Description

Make up oblique lock core liner

Affiliated technical field

The present invention relates to a kind of anti-theft lock bladder, particularly the oblique lock core liner of a kind of combination.

Background technology

At present, the keyhole of theftproof lock lock gall all is straight on the market, and the robber is easier to open with master key, a kind ofly makes up oblique lock core liner and has become the needs that people improve the theftproof lock performance.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of combination oblique lock core liner, improve the theftproof lock performance.

The technical scheme of taking of the present invention is: include lock body and lock core, lock core is made of outer lock core, middle lock core and internal cylinder; Outer lock core is fixedly connected with middle lock core, and middle lock core is fixedly connected with internal cylinder; Outer lock core, middle lock core and internal cylinder are actively tied in the cylindrical hole of lock body; Outer lock core is provided with the first keyhole, middle lock core is provided with the second keyhole, and internal cylinder is provided with three-keyhole, and the first keyhole is communicated with the second keyhole, the second keyhole is communicated with three-keyhole, and the first keyhole, the second keyhole and three-keyhole consist of crooked keyhole; Lock body and outer lock core are provided with the first billiard mechanism, and lock body and middle lock core are provided with the second billiard mechanism, and lock body 1 is provided with the 3rd billiard mechanism with internal cylinder.

During use, flexible key is inserted the first keyhole of outer lock core, key is through entering the second keyhole of middle lock core after turning round, then enter the three-keyhole of lock core by turning round again, at the first billiard mechanism, under the effect of the second billiard mechanism and the 3rd billiard mechanism spring, the outer pellet of outer lock core and outer lock body the first billiard mechanism and the contact position of interior pellet just in time are positioned at the position of the contact surface of outer lock body endoporus and outer lock core cylindrical, the outer pellet of middle lock core and middle lock body the second billiard mechanism and the contact position of interior pellet just in time are arranged in the position of the contact surface of lock body endoporus and lock core cylindrical, the outer pellet of internal cylinder and interior lock body the 3rd billiard mechanism and the contact position of interior pellet just in time are positioned at the position of the contact surface of lock body endoporus and internal cylinder cylindrical, rotate key and make outer lock core, middle lock core and outer lock core are 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 the oblique lock core liner of combination is crooked, increased the difficulty that the robber uses master key to open, improved the theftproof performance of theftproof lock.
