Abstract

The utility model relates to a resilient sheet nut with a circular platform. The resilient sheet nut comprises a resilient sheet which is placed horizontally and is in a similar U-shaped structure, wherein the resilient sheet comprises a horizontally placed upper resilient sheet and a lower resilient sheet which is arranged obliquely and upwards relative to the upper resilient sheet; the upper resilient sheet is provided with a first through hole and the upper surface of the upper resilient sheet is fixedly connected with a columnar lug boss; the lug boss is provided with a threaded through hole; a rib plate is arranged between the upper surface of the upper resilient sheet and the side wall of the lug boss; the upper surface of the lower resilient sheet is fixedly connected with a circular platform with a conical structure; the circular platform is provided with a second through hole. Compared with an existing resilient sheet nut, with the adoption of the obliquely-arranged lower resilient sheet, when a screw is screwed up, the resilient sheet deforms so as to provide a great pre-tightening force to the screw and a shearing force and a bending moment to the screw are small, and furthermore, the service life is prolonged and the connection stability is improved.

Description

Nut with elastic with round platform

Technical field

The utility model relates to a kind of nut, relates in particular to nut with elastic.

Background technique

Nut is to be applied to the most frequently used part that mechanical structure is fastenedly connected.Nut with elastic is a kind of novel nut, and more common nut, has the advantages that anti-loosing effect is good.When nut with elastic is used, the shell fragment on nut can produce deformation, and along with the impacting force of nut is larger, the elastic force of shell fragment is also larger, thereby plays anti-loosening locking effect.Although this nut can play certain locking effect, due to the continuous distortion of shell fragment, shearing force and moment of flexure that screw is subject to are increased, cause screw to go fastening effect because of distortion.

Model utility content

The applicant, for the above-mentioned shortcoming of prior art, studies and improves, and provides a kind of simple in structure, the nut with elastic with round platform that improve screw force-bearing situation, increases the service life.

The technological scheme that the utility model adopts is as follows:

A kind of nut with elastic with round platform, the shell fragment that comprises the analog-U shaped structure of horizontal, shell fragment comprises the upper shell fragment of horizontal positioned and relatively goes up the lower shell fragment that shell fragment is tilted to setting, upper shell fragment has the first through hole, the affixed cylindrical end tangs of its upper surface, boss is threaded through hole, between the upper surface of upper shell fragment and the sidewall of boss, has floor; The round platform of the affixed cone structure of upper surface of lower shell fragment, round platform is with the second through hole.

The beneficial effects of the utility model are as follows:

The more existing nut with elastic of the utility model, by the lower shell fragment being obliquely installed, when screw screws, shell fragment deforms, and offers the pretightening force that screw is larger, and it is less to the shearing force of screw and moment of flexure, thereby extended working life, improved the steadiness connecting.

Accompanying drawing explanation

Fig. 2 is three-dimensional structure diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

See Fig. 1 and Fig. 2, the utility model comprises the shell fragment of the analog-U shaped structure of horizontal, shell fragment comprises the upper shell fragment 2 of horizontal positioned and relatively goes up the lower shell fragment 3 that shell fragment 2 is tilted to setting, upper shell fragment 2 has the first through hole 21, the affixed cylindrical end tangs 1 of its upper surface, boss 1 is threaded through hole 11, between the sidewall of the upper surface of upper shell fragment 2 and boss 1, has floor 5; The round platform 4 of the affixed cone structure of upper surface of lower shell fragment 3, round platform 4 is with the second through hole 41.

When the utility model is installed, fastening screw trip bolt screws in from the tapped through hole 11 of cylindrical end tangs 1, and successively through the first through hole 21 of upper shell fragment 2 and the second through hole 41 of lower shell fragment 3, when screw constantly screws, lower shell fragment 3 deforms, after distortion, be tending towards gradually level, thereby the axis of screw overlaps respectively with the axis of tapped through hole 11, the first through hole 21, the second through hole 41, shearing force and moment of flexure that screw is subject to have effectively been reduced, extend the working life of screw, and improved the steadiness connecting.

More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
