[0002] The bushing is a matching part used outside mechanical parts to achieve the functions of sealing and wear protection. It refers to a ring sleeve that acts as a gasket. Automobile bushings generally include three parts: a metal outer shell, an intermediate rubber body and an inner tube. The three parts are connected together to form a complete bushing. Automobile drive shaft bushings are mainly sleeved on automobile drive shafts to play the role of connection and sealing.

[0003] The Chinese patent with publication number: CN211449400U discloses a sealing bushing for installation on automobile shafts, including a bushing body and a sealing ring. A through hole is provided in the middle of the bushing body to cooperate with the shaft, and a ring groove is opened at one end of the through hole. The inner side wall of the ring groove is an inner ring body, and the inner ring body has a plurality of groove bodies evenly distributed along the axial direction; the sealing ring is installed in the ring groove.

[0004] The above patents have the following problems:

[0005] The bushing body is fixed to the vehicle frame by a fixing part. When the bushing needs to be replaced after long-term use, in the above-mentioned article, the fixing part needs to be removed from the vehicle frame first, and then the new bushing needs to be installed on the vehicle frame again through the fixing part. This installation and disassembly method not only consumes a lot of time, but also is very inconvenient to disassemble and has poor practicality. In view of this, we propose an automobile shock-absorbing bushing. Utility Model Content

[0016] The beneficial effects of the utility model are:

[0017] 1. When disassembling the bushing body of the automobile shock-absorbing bushing, pull the pin outward. When the pin is disengaged from the limiting hole, the limiting of the adjusting block is released. When the limiting of the adjusting block is released, move the adjusting block downward. When the adjusting block is disengaged from the slot, the limiting of the sleeve column will be released. Rotate the sleeve column. When the position of the block on the sleeve column is rotated to be parallel to the first entry and exit grooves and the second entry and exit grooves, the sleeve column can be disassembled from the second set of holes and the first set of holes. At this time, the limiting of the first set of holes is released, and rotate the movable block. When the C-shaped bayonet is disengaged from the clamping column, the bushing body can be taken out from the fixing part, thereby realizing the disassembly of the bushing body. In this way, the bushing body can be taken out from the fixing part without disassembling the fixing part, which is convenient for replacing the bushing body and more practical.

The automobile shock-absorbing bushing, when installing the bushing body, the positioning block is sleeved with the positioning groove, so as to achieve the preliminary positioning and installation of the bushing body. When the first set of holes on the bushing body and the second set of holes on the fixing piece are parallel, the sleeve column is sleeved in the first set of holes and the second set of holes. When the sleeve column is sleeved in the first set of holes and the second set of holes, a plurality of clamping blocks will respectively enter the second annular groove and the first annular groove through the first entry and exit groove and the second entry and exit groove. At this time, the sleeve column is rotated. When the clamping block is misaligned with the first entry and exit groove and the second entry and exit groove, the bushing body will be limited in the fixing piece through the cooperation of a plurality of clamping blocks with the first entry and exit groove and the second entry and exit groove. In order to prevent the sleeve column from falling off and causing the bushing body to loosen, the adjusting block is sleeved in the slot, so as to achieve the limitation of the sleeve column. Then the pin is sleeved in the limiting hole. At this time, the limitation of the adjusting block is completed, thereby enhancing the stability of the sleeve column when limiting the position, and enhancing the fixity and stability of the bushing body when installing.
