[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 3 As shown, a spliced LED box provided by an embodiment of the present invention includes at least four LED boxes 100 distributed in rows and columns and spliced together. Connectors are provided on the splicing surfaces of the LED boxes 100 relative to adjacent LED boxes 100.

[0026] The connectors include a first connector, a second connector, a third connector, and a fourth connector. The first and third connectors are positioned on two adjacent side surfaces of the LED box 100, the second connector is positioned on the side of the LED box 100 opposite the first connector, and the fourth connector is positioned on the side of the LED box 100 opposite the third connector. When two adjacent LED boxes 100 are spliced together, the first and second connectors cooperate to connect, and the third and fourth connectors cooperate to connect. The spliced LED box 100 shown in this embodiment has four LED boxes 100, with two LED boxes 100 in each column and row. In other embodiments, the spliced LED box 100 may also include a plurality of LED boxes 100, such as 9, 16, 25, or 36.

[0027] Compared with the prior art, when the spliced LED box 100 of the embodiment of the present invention is spliced, the first connecting member and the second connecting member are connected in coordination, and the third connecting member and the fourth connecting member are connected in coordination, thereby ensuring precise positioning between the boxes.

[0028] Specifically, the first connecting assembly includes a limiting slot 11 and a positioning pin hole 12, while the second connecting assembly includes a limiting slider 21 that fits within the limiting slot 11 and a positioning pin 22 that fits within the positioning pin hole 12. When two adjacent LED boxes 100 are joined, the limiting slider 21 slides along the limiting slot 11 to position the two adjacent LED boxes 100. Once the positioning is complete, the positioning pin 22 inserts into the positioning pin hole 12, thereby positioning the two adjacent LED boxes 100. This assembly sequence of first limiting and then positioning ensures precise horizontal and vertical positioning of the LED boxes 100.

[0029] The third connecting assembly includes a positioning post 31 and a limiting slot 32. The fourth connecting assembly includes a positioning hole 41 that matches the positioning post 31 and a limiting block 42 that matches the limiting slot 32. When two adjacent LED boxes 100 are spliced together, the positioning post 31 is inserted into the positioning hole 41, and the limiting block 42 is inserted into the limiting slot 32. The positioning post 31 and the positioning hole 41 cooperate to achieve the positioning of the two adjacent LED boxes 100. The limiting slot 32 and the limiting block 42 cooperate to further position the two adjacent LED boxes 100, thereby ensuring precise positioning between the LED boxes 100.

[0030] It should be noted that, in some other specific embodiments, the first connecting component may also be the limiting slide 11 and the positioning pin 22, in which case the second connecting component is the limiting slider 21 adapted to the limiting slide 11 and the positioning pin hole 12 adapted to the positioning pin 22. The third connecting component may be the positioning column 31 and the limiting block 42, in which case the fourth connecting component is the positioning hole 41 adapted to the positioning column 31 and the limiting slot 32 adapted to the limiting block 42.

[0031] In this embodiment, the limiting groove 32 and the limiting slide 11 are square grooves, and correspondingly, the limiting block 42 and the limiting slide 21 are square blocks. In other embodiments, the limiting groove 32 can also be a V-shaped groove, a U-shaped groove, etc., and this embodiment does not limit this.

[0032] In this embodiment, the LED box 100 includes a first side 10 and a second side (not shown) relative to each other, and a third side 30 and a fourth side (not shown) connecting the first side 10 and the second side. The first side 10 and the second side extend in a vertical direction, and the third side 30 and the fourth side extend in a horizontal direction. The first connecting member is arranged on the first side 10, the second connecting member is arranged on the second side, the third connecting member is arranged on the third side 30, and the fourth connecting member is arranged on the fourth side.

[0033] Taking one of the LED boxes 100 as a reference, let's assume that LED box 100 is box A, the LED box 100 to the left of box A is box B, the LED box 100 to the right of box A is box C, the LED box 100 above box A is box D, and the LED box 100 below box A is box E. Box A can then be connected to the second connector of box B via a first connector, to the first connector of box C via a second connector, to the fourth connector of box D via a third connector, and to the third connector of box E via a fourth connector. Alternatively, box A can be connected to the first connector of box B via a second connector, to the second connector of box C via a first connector, to the third connector of box D via a fourth connector, and to the fourth connector of box E via a third connector. It is understood that the first side 10 and the second side can also extend horizontally, while the third side 30 and the fourth side can extend vertically. At this time, the first connecting member and the second connecting member are located at the top or bottom of the LED box 100 , and the third connecting member and the fourth connecting member are located at the left or right side of the LED box 100 .

[0034] Preferably, Figure 4 and Figure 5 As shown, there are two positioning posts 31, and the two positioning posts 31 are symmetrically arranged on both sides of the third side 30. There are two limiting slides 11, and the two limiting slides 11 are respectively arranged at the top edge and bottom edge of the first side 10. There are two limiting sliders 21, and the two limiting sliders 21 are respectively arranged at the top edge and bottom edge of the second side. There are also two limiting grooves 32, and the two limiting grooves 32 are respectively arranged at the two end edges of the third side 30. There are two limiting blocks 42, and the two limiting blocks 42 are respectively arranged at the two end edges of the fourth side. By limiting the two ends at the same time, the two adjacent LED boxes 100 can be aligned more accurately. In addition, the positioning pin hole 12 is set in the middle of the first side 10, and the positioning pin 22 is set in the middle of the second side.

[0035] In other specific embodiments, the top edge of the first side 10 may be provided with a limiting groove 11 and the bottom edge with a limiting slider 21; the top edge of the second side may be provided with a limiting slider 21 and the bottom edge with a limiting groove 11. Similarly, the left edge of the third side 30 may be provided with a limiting groove 32 and the right edge with a limiting block 42; the left edge of the fourth side may be provided with a limiting block 42 and the right edge with a limiting groove 32. The left edge of the third side 30 may be provided with a positioning post 31 and the right edge with a positioning hole 41; the left edge of the fourth side may be provided with a positioning hole 41 and the right edge with a positioning post 31.

[0036] When the spliced LED boxes 100 of the embodiment of the present invention are spliced, the first connecting piece and the second connecting piece are connected in cooperation, and the third connecting piece and the fourth connecting piece are connected in cooperation, thereby ensuring precise positioning between the boxes.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
