Description

Gate staggered form drives anti-theft cylinder lock and key thereof outward

Technical field

The invention relates to a kind of gate staggered form and drives anti-theft cylinder lock outward, belongs to a kind of of lockset.

Background technology

In existing lockset, be all that key is inserted in lock core, by rotating key, drive the internal construction of lockset, realize the opening and closing of door lock.But its shortcoming is that the pellet in lock core may suffer artificial interference and be unlocked, can not play antitheft effect; If key is firmly excessive in lock core in addition, also can cause the fracture of key and stay in lock core, cause lockset not open, the rotation of simultaneously long-term lock core, also causes the life-span of lock core to decline.

Summary of the invention

The technical problem that the invention will solve is to provide a kind of gate staggered form and drives anti-theft cylinder lock outward; this theftproof lock reaches by outer power the object that lock core rotation is opened door lock; the pellet of its lock core is staggered form gate structure simultaneously; not only antitheft but also protected the structure of lockset, the application life of having improved lockset.

For overcoming the above problems, the concrete technical scheme of the invention is as follows: a kind of gate staggered form drives anti-theft cylinder lock outward, comprise lock tube and lock core, in lock core, be provided with several locked positions, the through hole of locked position is straight line under nature, at the two ends up and down of locked position, be respectively equipped with the gate pellet of varying length, on lock tube, be provided with quantity and the position radial direction through hole corresponding with gate pellet, one end of through hole is by rivet shutoff, pellet under connecting by slinky spring above rivet, lower pellet contacts with gate pellet below, gate pellet upper surface is provided with pellet, upper pellet is by hard spring connection expansion link, excircle at lock tube is provided with cam set, the cam of cam set contacts with corresponding expansion link, the original position of cam set is the original position of expansion link, and the final position of cam set is for compression expansion link late gate pellet is compressed by spring force or the position of the rear retraction lock core of release inside, on lock core, be provided with pushing hands, outside at lock tube is provided with handle, and handle is flexibly connected with cam set by transmission mechanism.

Described transmission mechanism is that cam set is hollow-core construction, and the inner end of handle is provided with square shaft, square shaft and cam set coaxial cooperation; Side in cam set is provided with balance staff, and the outer end of balance staff is provided with nut; In balance staff, be provided with limited block, between limited block and nut, by overload spring, be connected; Wherein the excircle of lock core is provided with lock core control lever, and lock core control lever is corresponding with the position of nut.

Described lock core and lock tube are provided with cross spacing hole corresponding to position diametrically, in cross spacing hole on lock tube, be provided with outer pellet, outer pellet is divided into respectively two sections and connect by hard spring, pellet in end in contact in outer pellet, interior pellet is connected with the cross spacing hole in lock core by back-moving spring; Lock tube is stretched out in the outer end of pellet outside, and contacts with the end of fork, and fork can swing by central axis, and the upper end of fork contacts with cam set.

The matching used key of a kind of and above-mentioned theftproof lock, the side up and down of key body is respectively equipped with gate holding tank alternately, its position is corresponding with the position of locked position, and when the top of locked position or bottom enter into respectively in corresponding gate holding tank, upper and lower pellet is retracted in lock core simultaneously; Wherein the bottom surface of gate holding tank is deeper than the axis of key body; On key body, be provided with lockhole, the position of lockhole is corresponding with the position of interior pellet.

This gate staggered form drives anti-theft cylinder lock to adopt the bar gate type pellet of upper and lower alternating expression outward, can prevent that soft or hard material from entering lock core, realizes the object of unblanking; The control to cam set by handle simultaneously, realizes the folding of cam set regulating gate pellet, realizes simultaneously and opens and closes lockset.

Transmission mechanism has adopted balance staff and overload spring, has avoided balance staff to be subject to overload power and the phenomenon damaged occurs, and has improved the application life of lockset.
