A ventilation opening is formed in the center of the rear end surface of the protective housing 2, and a dust-proof net II 9 is fixedly installed at the front end of the ventilation opening. Among them, sliding grooves are respectively formed on the peripheral surfaces of the lower ends of the base 1.

[0027] Furthermore, screw rods 13 are respectively fixedly connected to the peripheral surfaces of the upper surface of the base 1, and the outer ends of the screw rods 13 are respectively arranged inside the sliding grooves at the lower ends of the protective housing 2. Among them, nuts I 14 are threadedly connected to the upper ends of the screw rods 13.

[0028] Furthermore, the clamping assembly is composed of a fixing plate 10, a fixing rod 11 and a clamping block 12. There are two fixing plates 10, which are respectively arranged corresponding to the front ends of the screw rods 13. A fixing rod 11 is fixedly connected to the inner side surface of the fixing plate 10. A clamping block 12 is pivotally connected to the outer end of the fixing rod 11. The upper end of the clamping block 12 is respectively arranged directly above the sliding groove. Among them, an opening is formed in the center of the front end of the clamping block 12, and the opening is respectively clamped on the outer ends of the screw rods 13, and the nut I 14 is rotated for fixation.

[0029] Furthermore, a heat dissipation fan 7 is arranged in the center of the connection box 3, and the center of the heat dissipation fan 7 is fixedly sleeved on the outer end of the rotating rod 6.

[0030] Furthermore, heat dissipation copper sheets 15 are respectively closely attached to both sides of the outer end surface of the deceleration motor body 5.

[0032] Working principle: First, the whole device is fixed at the required position through the bolts 4 on the base 1. The chute design on the base 1 facilitates the cooperation with the screw 13 at the bottom of the protective housing 2. By rotating the first nut 14, the protective housing 2 is firmly fixed on the base 1 to ensure the stability of the structure. The clamping assembly, through the combination of the fixing plate 10, the fixing rod 11 and the clamping block 12, further enhances the connection strength between the protective housing 2 and the base 1. The opening design on the clamping block 12 allows it to be clamped on the screw 13 and tightened by rotating the first nut 14, providing additional support and stability. The reduction motor body 5 is installed inside the protective housing 2 and transmits power through the rotating rod 6 at the output end. When the reduction motor starts to work, the rotating rod 6 will rotate accordingly, driving external equipment (such as a roller rack) to move. The heat dissipation slots and the first dust-proof net 8 on the surface of the protective housing 2 are designed to allow air circulation, effectively discharging the heat generated by the motor operation. At the same time, the first dust-proof net 8 can block dust from entering and keep the interior clean. The heat dissipation fan 7 inside the connection box 3 is directly fixed on the rotating rod 6 and automatically works as the rotating rod rotates, further enhancing the heat dissipation effect. The air blown by the fan is discharged through the ventilation opening at the rear end of the protective housing 2 and the second dust-proof net 9, forming an effective heat dissipation cycle. The outer surface of the reduction motor body 5 is closely attached with heat dissipation copper sheets 15. Utilizing the high thermal conductivity of copper, the heat generated by the motor is quickly conducted to the base 1 and the air. Through the fastening connection of the upper and lower layers of heat dissipation copper sheets 15, the limiting rods 16 and the second nut 17, the continuity and effectiveness of heat transfer are ensured. The protective housing 2 not only plays a role in protecting the reduction motor body 5 from external impacts and damages, but also prevents impurities such as dust and water from entering the motor interior through its sealing design, extending the service life of the motor. Dust-proof nets are provided at the heat dissipation slots, ventilation openings and the front end of the connection box 3, effectively blocking external impurities from entering and protecting the internal components from contamination.
