By controlling the supporting end of the first support rod 160 to extend into the clamping grooves 171 with different heights, the opening angle of the door panel 120 can be adjusted. When the supporting end of the first support rod 160 extends into the lower clamping groove 171, the opening angle of the door panel 120 is smaller. When the supporting end of the first support rod 160 extends into the higher clamping groove 171, the opening angle of the door panel 120 is larger.

[0051] Further, the electric control box 100 includes two first support rods 160 and two first card slots 170. The two first support rods 160 are respectively arranged on both sides of the inner surface of the door panel 120, and the two first card slots 170 are respectively arranged on both sides of the surface of the housing 110 and are correspondingly arranged with the first support rods 160.

[0052] In this embodiment, the two first support rods 160 can respectively extend into the clamping grooves 171 of the corresponding first card slots 170, so that both sides of the door panel 120 are respectively supported by the corresponding first support rods 160 to improve the stability of the door panel 120 in the open state.

[0053] In some embodiments, the inner surface of the door panel 120 has a first limiting portion 121, and the first support rod 160 can be clamped with the first limiting portion 121, so that the first support rod 160 is limited to the inner surface of the door panel 120.

[0054] In this embodiment, when the door panel 120 is in the closed state, the first support rod 160 can be clamped with the first limiting portion 121, so that the first support rod 160 is limited to the inner surface of the door panel 120 to ensure that the door panel 120 can be smoothly closed. When the door panel 120 is in the open state, the first support rod 160 is removed from the first limiting portion 121, so that the first support rod 160 can extend into the clamping groove 171 of the first card slot 170 to support the door panel 120.

[0055] Figure 4 It is a schematic structural diagram of the second embodiment of the electric control box 100 of the present utility model; Figure 5 It is a partial structural schematic diagram of the second embodiment of the electric control box 100 of the present utility model; Figure 6 It is for the electric control box 100 of the present utility model Figure 5 The partial enlarged view at B. Some structures of the second embodiment are the same as those of the first embodiment. The following will describe the differences between the two, and the same parts will not be elaborated.

[0056] In the second embodiment of the present utility model, the electric control box 100 further includes a second support rod 180 and a second card slot 190. The second support rod 180 is in a square frame shape, and both ends of the second support rod 180 are movably arranged on the inner surface of the door panel 120. The second card slot 190 is arranged on the surface of the housing 110 and is correspondingly arranged with the first support rod 160.

[0057] The second card slot 190 includes a plurality of inclined slots 191 with different heights, and the second support rod 180 can extend into the inclined slots 191 with different heights to adjust the opening and closing degree of the door panel 120.

[0058] In this embodiment, the connecting end of the second support rod 180 is movably connected to the inner surface of the door panel 120, so that the support end at the other end can move freely. When the door panel 120 is opened, the support end of the second support rod 180 can be engaged with the corresponding inclined slot 191, so that the door panel 120 is supported and maintained at a certain opening and closing angle. By controlling the support end of the second support rod 180 to extend into the engaging slots 171 at different heights, the opening and closing angle of the door panel 120 can be adjusted. When the support end of the second support rod 180 is engaged with the lower inclined slot 191, the opening angle of the door panel 120 is smaller. When the support end of the second support rod 180 is engaged with the higher inclined slot 191, the opening angle of the door panel 120 is larger.

[0059] Further, the second support rod 180 includes a support portion 181 and a clamping portion 182. Both ends of the clamping portion 182 are respectively connected to a support portion 181. The support portion 181 is movably connected to the inner surface of the door panel 120. In the state where the door panel 120 is opened, the clamping portion 182 can extend into the inclined slot 191.

The extending direction of the support portion 181 is substantially perpendicular to the extending direction of the clamping portion 182. The support portion 181 can rotate relative to the door panel 120. By rotating the clamping portion 182 to different angles, the clamping portion 182 can be engaged with the inclined slots 191 at different heights, thereby adjusting the opening and closing angle of the door panel 120.

[0061] In some embodiments, the inner surface of the door panel 120 has a second limiting portion 122. The clamping portion 182 can be engaged with the second limiting portion 122, so that the second support rod 180 is limited to the inner surface of the door panel 120.

[0062] In this embodiment, when the door panel 120 needs to be changed from the opened state to the closed state, the support portion 181 of the second support rod 180 is engaged with the second limiting portion 122, so that the second support rod 180 is limited to the inner surface of the door panel 120, ensuring that the door panel 120 can be smoothly closed.

[0063] In some embodiments, the end of the door panel 120 away from the ground is rotatably connected to the housing 110.

[0064] If the end of the door panel 120 close to the ground is rotatably connected to the housing 110, when the door panel 120 is opened, the door panel 120 will rotate towards the side close to the ground. At this time, the door panel 120 will form an obstacle, which is not conducive to maintenance personnel to maintain the electrical equipment 140 located in the housing 110.

[0065] In this embodiment, one end of the door panel 120 far from the ground is rotatably connected to the housing 110, so that when the door panel 120 is in the open state, the door panel 120 can rotate away from the ground, providing sufficient space for maintenance personnel to ensure that the maintenance personnel can smoothly maintain the electrical equipment 140 located in the housing 110.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
