Problems solved by technology
[0002] In the process of production and processing, two pipes are often connected by welding, but if some pipes are damaged, it is difficult to replace the damaged pipes, which brings inconvenience to production; in order to facilitate subsequent maintenance, often during production and processing Install flanges and other fasteners at the joints of the pipes, and then use the flanges to connect the two pipes. Although it is convenient for installation and maintenance, in order to install the flanges on the pipes, it is necessary to install the flanges on the outside of the pipes. Tapping and other operations, the whole process is time-consuming and labor-intensive, especially for pipes with larger diameters

Embodiment Construction
[0014] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. .
[0015] Such as figure 1 As shown, the specific structure of the present invention is as follows: it includes a concentrically arranged connecting piece and a locking ring 1, the connecting piece includes an insert ring 2 and an outer ring 3, and the two ends of the insert ring 2 are inserted into the pipes 17 on both sides during installation. Inside, locking bolts 4 are arranged in an array on the side wall of the insertion ring 2, and one end of the locking bolt 4 passes through the side wall of the insertion ring 2 and abuts against the inner wall of the pipe 17 to temporarily fix the pipe 17. The i...
