Abstract

The utility model relates to a simple locking gasket. The simple locking gasket comprises a shrapnel body which is a plate-shaped structure, wherein the body is of a square structure, and the center of the body is provided with a through hole; the body is provided with a plurality of U-shaped grooves which are arranged symmetrically relative to the center of the through hole, the U-shaped grooves are communicated with the through hole, and the body part arranged between the adjacent U-shaped grooves which are bent upwards relative to the upper surface of the body so as to form elastic plates. Compared with the existing the shrapnel nut, the elastic plates are symmetrically arranged on the body, the large pretightening force is provided for a screw through the uniform deformation, the shear force and bending moment of the screw are small, the simple locking gasket provided by the utility model has the characteristics that the structure is simple, the service life is long, the installation is convenient, the stability of the connection is high, and the process is convenient.

Description

Simple and easy check washer

Technical field

The utility model relates to pad, relates in particular to resilient pad.

Background technique

Simple and easy check washer is to prevent the loosening parts of fastening piece such as screw or nut.Existing simple and easy check washer 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 simple and easy check washer that improve screw force-bearing situation, increases the service life.

The technological scheme that the utility model adopts is as follows:

A kind of simple and easy check washer, the elastic sheet body that comprises platy structure, the square-shaped structure of body, its center is with through hole, on body, there is the U-shaped groove that a plurality of Central Symmetries about through hole are arranged, U-shaped groove is communicated with through hole, the upper surface of the relative body of body portion between the adjacent U-shaped groove bending and molding elastic plate that makes progress.

The beneficial effects of the utility model are as follows:

The more existing nut with elastic of the utility model, because elastic plate is symmetrically distributed on body, its deformation 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 easy for installation, stable connection is high and easy to process.

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 elastic sheet body 1 of platy structure, it is characterized in that: the square-shaped structure of body 1, its center is with through hole 4, on body 1, there is the U-shaped groove 3 that a plurality of Central Symmetries about through hole 4 are arranged, U-shaped groove 3 is communicated with through hole 4, the upper surface of the relative body 1 of body portion between the adjacent U-shaped groove 3 bending and molding elastic plate 2 that makes progress, and relative body 1 Central Symmetry of elastic plate 2 distributes.

The utility model in use, bolt (not shown) is connected with connected piece through through hole 4 is rear, because elastic plate 2 is symmetrically distributed on body 1, evenly, the elastic force of its generation has improved bolted reliability in its distortion, can avoid shell fragment to produce shearing force to bolt simultaneously, the force-bearing situation that improves bolt, it has simple in structure, easy for installation, 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.

Claims

1. a simple and easy check washer, the elastic sheet body (1) that comprises platy structure, it is characterized in that: the square-shaped structure of described body (1), its center is with through hole (4), on body (1), there is the U-shaped groove (3) that a plurality of Central Symmetries about described through hole (4) are arranged, described U-shaped groove (3) is communicated with described through hole (4), the upper surface of the relative body of body portion (1) between adjacent U-shaped groove (3) the bending and molding elastic plate (2) that makes progress.
