Abstract
The utility model relates to an anti-drilling mechanism of a door lock, comprising a lock body and a lock core shaft, wherein the lock core shaft is arranged in the lock body, an anti-drilling piece is arranged in the lock core shaft, a tooth profile which is matched with a key jack of the lock core shaft is arranged in the anti-drilling piece, and the anti-drilling piece is inserted into a predetermined slot from the side of the lock core shaft. The anti-drilling mechanism of the door lock overcomes the defect of poorer anti-drilling performance of the lock core shaft in the common door lock. According to the design, an anti-drilling piece can effectively prevent the lock core shaft from being destroyed by tools, such as a drill bit, and the like. The anti-drilling mechanism of the door lock has simple and compact structure, high reliability and strong theftproof performance.
Description
Technical field
The utility model relates to the anti-drilling mechanism of a kind of door lock.
Background technology
Common door lock pin axle is generally copper, its anti-drilling poor-performing, and the burglar can destroy by the instrument of drill bit and so on and open, so its theftproof performance also is difficult to satisfy instructions for use.
Summary of the invention
In order to overcome the problem of the anti-drilling poor-performing of common door lock pin axle in the prior art, the utility model provides a kind of door lock anti-drilling mechanism, and the structure design of this anti-drilling mechanism of door lock is simply compact, reliability is high, theftproof performance is strong.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the lock core shaft in lock body and the lock body, be provided with anti-drilling sheet in lock core shaft.
Be provided with the profile of tooth that the key hole with lock core shaft is complementary in the anti-drilling sheet.
Anti-drilling sheet is in the default slot of the sidepiece insertion lock core shaft of lock core shaft.
The utility model is by above-mentioned specific design, and anti-drilling sheet can effectively prevent the destruction of the instrument of drill bit and so on to lock core shaft, has advantage simple and compact for structure, that reliability is high, theftproof performance is strong.
