Figure 1 - shows a General view of the castle level; figure 2 is a section aa of figure 1; figure 3 - shows a General view of the cover of the level lock.

The level lock contains, the housing 1 (see figure 1), the cover 2, the holes for the key lock 3, 19, the grooves 4, 15, the fasteners 5, 6, 8, 9, the lock 7, the bolt 10,

the inner cavity 11, the rack 12, the levers 13, the guides 14, the holes 16, 17, 20, the springs 18, the through holes 21 and the secret hole 22.

The housing 1 (see Fig. 1) is made of steel sheet material, mainly by stamping, and is a part or assembly unit, mainly of a box shape. The cover 2 is made in the form of a metal plate of arbitrary geometric shape in plan and section. In the housing 1 and in the cover holes are made for the key lock 3, 19, respectively. On the peripheral sections of the cover 2, grooves 4 are made, which are necessary for securing the lock to the supporting surface. The lock contains fasteners 5, 6, 8, 9 by means of which the cover 2 is fixed to the housing 1. The latch 7 is fixed to the cover 2 and interacts with the end parts of the springs 18. The crossbar 10 contains a head and a shank and is installed with the possibility of authorized movement relative to the housing in guides (in Fig. 1 conditionally pos. not indicated) and communicated with the secrecy mechanism through the shank. The housing 1 has an internal cavity 11. The posts 12 are located in the internal cavity 11, are fixed to the housing 1 and have threaded holes for fasteners 5, 6, 8, 9. The levers 13 (see figure 2) are made of steel sheet material and placed on the guides 14 with limited movement, and the guides 14 are mounted on the cover 2. On the guides 14 there are made through holes 21 (see FIG. 3) and flanges (flanges), the end parts of which interact with the end parts of the uprights 12, and the through holes 21 combined with threaded holes racks 12. On the levers 13 grooves 15 and holes 20 are made, through which the levers 13 interact with the guides 14 and their limited movement (limited movement is provided by the length of the holes 20). Holes 16.17 are made on the cover 2 and are intended for input of fasteners 5.6 into them. Each leveler 13 is spring-loaded by means of springs 18, and one end part of the springs is fixed to the levers 13, and the other interacts with the latch 7. Each levee 13 contains a secret hole 22, the surface of which is formed by cavities and protrusions. The security mechanism of the lock is formed by the levers 13, the springs 18, the guides 14 with through holes 21, the retainer 7, the grooves 15, the holes 20 and the secret holes 22. The security mechanism is mounted on the cover 2 of the level lock. The holes for the key lock 3.19 are combined and designed to enter the key into interaction with the security mechanism of the lock.

The castle operates as follows.

Insert the key into the hole for the key 3 or 19 and, due to its rotation, move the dead bolt 10 away from the housing 1 or towards the housing 1 (the direction of movement in Fig. 1 is shown by arrows). As a result of the rotation of the lock key, the lock key acts simultaneously on both the levers 13 and the shank of the crossbar 10, and the levers 13 make spring movements relative to the guides 14, and each levers 13 makes such movements by a certain amount.

The cover of the level lock contains grooves 4 (see FIG. 3), holes 16, 17, an opening for the key lock 19, the security mechanism of the level lock being fixed to the cover, and on the side facing the inner cavity 11 of the lock body 1. Mechanism the security of the lock is formed by the levers 13, the springs 18, the guides 14 with through holes 21, the lock 7, the grooves 15, the holes 20 and the secret holes 22. The operation of the privacy mechanism of the level type is described above.

Thus, the claimed technical solutions ensure the achievement of the task and obtaining a new technical result. As a result of the proposed design of the lever lock and the cover of the lever lock, a simple and quick replacement of the privacy mechanism in domestic conditions is achieved, which is realized by removing the lock cover together with the privacy mechanism, which is possible after unscrewing the fasteners 5, 6, 8, 9.
