In the prior art, for the connection of corrugated pipes, it is generally used to form a connecting section with a small outer diameter at one end, and then insert the connecting section into the other end of the adjacent corrugated pipe. Although such a structure is easy to install, However, when the pressure inside the pipeline is high, the connection is the weak point, and often disconnection occurs at the connection, so the use and maintenance of the entire pipeline should be applied

The invention relates to a corrugated pipe and a connecting structure. A first positioning ring and a second positioning ring are arranged at the two ends of the corrugated pipe respectively. The connecting structure comprises two buckling pieces capable of being buckled into a circular ring shape, wherein grooves are formed in the buckling pieces, the cross sections of the grooves are each in anisosceles trapezoid shape, the arc faces where the two sides of the isosceles trapezoid are located are used for abutting against a first positioning inclined face and a second positioning inclined face respectively, one end of one buckling piece and one end of the other buckling piece are hinged by a shaft, a detachable locking unit is arranged between the other end of one buckling piece and theother end of the other buckling piece. and the locking unit has a locking state and an unlocking state. According to the structure, the first positioning ring and the second positioning ring are arranged at the two ends of the corrugated pipe, then the first positioning ring and the second positioning ring are locked through the connecting structure, connection is reliable, breakage in use is avoided, meanwhile, the first positioning ring and the second positioning ring are in butt joint through a spherical surface, cooperation is reliable, and coaxiality errors are tolerable.
Description
technical field [0001] The invention relates to the technical field of bellows, in particular to a bellows and a connecting structure. Background technique [0002] When the pipe fittings are used, it is necessary to connect multiple pipe fittings, and the adjacent pipe fittings need to be connected through a connecting structure. The same is true for the bellows when they are used. In the prior art, for the connection of corrugated pipes, it is generally used to form a connecting section with a small outer diameter at one end, and then insert the connecting section into the other end of the adjacent corrugated pipe. Although such a structure is easy to install, However, when the pressure inside the pipeline is high, the connection is the weak point, and often disconnection occurs at the connection, so the use and maintenance of the entire pipeline should be applied. Contents of the invention [0003] The purpose of the present invention is to provide a corrugated pipe an...
