[0002] As we all know, the low-pressure oil return pipe is an important part of the car, responsible for the transmission of oil, water, gas and hydraulic force. Although the structures of automobile hoses for different purposes are different, they are generally divided into three basic parts: inner layer, reinforcement layer and outer layer. The existing low-pressure oil return pipe is generally installed at the bottom of the car. In order to prevent stones from splashing onto the oil return pipe when the car is driving, a protective frame will be set on the low-pressure oil return pipe to prevent stones from causing damage to the oil return pipe.

[0003] However, the protective frame on the existing low-pressure oil return pipe assembly is generally fixed on the low-pressure oil return pipe assembly. When the protective frame is used for a long time and is damaged and needs to be replaced, it is inconvenient to disassemble and replace it with a new protective frame. Utility Model Content
