[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1 to 2 , an embodiment provided by the present utility model: a planetary reducer convenient for installation, including a base 1 and a motor housing 9. The base 1 serves as the foundation of the overall structure, supporting and fixing each component of the planetary reducer, and at the same time bearing the power output. The front side of the base 1 is fixedly connected with a shell 2, and the shell 2 provides external protection and mechanical support for the planetary reducer, ensuring the stable operation and safety of the internal components. The input shaft 3 is rotatably connected inside the base 1. The input shaft 3 is a structure for transmitting power, with a hollow design in the middle for the driving end of the internal rotating shaft of the motor housing 9 to be inserted. The rear side of the base 1 is fixedly connected with two sleeves 4. The sleeves 4 are key connection structures for connecting the motor housing 9 and the base 1. The outer part of the sleeve 4 is provided with a card slot 8. The design of the card slot 8 enables the internal structure of the motor housing 9 to be inserted to complete the snap fixation. The push rod 5 is slidably connected inside the sleeve 4. The push rod 5 is used to operate the internal structure of the sleeve 4 to complete the separation and disassembly. The front side of the push rod 5 is fixedly connected with a button 7. The design of the button 7 facilitates the construction personnel to control and operate the push rod 5. A first spring 6 is sleeved outside the push rod 5. The first spring 6 is a structure for resetting the push rod 5. By resetting it, the next installation is completed.

[0033] Referring to Figures 3 to 4, there are multiple clamping rods 10 slidably connected inside the motor housing 9. The clamping rods 10 are engaged with the card slots 8 of the sleeve 4 to complete the installation. A baffle 11 is fixedly connected to the outside of the clamping rod 10, and a second spring 12 is sleeved on the outside of the clamping rod 10. The reaction force of the second spring 12 is used to push the clamping rod 10 into the inside of the card slot 8. A planetary gear set 13 is fixedly connected to the front side of the input shaft 3. The planetary gear set 13 is composed of a rack ring and multiple gears inside, which is the key structure of the reducer. A rotating component for squeezing lubricating oil to lubricate the planetary gear set 13 is arranged inside the housing 2. An output shaft 14 is fixedly connected to the front side of the planetary gear set 13.

[0034] Refer to Figures 1 to 3 , the front sides of the two first springs 6 are respectively fixedly connected to the rear sides of the two buttons 7. One end of the first spring 6 is fixed to reset the button 7 and the push rod 5. The two buttons 7 are respectively slidably connected inside the base 1, and then drive the push rod 5 to operate the internal clamping rod 10. The outside of the two sleeves 4 is slidably connected inside the motor housing 9, and the outside of the multiple clamping rods 10 is slidably connected inside the card slots 8. The clamping and separation are realized through the sliding state of the clamping rod 10 and the card slot 8.

[0035] Refer to Figures 4 to 5 , the rotating component includes a fixing frame 15. The fixing frame 15 is composed of a U-shaped plate and has a space for rotation inside for squeezing operation. The left side of the fixing frame 15 is fixedly connected to the left side inside the housing 2. A rotating inclined plate 17 is rotatably connected inside the fixing frame 15. The structure at the rear side is squeezed by the rotation of one end of the rotating inclined plate 17. A lubricating oil bag 19 is fixedly connected inside the fixing frame 15. Lubricating oil for gear lubrication is arranged inside the lubricating oil bag 19, which can reduce gear wear. A nozzle 16 is fixedly connected inside the fixing frame 15. The internal lubricating oil is sprayed onto the planetary gear set 13 through the nozzle 16. A third spring 18 is fixedly connected to the left side of the rotating inclined plate 17. The left side of the third spring 18 is fixedly connected to the left inner wall of the housing 2. The third spring 18 is used to reset the rotating inclined plate 17 for multiple squeezing and spraying. An extrusion plate 20 is fixedly connected to the outside of the planetary gear set 13. Pressure is applied to the rotating inclined plate 17 through the regular rotation of the extrusion plate 20 for multiple squeezes. The rear side of the nozzle 16 is fixedly connected to the front side of the lubricating oil bag 19. The material of the lubricating oil bag 19 is plastic, and the plastic has good oil resistance and chemical corrosion resistance, which is suitable for the manufacture of the lubricating oil bag 19.

[0036] Working principle: First, the staff aligns the driving end of the input shaft 3 and the motor housing 9. By inserting two sleeves 4 into the interior of the motor housing 9, two clamping rods 10 are pushed up along the inclined plane and slide inside the motor housing 9. When the clamping rods 10 are aligned with the card slots 8, due to the reaction force of the second spring 12, the clamping rods 10 are pushed into the interior of the sleeves 4, completing the installation and fixation of the speed reducer and the motor housing 9. When disassembly is required, by pressing the button 7, the push rod 5 slides inside the sleeve 4, extruding the two clamping rods 10 to separate the clamping rods 10 from the sleeves 4, and then sliding the sleeves 4 out of the interior of the motor housing 9 to complete the disassembly. No complex professional tools or equipment are required, so installation time and labor costs can be saved and efficiency can be improved.

[0037] Secondly, the rotation of the motor housing 9 drives the input shaft 3 to rotate, thereby driving the planetary gear set 13 to rotate inside the outer housing 2. The rotation of the planetary gear set 13 drives the externally fixed extrusion plate 20 to rotate. When the bottom of the extrusion plate 20 rotates to the right side of the rotating inclined plate 17, the rotating inclined plate 17 is extruded to rotate inside the fixing frame 15, thereby squeezing the internal lubricating oil bag 19. The lubricating oil inside the lubricating oil bag 19 is sprayed onto the planetary gear set 13 through the nozzle 16. At the same time, due to the reaction force of the third spring 18, the rotating inclined plate 17 is pushed to complete the reset for the next extrusion and spraying, effectively reducing the direct contact between metal surfaces, thereby reducing friction and wear and extending the service life of the gears.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
