Description
Technical field:
The utility model relates to a kind of anti-theft device, is specifically related to the anti-drilling self-locking device of a kind of secret room.
Background technology:
Important property and various valuables often are positioned in the secret room, and the theftproof performance of secret room is for placing the wherein safe decisive role of article, and the burglar often opens or destroy the secret room locking system by boring, the theft property.Therefore, strengthening the difficulty that secret room is opened in boring, is the key point that improves the secret room theftproof performance.
Summary of the invention:
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of simple in structure, latch is automatic, self-locking is reliable, significantly improve the anti-drilling self-locking device of secret room of pirate of the open secret room difficulty.
The technical solution adopted in the utility model is: the lock box body of the anti-drilling self-locking device of this secret room is processed with grease chamber or air chamber, grease chamber or air chamber connect with oil cylinder or cylinder respectively, oil cylinder piston or cylinder piston connect the self-locking of driving removable pin, perhaps oil cylinder piston or cylinder piston connect self-locking in the lock slots that drives removable pin insertion dead bolt, oil cylinder piston, cylinder piston or oil cylinder piston connector, cylinder piston connector connect spring one end, and the spring other end is connected on lock box body or the fixture.
In the technique scheme, removable pin can be dead bolt, also can be the locking piece of door bolt or door bolt, and the locking dead bolt.
The utility model is because the lock box body is processed with grease chamber or air chamber, and in the lock box body, install and fix oil cylinder or cylinder, oil cylinder or cylinder connect with grease chamber or air chamber respectively, oil cylinder or cylinder be supporting slidable piston, piston or piston connector are connected with spring, removable pin also is installed in this device, and this removable pin and piston can be driven by spring.When the robber opens the secret room door by boring, grease chamber or air chamber are leaked, pressure reduces to zero, the compression spring energy discharges, thereby driven plunger drives the removable pin self-locking or drives in the lock slots of removable pin insertion dead bolt, automatically locks latch, can not only be antitheft, and simple in structure, implement easily, be the novel anti-theft device of a kind of family and unit secret room door lock.
