Technical Field
[0001] This utility model relates to the field of electrothermal fusion sleeve technology, specifically to an electrothermal fusion sleeve insulation patch that is easy to install and replace. Background Technology
[0002] Electrofusion sleeve is a connecting pipe fitting that connects PE sheet to jacket pipe after it has been covered with wire mesh, bent and rolled, and then electrofused. It uses a special electrothermal wire mesh, and the melting effect at the joint is quite ideal. Its connection strength and sealing effect are very good.
[0003] Electrofusion sleeves have the advantages of high connection strength, good sealing effect, high air tightness, non-leakage of polyurethane, corrosion resistance, aging resistance, and convenient and quick construction. Under normal circumstances, they do not need to be replaced. However, during the installation process, when the electrofusion sleeve and the jacket tube have not yet melted and connected, the correspondence of their joint parts is not easy to handle, which leads to misalignment and displacement of the joint parts. Therefore, we propose an electrofusion sleeve insulation patch that is easy to install and replace. Utility Model Content

After the connection, the two clamps 46 will enter into the inside of the two clamping holes 53 under the action of the two first springs 45. In this case, the two fastening straps 32 can be fixed. After fixing, the two threaded rods 54 are rotated to adjust the position of the two sliders 52 according to the connection of the electrothermal sleeve 1, thereby adjusting the position of the two locking holes 53. In this way, the tightness of the two fastening bands 32 can be adjusted, so that the electrothermal sleeve 1 can be firmly fitted onto the pipe. This can prevent the electrothermal sleeve 1 from being misaligned or shifted during use. During the movement of the slider 52, the support ring 61 and the second spring 62 can support it, preventing the slider 52 from moving after the electrothermal sleeve 1 is fixed.
