Abstract
The utility model relates to an ached elastic gasket. The arched elastic gasket comprises a body of a plate-shaped structure, wherein the body is an arched structure; the middle part of the arched structure is cut and then upwards bent to form elastic sheets which are symmetrically arranged; a groove is respectively arranged at one side of each of the elastic sheets; through holes are formed among the grooves. Compared with the existing elastic sheet nut, the body is arched, and the symmetrically distributed elastic sheets are uniform in shape change to provide greater pre-tightening force to bolts, and therefore, shearing force as well as bending moment to bolts is smaller. Besides, the arched elastic sheet has characteristics of being simple in structure, long in service life and high in connecting stability.
Description
Technical field
The utility model relates to pad, relates in particular to resilient pad.
Background technique
Arched elastic pad is to prevent the loosening parts of fastening piece such as screw or nut.Existing arched elastic pad is generally with the structure of annular opening, and its shortcoming is the force unbalance that is subject to making between screw bolt and nut, causes the steadiness of connection poor.
Model utility content
The applicant, for the above-mentioned shortcoming of prior art, studies and improves, and provides a kind of simple in structure, the arched elastic pad that improve screw force-bearing situation, increases the service life.
The technological scheme that the utility model adopts is as follows:
A pad, comprises the body of platy structure, and body is arch shape structure, and the shell fragment that its middle part is arranged symmetrically with through cutting backward upper bending forming, one side shell fragment all has a groove, forms through hole between groove.
The beneficial effects of the utility model are as follows:
The more existing nut with elastic of the utility model, because body is arch shape, and the deformation of symmetrical shell fragment is even, offer the pretightening force that screw is larger, it is less to the shearing force of screw and moment of flexure, and it has simple in structure, long service life, the feature that stable connection is high.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is main sectional view 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 body 1 of platy structure, and body 1 is arch shape structure, the shell fragment 2 that its middle part is arranged symmetrically with through cutting backward upper bending forming, one side of shell fragment 2 all has groove 3, and 3 of grooves form through hole 4, and the size of through hole 4 meets passing of screw (bolt).
The utility model in use, bolt (not shown) is connected with connected piece through through hole 4 is rear, because shell fragment 2 is symmetrically distributed on body 1, its distortion is even, and the body of arch shape structure also produces deformation simultaneously, the two elastic force providing has improved bolted reliability, can avoid shell fragment to produce shearing force to bolt, improve the force-bearing situation of bolt, it has simple in structure simultaneously, long service life, the feature of stable connection.
More than describing 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, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
