Abstract

A lock bulb with a spiral keyhole comprises a lock body, a lock cylinder, spring mechanisms and an anti-drilling cover, wherein the lock cylinder is movably fit in the lock body, is provided with the spiral keyhole and is composed of a lock cylinder body and a spiral tube; the spiral tube is provided with the spiral keyhole; and the lock body, the lock cylinder body and the spiral tube are provided with the spring mechanisms. When in use, the lock bulb is fixed in the lockset, the spiral key is screwed into the spiral keyhole of the lock bulb to ensure the outer spring to leave the position which locks the lock cylinder to turn, the spiral key is turned and the lock cylinder can turn along with the spiral key to open the anti-theft lock. As the keyhole is screwed in a spiral way, the lock is hard to open by the thieves with master keys. The spring mechanisms can be arranged along the spiral keyhole, thus increasing the spring setting passwords and improving the anti-theft performance of the anti-theft locks.

Description

Lock bulb with spiral keyhole

Affiliated technical field

The present invention relates to a kind of lock gall, particularly a kind of lock bulb with spiral keyhole.

Background technology

The keyhole of existing lock gall all is straight, and the robber is easier to open with master key, and a kind of master key is difficult to insert the lock bulb with spiral keyhole of keyhole, has become the needs that people improve the theftproof lock theftproof performance.

Summary of the invention

The present invention seeks to overcome the deficiencies in the prior art, a kind of lock bulb with spiral keyhole is provided, be used to improve the theftproof performance of theftproof lock.

The technical solution used in the present invention is: include lock body, lock core, billiard mechanism and anti-drilling lid, lock core is actively tied in the lock body, and lock core is provided with the spiral key hole, and lock core is made of lock core body and helix tube, helix tube is provided with the spiral key hole, and lock body, lock core body and helix tube are provided with billiard mechanism.

The supporting spiral key that is provided with of lock bulb with spiral keyhole, the helical angle of spiral key is identical with the helical angle in spiral key hole, the pitch of spiral key is identical with the pitch in spiral key hole, the external diameter in the helix cross section of spiral key is littler than the hole internal diameter in spiral key hole, to guarantee that spiral key can screw in the spiral key hole.During use, spiral key is screwed in the spiral key hole, after spiral key screws in the spiral key hole, moved the position of outer pellet shot from a slingshot in the billiard mechanism and interior pellet shot from a slingshot, make the interface of outer pellet shot from a slingshot and interior pellet shot from a slingshot just in time be positioned at the contact position of lock body and lock core, outer pellet shot from a slingshot left and blocked the position that lock core rotates this moment, the rotation spiral key, lock core just can be opened theftproof lock along with spiral key rotates.

The invention has the beneficial effects as follows: screw in because the keyhole of lock bulb with spiral keyhole is a mode with spiral, the robber is difficult to master key lock be opened; Because billiard mechanism is provided with along the spiral key hole, the number of positions that the spiral key hole is provided with billiard mechanism increases, and has improved the theftproof performance of theftproof lock.
