Abstract
The invention relates to an elastic piece nut which comprises a nut body. The upper surface of the nut body is fixedly connected with an elastic piece, the elastic piece is of a platy square structure, a through hole is formed in the center of the elastic piece, the axis of the through hole coincides with the axis of a threaded through hole of the nut body, the left end and the right end of the elastic piece are bent downwards to form side baffles, and the tail ends of the side baffles are bent towards the center of the nut body to form hook parts. The front end and the back end of the elastic piece are bent downwards to form an enveloping part which tightly abuts against the outer side walls of the nut body. Compared with an existing elastic piece nut, due to the fact that the deformation of the elastic piece is uniform, large pretightening force is supplied to screws, the shear force and the bending torque of the elastic piece nut to the screws are small, and the elastic piece nut has the advantages of being simple in structure, long in service life, and high in connecting stability.
Description
Technical field
The present invention relates to a kind of nut, relate 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, have the advantages that anti-loosing effect is good.When nut with elastic 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 the anti-loosening locking effect.Although this nut can play certain locking effect, due to the continuous distortion of shell fragment, make shearing force and the moment of flexure that screw is subject to increase, cause screw to go fastening effect because of distortion.
Summary of the invention
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 the screw force-bearing situation, increases the service life.
The technical solution adopted in the present invention is as follows:
A kind of nut with elastic, comprise nut, the affixed shell fragment of the 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 section of shell fragment, envelope section is near the outer side wall of nut.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, because the deformation of shell fragment is even, offer the pretightening force that screw is larger, and its shearing force to screw and moment of flexure are less, and it has simple in structure, long service life, the characteristics that stable connection is high.
The accompanying drawing explanation
Fig. 1 is main sectional view of the present invention.
Fig. 2 is three-dimensional structure diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1 and Fig. 2, a kind of nut with elastic of the present invention, comprise nut 2, the affixed shell fragment 1 of the 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 section 14 of shell fragment 1, envelope section 14 are near the outer side wall of nut 2, and envelope section 14 is for improving and the connection reliability of shell fragment 1 with nut 2.
When the present invention works, after the bolt (not shown) screws, the hook part 13 of shell fragment 1 produces deformation, thereby offer the elastic force that nut 2 is larger, due to hook part 13, be 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 that connects.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to spirit of the present invention, the present invention can do any type of modification to the restriction of invention.
