[0025] Specifically, a cylinder 2 is fixedly installed above the reducer body 1, an oil filling box 5 and an arc-shaped bottom plate 4 are fixedly welded on the fixed end of the cylinder 2, and the telescopic end of the cylinder 2 is slidably connected in the bottom plate 4, and a guide tube 401 connected to the inside of the reducer body 1 is fixedly provided at the bottom of the bottom plate 4, so that the lubricating oil in the oil filling box 5 can drip into the reducer body 1 through the guide tube 401 to achieve a lubricating effect, and the diameter of the telescopic end of the cylinder 2 is equal to the diameter of the inner cavity of the bottom plate 4, so that the telescopic end of the cylinder 2 can close the guide tubes 401 one by one when extending, and can open the guide tubes 401 one by one when contracting, and a piston 3 and a sealing rubber ring 301 are fixedly provided on the telescopic end of the cylinder 2, so that the sealing rubber ring 301 can slide in the bottom plate 4. The sediment at the guide tube 401 is pushed away to avoid blockage, and the lubricating oil can be squeezed from the guide tube 401 into the reducer body 1, realizing a drip-type oil injection method to avoid waste of lubricating oil. A steering ring 501 and a fixed block 502 are fixedly provided on the upper surface of the oil injection box 5. A wire 6 is fixedly provided in the steering ring 501, and the wire 6 extends into the inside of the oil injection box 5 so that the wire 6 will not move at the turning point, and the wire 6 is fixedly connected to the fixed block 502 so that the fixed block 502 fixes the wire 6 on the upper surface of the oil injection box 5.

The float switch 8 is fixed with a travel switch 601, and the travel switch 601 is connected to the wire 6, and a button 602 is provided on the travel switch 601. When the button 602 is pressed, the travel switch 601 transmits a signal to the wire 6, and the wire 6 brings the signal to the signal converter 9 on the upper surface of the oil filling tank 5. The signal converter 9 processes the signal and transmits the signal to the pressure pump 10, and then the pressure pump 10 starts, thereby sucking the lubricating oil in the oil storage tank 11 into the oil filling tank 5. A rotating rod 801 is fixedly provided in the float switch 8, and a trigger rod 802 is rotatably provided on the rotating rod 801. A slide groove 803 is provided in 8, and a magnet 804 is slidably provided in the slide groove 803, and a small iron sheet is provided in the upper part of the slide groove 803. When the float switch 8 is in a vertical state, due to the gravity of the magnet 804, the magnet 804 will break away from the iron sheet in the upper part of the slide groove 803 and fall to the bottom of the slide groove 803, thereby colliding with the trigger rod 802, causing the trigger rod 802 to rotate along the rotating rod 801, and then pressing the button 602 to start the travel switch 601. When the lubricating oil in the oil filling tank 5 becomes more and more, the float switch 8 will gradually become horizontal and float on the surface of the lubricating oil, and the magnet 804 will slide in the slide groove 803, gradually approaching the iron sheet at the top of the slide groove 803. When it reaches a certain distance, the iron sheet will absorb the magnet 804.Thus, the reset spring at the bottom of the button 602 resets the button 602, closing the travel switch 601. The capacity of the oil storage tank 11 is much larger than the capacity of the oil filling tank 5, so that the user can store a large amount of lubricating oil in the oil storage tank 11, and there is no need to pay attention to the amount of lubricating oil frequently in the future, and the device can realize automatic oil filling.

[0026] The working principle and use process of the utility model are as follows: first, a large amount of lubricating oil is stored in the oil storage tank 11. When there is lubricating oil in the oil filling tank 5, the cylinder 2 can be started to extend and retract the telescopic end of the cylinder 2, so that the lubricating oil drips into the reducer body 1 through the guide tube 401 to achieve the lubrication effect. When the lubricating oil in the oil filling tank 5 gradually decreases, the float switch 8 will gradually drop, and finally be in a vertical state due to the action of gravity. Then the magnet 804 will separate from the iron sheet at the top of the slide groove 803 and fall to the bottom of the slide groove 803, thereby colliding with the trigger rod 802, causing the trigger rod 802 to rotate a certain angle along the rotating rod 801, and then pressing the button 602 to start the travel switch. The switch 601 transmits a signal to the signal converter 9, and the signal converter 9 transmits the processed signal to the pressure pump 10, thereby starting the pressure pump 10 and sucking the lubricating oil in the oil storage tank 11 into the oil filling tank 5. When the lubricating oil in the oil filling tank 5 reaches the horizontal position of the water level block 7, the float switch 8 will float horizontally on the surface of the lubricating oil, and the iron sheet in the slide groove 803 will attract the magnet 804, so that the magnet 804 is away from the trigger rod 802. Finally, the reset spring at the bottom of the button 602 will reset the button 602, thereby closing the travel switch 601, and then closing the pressure pump 10, achieving the purpose of automatic oil filling, so that the user does not need to pay attention to the amount of lubricating oil frequently.
