Description

The invention relates to staples, namely, lock locks, which can be used to seal doors of various rooms.

Limes are a temporal lock, contents and a casing with a rotatable pull-out handle and guides installed in the casing guides for interacting with the ends of the camshaft shut-off locks, which have opposite walls of the nest, the axes of which coincide with the longitudinal axis of the lock and spring-loaded helical spring located at its ends in the sockets .x, wherein each zaorny plate is provided with a hook, and a cylinder mechanism placed in the housing, having a leash for interacting with the hooks of the locking bars 1.

The disadvantage of this lock is its low reliability, the loss of spring stability during compression.

The purpose of the invention is to improve the reliability of the lock in operation.

The goal is achieved by the fact that the lock hangs, containing a housing with tilt-and-out handle and guides, mounted in guide housings for cooperation with the ends of the arms of the locking plates having opposite slots on the opposite walls, the axes of which coincide with the longitudinal axis of the lock , and spring loaded by a spiral spring located at its ends in the sockets, each locking bar provided with a hook, and a cylinder mechanism placed in the body, having a leash for interacting with the locking bars of the locking bars . the hooks are made in the form of L-shaped protrusions located on the opposite steppes of the slats on opposite sides From the lock axis of the lock, while the flanges of the ledges are directed to the opposite sides of the lock longitudinal axis.

FIG. 1 shows the lock in the closed position, a longitudinal section; in fig. 2 - section A - A in FIG. one; in fig. 3 - lock with key unlocking, longitudinal section; in fig. 4 - section B - B in FIG. 3; in fig. 5 - lock in open position, longitudinal section; in fig. 6 shows section B - B in FIG. five; in fig. 7 - section G-Y in FIG. five; in fig. 8 is a section d-d in FIG. 6

The new lock (Fig. 1) includes a housing 1, a shackle 2, one end of which is spring-loaded with a spring 3, and the other is made with a bevel 4, and a cylinder mechanism 5 with a driver made in the form of a fork 6. At the ends of the shackle 2, notches 7 and 8 under the locking strips 9 and 10, which are located in the cavity 11 of the assembly guide plate 12 and are spring loaded between

a spiral spring 13. The ends of the spring 13 are clamped in the slots 14 and 15, Iss. at the ends of 16 and 17, the planks 9 and 10, and the ends of the arms 2 are located in the through holes 18 and 19, made in the plate 12 and connected to the cavity 11. The spring-loaded end of the arms 2 has a protrusion 20, the diameter of which is larger than the diameter of the hole 18. Locking strips 9 and 10 have

hooks 21 and 22, pulled out in the form of L-shaped projections, located on the opposite walls of the slats on opposite sides of the longitudinal axis of the lock, shelves 23 and 24 of the projections 21 and 22 are directed opposite to the longitudinal axis

the castle.

The teeth 25 and 26 forks 6 are located in the slots formed by L-shaped protrusions.

The lock works as follows.

In the locked position of the lock (Fig. 1), the locking strips 9 and 10 are inserted into the recesses 7 and 8 of the arms 2, and the tooth 25 and 26 of the fork 6 (Fig. 2) are non-contact located at the shelves 23 and 24 of the L-shaped projections 21 and 22 on bars 9 and 10.

In the case of unlocking the locked lock with a key (Fig. 3), the cylinder 5 of the mechanism 5 is rotated, and with it the forks 6. With the teeth of 25 and 26, the forks 6 act on the shelves 23 and 24 of the projections 21 and 22 of the locking bars 9 and 10 and swing them to each other before exiting the recesses 8 and 7 of the arms 2, while compressing the spring 13 (Fig. 4).

After the release of the locking bar 9 and 10

From the recesses 7 and 8, the bow 2 is removed from the lock KO Miyca 1 under the action of the spring 3 (Fig. 5).

In the open position of the lock (Fig. 5), one end of the handle 2 is pressed by the spring 3 to the plate 12 and contacts it with the help of the protrusion 20, and the other end of the handle is pulled out of the housing I. The lock strip 9 is pressed by the spring 13 to the bow located in the housing 1 2, and the end of the label

10 is located in the aperture 19 of the plate 12, while the forks 25 and 26 of the plug are non-contact located at the shelves 23 and 24 of the digging plates (Fig. 6).

With the automatic locking of the lock, the extended end of the bow 2 is guided into the hole 19 of the plate 10. A bevel 4 of the indicated end of the bow acts on the locking nlan 10 and thereby moves it along the cavity 11 of the plate 12, compressing the spring 13. When the notches 7 and 8 of the bow align with strips 9 and 10 in the holes 18 and 19, the spring 13 pushes the locking strips 9 and 10 until they enter the recesses 7 and 8 and thereby provides automatic locking of the latch.

Then the key is unlocked again.
