Description

Technical Field

[0001] The utility model relates to the technical field of tricycle shock absorbers, in particular to a rust-proof tricycle shock absorber. Background Art

[0002] Three-wheeled vehicles have good stability and flexible steering, making them very suitable for short-distance travel, especially for the elderly and disabled. With the arrival of an aging population in my country, the market prospects are very broad. Therefore, based on the above two points, battery tricycles have become one of the best means of transportation that is particularly suitable for the elderly and disabled. The shock absorber of the tricycle can eliminate the bumpy feeling of the road when the tricycle is driving, and improve the riding comfort.

[0003] In the prior art, the authorized patent with the announcement number CN220416067U discloses a tricycle shock absorber, including a cavity tube, an inner tube installed in the cavity tube, a first clamping ring integrally provided on the inner side of the cavity tube, a first internally threaded tube connected to the bottom of the cavity tube, a second clamping ring integrally provided on the outer side of the body of the inner tube located inside the cavity tube, a second internally threaded tube connected to the top of the inner tube, the second clamping ring located below the first clamping ring, a spring installed in the inner cavity of the connector between the cavity tube and the inner tube, both ends of the spring are sleeved on the first internally threaded tube and the second internally threaded tube, and a connector is threadedly installed at the position of the first internally threaded tube and the second internally threaded tube. In the utility model, while maintaining the telescopic shock absorbing function of the shock absorber, a universal spring can be used, thereby facilitating the production and assembly of the shock absorber, and at the same time, the connector is fixed by threaded connection, which is convenient for assembly, and the spring is not easily damaged by external forces. The assembled connector is both a connector and an end seal.

[0004] However, the above technical solution still has the following shortcomings when in use: the spring of the above device is installed in the inner cavity of the cavity tube. When the elastic force of the spring is damaged and needs to be replaced, the overall assembly of the device and the replacement of the spring are inconvenient. In this regard, we propose a rust-proof tricycle shock absorber to solve the above-mentioned problems. Utility Model Content

[0011] Preferably, the outer walls of the cavity tube and the inner tube are sprayed with an anti-rust coating.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model sets the bottom end of the cavity tube as an opening and installs a sealing cover plate at the opening of the bottom end of the cavity tube, so that after removing the sealing cover plate, the spring and the inner tube can be taken out, which is convenient for the assembly of the whole device and the replacement of the spring. The sealing cover plate is fixedly installed on the cavity tube through the cooperation of the set mounting seat, the fastening bolt and the threaded seat, and the connection between the sealing cover plate and the cavity tube is strengthened by the threaded connection of the set threaded sleeve and the cavity tube, so that the connection between the sealing cover plate and the cavity tube is more firm and stable.
