[0024] See also Figures 1 to 5 , the utility model provides a technical solution:

[0025] An automatically lubricated motor shaft comprises a shaft body 1, a surface of the shaft body 1 is provided with an embedding groove 2, a sealing mechanism 3 is installed in the middle of the shaft body 1, a pull rope 4 is connected inside a protective plug cover 31 in the sealing mechanism 3, the other side of the pull rope 4 is connected to a lubrication mechanism 5, and a lubricating oil storage tank 6 is provided inside the shaft body 1.

[0026] In the specific implementation process, Figure 4 The sealing mechanism 3 shown includes a lubricating oil inlet 33 opened on the surface of the rotating shaft body 1 , an anti-falling wire 32 is installed on the surface of the lubricating oil inlet 33 , and a protective plug cover 31 is installed on the other side of the anti-falling wire 32 .

[0027] It should be noted that the sealing mechanism 3 includes a lubricating oil inlet 33 opened on the surface of the rotating shaft body 1, and an anti-falling wire 32 is installed on the surface of the lubricating oil inlet 33, and a protective plug cover 31 is installed on the other side of the anti-falling wire 32. When lubricating oil needs to be added, the protective plug cover 31 is opened first, and the lubricating oil will pass through the lubricating oil inlet 33 and enter the lubricating oil storage tank 6.

[0028] In the specific implementation process, Figure 5 The lubrication mechanism 5 shown includes a fixed block 51 installed inside the lubricating oil storage tank 6, a support plate 52 is installed on the top of the fixed block 51, and a baffle 53 is fixedly installed on one end of the support plate 52 away from the fixed block 51.

[0029] It should be noted that the lubricating mechanism 5 includes a fixed block 51 installed inside the lubricating oil storage tank 6, a support plate 52 is installed on the top of the fixed block 51, and a baffle 53 is fixedly installed on the end of the support plate 52 away from the fixed block 51. When the lubricating oil enters the lubricating oil storage tank 6, in order to prevent the lubricating oil from flowing back to the lubricating oil inlet port 33, the baffle 53 will play a blocking role to prevent the reflux of the lubricating oil from flowing out.

[0030] In the specific implementation process, Figure 2 As shown, an oil outlet hole 7 is opened on the left side of the rotating shaft body 1, and a ball 8 is installed in the oil outlet hole 7.

[0031] It should be noted that an oil outlet hole 7 is opened on the left side of the shaft body 1, and a ball 8 is installed in the oil outlet hole 7. When the lubricating oil reaches the ball 8, the shaft body 1 rotates, thereby driving the ball 8 to rotate together. At this time, the ball 8 will bring the lubricating oil out of the lubricating oil storage tank 6 under the action of rotation, thereby achieving an automatic lubrication effect.

[0032] In the specific implementation process, Figure 4 As shown, one side of the pull rope 4 is connected to the protective plug cover 31 , and the other side is connected to the surface of the baffle 53 .

[0033] It should be noted that one side of the pull rope 4 is connected to the protective plug cover 31, and the other side is connected to the surface of the baffle 53. When the protective plug cover 31 is opened, the pull rope 4 will open the baffle 53 connected thereto by pulling. At this time, the lubricating oil enters the gap between the baffle 53 and the lubricating oil storage tank 6 and reaches the position of the ball 8. When not in use, the protective plug cover 31 will fit tightly with the lubricating oil inlet port 33, the pull rope 4 connected thereto will return to its original appearance, and the baffle 53 will also block the passage of the lubricating oil storage tank 6 to prevent the lubricating oil from flowing out.

[0034] In the specific implementation process, Figure 2 The material used for the pull rope 4 shown is a high molecular weight polyethylene rope.

[0035] It should be noted that the material used for the pull rope 4 is a high molecular weight polyethylene rope.

[0036] In the specific implementation process, Figure 2 The material used for the rotating shaft body 1 is a polymer composite material.

[0037] It should be noted that the material used for the shaft body 1 is a polymer composite material.

[0038] The working principle of this embodiment is as follows: during specific use, when it is necessary to add lubricating oil, the protective plug cover 31 is opened first, and the lubricating oil will pass through the lubricating oil inlet port 33 and enter the lubricating oil storage tank 6. After the lubricating oil enters the lubricating oil storage tank 6, in order to prevent the lubricating oil from flowing back to the lubricating oil inlet port 33, the baffle 53 will play a blocking role to prevent the reflux of the lubricating oil from flowing out. When the lubricating oil reaches the ball 8, the shaft body 1 rotates, thereby driving the ball 8 to rotate together. At this time, the ball 8 will bring the lubricating oil out of the lubricating oil storage tank 6 under the action of rotation, thereby achieving an automatic lubrication effect. When the protective plug cover 31 is opened, the pull rope 4 will open the baffle 53 connected to it by pulling. At this time, the lubricating oil enters the gap between the baffle 53 and the lubricating oil storage tank 6 and reaches the position of the ball 8. When not in use, the protective plug cover 31 will fit tightly with the lubricating oil inlet port 33, the pull rope 4 connected to it will return to its original appearance, and the baffle 53 will also block the passage of the lubricating oil storage tank 6 to prevent the lubricating oil from flowing out.
