The fixed frame moves away from the reduction bracket to break away from the contact with the U-shaped plate and releases the limit on the U-shaped plate. The fixed frame prevents the noise reduction frame from loosening due to accidental touch, thereby ensuring that the reducer body can maintain its noise reduction performance during operation, thereby effectively reducing the noise caused by mechanical vibration and further creating a quieter working environment. The U-shaped plate is moved upward to reset the contact with the inner wall of the installation groove and complete the installation of the noise reduction frame.

[0015] (2) The planetary reducer with a noise reduction structure can only move slowly through the reduction hole through which the liquid inside the load-bearing frame can move slowly, causing the load-bearing plate and the load-bearing rod to move slowly. The slow movement of the load-bearing rod causes the stabilizing plate to move slowly. The slow movement can help the stabilizing plate to achieve higher positioning accuracy during the adjustment process, ensuring that the stabilizing plate and the noise reduction frame fit closely, thereby enhancing the stability of the overall structure. The stabilizing plate moves toward the direction close to the support rod to contact the inner wall of the noise reduction groove and assist in fixing the noise reduction frame. The stabilizing plate contacts the inner wall of the noise reduction groove, which can effectively enhance the overall stability of the noise reduction frame and prevent it from loosening due to vibration or external force during operation, thereby further maintaining its noise reduction effect.

[0016] (3) The planetary reducer with a noise reduction structure drives the limit rod to move in the direction close to the button through the limit plate. The limit rod moves to contact the inner wall of the protective groove and limit the button. The button cannot be pressed due to the limit rod. When the noise reduction frame is removed, the button cannot be pressed, thereby avoiding the risk of accidental startup and preventing potential injuries or equipment damage. In addition, during inspection or maintenance, the equipment is kept stationary, which can improve the efficiency and safety of maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing frame 11 prevents the noise reduction frame 3 from loosening due to accidental touch, which can ensure that the reducer body 2 can maintain its noise reduction performance during operation, thereby effectively reducing the noise caused by mechanical vibration.

[0021] A fixing spring 12 is provided between the fixing rod 9 and the fixing frame 11 , and the fixing spring 12 can drive the fixing frame 11 to reset. The bottom of the U-shaped plate 7 is set as an inclined surface, and the U-shaped plate 7 contacts the inner wall of the support hole 5 .

[0022] The U-shaped plate 7 is in contact with the fixed frame 11, and the U-shaped plate 7 is in contact with the inner wall of the installation groove 4. The side of the fixed frame 11 close to the U-shaped plate 7 is set as an inclined surface. The U-shaped plate 7 moves upward and resets to contact the inner wall of the installation groove 4 and completes the installation of the noise reduction frame 3. The noise reduction frame 3 with quick-release design can be easily disassembled for replacement or repair without the need to disassemble the reducer body 2 as a whole.

[0023] When the present embodiment is working: when the noise reduction frame 3 needs to be disassembled, the fixing frame 11 is first manually pulled in the direction away from the deceleration bracket 1, and the fixing frame 11 moves in the direction away from the deceleration bracket 1 to pull the fixing spring 12, and the fixing spring 12 is deformed and accumulates force due to the pulling of the fixing frame 11, and at the same time, the fixing frame 11 moves in the direction away from the deceleration bracket 1 to break away from the contact with the U-shaped plate 7 and release the limit of the U-shaped plate 7, and after the limit of the U-shaped plate 7 is released, the U-shaped plate 7 is manually pressed downward to move, and the U-shaped plate 7 moves to The support spring 8 is squeezed by the U-shaped plate 7 to produce deformation and accumulate force.

After the limit of the U-shaped plate 7 is released, the U-shaped plate 7 is manually pressed downward, and the U-shaped plate 7 moves downward to squeeze the supporting spring 8. The supporting spring 8 is squeezed by the U-shaped plate 7 to produce deformation and store force. At the same time, the noise reduction frame 3 is manually pushed to move in the direction close to the fixed plate 10 and contact with the reducer body. 2, the noise reduction frame 3 moves toward the direction close to the fixing plate 10 so that the mounting groove 4 is aligned with the U-shaped plate 7. After the mounting groove 4 is aligned with the U-shaped plate 7, the U-shaped plate 7 is released so that the U-shaped plate 7 moves upward and resets under the elastic force of the supporting spring 8. The U-shaped plate 7 moves upward and resets to contact the inner wall of the mounting groove 4 and completes the installation of the noise reduction frame 3. After the noise reduction frame 3 is firmly installed, the button 148 is manually pressed to drive the motor 32 to rotate. The rotation of the motor 32 drives the reducer body 2 to operate and reduce the speed of the motor 32.

[0025] A load-bearing spring 138 is arranged between the load-bearing frame 131 and the load-bearing plate 132, and the load-bearing spring 138 can drive the load-bearing plate 132 to reset. Liquid is arranged inside the load-bearing frame 131, and the stabilizing plate 135 contacts the inner wall of the noise reduction groove 31. There are two groups of load-bearing frames 131, load-bearing plates 132, linkage plates 133, load-bearing rods 134, stabilizing plates 135, stabilizing holes 136 and deceleration holes 137.

[0029] When the present embodiment is working, the U-shaped plate 7 moves downward to contact with the linkage plate 133 and squeeze the linkage plate 133. The linkage plate 133 is squeezed by the U-shaped plate 7 and moves in the direction away from the support rod 6. The linkage plate 133 moves in the direction away from the support rod 6 and drives the stabilizing plate 135 to move out of contact with the noise reduction groove 31, so as to facilitate the removal of the noise reduction frame 3. At the same time, the stabilizing plate 135 moves in the direction away from the support rod 6 and drives the load-bearing rod 134 to move. The load-bearing rod 134 moves and drives the load-bearing plate 132 to move. The load-bearing plate 132 moves to pull the load-bearing spring 138. The load-bearing spring 138 is pulled by the load-bearing plate 132 to produce deformation and accumulate force. At the same time, the load-bearing plate 132 moves to squeeze the liquid inside the load-bearing frame 131. The liquid inside the load-bearing plate 132 is squeezed and can only move slowly through the deceleration hole 137. The liquid inside the load-bearing frame 131 can only move slowly through the deceleration hole 137, so that the load-bearing plate 132 and the load-bearing rod 134 move slowly. The load-bearing rod 134 moves slowly, so that the stabilizing plate 135 moves slowly. When the U-shaped plate 7 moves upward and resets, the U-shaped plate 7 moves upward and breaks away from the contact with the linkage plate 133, so that the load-bearing plate 132 moves toward the direction close to the support rod 6 under the elastic force of the load-bearing spring 138.

[0030] The linkage plate 133 moves in a direction away from the support rod 6, driving the stabilizing plate 135 to move. The stabilizing plate 135 moves to contact with the square plate 144 and squeezes the square plate 144. The square plate 144 moves in a direction away from the support rod 6 due to the squeezing of the stabilizing plate 135. The square plate 144 moves in a direction away from the support rod 6, driving the detection rod 143 to move. The movement of the detection rod 143 drives the detection plate 142 to move. The movement of the detection plate 142 pulls the detection spring 145. The detection spring 145 is squeezed. The pulling on the detection plate 142 causes deformation and accumulates force. At the same time, the detection plate 142 moves in the direction away from the support rod 6, driving the wire rope to move. The movement of the wire rope causes the limit plate 146 to move toward the button 148 under the elastic force of spring No. 1. The limit plate 146 moves toward the button 148, driving the limit rod 147 to move. The limit rod 147 moves and contacts the inner wall of the protective groove 149 to limit the button 148.
