Pipe connecting structure

Abstract

The invention discloses a pipe connecting structure which comprises a connector provided with a fluid channel, round pipes in butting connection with the fluid channel, and clamping sleeves arranged at the two ends of the connector. The inner end faces the two ends of the connector are each a conical face, and the outer end faces of the two ends of the connector are each provided with an external thread. Each clamping sleeve is formed by welding a lock nut and a clamping device, and a gap is reserved between each lock nut and the corresponding clamping device and used for containing the port of the connector in a sleeving mode. The size of each lock nut is matched with the diameter of the outer end face of the connector, and the middle of each clamping device is provided with an internal thread engaged with the external thread on the outer end face of the connector. The clamping devices are arranged between the lock nuts and the connector, and pipe inserting through holes matched with the round pipes in diameter are formed in the middles of the clamping devices. The ends, facing the connector, of the clamping devices are also conical faces. The axial included angle of the conical face of the connector is larger than that of the conical face of each clamping device. By means of the pipe connecting structure, rapid pipe connection can be achieved.

Description

technical field [0001] The invention relates to the field of pipeline engineering, in particular to a connecting pipe structure. Background technique [0002] In the existing construction site, traditional methods are often used for water supply or other fluid pipelines, such as arranging steel wires outside the pipelines for binding and winding, or using flanges for butt welding to weld the two pipelines to death, but this operation method not only It is time-consuming and labor-intensive, and a lot of labor costs are wasted. Moreover, when the engineering process is fast, the pipeline needs to be relocated. At this time, it takes a lot of time to disassemble and reassemble the pipeline. The disassembly of the flange welding form is more troublesome, and even the cost of purchasing a new flange needs to be increased. Contents of the invention [0003] The present invention aims to provide a connection structure to solve the above problems. [0004] To achieve the above ...
