Aforementioned patents disclose the structure of existing door lock core, in this lock core structure, its all parts is all directly be enclosed within rotating shaft, finally by locked clip device; This mode causes necessary hand assembled, and efficiency of assembling is low, and labour cost is high.And only adopt its structure of mode of locked clip device firm not, easily loosen.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of energy Automated assembly, high, the well-set screw thread door lock of efficiency of assembling.

For achieving the above object, the utility model provides following technical scheme: a kind of screw thread door lock, comprise panel, spring, rotating shaft, commutation mat, stiffening piece, add solid gear, limited block, described limited block is arranged on the panel, described commutation mat there are two spacing lugs, described limited block matches with described spacing lug, there is a square bar hole described rotating shaft inside, described panel, commutation pad, stiffening piece all has a shape with adding in solid gear, measure-alike through hole, described rotating shaft is successively through described panel, commutation pad, stiffening piece and the through hole added on solid gear, wherein: described rotating shaft both sides respectively has one towards the groove in square bar hole, respectively there is a retention tab through hole both sides in described commutation mat, described groove matches with retention tab clamping, there is external screw thread on the surface of described rotating shaft, described in add solid gear inner side be provided with the internal thread matched with rotating shaft, one end of described spring coordinates clamping with limited block, the other end and groove fit clamping.

Further, described limited block is set to rectangle, and described spacing lug is provided with resistance surface, and described spacing lug is contacted with the side forming surface of limited block by described resistance surface.

Further, there is a projection at the edge of described stiffening piece, the width of described projection and the described fit depressions adding solid gear.

Further, described projection and stiffening piece are integral type sheet metal structural.

By adopting technique scheme, adopting helicitic texture to make panel, commutation pad, stiffening piece and add solid gear to fix in rotating shaft, lock core structure being stablized, not easily loosens; Width and the fit depressions adding solid gear of the projection on stiffening piece, projection can opposed annular structure bend, the groove that protruding clamping enters to add solid gear further fixedly can add solid gear, adds the fixing of solid gear and above-mentioned parts can be made again more stable, result in formation of the structure interfixed; Limited block is set to rectangular structure and replaces traditional cylinder, make limited block and commutation mat between contact from point to face, add lifting surface area peventing member impaired.

Compared with prior art, lock core structure in the utility model, have employed engagement thread and all parts compact siro spinning technology, by automatically assemble namely can directly each component be tightened on turn on, the mode manually originally that instead of is assembled, and produces efficiency of assembling and significantly improves.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.

A kind of screw thread door lock, comprise panel 1, spring 9, rotating shaft 2, commutation mat 3, stiffening piece 4, adds solid gear 5, limited block 6, described limited block 6 is arranged on described panel 1, described commutation mat 3 has two spacing lugs, described limited block 6 matches with described spacing lug, and there is a square bar hole 7 described rotating shaft 2 inside.

Described panel 1, commutation mat 3, stiffening piece 4 all has a shape with adding in solid gear 5, measure-alike through hole, described rotating shaft 2 is successively through described panel 1, commutation mat 3, stiffening piece 4 and the through hole added on solid gear 5, wherein: there is external screw thread on the surface of described rotating shaft 2, the described inner side adding solid gear 5 is provided with the internal thread matched with rotating shaft 2, by spring 9, commutation mat 3, stiffening piece 4 is successively through rotating shaft 2, finally will add solid gear 5 to be threaded connection and to be fixedly connected with rotating shaft 2, such structure can make to add solid gear 5 helicitic texture and fix, by spring 9, commutation mat 3, stiffening piece 4 extrudes fixing, increase frictional force, such structure can not need the jump ring in conventional lock cylinders, not only simplify technique, and make lock core more firm.

Described rotating shaft 2 both sides respectively has one towards the groove 10 in square bar hole 7, respectively there is a retention tab 11 through hole both sides in described commutation mat 3, described groove 10 matches with retention tab 11 clamping, during installing commutation mat 3, retention tab 11 in commutation mat 3 to be aimed at the groove 10 of both sides, square bar hole 7, make it mutual clamping, such structure can make commutation mat 3 fix further in rotating shaft 2, prevents its phase countershaft 2 relative motion.

One end of described spring 9 coordinates clamping with limited block 6, the other end coordinates clamping with groove 10, home position can be sprung back under the effect of spring 9, namely when the mat 3 that commutates is rotated with rotating shaft 2, limited block 6, between two spacing lugs, defines the angle that commutation mat 3 is rotated, ensure that rotating shaft 2 can only rotate fixed angle towards fixed-direction, after have rotated certain angle, spring 9 can recover deformation and get back to original position.

Described limited block 6 is set to rectangle, and described spacing lug is provided with resistance surface, and described spacing lug is contacted with the side forming surface of limited block 6 by described resistance surface.Described limited block 6 replaces cylindrical limited block 6 in conventional lock cylinders, make limited block 6 and commutation mat 3 between contact from point to face, add lifting surface area peventing member impaired.

There is a projection 12 at the edge of described stiffening piece 4, described protruding 12 and stiffening piece 4 be integral type sheet metal structural, the described width of protruding 12 matches with the described groove 10 adding solid gear 5, described protruding 12 can the bending of opposed annular structure, after bending described protruding 12 just in time can be connected to described in add groove 10 place of solid gear 5, the groove 10 that protruding 12 clampings enter to add solid gear 5 further can fixedly add solid gear 5, adding the fixing of solid gear 5 can make again above-mentioned parts more stable, result in formation of the structure interfixed.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
