[0028] 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.

[0029] See also Figure 1-4The utility model provides a technical solution: a non-contact pneumatic rotary joint, including a joint body 1, a plastic rotary shell 2 is rotatably connected to the surface of the joint body 1, a sealing clamping tube block 3 is clamped on the surface of the plastic rotary shell 2, a rotary seat 4 is rotatably connected to the inside of the joint body 1, a rotating body 5 is rotatably connected to the inside of the joint body 1, an O-ring 6 is installed on the surface of the rotating body 5, a flat sealing ring 7 is installed inside the joint body 1, a stainless steel gasket 8 is installed on the lower surface of the flat sealing ring 7, a C-type retaining ring 9 is installed inside the joint body 1, and the inside of the joint body 1 The joint body 1 is fixedly connected with a bearing 10, the surface of the joint body 1 is fixedly connected with a connecting frame 11, the surface of the connecting frame 11 is slidably connected with an auxiliary block 12, the surface of the connecting frame 11 is provided with a rectangular groove 13, the surface of the auxiliary block 12 is fixedly connected with a plug plate 22, and the plug plate 22 is slidably connected with the rectangular groove 13. By setting the auxiliary block 12, a supporting effect can be played on the connected pipe, which is convenient for the staff to fix the pipe, does not need to support for a long time, reduces the burden of pipe installation, improves work efficiency, and the auxiliary block 12 is relatively simple and effortless to use. The surface of the auxiliary block 12 is glued with an anti-skid pad 14, and the anti-skid pad 14 is made of rubber material. Because the anti-skid pad 14 is made of rubber material, it can increase the friction between the pipe and the pipe, so that when the pipe is placed on the surface of the auxiliary block 12, it is not easy to move. Four connecting strips 15 are fixedly connected on both sides of the auxiliary block 12, and the four connecting strips 15 are linearly arrayed on the side wall of the auxiliary block 12. The addition of the connecting strip 15 can increase the friction between the fingers of the staff, thereby facilitating the staff to slide the auxiliary block 12. The surface of the connecting frame 11 is fixedly connected with the extension frame 16, and the surface of the extension frame 16 is slidably connected with the plug rod 20. The surface of the plug rod 20 is covered with a spring 21, and the two ends of the spring 21 are respectively fixedly connected to the plug rod 20 and the extension frame 16. A circular groove 19 is provided on the lower surface of the auxiliary block 12, and the size of the circular groove 19 is adapted to the size of one end of the plug rod 20. After the pipeline is installed, the auxiliary block 12 can be slid toward the direction of the joint body 1, and then the plug rod 20 will be inserted into the circular groove 19 under the action of the spring 21 to limit the auxiliary block 12, thereby increasing the functionality of the auxiliary block 12. The surface of the joint body 1 is slidably connected with a limit plate 17, and the limit plate 17 is "U" shaped. After the pipeline is placed, the limit plate 17 can be slid to limit the pipeline, so that the pipeline will not rotate outward, which is convenient for the staff to fix the pipeline. A circular hole 18 is provided on the surface of the limiting plate 17, and the cross section of the circular hole 18 is a trapezoid. Because the cross sections of the circular hole 18 are large and small, it is convenient to quickly connect the fixing screw to the surface of the joint body 1, thereby performing the fixing work and improving the initial fixing efficiency of the pipeline. The surface of the limiting plate 17 is fixedly connected with an inclined surface 23, and the inclined surface 23 can facilitate the limiting plate 17 to quickly limit the pipeline, which facilitates the limiting use of the limiting plate 17.

[0030] Working principle: when using the connector body 1 to connect other pipes, first pull the plug rod 20 to disengage the plug rod 20 from the circular groove 19, and then the staff can slide the auxiliary block 12. There are connecting strips 15 on both sides of the auxiliary block 12. The addition of the connecting strips 15 can increase the friction between the fingers of the staff, making it easier for the staff to slide the auxiliary block 12. Then the plug plate 22 will be inserted into the rectangular groove 13. At this time, the placement of the auxiliary block 12 is completed. The staff can place the pipe to be connected on the surface of the auxiliary block 12. The auxiliary block 12 can support the pipe, and the staff does not need to use a lot of force to support it, which facilitates the fixed installation of the pipe. There is an anti-skid pad 14 on the surface of the auxiliary block 12. Because the anti-skid pad 14 is made of rubber, it can increase the friction between the pipe and make the pipe placed on the surface of the auxiliary block 12 17, and the pipe is not easily moved. After the pipe is placed, the limit plate 17 can be slid to limit the pipe so that the pipe will not rotate outward, which is convenient for the staff to fix the pipe. There is a circular hole 18 on the surface of the limit plate 17. Because the cross-section of the circular hole 18 is large and small, the fixing screws can be quickly connected to the surface of the joint body 1 to fix the pipe, thereby improving the initial fixing efficiency of the pipe. There is an inclined surface 23 on the surface of the limit plate 17. The inclined surface 23 can facilitate the limit plate 17 to quickly limit the pipe, which is convenient for the use of the limit plate 17. After the pipe is installed, the auxiliary block 12 can be slid in the direction of the joint body 1, and then the insertion rod 20 will be inserted into the circular groove 19 under the action of the spring 21 to limit the auxiliary block 12, thereby increasing the functionality of the auxiliary block 12.
