Abstract
The utility model discloses a kind of anti-loose pad, comprise shim body, the upper and lower end of this shim body is equipped with a groove, in the middle of shim body, it is a through hole, between groove mouth place and shim body, be provided with an inclined-plane, each groove middle is all placed with a briquetting, and the lower end of this briquetting is provided with more than one spring, described spring lays respectively at the both sides of through hole, each one of every side; The utility model in use, nut is stuck in groove, now briquetting is stressed toward pressing down, after meeting spring, be obstructed, spring, to rebounding force of briquetting, increases the power between nut and pad, the inclined-plane at groove mouth place can play the effect of clamping nut, and then greatly increase large stretch of anti-loose ability, and reduce the generation of peril, increase service life of equipment.
Description
Technical field
The utility model relates to a kind of anti-loose pad.
Background technique
Pad is a kind of anti-loose fastening piece, is conventionally placed on nut lower end, but traditional pad is solid construction, between pad and nut, can only lean on screwing force fastening, therefore, the vibrations that equipment produces in use can cause the loosening of nut, and the equipment that affects normally uses.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-loose ability that can greatly increase sheet, reduces the generation of peril, increases the anti-loose pad of service life of equipment.
The utility model is achieved through the following technical solutions: a kind of anti-loose pad, comprise shim body, the upper and lower end of this shim body is equipped with a groove, in the middle of shim body, it is a through hole, between groove mouth place and shim body, be provided with an inclined-plane, each groove middle is all placed with a briquetting, and the lower end of this briquetting is provided with more than one spring, described spring lays respectively at the both sides of through hole, each one of every side.
As preferred technological scheme, described groove is " Y " type, and the upper and lower end of shim body is equipped with one " Y " type groove.
As preferred technological scheme, described briquetting is made up of the higher metallic material of hardness.
As preferred technological scheme, the maximum diameter of described groove is less than the diameter of shim body.
As preferred technological scheme, between described spring upper end and briquetting, be fixedly connected by welding, between the lower end of spring and shim body, be fixedly connected by welding.
The beneficial effects of the utility model are: the utility model in use, nut is stuck in groove, now briquetting is stressed toward pressing down, after meeting spring, be obstructed, spring, to rebounding force of briquetting, increases the power between nut and pad, the inclined-plane at groove mouth place can play the effect of clamping nut, and then greatly increase large stretch of anti-loose ability, and reduce the generation of peril, increase service life of equipment.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the anti-loose pad of one of the present utility model, comprise shim body 1, the upper and lower end of this shim body 1 is equipped with a groove 5, in the middle of shim body 1, is a through hole 2, is provided with an inclined-plane 6 between groove mouth place and shim body 1, each groove 5 middles are all placed with a briquetting 3, the lower end of this briquetting 3 is provided with more than one spring 4, and described spring 4 lays respectively at the both sides of through hole 2, each one of every side.
As preferred technological scheme, described groove 5 is " Y " type, and the upper and lower end of this 1 body of pad is equipped with one " Y " type groove.
As preferred technological scheme, described briquetting 3 is made up of the higher metallic material of hardness.
As preferred technological scheme, the maximum diameter of described groove 5 is less than the diameter of shim body 1.
As preferred technological scheme, between described spring 4 upper ends and briquetting 3, be fixedly connected by welding, between the lower end of spring 4 and shim body 1, be fixedly connected by welding.
The beneficial effects of the utility model are: the utility model in use, nut is stuck in groove, now briquetting is stressed toward pressing down, after meeting spring, be obstructed, spring, to rebounding force of briquetting, increases the power between nut and pad, the inclined-plane at groove mouth place can play the effect of clamping nut, and then greatly increase large stretch of anti-loose ability, and reduce the generation of peril, increase service life of equipment.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
