The high-pressure oil pipe is used as an oil pipe between two hydraulic elements in a hydraulic system and structurally comprises a rubber pipe in the middle and joints connected to two ends of the rubber pipe. The fitting at each end typically includes a hollow core tube structure with one end of the core tube connected to the hose and the other end mounted to the hydraulic component with a nut. In practical use, the core tube and the rubber tube are connected into a high-pressure oil pipe and then are mounted on the hydraulic element by using the nut, and at the end of screwing the nut and the hydraulic element, the core tube and the rubber tube rotate along with screwing due to the increase of friction force, so that the mounting quality is influenced, and the mounting efficiency is reduced.
In order to avoid the above situation, the first way to do this is to process the hexagon on the outer circumference of the core tube in advance, so that when the nut is tightened, the hexagon is clamped by a tool, so that the core tube can be kept still all the time, and the joint is conveniently and quickly installed. However, the hexagonal body usually protrudes out of the core tube obviously, and when the core tube is manufactured and selected, the tube with larger outer diameter is selected mainly according to the size of the external circle of the hexagonal body, so that the part outside the hexagonal body needs to be turned to remove more waste materials, and the utilization rate of raw materials is lower, so that the method is gradually abandoned.

The method does not need to consider the influence of the protrusion of the hexagon, and the core pipe can be processed by selecting the pipe with smaller outer diameter, so that the turning amount of waste materials can be reduced, and the utilization rate of raw materials is improved.
However, in this way, the hexagon is fixed and assembled on the core tube by interference fit or screw thread. The installation of interference fit must adopt the pressure equipment machine just can accomplish, and the use of pressure equipment machine can increase the assembly cost that connects, and just goes on after having set to the core pipe for the nut during pressure equipment, and the piece is more troublesome to get on the pressure equipment machine to connect, and whole packaging efficiency is not very high. Thread mounting means need process the external screw thread on the core pipe outer peripheral face, processes the internal thread on the hexagon, and the machining cost is higher, and thread mounting itself is rotatory installation, and it can only one-way play, can clamp the hexagon when the installation promptly, guarantees that the nut screws up smoothly, nevertheless if need pull down when connecting temporarily, the unable effect of clamping that realizes of this hexagon, the nut still can drive core pipe and rubber tube and take place certain rotation, uses to experience not fine.
