[0030] Figures 1 to 5 This is a schematic diagram of some embodiments of a display power supply box with a waterproof structure according to the present invention.

[0031] Reference Figures 1 to 5 and mainly refer to Figure 3 , Figure 4 and Figure 5 According to this embodiment, a display power supply box with a waterproof structure (sometimes referred to as a display power supply box in the following embodiments) is provided. A display power supply box with a waterproof structure includes a box body 100, a box cover 200, and a first sealing structure. In this embodiment, the box body 100 is generally rectangular in shape, and a receiving cavity 110 is provided inside the box body 100. A connecting end 120 is provided on the front or rear side of the box body 100. The connecting end 120 has an opening 130 that communicates with the receiving cavity 110. The shape of the box cover 200 matches the shape of the connecting end 120. The lower part of the box cover 200 is rotatably connected to the box body 100. The box cover 200 can be flipped upward or downward relative to the box body 100. When the box cover 200 is flipped upward relative to the box body 100 and covers the outer periphery of the connecting end 120, the box cover 200 closes the opening 130 of the connecting end 120. When the box cover 200 is flipped downward relative to the box body 100 and the connecting end 120 is dislodged from the inside of the box cover 200, the box cover 200 opens the opening 130 of the connecting end 120.

[0032] The first sealing structure is disposed between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the lid 200. When the lid 200 is flipped upward relative to the box body 100 and covers the outer periphery of the connecting end 120, the first sealing structure seals the gap between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the lid 200.

[0033] In this embodiment, the power supply box for the display screen has a first sealing structure between the upper surface of the outer wall of the connecting end 120 of the box body 100 and the upper surface of the inner wall of the box cover 200. When the box cover 200 covers the outer periphery of the connecting end 120 of the box body 100, the first sealing structure seals the gap between the upper surface of the outer wall of the connecting end 120 of the box body 100 and the upper surface of the inner wall of the box cover 200. Therefore, when rainwater splashes onto the upper surface of the box body 100, the rainwater cannot flow along the upper surface of the box body 100 and seep into the interior of the box body 100 from the gap between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the box cover 200. This improves the waterproof performance of the power supply box for the display screen and helps protect the power supply component 600 placed inside the power supply box for the display screen.

[0034] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 To better seal the gap between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the cover 200, in some embodiments of this invention, the first sealing structure includes a first sealing strip 310. The first sealing strip 310 is a silicone or rubber sealing strip, disposed on the upper surface of the outer wall of the connecting end 120, and extends along the length of the box body 100. The length of the first sealing strip 310 is substantially the same as the length of the box body 100, or slightly longer than the length of the box body 100. When the cover 200 closes the opening 130 of the connecting end 120 and covers the outer periphery of the connecting end 120, the first sealing strip 310 seals the gap between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the cover 200. By adopting the above structure, the structure of the display power box in this embodiment can be greatly simplified, facilitating the manufacturing of the display power box and helping to reduce the production cost of the display power box.

[0035] Reference Figure 2 , Figure 3 and Figure 5In some embodiments of this utility model, an installation groove 121 extending along the length of the box body 100 is provided on the upper surface of the outer wall of the connecting end 120, and the first sealing strip 310 is embedded in the installation groove 121. By providing the installation groove 121 on the upper surface of the outer wall of the connecting end 120, the first sealing strip 310 can be positioned and installed in the installation groove 121, which facilitates the positioning and installation of the first sealing strip 310. At the same time, when the box cover 200 covers the outer periphery of the connecting end 120, it can effectively prevent the first sealing strip 310 from shifting relative to the connecting end 120, and ensure the sealing effect of the first sealing strip 310 in sealing the gap between the upper surface of the outer wall of the connecting end 120 and the upper surface of the inner wall of the box cover 200.

[0036] In some embodiments of this utility model, the cross-sectional shape of the first sealing strip 310 is D-shaped. By adopting the above structure, the first sealing strip 310 is round at the bottom and round at the top, and the interior of the first sealing strip 310 is hollow. The square part of the lower part of the first sealing strip 310 is embedded in the mounting groove 121, while the upper part of the first sealing strip 310 is an arc-shaped part. When the box cover 200 covers the outer periphery of the connecting end 120, the arc-shaped part of the upper part of the first sealing strip 310 abuts against the upper surface of the inner wall of the box cover 200. Moreover, since the interior of the first sealing strip 310 is hollow, when the upper surface of the inner wall of the box cover 200 presses against the upper part of the first sealing strip 310, the upper part of the first sealing strip 310 is compressed and deformed. Therefore, the upper part of the first sealing strip 310 can better fit against the upper surface of the inner wall of the box cover 200, further improving the sealing performance of the first sealing strip 310.

