AI Technical Summary
Technical Problem
The existing oil pressure shock absorbers cannot effectively prevent dust from entering the inside of the oil cylinder during operation, and it is difficult to effectively dissipate heat, resulting in a shortened service life.
Method used
A hydraulic shock absorber with dust-proof function was designed. The dust-proof mechanism was used to prevent dust from entering through sealed connections and telescopic tubes. At the same time, the heat dissipation mechanism was used to quickly dissipate heat through heat dissipation fins, heat conduction rods and thermal oil.
Benefits of technology
It realizes effective dust prevention and heat dissipation of the oil pressure shock absorber during operation, extending the service life of the equipment.

Abstract
The utility model discloses an oil damper with a dustproof function, and relates to the technical field of oil dampers, the oil damper comprises a cylinder body, a dustproof mechanism is arranged at the upper end of the cylinder body, a heat dissipation mechanism is arranged on the outer surface of the cylinder body, the dustproof mechanism comprises a first dustproof cover, a piston rod is fixedly arranged at the lower end of the first dustproof cover, and a piston rod is arranged at the lower end of the piston rod. A second dustproof cover is fixedly arranged at the upper end of the cylinder body, sealing rubber rings are arranged at the upper end of the second dustproof cover and the lower end of the first dustproof cover correspondingly, connecting flanges are arranged at one ends of the opposite faces of the two sealing rubber rings correspondingly, and a telescopic pipe is fixedly arranged at one ends of the opposite faces of the two connecting flanges jointly. According to the oil pressure shock absorber, the dustproof mechanism is connected in a sealed mode to achieve the dustproof effect, the oil pressure shock absorber can effectively prevent dust from entering an oil cylinder, heat generated by the oil pressure shock absorber can be rapidly conducted and dissipated through the heat dissipation mechanism, and therefore the oil pressure shock absorber can effectively dissipate heat of the oil cylinder.
