[0002] A fracturing truck is a special vehicle used to inject high-pressure, large-volume fracturing fluid into a well, pressurize the formation and squeeze the proppant into the crack. It is mainly used for various fracturing operations in oil, gas and water wells, and can also be used for hydraulic sandblasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal on ships. When the output port of the fracturing truck injects a large-volume fracturing fluid into the ground, due to the high pressure of the fracturing fluid, the sealing degree of the connection between the output port and the external docking pipe is required to be high. In the prior art, the connection between the output port of the fracturing truck and the pipeline mostly adopts a screw-on docking sleeve, and the interface position is tightened and fixed by rotating the docking sleeve. However, the fixation between the output port and the pipeline is not reliable. Under the impact of the head pressure, the pipeline will still shake, thereby affecting the sealing stability of the connection position. In view of this, in-depth research on the above-mentioned problems has led to the creation of this case. Utility Model Content
