Abstract
The invention relates to a dual-deformation elastic nut comprising a column-shaped boss with an inner threaded through hole. The bottom face of the boss is fixedly provided with an elastic piece of an integral structure. The elastic piece comprises an upper elastic piece body and a lower elastic piece body, wherein the upper elastic piece body and the lower elastic piece body are arranged in an up-down mode, and the lower elastic piece body is horizontally arranged and provided with a first through hole. Due to split forming, the upper elastic piece body is respectively connected with a middle plate and a side plate, wherein the middle plate is arranged parallel to the lower elastic piece body, and the side plate is arranged in an inclined mode. The middle plate is provided with a second through hole, the upper surface of the middle plate is fixedly connected with the lower surface of the boss, the first end of the middle plate is connected with the first end of the side plate as a whole, the second end of the middle plate is separated from the side plate, the second end of the side plate is connected with one end of the lower elastic piece body after being bent downward, the connecting portion of the lower elastic piece body and the side plate is provided with a groove, and the tail end of the upper elastic piece body is provided with a tail portion bent upward. By means of the two-layer elastic piece structure, the two ends of the elastic piece are deformed at the same time, and accordingly shearing force and bending moment of the elastic piece on a screw are effectively reduced, the stress condition of the screw is improved, and service life is prolonged. The dual-deformation elastic nut has the advantages of being simple in structure, low in weight and firm in connection.
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 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 co-deflection 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 co-deflection nut with elastic, comprise the cylindrical end tangs with internal thread through hole, and the shell fragment of the affixed integrative-structure in bottom surface of boss, shell fragment comprise that upper shell fragment setting up and down reaches the horizontally disposed lower shell fragment with the first through hole; Upper shell fragment is by the cut moulding middle plate that be arranged in parallel with lower shell fragment respectively and the side plate that is obliquely installed, tabularium has the second through hole, its upper surface is fixedly connected with the lower surface of boss, 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, and the end of upper shell fragment has the upwards afterbody of bending.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, owing to adopting double-deck elastic piece structure, distortion in the time of by the shell fragment two ends, 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 cylindrical end tangs 4 with internal thread through hole 41, the shell fragment 1 of the affixed integrative-structure in bottom surface of boss 4, shell fragment 1 comprise the lower shell fragment 5 that upper shell fragment setting up and down 7 reaches with the first through hole 51, and lower shell fragment 5 is horizontally disposed with; Upper shell fragment 7 is by the cut moulding middle plate 2 that be arranged in parallel with lower shell fragment 5 respectively and the side plate 6 that is obliquely installed, middle plate 2 is with the second through hole 21, its upper surface is fixedly connected with the lower surface of boss 4, and the first end 61 of middle plate 2 one ends and side plate 6 connects as one, and the 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 bending and moldings of being convenient to shell fragment; The end of upper shell fragment 7 has the upwards afterbody 71 of bending, and the effect of afterbody 71 is while being adjacent to lower shell fragment 5 after upper shell fragment 7 is out of shape, to prevent that shell fragment 7 from fractureing, and reduces and the fretting wear of 5, lower shell fragment.
When the present invention installed, the fastening screw trip bolt (not shown) screwed in from the internal thread through hole 41 of cylindrical end tangs 4, and was connected with the connected piece (not shown) after passing successively the first through hole 51 of the second through hole 21 of middle plate 2 and lower shell fragment 5; When screw constantly screws, middle plate 2 can be out of shape downwards around the joint of itself and side plate 6, upper shell fragment 7 can be out of shape downwards around side plate 6 and the joint of lower shell fragment, finally make the upper surface of cylindrical end tangs 4 be in level, therefore the axis of screw finally overlaps with the axis of internal thread through hole 41, the first through hole 51 and the second through hole 21, thereby greatly reduced shearing force and moment of flexure that screw is subject to, 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.
