SU1615300A1 - Cylindrical mechanism of lock - Google Patents

Abstract

The invention relates to staples and makes it possible to increase the reliability of locking and to simplify the design of the cylinder lock mechanism. In case 1, outer 2 and inner 3 cores are installed, blocked by spring-loaded locking pins 6 and pushers 7. Outer core 2 is connected with a lead 8, and inner core 3 is connected with an additional lead 11. Recesses 5 are aligned in the cores from the inner end, coaxially with cores for insertion of the insert 9, the ends of which 10 serve as a stop for the key 4. 2 Il.

The invention relates to staples m.

The purpose of the invention is to improve the reliability of the lock and simplify the design.

Figure 1 shows a cylinder mechanism; a slit; figure 2 - section aa on

1FIG.1.

The cylinder lock mechanism includes a housing 1 with longitudinal and radial holes, installed in the longitudinal hole of the housing outer 2 and inner 3 cores, each of which has openings coaxially with the radial holes of the housing, a turnkey 4 well and a recess made from the inner end 5, jCOOCHoe with a core, spring-loaded I locking pins 6 and pushers 7 placed respectively in the radial holes of the housing and the cores, the lead 8 connected to one of the cores, the shell 9 placed in the recesses of the heart Receivers with the possibility of longitudinal movement and interaction with one end of the key when unlocking from the outside, and an abutment pad 10 for limiting the key travel when it is inserted into the housing. The mechanism is provided with an additional leash 11 associated with another core. The insert 9 is made in the form of a cylindrical rod and is installed with the possibility of rotation and interaction with the key with another end when unlocking from the inside. The thrust pad 10 for the key is formed by the ends of the insert 9.

The lock works as follows.

When unlocking the keyhole 4 from the outside into the support pad 10, a key 4 is inserted which moves the insert 9 in the recess 5 and is set in a position in which the ends of the locking pins 6 and the pushers 7 move along the connector line of the housing 1 and the outer core 2 to unlock core. When the key is rotated, the core 2 and the leash 8 associated with it rotate, unlocking the lock.

When unlocked from the inside, the key 4 is inserted into the keyhole of the inner core 3, while it interacts with the opposite end of the insert 9,

putting it all the way into the recess 5 of the outer core 2. When the key is turned, the unlocked inner core rotates, and with it the additional leash 11 unlocking the lock.

Locking is done in the same way.

By installing liners of various lengths into the cylinder mechanism, it is possible to switch to additional keys with different

tail length.
