Description

Prevent twisting safe lock core based on magnetic force

Technical Field

The utility model belongs to the technical field of the tool to lock and specifically relates to a prevent twisting safe lock core based on magnetic force.

Background

The illegal unlocking methods which are popular internationally nowadays are many: the Lock is unlocked by a Bump key (English) and a drill bit, pulled to pull a Lock cylinder, pried to Lock by a Lock tool and the like. And the illegal unlocking prevention technology is also various along with the appearance: the lock core is a pick-proof lock core, a drilling-proof lock core, a pulling-proof lock core, an anti-torsion lock core (anti-snap), an anti-bump key lock core (anti-bump) and the like.

At present, some thieves also start to steal by means of forced unlocking, the thieves use a special sleeve rod to sleeve the head of the lock cylinder at one end outside the door or use locking pliers to clamp the head of the lock cylinder at one end outside the door, then use a force to pull up and down or pull left and right, so that the weaker middle part of the lock cylinder is broken to destroy the structure of the lock cylinder, and the thieves can easily pull out the broken lock cylinder to unlock the lock because parts in the lock cylinder can be separated from each other.

Since 2013, a series of anti-twisting lock cylinders are developed and designed in succession in the next half year, such as patent numbers:

201320826547.8, 201320768059.6, 201320768384.2, 201320662229.2, 201420206310.4, and the like; the main measures of the lock core body are to reinforce the middle part of the lock core body and to arrange an anti-screwing groove to prevent the lock core from being screwed off from the middle part. Subsequently, a series of anti-theft lock cylinders with locking mechanisms are developed and designed, such as patent numbers: 201420559153.5, 201420754186.5, 201420586337.0, etc., the locking mechanism of these lock cylinders has similar working principle, when the lock cylinder is unlocked by violence, the lock cylinder breaks at the anti-twist groove, the inner rotating piece moves forward, the bayonet lock falls into the locking hole under the action of gravity and spring force to play the anti-theft effect; however, in subsequent production and test, we find that sometimes (the occurrence probability is small) the locking fails due to the fact that the falling speed of the bayonet lock is not fast enough, and then the failure causes may be the following points after analysis: the frictional resistance between the bayonet and the hole wall is large (when the component is installed, some grease may remain on the surface); the long-term compression of the spring causes a spring malfunction or the spring seizes. Therefore, further improvement of the anti-theft structure of the lock cylinder is required.
