Description

Lock core anti-drilling structure capable of preventing damage from exposure of lock core Technical Field The utility model relates to the technical field of lock cylinders, in particular to a lock cylinder anti-drilling structure capable of preventing damage from being exposed out of a lock cylinder. Background Along with the development of society and the improvement of people's safety consciousness, the lockset is widely applied in daily life, and the safety is of great concern. The lock core is used as a core component of the lockset and bears a key anti-theft function. However, many lock cylinders currently on the market have obvious loopholes in design, and the exposed parts of the lock cylinders lack effective protective measures. In an actual use scenario, this defect brings about a number of potential safety hazards. Lawless persons often use the exposed weakness of the lock cylinder and damage the lock cylinder by means of drilling and the like. Once the lock core is drilled, the internal structure of the lock core is damaged, and the anti-theft performance of the lock is greatly reduced, so that lawbreakers can easily unlock the lock, and the property safety of users is seriously threatened. The safety problem caused by the exposed lock core not only brings economic loss to individuals, but also affects the public security and stability to a certain extent. Accordingly, a lock cylinder anti-drilling structure that can prevent damage from the exposure of the lock cylinder has been proposed. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, the present utility model provides a lock cylinder anti-drilling structure capable of preventing damage from the exposure of the lock cylinder, so as to solve the above-mentioned problems in the prior art.
