[0020] A positioning half ring 2 and a docking half ring 3 are fixed around the outer tube surface of the air conditioner condenser tube body 1. The positioning half ring 2 is distributed at the front side of the docking half ring 3. A connecting block 22 is welded to the middle of the outer ring surface of the positioning half ring 2. A plug-in groove 23 is opened inside the left end of the connecting block 22. A fixing block 31 is welded to the middle of the outer ring surface of the docking half ring 3. A docking plate 32 is movably connected to the inner side of the fixing block 31 through a hinge column 33. The side end of the docking plate 32 is connected to a rectangular plug plate 4 through an adjusting stud 41. The rectangular plug plate 4 is plugged into the corresponding plug-in groove 23 on the inner side of the connecting block 22.

[0021] When the condenser tube of the condenser in the bus air-conditioning unit is disassembled for maintenance, the adjusting screw 41 on the outside of the joint between the two air-conditioning condenser tube bodies 1 is rotated to move the rectangular plug plate 4 out of the plug-in groove 23 on the inner side of the connecting block 22, and the joint of the two air-conditioning condenser tube bodies 1 can be disassembled by rotating the docking plate 32 outward. One of the air-conditioning condenser tube bodies 1 can be removed for maintenance or replacement and then installed back into the condenser, so that the bus air-conditioning unit can operate and cool normally.
