Description
Technical field:
The utility model relates to spring technical field, relates in particular to shock-proof spring device bearing.
Background technique:
For adapting to irregular road conditions and hole, hole, in most of bicycle, be all equiped with shock absorber, rock, beat to reduce vehicle body, to avoid bicycle associated components not because vibrations cause damage, and increase the travelling comfort that user takes.For shock absorber, spring is one of main anti-vibration component, utilizes the dilatation amount after spring stress, absorbs the vibrations of the middle bicycle that travels.Because spring is made the curved surface that rear two ends are all spirals, to contact at the two ends that spring when shock absorber is installed with shock absorber pedestal, lifting surface area is little, the easy scratch of surface of contact, so spring all needs two ends to polish before installation, but the length of spring is all long, entirety is with flexible, easy processing distortion, grinding precision is difficult to control, and is difficult to ensure the planeness of end face and is difficult to ensure that end face is vertical with axle center, in use easily causes surface of contact scratch and wearing and tearing, and the abrasive machining complex procedures of spring end, efficiency is low.
Model utility content:
The purpose of this utility model is exactly the deficiency existing for prior art and a kind of shock-proof spring device bearing that makes spring end face not need just to polish can to ensure spring normal mounting, simplify working process, raise the efficiency is provided.
To achieve these goals, the technical solution adopted in the utility model is:
Shock-proof spring device bearing, includes bearing body, and the upper-end surface of bearing body is convex is provided with circular projection, and the upper-end surface of bearing body is convex is provided with spiral winding and is located at the screw inclined plane of projection circumferential exterior surface.
The lower end surface of described bearing body is vertical with the axle center of projection.
The spiral number of turns of described screw inclined plane is 0.5～1 circle.
The height of described screw inclined plane is 1/4～1/2 of projection height.
Between described projection and bearing body, form inverted T-shaped platform structure.
The utility model beneficial effect is: the utility model includes bearing body, the upper-end surface of bearing body is convex is provided with circular projection, the upper-end surface of bearing body is convex is provided with spiral winding and is located at the screw inclined plane of projection circumferential exterior surface, when use, projection of the present utility model is plugged in the end of shock-proof spring, the two ends of shock-proof spring are supported and are installed on shock absorber pedestal by bearing of the present utility model, forming surface between bearing and shock absorber pedestal is contacted, after making shock-proof spring be installed in bearing, the spiral camber end of shock-proof spring can match and contact forming surface contact with screw inclined plane simultaneously, lifting surface area is large, avoid surface of contact scratch wearing and tearing, do not need to polish spring end face and just can ensure the installation perpendicularity of spring, simplify working process, raise the efficiency, processing and installation precision are high.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is installed to the structural representation on shock-proof spring.
Embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail, see shown in Fig. 1～2, the utility model includes bearing body 1, the upper-end surface of bearing body 1 is convex is provided with circular projection 11, and the upper-end surface of bearing body 1 is convex is provided with spiral winding and is located at the screw inclined plane 12 of projection 11 circumferential exterior surface.
The lower end surface of bearing body 1 is vertical with the axle center of projection 11, ensures the installation perpendicularity of shock-proof spring 2.Between projection 11 and bearing body 1, form inverted T-shaped platform structure, bearing structure are more steady.The spiral number of turns of screw inclined plane 12 is 0.5～1 circle, and the area of contact between spiral camber end and the screw inclined plane 12 of increase shock-proof spring 2 is stressed more balanced.The height of screw inclined plane 12 is 1/4～1/2 of projection 11 height, makes between projection 11 and shock-proof spring 2 in conjunction with more firm.
When use, projection 11 of the present utility model is plugged in the end of shock-proof spring 2, the two ends of shock-proof spring 2 are supported and are installed on shock absorber pedestal by bearing of the present utility model, forming surface between bearing and shock absorber pedestal is contacted, after making shock-proof spring 2 be installed in bearing, the spiral camber end of shock-proof spring 2 can match and contact forming surface contact with screw inclined plane 12 simultaneously, lifting surface area is large, avoid surface of contact scratch wearing and tearing, do not need to polish spring end face and just can ensure the installation perpendicularity of spring, simplify working process, raise the efficiency, processing and installation precision are high
Certainly, the above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
