Hidden anti-violence lock core

Abstract

The invention relates to a hidden anti-violence lock core which is characterized in that a lock body (1) of the hidden anti-violence lock core is internally provided with a rotating sleeve (3), a rotor (4) and a lock liner (5); the rotating sleeve (3) and the rotor (4) can make rotating motion relative to each other; the rotating sleeve (3) and the lock body (1) can make rotating motion relative to each other; a rectangular slot is formed between the lock liner (5) and the rotating sleeve (3), and contains a rectangular side column (9); one or more small circular through holes are formed in the bottom of the rectangular slot, and contains or contain a third columnar marble or third columnar marbles (10); a second columnar marble (8) is arranged in the rotating sleeve (3); and a radial blind hole of the rotor (4) is filled with a compression spring (6) and a first columnar marble (7). The hidden anti-violence lock core can realize the effects that when an unlocking key is not inserted, the rotor can rotate relative to a rotating ring, and the rotating ring is locked relative to the lock body; the use of a brute-force unlocking tool is avoided; rotary unlocking is achieved; and the hidden anti-violence lock core has good anti-theft performance and is applicable to different rotary locking driving pins.

Description

technical field [0001] The invention relates to a lockset, that is, a hidden anti-violence lock cylinder. Background technique [0002] At present, the popular side post marble locks on the market, also known as "atomic" locks, use external force to push or rotate the lock cylinder containing the key socket to directly or indirectly unlock the lock. The key socket of this anti-theft lock cylinder There are many shapes such as: "once", "cross", "semi-arc", "plum blossom", "cylindrical" and so on. The whole body of the anti-theft lock is made of steel. On the surface, the anti-theft lock has very good anti-theft performance, and the market is also very popular. However, in real life, practical cases of theft of this lock often occur, and the lock cylinder is destroyed by a lawless person with a force-opening tool or a miniature electric drill, and the lock cylinder can be opened technically in a few seconds. Because this anti-theft lock has a kind of very big technical desig...

Problems solved by technology

But this application relies on the combination of the elongated side convex pin and the long groove on the outer rotating surface of the swivel to realize the unlocking, so it is required that the long groove on the outer rotating surface of the swivel and the rectangular through hole of the lock body cooperate with a very high precision, otherwise a slight misalignment will cause the lock to be unlocked. It will affect the up and down movement of the long side convex pin, resulting in the obstruction of unlocking
