Abstract
The utility model relates to an elastic piece type tightening nut. The elastic piece type tightening nut comprises a conical circular truncated cone with an inner threaded through hole, wherein the bottom surface of the circular truncated cone is fixedly connected with an elastic piece of an integrated structure, the elastic piece comprises a vertically arranged upper elastic piece and a horizontally arranged lower elastic piece, the lower elastic piece is provided with a first through hole, the upper surface of the circular truncated cone is aslant arranged relative to the lower elastic piece, the upper elastic piece comprises a horizontally arranged middle plate and an aslant arranged lateral plate, the middle plate is provided with a second through hole, the surface of the middle plate is fixedly connected with the lower surface of the circular truncated cone, a first end of the middle plate and a first end of the lateral plate are connected into a whole, a second end of the middle plate is separated from the lateral plate, a second end of the lateral plate is bent downwards and then is connected with one end of the lower elastic piece, and a concave groove is formed in the connecting position of the lower elastic piece and the lateral plate. Compared with an existing elastic piece type tightening nut, due to the facts that the elastic piece type tightening nut adopts a double-layer elastic piece structure and is provided with the conical circular truncated cone with the inclined plane, the shearing force and bending moment of the elastic piece on a screw are effectively lowered, the stress situation of the screw is improved, and the service life is prolonged. The elastic piece type tightening nut has the advantages of being simple in structure, light in weight and firm in connection.
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, have 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 the anti-loosening locking effect.Although this nut can play certain locking effect, due to the continuous distortion of shell fragment, the shearing force that makes screw be subject to and moment of flexure increase, and cause screw to go fastening effect because of distortion.
The model utility content
The applicant, for the above-mentioned shortcoming of prior art, is studied and is improved, and provides a kind of simple in structure, the spring-piece type tightening nut that improve the screw force-bearing situation, increases the service life.
The technological scheme that the utility model adopts is as follows:
A kind of spring-piece type tightening nut, comprise the taper round platform with internal thread through hole, the shell fragment of the affixed integrative-structure in bottom surface of round platform, shell fragment comprises that upper shell fragment setting up and down reaches the horizontally disposed lower shell fragment with the first through hole, the upper surface of round platform descends shell fragment to be obliquely installed relatively; Upper shell fragment is by the side plate of cutting the horizontally disposed middle plate of moulding and being obliquely installed, and tabularium has the second through hole, and its upper surface is fixedly connected with the lower surface of round platform, and the first end of middle plate and the first end of side plate connect as one, and its second end separates with side plate; An end that connects lower shell fragment after the second end downward bending of side plate; The joint of lower shell fragment and side plate has groove.
The beneficial effects of the utility model are as follows:
The more existing nut with elastic of the utility model, owing to adopting double-deck 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.
The 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, the utility model comprises the taper round platform 4 with internal thread through hole 41, the shell fragment 1 of the affixed integrative-structure in bottom surface of round platform 4, shell fragment 1 comprises the lower shell fragment 5 that upper shell fragment setting up and down 7 reaches with the first through hole 51, lower shell fragment 5 is horizontally disposed with, and the upper surface 42 of round platform 4 descends shell fragment 5 to be obliquely installed relatively; The side plate 6 that upper shell fragment 7 is horizontally disposed with middle plate 2 and is obliquely installed by cutting moulding, middle plate 2 is with the second through hole 21, its upper surface is fixedly connected with the lower surface of round platform 4, and an end of middle plate 2 and the first end 61 of side plate 6 connect as one, and its other end separates with side plate 6; An end that connects lower shell fragment 5 after the second end 62 downward bendings of side plate 6; Lower shell fragment 5 has groove 3 with the joint of side plate 6, and the effect of groove 3 is the bending and moldings that facilitate shell fragment.
When the utility model is installed, the fastening screw trip bolt (not shown) screws in from the internal thread through hole 41 of taper round platform 4, and through the second through hole 21 of middle plate 2 and the first through hole 51 of lower shell fragment 5, with the connected piece (not shown), be connected afterwards successively, because taper round platform 2 has the upper surface 22 that is obliquely installed and the side plate 6 of upper shell fragment 7 is obliquely installed, when upper shell fragment 7 is out of shape due to screwing of screw, in, the second end 23 of plate 2 is drawn close lower shell fragment 5, make the upper surface 42 of taper round platform 4 be tending towards gradually level, the now axis of screw and internal thread through hole 41, the axis of the first through hole 51 and the second through hole 21 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 to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range is referring to claim, in the situation that, without prejudice to spirit of the present utility model, the utility model can be done any type of modification.
