The utility model aims to provide a structure for guaranteeing the sealing reliability of a motor so as to solve the problems in the prior art.

The technical scheme adopted for achieving the aim of the utility model is that the structure for guaranteeing the sealing reliability of the motor comprises an armature, an oil seal, a front end cover, a stator, a protecting belt, a rear end cover and a shell.

The shell is of a cylindrical structure, the stator is installed in the shell, the front end cover and the rear end cover are respectively fixed at two ends of the shell, and the protecting belt is sleeved at an opening of the shell.

The front end cover is provided with a threaded through hole and a mounting through hole for the power supply pivot to pass through, one end of the armature passes through the front end cover and the stator, and the oil seal is arranged between the armature and the front end cover.

In the detection state, the air compressor is communicated with the inside of the shell through the threaded through hole of the front end cover.

And in the detection completion state, the screw I is screwed into the threaded through hole of the front end cover and is sealed by adopting silica gel.

Further, the screw I is a hexagon socket head end set screw.

Further, the front end cover is fixed with the shell through a plurality of screws II.

Further, the rear end cover is fixed with the shell through a plurality of screws III.

The technical effect of the utility model is that the structure is provided with the threaded through hole for detecting the air tightness, compressed air can be introduced to detect the air tightness, after the air tightness is detected to be qualified, the threaded through hole is blocked, the situation of misjudgment in a factory test is avoided, and the motor performance is stable and meets the use requirement.
