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.

[0023] See also Figure 1-Figure 6 As shown, an electric control box with a protective bracket comprises an electric control box body 1, on which a door panel 2 is provided; a protective bracket 3 is slidably provided on the door panel 2, on which an observation window 5 is provided, and a guide structure 4 is connected between the protective bracket 3 and the door panel 2; the guide structure 4 comprises two guide rods 401, on which two guide rods 401 are fixed, and the protective bracket 3 is slidably connected to the guide rods 401; the guide structure 4 further comprises an anti-slip block 403 and a tension spring 404, the top of the guide rod 401 is fixed with an anti-slip block 403, and the anti-slip block 403 A tension spring 404 is fixed to the bottom end of which a protective bracket 3 is fixed; when the control switch needs to be operated, the protective bracket 3 is pulled downward, the protective bracket 3 slides with the guide rod 401, and the protective bracket 3 drives the observation window 5 to move downward so that the observation window 5 is not in contact with the sealing plate 402. At this time, the protective bracket 3 drives the tension spring 404 to extend. When the operation is completed, the protective bracket 3 is released, the tension spring 404 contracts and drives the protective bracket 3 to reset, and the control switch is protected through the observation window 5, which effectively prevents accidental touching of the control switch and the display screen, causing damage and affecting the normal use of the electric control box, thereby improving stability.

[0024] As a technical optimization solution of the utility model, a sealing plate 402 is fixed on the door panel 2, and the sealing plate 402 is located above the protective bracket 3.
