Abstract

The invention relates to an anti-prizing separating structure used for a lock, which consists of a lock head, a driving gear, a driven gear and a part used for fixing the lock head. An elastic part is arranged between the lock head and the part used for fixing the lock head. When in normal use, a lock body is comparatively fixed in virtue of the elastic part; when a lock cylinder is twisted by an abnormal torque, the lock cylinder drives the lock body to turn and also drives the meshed driving and driven gears to be separated, so as to lead the torque brought to the clock cylinder for separating to fail. The invention has the advantages of simple structure, easy and simple manufacture, low cost. The lock heads installed on various bins, cases and automobiles, etc. objects all can adopt the structure of the invention, so the invention is provided with a wide application scope and a strong practicality.

Description

technical field [0001] The invention relates to the structure of a lock, in particular to an anti-pick lock capable of separating torsional force and idling. technical background [0002] All the separated anti-theft locks currently disclosed have their separated structures arranged in the lock body or in the lock cylinder. Although such designs can achieve the purpose of anti-prying, anti-technical unlocking, and even anti-drilling, these design structures are complicated, resulting in As the difficulty in the manufacturing process increases, the manufacturing cost will also increase accordingly. At present, the vast majority of thieves use the means of prying to unlock the lock, and there are not many means of using technology and electric drills to unlock the lock. Therefore, although the above-mentioned technology can prevent the lock from being opened illegally, due to cost and other reasons, the lock of this structure is not really used. not much. But because a large...
