Abstract
The utility model discloses one and prevent the nut that gets loose, comprise cap body, elastomeric pad, ring groove, internal thread and supporter, the inwall of described cap body is provided with internal thread, the bottom of described cap body is provided with ring groove, elastomeric pad is provided with in described ring groove, described supporter inserts in ring groove, described elastomeric pad is located at the top of supporter, described supporter is made up of hollow cylinder and the round platform be located on cylindrical bottom, described round platform is conical by its shape, compared with prior art, can prevent nut from getting loose, avoid making troubles to production.
Description
[technical field]
The utility model relates to the technical field of nut, particularly a kind of technical field of the nut that prevents from getting loose.
[background technology]
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 frame for movements, easily produce vibration due in the process that device uses, thus cause nut to loosen, once unexpected getting loose occurs nut, often cause syndeton 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.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes one and prevents the nut that gets loose, can prevent nut from getting loose, avoid making troubles to production.
For achieving the above object, the utility model proposes one and prevent the nut that gets loose, comprise cap body, elastomeric pad, ring groove, internal thread and supporter, the inwall of described cap body is provided with internal thread, the bottom of described cap body is provided with ring groove, elastomeric pad is provided with in described ring groove, described supporter inserts in ring groove, described elastomeric pad is located at the top of supporter, described supporter is made up of hollow cylinder and the round platform be located on cylindrical bottom, and described round platform is conical by its shape.
As preferably, described cylindrical height dimension adds that the gauge of elastomeric pad is at least greater than the depth dimensions of ring groove.
As preferably, the great circle mesa diameter size of described round platform is at least greater than the orthohexagonal cornerwise length of cap body.
As preferably, the inwall of described ring groove is provided with step, and described cylinder is provided with the chute matched with step.
The beneficial effects of the utility model: the utility model is by turning cap body, supporter is to elastomeric pad active force, until elastomeric pad is driven plain, the reaction force that cap body after tightening is obtained by the cooperation of elastomeric pad and supporter, stop that cap body rotates to loosen, compared with prior art, can prevent nut from getting loose, avoid making troubles to production.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of nut that prevents from getting loose of the utility model.
In figure: 1-cap body, 2-elastomeric pad, 3-ring groove, 4-internal thread, 5-supporter, 31-step, 51-cylinder, 52-round platform, 53-chute.
[detailed description of the invention]
Consult Fig. 1, the utility model one prevents the nut that gets loose, comprise cap body 1, elastomeric pad 2, ring groove 3, internal thread 4 and supporter 5, the inwall of described cap body 1 is provided with internal thread 4, the bottom of described cap body 1 is provided with ring groove 3, elastomeric pad 2 is provided with in described ring groove 3, described supporter 5 inserts in ring groove 3, described elastomeric pad 2 is located at the top of supporter 5, described supporter 5 is made up of hollow cylinder 51 and the round platform 52 be located on the bottom of cylinder 51, described round platform 52 is conical by its shape, the height dimension of described cylinder 51 adds that the gauge of elastomeric pad 2 is at least greater than the depth dimensions of ring groove 3, the great circle mesa diameter size of described round platform 52 is at least greater than the orthohexagonal cornerwise length of cap body 1, the inwall of described ring groove 3 is provided with step 31, described cylinder 51 is provided with the chute 53 matched with step 31.
Utility model works process:
The utility model one prevents from getting loose nut in the course of the work, turn cap body 1, supporter 5 pairs of elastomeric pad 2 active forces, until elastomeric pad 2 is driven plain, the reaction force that cap body 1 after tightening is obtained by the cooperation of elastomeric pad 2 and supporter 5, stops that cap body 1 rotates and loosens, compared with prior art, can prevent nut from getting loose, avoid making troubles to production.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
