Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3An emergency power supply box includes a box body 1. Four upper terminal blocks 2 are fixed at the top of the box body 1. A first quick-connect interface 3 is fixed on the upper terminal block 2. Four lower terminal blocks 4 are fixed at the bottom of the box body 1. A second quick-connect interface 5 is fixed on the lower terminal block 4. The second quick-connect interface 5 passes downward through the box body 1. Cables 6 are fixed on both the upper terminal blocks 2 and the lower terminal blocks 4. The cables 6 pass through the box body 1 and are located on the outside. An external operating handle knife switch 7 is fixed between the four upper terminal blocks 2 and the four lower terminal blocks 4. The handle end of the external operating handle knife switch 7 is located on the outside of the box body 1.

[0021] When this power transfer box is in operation and emergency power is needed, it can quickly connect to the generator vehicle and circuit system through the first quick-connect interface 3 and the second quick-connect interface 5 inside the box 1, enabling multiple users to access power supply in a timely, simultaneous / synchronous manner.

[0022] In actual use, it was found that when operating the external operating handle knife switch 7, the opening and closing status of the knife switch could not be observed when the cabinet door was closed. In order to solve the above problem, in this embodiment, the front end of the cabinet 1 is rotatably connected to the upper cabinet door 8 and the lower cabinet door 9. The upper cabinet door 8 and the lower cabinet door 9 are both connected to the cabinet 1 by hinges, and the lower cabinet door 9 is provided with a viewing window 10.
