Description

 The invention relates to number locks and can be used, for example, in safes, in iron household and secret production doors.

 Known code number lock containing a fixed and movable housing, a movable ring, separated by smaller rings, a reading mechanism.

 The well-known castle is unreliable in operation and does not provide sufficient secrecy.

 The invention achieves the technical result - increasing the secrecy and reliability of the castle.

 This technical result is achieved by the fact that in the coded number lock containing the movable housing fixed by it, the movable rings separated by smaller rings, the reading mechanism according to the invention, the movable and fixed housing are connected by balls, a diametrical protrusion having a slot is made inside the stationary part of the housing, which has a movable comb, and on the outer diameter of the protrusion there are movable rings separated by smaller rings, while the carrier is fixed to the movable housing etal counting mechanism comprising a drum consisting of several disk and ratchet mechanism for rotating the drum at a desired angle.

 In FIG. 1 shows a general view of the proposed castle; in FIG. 2 is a section AA in FIG. one; in FIG. 3 - section BB in FIG. 2; in FIG. 4 - ratchet mechanism; in FIG. 5 - shaped part 17; in FIG. 6 is a view of the end face of the movable housing with numbers.

 The lock contains a fixed housing 1 with time divisions, which is attached to the doors of various objects (safes, doors, especially metal ones), a movable housing 2, rigidly screwed to the last part 3, a restrictive ring 4, a shaft 5, a fixing ring 6, balls 7, s by means of which the movable housing 2 is connected to the stationary housing 1, the intermediate ring 8, the spring 10, part 10, the readout disc 11 located on the diametrical protrusion, the movable rings 13 located inside the stationary part of the housing, separated by a smaller and rings 12 mounted motionless by means of specially made semicircular protrusions included in the semicircular groove, while the diametrical protrusion of the fixed part of the body has a slot in which there is a movable comb 14 mounted on the diametrical protrusion of the fixed part of the body in the slot 15 made therein, a shaped part 17 located in the housing spring-loaded by spring 16, a spring-loaded stop 18, consisting of separate disks on a common key 19, a drum 20, a spring-loaded part 21, a part 22, screwed to the housing 2, the bearing part 27, on the upper side of which there is a ratchet mechanism, including parts 23 and 24, a screw 25, a ratchet 26.

 The number is dialed by turning the movable housing relatively stationary.

 The fixed part is attached to the object, safe, door, etc., especially to metal doors, where access is not available to strangers due to privacy. The housing also has a centering bend as well as mounting holes.

 Inside the fixed part of the housing (Fig. 1) there is a diametrical protrusion, which, in turn, has a slot in which the movable comb 14 is mounted (Fig. 3). On the outer diameter of this protrusion there are movable rings 13Y, separated by smaller rings 12, which are stationary in their places due to specially made semicircular protrusions inside the semicircular groove. In the lower part of the housing where the shaped part 17 is placed with the spring 16 acting on the stop 18, there is also a milling where the stop 18 with the spring 19 is placed (Fig. 5).

 On the fixed part of the housing 1 is fixedly fixed mounting ring 6. which holds the movable comb 14.

 The movable part of the housing 1 is easily rotated on the balls 7 relative to the stationary part of the housing.

 The ring fixed with screws is rigidly fixed in the ring. There is a slot in which part 10 (Fig. 3) enters, spring-loaded by spring 9.

 On the movable housing 2 (Fig. 4), the carrier part 27 is rigidly screwed onto which a reference mechanism is installed, including a drum 20, consisting of separate disks on a common key 19. Part 22 moves the rings 13 and 12 depending on the drum 20, the part 22 is spring loaded part 21. On the upper side of the carrier part 27 there are parts 26, 23 and 24, helping the operation of the rotation mechanism. The ratchet 26, when turning, hits the stop 18 (Fig. 5) and rotates the drum to the desired angle.

 When turning from the reference risks on the part of the housing 1, all the numbers make up a secret number. Comb 14 aligns the rings by spring force. Thus, it turns off the rotation system and includes parts that push or pull the bolts, locks, deadbolts and all sorts of devices.

Claims (1)

 A code number lock comprising a fixed and movable housing, movable rings separated by smaller rings, a reading mechanism, characterized in that the stationary and movable housings are connected by balls, a diametrical protrusion having a slot in which the movable comb is located inside the stationary part of the housing, and on the outer diameter of the protrusion there are movable rings, separated by smaller rings, while on the movable case a supporting part is fixed with a reference mechanism, including a drum consisting of several discs, and a ratchet mechanism for turning the drum to the desired angle.
