Abstract

1, the invention relates to brackets — HbB-i of the production unit. The chain of the invention is to simplify the construction of the locks. In case 1, a clip 4 with a groove 5 is freely installed. PPZ 5 is made along a helix. The cage contains locking discs 7 with shaped openings 8 on a turn-key 2, recesses 11 and radial protrusions 9 for engagement with the side ps of the upper 10 slots. The housing 1 is equipped with a locking pin 6 with the possibility of placing it in the holes 11 of the locking disks 7. The mechanism is equipped with a laptop, on the rod of which a screw pin is made with a pitch equal to the helix of the groove 5 of the yoke 4. 4 Il.

The purpose of the invention is to improve the manufacturability.

Figure 1 shows the cylinder disc lock mechanism (part of the locking disc is not shown), a general view; figure 2 is a view of And figure 1; on fig.Z - view B in figure 1; figure 4 - the same, when you turn the key on the magnitude of the working stroke.

Cylinder disc lock mechanism Contains case 1 with groove 5 made in it under locking pin 6. Case 1 has a holder 4 with a through groove made in it under the locking pin 6, spring-loaded relative to the holder. In the holder 4, a groove with side surfaces 10 is also made, and the groove is made in such a way that the surfaces 10 of the disk mechanism form a helix. In the holder 4, locking discs 7 are provided with recesses I1 provided thereon for locking pin 6, radial protrusions 9 and center holes 8, the angle y between the center hole profile 8 and the radial protrusion 9 for each locking disc 7 having the same value.

There is a key 2 for unlocking the cylinder disc mechanism, which contains a rod with a longitudinal helical screw 3 on it.

The mechanism works as follows.

When the key is inserted into the cylinder disc mechanism, the rod alternately enters the center openings .8 of the locking discs 7, and the key is rotated, in this case counterclockwise, until

the code of this cylinder mechanism, which ensures the alignment of the recesses of the 11 locking discs along the line of the through groove in the holder 4 and the insertion of the fixing pin 6 into the recesses. The yoke 4 is freely rotated in the housing I by radial protrusions 9 interacting with the surface 10 of the groove 5 in the yoke. Further turning with the key of the yoke 4 relative to the body 1 occurs without limitation in angle to the required number of revolutions, due to the design of the lock.

The cycle of operation is repeated.

The cylinder disc lock mechanism is easy to implement because sampling the helix cage with a pitch equal to the pitch of the screw key face reduces the range of locking discs and dies for their manufacture, since all locking discs are made with the same angle between the profile a center hole and a radial protrusion; in this case, the center holes mate with the longitudinal helical tong key in the mechanism at any permutation of the locking discs in the cage.
