[0021] 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.

[0022] See Figures 1-5 As shown, the present invention proposes a cam divider with a sealing structure, comprising: a cam divider 1 and a sealing mechanism 2.

[0023] The sealing mechanism 2 includes a top plate 24, a sealing shaft 25, and a fixing block 26.

[0024] The cam divider 1 has a mounting groove 21; the inner wall of the mounting groove 21 has a first limiting groove 22; a top plate 24 is disposed within the first limiting groove 22; a sealing shaft 25 is disposed within the mounting groove 21; and fixing blocks 26 are respectively disposed on the outer wall of the sealing shaft 25. A first spring 23 is disposed within the first limiting groove 22, and the other end of the first spring 23 is connected to the top plate 24. The inner wall of the sealing shaft 25 has a sealing groove 27, and a sealing gasket 28 is disposed inside the sealing groove 27.

[0025] Specifically, during the installation of the cam divider 1, the cam 12 is installed into the housing 11, and then the sealing shaft 25 is sleeved on the outside of the connecting rod of the cam 12. Then, it slides downward so that the fixing block 26 on the outer wall of the sealing shaft 25 is inserted into the mounting groove 21 and rotated, so that the fixing block 26 on the outer wall of the sealing shaft 25 is engaged in the first limiting groove 22. At this time, the sealing gasket 28 in the sealing groove 27 will seal the connection between the sealing shaft 25 and the connecting rod of the cam 12, and at the same time, the sealing shaft 25 will seal the gap between the connecting rod of the cam 12 and the housing 11.

[0026] The cam divider 1 includes a housing 11, a cam 12, and an output shaft 13. The cam 12 is installed inside the housing 11; the output shaft 13 is disposed on the outer wall of the housing 11.

[0027] Specifically, during use, the cam 12 converts continuous input rotation into intermittent output motion through meshing motion with the output shaft 13.

[0028] In one embodiment of this application, such as Figure 1 and Figure 4As shown, a connecting assembly 3 is provided on the output shaft 13. The connecting assembly 3 includes a mounting shell 31, sliders 34, and a fixing assembly 35. The mounting shells 31 are respectively fitted onto the outside of the output shaft 13; the inner wall of the mounting shell 31 has a sliding groove 32; the inner wall of the sliding groove 32 has a fixing groove 33; the sliders 34 are respectively disposed on the outer wall of the output shaft 13; and the fixing assembly 35 is provided on the inner wall of the sliding groove 32.

[0029] The fixing component 35 includes a limiting block 352 and a control ring 354. A connecting hole 351 is provided on the inner wall of the slide groove 32; the limiting blocks 352 are respectively disposed inside the corresponding slide grooves 32, and the limiting blocks 352 pass through the connecting holes 351 and are connected to the control ring 354; a second limiting groove 353 is provided on the outer wall of the mounting shell 31, and the connecting hole 351 passes through the second limiting groove 353. A second spring 355 is disposed inside the connecting hole 351, and the other end of the second spring 355 is connected to the limiting block 352.

[0030] Specifically, during use, the sliding groove 32 inside the mounting housing 31 is aligned with the slider 34 on the outer wall of the output shaft 13 and inserted. At this time, the slider 34 will press the limiting block 352 into the connecting hole 351. Then, the output shaft 13 is rotated so that the slider 34 on the outer wall of the output shaft 13 is stuck in the fixing groove 33. At this time, the limiting block 352, which is no longer pressed by the slider 34, will be popped out by the second spring 355 to fix the slider 34 in the fixing groove 33.

[0031] In one embodiment of this application, such as Figure 4 As shown, the outer wall of the output shaft 13 is fitted with sealing rings 4, and the inner wall size of the sealing rings 4 matches the outer wall size of the output shaft 13.

[0032] It is understood that the function of the sealing ring 4 described in this embodiment is to seal the connection between the output shaft 13 and the housing 11.

[0033] The working principle of this utility model is as follows: During the installation of the cam divider 1, the cam 12 is installed into the housing 11, and then the sealing shaft 25 is sleeved on the outside of the connecting rod of the cam 12. Then, it slides downward so that the fixing block 26 on the outer wall of the sealing shaft 25 is inserted into the mounting groove 21 and rotated, so that the fixing block 26 on the outer wall of the sealing shaft 25 is stuck into the first limiting groove 22. At this time, the sealing gasket 28 in the sealing groove 27 will seal the connection between the sealing shaft 25 and the connecting rod of the cam 12, and at the same time, the sealing shaft 25 will seal the gap between the connecting rod of the cam 12 and the housing 11.

[0034] In summary, when installing the cam divider 1, the gaps between the cam 12 and the output shaft 13 and the housing 11 are filled by the sealing shaft 25 and the sealing ring 4, thereby preventing the lubricating oil inside the housing 11 from leaking out from the connection.
