A hidden anti-violence lock cylinder

Abstract

The invention relates to a hidden anti-violence lock cylinder; the lock body (1) has a rotary sleeve (3), a rotor (4) and a lock cylinder (5), so that the rotary sleeve (3) and the rotor (4) Both the rotating sleeve (3) and the lock body (1) can perform relative rotational movement; there is a rectangular groove between the lock cylinder (5) and the rotating sleeve (3), and there are elongated side columns (9 ); there are one or more small round through holes at the bottom of the rectangular groove; a third columnar marble (10) is placed in the hole; there is also a second columnar marble (8) on the rotating sleeve (3); in the rotor ( 4) The radial blind holes are filled with compression springs (6) and first columnar marbles (7); the present invention can realize that when the key is not inserted, the rotor can rotate relative to the swivel, and the swivel is locked relative to the lock body; It prevents the use of force-opening tools and rotation to unlock, has good anti-theft performance, and is suitable for different rotation locking drive bolts.

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
