It can be understood that the foregoing solution can be used in the scenario of connecting the elbow joint, and can also be used to solve the problem of fixing the pipe bodies on both sides of the elbow joint.

[0021] For this specific embodiment, the number of the quick-connect blocks 102 is multiple. The multiple quick-connect blocks 102 are respectively fixedly connected to the elbow pipe 101 and are respectively located outside the elbow pipe 101. The quick-connect cylinder 103 is threadedly connected to the elbow pipe 101 and is located outside the elbow pipe 101. The sealing gasket 104 is fixedly connected to the quick-connect block 102 and is located inside the elbow pipe 101. The number of the rotating plates 105 is two. The two rotating plates 105 are respectively fixedly connected to the quick-connect cylinder 103 and are respectively located outside the quick-connect cylinder 103. The fixing assembly and the connecting assembly are respectively connected to the elbow pipe 101. The quick-connect block 102 is made of rubber. The quick-connect cylinder 103 is used to control the quick-connect block 102. The sealing gasket 104 is used to seal the gap when the connecting assembly is fixed to the elbow pipe 101. When connecting the pipeline, after fixing the connecting pipe 113 to an external pipeline, insert the connecting pipe 113 into the elbow pipe 101. Through the rotating plate 105, it is convenient to rotate the quick-connect cylinder 103. When rotating the quick-connect cylinder 103, the quick-connect cylinder 103 moves outward along the elbow pipe 101, squeezing the quick-connect block 102 inward. The connecting pipe 113 is fixed by the fixing seat 106 and the limiting strip 107 inside the quick-connect block 102, making the elbow joint easy to install and disassemble quickly.

[0022] Among them, the number of the fixing seats 106 is multiple. The multiple fixing seats 106 are respectively fixedly connected to the quick-connect block 102 and are respectively located inside the elbow pipe 101. The number of the limiting strips 107 is multiple. The multiple limiting strips 107 are respectively fixedly connected to the quick-connect block 102 and are respectively located outside the fixing seat 106. The fixing seat 106 and the limiting strip 107 are made of rubber. When the quick-connect cylinder 103 squeezes the quick-connect block 102, it is in contact with the connecting pipe 113 through the fixing seat 106 and the limiting strip 107, facilitating the fixing of the connecting pipe 113.

[0023] Secondly, the surface of the quick-connect block 102 is provided with quick-connect threads 108 that mesh with the quick-connect cylinder 103. The inner side of each fixing seat 106 is respectively provided with two fixing grooves 109. The quick-connect threads 108 mesh with the internal threads of the quick-connect cylinder 103, making it convenient to control the quick-connect block 102 when the quick-connect cylinder 103 rotates. The fixing groove 109 provides a limiting function for the fixing strip 114.

[0024] Again, the fixed tube 110 is threadedly connected to the bent tube 101 and is located at one end of the bent tube 101 away from the quick-connect block 102. The guide strip 111 is fixedly connected to the fixed tube 110 and is located between the fixed tube 110 and the bent tube 101. The sealing tube 112 is fixedly connected to the fixed tube 110 and is located on the outside of the fixed tube 110. The fixed tube 110 is connected to an external pipeline. After the connection is completed, the bent tube 101 is rotated to connect the fixed tube 110 to the bent tube 101. The guide strip 111 provides guidance and limiting functions for the fixed tube 110, and the sealing tube 112 seals the gap between the fixed tube 110 and the bent tube 101.

[0025] Finally, the connecting pipe 113 is detachably connected to the bent pipe 101 and is located on the inner side of the quick-connect block 102. There are two fixing strips 114. The two fixing strips 114 are respectively fixedly connected to the connecting pipe 113 and are respectively located inside the fixing groove 109. The baffle 115 is fixedly connected to the connecting pipe 113 and is located on the outer side of the connecting pipe 113. The connecting pipe 113 is connected to an external pipeline. The fixing strip 114 provides a limiting function for the connecting pipe 113. The baffle 115 is used to fix the connecting pipe 113 so that the fixing strip 114 can be easily inserted into the fixing groove 109.

[0026] When using the elbow joint of this embodiment, the quick-connect block 102 is made of rubber, the quick-connect tube 103 is used to control the quick-connect block 102, and the sealing gasket 104 is used to seal the gap when the connection component is fixed to the elbow 101. When connecting the pipeline, after the connecting tube 113 is fixed to the external pipeline, the connecting tube 113 is inserted into the elbow 101, and the quick-connect tube 103 is convenient to rotate through the rotating plate 105. When the quick-connect tube 103 is rotated, the quick-connect tube 103 moves outward along the elbow 101 to squeeze the quick-connect block 102 inward, and the connecting tube 113 is fixed by the fixing seat 106 and the limiting strip 107 inside the quick-connect block 102, so that the elbow joint is easy to install and disassemble quickly, which solves the problem that the two ends of the elbow joint are the same type of joints. After the joint on one side is installed, the joint is not easy to rotate, resulting in inconvenience in installing the joint on the other side.
