The present invention includes a housing 1, an annular noise reduction plate 2 is fixedly installed on the inner wall of the housing 1, a cover plate 3 is installed on one side of the housing 1, an annular card slot 19 is opened on one side of the housing 1 close to the cover plate 3, an annular rubber card strip 20 is fixedly installed on the side of the cover plate 3 close to the housing 1, and the annular rubber card strip 20 is located inside the annular card slot 19. Four connection seats 4 are uniformly and fixedly installed on the outer side of one end of the housing 1 close to the cover plate 3. Threaded connection sleeves 5 are fixedly installed on the sides of the four connection seats 4 away from the cover plate 3. A positioning collar 6 is fixedly installed through the inside of the cover plate 3. An adjustment connection assembly 7 is fixedly installed on the side of the cover plate 3 away from the housing 1, and the four threaded connection sleeves 5 are all connected to the adjustment connection assembly 7;

[0023] The adjusting connection assembly 7 includes an annular frame 8, and the annular frame 8 is fixedly installed on the side of the cover plate 3 away from the housing 1. Four I-shaped transmission gears 9 are arranged inside the annular frame 8. A connecting bolt 10 is fixedly installed on one side of the I-shaped transmission gear 9. Four positioning bearings 11 are evenly and fixedly installed through the cover plate 3. Four connecting bolts 10 respectively rotate through the interiors of the four positioning bearings 11. The end of the connecting bolt 10 away from the I-shaped transmission gear 9 movably penetrates through the connecting seat 4 and is threadedly installed inside the threaded connection sleeve 5. A transmission outer tooth ring 12 is meshed and connected between the four I-shaped transmission gears 9. A transmission inner tooth ring 13 is fixedly installed inside the transmission outer tooth ring 12. A driving gear 14 is meshed and connected to the middle of the inner top end of the transmission inner tooth ring 13. A driving shaft rod 15 is fixedly installed through the driving gear 14.

The other end of the driving shaft rod 15 movably penetrates and extends to the outside of the annular frame 8. A circular adjusting block 17 is fixedly installed at the end of the driving shaft rod 15 located outside the annular frame 8. A hexagonal adjusting groove 18 is formed on the side of the circular adjusting block 17 away from the driving shaft rod 15.

[0024] During use, through the interaction of the housing 1, the annular noise reduction plate 2, the connecting seat 4, the threaded connection sleeve 5, the cover plate 3 and the adjusting connection assembly 7, it can be ensured that during the use of the noise reduction motor housing, the end cover thereon can be quickly installed or disassembled, which is convenient for people to operate better, so as to achieve better practicality.

After the connecting bolts 10 are separated from the threaded connection sleeve 5, stop rotating the circular adjustment block 17, and then the cover plate 3 can be removed from one end of the housing 1. The cover plate 3 drives the annular rubber strip 20 to disengage from the annular groove 19, completing the disassembly between the cover plate 3 and the housing 1. When it is necessary to install the cover plate 3 at one end of the housing 1, place the cover plate 3 on one side of the housing 1, and make the annular rubber strip 20 stuck inside the annular groove 19. At the same time, insert the four connecting bolts 10 into the connecting seat 4 respectively, and make one end of the connecting bolt 10 contact the inside of one end of the threaded connection sleeve 5. Then rotate the circular adjustment block 17 in the reverse direction, so that the connecting bolts 10 rotate in the reverse direction. The connecting bolts 10 rotate in the reverse direction and are threadedly inserted into the threaded connection sleeve 5. After the connecting bolts 10 are completely connected to the threaded connection sleeve 5, stop rotating the circular adjustment block 17, completing the installation between the cover plate 3 and the housing 1. In this way, during the use of the noise-reducing motor housing, the end cover on it can be quickly installed or disassembled, facilitating better operation by people, and thus facilitating better practicality.
