[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: an emergency stop device for a distribution box, comprising an electric box 1, a protective box 2 is fixedly connected to the upper side of the right end surface of the electric box 1, a control button 6 for controlling the power switch is arranged inside the protective box 2 on the right side of the electric box 1, and the control button 6 will not automatically reset after being squeezed. A professional electrician is required to open the box door and reclose the circuit breaker before power can be turned on; a power socket 7 is arranged on the lower side of the control button 6 on the right side of the electric box 1, a plug 8 is inserted into the right side of the power socket 7, and an emergency stop component for controlling the power-off protection of the rotating rod 3 is arranged inside the protective box 2;

[0021] like Figure 2 As shown, the emergency stop assembly includes a ratchet disk 4, the rear end face of the ratchet disk 4 is fixedly connected to a connecting shaft 9, the surface of the connecting shaft 9 is rotatably connected to one end of 10, the other end of 10 is rotatably connected to a hinged rod 11, the lower end face of the hinged rod 11 is fixedly connected to a slider 12, the interior of the protective box 2 is fixedly connected to a limit plate 13, and the slider 12 is slidably connected to the upper side of the limit plate 13.

[0022] The hinged rod 11 is located on the right side of the control button 6. A rotating rod 3 is fixedly connected to the middle of the front end surface of the ratchet disk 4. The rotating rod 3 is rotatably connected to the protective box 2. The inner upper side of the protective box 2 is rotatably connected to the limit block 5, and the limit block 5 is slidably connected to the surface of the ratchet disk 4.

[0023] A one-way sleeve 16 is fixedly connected to the surface of the plug 8, a matching block 15 is slidably connected to the surface of the one-way sleeve 16, a matching plate 14 is fixedly connected to the upper end surface of the matching block 15, and the upper end surface of the matching plate 14 is fixedly connected to the lower end surface of the slider 12.

[0024] Furthermore, when the emergency stop assembly is in power-off operation, the limit block 5 needs to be pushed away to facilitate the rotating rod 3 to drive the ratchet disc 4 to rotate counterclockwise.

[0025] Furthermore, the one-way sleeve 16 is made of rubber. When the hinged rod 11 moves to the left, the matching block 15 slides on the inclined portion of the one-way sleeve 16.
