DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0022] See also Figure 1-3 The utility model embodiment provides a technical solution: a new type of thermal insulation pipe connector, including a connecting sleeve 1 and a connecting insert 2, the two ends of the connecting sleeve 1 are respectively provided with connecting grooves 3, the interior of the connecting sleeve 1 is provided with a connecting platform 4, the end surface of the connecting platform 4 is provided with an embedding groove 5, the interior of the embedding groove 5 is provided with a sealing gasket 6, the connecting insert 2 includes a fixing ring 7, a tightening ring 8 and a locking bolt 9, the edge of the fixing ring 7 is provided with a snap groove 10, the edge of the tightening ring 8 is provided with a raised snap ring 11, the snap ring 11 is embedded in the snap groove 10 and is detachably connected to the fixing ring 7, the side wall of the fixing ring 7 is provided with a notch groove 12, the locking bolt 9 is perpendicular to the notch groove 12 and is threadedly connected to the fixing ring 7.
[0023] As a further improvement, guide angles 13 are provided at the edges on both sides of the connecting platform 4, and the guide angles 13 are inclined outward at 45°. By providing guide angles 13 inclined outward at the edges on both sides of the connecting platform 4, the influence of the connecting sleeve 1 on the flow of the fluid along the insulation pipe is reduced, thereby facilitating the passage of the fluid in the insulation pipe.
[0024] As a further improvement, the inner wall of the fixing ring 7 is provided with raised fixing teeth 14, and the fixing teeth 14 are evenly distributed in a ring shape along the inner wall of the fixing ring 7. By providing evenly distributed fixing teeth 14 on the inner wall of the fixing ring 7, the stability of the connection between the fixing ring 7 and the surface of the insulation pipe is improved, and the fixing ring 7 is prevented from sliding on the surface of the insulation pipe.
[0025] As a further improvement, the inner diameter of the connecting groove 3 is gradually reduced from the outside to the inside, and the tightening ring 8 is made of a metal with lower hardness. By using a metal with lower hardness to make the tightening ring 8, it is convenient to extrude and deform it after embedding it into the connecting groove 3, so that the tightening ring 8 is filled between the insulation pipe and the connecting sleeve 1, thereby enhancing the sealing of the insulation pipe connection.

By providing the traction bolt 16 on the end face of the fixing ring 7, it is convenient to pull the connecting insert 2 and the connecting sleeve 1 against each other, thereby improving the stability of the connection between the connecting insert 2 and the connecting sleeve 1.
[0027] Specifically, a threaded hole 17 is provided on the end face of the connecting sleeve 1, and the traction bolt 16 is connected to the threaded hole 17. By providing threaded holes 17 corresponding to the traction bolts 16 on the end face of the connecting sleeve 1, the convenience of connecting the connecting sleeve 1 and the connecting insert 2 is improved.
[0028] When the utility model is in use, the clamping ring 11 at the end of the tightening ring 8 is embedded in the buckle groove 10 on the inner wall of the fixing ring 7, and then the fixing ring 7 and the tightening ring 8 are sleeved on the surfaces of the thermal insulation pipes on both sides, the fixing position of the fixing ring 7 is adjusted according to the installation requirements, and the locking bolts 9 on the side walls are used to lock it, so as to improve the stability of the connection between the connecting insert 2 and the surface of the thermal insulation pipe, place the connecting sleeve 1 between the thermal insulation pipes, insert the thermal insulation pipe with the connecting insert 2 into the connecting grooves 3 at both ends of the connecting sleeve, and connect the connecting sleeve after the traction bolts 16 pass through the traction holes 15, press the thermal insulation pipe and the connecting insert 2 into the connecting sleeve 1, until the end of the thermal insulation pipe is connected to the embedding groove 5, so as to reduce the probability of leakage of the thermal insulation pipe.

On the one hand, it reduces the requirements for the operating experience of the construction personnel, improves the convenience of the thermal insulation pipe connection construction, and shortens the construction period of the thermal insulation pipe. On the other hand, it reduces the need for the use of special installation equipment, which is convenient for the staff to perform maintenance and replacement in the later stage.
