Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange that is easy to assemble and disassemble. Background Art

[0002] Flanges are used to connect pipes to each other and are the most commonly used connection parts on pipelines. Traditional flanges have bolt holes, and then bolts are used to fix the flanges. Flange connections are very convenient to use and can withstand greater pressure. Flange connections are widely used in industrial pipelines. However, during the installation or removal of ordinary flanges, bolts need to be installed or removed one by one, which is time-consuming and labor-intensive.

[0003] Publication No. CN 213809347 U discloses a flange that is easy to assemble and disassemble, comprising a first flange, a second flange, a connecting frame, a fixing claw, and bolts. The first flange is provided with equidistant limit posts and bolt holes, the limit posts and bolt holes being spaced apart. An edge of the first flange is provided with a mounting groove disposed outside the bolt hole. The second flange is provided with a plurality of limit holes. A fixing claw is movably provided at one end of the connecting frame, and the fixing claw is provided with a fixing hole. Bolts are sequentially passed through the fixing hole, the limit hole, and the bolt hole to securely connect the first and second flanges.

[0004] When in use, the existing device requires multiple fixing bolts for connection and locking, which makes it inconvenient for workers to disassemble and assemble, takes a long time, and it is inconvenient to locate multiple holes. Therefore, we propose a flange that is easy to disassemble and assemble. Summary of the Invention
