Problems solved by technology

[0006] The purpose of the present invention is to provide a padlock mechanism of an electric operating device for the poor supporting strength of the padlock mechanism of the existing circuit breaker electric operating mechanism, which can be pulled out to cause safety accidents when the electric operating mechanism is automatically controlled. Realize the padlock of the electric operating mechanism, which not only avoids the handle of the electric operating device being misoperated during maintenance, but also ensures that the padlock cannot be pulled out when the electric operating mechanism is automatically controlled

Embodiment

[0025] as attached Figure 1-5 As shown, the padlock mechanism of the electric operating device includes an operating handle 1, a padlock 2 and a state conversion dial 3. The handle 1 is mounted on the rotating shaft 4 and can rotate around the rotating shaft 4, and the rotating shaft 4 is mounted on the shell A of the electric operating device. superior. Wherein, the padlock 2 is installed on the installation shaft 5 and can rotate around the installation shaft 5, and the installation shaft 5 is installed on the shell A of the electric operation device.

[0026] During the counterclockwise rotation of the padlock 2, one end can be locked against the limit step 101a protruding from the turntable 101 of the handle 1 to lock it, and the padlock 2 can leave the limit step 101a during the clockwise rotation to unlock it; specifically , the limit step 101a is installed on the outer edge surface of the turntable 101, and the end of the padlock 2 corresponding to the limit step 101a...

Abstract

A padlock mechanism of an electrically operated device comprises an operation handle (1), a padlock (2) and a state switching toggle (3), the handle (1) is mounted on a rotating shaft (4) and can rotate around the rotating shaft (4), and the padlock mechanism is characterized in that the padlock is mounted on an installation shaft (5) and can rotate around the installation shaft (5), in the anticlockwise rotation process, one end of the padlock (2) can abut against a limiting step (101a) extended out of a rotating disk (101) of the handle (1) to lock the limiting step, and the padlock (2) canbe departed from the limiting step (101a) to unlock the limiting step in the clockwise rotation process. The padlock mechanism realizes padlock of the electrically operated device via rotation, the handle of the device is prevented from misoperation during maintenance, and it is ensured that the padlock cannot be pulled out during automatic control of the electric operation mechanism.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker electric operating devices, and in particular relates to a padlock mechanism of the electric operating device. Background technique [0002] Low-voltage circuit breaker, also known as automatic switch, is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse switch and The combination of overheating and underheating relays, etc., and generally does not need to change parts after breaking the fault current, has been widely used. [0003] The opening and closing actions of traditional miniature circuit br...
