Detailed ways

The utility model will be clearly and completely described below in conjunction with the embodiments.

Referring to accompanying drawings 1 and 2, a permanent magnet motor controller includes a controller main body 1, a flange 2 is fixedly arranged on the bottom edge of the controller main body 1, and four sliding holes 3 are opened on the flange 2 , the sliding holes 3 are arranged symmetrically and evenly with respect to the controller body 1 . A base 4 is provided below the controller main body 1, and with reference to the accompanying drawing 3, bolt holes 5 for installation are provided at the four corners of the base 4. Four sliding rods 6 are fixedly arranged on the base 4, and the sliding rods 6 correspond to the sliding holes 3 one by one and are inserted in the sliding holes 3. The upper ends of the sliding rods 6 are provided with a fixed cap 7, and the fixed cap 7 Between the flange 2 and between the flange 2 and the base 4 are provided springs 8 sleeved on the sliding rod 6 . The spring 8 on the upper side of the flange 2 is fixedly connected to the fixed cap 7 , and the spring 8 on the lower side of the flange 2 is fixedly connected to the base 4 .

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

In conjunction with accompanying drawing 4 and accompanying drawing 5, the upper end of sliding bar 6 is provided with the draw-in slot 10 of several C-shaped structures, and one end of draw-in slot 10 communicates with the upper end of slide bar 6, and the other end of draw-in slot 10 and slide bar The upper end of 6 is not connected, and a sliding block 11 that slides and fits with the card slot 10 is integrally formed in the fixed cap 7 . The outer side of the fixed cap 7 is fixedly provided with an anti-slip convex line 12 along its circumferential direction, and the anti-slip convex line 12 is formed with rounded corners.

Connect the fixed cap 7 to the upper end of the sliding rod 6, align the slider 11 with the card slot 10 and press the fixed cap 7 downward. After the slider 11 reaches the bottom of the card slot 10, rotate the fixed cap 7 horizontally to fix the The slider 11 on the cap 7 rotates to the other end of the slot 10, and is inserted into the slot 10 under the elastic force of the spring 8, finally making the fixed cap 7 unable to rotate laterally. And in this embodiment, the length of the connection of the two sections of springs 8 is greater than the length of the sliding rod 6, so after the fixing cap 7 is installed, the two sections of springs 8 are all in a compressed state, which can reduce the 1.
