A fixed cover plate 212 is fixedly connected to the rear side of the top of the liquid storage tank 211. A rectangular slot 213 is opened on the lower right side of the fixed cover plate 212. A convex groove 214 is opened on the left and right sides of the top of the liquid storage tank 211. An installation groove 215 is opened on the left and right sides of the front of the liquid storage tank 211. A circular through hole 2 extending to the bottom is opened on the left and right sides of the top of the fixed cover plate 212. 16. Connecting grooves 217 are provided on both the left and right sides of the bottom of the inner wall of the liquid storage tank 211. Multiple liquid outlet holes 218 in a front-to-back array are provided on the bottom of the inner wall of the connecting groove 217. A circular through hole 219 extending to the outside is provided on the bottom of the inner wall of the liquid storage tank 211 corresponding to the circular through hole 16. A fixing ring 210 is fixedly connected to the inner wall of the left liquid outlet hole 218. A liquid outlet pipe 2101 is fixedly connected to the bottom of the fixing ring 210. The movable component 22 includes a movable rod 221. A rectangular groove is provided at the bottom of the movable rod 221. Rollers 222 are rotatably connected to the left and right sides of the inner wall of the rectangular groove. The outer wall of the rollers 222 is movably connected to the outer wall of the cam 14.

A limit plate 228 is fixedly connected to the top of the fixing rod 226.

[0032] In use, this utility model works as follows: the rotation of gear 3 19 drives the rotation of fixed rod 1 18, which in turn drives gear 2 17 to mesh with gear 1 15. At this time, rotating rod 13 rotates accordingly, which in turn drives cam 14 to rotate. When the outer wall of cam 14 contacts the outer wall of roller 222, it pushes roller 222 upward. Roller 222 drives movable rod 221 to move within the inner walls of circular through hole 16 and circular through hole 3 219. Simultaneously, movable rod 221 drives connecting plate 1 223 and fixed plate 224 to move. The movement of movable rod 221 causes fixed rod 226 to slide within the inner wall of circular through hole 2 216. At this time, spring 1 227 contracts under pressure. The fixed plate 224 moves, causing the movable baffle 225 to move within the inner wall of the connecting groove 217, thus opening the outlet hole 218. At this time, the lubricating oil inside the storage tank 211 flows out through the outlet hole 218 and the outlet pipe 2101 to lubricate gears 19, 15, and 17. When the outer wall of the cam 14 protrudes from the outer wall of the roller 222, the spring 227 releases its elastic force, pushing the movable rod 221 to reset the fixed rod 226. At this time, the movable baffle 225 descends into the connecting groove 217 to seal the outlet hole 218, preventing the lubricating oil from continuing to flow out. The structure is simple and easy to operate, and it can automatically lubricate the transmission gears, improving work efficiency.

[0033] Please see Figure 6 The cover structure 3 includes a movable cover plate 31. A rectangular insert 32 is fixedly connected to the lower left side of the movable cover plate 31. The outer wall of the rectangular insert 32 is movably connected to the inner wall of the rectangular slot 213. A convex plate 33 is fixedly connected to the front and rear sides of the bottom of the movable cover plate 31. The outer wall of the convex plate 33 is movably connected to the inner wall of the convex groove 214. A sleeve 34 is fixedly connected to the front and rear sides of the right side of the movable cover plate 31. An anti-slip push plate 35 is fixedly connected to the top of the movable cover plate 31. A rod 36 is movably connected to the inner wall of the sleeve 34. A connecting plate 37 is fixedly connected to the bottom of the two rods 36. A pressure plate 38 is fixedly connected to the right side of the connecting plate 37. A sliding sleeve 39 is fixedly connected to the front and rear sides of the left side of the connecting plate 37. A sliding rod 30 is movably connected to the inner wall of the sliding sleeve 39. A spring 301 is fitted under the outer wall of the sliding rod 30. The upper and lower ends of the sliding rod 30 are fixedly connected to the inner wall of the mounting groove 215.

[0034] In use, this utility model works as follows: By pressing down the lower pressure plate 38, the lower pressure plate 38 moves the connecting plate 37. The movement of the connecting plate 37 causes the insertion rod 36 to disengage from the inner wall of the insertion sleeve 34, and causes the sliding sleeve 39 to slide on the outer wall of the sliding rod 30, thereby compressing the spring 301. At this time, by pushing the anti-slip push plate 35 on the top of the movable cover plate 31, the movable cover plate 31 moves. The movement of the movable cover plate 31 causes the convex plate 33 to slide on the inner wall of the convex groove 214, and causes the rectangular insertion block 32 to disengage from the inner wall of the rectangular slot 213. This moves the convex plate 33 out of the inner wall of the convex groove 214, opening the top of the liquid storage tank 211 for easy inspection and replenishment of lubricating oil. After the lubricating oil is added, the lower pressure plate 38 is pressed down again, pushing the convex plate 33 into the convex groove 214, so that the rectangular insert 32 is inserted into the inner wall of the rectangular slot 213. The lower pressure plate 38 is released, and the sliding sleeve 39 is pushed by the second spring 301, causing the sliding sleeve 39 to move the second connecting plate 37, inserting the insert rod 36 into the insert sleeve 34 for sealing. The operation is simple and improves the maintenance convenience of the gear transmission device.
