Description

High-pressure pipe connecting assembly for manually installing spraying machine Technical Field The invention relates to the technical field of connection of matched pipe fittings of a spraying machine, in particular to a high-pressure pipe connection assembly capable of being manually installed for the spraying machine. Background The high-pressure conveying pipeline of the spraying machine is reliably connected with the spraying machine host and the spray gun, and the sealing performance, the operation safety and the site construction efficiency of spraying operation are directly determined. If the high-pressure pipeline joint is unstable in connection and poor in sealing, the problems of leakage, looseness and the like are easy to occur, the construction quality is affected, potential safety hazards exist, and the overall operation efficiency is reduced. The traditional high-pressure pipe is connected with the high-pressure gun and the spraying machine by using two wrenches at two ends of an old structure, because the wrenches for contact of the internal taper and the external taper of two metal parts are tightly twisted, if the torque force is insufficient, the leakage is likely to occur, and the joint on the gun body is a 360-degree rotary joint, and the loosening condition exists, at least two tool wrenches are used for operation, and the operation is troublesome due to the fact that accessories and cost are increased. Disclosure of Invention The invention aims to provide a high-pressure pipe connecting assembly for a spraying machine, which can be manually installed and solves the problems that the traditional spraying machine is complicated to assemble and disassemble, the cost of accessories and tools is high and the construction efficiency is low due to the fact that tools such as a spanner are needed to be used for connecting the high-pressure pipe. In order to solve the technical problems, the invention is realized by the following technical scheme: The invention relates to a high-pressure pipe connecting assembly for a spraying machine, which comprises a high-pressure pipe body, two connecting assemblies, a high-pressure gun and a spraying machine body, wherein the two connecting assemblies are sleeved at two ends of the high-pressure pipe body, the connecting assemblies comprise tightening knobs, the outer surfaces of the tightening knobs are fixedly connected with uniformly distributed adjusting teeth, two sealing grooves are formed in the outer surfaces of the high-pressure pipe body, sealing pieces are inlaid in the two sealing grooves, internal threads are formed in the inner walls of the two tightening knobs, a first external thread matched with the internal threads is arranged at the connecting end of the high-pressure gun, and a second external thread matched with the internal threads is arranged at the output end of the spraying machine body. Further, the connecting end of the high-pressure gun is detachably and hermetically connected with one end of the high-pressure pipe body through a connecting assembly. Further, the output end of the spraying machine body is detachably and hermetically connected with the other end of the high-pressure pipe body through a connecting component. Further, the sealing element is an O-shaped sealing ring. Further, the sealing element is made of wear-resistant rubber. Further, the connecting end of the high-pressure pipe body is provided with a limiting step.
