Technical Field

[0001] The utility model relates to the technical field of micro motor reduction boxes, in particular to a micro motor reduction box cover. Background Art

[0002] A micromotor reducer is a miniature precision reducer used with a micromotor. It is usually assembled with a micromotor to form a micro reducer motor. The multi-stage gear transmission in the reducer reduces the speed and increases the torque to meet the mechanical equipment's demand for low speed and high torque. It is widely used in mechanical equipment transmission. The structure of a micromotor reducer generally consists of an external shell, a cover plate, and an internal gear set. The reducer cover plays an important role as a component that closes the reducer shell.

[0003] However, after the micromotor reducer cover is actually installed and fixed on the micromotor reducer using bolts, the bolts used to fasten the cover are mostly directly exposed to the outside. When used for a long time, a large amount of dust is easily collected on the outside, and the bolts are easily corroded when exposed to water, making them difficult to disassemble later.
