Abstract
The invention relates to an inwards concaved type elastic gasket. The inwards concaved type elastic gasket comprises a body of a round structure, wherein a through hole is formed in the center of the body, a plurality of elastic pieces inclined towards the lower side of the body are arranged in the middle of the body, each elastic piece is in an arc structure, the elastic pieces are arranged in a central symmetry mode relative to the center of the body, a U-shaped concave groove is formed between every two adjacent elastic pieces, and an annular flange is arranged on the periphery of the lower surface of the body. Compared with an existing elastic piece nut, due to the fact that the deformation of the symmetrically arranged elastic pieces is uniform, large pre-tightening force is provided for a screw, the shearing force and bending moment of the inwards concaved type elastic gasket on the screw are small, and the inwards concaved type elastic gasket has the advantages of being simple in structure, long in service life and high in connecting firmness.
Description
Technical field
The present invention relates to pad, relate in particular to resilient pad.
Background technique
The inner concave shape resilient pad is the part that prevents that the fastening pieces such as screw or nut are loosening.Existing inner concave shape resilient pad is generally with the structure of annular opening, and its shortcoming is the force unbalance that is subjected to that makes between screw bolt and nut, causes the steadiness that connects poor.
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 inner concave shape resilient pad 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 inner concave shape resilient pad, comprise the body of center with the round structure of through hole, and the middle part of body has a plurality of shell fragments that tilt towards the body downside; Shell fragment has the arc shape structure, and the center of circle of its relative body layout that is centrosymmetric, have U-shaped groove between adjacent shell fragment; The lower surface periphery of body has annular flange flange.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention,, because the deformation of symmetrical shell fragment is even, offer the larger pretightening force of screw, and its shearing force to screw and moment of flexure are less, and it has simple in structure, long service life, the characteristics that stable connection is high.
Description of drawings
Fig. 1 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 body 1 of center with the round structure of through hole 4, the middle part of body 1 has a plurality of shell fragments 2 that tilt towards the body downside, and shell fragment 2 has the arc shape structure, the center of circle of its relative body 1 layout that is centrosymmetric, 2, adjacent shell fragment has U-shaped groove 3; The lower surface periphery of body 1 has annular flange flange 5.
The present invention in use, the bolt (not shown) is connected with connected piece after passing through hole 4, because shell fragment 2 is uniformly distributed on body 1, its distortion evenly, provides elastic force to improve bolted reliability, can avoid former shell fragment to produce shearing force to bolt simultaneously, improve the force-bearing situation of bolt, it has simple in structure, long service life, the characteristics of stable connection.
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.
Claims (1)
1. inner concave shape resilient pad, comprise the body (1) of center with the round structure of through hole (4), it is characterized in that: the middle part of described body (1) has a plurality of shell fragments (2) that tilt towards body (1) downside, described shell fragment (2) has the arc shape structure, the center of circle of its relative body (1) layout that is centrosymmetric, have U-shaped groove (3) between described adjacent shell fragment (2); The lower surface periphery of described body (1) has annular flange flange (5).
