[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] As shown in the figure, a display stand comprises a support plate 1 and a suspension plate 2. The support plate 1 has an inlay groove 11 in the middle, and elastic first snap-in lugs 22 are provided on both the front and rear sides of the suspension plate 2. A snap-in groove 13 is provided on the support plate 1 at a position corresponding to the first snap-in lug 22 and communicating with the inlay groove 11. The suspension plate 2 is embedded in the inlay groove 11, and the first snap-in lug 22 is snapped into the snap-in groove 13. In this embodiment, the display stand is configured as two parts, the support plate 1 and the suspension plate 2. The suspension plate 2 is inlaid in the inlay groove 11 of the support plate 1, and the first snap-in lug 22 is engaged with the snap-in groove 13 to connect the suspension plate 2 to the inlay groove 11. Due to the elastic action of the first snap-in lug 22, the suspension plate 2 is pressed against the display cover 4 when pressed downwardly by the display cover 4, thereby ensuring that the digital display content is displayed accurately and clearly, and effectively avoiding the occurrence of ghosting, misaligned images, light leakage, etc.

[0030] On the upper side of the support plate 1, a limiting groove 12 communicating with the embedding through groove 11 and the clamping groove 13 is provided around the embedding through groove 11. Along the peripheral side walls of the upper part of the support plate 1, a limiting edge 21 extends outward. The lower part of the support plate 1 is embedded in the embedding through groove 11, and the limiting edge 21 is lapped in the limiting groove 12. A gap is provided between the outer side wall of the limiting edge 21 and the side wall of the limiting groove 12, which is convenient for the installation of the floating plate 2 on the support plate 1.

[0031] The first clamping lug plate 22 includes a V-shaped elastic part 221 and an inverted L-shaped support part 222. One end of the elastic part 221 is fixedly connected to the limiting edge 21, and the other end is fixedly connected to the bottom of the vertical section of the support part 222. And the upper surface position of the horizontal section of the support part 222 is lower than the upper surface position of the floating plate 2. A lapping groove 15 communicating with the clamping groove 13 is provided on the upper side of the support plate 1 corresponding to the outside of the clamping groove 13. The elastic part 221 and the vertical section of the support part 222 are embedded in the clamping groove 13, and the horizontal section of the support part 222 is lapped in the lapping groove 15. In this embodiment, when the floating plate 2 is subjected to a downward extrusion force, a slight deformation can occur at the elastic part 221, ensuring that the floating plate 2 fits upward against the display cover 4.

[0032] Positioning grooves 14 communicating with the limiting groove 12 are provided on the inner walls of the left and right sides of the embedding through groove 11. And on one side of the front and rear sides inside the corresponding positioning groove 14 at the bottom of the limiting edge 21, a positioning column 25 is vertically provided, and the positioning column 25 is inserted into the corresponding positioning groove 14. In this embodiment, the positioning column 25 is inserted into one side of the positioning groove 14, making the positioning column 25 deviate from the center relative to the positioning groove 14, ensuring the correct installation direction of the floating plate 2 and effectively avoiding the reverse installation of the floating plate 2.

[0033] A plurality of connecting through grooves 16 are uniformly provided at the bottom of the support plate 1. An installation ear 17 is fixedly connected in each connecting through groove 16. And a first gap is provided between both sides of the installation ear 17 and the side walls of both sides of the connecting through groove 16. And an installation edge 171 protrudes outward at the outer side of the bottom of the installation ear 17. And a U-shaped groove is provided on the limiting edge 21 corresponding to the outer side wall of the installation ear 17. Such a design of the installation ear 17 facilitates the deformation of the installation ear 17 to make the installation edge 171 be clamped into the installation groove 31 on the inner wall of the bottom case 3.

[0034] The limiting edge 21 has grooves 23 on its left and right sides, opening outward. These grooves 23 are offset from the corresponding positioning grooves 14. A second snap-fitting lug 24 is positioned within the grooves 23. One end of the second snap-fitting lug 24 is fixed to one side of the groove 23, with a second gap between the other end and the other side of the groove 23. A third gap is also formed between the side facing the bottom of the groove 23 and the bottom of the groove 23. A downwardly projecting boss 241 is formed at the bottom of the second snap-fitting lug, near the second gap. The boss 241 abuts against the bottom sidewall of the limiting groove 12. In this embodiment, since the floating board 2 has a rectangular structure, the area on the wide sides, i.e., the areas on the left and right sides of the floating board 2 corresponding to the support board 1, is relatively small, making it unsuitable to install a structure such as the first snap-fitting lug 22. Therefore, the second snap-fitting lug 24 ensures that the left and right sides of the floating board 2 are firmly abutted against the support board 1 within the limiting grooves 12, further enhancing the stability of the floating board 2 on the support board 1.

[0035] The upper surface of the second snap-fit ear plate 24 is lower than the upper surface of the floating board 2, and the lower surface is flush with the lower surface of the limiting edge 21. The lower surface of the boss 241 is lower than the lower surface of the limiting edge 21, ensuring that when the floating board 2 is installed on the support plate 1, the second snap-fit ear plate 24 can be deformed so that the boss 241 is pressed against the bottom side wall of the limiting groove 12.

[0036] A clamping groove 18 is further provided at the outer edge of the limiting edge 21 for clamping onto the clamping block 32 on the bottom shell 3 to limit the support plate 1 .

[0037] In this embodiment, the mounting ear 17 and the support plate 1 are an integrally formed structure; the first clamping ear plate 22, the positioning column 25 and the suspension plate 2 are an integrally formed structure.

[0038] In this embodiment, the suspension board 2 is made of PPO or ABS plastic. Since the first and second clip ear plates 22 and 24 are designed to be thin, they have a certain elasticity and can deform to a certain extent without breaking.

[0039] The present application also provides a digital instrument display screen, including the above-mentioned display bracket, and also includes a bottom shell 3, a circuit board 5, a display sticker 6 and a display cover 4. The display bracket is fixed to the upper opening of the bottom shell 3, the circuit board 5 is fixed to the bottom of the floating board 2, the display sticker 6 is affixed to the upper surface of the floating board 2, the display cover 4 is buckled and fixed to the upper side of the bottom shell 3, and the lower surface of the top plate of the display cover 4 is pressed against the display sticker 6.

[0040] In this embodiment, the fixing of the display bracket on the bottom shell 3 and the fixing and installation of the display cover 4 on the bottom shell 3 are conventional technical means that can be mastered by those skilled in the art, and the innovation of this application is not here, so the specific connection structure will not be repeated here.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
