[0025] 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.

[0026] Reference Figure 1 , Figure 5 and Figure 7 , an embodiment of the utility model: a hydraulic coupling comprises a driving shaft connecting disk 1 and a driven shaft connecting disk 2, one side of the driving shaft connecting disk 1 is fixedly connected with a driving shaft connecting sleeve 6, one side of the driven shaft connecting disk 2 is fixedly connected with a driven shaft connecting sleeve 7, both sides of the inner parts of the driving shaft connecting sleeve 6 and the driven shaft connecting sleeve 7 are threadedly connected with threaded rods 8, one end of multiple threaded rods 8 are threadedly connected with moving plates 9, both sides of multiple moving plates 9 are fixedly connected with limiting components, the limiting components are used to limit the moving plates 9, the limiting components comprise sliders 10, two sliders 10 are fixedly connected with both sides of the moving plates 9, multiple sliders 10 are slidably connected to the inside of sliding grooves 11, sliding grooves 11 are provided on both sides of the inner parts of the driving shaft connecting sleeve 6 and the driven shaft connecting sleeve 7, both sides of multiple moving plates 9 are fixedly connected with connecting rods 12, the other end of the connecting rods 12 is fixedly connected with clamping members 13, and multiple clamping members 13 are slidably connected to the insides of the driving shaft connecting sleeve 6 and the driven shaft connecting sleeve 7.

[0027] The two ends of the rotating shaft need to be inserted into the driving shaft connecting sleeve 6 and the driven shaft connecting sleeve 7 respectively. When the threaded rod 8 rotates, it drives the movable plate 9 to move on the predetermined track. As the movable plate 9 moves, the slider 10 slides inside the slide groove 11. Under the guidance of the slider 10, the movement of the movable plate 9 further drives the movement of the connecting rod 12. The movement of the connecting rod 12 directly determines the position of the clamping piece 13. As the connecting rod 12 moves, the two clamping pieces 13 slowly approach each other and tightly clamp the rotating shaft in the middle.

[0028] Reference Figure 1-Figure 3 The outside of the driving shaft connecting disk 1 is fixedly connected with a mounting seat 3, the outside of the driven shaft connecting disk 2 is fixedly connected with an insert block 4, multiple insert blocks 4 are slidably connected to the inside of the mounting seat 3, multiple mounting seats 3 are provided with slots 5, and multiple insert blocks 4 are slidably connected to the inside of the slots 5.

[0029] When installing the coupling, it is first necessary to ensure the precise alignment between the driving shaft connection plate 1 and the driven shaft connection plate 2. Once the alignment is completed, the insert block 4 will be cleverly turned into the slot 5 inside the mounting seat 3, firmly locking the driving shaft connection plate 1 and the driven shaft connection plate 2 together.

[0030] Reference Figure 2 , Figure 4 and Figure 6 A push rod 15 is slidably connected to the inside of the driven shaft connecting disk 2, and a positioning block 14 is fixedly connected to the upper part of the push rod 15, and a push plate 17 is fixedly connected to the bottom of the push rod 15. Insert rods 18 are fixedly connected to both sides of the upper part of the push plate 17. Oil filling holes 19 are opened on both sides of the inside of the driven shaft connecting disk 2, and the two insert rods 18 are slidably connected to the inside of the oil filling holes 19. A compression spring 16 is sleeved on the outside of the push rod 15, one end of the push rod 15 is fixedly connected to the upper part of the driven shaft connecting disk 2, and the other end of the push rod 15 is fixedly connected to the bottom of the positioning block 14. Sealing plugs 20 are provided inside the two oil filling holes 19, and the push plate 17 and the insert rod 18 are slidably connected to the inside of the driven shaft connecting disk 2.

[0031] Pull up the two sealing plugs 20. These two sealing plugs 20 not only prevent the leakage of lubricating oil, but also provide a convenient entrance for the oil filling operation. Once the sealing plugs 20 are opened, the next step is to press down the positioning block 14. The positioning block 14 is a key component in the oil filling mechanism. When the positioning block 14 is pressed down hard, it will gradually exert pressure on the compression spring 16 to shrink it. As the positioning block 14 moves downward, it drives the push rod 15 to move. The push rod 15 transmits the force of the positioning block 14 to the push plate 17. The push plate 17 is another important component in the oil filling mechanism. Its movement directly determines the opening and closing of the oil filling hole 19. When the push plate 17 is in When the push rod 15 moves downward, it further drives the insertion rod 18 to move downward. The insertion rod 18 was originally inserted into the oil filling hole 19 to close the oil filling hole 19. As the push plate 17 moves downward, the insertion rod 18 gradually moves out from the inside of the oil filling hole 19, revealing a spacious oil filling channel. At this time, oil can be filled into the oil filling hole 19. After the oil filling is completed, it is only necessary to loosen the positioning block 14. Under the strong elastic action of the compression spring 16, the push plate 17 starts to drive the insertion rod 18 to move upward and gradually return to the initial position. The insertion rod 18 is reinserted into the oil filling hole 19 to close the oil filling channel and prevent the leakage of the lubricating oil.

[0032] Working principle: When installing the coupling, align the driving shaft connection disk 1 and the driven shaft connection disk 2, and rotate the insert block 4 into the slot 5 inside the mounting seat 3 to lock the driving shaft connection disk 1 and the driven shaft connection disk 2. Then, insert the two ends of the rotating shaft into the driving shaft connection sleeve 6 and the driven shaft connection sleeve 7, and rotate multiple threaded rods 8. When the threaded rods 8 rotate, they drive the moving plate 9 to move, and the moving plate 9 drives the slider 10 to slide inside the slide groove 11. Under the action of the slider 10, the moving plate 9 moves to drive the connecting rod 12 to move, and the connecting rod 12 moves to drive the clamping piece 13 to move, so that the two clamping pieces 13 are close to each other, and the rotating shaft is clamped and fixed, thereby facilitating the installation and disassembly of the rotating shaft, making maintenance and replacement work more efficient and reducing equipment downtime. The working efficiency of the whole system is improved. When oil filling is needed, the two sealing plugs 20 are pulled upwards, and the positioning block 14 is pressed downwards to make the positioning block 14 squeeze the compression spring 16. The positioning block 14 moves downwards to drive the push rod 15 to move downwards, and the push rod 15 drives the push plate 17 to move downwards. The push plate 17 moves downwards to drive the insertion rod 18 to move downwards, so that the insertion rod 18 is moved out from the inside of the oil filling hole 19, and oil can be filled into the inside of the oil filling hole 19. After the oil filling is completed, the positioning block 14 is released, and under the elastic action of the compression spring 16, the push plate 17 drives the insertion rod 18 to restore its position, thereby facilitating oil filling, making the daily maintenance of the hydraulic coupling simpler, effectively preventing damage caused by insufficient lubrication, and reducing maintenance costs.
