Specific implementation mode

[0022] The following further elaborates on the present utility model in detail in conjunction with the attached drawings and specific embodiments.

[0023] Embodiment:

[0024] As Figures 1 to 7 shown, this embodiment provides an insertable LED light board, including a mounting box 1. A mounting frame 2 is provided at the top of the mounting box 1. The mounting frame 2 is in a U shape. The middle plate of the mounting frame 2 is connected to the top of the mounting box 1, and the left and right side plates of the mounting frame 2 are perpendicular to the top of the mounting box 1. A top plate 3 is detachably connected to the top of the mounting frame 2. A light-transmitting plate 4 and display boards 5 located on the front and rear sides of the light-transmitting plate 4 are provided in the square frame position surrounded by the top plate 3 and the mounting frame 2. Grooves 6 are provided along the inner side of the top plate 3 and the mounting frame 2 in the length direction. The outer edges of the light-transmitting plate 4 and the display boards 5 are placed in the grooves 6. An LED light strip 7 leading to the groove 6 in the middle plate of the mounting frame 2 is provided at the top of the mounting box 1. Support plates 8 are respectively provided at the left and right ends of the bottom of the mounting box 1. A pair of rotating plates 9 are rotatably connected to the middle of the bottom of the mounting box 1 through damping hinges. A hanging ring 10 is provided at the end of the rotating plate 9 far from the damping hinge. When the mounting box 1 is placed upright, the support plate 8 abuts against the placement surface. When the mounting box 1 is hung upside down, the hanging ring 10 is penetrated by the hanging piece 11.

[0025] Through the combined use of the mounting frame 2 and the top plate 3, the quick installation and disassembly of the light-transmitting plate 4 and the display boards 5 are realized, and the display boards 5 to be displayed can be quickly replaced. When installing the light-transmitting plate 4 and the display boards 5, first overlap and combine the light-transmitting plate 4 and the display boards 5. Then, place the top or bottom edges of the light-transmitting plate 4 and the display boards 5 into the groove 6 of the top plate 3. Then, insert the light-transmitting plate 4 and the display boards 5 into the mounting frame 2 in such a way that the outer edges on the left and right sides of the light-transmitting plate 4 and the display boards 5 are aligned with the grooves 6 on the left and right side plates of the mounting frame 2. When the installation of the light-transmitting plate 4 and the display boards 5 is completed, the top plate 3 and the top of the mounting frame 2 are combined, and finally the connection between the top plate 3 and the mounting frame 2 is fixed. Through the combined use of the support plate 8, the rotating plate 9 and the hanging ring 10, the mounting box 1 can be placed upright or hung upside down, and the appropriate placement method can be selected according to actual needs. When there is a flat placement surface, the mounting box 1 can be placed upright. When there is a hanging piece 11, the mounting box 1 can be hung upside down.

[0026] Further, insertion grooves 12 are provided at the outer tops of the left and right side plates of the installation frame 2. A sliding groove 13 is provided on the insertion groove 12. The direction of the sliding groove 13 is perpendicular to the direction of the insertion groove 12. A sliding block 14 is slidably connected to the sliding groove 13. The outer end of the sliding block 14 can extend into the insertion groove 12. A spring A 15 is provided between the inner end of the sliding block 14 and the bottom of the sliding groove 13. Insertion blocks 16 corresponding to the insertion grooves 12 are provided at the left and right ends of the top plate 3. A docking groove 17 corresponding to the sliding block 14 is provided on the insertion block 16. When the insertion block 16 is completely placed into the insertion groove 12, the docking groove 17 is docked with the sliding groove 13, and the outer end of the sliding block 14 extends into the docking groove 17.

[0027] Through the combined use of the sliding block 14, the spring, and the docking groove 17, the elastic force of the spring pushes the sliding block 14 into the docking groove 17, thereby realizing the locking of the insertion block 16 placed in the insertion groove 12, and thus fixing the connection between the top plate 3 and the installation groove. When installing the top plate 3, during the process of placing the insertion block 16 into the insertion groove 12, the staff pulls the sliding block 14 back into the sliding groove 13. After the insertion block 16 is completely placed into the insertion groove 12, the staff releases the sliding block 14, and the sliding block 14 extends into the docking groove 17 under the action of the spring. When removing the top plate 3, the staff pulls the sliding block 14 back, so that the sliding block 14 is withdrawn from the docking groove 17, and the sliding block 14 is released after the insertion block 16 is removed from the insertion groove 12. Specifically, generally, corresponding inclined surfaces are provided at the insertion end of the insertion block 16 and the outer end of the sliding block 14. During the process of placing the insertion block 16 into the insertion groove 12, the insertion block 16 can push the sliding block 14 back into the sliding groove 13 along the inclined surface, without the need for the staff to manually pull back the slider, making it more convenient to use.

[0028] Further, the end of the support plate 8 is rotatably connected to the bottom of the installation box 1. A magnetic block 18 is provided inside the bottom of the installation box 1 on the inner side of the support plate 8. When the support plate 8 rotates inward to be retracted, the magnetic block 18 abuts against the support plate 8 and magnetically attracts the support plate 8. A limiting block 19 is provided on the surface of the support plate 8 facing away from the magnetic block 18. When the support plate 8 rotates outward to be unfolded, the limiting block 19 abuts against the bottom of the installation box 1.

[0029] When the installation box 1 is suspended upside down, the idle support plate 8 can be rotated inward to be retracted, and the support plate 8 is attracted by the magnetic block 18, which is convenient for placing the support plate 8. When the installation box 1 is placed upright, the support plate 8 rotates outward to be unfolded, and the limiting block 19 helps the support plate 8 stop at an angle convenient for the installation box 1 to be placed flat on the placement surface, facilitating the positioning of the support plate 8.

[0030] Further, a pressing plate 20 is slidably connected to the inner ring of the hanging ring 10. A spring B 21 is provided between the pressing plate 20 and the lower edge of the inner ring of the hanging ring 10.

[0031] By using the pressing plate 20 and the spring B21 in combination, the hanging part 11 generally abuts against the upper edge of the inner ring of the hanging ring 10. The spring B21 acts to press the pressing plate 20 against the hanging part 11, thereby increasing the friction between the hanging ring 10 and the hanging part 11, reducing the probability of the hanging ring 10 sliding on the hanging part 11, and improving the stability of the installation box 1 when it is inverted and hung.

[0032] The working principle and usage process of the present utility model:

[0033] Select the placement method of the installation box 1 according to the display requirements and site conditions. Select the insertion direction of the display panel 5 according to the placement method of the installation box 1. Install the overlapping and combined light-transmitting plate 4 and display panel 5 on the top plate 3. Through the restriction of the top plate 3, prevent the overlapping light-transmitting plate 4 and display panel 5 from spreading. Then fully insert the light-transmitting plate 4 and display panel 5 into the installation frame 2. Next, fix the connection between the matching top plate 3 and installation frame 2. Place the installation box 1 properly and turn on the LED light strip 7 to illuminate the display panel 5.

[0034] The above are only specific application examples of the present utility model and do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present utility model.
