[0023] 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.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a combined pipe joint, including a kit 1, which is symmetrically arranged. A corrugated expansion pipe 2 is fixedly connected between the kits 1. The kit 1 includes a rubber ring 101, a rubber ring 102, a heat shrinkable sheet 103 and a heat shrinkable belt 104. The heat shrinkable sheet 103 is fixedly installed around an axis between the rubber ring 101 and the rubber ring 102. The heat shrinkable sheet 103 is obliquely arranged, and adjacent heat shrinkable sheets 103 are arranged to overlap each other. A heat shrinkable belt 104 is extended from one of the heat shrinkable sheets 103, and the two sides of the heat shrinkable belt 104 are respectively located at the outer wall positions of the rubber ring 101 and the rubber ring 102.

[0026] Specifically, Figure 1 and Figure 2As shown, the outer side of the rubber ring 101 is open in a bell-shaped manner, so that it is easy to put on the pipe mouth and the more it is put on, the tighter it becomes.

[0027] Specifically, the inner wall of the rubber ring 101 is flush with the inner wall of the rubber ring 102. When the rubber ring 101 is deformed and fixed, the rubber ring 102 does not deform and is directly stuck on the pipe opening to play an installation limit role.

[0028] Specifically, Figure 1 As shown, one third to two thirds of the heat shrinkable sheet 103 body extends out of the outer wall of the rubber ring 101 and the rubber ring 102, and the heat shrinkable sheet 103 covers a large area and has good sealing after heat shrinkage.

[0029] Specifically, the length of the heat shrinkable tape 104 is greater than the circumference of the edge of the rubber ring 101 , and the heat shrinkable tape 104 is long, and can wrap all the heat shrinkable sheets 103 after heat shrinking and deformation.

[0030] Specifically, the bellows expansion tube 2 is made of plastic or rubber, which has low cost, fast production, long stretching deformation, and is easy to restore to its original state.

[0031] Working principle:

[0032] When in use, put a rubber ring 101 of set 1 on the pipe head. As the rubber ring 101 narrows, the rubber ring 101 goes in tighter and tighter until the pipe mouth meets the rubber ring 102 and stops. Although the rubber ring 102 is deformable, it is difficult to put on without a guide, so it will be stuck at the pipe mouth. At this time, wrap the heat shrink tape 104 along the pipe body, and use glue to stick the port position on the heat shrink sheet 103. When the heat shrink tape 104 is wrapped, all the heat shrink sheets 103 are pressed tightly against the pipe. Use The lighter heats the heat shrink tape 104, and the heat shrink sheet 103 and the heat shrink tape 104 are deformed by the heat, and the seal is tightened and covers the pipe. At the same time, the side of the heat shrink tape 104 is also tightly covered on the rubber ring 101 and the rubber ring 102 and fixed. According to this method, the kit 1 is installed at the pipe mouth of another pipe, and the corrugated expansion tube 2 is automatically expanded and adjusted. If you want to enhance the sealing, you can apply a circle of waterproof glue on the side of the heat shrink tape 104, that is, the connection position with the rubber ring 101 and the rubber ring 102, and seal it again.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
