Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber which is easy to install. Background Art

[0002] Shock absorbers are common accessories on vehicles. When a vehicle is driving, the tires will vibrate up and down due to the unevenness of the ground. Therefore, shock absorbers are installed to absorb the vibration caused by the wheels encountering uneven roads and improve riding comfort.

[0003] The oil seal installation structure of the shock absorber in the prior art is as follows: Figure 1 , 2 As shown in the figure, the gland, dustproof oil seal, oil seal pressure plate, main oil seal and guide are arranged on the piston rod in sequence. When installing, the parts are independent of each other, which makes assembly very troublesome and uncontrollable. Once the installation is not strict, the pressure plate is prone to oil leakage, which requires repeated oil replenishment. Moreover, after long-term use of the parts, the oil seal will become loose and may move up and down along the piston rod, greatly reducing the sealing performance. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a shock absorber that is easy to install, has a simpler structure, saves costs, is more convenient to install, the oil seal will not move up and down, and has a longer service life.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a shock absorber that is easy to install, comprising a tube body, a piston mechanism is installed in the tube body, a main seat is provided at one end of the tube body, and an end cover is provided at the other end of the tube body. One end of the piston rod of the piston mechanism passes through the end cover and is installed on the auxiliary seat, a guide is installed on the piston rod, a first oil seal mounting groove is provided on the end cover, a dustproof oil seal is embedded in the first oil seal mounting groove, a second oil seal mounting groove is provided on the guide, and the main oil seal is embedded in the second oil seal mounting groove.

[0006] In the above technical solution, the first stopper portions extending from the end cover are provided on the upper and lower sides of the dustproof oil seal.

[0007] In the above technical solution, second stoppers extending from the guide are provided on the upper and lower sides of the main oil seal.

[0008] In the above technical solution, a shock-absorbing spring is provided between the tube body and the auxiliary seat.

[0009] In the above technical solution, a piston rod hole is provided in the middle of the end cover, and the first oil seal mounting groove is an annular groove provided along the inner wall surface of the piston rod hole.

[0010] In the above technical solution, the second oil seal installation groove is an annular groove arranged along the inner wall surface of the guide.

[0011] To sum up, the technical solution of the utility model has the following beneficial effects compared with traditional technical means: the utility model optimizes the structure of the shock absorber, embeds the dustproof oil seal in the pressure cover, and embeds the main oil seal in the guide. On the one hand, the oil seal pressure plate is omitted, saving costs. On the other hand, the dustproof oil seal and the pressure cover, the main oil seal and the guide can be assembled in advance during installation and carried out in a distributed manner. The installation is more convenient, quick, and less prone to errors, and there will be no oil leakage. Moreover, the dustproof oil seal and the main oil seal are embedded in corresponding grooves, and will not move up and down during long-term use, so that the service life is greatly improved.
