[0030] The lateral adjustment base 1 is locked on the longitudinal adjustment base 3 through a pitch angle locking assembly, and the roll angle adjustment slider 2 is locked on the longitudinal adjustment base 3 through a roll angle locking assembly.
[0031] The utility model respectively arranges a first arc groove 4 and a second arc groove 5 on the longitudinal adjustment base 3 and the transverse adjustment base 1, and the second arc grooves 5 on the transverse adjustment bases 1 on both sides are located on the same circle, the arc-shaped bottom of the transverse adjustment base 1 is slidably connected to the first arc groove 4, the arc-shaped bottom of the roll angle adjustment slider 2 is connected to the second arc groove 5, and the roll angle adjustment slider 2 is connected to the shell of the explosion-proof motor, thereby realizing the adjustment of the pitch angle and roll angle of the explosion-proof motor, and the transverse adjustment base 1 and the longitudinal adjustment base 3 and the roll angle adjustment slider 2 and the transverse adjustment base 1 are all in surface sliding contact, thereby realizing the horizontal adjustment while providing long-term and stable support for the explosion-proof motor.
[0032] Among them, the pitch angle locking assembly includes a plurality of pitch angle locking pins 6, and the sides of the longitudinal adjustment base 3 and the lateral adjustment base 1 are provided with a plurality of first pin holes 7, and the plurality of first pin holes 7 are distributed on a circle having the same center as the wall of the first arc-shaped groove 4, that is, the longitudinal adjustment base 3 and the lateral adjustment base 1 are locked by the pitch angle locking pins 6, and the pitch angle adjustment accuracy and adjustment range are respectively determined by the central angles corresponding to adjacent first pin holes 7 and the number of first pin holes 7.
