Embodiment Construction
[0018] Such as Figure 1 to Figure 3 As shown, the present invention provides a single-phase magnetic holding operation mechanism, which includes an upper yoke 10, a lower yoke 8, a magnetic sleeve 1, a moving iron core assembly 2, a lower plastic end block 4 and a metal fixed pressure plate 3. A coil 7 is arranged between the upper yoke 10, the lower yoke 8, and the magnetic sleeve 1. The moving iron core assembly 2 includes a moving iron core 21 and a plastic cover 22 threaded on its lower part. The moving iron core 21 The middle passes through the operation pull rod 12, the opening spring 16 and the closing pressure spring 15. The photoelectric sensor element 13 is embedded in the lower plastic end block 4, and the signal line of the photoelectric sensor element passes through the metal fixing plate 3 and the lower plastic end block. The grooves between the end blocks 4 lead out, and the metal fixed pressure plate 3 is fixed and pressed to the installation plane by bolts 11...
