Flange convenient to mount and dismount

Abstract

The invention discloses a flange convenient to mount and dismount. The flange comprises a positive flange plate and a negative flange plate; teeth are uniformly arranged on the outer wall of a guide rod; a negative flange neck is arranged on the outer wall of the left side of the negative flange plate; the other end of a spring is connected with a vertical plate; opposite inner ends of two sets ofgears are engaged with the teeth on the outer wall of the guide rod; a clamping base is fixedly mounted on the outer wall of a positive flange neck; and a dowel pin is inserted on the outer wall of the clamping base. The device is simply operated and conveniently assembled and disassembled; through pressing of a fixed rod, the gears drive the guide rod to move to the right side, so that the rightend of the positive flange neck is conveniently bonded with the left end of the negative flange neck to finish the mounting process; during disassembling, the dowel pin is pulled out to relieve locking of the fixed rod; the spring is returned to drive a vertical plate to move to the left side; and the vertical plate pushes the guide rod to move to the left side to realize separation of the positive flange neck from the negative flange neck, so that the disassembly efficiency is effectively improved, and the disassembly inconvenience caused by bolt rusting is prevented.

Description

technical field [0001] The invention relates to the technical field of flanges, in particular to a flange that is easy to assemble and disassemble. Background technique [0002] In the prior art, flanges are often used for large-scale projects such as pipeline connections. However, when using existing flanges, two connected flanges need to be installed through bolts. It takes a certain amount of time to disassemble and install through bolts. At the same time, the bolts are prone to rust and corrosion during long-term use, which is not convenient for the staff to disassemble later, and affects the work efficiency of the staff. Therefore, we propose a flange that is easy to assemble and disassemble. Contents of the invention [0003] The purpose of the present invention is to provide a flange that is easy to assemble and disassemble, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present in...
