Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 6 The utility model provides the following technical solutions: an electric hot-melt connection device for socket connection of plastic pipes:

[0033] Embodiment 1: By setting the pressing plate 3, the tube body can be quickly fixed, which is convenient for melting operation. Figure 1 and Figure 3 As shown:

[0034] It comprises a bottom plate 1, a base is fixedly connected to the lower surface of the bottom plate 1, a limit plate 2 is fixedly connected to the upper surface of the bottom plate 1, a connecting rod 4 is slidably arranged inside the limit plate 2, and a pressing plate 3 is fixedly connected to the lower surface of the connecting rod 4;

[0035] An electric hot-melt connection device for socket connection of plastic pipes, further comprising:

[0036] A horizontal plate 5, the horizontal plate 5 is fixedly connected to the end of the connecting rod 4, a melting ring 8, a hinge 9 is arranged inside the melting ring 8, and the melting ring 8 is symmetrically distributed about the center of the hinge 9, and the lower melting ring 8 is fixedly connected to the bottom plate 1;

[0037] A fixed block 10 is fixedly connected to the surface of the upper melting ring 8, and a lap block 11 is fixedly connected to the surface of the lower melting ring 8, and a clamping block 14 is slidably arranged inside the lap block 11, the limit plate 2 is symmetrically distributed about the center of the bottom plate 1, and the limit plate 2 is a through structure, the left and right sides of the connecting rod 4 are fixedly connected with a protrusion 6, the upper surface of the protrusion 6 is fixedly connected with a first spring 7 which plays an elastic reset role, and the other side of the first spring 7 is fixedly connected to the inner wall of the limit plate 2.

[0038] During use, first pull the cross plate 5 and the connecting rod 4 to make the protrusion 6 squeeze the first spring 7, and then insert the tube to be processed into the limit plate 2. After loosening the connecting rod 4, the connecting rod 4 moves downward under the action of the protrusion 6 and the first spring 7, and then the pressure plate 3 supports the tube body, so that the tube body remains stable during processing. During the movement of the connecting rod 4, the protrusion 6 limits the moving distance of the connecting rod 4 to ensure stability.

[0039] Embodiment 2: Different from Embodiment 1, the upper melting ring 8 can be quickly engaged with the lower melting ring 8 by means of the provided clamping block 14 and the clamping slot 15, so as to facilitate the melting work. Figure 2 and Figure Figure 4 As shown:

[0041] After the tube body is docked inside the limit plate 2, the heads of adjacent tube bodies are fitted together. At this time, the upper melting ring 8 is rotated toward the lower melting ring 8. When the lower connecting rod 13 enters the deep groove 12, it will squeeze the block 14, so that the block 14 drives the slider 16 to squeeze the second spring 17. When the lower connecting rod 13 contacts the bottom of the deep groove 12, the block 14 and the groove 15 are in the same horizontal direction. Then, under the action of the slider 16 and the second spring 17, the block 14 enters the groove 15. At this time, the adjacent melting rings 8 are already engaged, and the melting work can start.

[0045] During the installation process, the second magnet 19 will be close to the first magnet 18. At this time, the repulsive magnetic force on the fixed block 10 will increase. When it is necessary to open the upper melting circle 8, the block 14 is pulled to move the end of the block 14 out of the slot 15. At this time, the fixed block 10 is rotated away from the lower melting circle 8 under the action of the repulsive magnetic force, and the upper melting circle 8 is away from the lower melting circle 8. The opening process is simple and safe, which protects the staff. During the movement of the block 14, the slider 16 limits the moving distance of the block 14 to ensure stability.
