[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0029] like Figures 1 to 5 As shown, an embodiment of this utility model discloses an LED display screen, including a bottom shell 1 and a face mask 2. The bottom shell 1 is provided with a plurality of first strip-shaped through holes 11, and a first support plate 12 is formed between every two adjacent first strip-shaped through holes 11. The face mask 2 is provided with a plurality of second strip-shaped through holes 21, and a second support plate 22 is formed between every two adjacent second strip-shaped through holes 21. At least one first snap-fit ​​structure 13 is provided on each of the two side walls of the same first support plate 12, and at least one second snap-fit ​​structure 23 is provided on each of the two side walls of the same second support plate 22. The second snap-fit ​​structure 23 passes through the first strip-shaped through hole 11 and snaps into the first snap-fit ​​structure 13.

[0030] The first support plate 12 has a first snap-fit ​​structure 13 on both sides, and the second support plate 22 has a second snap-fit ​​structure 23 on both sides. The second snap-fit ​​structure 23 is snapped to the first snap-fit ​​structure 13 to connect the face mask 2 to the bottom shell 1. This eliminates the need for screws, and the snap-fit ​​connection method makes disassembly and assembly convenient. This solves the problem in the prior art where the bottom shell 1 and face mask 2 in LED displays are inconvenient to disassemble and assemble due to the screw connection.

[0031] In this embodiment, the bottom of the first snap-fit ​​structure 13 is provided with a snap-fit ​​groove 131. The snap-fit ​​groove 131 is used for the second snap-fit ​​structure 23 to snap into place.

[0032] In this embodiment, the inner sidewall of the second snap-fit ​​structure 23 is provided with a buckle body 231 that mates with the snap-fit ​​groove 131. The second snap-fit ​​structure 23 engages with the snap-fit ​​groove 131 through the buckle body 231, thereby achieving a snap-fit ​​connection between the first snap-fit ​​structure 13 and the second snap-fit ​​structure 23.

[0033] In this embodiment, the inner sidewall of the second snap-fit ​​structure 23 is provided with a first guide groove 232 that mates with the outer sidewall of the first snap-fit ​​structure 13. The first guide groove 232 penetrates the top and bottom of the second snap-fit ​​structure 23, and the snap-fit ​​body 231 is disposed on the bottom wall of the first guide groove 232. To facilitate the snap-fit ​​between the snap-fit ​​body 231 and the snap-fit ​​groove 131, the second snap-fit ​​structure 23 slides along the outer sidewall of the first snap-fit ​​structure 13 via the first guide groove 232, thus providing a guiding function.

[0034] In this embodiment, the bottom wall of the guide groove is divided into a first region and a second region. The buckle body 231 is located in the first region, and the second region is configured as a hollow region 2321 that extends through the outer wall of the second buckle structure 23. Setting the second region as a hollow region 2321 saves costs during production and also provides better elasticity.

[0035] In this embodiment, the outer wall of the first snap-fit ​​structure 13 is provided with a positioning guide groove 132 for the snap-fit ​​body 231 to move toward the snap-fit ​​groove 131. In order to further allow the snap-fit ​​body 231 to move toward the snap-fit ​​groove 131, a positioning guide groove 132 is provided on the outer wall of the first snap-fit ​​structure 13, so that the snap-fit ​​body 231 can slide along the positioning guide groove 132 and reach the snap-fit ​​groove 131.

[0036] In this embodiment, the snap-fit ​​groove 131 is a hemispherical groove, and the snap-fit ​​body 231 is a hemispherical protrusion. The hemispherical groove and protrusion facilitate a smoother fit.

[0037] In this embodiment, a portion of the inner sidewall of the first snap-fit ​​structure 13 is removed to form a connection portion 133 between one sidewall and the bottom sidewall of the first support plate 12. This reduces the space occupied by the first snap-fit ​​structure 13 in the first strip-shaped through hole 11.

[0038] In this embodiment, the junction of the top and outer side wall of the first snap-fit ​​structure 13 is provided as a guide slope 134. The guide slope 134 facilitates the engagement of the first snap-fit ​​structure 13 with the second snap-fit ​​structure 23.

[0039] In this embodiment, the depth of the positioning guide groove 132 decreases from top to bottom. The upper part of the positioning guide groove 132 is relatively deep, which facilitates the insertion of the buckle 231 into the positioning guide groove 132. The lower part of the positioning guide groove 132 is relatively shallow, which facilitates the exit of the buckle 231 from the positioning guide groove 132 and into the snap-fit ​​groove 131.

[0040] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
