Description

Technical Field

[0001] The utility model relates to the technical field of rubber parts, in particular to a rubber part with a shock-absorbing function. Background Art

[0002] The characteristics of rubber are that it has both high elasticity and high viscosity. The elasticity of rubber is generated by the change of its curled molecular conformation. The interaction between rubber molecules will hinder the movement of the molecular chain, and it also shows viscosity, so that stress and strain are often in an unbalanced state. The curled long-chain molecular structure of rubber and the weak secondary force between molecules make the rubber material present unique viscoelastic properties, so it has good shock absorption, sound insulation and buffering properties. Rubber parts are widely used to isolate vibration and absorb shock because they have the characteristics of hysteresis, damping and reversible large deformation. As an important type of shock absorbing component, rubber shock absorbers have been widely used in various types of machinery, automobiles, railway locomotives, water transportation vehicles, aircraft and other aircraft.

[0003] According to Chinese patent CN217814759U, an impact-resistant, oil-proof and shock-absorbing composite rubber part for an air conditioner is provided. First, a rubber bottom block is threaded onto a first rubber part through a threaded rubber part, a damping oil tank is placed in a second rubber part, a baffle is placed under a steel ring, the steel ring is inserted between the first rubber part and the second rubber part, the steel ring is screwed to the bottom end of the compressor, and then the compressor is pressed down. The third rubber part, the fourth rubber part and the rubber bottom block can act as suction cups to fix the device, and the third rubber part, the fourth rubber part and the rubber bottom block are equivalent to three groups of suction cups, which can have a stronger adsorption effect and can prevent one group from losing the adsorption effect, resulting in a loss of adsorption effect.

[0004] In the above device, the rubber part only relies on the suction cup and the spring to reduce shock during shock absorption, and the effect is not good. Since there is no damping limit component inside the spring, the rubber ring connected to the spring will keep shaking up and down when subjected to vibration impact, and the fatigue strength of the spring force will increase, which in turn affects the service life of the rubber part. Therefore, a rubber part with shock absorption function is proposed to solve the above problem. Utility Model Content
