The power box shell main body and the LED display screen box frame 4 are locked through the anti-loosening insert 122. In this way, the positioning function is realized, and the locking effect is also achieved. Combined with the sunken design, the waterproof and dustproof capability of the LED display screen power box is greatly improved.Figure 2 Still further in combination Figure 3 , Figure 3 The anti-loosening insert structure schematic view. The spring 123 is arranged between the anti-loosening insert 122 and the positioning column 121, the anti-loosening insert 122 comprises a nut 1221 and a screw rod 1222, the screw rod 1222 is provided with external threads at the end away from the nut 1221, during installation, the screw rod 1222 is inserted into the mounting hole of the LED display screen box frame 4, and the power box shell body 1 is locked with the LED display screen box frame 4 through cooperation of the external threads on the screw rod 1222 with the internal threads of the mounting hole; this design makes the anti-loosening insert 122 not easy to fall off during installation and disassembly, and the external threads provided at the end of the screw rod 1222 away from the nut 1221 can improve installation efficiency, and the anti-loosening insert 122 can be pushed out by the spring 123 during disassembly, thereby providing tactile feedback to the operator, so that the operator knows that the disassembly is completed without needing to observe with naked eyes.

[0028] Reference is made again Figure 2 Still further in combination Figure 4 , Figure 4 The second view angle structure schematic view of the utility model. The power box shell body 1 is provided with symmetrical snap connection parts 13 at both sides, the snap 131 is arranged on the snap connection part 13, and the snap 131 is rotationally connected with the snap connection part 13; the power box shell body 1 is locked with the LED display screen box frame 4 through the snap 131, and more preferably, two snaps 131 are arranged on each side of the power box shell body 1, so that stronger locking effect can be provided, the stable connection between the power box and the display screen is maintained, and the multiple snaps 131 can apply pressure at different positions, so that the power box is better attached to the surface of the LED display screen. Two locking modes are provided in the embodiment, in addition to the above-mentioned locking of the power box shell body 1 with the LED display screen box frame 4 by the anti-loosening insert 122, the power box shell body 1 can also be locked and fastened with the LED display screen box frame 4 by the snap, so that the user can select different modes according to actual needs, and if both modes are used, double protection can be realized, the power box shell body 1 is prevented from loosening, and the internal components of the power box shell body 1 are prevented from being exposed, thereby further reducing the safety risk.

[0029] Reference is made again Figure 2 and Figure 4The power supply box shell body 1 is provided with a power supply protruding portion 14 on each side of one end of the power supply box shell body 1. The power supply protruding portion 14 is internally provided with a power supply port which is inclined downward and matched with a power supply socket 141. The power supply socket 141 is arranged in the accommodating cavity. The power supply box shell body 1 is provided with a signal protruding portion 15 on each side of the other end of the power supply box shell body 1. The signal protruding portion 15 is internally provided with a signal port which is inclined downward and matched with a signal socket 151. The signal socket 151 is arranged in the accommodating cavity. The inclined downward design is beneficial to interface connection and operation, and effectively reduces the thickness of the power supply box. The power supply box shell body 1 is further provided with a spare signal interface 16 on the end close to the signal protruding portion 15.

[0030] Reference is made to Figure 4 The power supply box shell body 1 is provided with a display 18 which is electrically connected with the power supply 3. The display 18 is used to display the signal conditions of each interface in the power supply box, and is used to intuitively reflect the use of the power supply box, so that the staff can know the real-time condition of the power supply box in time, and the maintenance and replacement of the power supply box are ensured. The power supply box shell body 1 is provided with symmetrical holding grooves 17 or finger grooves on both sides, which is convenient for users to grab or carry the power supply box. The power supply box shell body 1 is internally provided with a connecting column 19. The adapter board 2 is fastened on the power supply box shell body 1 through the cooperation of the fastener and the connecting column 19. The connecting column 19 is pre-set, so that the installation process is more simple and fast. Only the fastener needs to be aligned with the connecting column 19 and tightened, and the assembly can be completed, which reduces the operation difficulty. The power supply 3 and the adapter board 2 are detachably connected through the fastener. The detachable design is convenient for subsequent maintenance work.

[0031] In summary, the embodiment adopts a sinking design to embed the power supply box of the LED display screen into the mounting groove of the LED display screen box frame, so that the thickness of the whole LED display screen system is thinner. The positioning column 121 originally arranged in the power supply box shell body 1 is improved. The positioning column 121 is moved to the outside of the power supply box shell body 1 to save the internal space of the power supply box shell body 1. The positioning column 121 is designed into a hollow cylindrical structure, and a anti-loosening insert is sleeved in the positioning column 121. The power supply box shell body is locked with the LED display screen box frame through the anti-loosening insert 122. In this way, the positioning function and the locking effect are realized. Combined with the sinking design, the waterproof and dustproof capability of the power supply box of the LED display screen is greatly improved.

[0032] The above merely illustrates the implementation modes of the present application and is not used to limit the present application. The present application can be changed and modified in various ways for those skilled in the art.
