Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a splicable corrugated pipe. Background Technique

[0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange pipes, diaphragm capsules and metal hoses, etc. Metal corrugated pipes are mainly used for compensating pipeline thermal deformation, shock absorption, absorbing pipeline settlement deformation, etc., and are widely used in petrochemical, instrumentation, aerospace, chemical industry, electric power, cement, metallurgy and other industries. Corrugated pipes made of other materials such as plastics play an irreplaceable role in fields such as medium transportation, power wire threading, machine tools, and household appliances.

[0003] For example, the Chinese utility model provides "a splicable corrugated pipe", publication number: CN214367079U. This application includes a corrugated pipe main body. An enhancing mechanism is arranged on the outer part of the corrugated pipe main body. A splicing mechanism is arranged on the lower outer surface of the corrugated pipe main body. Wave-shaped patterns are arranged on the outer wall of the enhancing mechanism. For the splicable corrugated pipe of the utility model, by arranging the enhancing mechanism, the service life of the corrugated pipe can be effectively improved, and the strength of the corrugated pipe can be effectively improved. The main material of the wear-resistant layer is wear-resistant rubber, which has good wear resistance and can improve the wear resistance of the corrugated pipe and the service life of the corrugated pipe. The main material of the anti-corrosion layer is polyurethane, which has good anti-corrosion performance. The main material of the reinforcing layer is carbon black, which can enhance the strength of the corrugated pipe and ensure the good use of the corrugated pipe. By arranging the splicing mechanism, it is more convenient for people to splice the corrugated pipe, which is convenient for later disassembly and maintenance, and brings a better application prospect.

[0004] In the above technology, the splicable corrugated pipe uses splicing mechanisms such as connecting pipes, first snap rings, second snap rings, first limit pins, second limit pins, first threaded pipes and second threaded pipes to quickly splice the corrugated pipe during use. However, due to the lack of a good sealing structure between the corrugated pipe and the splicing mechanism during the splicing process, the fluid inside the corrugated pipe is likely to leak along the surface of the splicing mechanism during long-term use, thus affecting the safety of internal fluid transportation and not meeting the usage requirements of personnel.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, as shown in the present utility model Figures 1-5 shown, guide cross bars 19 are fixedly connected to the peripheries of the right ends of the cavities 12. The surface of the moving guide rod 11 is movably connected to the right ends of the guide cross bars 19.

[0029] In this technical solution, through the setting of the guide cross bars 19, the purpose of guiding the moving guide rod 11 is achieved, avoiding the bending of the moving guide rod 11 due to force.
