[0030] like Figures 1 to 3 The LED display screen with a waterproof structure shown in the figure includes an outer shell 100, an end cover 200, a first partition plate 300, a second partition plate 400, and an LED screen body 500 arranged in the outer shell 100.
[0031] A cavity 10 is formed on the housing 100. The cavity 10 includes a main cavity 12, a port 11 disposed on the left side of the main cavity 12, and an inner cavity 13 disposed on the right side of the main cavity 12. An outer baffle 20 is disposed at the right port of the inner cavity 13. A slot structure for heat dissipation is disposed on the outer baffle 20.
[0032] The front end of the mold cavity 10 is an open port, that is, the front end of the main cavity 12, the front end of the port 11 and the front end of the inner cavity 13 are all open structures. The end cap 200 can be sealed on the open port to block the front end of the mold cavity 10 to form a closed end ( Figure 1 In the illustrated solution, the end cover 200 is translated to the left, so that the end cover 200 can be sealed at the front end of the housing 100).
[0033] The LED screen body 500 is arranged in the main cavity 12, and the upper and lower parts of the port 11 are formed with edge arms to prevent the LED screen body 500 from falling off from the main cavity 12 (to the left). The vertical extension distance of the inner cavity 13 is smaller than the vertical extension distance of the main cavity 12, so the LED screen body 500 can be prevented from falling off from the main cavity 12 (to the right).
[0034] The first partition plate 300 and the second partition plate 400 are arranged alternately in the inner cavity 13 in the left-right direction. The first partition plate 300 is located on the right side of the second partition plate 400 and a left-right spacing is formed between the first partition plate 300 and the outer partition plate 20. Slot hole structures are provided on both the first partition plate 300 and the second partition plate 400. The slot hole structures on the first partition plate 300 and the slot hole structures on the second partition plate 400 can be multiple strip holes distributed alternately up and down and extending in the front-to-back direction; but at the same time, it is required that each strip hole provided on the second partition plate 400 corresponds to the spacing area between two adjacent strip holes provided on the first partition plate 300 (in left-view projection). In this way, the slot hole structures on the first partition plate 300 and the slot hole structures on the second partition plate 400 are arranged in a staggered relative manner. In most cases, the width of the strip grooves provided on the second partition plate 400 (the dimension in the vertical direction) is smaller than the spacing width (the dimension in the vertical direction) between two adjacent strip grooves provided on the first partition plate 300, so that the slot hole structure on the first partition plate 300 and the slot hole structure on the second partition plate 400 are formed in a relative distribution form that cannot be directly penetrated in the left-right direction. Similarly, the strip holes on the first partition plate 300 and the strip holes on the second partition plate 400 can be extended in the vertical direction and multiple strip holes can be distributed alternately in the front-back direction.
[0035] The upper and lower ends of the housing 100 are both formed with a profile groove 30, and a strip groove 40 is provided on the right end surface (outer end surface) of the outer partition 20 to connect the profile groove 30 provided at the upper end of the housing 100 with the profile groove 30 provided at the lower end of the housing. The strip grooves 40 are provided in plurality and are alternately arranged in the front-rear direction.
[0036] The bottom surface of the groove 30 disposed at the upper end of the housing 100 is arranged in a distribution form that is inclined downward from left to right (eg Figure 3 As shown, it contains two levels of inclined surfaces and transitions between the inclined surfaces through a gentle surface. The gentle surface can be a plane along the left and right directions or can be slightly inclined. However, any inclined surface and the inclined state are required to be inclined downward from left to right); the bottom surface of the groove 30 at the lower end of the housing 100 is arranged in a distribution form of being inclined upward from left to right (such as Figure 3 As shown, it contains two levels of inclined surfaces and a gentle surface transitions between the inclined surfaces. The gentle surface can be a plane along the left and right direction or can be slightly inclined. However, any inclined surface and the inclined state are required to be inclined from left to right and upward).
[0037] A plurality of drainage holes 121 are provided at the lower end of the main cavity 12 and communicate with the groove 30 provided at the lower end of the housing 100, so that the plurality of drainage holes 121 are alternately distributed along the front-to-back direction. The drainage holes 121 shown in the figure are provided with two layers in the front-to-back direction, and grooves can be formed at the upper ends of the two layers of drainage holes 121, so that rainwater intruding into the main cavity 12 can be better gathered at the drainage holes 121 and quickly and fully discharged to the outside.
[0038] A plurality of drainage grooves 131 are provided at the lower end of the inner cavity 13, which are connected to the profile groove 30 provided at the lower end of the outer shell 100 and the lower end of the strip groove 40, and the bottom surface of the drainage groove 131 is distributed in a downwardly inclined manner from left to right. The plurality of drainage grooves 131 are arranged alternately along the front-to-back direction. The upper end of the drainage groove 131 extends to the lower part of the second side partition 400 provided in the inner cavity 13. The drainage groove 131 can discharge rainwater flowing down from the board surface of the outer partition 20, the first partition 300, and the second partition 400 to the outside, which can effectively prevent rainwater from extending inward and sticking to the LED screen body 500, causing damage to the LED screen body 500.
[0039] On the front end surface of the housing 100, profile 1 60 is formed at the upper and lower ends respectively. Correspondingly, profile 2 90 is formed on the end cover 200 to match the two profile 1 60. An elastic sealing pad layer is provided on the profile 1 60. After the end cover 200 is fixedly sealed on the front end of the housing 100, the profile 1 60 and the profile 2 90 can be in close contact, and the elastic sealing pad layer is sandwiched in the middle to form a good contact sealing structure.
[0040] A recessed groove portion 80 is formed on the end surface of the end cover 200 corresponding to the matching end surface of the outer shell 100.
