Description

technical field [0001] The invention belongs to the technical field of combination locks, and relates to a bounce-type mechanical combination anti-theft lock. Background technique [0002] In the prior art, combination locks generally have electronic combination locks and mechanical combination locks. Since electronic combination locks require power and passwords are easily scanned and cracked, their application is greatly limited. [0003] Existing mechanical combination locks generally include two forms: turntable combination locks and push button combination locks. The turntable combination password input is complicated and difficult to operate. It requires precise alignment when inputting, and the password needs to be manually destroyed after unlocking, which takes time to unlock. Longer, usually more than half a minute, so use less.

[0002] In the prior art, combination locks generally have electronic combination locks and mechanical combination locks. Since electronic combination locks require power and the passwords are easily scanned and cracked, their application is greatly limited.

[0003] Existing mechanical combination locks generally include two forms: turntable combination locks and push button combination locks. The turntable combination password input is complicated and difficult to operate. It requires precise alignment when inputting, and the password needs to be manually destroyed after unlocking, which takes time to unlock. Longer, usually more than half a minute, so use less,

Chinese patent "button-type mechanical combination lock cylinder", the patent number is "02115653.0", discloses a kind of button-type combination lock, its structure is as follows figure 1 As shown, but in the process of inputting the password, because the positioning piece 20 and the limit tooth 21 arranged behind the lock cylinder jointly limit the combination key 22 to push the slide plate 23, and the width of the step at the back of the combination key 22 is different, if the combination key is pressed correctly 22. The positioning piece 20 will move on the limit tooth 21. If you press the wrong password key 22 and the step at the rear of the password key 22 cannot be inserted into the hole, the baffle plate will be pushed to make the positioning piece 20 and the limit tooth 21 return, and The sound or feel will be slightly different, and it is easy to crack the code by hand or sound, or to destroy the lock in a violent way.
