Among them, the main features of the pipe connector are: the front and rear parts are provided with flange pressure plates, and the inner cavity is provided with seals and clamping parts. Its main purpose is to connect two pipes horizontally and at fixed angles. The two sections of pipeline are fastened through the connector, and the rear end of the flange compression plate and the connecting body is fixed by axial bolts, so that it is very leak-proof, and the operation is convenient and fast, but there is one disadvantage that it is impossible to make an angle after fixing Transformation, such as the Chinese patent application number 2010201822871; another type of connector is a universal connector, which is more common in the market and is widely used in connecting rods with variable angles. For example, the universal connector is used to connect with the robot arm, which includes a connecting flange fixed at the fixed end, a universal joint assembled on the connecting tooling, and a positioner turntable set at one end of the universal joint. This type of connector realizes The variable-angle connection of rod parts has strong reliability and firm connection, such as the Chinese patent application number 2012200844317.
