With the continuous advancement of lighting technology and the growing demand for intelligent lighting, the variety and number of electrical components integrated into distribution cabinets have increased significantly, including but not limited to rectifiers, controllers, protectors, sensors, and communication modules. However, this development trend also brings many challenges, particularly in the design, installation, operation, and maintenance of distribution cabinets.

[0003] First, the electrical components in traditional DC lighting distribution cabinets are often fixed in place, making their position difficult to adjust once installed. This design not only limits the flexibility of the distribution cabinet but can also necessitate complete cabinet replacement for subsequent expansion or upgrades, increasing costs and time.

Positioning slots 216 are provided on the left and right sides of the inner cavity of the body 111. The positioning rod 215 is movably inserted in the positioning slot 216, and the end of the positioning rod 215 extending into the positioning slot 216 is fixedly connected to a magnetic plate 217;

[0060] The anti-static assembly 22 includes an assembly frame 221 that is slidably connected to the inner cavity of the landing gear 214. The tops of the left and right ends of the assembly frame 221 are threadedly connected to fastening bolts 222.

A conductive block 224 is fixedly connected to the inner ring of the landing gear 214. The conductive strip 223 and the conductive block 224 are electrically connected. A conductive slot 225 is defined on the front of the limiting rod 211 located at the right rear side of the body 111.

[0062] The top and bottom surfaces of the fastening bolt 222 are both provided with anti-skid pads, and the bottoms of the anti-skid pads are in contact with and connected to the top surface of the landing gear 214 .

[0063] It should be noted that the front of the blocking bar 232 is flush with the front of the assembly rack 221, so that the blocking bar 232 can prevent the accessories from falling and can also be installed on the assembly rack 221 by moving the blocking bar 232;

[0064] The interior of the positioning groove 216 is also provided with a magnetic element adapted to the magnetic attraction plate 217 , so as to enable the magnetic attraction plate 217 to be stably adsorbed in the positioning groove 216 ;

[0065] A metal protrusion is provided on the top of the assembly frame 221 , and the protrusion is in contact with the conductive block 224 , so that static electricity on the assembly frame 221 can be discharged through the conductive block 224 .

[0066] In this embodiment, when installing an accessory, the positioning frame 212 is pushed upward to free the top of the limiting rod 211. The required landing gear 214 is then inserted into the limiting rod 211. The first spring 213 then rebounds, pushing the positioning frame 212 into the limiting rod 211 to seal it. The blocking bar 232 is then pushed backward to expose the installation area of ​​the assembly frame 221. The accessory is then installed inside the assembly frame 221. The second spring 233 then pushes the blocking bar 232 back to close the assembly frame 221. The landing gear 214 is then pushed up and down to adjust the height of the accessory. Once in place, the positioning rod 215 is inserted into the positioning slot 216 to secure it. The assembly frame 221 is then pulled forward and backward to adjust the front-to-back position of the accessory. The fastening bolt 222 is then tightened to secure it. During normal operation, if the accessories generate static electricity, the static electricity can be introduced into the conductive block 224 through the assembly frame 221, then introduced into the conductive block 224 and the conductive slot 225 through the conductive block 224, and then discharged through the ground wire 226, thereby achieving static electricity processing.

[0067] Next, please refer to Figure 14-17 The center of gravity adjustment assembly 30 includes a base 31 fixedly connected to the bottom of the body 111, the bottom of the base 31 is fixedly connected to a support leg 32, the bottom of the support leg 32 is fixedly connected to a pressure sensor 33, the inner cavity of the base 31 is slidably connected to a counterweight block 34, the middle part of the counterweight block 34 is slidably connected to a longitudinal frame 35, the longitudinal frame 35 is slidably connected to the inner cavity of the base 31, the rear inner cavity of the longitudinal frame 35 is threadedly connected to a first screw rod 36, the first screw rod 36 is rotatably connected to the rear side of the inner cavity of the base 31, the top of the counterweight block 34 is slidably connected to a transverse frame 37, the transverse frame 37 is slidably connected to the top of the inner cavity of the base 31, the right side of the transverse frame 37 is threadedly connected to a second screw rod 38, and the second screw rod 38 is rotatably connected to the right side of the inner cavity of the base 31.

[0068] It should be noted that the moving trajectory of the transverse frame 37 is forward and backward movement, while the moving trajectory of the longitudinal frame 35 is left and right movement, so that the position of the counterweight block 34 can be adjusted arbitrarily when the two sets of screw rods are fixed.

[0069] In this embodiment, after the equipment is installed, the pressure of the four legs 32 is detected by the pressure sensor 33 to obtain the offset data of the center of the body 111. If the offset is too large, the first screw rod 36 and the second screw rod 38 can be rotated to drive the longitudinal frame 35 and the transverse frame 37 to move, so as to adjust the position of the counterweight block 34 and then adjust the center of gravity of the device to ensure the stability of the device operation.

[0070] The working principle of the present invention is as follows: when installing an accessory, the positioning frame 212 can be pushed up to clear the top of the limit rod 211. The required landing gear 214 is then inserted into the limit rod 211. The blocking bar 232 is then pushed back to reveal the installation area of ​​the assembly frame 221. The accessory is then installed inside the assembly frame 221. The landing gear 214 is then pushed up and down to adjust the height of the accessory. Once in place, the positioning rod 215 is inserted into the positioning slot 216 to secure it. The assembly frame 221 is then pulled forward and backward to adjust the front-to-back position of the accessory, and then the fastening bolt 222 is tightened to secure it. If the accessory generates static electricity, the static electricity can be introduced into the conductive block 224 through the assembly frame 221, and then into the conductive block 224 and conductive slot 225 through the conductive block 224. It is then discharged through the ground wire 226, thus achieving static control. After the equipment is installed, the pressure of the four legs 32 is detected by the pressure sensor 33 to obtain the offset data of the center of the body 111. If the offset is too large, the position of the counterweight 34 can be adjusted by rotating the first screw 36 and the second screw 38 to drive the longitudinal frame 35 and the transverse frame 37 to move, thereby adjusting the center of gravity of the device to ensure the stability of the device operation. During daily maintenance, the maintenance door 115 and the cabinet door 112 can be opened at the same time to facilitate the inspection and maintenance of the internal electrical components. The cover 114 can be easily disassembled to facilitate the insertion of additional cables into the device through the additional wire groove 113. At the same time, the motor 123 drives the fan blades 124 to rotate, thereby generating airflow, sucking in external air through the filter 122, and exhausting the internal hot air through the vent 125 to achieve a good heat dissipation effect.

[0071] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
