[0002] In mechanical equipment, when two rotating bodies are not on the same horizontal line, an unbalanced transmission method is required. Currently, the transmission methods are mainly divided into universal joint transmission and coupling transmission. The method of connecting two universal joints with a shaft in the middle is limited in many small equipment or short-distance transmissions due to factors such as the need for a certain distance and the large volume of the rotating parts. When using coupling transmission, the two coupling discs need to be linked by plastic rods or chains.

[0003] Most automotive universal drive shafts on the market require workers to disassemble them and apply lubricant after prolonged use, which makes the process quite cumbersome. Therefore, there is a need for an automotive universal drive shaft that is easy to lubricate. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This automotive universal drive shaft, designed for easy lubrication, features a rubber gasket and a sealing piston. The rubber gasket is secured to the periphery of the universal drive shaft module via a locking groove and locking plate. The inner side of the rubber gasket forms a sealed cavity, allowing lubricant to be poured directly into the gasket through the injection port for lubrication.

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. Example

[0021] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an automotive universal drive shaft that is easy to inject lubricating oil includes a universal drive shaft module 1 and a preparation mechanism mounted on the periphery of the universal drive shaft module 1. The preparation mechanism includes auxiliary components and fixing components.

[0022] The auxiliary components include a locking groove 2, a locking plate 3, a rubber pad 4, an injection port 5, a sealing piston 6, a closing cover 7, and a handle 8. The locking groove 2 is installed on the side wall of the universal drive shaft module 1. The locking plate 3 is installed on the inner side of the locking groove 2. The rubber pad 4 is installed on the outer side of the locking plate 3. The injection port 5 is installed on the side wall of the rubber pad 4. The sealing piston 6 is installed on the inner side of the injection port 5. The closing cover 7 is installed on one end of the sealing piston 6. The handle 8 is installed on the other end of the closing cover 7.

[0023] The fixing assembly includes a connecting plate 9, a hollow plate 10, a first bearing 11, a connecting column 12, a hand crank 13, a first bevel gear 14, a second bevel gear 15, a threaded column 16, a second bearing 17, a threaded groove 18, a support frame 19, a slider 20, a slide rail 21, and a clamping plate 22. The connecting plate 9 is mounted on the other side wall of the universal drive shaft module 1. A hollow plate 10 is mounted on one side of the connecting plate 9. A first bearing 11 is mounted on the side wall of the hollow plate 10. A connecting column 12 is mounted on the inner side of the first bearing 11. One side of the connecting column 12... A hand crank 13 is installed at one end, a first bevel gear 14 is installed at the other end of the connecting column 12, a second bevel gear 15 is installed on one side of the first bevel gear 14, a threaded column 16 is installed at one end of the second bevel gear 15, a second bearing 17 is installed at the other end of the threaded column 16, a threaded groove 18 is installed around the threaded column 16, a support frame 19 is installed outside the threaded groove 18, a slider 20 is installed on the side wall of the support frame 19, a slide rail 21 is installed on the outside of the slider 20, and a clamping plate 22 is installed on the other side of the support frame 19.

[0024] The rubber pad 4 forms an engaging structure with the universal drive shaft module 1 through the engaging groove 2 and engaging plate 3. The sealing piston 6 forms a closed structure with the rubber pad 4 through the injection port 5. The handle 8 forms a fixed structure with the sealing piston 6 through the closing cover 7. The engaging groove 2 and engaging plate 3 can engage the rubber pad 4 on the outside of the universal drive shaft module 1. The inside of the rubber pad 4 can form a sealed cavity. Lubricating oil can be poured directly into the inside of the rubber pad 4 through the injection port 5 to lubricate the universal drive shaft. The injection port 5 can be closed by the sealing piston 6 to prevent the lubricating oil from flowing out.

[0025] The connecting column 12 forms a rotating structure with the hollow plate 10 through the first bearing 11, and the hand handle 13 forms a fixed structure with the first bevel gear 14 through the connecting column 12. The first bevel gear 14 and the second bevel gear 15 form a meshing structure, and the second bevel gear 15 and the threaded column 16 form a fixed structure. By rotating the hand handle 13 with external force, the first bevel gear 14 can be driven to rotate. Through the meshing structure of the first bevel gear 14 and the second bevel gear 15, the rotation of the first bevel gear 14 can cause the second bevel gear 15 to rotate, which indirectly drives the threaded column 16 to rotate.

[0026] The threaded column 16 forms a rotating structure with the hollow plate 10 through the second bearing 17, and the threaded column 16 forms a threaded connection with the support frame 19 through the threaded groove 18. The support frame 19 forms a sliding structure with the slide rail 21 through the slider 20, and the support frame 19 forms a fixed structure with the clamping plate 22. Through the threaded connection of the threaded column 16 and the threaded groove 18, the rotation of the threaded column 16 can move the support frame 19, thereby driving the clamping plate 22 to move. The relative movement of the two sets of clamping plates 22 can form a clamping assembly to clamp and fix the rubber pad 4. This device also facilitates the disassembly and installation of the rubber pad 4 for maintenance. Example

[0027] like Figure 1 and Figure 2 As shown, this embodiment further illustrates Example 1, with a fixing plate 23 installed at one end of the universal drive shaft module 1, and a threaded bolt 24 installed on the inner side of the fixing plate 23.

[0028] The universal drive shaft module 1 and the fixing plate 23 form a fixed structure, and the fixing plate 23 forms a detachable structure through the threaded bolts 24, which can be used to install and fix the universal drive shaft module 1.

[0029] Working principle: First, the operator needs to install and fix the universal drive shaft module 1 using the threaded bolt 24. By turning the handle 13 with external force, the first bevel gear 14 can be rotated. The rotation of the first bevel gear 14 can cause the second bevel gear 15 to rotate, which indirectly drives the threaded column 16 to rotate. The rotation of the threaded column 16 can move the support frame 19, which in turn can move the clamping plate 22. The relative movement of the two sets of clamping plates 22 can form a clamping assembly to clamp and fix the rubber pad 4. This device also facilitates the disassembly and installation of the rubber pad 4 for maintenance. Then, the rubber pad 4 can be engaged with the periphery of the universal drive shaft module 1 through the engaging groove 2 and engaging plate 3. The inner side of the rubber pad 4 can form a sealed cavity. Lubricating oil can be poured directly into the interior of the rubber pad 4 through the injection port 5 to lubricate the universal drive shaft. The injection port 5 can be closed by the sealing piston 6 to prevent the lubricating oil from flowing out.
