Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a PE pipe hot-melt connection fixing device. Background Art

[0002] During the process of butt-joining PE pipes, it is usually necessary to place the ends of the two pipes on a bracket, then grind the ends of the two pipes with a milling cutter, then place an electric heating plate between the two pipes to heat their ends, and then remove the heating plate, so that the bracket drives the two groups of pipes to squeeze close to each other to complete the hot-melt butt-joining.

[0003] However, after hot-melt butt jointing, the interface needs to be cooled and solidified to complete a stable connection. The existing method usually uses natural cooling, which takes a long time to solidify after butt jointing. In addition, improper placement before complete solidification may cause bending. There is no fixing device to fix the interface to increase the butt joint effect, and the use efficiency is low. Therefore, we propose a PE pipe hot-melt connection fixing device to solve the above problems. Utility Model Content

At the same time, the metal plate can be in contact with the hot melt, so that the hot melt can be quickly cooled and solidified, thereby improving work efficiency.

[0014] Preferably, the inner walls of the first fixing ring and the second fixing ring are both provided with adsorption rubbers, the adsorption rubbers are located on both sides of the metal plate, and the ends of the adsorption rubbers are vacuum-set;

[0015] When the first fixing ring and the second fixing ring are used to fix the connection of the pipes, the adsorption rubber can be adsorbed on the outer walls of the two groups of pipes, thereby preventing the first fixing ring and the second fixing ring from shifting outside the pipes, making the first fixing ring and the second fixing ring more stable in fixing the pipes.

[0016] Preferably, a collecting groove is provided inside the second fixing ring, and the inner wall of the collecting groove is in contact with the outer wall of the metal plate;

[0017] The cooling liquid can be stored inside the collection tank, so that the low temperature is transferred to the top of the metal plate, so that the metal plate can better drive the cooling of the hot-melt joint of the two sets of pipes.

[0018] Preferably, a water inlet is provided at the top of the second fixing ring, and the bottom end of the water inlet extends to the inside of the collecting tank and is communicated with the collecting tank;

[0019] The coolant can be injected into the interior of the collecting tank through the water inlet, and the coolant can be replaced at the same time.
