Abstract
The invention relates to a pre-tensioning elastic piece with auxiliary plates. The pre-tensioning elastic piece with the auxiliary plates comprises a base board provided with a first conical through hole. The lower surface of the base board is fixedly connected with a boss of a cylindrical structure. The boss is provided with a second conical through hole, wherein the central axis of the first conical through hole coincides with that of the second conical through hole. The left end and the right end of the base board extend respectively and then bend downwards to form elastic piece bodies which are symmetric with each other. Each elastic piece body comprises a bending part which bends inwards, wherein the tail end of the bending part bends outwards to form a hook part, and a certain distance is reserved between the hook parts. The front end and the rear end of the base board extend respectively to from the auxiliary plates of a swallow tail structure, and grooves are formed in the joints of the auxiliary plates and the base board. Compared with an existing elastic piece nut, the pre-tensioning elastic piece with the auxiliary plates has the advantages that due to the adoption of the elastic piece bodies provided with the hook parts and the arrangement of the bendable auxiliary plates, when a screw is tightened, the elastic piece bodies, the hook parts of the elastic piece bodies and the auxiliary plates deform together, large elastic force is provided for the screw, and the connection stability is improved.
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 the 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, because the continuous distortion of shell fragment so that the shearing force that screw is subject to and moment of flexure increase, causes screw to go fastening effect because of distortion.
Summary of the invention
The applicant studies and improves for the above-mentioned shortcoming of prior art, provides a kind of simple in structure, the pretension shell fragment with auxiliary plate 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 pretension shell fragment with auxiliary plate comprises the seat board with the first conical through-hole, the boss of the affixed column construction of lower surface of seat board, and boss has the second conical through-hole, the central axes setting of the central axis of the first conical through-hole and the second conical through-hole; The symmetrical shell fragment of backward lower bending and molding is extended respectively at the two ends, the left and right sides of seat board, and shell fragment has the bending part of inside bending, and the terminal outward moulding hook part of bending part has certain spacing between the hook part; The rear and front end of seat board extends to form respectively the auxiliary plate of dovetail structure, and the joint of auxiliary plate and seat board has groove.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, but owing to adopting with the shell fragment of hook part and the auxiliary plate of setting bending, when screw screwed, shell fragment and its hook part and auxiliary plate were out of shape jointly, offered the larger elastic force of screw, thus improved the steadiness that connects.
Description of drawings
Fig. 1 three-dimensional structure diagram of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
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 seat board 1 with the first conical through-hole 11, the boss 6 of the affixed column construction of lower surface of seat board 1, boss 6 have the central axes setting of central axis and second conical through-hole 61 of the second conical through-hole 61, the first conical through-holes 11; The symmetrical shell fragment 2 of backward lower bending and molding is extended respectively at the two ends, the left and right sides of seat board 1, shell fragment 2 has the bending part 21 of inside bending, the terminal outward moulding hook part 22 of bending part 21,22 of hook parts have certain spacing 5, and the width of spacing 5 satisfies passing through of screw; The rear and front end of seat board 1 extends to form respectively the auxiliary plate 3 of dovetail structure, auxiliary plate 3 has groove 4 with the joint of seat board, the effect of auxiliary plate 3 is to carry out downward bending by groove 4 places and to form dunnage according to the size of fastening screw trip bolt (not shown), to improve the steadiness that connects.
When the present invention installs, according to the size of fastening screw trip bolt (not shown), with the certain angle of auxiliary plate 3 downward bendings; Fastening screw trip bolt screws in from the first conical through-hole 11 of seat board 1, and is connected with the connected piece (not shown) after passing successively the spacing 5 of 21 of hook parts of the second conical through-hole 61 of boss 6 and shell fragment 2; When screw constantly screws, the hook part 21 of shell fragment 2 is around joint downwards distortion and the hook part 21 generation distortion own of seat board 1 with shell fragment 2, auxiliary plate 3 with also produce distortion after connected piece contacts, thereby so that whole shell fragment produces larger elastic force, so that the increase of the coupling mechanism force of screw, thereby improved 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.
