Abstract

The invention discloses an anti-theft lock. The anti-theft lock comprises a lock shell and a lock liner; a lock liner hole for the lock liner to be clamped in is formed in the lock shell; a security rod lifting groove is formed in one side of a key hole of the lock liner and is internally provided with a security rod; a security rod clamping position is arranged in the lock liner hole; the lock liner is further provided with a blade hole in which a plurality of blades are arranged; each blade is provided with a blade inner hole in which a blade inner clamping block is arranged; each blade is provided with a blade upper clamping groove; a locking blade is further arranged in the blade hole, is provided with the blade inner holes and the blade upper clamping grooves, and is further provided with a clamping block and a blade locking groove; and the security rod is provided with an avoiding part and a stop block. The anti-theft lock is simple in structure and convenient to assembly, can effectively prevent the technological opening, and is high in anti-theft performance, ingenious in design, reliable, stable in performance, convenient to machine and wide in application range.

Description

[0001] 【Technical field】 [0002] The invention relates to an anti-theft lock. [0003] 【Background technique】 [0004] The so-called technical opening is to implement non-key opening without destroying the lock. In the lock industry in the world, there are usually two methods and means to prevent technical opening: one is to increase the number combination by increasing the number of keys to delay the technical opening time; the other is to increase the difficulty of technical opening by improving the processing accuracy. But this does not fundamentally solve the problem of anti-technology opening. Because the mechanical lock is limited by its structure, the hidden danger of technical opening cannot be completely eliminated. The method for general technical opening of the blade lock is to adopt the stirring blade, so that when the blade can be inserted into the blade hole on the blade as a key, the bumper falls into the draw-in groove on the blade so that the lock cylinder c...
