Abstract
The utility model relates to an elastic piece nut which comprises a nut; the upper surface of the nut is fixedly connected with an elastic piece; the elastic piece has a plate-shaped square structure provided with a through hole in the center; the axis of the through hole is coincided with that of a thread through hole of the nut; the left end and right end of the elastic piece are bent downwards, so that two side baffles can be formed; the tail ends of the side baffles are bent towards the center of the nut, so that hook parts can be formed; the front end and rear end of the elastic piece are bent downwards, so that an enveloping part can be formed; the enveloping part clings to the outer side wall of the nut. Compared with the existing elastic piece nut, the elastic piece nut is smaller in shear force and bending moment for a screw since the deformation of the elastic piece is even and a larger pre-tightening force is provided for the screw; the elastic piece nut has the characteristics of being simple in structure, long in service life and high in connection stability.
Description
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 that improve screw force-bearing situation, increases the service life.
The technological scheme that the utility model adopts is as follows:
, comprise nut, the affixed shell fragment of upper surface of nut, centered by shell fragment with the tabular square structure of through hole, the dead in line of the axis of through hole and the tapped through hole of nut; Two ends, the left and right downward bending moulding lateral retaining plate of shell fragment, the end of lateral retaining plate is to the bending and molding hook part, center of nut; The rear and front end downward bending moulding envelope portion of shell fragment, envelope portion is near the outer side wall of nut.
The beneficial effects of the utility model are as follows:
The more existing nut with elastic of the utility model, because the deformation of shell fragment is even, offers the pretightening force that screw is larger, and it is less to the shearing force of screw and moment of flexure, and it has simple in structure, long service life, the feature that stable connection is high.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present utility model.
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, a kind of nut with elastic of the utility model, comprises nut 2, the affixed shell fragment 1 of upper surface of nut 2, centered by shell fragment 1 with the tabular square structure of through hole 11, the dead in line of the tapped through hole 21 of the axis of through hole 11 and nut 2; Two ends, the left and right downward bending moulding lateral retaining plate 12 of shell fragment 1, the end of lateral retaining plate 12 is to the bending and molding hook part, center 13 of nut 2; The rear and front end downward bending moulding envelope portion 14 of shell fragment 1, envelope portion 14 is near the outer side wall of nut 2, and envelope portion 14 is for improving and the connection reliability of shell fragment 1 with nut 2.
During the utility model work, after bolt (not shown) screws, the hook part 13 of shell fragment 1 produces deformation, thereby offer the elastic force that nut 2 is larger, because hook part 13 is symmetrically distributed in the both sides of shell fragment 1, its distortion evenly, avoids bolt to be subject to shearing force and moment of flexure, thereby increase the service life, improve 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.
