DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 7 , a power distribution control device with an external power supply, comprising a distribution box housing 1 and a device mounting plate 2, wherein a maintenance mechanism 3 and a power supply mechanism 4 are provided on the surface of the distribution box housing 1;

[0023] The maintenance mechanism 3 enables operators to more easily perform maintenance operations on the equipment installation plate 2, and the power supply mechanism 4 is used to provide additional power guarantee for this distribution box.

[0024] The maintenance mechanism 3 includes four support frames 301, which are fixed to the inner wall of the distribution box casing 1. A slider 302 is slidably connected to the surface of the support frame 301, and the slider 302 is fixedly connected to the surface of the equipment mounting plate 2. Two fixed housings 303 are fixed on the left and right sides of the surface of the distribution box casing 1. A movable housing 304 is slidably connected to the inner wall of the fixed housing 303. A combination plate 305 is fixed to the surface of the movable housing 304. A fixing hole 306 is provided on the surface of the combination plate 305. Through holes 307 are provided on the surfaces of the fixed housing 303 and the movable housing 304. Bolts 308 penetrate the surface of the fixed housing 303. Fastening nuts 309 are threadedly connected to the surface of the bolts 308. A through slot is provided on the back of the distribution box casing 1. Two L-shaped plates 310 are fixed to the back of the distribution box casing 1. A baffle 312 is slidably connected to the surface of the L-shaped plate 310.

[0025] The fixing hole 306 is used to fix to the wall by screws. After the surface of the distribution box casing 1 is opened, the device mounting plate 2 can be pulled outward so that the device mounting plate 2 drives the slider 302 to slide forward on the surface of the support frame 301, so that the device mounting plate 2 can move forward inside the distribution box casing 1, so that the operator can more conveniently perform maintenance operations on the control components on the surface of the device mounting plate 2. At the same time, when it is necessary to inspect the rear side of the device mounted on the surface of the device mounting plate 2, the fastening nut 309 on the surface of the bolt 308 can be removed, and the bolt 308 can be removed from the through hole 307. After that, the entire distribution box casing 1 can be pulled forward so that the operator can enter the rear side of the distribution box casing 1, and then the baffle 312 can be pushed upward so that it can slide upward inside the L-shaped plate 310, thereby making the rear side of the distribution box casing 1 open, so that the operator can directly perform maintenance operations on the back side of the control components on the surface of the device mounting plate 2, thereby making it easier for the operator to find potential problems and enabling a more comprehensive inspection effect to be obtained inside the distribution box casing 1.

[0026] Furthermore, the power supply mechanism 4 includes a power supply box 401, a battery 402, an automatic power transfer switch 403 and an external power cord 404. The power supply box 401 is fixed to the surface of the distribution box housing 1, the battery 402 and the automatic power transfer switch 403 are both fixed to the inner wall of the power supply box 401, the automatic power transfer switch 403 is electrically connected to the battery 402, and the external power cord 404 is electrically connected to the automatic power transfer switch 403, and the external power cord 404 runs through the power supply box 401;

[0027] During operation, an external power cord 404 is used to provide external power to the control components on the surface of the equipment installation plate 2 to avoid the control components from not being able to operate normally due to insufficient power supply from the battery 402. At the same time, the automatic power transfer switch 403 is used to control the switching between the external power supply and the battery 402, so that the battery 402 is used to supply power when the external power supply is cut off, making the power supply of this distribution box more diverse, avoiding the situation where it cannot be used due to power outages, thereby improving the practicality of this distribution box.

[0028] Furthermore, side panels 317 are fixed on both sides of the inner wall of the distribution box housing 1, and a positioning block 316 is fixed on the surface of the lower slider 302. A knob 318 is threaded through the surface of the side panel 317, and a limiting hole is opened on the surface of the positioning block 316 to cooperate with the knob 318.

[0029] When the equipment mounting plate 2 is located inside the distribution box housing 1, rotating the knob 318 to make it enter the limiting hole on the surface of the positioning block 316 can limit the lower slider 302, thereby preventing the equipment mounting plate 2 from driving the slider 302 to move on the surface of the support frame 301.

[0030] Furthermore, guide plates 313 are fixed on both the upper and lower sides of the inner wall of the fixed housing 303, and a sliding groove for cooperating with the guide plates 313 is opened on the surface of the movable housing 304, and the guide plates 313 are slidably connected to the surface of the sliding groove;

[0031] When the movable housing 304 slides on the inner wall of the fixed housing 303 , the guide plate 313 will slide together on the surface of the slide groove, so that the movable housing 304 can obtain a guiding effect, thereby improving the stability during movement.

[0032] Furthermore, an extension plate 314 is fixed to the surface of the movable housing 304, and a U-shaped plate 315 is fixed to the surface of the fixed housing 303;

[0033] The movable housing 304 can drive the extension plate 314 to move, and the extension plate 314 can contact the U-shaped plate 315 , thereby preventing the movable housing 304 from being separated from the interior of the fixed housing 303 .

[0034] Furthermore, a support plate 311 is fixed to the bottom of the L-shaped plate 310;

[0035] The support plate 311 can limit the bottom position of the baffle 312 to prevent the baffle 312 from sliding downward from the inside of the L-shaped plate 310 due to gravity.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
