Technical field

The utility model relates to mechanical lock, relates in particular to a kind of idle rotation lock master structure.

Background technology

Present existing idle rotation lock master structure is made Isolating Switch to establish two block length type side columns in the inside and outside lock core usually, and it is poor in use to have rotary state sometimes, some adopts the vanes block number few, it is not parallel to have clutch block in the use, causes rotary state poor, so the reliability of influence lock.

Summary of the invention

At the shortcoming of prior art, the purpose of this utility model provides a kind of idle rotation lock master structure stable, that theftproof is good of opening.

To achieve these goals, the technical solution of the utility model is: a kind of idle rotation lock master structure, comprise be located in the lock body before, rear lock core, swivel becket and vane group, wherein, be provided with through hole and clutch pellet shot from a slingshot in the nested position of the rear end of preceding lock core column type boss with lock body vertical line direction with rear lock core, spring, be with swivel becket and at boss at the nose circle column type boss of preceding lock core, swivel becket, lock body vertical line direction is provided with through hole and clutch pellet shot from a slingshot, spring, side column two of lock core before two clutch pellets shot from a slingshot all are pressed in and are located at, side column one side is provided with the V-type tongue and is provided with V-type recess face with vane group one side and engages, one side of vane group or center are provided with can be with on the key with the protuberance of tartar, and lock core communicates with the axis key along the vane group groove on the axis before being located at.

Further, also be included in key and vane group and side column when matching two clutch pellets shot from a slingshot just can make to start the rotatable lamella of post lock core.

Preferably, described vane group by two kinds of blades before folded mutually being located at more than 3 and 3 lock core along constituting one in the blade groove on the axis, be provided with V-type recess face in a side of every small pieces and become dislocation with the V-type tongue of side column one side, be provided with at a side of every small pieces and center can with on the key with the protuberance of tartar.Two kinds of blades in the vane group, to folded, opening direction is opposite each other by two front and back for wherein a kind of blade, two shared back-moving springs, every sheet center is provided with can be with on the key with the protuberance of tartar, and a side is provided with the V-type recess; Another side is provided with the V-type recess, and a side is provided with can be with on the key with the protuberance of tartar, and does the dislocation effect with tartar groove on the key, without back-moving spring.

Compared with prior art, the utility model unlatching is stable, theftproof is good.
