Abstract
The invention relates to an elastic sheet of an arch structure. The elastic sheet of the arch structure comprises a circular body of a board-shaped structure. The body comprises transversely and symmetrically arranged arch portions and longitudinally and symmetrically arranged downward-recessed portions. The middle of the body is split and bent upwards so that elastic sheet bodies can be formed. The elastic sheet bodies are arranged in a laterally symmetric mode. The two sides of each elastic sheet body in the longitudinal direction are away from the body for a distance. The transverse side edges of each elastic sheet body are respectively provided with an arc-shaped groove. A through hole is formed between the arc-shaped grooves. Compared with an existing elastic sheet nut, the elastic sheet of the arch structure enables the body to be provided with the arch portions changeable in shape, the deformation of the symmetrically arranged elastic sheet bodies is even, so that large pre-tightening force is offered to a screw, the shearing force and the bending moment exerted on the screw are small, and the elastic sheet of the arch structure has the advantages of being simple in structure, long in service life, high in connection stability and convenient to machine.
Description
Technical field
The present invention relates to pad, relate in particular to resilient pad.
Background technique
The shell fragment of arch structure is the parts that prevent that the fastening pieces such as screw or nut are loosening.Generally with the structure of annular opening, its shortcoming is the force unbalance that is subjected to that makes between screw bolt and nut to the shell fragment of existing arch structure, causes the steadiness that connects poor.
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 shell fragment of the arch structure that improve the screw force-bearing situation, increase the service life.
The technical solution adopted in the present invention is as follows:
A kind of shell fragment of arch structure comprises that the circular body of platy structure, body comprise the arch portion that lateral symmetry is arranged and the lower dent that vertically is arranged symmetrically with; The middle part of body is through cutting backward upper bending forming shell fragment, and shell fragment is and is symmetrically arranged, and has spacing between vertical both sides of shell fragment and body; The transverse sides of shell fragment all has arc groove, forms through hole between arc groove.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, because body has deformable arch portion, and the deformation of symmetrical shell fragment is even, offer the larger pretightening force of screw, its shearing force and moment of flexure to screw is less, it has simple in structure, long service life, the high and characteristics easy to process of stable connection.
Description of drawings
Fig. 1 is three-dimensional structure diagram of the present invention.
Fig. 2 is main sectional view 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 circular body 1 of platy structure, body 1 comprises the arch portion 12 that lateral symmetry is arranged and the lower dent 11 that vertically is arranged symmetrically with; The middle part of body 1 is through cutting backward upper bending forming shell fragment 2, and shell fragment 2 is and is symmetrically arranged, and 1 of vertical both sides of shell fragment 2 and body have spacing 5, and spacing 5 is convenient to the bending and molding of shell fragment 2; The transverse sides of shell fragment 2 all has arc groove 3, and 3 of arc grooves form through hole 4, and the size of through hole 4 satisfies passing through of screw (bolt).
The present invention in use, the bolt (not shown) is connected with connected piece after passing through hole 4, because shell fragment 2 is symmetrically distributed on the body 1, its distortion evenly, and the arch portion 12 of body also produces deformation simultaneously, the two elastic force that provides has improved bolted reliability, can avoid shell fragment that bolt is produced shearing force simultaneously, improves the force-bearing situation of bolt, it has simple in structure, easy to process, long service life, the characteristics of stable connection.
More than describing is explanation of the invention, is not that limited range of the present invention is referring to claim to the restriction of invention, and in the situation of spirit of the present invention, the present invention can do any type of modification.
Claims (1)
1. the shell fragment of arch structure comprises the circular body (1) of platy structure, and it is characterized in that: described body (1) comprises the arch portion (12) that lateral symmetry is arranged and the lower dent (11) that vertically is arranged symmetrically with; The middle part of described body (1) is through cutting backward upper bending forming shell fragment (2), and described shell fragment (2) is and is symmetrically arranged, and has spacing (5) between vertical both sides of shell fragment (2) and body (1); The transverse sides of described shell fragment (2) all has arc groove (3), forms through hole (4) between described arc groove (3).
