DETAILED DESCRIPTION

[0020] 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 of 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.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 The figure shows an insulating pipe waterproof joint structure, including a joint assembly 1 for connecting insulating pipe fittings, the joint assembly 1 includes a joint 101 and a joint 102, an internal threaded tube 103 is installed at the lower end of the joint 101, an external threaded tube 106 is fixedly installed at the upper end of the joint 102, and the external threaded tube 106 and the joint 102 are an integrally formed structure, and the outer sides of the joint 101, the joint 102 and the internal threaded tube 103 are all provided with a plurality of convex strips 2 equidistantly distributed around the circumference; a sealing assembly 4 is used to enhance the sealing performance between the joint 101 and the joint 102, and the sealing assembly 4 is installed between the joint 101 and the joint 102, and is located on the inner side of the external threaded tube 106.

[0023] See also Figure 3 , Figure 4 The connection between the internal threaded tube 103 and the external threaded tube 106 is a threaded connection. The internal threaded tube 103 is threadedly sleeved on the outside of the external threaded tube 106. The upper end of the internal threaded tube 103 is fixedly connected with an embedded ring 104. The lower end of the joint 101 is provided with an embedding groove 105. The cross-sectional shapes of the embedded ring 104 and the embedding groove 105 are equal. The internal threaded tube 103 is rotatably connected to the joint 101 through the embedded ring 104 and the embedding groove 105.

[0024] The working principle capable of performing length compensation between pipelines: when two sections of insulating pipes are connected by the joint assembly 1, when the distance between the two sections of insulating pipes exceeds the length of the joint assembly 1, and the exceeding distance is relatively short, a person holds the joint 101 with one hand and rotates the internal threaded pipe 103 with the other hand. Under the condition that the internal threaded pipe 103 is threadedly connected to the external threaded pipe 106, when the person rotates the internal threaded pipe 103, the distance between the joint 101 and the joint 2 102 can be increased, thereby lengthening the overall length of the joint assembly 1, so that the length compensation between the two sections of insulating pipes can be performed by the joint assembly 1, making the joint assembly 1 more flexible to use.

[0025] Embodiment 2

[0026] See also Figure 3The present embodiment further explains the first embodiment, the sealing assembly 4 includes a bellows 401 movably fitted with the inner wall of the external threaded tube 106, the bellows 401 is made of a rubber material, the bellows 401 made of rubber material has strong wear resistance, both ends of the bellows 401 are fixedly connected with rubber gaskets 402, and the rubber gasket 402 and the bellows 401 are an integrally formed structure, the rubber gasket 402 can enhance the sealing between the bellows 401 and the joint 1 101 and the joint 2 102.

[0027] See also Figure 1 , Figure 4 The lower ends of the connector 101 and the connector 2 102 are provided with an embedding groove 2 5 corresponding to the rubber gasket 402, and the rubber gasket 402 is fixedly embedded in the embedding groove 2 5. The cross-sectional shapes of the embedding groove 2 5 and the rubber gasket 402 are equal. The outer sides of the connector 101 and the connector 2 102 are both threadedly sleeved with nuts 3, and the nuts 3 facilitate the connection between the insulating tube and the connector assembly 1.

[0028] In this embodiment: when the internal threaded tube 103 is rotated to adjust the distance between the joint 1 101 and the joint 2 102 and change the overall length of the joint assembly 1, the rubber bellows 401 located inside the external threaded tube 106 will expand or fold accordingly, and the rubber gaskets 402 at the two sections of the rubber bellows 401 are fixedly embedded in the joint 1 101 and the joint 2 102 respectively, which not only enables the sealing assembly 4 to change its length arbitrarily with the joint assembly 1, but also helps to make the sealing performance between the joint 1 101 and the joint 2 102 higher, so that the waterproof effect of the joint assembly 1 is good.
