Embodiment Construction

[0014] Concrete structure of the present invention can refer to figure 1 , figure 1 Reflected in is a structural diagram of an embodiment of a lock cylinder. The lock core housing 8 is axially provided with a mounting hole for inserting the rotating lock core, and the rotating lock core is movably inserted therein. The main rotating lock cylinder 6 is connected with the unlocked twist piece 5, the rear end of the auxiliary rotating lock cylinder 7 is adjacent to the front end of the main rotating lock cylinder 6, the front end of the auxiliary rotating lock cylinder 7 is in contact with the front end cover 1, and the key of the front end cover 1 Hole 9 is corresponding, and the effect of overcoat 3 is the torsion plate 5 of positioning rotating lock core 6,7 and unblanking. The pins 4 (two sections) are radially symmetrically arranged in four groups in the corresponding holes of the lock core housing 8 and the rotating lock core 6, 7, so as to adapt to the needs of the cross...

Abstract

The invention relates to lock using theft protection lock core device that includes lock core case, rotating lock core, and lock core front cover. It adds one or more grade safety shields to the traditional lock. The invention could effectively enhance the prizing-proof ability. It sharply increases the safety and reliability of the mechanical lock.

Description

technical field [0001] The invention relates to a universal lock core of a mechanical lock. Background technique [0002] Existing mechanical locks include a lock case, a lock cylinder and a lock tongue, among which the lock cylinder is the most critical part of the lock body, and the lock tongue is connected to the end of the lock cylinder. It is required to be designed in a form that meets the requirements of use. The traditional mechanical lock has a wide range of applications. According to its structural characteristics, it is easy to open the lock under the operation of a person with lock-picking skills by using a special and self-made unlocking tool. Analyzing the above-mentioned special unlocking methods, it can be found that no matter using special tools or other methods, the pins in the lock cylinder will be aligned one by one, and finally the lock will be opened. Some illegal lock pickers use a screwdriver to forcibly twist the lock cylinder to open the lock. Du...
