[0037] The working principle of this embodiment is as follows: when the inverter connection structure with quick assembly and disassembly for industrial automatic control instruments is put into use, the groove on the back of the wiring housing 2 is aligned with the fixing plate 3, and the clamping plate 401 is pressed to compress the spring 404 to slide on the inner wall of the limit block 403, so that the outer wall of the wiring housing 2 contacts the outer wall of the fixing plate 3, and the clamping plate 401 slides on the outer wall of the fixing plate 3 through the compression of the spring 404, so that the frequency modulator 1 is fixed to the fixing plate 3 through the gap between the outer wall of the wiring housing 2 and the clamping plate 401, and at the same time, the support plate 424 contacts the inner wall of the fixing plate 3 and is squeezed by the spring 425 to press the control rod 411 and the limit block 403.

[0039] The outer wall of the support rod 503 is fixedly connected to the inner wall of the limit block 3 504, the outer wall of the support rod 503 is slidably connected to the inner wall of the limit sleeve 506, the inner wall of the limit sleeve 506 is provided with a guide hole 507, the outer wall of the limit sleeve 506 is slidably connected to the hole wall of the guide hole 507, the outer wall of the support rod 503 is provided with a spring 4 505, one end of the spring 4 505 is fixedly connected to the inner wall of the limit sleeve 506, and the other end is fixedly connected to the outer wall of the limit block 3 504, and the outer wall of the limit sleeve 506 is provided with an assembly hole 508;

[0040] The limiting sleeve 506 is fixedly connected to the outer wall of the unlocking plate 509 at one end away from the support rod 503, a sliding hole 510 is provided at the top of the unlocking plate 509, the wall of the sliding hole 510 is slidably connected to the outer wall of the sliding rod 2 423, a limiting hole 2 511 is provided at the top of the unlocking plate 509, the wall of the limiting hole 2 511 is slidably connected to the outer wall of the limiting rod 512, a spring 513 is provided on the outer wall of the limiting rod 512, one end of the spring 513 is fixedly connected to the outer wall of the limiting rod 512, and the other end is fixedly connected to the wall of the limiting hole.

[0041] The working principle of this embodiment is as follows: after the frequency modulator 1 is installed in a suitable position, the support rod 503 is locked by adjusting the unlocking mechanism 6, and the support rod 503 is pressed against the limit block 3 504 by the spring 4 505 to slide on the inner wall of the limit sleeve 506, and is hinged with the support plate 2 501, driving the support plate 2 501 to contact the inner wall of the fixed plate 3, and generating pressure between the anti-slip sleeve 502 and the fixed plate 3, so that the frequency modulator 1 is fixed. When unlocking is required, the unlocking mechanism 6 is adjusted to contact the restriction on the support rod 503, and the support rod 503 is made to slide by pressing the adjustment mechanism. The rod 503 slides on the inner wall of the guide hole 507 through the limit block three 504 compressing the spring four 505, so that the hinge connection between the support plate two 501 and the support rod 503 is unlocked, and the unlocking plate 509 squeezes the limit rod 512 through the spring to make the unlocking plate 509 always in the position center of the locking mechanism 5, and after the unlocking plate 509 contacts the outer wall of the conical disk 427, it slides on the outer wall of the conical disk 427, driving the sliding rod two 423 to slide on the inner walls of the rotating block one 421 and the rotating block two 422, so that the support plate one 424 leaves the inner wall of the fixed plate 3 for quick release.

The positioning hole 602 opened on the outer wall of the center rod 601 has the same diameter as the guide hole 507 opened on the inner wall of the limiting sleeve 506, so that when the center rod 601 unlocks the locking mechanism 5, the center rod 601 is rotated to make the positioning hole 602 and the positioning hole 602 rotate with each other. The guide hole 507 corresponds to the guide hole 507, so that the support rod 503 can smoothly compress the spring four 505 to slide in the positioning hole 602, so that the support rod 503 is unlocked and the support plate two 501 is hingedly connected to the support plate one 424 to unlock the hinge connection, and at the same time, the control rod 411 is unlocked and the limit block one 403 is driven to slide on the inner wall of the wiring housing 2 by rotating with the rotating block one 421 and the rotating block two 422, so that the clamping plate 401 slides on the outer wall of the fixing plate 3 and leaves the fixing plate 3 for quick disassembly;

[0043] One end of the sleeve 603 close to the limiting sleeve 506 is fixedly connected to the outer wall of the limiting sleeve 506 , the outer wall of the sleeve 603 is slidably connected to the inner wall of the fixing sleeve 604 , and the outer wall of the fixing sleeve 604 is fixedly connected to the inner wall of the wiring housing 2 .
