Abstract

The utility model discloses a rubber shock pad, be provided with the shock pad body of axial through-hole including the center, the shock pad body include the lower part the base and set up in the spiral part on base upper portion, the spiral part with the base junction be provided with the locking portion of coil spring one end butt. The upper part of the rubber shock pad body is arranged into the spiral part, when the rubber shock pad body is connected with the spiral spring, the shock absorption stability can be increased, the shock absorption effect is enhanced, and abnormal sound is eliminated, so that the service life of the shock pad is prolonged; the anti-slip groove is formed in the base of the shock pad, so that the friction force of a contact surface is increased, the sliding is reduced, the motion abrasion is reduced, abnormal sound can be eliminated, the service life is prolonged, and the shock pad is safe and reliable.

Description

Rubber shock pad

Technical Field

The utility model relates to a shock attenuation technical field especially relates to a rubber shock pad.

Background

The spring shock pad of the automobile is mainly used for buffering vertical pressure generated in the up-and-down jumping process of a spring, and in the actual use process, the shock pad in the market is mostly designed in a plane, so that the shock absorption performance is low; and the shock pad has abnormal sound in the use, and wearing and tearing are serious, and life is lower.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rubber shock pad to above-mentioned prior art not enough.

In order to solve the above problems, the utility model adopts the following technical proposal:

the utility model provides a rubber shock pad, includes that the center is provided with axial through hole's shock pad body, the shock pad body include the lower part the base and set up in the screw portion on base upper portion, the screw portion with the base junction is provided with the locking portion with coil spring one end butt.

Furthermore, the inner diameter of the through hole in the upper part of the shock pad body is smaller than that of the through hole in the lower part of the shock pad body.

Furthermore, the bottom wall of the shock pad body is provided with anti-skidding lines.

Furthermore, a plurality of anti-skidding grooves which are uniformly distributed along the radial direction of the through hole are formed in the bottom wall of the shock pad body.

Furthermore, the inner end of the anti-skid groove extends into the through hole and is axially and uniformly distributed along the inner wall of the through hole.

Further, the base and the spiral part are integrally formed.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:

the upper part of the rubber shock pad body is arranged into the spiral part, when the rubber shock pad body is connected with the spiral spring, the shock absorption stability can be increased, the shock absorption effect is enhanced, and abnormal sound is eliminated, so that the service life of the shock pad is prolonged; the anti-slip groove is formed in the base of the shock pad, so that the friction force of a contact surface is increased, the sliding is reduced, the movement abrasion is reduced, the abnormal sound is eliminated, the service life is prolonged, and the shock pad is safe and reliable.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in figures 1-3, the rubber shock pad of the present invention comprises a shock pad body 1 with an axial through hole 2 at the center, the cushion body 1 comprises a base 11 at the lower part and a spiral part 12 arranged at the upper part of the base 11, the base 11 and the spiral part 12 are integrally formed, a spiral groove matched with a spiral spring is arranged on the spiral part 12, the spiral spring is sleeved on the spiral part 12, a locking part 13 which is abutted against one end of the spiral spring is arranged at the joint of the spiral part 12 and the base 11, and through locking portion 13 realizes locking and spacing to coil spring, and during the use, coil spring overlaps and establishes on spiral portion 12, and coil spring's one end and 13 butts of locking portion, when avoiding coil spring to extend from top to bottom or compress, break away from spring shock pad body 1 to the reducible vibrations friction of spiral portion 12.

Further, the inner diameter of the through hole 2 at the upper part of the shock pad body 1 is smaller than the inner diameter of the through hole 2 at the lower part of the shock pad body 1. The inner diameter of the upper through hole is small, the inner diameter of the lower through hole is small, the swing arm shaft pin acts on the lower swing arm shaft pin of the vehicle body, clamping stagnation is not easy to occur, swing is flexible, and the shock absorption and buffering effects are favorably improved.

Further, the bottom wall of the shock pad body 1 is provided with anti-skid lines; in this embodiment, preferably, the bottom wall of the cushion body 1 is provided with a plurality of anti-slip grooves 3 uniformly distributed along the radial direction of the through hole 2; the inner end of the anti-skid groove 3 extends into the through hole 2 and is axially and uniformly distributed along the inner wall of the through hole 2. The anti-slip groove 3 increases the friction force of the contact surface, prevents sliding, reduces abnormal sound, reduces movement abrasion and prolongs the service life.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
