Description

During the manufacturing and use of lasers, multi-station finished product testing of the laser cooling system is often required. Furthermore, all testing and use must be conducted in a water-cooled environment.

At present, the cooling systems of many high-power laser equipment require large water flow, so joints with relatively large diameter pagoda structures are used at the water inlet and outlet. Since the pagoda structure in the prior art is inconvenient for plugging and unplugging, operators will first cut off the head of the water pipe during installation, and then insert the joint into the water pipe. In addition, in order to prevent excessive water pressure from causing the opening of the water pipe head to be torn by the strong impact of the water flow, a clamp will be installed at the rear end where the water pipe and the joint abut, so that the water pipe and the joint are tightly connected. There will be no loosening or falling off during the process.
