[0002] The connection between the motor box and the end cover needs to be sealed with a sealing structure, so that water and dust from the outside can enter the motor box and affect the normal operation of the motor. The traditional sealing structure is to manually apply glue on the mating surface of the motor box and the end cover. Sealing, this sealing method is troublesome and time-consuming to apply glue, and it is prone to leak coating, resulting in poor sealing, and the glue used for sealing is harmful to the human body. Working in this environment for a long time will cause certain harm to the health of the staff

The invention discloses a sealing structure for a motor box body and an end cover. The sealing structure comprises the motor box body and the end cover. A connecting end with a small inner diameter is arranged at the rear end of the end cover, the diameter of the connecting end is identical to the inner diameter of an opening formed in the motor box body, the connecting end is clamped in the opening of the box body, and the end, in contact of the end cover, of the opening of the motor box body is provided with a circle of chamfered groove. The root of the connecting end of the end cover is further sleeved with a sealing ring used for sealing the gap between the sealing box body and the end cover, the sealing ring is located in the chamfered groove formed in the opening of the motor box body, the motor box body is assembled with the end cover, the sealing ring is extruded and deformed through the chamfered groove, so that sealing is conducted in the radial direction and the axial direction at the same time, sealing is firm, and due to the fact that the sealing ring is used for replacing seal gum for sealing, assembling is convenient and fast, and toxin and pollution are avoided.
