[0002] A hydraulic oil pipe is a pipe used to transmit hydraulic oil. Its main function is to transmit the oil pressure extracted from the hydraulic system to the hydraulic actuator to perform the corresponding control function. The hydraulic oil pipe usually needs to be clean, leak-free, bubble-free, and maintain sufficient strength and toughness to ensure the normal operation of the hydraulic system. It is one of the most important components in the hydraulic system and is mainly used to transmit hydraulic oil and transfer energy from the hydraulic source to hydraulic actuators, such as hydraulic cylinders and hydraulic motors.

[0003] The components of hydraulic oil pipes mainly include pipe bodies, joints, etc. These components work together to ensure that the hydraulic oil pipes can stably and efficiently transmit hydraulic oil to meet the needs of various hydraulic systems. When multiple hydraulic oil pipes are connected, joints are required at the hydraulic oil ports to ensure the stability and reliability of the hydraulic system, adapt to different working environments and needs, and improve the overall performance of the system.

[0004] Currently, when connecting two hydraulic oil pipes, you first need to select an oil pipe that meets the system requirements, then test it to ensure that the oil pipe is in good condition, then select a suitable joint, install the oil pipe on the joint, and use tools to tighten and fix it, then the pipe connection can be completed.

[0005] However, when connecting the oil pipes, since the adjacent ends of the two oil pipes are connected to the ends corresponding to the respective joints, tools are needed to be used for compression and fixation, which makes the operation of connecting the oil pipes more troublesome and easily reduces work efficiency.

[0015] The utility model is further configured such that the first bellows moves in the first interface, and the second bellows moves in the second interface.

[0016] By adopting the above technical solution, the first bellows can be deformed in the first interface and the second bellows can be deformed in the second interface, so that the first interface and the second interface respectively protect the corresponding first bellows and the second bellows.

[0017] The utility model is further configured such that both the first oil pipe and the second oil pipe are made of a combination of carbon fiber composite material and high-performance oil-resistant rubber.

[0029] A hydraulic oil pipe, such as Figure 1-3As shown, it includes a first oil pipe 1 and a second oil pipe 6, and corresponding first interfaces 2 and second interfaces 7 are respectively arranged on adjacent sides of the first oil pipe 1 and the second oil pipe 6.

[0030] Then, a first bellows 3 is arranged on the top of the first oil pipe 1, and a first magnetic ring 4 is installed on the outer surface of the first bellows 3. The first bellows 3 can be extended and contracted by the movement of the first magnetic ring 4, and the first magnetic ring 4 and the first interface 2 are connected by a first spring 5.
