Multi-level linkage trigger type high-level anti-theft lock cylinder

Abstract

The invention provides a multistage linkage trigger type high-grade anti-theft lock cylinder. The multistage linkage trigger type high-grade anti-theft lock cylinder comprises an encapsulating shell.A locking device capable of being switched between a closed locking state and an opening unlocking state of a door body and a door frame is arranged in the encapsulating shell. The locking device comprises a lock case detachably and fixedly arranged in the door body, a cylindrical lock cylinder coaxially and rotatably arranged in the lock case in the thickness direction of the door body and a locking execution mechanism, wherein the locking execution mechanism is arranged between the lock case and the cylindrical lock cylinder, can receive driving of the cylindrical lock cylinder and is used for conducting switching between the closed locking state and the opening unlocking state of the door body and the door frame. The locking device of the multistage linkage trigger type high-grade anti-theft lock cylinder further comprises a multi-trigger linkage anti-theft mechanism used for theft prevention, and the multi-trigger linkage anti-theft mechanism is arranged between the cylindrical lock cylinder and the lock case. The multi-trigger linkage anti-theft mechanism is additionally arranged on a traditional pin tumbler lock, the unlocking difficulty of the lock is greatly improved, and the antitheft performance of the lock is improved.

Description

technical field [0001] The invention relates to a lock, in particular to a tumbler lock. Background technique [0002] In daily life, in order to protect the safety of property, various locks are often used, and the tumbler lock is widely used as the most common lock due to its ease of use. As an important daily necessities, people have put forward higher and higher requirements for the safety and anti-theft performance of the pin lock. The common pin lock provided by the prior art generally consists of the following structure, including a lock cylinder, a lock cylinder shell, a vertical Pins and locking actuators, the lock cylinder is rotatably set inside the lock cylinder shell, taking the most common anti-theft lock with cylindrical pins as an example, after inserting the correct key, the pins of each row are in the correct position, that is, the lower pins are exactly in the The lock cylinder and the upper pin are just in the lock shell, so that the lock core can be rot...

Problems solved by technology

As an important daily necessities, people have put forward higher and higher requirements for the safety and anti-theft performance of the pin lock. The common pin lock provided by the prior art generally consists of the following structure, including a lock cylinder, a lock cylinder shell, a vertical Pins and locking actuators, the lock cylinder is rotatably set inside the lock cylinder shell, taking the most common anti-theft lock with cylindrical pins as an example, after inserting the correct key, the pins of each row are in the correct position, that is, the lower pins are exactly in the The lock cylinder and the upper pin are just in the lock shell, so that the lock core can be rotated relative to the lock shell to unlock the lock; if the key is pulled out or the wrong key is inserted, the pin will be between the lock shell and the lock core so that the lock core cannot be rotated. It is possible to use tools to apply torque to the lock cylinder so that the pins can withstand appropriate transverse shear force, and use the force-sensitive dial to separate the upper and lower pins into the holes of the lock case and lock cylinder one by one, so as to realize the technical opening
