[0019] As Figure 1-8 shown, the manual priority padlock device involved in the present utility model includes a padlock main board 1 fixed on the switch cabinet, an upper padlock board 2, a microswitch mounting bracket 5 fixed on the side of the switch cabinet, a microswitch 6, a manual operating shaft 7 and a return spring 8. The padlock main board 1 is provided with a main board hanging interface 11 and a manual unlocking hole 18. The padlock main board 1 vertically bends outward at the lower end of the main board hanging interface 11 to form a main board hanging part 12. The main board hanging part 12 is provided with a first lock hole 13. The upper padlock board 2 includes an upper padlock board driving part 15 placed on the back of the padlock main board 1 and arranged parallel to the padlock main board 1. The upper padlock board driving part 15 vertically bends to form an upper padlock board hanging part 16 that penetrates through the main board hanging interface 11 and is docked with the main board hanging part 12. The upper padlock board hanging part 16 is provided with a second lock hole 17 corresponding to the first lock hole 13. The upper padlock board driving part 15 is provided with an operating shaft lock hole 19 communicating with the manual unlocking hole 18. The microswitch mounting bracket 5 includes a mounting bracket fixing part 21 for fixing the microswitch 6. The mounting bracket fixing part 21 is sequentially bent to form a mounting bracket concave part 22. One end of the manual operating shaft 7 passes through the mounting bracket concave part 22 and is docked with the microswitch 6, and the other end passes through the mounting bracket concave part 22 and the operating shaft lock hole 19 in sequence and is then docked with the manual unlocking hole 18. The manual operating shaft 7 is provided with an operating shaft boss 23. The return spring 8 is sleeved on the manual operating shaft 7, one end of which abuts against the operating shaft boss 23, and the other end abuts against the mounting bracket concave part 22. The padlock has a manual priority function and can be unlocked manually, thus effectively preventing the misoperation of the grounding interlock mechanism, with more perfect functions and higher protection.

[0020] It further includes a driving pin 3 and a driving plate 10. The driving plate 10 includes a driving plate main body 26. Both ends of the driving plate main body 26 are bent to form driving plate blocking parts 27 for limiting the up and down movement of the upper padlock board driving part 15. The driving plate blocking parts 27 are provided with driving plate docking holes 28. The driving pin 3 is rotatably fixed in the driving plate docking holes 28. The upper padlock board driving part 15 is provided with a square transmission port 29 for limiting the movement of the driving pin 3. By swinging the driving plate 10, the upper padlock board 2 can be unlocked and moved, which is more convenient and fast in operation, more reliable in action, with better user experience and higher safety.

[0021] The driving pin 3 is provided with a driving pin docking portion 31 placed in the square transmission opening 29 and driving pin yielding grooves 32 provided at both ends of the driving pin docking portion 31, so that the swinging action is smoother and more stable, and the action is highly reliable.

[0022] It also includes a manual unlocking column 9, which includes an unlocking column pressing portion 34 for pressing the end of the manual operating shaft 7 and an unlocking column end stop portion 35 for pressing the limit. The manual operating shaft 7 is pressed by the manual unlocking column 9, and the manual action is safer and more reliable.

[0023] The padlock main board 1 is bent vertically outward at the upper end of the main board hanging interface 11 to form a main board storage portion 36. A main board receiving groove 37 for placing the manual unlocking column 9 is provided in the main board storage portion 36, which is more convenient to use.

[0024] Working process: Under normal conditions, the second lock hole 17 of the upper padlock plate 2 and the first lock hole 13 of the padlock main board 1 are fixed by a padlock. When manual priority access is required, the manual unlocking column 9 is pressed against the end of the manual operating shaft 7 from the manual unlocking hole 18 to make the manual operating shaft 7 move inward, and the manual operating shaft 7 is moved out of the operating shaft lock hole 19 of the upper padlock plate 2 to unlock the upper padlock plate 2. At the same time, the other end of the manual operating shaft 7 pushes the moving contact of the microswitch 6 to turn on the microswitch 6, and the microswitch 6 can control the controller of the electric interlocking mechanism of the switch cabinet, thereby realizing manual priority of the grounding interlocking mechanism of the switch cabinet. When the manual priority access is turned on, the controller of the electric interlocking mechanism no longer responds to the input command and cuts off the output, thereby effectively preventing the grounding interlocking mechanism from malfunctioning. At this time, the operator swings the driving plate 10 outward, so that the driving pin 3 drives the upper padlock plate 2 to move upward, thereby realizing manual unlocking of the upper padlock plate 2 and the padlock main board 1.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
