[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3An embodiment of this utility model provides a visual reducer oil level observation window structure, including a support plate 1, a base 2 fixedly connected to the lower surface of the support plate 1, a pin housing 3 provided inside the support plate 1, the outer wall of the pin housing 3 being located inside the base 2, a threaded block 4 being threadedly connected inside the pin housing 3, a handle 5 being fixedly connected to the upper surface of the threaded block 4, a spring 6 being provided on the lower surface of the threaded block 4, the outer wall of the spring 6 being located inside the pin housing 3, a pressing assembly being provided on the lower surface of the spring 6, the pressing assembly being used to fix the reducer, the pressing assembly including a sliding block 7, the upper surface of the sliding block 7 being located at the bottom end of the spring 6, a top head 8 being fixed on the lower surface of the sliding block 7, and a ball 9 being slidably connected inside the pin housing 3;

[0027] Specifically, the rotating handle 5 is used to drive the threaded block 4 to rotate. When the threaded block 4 rotates, it can cause the bottom end of the spring 6 to compress on the upper surface of the sliding block 7. When the bottom end of the spring 6 compresses on the upper surface of the sliding block 7, it can cause the outer wall of the ball 9 to slide inside the pin housing 3, thereby achieving the effect of fixing the reducer and greatly saving maintenance time and labor costs.

[0028] Reference Figures 4-6 The left and right sides of the latch housing 3 are provided with sliding channels 10. The outer wall of the sphere 9 is slidably connected to the inside of the latch housing 3 through the sliding channels 10. The upper surface of the support plate 1 is fixedly connected to the protective housing 11. The upper surface of the protective housing 11 is fixedly connected to the hydraulic rod 12. The output end of the hydraulic rod 12 is fixedly connected to the fixing frame 13. The inside of the fixing frame 13 is slidably connected to the first support rod 14. The outer wall of the first support rod 14 is fixedly connected to the first connecting rod 15. The outer wall of the first connecting rod 15 is fixedly connected to the first baffle 16. The inside of the fixing frame 13 is provided with a rotating assembly, which includes a second support rod 17. The outer wall of the second support rod 17 is slidably connected to the inside of the fixing frame 13. The outer wall of the second support rod 17 is fixedly connected to the second connecting rod 18. The outer wall of the second connecting rod 18 is fixedly connected to the second baffle 19. The outer wall of the first connecting rod 15 is rotatably connected to the inside of the second connecting rod 18.

[0029] Specifically, the output end of the hydraulic rod 12 is used to drive the fixed frame 13 to slide. When the fixed frame 13 slides, it can drive the outer wall of the first support rod 14 to rotate the first connecting rod 15. When the outer wall of the first support rod 14 drives the first connecting rod 15 to rotate, it can drive the outer wall of the first connecting rod 15 to rotate the outer wall of the first baffle 16. When the fixed frame 13 rotates, it can also drive the outer wall of the second support rod 17 to rotate the outer wall of the second connecting rod 18. The outer wall of the second connecting rod 18 is used to drive the second baffle 19 to rotate. This can achieve the opening and closing effect of the reducer housing, allowing for a direct view of the oil level inside the reducer and ensuring normal lubrication of the reducer.

[0030] Reference Figures 2-4 An input shaft 20 is rotatably connected inside the protective housing 11. A first gear 21 is fixedly connected to the outer wall of the input shaft 20. A second gear 22 is meshed with the tooth end of the first gear 21. A third gear 23 is fixedly connected to the outer wall of the second gear 22. The outer wall of the second gear 22 is rotatably connected inside the protective housing 11. A transmission gear 24 is meshed with the tooth end of the third gear 23. An output shaft 25 is fixedly connected inside the transmission gear 24. The outer wall of the output shaft 25 is rotatably connected inside the protective housing 11. The lower surface of the fixing bracket 13 is slidably connected to the outer wall of the protective housing 11. The outer wall of the first connecting rod 15 is rotatably connected to the inside of the protective housing 11. The outer wall of the second connecting rod 18 is rotatably connected to the inside of the protective housing 11.

[0031] Specifically, when the input shaft 20 rotates, it drives the first gear 21 to rotate. When the first gear 21 rotates, it can cause the outer wall of the second gear 22 to rotate at the tooth tip of the third gear 23. When the outer wall of the second gear 22 rotates at the tooth tip of the third gear 23, it can drive the interior of the transmission gear 24 to drive the outer wall of the output shaft 25 to rotate, thereby achieving the effect of the speed reducer rotating.

[0032] Working principle: When the device is needed, rotating the handle 5 drives the threaded block 4 to rotate. As the outer wall of the threaded block 4 rotates inside the pin housing 3, its lower surface compresses the top of the spring 6. As the bottom end of the spring 6 compresses the upper surface of the sliding block 7, the outer wall of the sliding block 7 slides inside the pin housing 3. When the outer wall of the sliding block 7 presses against the outer wall of the ball 9, the outer wall of the ball 9 slides inside the pin housing 3, ultimately fixing the reducer. The output end of the hydraulic rod 12 drives the fixing frame 13 to slide. The fixing frame 13 drives the first support rod 14 to slide. The outer wall of the first support rod 14 drives the outer wall of the first connecting rod 15 to rotate, which in turn drives the outer wall of the first baffle 16 to rotate. The fixing frame 13 drives the second support rod 14 to rotate. When the support rod 17 slides, the outer wall of the second connecting rod 18 rotates, causing the outer wall of the second connecting rod 18 to rotate, which in turn causes the outer wall of the second baffle 19 to rotate, ultimately achieving the opening and closing effect of the reducer housing. By rotating the input shaft 20, the first gear 21 rotates. When the teeth of the first gear 21 rotate, the outer wall of the second gear 22 rotates, causing the third gear 23 to rotate. When the teeth of the third gear 23 rotate, the internal part of the transmission gear 24 rotates, causing the output shaft 25 to rotate, ultimately achieving the rotation effect of the reducer. This not only eliminates the need to disassemble a large number of bolts as in traditional reducers, greatly saving maintenance time and labor costs, but also allows for a direct view of the oil level inside the reducer, enabling timely detection of abnormal oil levels and ensuring normal lubrication of the reducer.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
