Hidden synchronous spring lock unlocking method, key and lock cylinder

Abstract

The invention discloses a concealed synchronous pin tumbler lock. The pin tumbler lock mainly comprises a key and a lock cylinder. The key mainly comprises a key handle shell, a reset spring, a reset spring strip, a baffle locking piece, a baffle locking gear, a cylindrical shaft, a baffle motion guiding piece, a baffle and a tooth pattern part. The lock cylinder mainly comprises a lock cylinder shell, a compensation block, a spring strip, a shelter, a lock cylinder rotor, a rightward pin tumbler, a leftward pin tumbler, a lock cylinder bottom plate, a clamping spring and a spring. According to the lock cylinder in the pin tumbler lock, when the lock is opened with the key, the interior of the lock cylinder must be totally separated from the outside, and therefore the possibility of technical unlocking does not exist. Because the pin tumblers will not touch the inner wall of the lock cylinder shell, it is impossible that the actual positions of the pin tumblers are sensed by poking the pin tumblers, and therefore technical unlocking cannot be achieved through the attempt to poke the pin tumblers to the unlocking positions. The position, allowing the lock to be opened, of each pin tumbler is unique, and thus pin tumbler skip unlocking can be avoided. The shapes and the arrangement mode of the pin tumblers are changed, and thus the secret key amount of the lock is greatly increased. The technical requirement for manufacturing of the lock is not substantially raised, and thus the production cost will not be increased substantially.

Description

technical field [0001] The present invention relates to a mechanical tumbler lock, in particular to a method for unlocking a hidden synchronous tumbler lock, a key and a lock cylinder, in particular to a method for unlocking a hidden synchronous tumbler lock, a key and a lock cylinder that effectively prevent technical opening. Background technique [0002] At present, there are many shortcomings or deficiencies in the existing mechanical lock cylinders: 1. There is the possibility of technical unlocking, common methods, methods and techniques for technical unlocking: Ⅰ. Using a certain way and method to sense the position of the marbles, and to achieve the purpose of technical unlocking by fiddle with the pins so that the pins are finally in the unlocking position; Ⅱ. Use continuous attempts to fiddle with each marble to achieve the purpose of breaking each; Ⅲ. Under normal circumstances, the two marbles in the same pinhole are close together, so that the lock can only be ...

Problems solved by technology

[0003] Aiming at the existing mechanical lock cylinder, the object of the present invention is to provide a method for unlocking a hidden synchronous pin lock and the key and the lock cylinder, aiming to completely separate the inside of the lock cylinder (the part where the pins are installed) from the outside when the key is used to unlock the lock. So that there is no possibility of technical unlocking
