Problems solved by technology
The problem with this kind of lock is that it is easy to open it with non-matching key unlocking tools, such as master keys, unlocking guns, etc., because these unlocking tools can make the two marbles of each marble group contact the lock cylinder and the lock body one by one. Misalignment of the surfaces until their contact surfaces all coincide with the contact surfaces of the lock cylinder and the lock body
Because there are above-mentioned deficiencies, the safety performance and anti-theft performance of this pin lock are all bad.

Disclosed is an anti-theft lock core, comprising a hollow casing (500), wherein a drive barrel (400) is rotatably provided in the casing (500), a lock cylinder (100) is rotatably provided in the drive barrel (400), one side of the lock cylinder (100) is axially provided with a strip-shaped groove (101), multiple notches (102) penetrating the strip-shaped grooves (101) are radially provided at intervals on the lock cylinder (100), a scissor-shaped snap-fastener (200) is provided in each notch (102), the scissor-shaped snap-fasteners (200) are composed of two flush snap-brackets (201), the two snap-brackets (201) are respectively provided with snap-legs (204) extending into two sides of a lock hole, and a spring or elastic piece (203) is provided between the two snap-brackets (201). When a key is inserted, key teeth make the two snap-legs (204) of the corresponding scissor-shaped snap-fastener (200) open or close, thereby making the spring or elastic piece (203) change shape and make an upper end opening of the two snap-brackets (201) engage with the strip-shaped grooves (101), the drive barrel (400) is provided with strip-shaped holes (401) fitting with the strip-shaped grooves (101), the casing (500) is provided with accommodating grooves (502) fitting with the strip-shaped holes (401), and one drive strip (300) is elastically provided in an accommodating groove (501) and a strip-shaped hole (401).The lock core has the advantages of being capable of preventing forced unlocking and damaging unlocking.
Description
technical field [0001] The invention relates to an anti-theft lock, in particular to an anti-theft lock cylinder capable of preventing strong unlocking and destructive unlocking. Background technique [0002] The problem of property and information security has always been a problem that all walks of life attach great importance to, so the application of locks is ubiquitous, and the pin lock has always been the most widely used product. The usual pin lock head is locked by the pin to lock the cylinder to rotate. Each pin group in the lock is composed of two pins. When the lock is unlocked, the contact surface of the two pins coincides with the contact surface of the lock cylinder and the lock body. The lock core can rotate relative to the lock body. When locking, the contact surface of the two pins The contact surface between the lock cylinder and the lock body does not coincide, and the lock cylinder cannot rotate due to the blocking effect of the marble. The problem with ...
