A delivery pipe 205 is fixedly and continuously connected to the lower ends of the outer walls on both sides of the oil reservoir 204. The other end of each delivery pipe 205 extends into the interior of the support block 206. Diverter pipes 208 are fixedly connected to both sides of the end of the delivery pipe 205 inside the support block 206. The end of each diverter pipe 208 away from the delivery pipe 205 extends to the outside of the support block 206, and the lower end of each diverter pipe 208 is inside the gear cover 201. A bearing component 207 is fixedly installed in the center of the bottom surface of the support block 206. Figure 3 As shown, the bottom opening of each shunt pipe 208 faces the outer side of the driven gear 103 or the driving gear 104.

[0028] An oil filling box 209 is fixedly connected to the inner center of the oil storage box 204. An opening 210 is provided in the center of the top surface of the oil filling box 209. A stop block 212 is slidably connected to the inner wall of the oil filling box 209. A spring 213 is fixedly connected to the center of the bottom surface of the stop block 212. The bottom of the spring 213 is fixedly connected to the inner wall of the oil filling box 209. Figure 4 As shown, the spring 213 pushes the stop 212 upward, and the outer surface of the stop 212 is fixed with a silicone layer to reduce the connection gap with the inner wall of the oil reservoir 204.

[0029] Both sides of the outer wall of the oil filling box 209 are provided with openings 211. Both openings 211 are located below the stop block 212, and the inside of the oil filling box 209 is connected to the oil storage box 204 through the openings 211.

[0030] The lubrication mechanism 2 includes a gear cover 201. Lower dust collectors 202 are fixedly installed on both sides of the bottom surface of the gear cover 201. Sealing layers 203 are fixedly connected to the lower ends of the inner walls of both lower dust collectors 202. The transmission mechanism 1 includes a steering sleeve 101.

[0031] The working principle of this utility model:

[0032] When lubrication of the driven gear 103 and the drive gear 104 is required, an external pipe is inserted into the opening 210. Then, the external pipe is pushed downwards towards the oil filling box 209. The stop block 212 is pushed down gradually to below the opening 211. Then, the external pipe outputs lubricating oil, which enters the oil storage box 204 through the opening 211. Then, it enters each branch pipe 208 through the delivery pipe 205. Finally, the lubricating oil falls through the bottom opening of the branch pipe to the top of the driven gear 103 and the drive gear 104, completing the lubrication operation. After the external pipe is pulled out of the opening 210, the spring 213 releases its elastic potential energy to push the stop block 212 upwards until the top surface of the stop block 212 abuts against the inner wall of the oil filling box 209. At this time, the opening 210 is completely blocked by the stop block 212.
