[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6 As shown, the utility model can be implemented through the following embodiments: a power box for an LED display screen, comprising an installation box body 1 and a power supply 3, the installation box body 1 is divided into a main body 11 and a slide plate 12, the slide plate 12 is connected to the main body 11 by screws 13, the main body 11 is provided with a slide rail 111, the slide plate 12 is provided with a slider 121, a mounting plate 2 is installed on the slide plate 12, a limiting rod 21 is provided on the mounting plate 2, the power supply 3 is provided with a mounting frame 31, the mounting frame 31 is provided with a limiting groove 311, an inspection port 14 is opened on the installation box body 1, a cover plate 4 is installed on the inspection port 14, a card block 41 is provided on the cover plate 4, and a card slot 15 is provided on the main body 11.

[0023] The design of the installation box body 1 being divided into a main body 11 and a slide plate 12 facilitates the installation and disassembly of the power supply 3. The power supply 3 is placed in the installation frame 31, and the installation frame 31 is installed on the installation plate 2. The limit rod 21 on the installation plate 2 cooperates with the limit groove 311 on the installation frame 31 to limit the displacement of the power supply 3 on the plane to prevent the power supply 3 from being displaced or falling off during the installation process. The setting of the inspection port 14 is used to facilitate wiring after the power supply 3 enters the main body 11, as well as subsequent maintenance.

[0024] like Figure 1 and Figure 3 As shown, the mounting plate 2 is provided with supporting feet 22, and the supporting feet 22 fix the mounting plate 2 on the slide plate 12 through bolts 5. The setting of the mounting plate allows the power supply 3 to be mounted on the mounting plate and separated from the slide plate, so that the power supply 3 does not need to be fixedly connected to the slide plate through a connecting piece. The setting of the supporting feet 22 allows space between the power supply 3 and the slide plate, which is convenient for heat dissipation and easy for maintenance personnel to remove the power supply 3.

[0025] like Figure 1 and Figure 2 As shown, a handle 312 is provided on the mounting frame 31. The design of the handle 312 facilitates the removal of the power supply 3 from the mounting plate 2, and facilitates the replacement and maintenance of the power supply 3.

[0026] like Figure 3 and Figure 6 As shown, the limiting rod 21 is covered with a buffer sleeve 6, and there is a clearance fit between the buffer sleeve 6 and the limiting groove 311. The setting of the buffer sleeve 6 can absorb the vibration of the power supply 3 during the installation process, and prevent wear between the limiting groove 311 and the limiting rod 21, which will increase the tolerance between the limiting groove 311 and the limiting rod 21 and make it impossible to limit; at the same time, the buffer sleeve 6 buffers between the limiting rod 21 and the limiting groove 311 to slow down the speed of the power supply 3 falling during installation, and prevent the power supply 3 from being damaged by impact.

[0027] like Figure 1 and Figure 5 As shown, a protection pad 1 313 is fixed to the bottom surface of the mounting frame 31, a protection pad 23 is provided on the mounting plate 2, and an oblique opening 7 is provided on the protection pad 1 313 and the protection pad 2 23. The protection pad 1 313 and the protection pad 2 23 are provided for buffering, preventing the mounting frame 31 and the mounting plate 2 from being worn, and preventing the power supply 3 from being impacted. The oblique opening 7 is designed to separate the protection pad 1 313 and the protection pad 2 23 when disassembling the power supply 3, thereby increasing the disassembly speed.

[0028] like Figures 1 to 4 As shown, the cover plate 4 is provided with a connecting rod 8, a fixing block 81 is fixed to the connecting rod 8, a buffer pad 811 is provided on the fixing block 81, and the buffer pad 811 contacts the power supply 3. After the fixing block 81 contacts the power supply 3, the buffer pad 811 fits the power supply 3, absorbs the reaction force brought by the power supply 3, and prevents the power supply 3 from being squeezed and damaged. The fixing block 81 limits the movement of the power supply 3 along the Y axis during the installation process, and protects the power supply 3 from being damaged during the installation process.

[0029] The working principle of the utility model is as follows: the mounting plate 2 is mounted on the slide plate 12, and then the power supply 3 is placed on the mounting plate 2, the limiting groove 311 of the mounting frame 31 of the power supply 3 is inserted into the limiting rod 21, and after the slide plate 12 is sent into the main body 11, the power supply 3 box is wired through the inspection port 14. During the wiring, the slide plate 12 can be slid to provide an operating space. After the wiring is completed, the slide plate 12 and the main body 11 are fixedly connected by screws 13, and finally the cover plate 4 is covered so that the card block 41 is inserted into the card slot 15, and the fixing block 81 presses the power supply 3.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
