Abstract

The invention relates to locking devices, namely to door locks, and allows to increase the reliability of locking the door. On the lower base of the body there is a hinge, which, when the door is closed with a lock, covers the protruding part of the door lining fixed to the doorway. The bolt is provided with a protrusion and is spring-loaded in the direction of the door lining, in which a hole is made and a socket for a bolt and a bolt is connected to it. The door lining has a box-like shape, with the hole with the socket slotted on one of the faces, and on its adjacent face there is a slotted slot connected to the hole to allow the bolt to move. The door trim is set in such a way that the face of the latch opposite the face hole. 4 il.

Description

This invention relates to electronic devices, and in particular to door locks.

The purpose of the invention is the reliability of locking.

Figure 1 shows the proposed castle, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1 (the position is closed); figure 4 - section bb in figure 1 (the position is Open).

The lock includes a housing 1 with a keyhole 2, in which a spring-loaded bolt 3 is located. The housing 1 is made such that its lower base forms a loop 4, which in the closed position covers the projecting portion 5 of the box-shaped door lining 6 on the doorway.

On the crossbar 3, a protrusion is formed, formed by a transverse pin 7. On one of the edges of the door lining, a hole 8 is made and the socket 9 communicates with it to enter and place the crossbar with a protrusion. On the adjacent face there is a longitudinal groove 10 for providing the movement of the bolt.

The lock works as follows.

When the door is closed, the hinge 4, which is made on the lower base of the housing 1, covers the protruding part 5 of the door trim 6 on the doorway.

The bolt 3 is made so that when the door is closed on the lock, it engages in the lock case 1, and the transverse pin 7, which is located on the dead bolt 3, engages with the figured groove formed in the door lining by the hole 8 and the socket 9.

Dp in order to open the lock, you need to bolt 3 to push out of the box 4480202

lock 1, while the transverse pin 7 at the end of the stroke bolt 3 will be released from engagement with the groove of the door lining attached to the frame of the door opening 5.

Thus, there are two locks in the lock at the same time. On the one hand, loop 4, made on the lower base of the lock case, prevents the door from opening using simple devices, i.e. It is not possible to push the door and the doorway, but on the other hand pin 7 bolt 3 is also a locking device for the closed door: it engages with the figured groove of the door lining, thereby preventing the door from opening from the outside.