[0037] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5To further improve the sealing and waterproof performance of the display power box, some embodiments of the present invention further include a second sealing structure. The second sealing structure is disposed between the end face of the connecting end 120 facing the cover 200 and the inner bottom wall of the cover 200. When the cover 200 is flipped upward relative to the box body 100 and covers the outer periphery of the connecting end 120, the second sealing structure seals the gap between the connecting end 120 and the inner bottom wall of the cover 200. By adopting the above structure, when the cover 200 is fitted over the outer periphery of the connecting end 120, the first sealing structure seals the gap between the upper surface of the outer wall of the connecting end 120 of the main body 100 and the upper surface of the inner wall of the cover 200, which is the first sealing. At the same time, the second sealing structure seals the gap between the end face of the connecting end 120 and the inner bottom wall of the cover 200, which is the second sealing. Therefore, the display power box of this embodiment has a double sealing structure. Even if the first sealing structure fails, the second sealing structure can still seal the gap between the end face of the connecting end 120 and the inner bottom wall of the cover 200, effectively preventing rainwater from entering the interior of the main body 100. Therefore, the sealing and waterproof performance of the display power box of this embodiment is greatly improved.

[0038] To simplify the structure of the second sealing structure, in some embodiments of this invention, the second sealing structure includes a second sealing gasket 320, which is a silicone or rubber gasket. The shape of the second sealing gasket 320 is adapted to the shape of the connecting end 120, and the second sealing gasket 320 is disposed on the inner bottom wall of the cover 200 at a position corresponding to the connecting end 120. When the cover 200 is fitted over the outer periphery of the connecting end 120, the connecting end 120 tightly adheres to and presses against the second sealing gasket 320. By adopting the above structure, the manufacturing of the second sealing structure is facilitated, which helps to reduce the production cost of the display power supply box.

[0039] In some embodiments of this utility model, an annular abutment portion 122 is provided at the end of the connecting end 120 that abuts against the second sealing gasket 320. The annular abutment portion 122 is arranged circumferentially around the connecting end 120. When the cover 200 is fitted over the outer periphery of the connecting end 120, the annular abutment portion 122 tightly adheres to and presses against the second sealing gasket 320. By adopting the above structure, when the connecting end 120 abuts against the second sealing gasket 320, the annular abutment portion 122 can increase the contact area between the connecting end 120 and the second sealing gasket 320. Consequently, the second sealing gasket 320 can better seal the gap between the end face of the connecting end 120 and the inner bottom wall of the cover 200, thereby enhancing the sealing performance of the second sealing structure.

[0040] In some embodiments of this utility model, the annular abutment portion 122 is arranged at the connecting end 120 extending from the inside of the receiving cavity 110 outwards. For example... Figure 5As shown, the annular abutment portion 122 extends upward from the end of the connecting end 120, thereby forming a protrusion at the end of the connecting end 120. At this time, a groove 123 is formed between the end of the connecting end 120 and the first sealing strip 310. When the cover 200 covers the outer periphery of the connecting end 120, if the first sealing strip 310 fails and some rainwater flows into the groove 123, the groove 123 can intercept most of the rainwater. At the same time, the second sealing gasket 320 can seal the gap between the end face of the connecting end 120 and the inner bottom wall of the cover 200, thereby preventing rainwater from seeping into the interior of the box body 100, which greatly improves the sealing performance of the display power box of this embodiment.

[0041] Reference Figures 1 to 5 In some embodiments of this utility model, at least one set of latching components is provided between the upper part of the cover 200 and the upper part of the body 100. The latching components include a latch 410 and a latch seat 420 that can engage with each other. One of the latch 410 and the latch seat 420 is located on the upper part of the body 100, and the other is located on the upper part of the cover 200. Specifically, when the latch 410 is located on the upper part of the body 100, the latch seat 420 is located on the upper part of the cover 200, or the latch 410 is located on the upper part of the cover 200, and the latch seat 420 is located on the upper part of the body 100. By adopting the above structure, when the cover 200 is placed over the outer end of the connecting end 120, the latch 410 and the latch seat 420 engage, thereby preventing the cover 200 from swinging downward relative to the body 100 and opening the opening 130, thus ensuring the sealing performance of the display power box.

[0042] In some embodiments of this utility model, the number of latching components is two or more, and all latching components are arranged evenly at intervals along the length of the box body 100; all latches 410 are arranged on the upper part of the box cover 200, and all latch seats 420 are arranged on the upper part of the box body 100, and all latch seats 420 are connected to form a whole. In this embodiment, the number of latching components is three sets, and the three sets of latching components are arranged evenly at intervals along the length of the box body 100; all three latches 410 are arranged on the upper part of the box cover 200, and all three latch seats 420 are arranged on the upper part of the box body 100, and the three latch seats 420 are connected to form a whole. By adopting the above structure, it is convenient to manufacture the latch seats 420, and the three sets of latching components can better lock the box cover 200 to the box body 100, effectively preventing the box cover 200 from swinging downward relative to the box body 100 and opening the opening 130, further improving the sealing performance of the display power box.

[0043] Reference Figures 1 to 6 A display screen according to certain embodiments of the present invention includes a display screen body 500, and the display screen body 500 is equipped with the aforementioned display screen power supply box.

[0044] Since the display screen adopts all the technical solutions of the display power box of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0045] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
