Technical Field
[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a quick-release interface for plate heat exchangers. Background Art
[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The interface of the plate heat exchanger is used for water inlet and outlet, but the existing quick-release interface of the plate heat exchanger has some shortcomings when used;
[0003] The existing quick-release interface for plate heat exchangers adopts threaded connection, so that when the quick-release interface for plate heat exchangers is connected to the connecting pipe, more bolts are needed to align and connect and fix, so as to ensure that the quick-release interface for plate heat exchangers and the connecting pipe can be fully fitted, thereby avoiding gaps between the quick-release interface for plate heat exchangers and the connecting pipe, thereby avoiding water outflow. However, this results in the need to twist the bolts multiple times when disassembling and assembling the quick-release interface for plate heat exchangers and the connecting pipe, which requires a long time, and after long-term use, the bolts will rust, further increasing the difficulty of threaded connection. Utility Model Content

[0012] Furthermore, one end of the moving block close to the conical structure of the second connection port is configured as a slope structure, and the configuration of the slope structure can better ensure that the moving block is directly engaged with the first connection port when moving.
[0013] Furthermore, a ball is movably provided on the front surface of the automatic telescopic rod, and the ball is utilized to facilitate the sliding movement of the automatic telescopic rod.
[0014] Furthermore, a group of L-shaped slide grooves are arranged on the inner wall of the circular groove on the side of the first connecting port, and the L-shaped slide grooves are adapted to the moving block and the automatic telescopic rod to ensure that the moving block and the automatic telescopic rod can slide in the L-shaped slide grooves on the side of the first connecting port.
[0015] Furthermore, a second circular groove is fixedly provided at one end of the L-shaped slide groove in the circular groove on the side of the first connecting port, and an inclined surface is provided between the second circular groove and the L-shaped slide groove inside the first connecting port. The second circular groove inside the first connecting port is adapted to the automatic telescopic rod, ensuring that the automatic telescopic rod can directly move into the second circular groove through the inclined surface when moving, thereby being clamped with the second circular groove.
[0016] Beneficial effects of the utility model:
[0017] The utility model can realize the clamping fixation of the first connection port and the second connection port by plugging and rotating the moving block and the automatic telescopic rod, and then only needs to rotate two sets of bolts to realize double fixation, so as to realize the stable connection between the first connection port and the second connection port, so that there is no need to use more bolts to connect the first connection port and the second connection port, so that the first connection port and the second connection port are more convenient to disassemble and assemble, the operation is quick, and the utility model has strong practicality.
