[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a stable connection industrial robotic arm motor dual-channel cooling shaft, including a shaft body 1. The shaft body 1 has a flow channel inside, which allows liquid to circulate inside the shaft body 1. A connecting ring 4 is inserted into the end of the shaft body 1, and the end of the connecting ring 4 is connected to the side wall of the shaft body 1. A sealing component 3 is provided on the inner side wall of the connecting ring 4. A rotary joint 2 is rotatably connected to the side wall of the connecting ring 4, and the rotary joint 2 is used to transport external liquid into the connecting ring 4 and then into the interior of the shaft body 1. Furthermore, a movable block 5 is slidably connected to the inner wall of the connecting ring 4. A limiting groove is provided on the side wall of the connecting ring 4. The movable block 5 is slidably connected inside the limiting groove. Through the setting of the limiting groove, the movable block 5 slides on the inner wall of the connecting ring 4. A clamping plate 7 is fixedly connected to the side wall of the movable block 5. The clamping plate 7 is arc-shaped and has a rubber pad. The inner wall of the rubber pad is in contact with the outer surface of the rotating shaft body 1. The arc-shaped clamping plate 7 can stably fit with the outer surface of the rotating shaft body 1. The setting of the rubber pad improves the stable sealing connection between the clamping plate 7 and the rotating shaft body 1. An adjustment mechanism 6 is provided inside the movable block 5. A water inlet 8 is connected to the side wall of the rotary joint 2. The liquid is transported to the inside of the rotary joint 2 through the water inlet 8. The end of the rotary joint 2 is connected to a water outlet 9. The cooled liquid is output to the inside of the rotary joint 2 through the water outlet 9.

[0019] Reference Figures 3-5 The adjusting mechanism 6 includes a movable plate 61, which is slidably connected inside the movable block 5. A push rod is provided through the side wall of the movable plate 61 and slidably connected to the side wall of the movable block 5. The side wall of the movable plate 61 is elastically connected to the inner side wall of the movable block 5 through a positioning spring 62. Pushing the push rod causes the movable plate 61 to compress the positioning spring 62, causing the positioning spring 62 to deform. When resetting, the rebound of the positioning spring 62 causes the movable plate 61 to slide and reset. An adjusting block 63 is fixedly connected to the side wall of the movable plate 61. The sliding of the movable plate 61 causes the adjusting block 63 to slide inside the movable block 5. The inner side wall of the limiting groove has multiple adjusting slots of equal size and equidistant distribution. The adjusting block 63 passes through the movable block 5 and is inserted into the adjusting slot. The setting of the adjusting slot and the adjusting block 63 ensures that the movable block 5 can be stably limited after sliding to a suitable position.

[0020] Reference Figures 2-3 The sealing assembly 3 includes a return spring 31. One end of the return spring 31 is fixedly connected to the inner wall of the connecting ring 4. The other end of the return spring 31 is fixedly connected to a sealing gasket 32. Pushing the sealing gasket 32 ​​compresses the return spring 31, causing the return spring 31 to deform. During reset, the rebound of the return spring 31 drives the sealing gasket 32 ​​to slide and reset. The sealing gasket 32 ​​is slidably connected inside the connecting ring 4. The sealing gasket 32 ​​is designed to provide a sealing and limiting effect for rotating shaft bodies 1 of different sizes. The sealing gasket 32 ​​is arc-shaped, and the inner wall of the sealing gasket 32 ​​is in contact with the outer surface of the rotating shaft body 1. The sealing gasket 32 ​​and the outer surface of the rotating shaft body 1 are sealed together, improving the sealing connection between the rotating shaft body 1 and the connecting ring 4.

[0021] Working principle: In use, after pushing the sealing gasket 32 ​​and squeezing the return spring 31, one end of the rotating shaft body 1 is placed inside the connecting ring 4. Then, the push on the sealing gasket 32 ​​is released, and the rebound of the return spring 31 causes the sealing gasket 32 ​​to slide and reset, thus sealing the end of the rotating shaft body 1. At the same time, depending on the size of the rotating shaft body 1, the push rod set on the side wall of the moving plate 61 is pushed, which causes the moving plate 61 to squeeze the positioning spring 62 and slide inside the moving block 5, thereby causing the adjusting block 63 to slide into the moving block 5. After sliding to the appropriate position, the push on the push rod is released, and the rebound of the positioning spring 62 causes the moving plate 61 and the adjusting block 63 to slide and reset. The adjusting block 63 is inserted into the connecting ring 4 to improve the stable connection between the clamping plate 7 and the rotating shaft body 1. After the connection is stable, the liquid enters the rotary joint 2 from the inlet 8, and then enters the shaft body 1 after passing through the connecting ring 4. During the liquid flow, the heat generated by the shaft body 1 is carried away and discharged from the outlet 9, which satisfies the heat dissipation effect of the shaft body 1 and improves the safety of the shaft body 1 during use.
