[0016] like Figure 1-6As shown, this utility model provides a manual priority anti-misoperation padlock device, including an electrical control cabinet 1. The front of the electrical control cabinet 1 is fixedly provided with an operation hole 7. It also includes a padlock body 17. The front of the electrical control cabinet 1 is fixedly provided with a micro switch box 13, a pair of fixed plates 4, and fixed lock ears 2. A padlock movable plate 6 is slidably disposed within the pair of fixed plates 4. The padlock movable plate 6 has a through hole 5. A movable lock ear 3 is fixedly disposed at one end of the padlock movable plate 6, and a top rod 14 is fixedly disposed at the other end of the padlock movable plate 6. A movable lock hole 19 is disposed within the movable lock ear 3, and a fixed lock hole 18 is disposed within the fixed lock ear 2. An insertion hole 12 is disposed on one side wall of the micro switch box 13. Multiple sliding rods 15 are slidably disposed within the other side wall of the micro switch box 13. A pressure plate 22 is fixedly disposed at one end of each sliding rod 15. A spring 23 is sleeved on each sliding rod 15. The two ends of the spring 23 press against the pressure plate 22 and the inner wall of the micro switch box 13. A movable micro switch contact 21 is fixedly disposed on one side surface of the pressure plate 22. A fixed micro switch contact 20 is fixedly installed on the inner wall of the switch box 13; a vertical plate 8 is fixedly installed on the bottom surface of the padlock movable plate 6, a hook plate 10 is hinged to one side surface of the vertical plate 8, and a support plate 9 is fixedly installed on one side surface of the vertical plate 8, the top of the support plate 9 can contact the bottom surface of the hook plate 10; a limit post 11 is fixedly installed on the front of the electrical control cabinet 1, and the hook plate 10 can hook the limit post 11; a reinforcing plate 16 is fixedly installed at one end of multiple sliding rods 15; the micro switch box 13 is connected in series to the electric control circuit, and the movable micro switch... The movable switch contact 21 is electrically connected to the micro switch box 13, and the fixed micro switch contact 20 is electrically connected to the micro switch box 13. The movable micro switch contact 21 can contact the fixed micro switch contact 20. The movable lock lug 3 can contact the fixed lock lug 2. The lock beam of the padlock body 17 can pass through the movable lock hole 19 and the fixed lock hole 18 at the same time.

At this time, the insertion rod moves away from the pressure plate 22, and the pressure plate 22 moves to the right under the action of the spring 23. The rightward movement of the pressure plate 22 enables the movable micro switch contact 21 to contact the fixed micro switch contact 20, thereby connecting the electric circuit. The locking beam of the padlock body 17 passes through both the movable lock hole 19 and the fixed lock hole 18, locking the padlock body 17. At this time, the through hole 5 is away from the front of the operating hole 7, and the operating handle cannot crank in and out the circuit breaker.
