Abstract

The invention discloses an anti-theft lock with a bending round keyhole. The anti-theft lock comprises a lock tank and a key, wherein the lock tank comprises an outer lock tank, an intermediate lock tank and an inner lock tank; the outer lock tank consists of an outer lock body and an outer lock cylinder; the intermediate lock tank consists of an intermediate lock body and an intermediate lock cylinder; the inner lock tank consists of an inner lock body and an inner lock cylinder; the outer lock cylinder is provided with a first keyhole; the intermediate lock cylinder is provided with a second keyhole; the inner lock tank is provided with a third keyhole; a keyhole formed by the first keyhole, the second keyhole and the third keyhole is a bending keyhole; the outer lock body is connected with the intermediate lock body fixedly; the intermediate lock body is connected with the inner lock body fixedly; the outer lock cylinder is connected with the intermediate lock cylinder fixedly; the intermediate lock cylinder is connected with the inner lock cylinder fixedly; and the key is a bendable round key. Because the keyhole of the anti-theft lock with the bending round keyhole is bending, the difficulty in unlocking with a master key by a theft is increased, and the anti-theft performance of the anti-theft lock is improved.

Description

Crooked circle keyhole theftproof lock

Affiliated technical field

The present invention relates to a kind of theftproof lock, particularly a kind of crooked circle keyhole theftproof lock.

Background technology

At present, the keyhole of theftproof lock all is straight on the market, and the robber is easier to open with master key, and a kind of crooked circle keyhole theftproof lock has become the needs that people improve the theftproof lock performance.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, a kind of crooked circle keyhole theftproof lock is provided, improve the theftproof performance performance of theftproof lock.

The technical scheme of taking of the present invention is: crooked circle keyhole theftproof lock, include lock gall and key, and lock gall is made up of outer lock gall, middle lock gall and interior lock gall; Outer lock gall is made up of outer lock body and outer lock core, and outer lock body and outer lock core are provided with first billiard mechanism; Middle lock gall is made up of middle lock body and middle lock core, and middle lock body and middle lock core are provided with second billiard mechanism; Interior lock gall is made up of interior lock body and internal cylinder, and interior lock body and internal cylinder are provided with the 3rd billiard mechanism; Outer lock core is provided with first keyhole, and middle lock core is provided with second keyhole, and internal cylinder is provided with three-keyhole; The keyhole that is made up of first keyhole, second keyhole and three-keyhole is crooked keyhole; Outer lock body is fixedly connected with middle lock body, and middle lock body is fixedly connected with interior lock body; Outer lock core is fixedly connected with middle lock core, and middle lock core is fixedly connected with internal cylinder; Key is flexible round key.

During use; Flexible key is inserted first keyhole of outer lock core; Second keyhole of lock core during key gets into through the back of turning round; Get into the three-keyhole of internal cylinder then by turning round again; Under the effect of first billiard mechanism, second billiard mechanism and the 3rd billiard mechanism spring; The outer pellet shot from a slingshot of outer lock core and outer lock body first billiard mechanism and the contact position of interior pellet shot from a slingshot just in time are positioned at the position of the contact surface of outer lock body endoporus and outer lock core cylindrical, and the outer pellet shot from a slingshot of middle lock core and middle lock body second billiard mechanism and the contact position of interior pellet shot from a slingshot just in time are arranged in the position of the contact surface of lock body endoporus and lock core cylindrical, and the outer pellet shot from a slingshot of internal cylinder and interior lock body the 3rd billiard mechanism and the contact position of interior pellet shot from a slingshot just in time are positioned at the position of the contact surface of lock body endoporus and internal cylinder cylindrical; Key makes outer lock core, middle lock core and outer lock core simultaneously with key turns, and the part of unblanking of internal cylinder drives the unlocking mechanism rotation can open theftproof lock.

The invention has the beneficial effects as follows: because the keyhole of crooked circle keyhole theftproof lock is crooked, increased the difficulty that the robber uses master key to open, improved the theftproof performance of theftproof lock.
