Detailed Description

The present utility model will be described more fully hereinafter with reference to the accompanying examples.

Referring to fig. 1 and 2, a permanent magnet motor controller comprises a controller main body 1, wherein a flange 2 is fixedly arranged at the edge of the bottom of the controller main body 1, four sliding holes 3 are formed in the flange 2, and the sliding holes 3 are symmetrically and uniformly arranged relative to the controller main body 1. A base 4 is arranged below the controller main body 1, and bolt holes 5 for installation are formed in four corners of the base 4 in combination with fig. 3. Four sliding rods 6 are fixedly arranged on the base 4, the sliding rods 6 are in one-to-one correspondence with the sliding holes 3 and penetrate through the sliding holes 3, fixing caps 7 are arranged at the upper ends of the sliding rods 6, and springs 8 sleeved on the sliding rods 6 are arranged between the fixing caps 7 and the flange 2 and between the flange 2 and the base 4. Wherein the spring 8 on the upper side of the flange 2 is fixedly connected with the fixing cap 7, and the spring 8 on the lower side of the flange 2 is fixedly connected with the base 4.

Two guard plates 9 with C-shaped structures are fixedly arranged on the base 4, and the guard plates 9 cover the flange 2 so as to improve the stability of the controller main body 1.

Referring to fig. 4 and 5, the upper end of the sliding rod 6 is provided with a plurality of C-shaped clamping grooves 10, one end of each clamping groove 10 is communicated with the upper end of the sliding rod 6, the other end of each clamping groove 10 is not communicated with the upper end of the sliding rod 6, and a sliding block 11 which is in sliding fit with the clamping groove 10 is integrally formed in the fixing cap 7. The outside of the fixed cap 7 is fixedly provided with an anti-slip raised line 12 along the circumference thereof, and a round angle is formed on the anti-slip raised line 12.

The fixing cap 7 is sleeved on the upper end of the sliding rod 6, the sliding block 11 is aligned with the clamping groove 10, the fixing cap 7 is pressed downwards, after the sliding block 11 reaches the bottom of the clamping groove 10, the fixing cap 7 is transversely rotated, the sliding block 11 on the fixing cap 7 is enabled to rotate to the other end of the clamping groove 10, the sliding block 11 is embedded into the clamping groove 10 under the action of the elastic force of the spring 8, and finally the fixing cap 7 cannot transversely rotate again.
