Abstract
The invention discloses a multifunctional anti-disengaging nut which comprises a base, a nut body, a spring pad, a spring clamping ring, a circular ring groove and a thread. The thread is arranged in a through hole of the nut body. A punching device exerts pressure on the upper portion of the nut body to make the upper portion of the through hole of the nut body change from the round shape into the oval shape. At least two screw threads can be arranged on the portion, changing into the oval shape, of the upper portion of the through hole of the nut body. The circular ring groove is formed in the bottom of the nut body. The spring pad is arranged in the circular ring groove. The base is inserted into the circular ring groove. The spring pad is arranged above the base. The spring clamping ring is arranged in the circular ring groove. The spring clamping ring stops the base from disengaging from the circular ring groove. The base is formed by a circular ring body and a connecting body arranged on the circular ring body. A through hole of the base is communicated with the through hole of the nut body. Compared with the prior art, the nut can prevent the surface of a fixed object from being damaged, labor is saved in the screwing process, the dual anti-engaging effect is achieved, and the anti-disengaging effect of the anti-engaging nut is good.
Description
[technical field]
The present invention relates to the technical field of nut, particularly a kind of technical field of multi-functional Anti-loosing screw cap.
[background technique]
The internal thread that the nut generally used in the market generally comprises nut body, is formed in the cavity in nut body and is formed on the inwall of nut body.In use, only need nut to be tightened in above bolt.But, in some mechanical structures, easily produce vibration due in the process that device uses, thus cause nut to loosen, once unexpected getting loose occurs nut, often cause linkage structure to disintegrate, cause plant normally to run.Though bond in the mode of bolt and the sealed rear utilisation point glue of nut, but still can lose efficacy because of brittle after long-time use, cause bolt and nut still to there is the possibility got loose, make troubles to production.Although Anti-loosing screw cap has also appearred in market, when fastening latter stage, the surface of Anti-loosing screw cap and fixation rubs, and easily causes the surface damage that is fixed, and tightens effort, and anti-loose effect is not fine.
[summary of the invention]
Object of the present invention solves the problems of the prior art exactly, propose a kind of multi-functional Anti-loosing screw cap, can avoid fixation surface damage, tighten laborsaving, and anti-nut gets loose effective.
For achieving the above object, the present invention proposes a kind of multi-functional Anti-loosing screw cap, comprise pedestal, cap body, spring pad, spring collar, ring groove and screw thread, screw thread is provided with in the through hole of described cap body, exerted pressure by punch assembly in the top of described cap body, the through hole top of cap body is become elliptical shape by round-shaped, the part that the through hole top of described cap body becomes elliptical shape at least can set two screw threads, the bottom of described cap body is provided with ring groove, spring pad has been inserted in described ring groove, pedestal is inserted with in described ring groove, described spring pad is located at the top of pedestal, spring collar has been inserted in described ring groove, spring collar stops that pedestal is deviate from ring groove, described pedestal is made up of cirque body and the connecting body be located on cirque body, the through hole of described pedestal communicates with the through hole of cap body.
As preferably, the height dimension of described connecting body adds that the thickness size of spring pad is at least greater than the depth dimensions of ring groove.
As preferably, described connecting body and cap body are rotatably connected, and the top of described connecting body is provided with anticreep step, and described spring collar is located at the below of anticreep step, is provided with the draw-in groove matched with spring collar in described ring groove.
As preferably, described toric outside dimension is at least greater than the orthohexagonal cornerwise length of cap body, and described toric bottom area is greater than the apex area of connecting body.
As preferably, the lower end of described toric top and connecting body is one-body molded fixing.
Beneficial effect of the present invention: the present invention is by exerting pressure the top of cap body by punch assembly, the through hole top of cap body is become elliptical shape by round-shaped, can be closely sealed with screw rod, and the reaction force that the cap body after tightening is obtained by the cooperation of spring pad and pedestal, stop that cap body rotates to loosen, connecting body and cap body are rotatably connected, toric bottom area is greater than the apex area of connecting body, the frictional force of cirque body and fixation is greater than the frictional force of connecting body and cap body, in rundown process, pedestal does not rotate, compared with prior art, fixation surface damage can be avoided, tighten laborsaving, and reach dual anti-loose, anti-nut gets loose effective.
Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.
