[0027] First, push the two HDPE pipes into the placement ring 201 and the clamping ring 202, and then clamp them by applying pressure with the fastening block 203, and then put a heating plate between the end faces of the two HDPE pipes to heat and melt the end faces of the HDPE pipes, and then push one of the sliding bases 2 to make the two HDPE pipe end faces fit and contact, so that they can be hot-melt welded together, thereby completing the welding connection of the two HDPE pipes.
[0028] When the HDPE pipe is pushed into the placement ring 201 and the clamping ring 202 for clamping, the matching rings 3 at different positions will be pressed against according to the diameter of the HDPE pipe, so that the corresponding matching rings 3 will be displaced when the HDPE pipe is pushed in. Before pushing the corresponding matching ring 3, the limiting rod 204 is rotated to move to the matching ring 3 at the corresponding position, so that the remaining matching rings 3 will not be displaced together, so that the matching ring 3 can match the diameter of the HDPE pipe, and then it is tightened by the fastening block 203, so that it can adapt to HDPE pipes of different diameters.
[0029] Furthermore, the movable component includes a connecting groove 302, a sliding groove 3021, a lifting groove 303, a connecting block 304, a sliding rod 3041 and a deflection groove 306, the connecting groove 302 is arranged at the bottom of the matching ring 3, the sliding groove 3021 is arranged on both sides of the middle of the connecting groove 302, the lifting groove 303 is arranged on one side of the connecting groove 302, the deflection groove 306 is arranged on the top of one side of the matching ring 3, the connecting block 304 is connected to the deflection groove 306, the sliding rod 3041 is arranged at both ends of the connecting block 304, and the connecting block 304 It is a block hinged in the deflection groove 306 by sliding rods 3041 on both sides of one end, and the two sides of the end of the connecting block 304 away from the deflection groove 306 are connected with the sliding groove 3021 through the sliding rods 3041. Several combinations of semicircular rings of the matching ring 3 are connected and spliced together through the connecting block 304. The lifting groove 303 is an opening on the side of the matching ring 3 away from the deflection groove 306, and the lifting groove 303 is matched with the sliding rods 3041 on both sides of one end of the connecting block 304, and one side of the lifting groove 303 is connected with the connecting groove 302.
[0030] At the same time, when the matching ring 3 at the corresponding position is displaced, it is moved by the connecting block 304 in the top deflection groove 306 cooperating with the connecting groove 302. When moving to one end of the connecting groove 302, the connecting block 304 will deflect in the deflection groove 306, thereby driving the displaced matching ring 3 to move upward. At the same time, the end of the connecting block 304 connected to the connecting groove 302 will be displaced along the lifting groove 303, so that the pushed matching ring 3 will finally be completely displaced to the side of the matching ring 3 without displacement, so that the HDPE pipe can be smoothly embedded and clamped.
[0031] The following is a specific implementation process of the present invention. First, two HDPE tubes are pushed into the placement ring 201 and the clamping ring 202, and then clamped by applying pressure from the fastening block 203. A heating plate is then placed between the end faces of the two HDPE tubes to heat and melt the end faces of the HDPE tubes. Then, one of the sliding bases 2 is pushed to allow the two HDPE tube end faces to fit and contact each other so that they can be hot-melt welded together, thereby completing the welding connection of the two HDPE tubes. When the HDPE tube is pushed into the placement ring 201 and the clamping ring 202 for clamping, it will abut against the matching ring 3 at different positions according to the diameter of the HDPE tube, so that the corresponding matching ring 3 will drive the corresponding matching ring 3 to move when the HDPE tube is pushed in. Before pushing the corresponding matching ring 3, the limiting rod 204 is rotated. To move to the matching ring 3 at the corresponding position, so that the remaining matching rings 3 will not be driven to move together, so that the matching ring 3 can match the diameter of the HDPE pipe, and then be fastened by the fastening block 203, so that it can adapt to HDPE pipes of different diameters. At the same time, when the matching ring 3 at the corresponding position is displaced, it is moved by the connecting block 304 in the top deflection groove 306 to cooperate with the connecting groove 302. When moving to one end of the connecting groove 302, the connecting block 304 will deflect in the deflection groove 306, thereby driving the displaced matching ring 3 to move upward. At the same time, the end of the connecting block 304 connected to the connecting groove 302 will be displaced along the lifting groove 303, so that the pushed matching ring 3 will finally be completely displaced to the side of the matching ring 3 without displacement, so that the HDPE pipe can be smoothly embedded and clamped.
