As shown in fig. 5, the pipe connection structure 100 of the pipe joint provided by the present invention is a pipe connection end B, and the pipe connection structure 100 of the pipe joint is used for connecting the joint with a hose 200. The hose 200 described above in the present application is preferably a single layer nylon tube.
Specifically, the connecting tube structure 100 of the pipe joint of the present application includes a connecting body 110, a movable sleeve 120, a sealing sleeve 130, and a sealing ring 140. Wherein, the movable sleeve 120 is rotatably sleeved on the connecting main body 110, and the movable sleeve 120 is in clearance fit with the connecting main body 110. A sealing boot 130 is secured to the end of the connecting body 110, and a sealing ring 140 is disposed within a sealing groove of the sealing boot. The hose 200 is fitted over the movable sleeve 120 and the sealing sleeve 130. The sealing ring is arranged between the sealing sleeve and the hose, as shown in fig. 5. The inventive principle of the present application is as follows:
in order to realize that the connecting pipe structure of the pipeline joint and the hose 200 rotate under a smaller torsion moment, the friction resistance between the connecting pipe structure of the hose 200 and the pipeline joint needs to be reduced, and the application realizes the pipeline joint by reducing the contact area. The connecting pipe structure of the pipeline joint in the prior art is shown in figure 1, and when the pipeline joint rotates, the frictional resistance at three bamboo joints needs to be overcome. After the connecting pipe structure of the pipeline joint is connected with the hose 200, as shown in fig. 5, when the connecting pipe structure of the pipeline joint rotates, the movable sleeve 120 of the connecting pipe structure 100 of the pipeline joint rotates together with the hose 200, the movable sleeve 120 and the connecting main body 110 are in clearance fit, the friction force is small, the friction resistance to be overcome during rotation is mainly the friction resistance at the sealing sleeve 130, and the required torque is small.
According to the pipeline joint connecting structure, the connecting pipe structure of the pipeline joint is adjusted, so that the movable sleeve 120 is rotatably sleeved on the connecting main body 110 of the connecting pipe structure of the pipeline joint, and the friction force during rotation can be reduced. Therefore, when the hose is assembled and used, the relative angle between the joint and the hose 200 can be adjusted under the condition of smaller torsion, the direction of the joint can be rotated by using smaller torsion, the assembly angle can be adjusted, and the assembly is convenient.
Further, the movable sleeve 120 of the embodiment of the present application is a movable bamboo joint, and a first bamboo joint structure is formed on an outer side wall of the movable bamboo joint. As shown in fig. 6, the first bamboo joint structure includes at least two bamboo joints. The bamboo-like inverted teeth of the first bamboo structure may enable the hose 200 to be quickly connected.
Further, the sealing sleeve 130 of the embodiment of the present application is a sealing bamboo joint. A second bamboo joint structure for quick connection of the hose 200 is formed on an outer side wall of the sealing bamboo joint. The sealing sleeve 130 abuts against the sealing ring 140 and the hose 200 to realize sealing, and on the other hand, as shown in fig. 7, the sealing sleeve 130 can limit the axial movement of the movable sleeve 120, and the tensile strength of the assembly of the pipeline joint 100 and the hose 200 is not affected.
