The connecting ring and the anti-slip pads are movably connected in the connecting groove. The two groups of anti-slip pads are respectively located on the inner and outer sides of the connecting ring, and are both in contact with the connecting groove, thereby increasing the friction with the inner wall of the connecting groove, thereby improving the tightness of the connection.

[0016] 2. The utility model provides an assembled PVC pipe fitting. The connecting ring and the anti-skid pad are inserted into the connecting groove, and the buckle and the elastic sheet are driven to move at the same time. The outer side of the buckle enters the slot, and the elastic sheet enters the limiting slot, so that the connecting ring is fixed in the connecting groove, and the first PVC pipe and the second PVC pipe can be connected. When the two are disassembled, the push rod is pushed inward to drive the pressing rod to move inward, and the buckle is squeezed so that one side of it leaves the slot. Then the first PVC pipe and the second PVC pipe are pulled to both sides. When the elastic sheet moves outward, it is squeezed by the outer wall of the limiting slot, thereby causing deformation. Driven by the pulling force, it moves out of the limiting slot, and the two can be separated, thereby achieving the purpose of easy disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS
