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-Figure 7 , the utility model provides a technical solution:

[0030] Embodiment 1:

[0031] A split combined gear housing comprises an upper housing 1, a lower housing 2 and a tilting tube 3, wherein the upper housing 1 is fixedly mounted on the top of the lower housing 2, the tilting tube 3 is fixedly connected to one side of the lower housing 2, and a sealing mechanism is arranged on the top of the tilting tube 3;

[0032] One implementation method of this embodiment is: the sealing mechanism is arranged on the sealing cover 4 at the top of the inclined tube 3, the sealing cover 4 is connected to the inclined tube 3 by a traction rope 5, the inner wall of the sealing cover 4 is fixedly connected with a first sealing ring 6, the circumferential side fixed sleeve of the inclined tube 3 is provided with a second sealing ring 7, and the circumferential side of the sealing cover 4 is provided with a stabilizing mechanism.

[0033] In this embodiment, it is considered that the inclined tube 3 used for adding lubricating oil to the inside of the split combined gear box body is thread-sealed by a sealing plug, and the thread itself is easy to wear, and lubricating oil is easy to leak after wear, which is not conducive to the use of the user. Therefore, by setting a sealing mechanism, after the oil is added from the inclined tube 3, the sealing cover 4 can be pushed downward by aligning the position of the sealing cover 4 with the pipe opening of the inclined tube 3, so that the sealing cover 4 is stuck at the pipe opening of the inclined tube 3, and at the same time, the first sealing ring 6 encounters the second sealing ring 7 during the downward movement, and the two are squeezed and deformed, and the first sealing ring 6 moves to the bottom position of the second sealing ring 7, and the number of the first sealing ring 6 and the second sealing ring 7 is several, and the multi-layer sealing can effectively prevent the leakage of lubricating oil;

[0034] The invention solves the problem that the inclined tube 3 used for adding lubricating oil to the inside of the split combined gear box is thread-sealed by a sealing plug, and the thread itself is easy to wear, and lubricating oil is easy to leak after wear, which is not conducive to user use.

[0035] A push block 23 is disposed on the top of the housing 8 , and one side of the push block 23 is fixedly connected to the surface of the sealing cover 4 .

[0036] In this embodiment, the push block 23 is provided to provide a lever point for the user to install or remove the sealing cover 4 , so as to facilitate moving the sealing cover 4 .

[0037] The top and bottom of the first sealing ring 6 and the second sealing ring 7 are both arc-shaped and made of silicone.

[0038] In this embodiment, by setting the top and bottom of the first sealing ring and the second sealing ring 7 to be arc-shaped, when the first sealing ring 6 contacts the second sealing ring 7, the arc portion contacts first, which makes it easier for deformation to occur, so that the first sealing ring 6 can be more easily moved to the bottom of the second sealing ring 7, and the sealing cover 4 can also be more convenient to remove.

[0039] Embodiment 2:

[0040] On the basis of Example 1, the sealing mechanism in this embodiment can seal the tilt tube 3 to avoid leakage. However, considering that the gears inside the split combined gear box body will vibrate when rotating, if the sealing cover 4 is not restricted, the sealing cover 4 will fall off due to vibration, causing leakage of the lubricating oil. The stabilizing mechanism in this application includes two shells 8 fixedly connected to the circumference of the sealing cover 4, and a snap-in groove 9 is provided on the top of the shell 8. Two positioning blocks 10 are symmetrically fixedly connected to the circumferential side of the sealing cover 4. The positioning blocks 10 are opposite to the shell 8, and the top of the positioning block 10 is fixedly connected with a snap-in block 11, and a positioning mechanism is provided inside the shell 8.

[0041] In this embodiment, it is taken into consideration that the gears inside the split combined gear box body will vibrate when rotating. If the sealing cover 4 is not restricted, the sealing cover 4 will fall off due to the vibration, causing leakage of the lubricating oil. Therefore, by providing a stabilizing mechanism, when installing the sealing cover 4, the position of the clamping block 11 and the clamping groove 9 can be aligned, and the sealing cover 4 can be pushed downward so that the clamping block 11 enters the inside of the clamping groove 9, thereby restricting the housing 8 and the sealing cover 4, improving the stability of the sealing cover 4, and preventing the sealing cover 4 from falling off due to vibration.

[0042] The positioning mechanism includes a linkage block 12 movably connected to the inside of the shell 8, a pressing rod 24 is fixedly connected to one side of the linkage block 12, one end of the pressing rod 24 passes through the outside of the shell 8, and two extrusion blocks 13 are fixedly connected to the side of the linkage block 12 away from the pressing rod 24. An extrusion groove 14 is provided on the top of the extrusion block 13, and an extrusion rod 15 is arranged inside the extrusion groove 14. A transmission block 16 is fixedly connected to the top of the extrusion rod 15, a moving block 17 is fixedly connected to one side of the transmission block 16, and a positioning rod 18 is fixedly connected to the side of the moving block 17 close to the clamping block 11, one end of the positioning rod 18 passes through the inside of the clamping groove 9, and positioning holes 19 used in conjunction with the positioning rod 18 are provided on both sides of the clamping block 11.

[0043] In this embodiment, by setting a positioning mechanism, the positioning rod 18 in the positioning mechanism can enter the positioning hole 19 to limit the housing 8 and the sealing cover 4 again, further improving the stability of the connection between the sealing cover 4, preventing it from falling off due to vibration, and effectively avoiding leakage of lubricating oil.

[0044] A sliding block 20 is fixedly connected to one side of the moving block 17 , and a sliding groove 21 for use with the sliding block 20 is formed on the inner wall of the housing 8 .

[0045] In this embodiment, by providing the sliding block 20 and the sliding groove 21 , the moving track of the moving block 17 and the positioning rod 18 can be limited so that they can only move along the track of the sliding block 20 and the sliding groove 21 .

[0046] A spring 22 is fixedly connected to one side of the moving block 17 , and one end of the spring 22 is fixedly connected to the inner wall of the housing 8 .

[0047] In this embodiment, by providing the spring 22 , the elastic force generated by the spring 22 can be used to reset the moving block 17 and the positioning rod 18 , so that the positioning rod 18 can accurately enter the interior of the positioning hole 19 .

[0048] Working principle: When the user needs to refuel, the two pressing rods 24 are pressed to drive the linkage block 12 to move, and the linkage block 12 drives the extrusion block 13 to move. When the extrusion block 13 moves, the inner wall bevel of the extrusion groove 14 contacts the surface of the extrusion rod 15, and the transmission block 16 and the moving block 17 are pushed and moved along the track of the sliding block 20 and the sliding groove 21 to the side away from the clamping block 11. The moving block 17 drives the positioning rod 18 to leave the inside of the positioning hole 19. At this time, the pushing block 23 is pushed upward, which can drive the sealing cover 4 to leave the surface of the tilting tube 3, and inject lubricating oil into the tilting tube 3;

[0049] Then, align the positions of the clamping block 11 and the clamping groove 9, push the sealing cover 4 downward, so that the clamping block 11 enters the clamping groove 9 and the sealing cover 4 is clamped at the mouth of the inclined tube 3. At the same time, the first sealing ring 6 encounters the second sealing ring 7 during the downward movement, and the two are squeezed and deformed. The first sealing ring 6 moves to the bottom position of the second sealing ring 7, and the number of the first sealing ring 6 and the second sealing ring 7 is several, and the multi-layer sealing can effectively prevent the leakage of lubricating oil;

[0050] After that, the pressing block is released, and the elastic force generated by the spring 22 will drive the moving block 17 and the positioning rod 18 to move along the trajectory of the sliding block 20 and the sliding groove 21, so that the positioning rod 18 enters the interior of the positioning hole 19, further improving the stability of the connection of the sealing cover 4, so that it cannot fall off due to vibration, and effectively avoiding leakage of lubricating oil.
