A padlock hole is arranged at one end of the padlock member, a locking hole matched with the padlock hole is arranged on the shell, a locking block matched with the hand-automatic switching push block is arranged on one side of the padlock member, a limit block matched with the locking block is arranged on the hand-automatic switching push block, and when the hand-automatic switching push block is toggled to the electric position, the locking block moves with the padlock member and contacts the limit block, and constitutes a limit match between the padlock member and the hand-automatic switching push block.

[0005] The beneficial effects of the above structure are: the padlock assembly has a simple structural design, low cost, simple operation, and can realize reliable locking of the electric operating mechanism. During operation, the operator pulls out the padlock, hangs the padlock in the padlock hole of the padlock, the padlock is locked in the locking position, and the padlock stretches the tension spring, the first micro switch loses the restriction of the padlock, the second micro switch cuts off the power supply of the motor of the electric operating mechanism, the electric operation function of the electric operating mechanism is locked, and the locking block of the padlock contacts the limit block of the manual automatic switching push block, and the padlock pushes the manual automatic switching push block to the electric position, thereby realizing the manual operation function locking of the electric operating mechanism. The padlock locks the manual automatic switching push block through the locking block, and the structural design is simple, and the padlock can reliably lock the manual automatic switching push block. Therefore, the padlock assembly of the electric operating mechanism has the advantages of simple structure, stable and reliable performance, convenient assembly, safety and reliability, and low cost.

[0006] In particular, the padlock is provided with a shift block that matches the first micro switch, and the shift block moves with the padlock and triggers the first micro switch, and realizes the connection or disconnection of the first micro switch. The padlock triggers the first micro switch through the shift block, thereby ensuring that the padlock can reliably trigger the first micro switch, which is conducive to improving the working reliability of the padlock assembly.

The padlock is slidably arranged in the sliding groove of the bracket through the guide convex strips, thereby ensuring that the padlock can slide reliably on the bracket, and facilitating the assembly of the bracket and the padlock, and the assembly efficiency is higher.

[0008] In particular, two positioning posts are arranged on the bracket corresponding to the first micro switch, the two positioning posts are inserted into the positioning hole of the first micro switch, a hook is arranged on the bracket corresponding to one side of the first micro switch, the hook is engaged with the first micro switch, and the first micro switch and the hook are engaged. The first micro switch and the bracket are assembled in an engaging manner, which is conducive to improving the assembly efficiency of the padlock assembly.

[0009] In particular, the manual-automatic switching push block is provided with a toggle block that cooperates with the shell, and the toggle block is slidably arranged in the sliding hole of the shell. One end of the manual-automatic switching push block has a shielding part that cooperates with the manual operating shaft. When the manual-automatic switching is switched to the electric position, the shielding part moves with the manual-automatic switching push block and blocks the manual operating shaft. The other end of the manual-automatic switching push block has a triggering part that cooperates with the second microswitch. The triggering part moves with the manual-automatic switching push block and triggers the second microswitch, and realizes the connection or disconnection of the second microswitch. The toggle block of the manual-automatic switching push block is slidingly arranged on the shell. The user pushes the toggle block, and the toggle block drives the manual-automatic switching push block to slide, so as to ensure that the manual-automatic switching push block can slide reliably in the shell. When the manual-automatic switching push block is toggled to the manual operation position, the triggering part of the manual-automatic switching push block triggers the second microswitch, and the second microswitch cuts off the power supply of the motor of the electric operating mechanism, and the electric operation function is turned off. The user can operate the manual operating shaft, thereby realizing the manual operation function of the electric operating mechanism; when the manual-automatic switching push block slides to the electric operation position, the second microswitch loses the restriction of the triggering part, and the second microswitch turns on the power supply of the motor, and the blocking part of the manual-automatic switching push block blocks the manual operation shaft, and the user cannot operate the manual operation shaft, thereby realizing the electric operation function of the electric operating mechanism.
