Description

Tear-resistant shock-absorbing bushing Technical Field The utility model relates to the field of bushing processing, in particular to a tearing-resistant damping bushing. Background The bushing is used outside mechanical parts to achieve the effects of sealing, wear protection and the like, and is used as a bushing, and in the field of valve application, a corrosion-resistant material such as polytetrafluoroethylene or graphite is generally used for sealing in a valve cover. Along with the frequent use of various mechanical devices and vehicles, the complex working conditions such as stress, impact force and the like borne by the mechanical devices are continuously increased. The structure and the material of the conventional common damping bushing are difficult to effectively resist the external force action with high strength, and the outer sleeve part made of rubber is extremely easy to tear. Once tearing occurs, the shock absorption function of the lining is greatly reduced, and abnormal abrasion, looseness and other conditions of the whole equipment or relevant parts of the vehicle can be caused, so that the normal operation of the equipment is affected, and even potential risks are brought to the safety of a user. The device has the following defects that the cost is greatly increased due to the improvement measure of the prior lining, so that the product is limited in market popularization, or a certain damping effect is sacrificed while the tear resistance is improved, the actual requirement cannot be well met, and the tear-resistant damping lining is provided for solving the problem. Disclosure of utility model In order to make up for the defects, the utility model provides a tearing-resistant shock-absorbing bushing, which aims to solve the problems of insufficient tearing resistance and insufficient shock resistance of the bushing in the prior art. In order to achieve the purpose, the anti-tearing shock-absorbing bushing comprises a bushing body, wherein the bottom end of the outer wall of the bushing body is fixedly connected with a bushing seat, the upper surface of the bushing seat is provided with a fixing groove, a plurality of groups of gaskets which are uniformly distributed are fixedly arranged in the inner wall of the bushing body, the upper surface of the bushing seat is provided with an anti-tearing assembly, the upper surface of the bushing body is provided with an auxiliary assembly, the anti-tearing assembly comprises a supporting ring, the upper surface of the supporting ring is fixedly connected with a plurality of groups of positioning plates which are uniformly distributed, the outer wall of the positioning plate is fixedly provided with rubber strips, and the rear surface of the positioning plate is provided with a limiting groove.
