Abstract

The utility model discloses an anti-slide screw and an anti-slide tray which are formed by processing the prior screw and the tray. Based on the prior screw, one surface of the screw is processed again, so that small shallow pits of uniform sizes are distributed on the surface. Based on the prior tray, the two faces of the tray are processed again, so that S-shaped lines are distributed on one surface of the tray, and small salient points are distributed on the other surface of the tray. With the improved structure based on the prior technology, the shallow pits on one surface of the screw are matched with the salient points on one surface of the tray to effectively prevent the screw from disengaging with a bolt and to avoid inconvenient operation and danger.

Description

Anti-skidding screw and pad

One, affiliated technical field

The utility model relates to a kind of anti-skidding screw and pad.

Two, background technique

At present, screw and pad thereof commonly used can not prevent effectively that screw from coming off from bolt, some screws and pad only carried out reprocessing to screw makes it possess anti-slip function, pad is this function not then, make skidproof effect not obvious, in use screw often comes off from bolt, causes a lot of inconvenience and easy initiation potential to people's life.

Three, model utility content

The purpose of this utility model is to provide a kind of anti-skidding screw and pad.

For achieving the above object, the solution that the utility model is taked is:

A kind of anti-skidding screw, it is on original screw basis, and the wherein one side of screw is reprocessed, and makes it be covered with the unified little shallow hole of size.

A kind of anti-skidding screw washer, it is on original screw washer basis, and the two sides of pad is reprocessed, and makes the lines that wherein simultaneously is covered with S shape, one side is covered with small salient point in addition.

After the utility model improves existing technology, when using anti-skidding screw and pad, the shallow hole of screw one side and the salient point of pad one side are suited, can prevent effectively that screw from coming off from bolt, avoid the inconvenience and the initiation potential that use.
