has a pin 7 (Fig. 1) that is pressed into a key hole 8 in the key hole (Fig. 6) for interaction with the corresponding code groove of the tubular key 5. Between the locking discs 6 there are fixed dividing washers 9 having a protrusion 10 on the outer surface. The transmission element 11 (Fig. 7) with a pressed pin 12 (Fig. 1), which forms two protrusions, the first protrusion 13 (Fig. 7) in the key hole for engaging with the restrictive groove 14 (Fig. 2) is installed last in the glass 3. ) a tubular key 5, and the second protrusion 15 (Fig. 7) on the outer surface is designed for fixed connection with the glass 3. To prevent spontaneous rotation of the locking discs 6, a spring washer 16 is installed in the glass 3 (Fig. 1).

 On the outer surface of the disks 6 and washers 9, recesses 17 (Fig. 5, Fig. 6) are made for partial placement of the fixing pin 18 (Fig. 1) during unlocking. In the glass 3, two slots are made in the diametrical direction, in which the protrusions 10 of the separating washer 9 and the protrusion 15 of the transmission element 11 are placed on one side and the fixing pin 18 on the other. The longitudinal groove (Fig. 9) of the housing 1 is intended for partial placement in it the fixing pin 18 in the closed position and the spring-loaded ball of the retainer 19 (figure 1). The axial movement of the glass 3 relative to the housing 1 is limited by the retaining ring 20 (figure 1). The leash 21 (Fig. 1) of the locking cup 3 is kinematically connected with the lock mechanisms (not shown). The lock is unlocked with a tubular key 5 (Fig. 2) having a longitudinal groove 22 (Fig. 3) on the outer surface for receiving the protrusions 8 of the locking disc 6 and the protrusion 13 of the transmitting element 11 when the tubular key 5 is inserted into the lock. In addition, on the outer surface of the key 5, perpendicular to the longitudinal groove 22, code grooves 23 are made (FIG. 2) of a L-shape for interaction with the corresponding protrusions 8 of the locking discs 6. A restrictive groove 14 is also made on the key 5 (FIG. 2, FIG. 4) L-shaped, designed to limit the angular movement of the locking discs when dialing the code by interacting with the protrusion 13 of the transmitting element 11. To fix the locking cup 3 when removing the key 5, a spring-loaded ball-lock 19 (figure 1).

 The castle operates as follows.

 In the closed position, the protrusions 8 of the locking discs 6 and the protrusion 13 of the transmitting element 11 are located on the same line, and the locking pin 18 is located in the slot of the locking cup 3 and partially in the longitudinal groove 2 of the housing 1.

 To unlock the lock, the longitudinal groove 22 of the tubular key 5 is aligned with the protrusion 13 of the transmitting element 11 and the key 5 is inserted into the holes of the element 11 and discs 6 against the stop surface E of the restrictive groove 14 into the protrusion 13 of the transmitting element 11. Then, turn the key 5 counterclockwise to the stop surface F of the restrictive groove 14 into the protrusion 13 of the transmitting element 11. When turning the key 5, the side surfaces G of the code grooves 23 of the key 5 mesh with the protrusions 8 of the locking discs 6 and rotate them at a certain angle. The recesses 17 of the disks 6 are aligned in a line opposite the fixing pin 18 and form a groove for it. Then, the key 5 is pushed deep into the lock against the stop surface H of the restrictive groove 14 into the protrusion 13 of the transmitting element 11. In this position, the locking cup 3 by means of the protrusions 13 and 15 of the transmitting element 11 is rigidly connected to the key 5. When the glass 3 is further rotated by the key 5, the fixing pin 18 moves from the groove 2 of the housing 1 into the groove formed by the recesses 17 of the locking discs 6, and thereby disengages the cup 3 with the lead 21 from the housing 1 and allows you to rotate both clockwise and counterclockwise, thereby unlocking Whether locking the lock.

 To remove the key 5, it is necessary to pull the key 5 towards you as far as it will go, turn the locking cup 3 with the key 5 in any direction until the spring-loaded locking ball 19 drops into the groove 2 of the housing 1, then turn the key 5 clockwise to the stop and remove it from the lock.

 The introduction of a restrictive groove on the periphery of the tubular key allows you to increase the maximum code angle, and this in turn will increase the number of code combinations without increasing the number of locking discs.

 The implementation of the restrictive and code grooves of the L-shaped form on the key allows the lock bolt to be moved when opening and closing by means of two-sided rotation of the locking cup with a pipe wrench.
