Problems solved by technology

[0002] In the field of industrial automation, pneumatic or hydraulic pressure is usually used as the power of automation. To complete the connection of liquid or gas delivery pipelines is an indispensable part in the field of automation. Pipelines of different lengths and different extension directions need to be connected. The pipe connection is usually achieved through pipe joints. The existing pipe joint structure is usually that the joints on both sides are connected through connectors, and the two ends are respectively connected to external pipes. When the joints on both sides are connected through connectors, due to the Rotation, the joints on both sides will produce a certain rotational movement, especially when the joints on both sides have position requirements, which affects the stability of the joint connection on both sides, and it is easy to cause liquid or gas leakage in the joints

Abstract

The invention provides a positioning structure of pipe connectors. The positioning structure of the pipe connectors is simple, avoids the rotation displacement of the connectors on the two sides, guarantees the connection stability of the connectors on the two sides, and effectively avoids the phenomenon of air leakage or liquid leakage in the joint of the pipe connectors. The positioning structure comprises the first connector and the second connector which are connected through a fastening nut. The positioning structure is characterized in that a plurality of positioning pins are arranged on the end surface of the first connector, and the end surface, connected with the first connector, of the second connector is provided with positioning holes matched with the positioning pins.
