Non-spoon high-strength mechanical cipher lock with large cryptograph content

Abstract

The present invention discloses a key-free high strength mechanical cipher lock with large cipher content, comprising a lock body, a lock core arranged inside the lock body, as well as cipher setting devices, wherein the lock body comprises a lock liner tube body, as well as a lock liner front cap and a lock liner back cap which are fixed with the lock liner tube body; the lock core comprises a lock core rotating shaft, as well as an eccentric wheel and a positioning wheel which are fixed on the lock core rotating shaft; the lock core also comprises a lock bolt moving in straight line; the lock liner front cap is provided with N cipher pairing wheel shaft holes distributed around a lock core shaft hole; N cipher setting devices are provided, and N is more than or equal to 1; each cipher setting device comprises a cipher pairing shaft, as well as a cipher pairing wheel and a positioning wheel which are fixed on the cipher pairing shaft; M positioning holes distributed around the cipherpairing wheel shaft holes are arranged on each positioning wheel; the distance between the centers of the lock core shaft hole and the cipher pairing wheel shaft holes is less than the radius sum of the positioning wheel and a cipher adjusting wheel; the position in the cipher adjusting wheel, which interferes with the positioning wheel is cut away to form an unfilled corner. The key-free high strength mechanical cipher lock is suitable to be used as the door lock of various safety boxes, warehouses, companies and residential houses.

Description

technical field [0001] The invention relates to a coded lock, in particular to a keyless high-strength mechanical coded lock with large code content. Background technique [0002] In the combination lock in the prior art, the rotating part has a convex handle that is easy to grasp, and the rotating disc on the rotating shaft extending from the rotating part has only one groove, and the rotating disc is only fixed by setting the pin shaft at the front end of the rotating shaft. The combination lock of this structure It is not strong enough, and it is easy to grasp the convex handle with ordinary common equipment, and the lock cylinder mechanism can be pulled out as long as it is pulled outward slightly, which is very unsafe. In the process, once the predetermined unlocking position is encountered, that is, when the single groove on the turntable aligns with the lock bolt, there will be a weak sound, and this sound is easy to distinguish for experienced people, and the passwor...

[0002] In the combination lock in the prior art, the rotating part has a convex handle that is easy to grasp, and the rotating disc on the rotating shaft extending from the rotating part has only one groove, and the rotating disc is only fixed by setting the pin shaft at the front end of the rotating shaft. The combination lock of this structure It is not strong enough, and it is easy to grasp the convex handle with ordinary common equipment, and the lock cylinder mechanism can be pulled out as long as it is pulled outward slightly, which is very unsafe. In the process, once the predetermined unlocking position is encountered, that is, when the single groove on the turntable aligns with the lock bolt, there will be a weak sound, and this sound is easy to distinguish for experienced people, and the password can be set The lock is opened, the safety performance is poor, and the number of passwords formed by each password setting device is not enough, which is easy to crack
