Anti-drilling structure of lock cylinder and lock liner
The anti-drilling structure comprises a lock shell, the lock shell is provided with a first containing cavity, the lock container is arranged in the first containing cavity, the lock container is provided with a lock hole for a key to be inserted in, pin holes are symmetrically formed in the two sides in the lock hole in an inwards-concave mode, and first anti-drilling pins are arranged in the pin holes. One side of the first anti-drilling pin protrudes outwards to form a platform protruding part used for abutting against threads of a self-tapping screw located in the lock hole. The platform convex parts are additionally arranged on the anti-drilling pins I on the two sides of the lock hole, so that the daily anti-drilling requirement is met, and meanwhile, when a high-hardness self-tapping screw is used for a tensile test, the platform convex parts abut against threads of the self-tapping screw to damage the threads of the self-tapping screw, so that the threads of the self-tapping screw cannot be engaged with the threads of the anti-drilling pins I, and the service life of the anti-drilling pin I is prolonged. Therefore, when the self-tapping screw receives pulling force, the self-tapping screw is not meshed with the first anti-drilling pin, so that only the self-tapping screw is pulled out of the lock hole, but the lock cylinder cannot be driven to be pulled out, and the pulling resistance test of the lock cylinder can be effectively passed.
本发明公开一种锁芯锁胆的防钻结构，包括锁壳，所述锁壳上具有收容腔一，所述收容腔一内设置有锁胆，所述锁胆上设置有供钥匙插入的锁孔，所述锁孔内两侧对称内凹有销孔，所述销孔内设置有防钻销一，所述防钻销一一侧外凸有供抵接位于锁孔内自攻螺丝螺牙的平台凸部。通过在锁孔两侧的防钻销一上增设平台凸部，进而满足日常防钻要求的同时，当进行耐拉测试使用高硬度自攻螺丝时，通过平台凸部与自攻螺丝的螺牙抵接，进而破坏自攻螺丝的螺牙，使自攻螺丝的螺牙无法与防钻销一螺纹咬合，从而当自攻螺丝接收拉力时，因自攻螺丝与防钻销一无咬合关系，从而只会将自攻螺丝从锁孔拉出但无法带动锁胆拉出，进而有效通过锁胆的耐拉测试。
