Abstract

The invention relates to an anti-loosening elastic sheet nut which comprises a circular truncated cone with an inner threaded through hole. The bottom face of the circular truncated cone is fixedly connected with a U-shaped elastic sheet. A groove is formed in the closed end of the U-shaped elastic sheet. The U-shaped elastic sheet comprises a lower elastic sheet horizontally arranged and an upper elastic sheet inclining upwards. The upper surface of the upper elastic sheet is fixedly connected with the bottom face of the circular truncated cone. The lower elastic sheet is provided with a first through hole. A second through hole is formed in the upper elastic sheet, wherein the size of the second through hole is identical to that of the inner threaded through hole. The axis of the second through hole coincides with that of the inner threaded through hole. The tail end of the upper elastic sheet is provided with a tail portion bent upwards. The upper surface of the circular truncated cone inclines upwards relative to the lower elastic sheet. Compared with an existing elastic sheet nut, the anti-loosening elastic sheet nut adopts the U-shaped elastic sheet structure and is provided with the circular truncated cone, so that the shearing force and the bending moment of the elastic sheet to a screw are effectively reduced, the force receiving condition of the screw is improved, the service life is prolonged, and the anti-loosening elastic sheet nut has the advantages of being simple in structure, light in weight and stable in connection.

Description

Locking nut with elastic
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 has the good characteristics of anti-loosing effect.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 locking 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 locking nut with elastic, comprise the taper round platform with internal thread through hole, the affixed analog-U shaped shell fragment in the bottom surface of round platform, and the closed end of analog-U shaped shell fragment has groove; Analog-U shaped shell fragment comprises horizontally disposed lower shell fragment and is tilted to the upper shell fragment of lower setting, and the upper surface of upper shell fragment and the bottom surface of round platform are affixed; Lower shell fragment has the first through hole, and upper shell fragment has and internal thread through hole the second through hole of the same size, the axis of the second through hole and the dead in line of internal thread through hole, and the end of upper shell fragment is with the afterbody of the bending that makes progress; The upper surface of round platform descends shell fragment to be tilted to setting relatively.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, owing to adopting analog-U shaped elastic piece structure, and be provided with the taper round platform of plane of inclination, effectively reduced shearing force and the moment of flexure of shell fragment to screw, improved the force-bearing situation of screw, extended working life, it has, and simple in structure, quality is light, the characteristics of stable connection.
Description of drawings
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, the present invention includes the taper round platform 2 with internal thread through hole 21, the affixed analog-U shaped shell fragment 1 in the bottom surface of round platform 2, the closed end of analog-U shaped shell fragment 1 has groove 11; Analog-U shaped shell fragment 1 comprises horizontally disposed lower shell fragment 4 and is tilted to the upper shell fragment 3 of lower setting, and the closed end height of analog-U shaped shell fragment 1 is greater than the height of its opening end; The bottom surface of the upper surface of upper shell fragment 3 and round platform 2 is affixed, lower shell fragment 4 has the first through hole 41, upper shell fragment 3 has and internal thread through hole 21 the second through hole 31 of the same size, the dead in line of the axis of the second through hole 31 and internal thread through hole 21, the end of upper shell fragment 3 is with the afterbody 32 of the bending that makes progress, the effect of afterbody 32 is when being adjacent to lower shell fragment 4 after 3 distortion of upper shell fragment, prevents that shell fragment 3 from fractureing, and reduces and the fretting wear of 4, lower shell fragment; The upper surface 22 of round platform 2 descends shell fragment 4 to be tilted to setting relatively.
when the present invention installs, the fastening screw trip bolt (not shown) screws in from the internal thread through hole 21 of taper round platform 2, and be connected with the connected piece (not shown) after passing successively the first through hole 41 of the second through hole 31 of shell fragment 3 and lower shell fragment 4, because having the upper surface 22 and the upper shell fragment 3 that are obliquely installed, taper round platform 2 is obliquely installed, when the opening end of analog-U shaped shell fragment 1 is drawn close when upper shell fragment 3 distortion, the upper surface 22 of taper round platform 2 is tending towards level gradually, this moment screw axis and internal thread through hole 21, the axis of the first through hole 41 and the second through hole 31 all overlaps, thereby shearing force and moment of flexure that screw is subject to have greatly been reduced, improved the force-bearing situation of screw.
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.
