Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and in particular to a mounting structure, an LED video light bar and a light bar module. Background Art

[0002] LED video light strips have the advantages of long life, rich colors, good waterproof performance, and program control. They are widely used in indoor and outdoor decoration such as building outlines, billboards, and overpasses. Multiple LED video light strips form a light strip module, which can also be used in LED display screens to display signals, play dynamic graphics, etc.

[0003] The LED video light bar includes a light bar box, a light board and a mask. In the prior art, the light board is usually fixed to the light bar box by screws. However, with the improvement of people's display requirements, the LED video light bar begins to develop in a narrower direction. This fixing method is not only inconvenient for disassembly and assembly, but also can no longer be applied to the increasingly narrow LED video light bars. At the same time, the mask of the LED video light bar is usually provided with a slot on the inner side of the side wall of the light bar box. During installation, the mask needs to be inserted into the slot from one end of the light bar box. The light bar mask is relatively long, so the mask is easily damaged during plugging and unplugging. At the same time, in order to prevent the mask from sliding after being inserted into the slot, it is also necessary to fix it with screws, which further increases the complexity of the mask installation.

On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0049] Specific embodiment description section.

[0050] Embodiment 1:

[0051] Reference Figures 1 to 7 This embodiment proposes an LED video light bar, which includes a light board 11, a light box 12, a mask 13 and a mounting structure, wherein the mounting structure includes a light board fixing buckle 14 and a mask pin 15.

[0052] See also Figure 4 The inner sides of the two side walls of the lamp box 12 are provided with a boss 121 and a fixing buckle slot 122 , and the boss 121 is located below the fixing buckle slot 122 .

[0053] See also Figure 3 and Figure 5 The lamp panel fixing buckle 14 includes a pressing plate 141 , elastic clamping bones 142 are provided on both sides of the pressing plate 141 , and clamping blocks 146 are provided at the ends of the elastic clamping bones 142 .

[0055] In practical applications, the number of the elastic clamping bones 142 can be set according to actual needs. For example, an elastic clamping bone is set on each side of the pressing plate 141. Figure 5 As shown, two elastic clips may also be provided on both sides of the pressing plate 141 .

[0056] For some possible solutions, please continue to see Figure 3 and Figure 5 The elastic clamping bone 142 can be designed to be curved upward, one end of which is fixed on the pressing plate 141, and the other end is fixed with a clamping block 146.

[0057] See also Figure 7 In a to c, during installation, the lamp board 11 is placed on the boss 121. When the lamp board fixing buckle 14 is pressed downward, the inclined surface of the block 146 first contacts the side wall of the lamp box 12, making it easier to push the block 146 into the fixing buckle slot 122. At this time, the pressure plate 141 is on the lamp board 11, and the upper end surface of the block 146 cooperates with the top plane in the slot to prevent the block 146 from falling out of the fixing buckle slot 122. During disassembly, the lamp board fixing buckle 14 is pulled upward, the upper end surface of the block 146 is subjected to force, and the elastic clamping bone 142 is deformed, causing the upper end surface of the block 146 to tilt, thereby falling out of the fixing buckle slot 122.

[0058] In practical applications, the lamp board fixing buckle 14 can be pulled out from the lamp box 11 using the staple fixing buckle 144 . If there is no staple fixing buckle 144 , a protrusion or notch that is easy to operate can also be set on the pressure plate 141 to facilitate the removal of the lamp board fixing buckle 14 .

At this time, a positioning structure 143 can be provided on the back of the pressure plate 141 corresponding to the positioning holes 11, and a through hole 145 is provided on the positioning structure 143 along the center axis.

[0060] In practical applications, a through hole 145 may be provided on the pressure plate 141, and the positioning structure 143 may include at least two arc-shaped positioning blocks arranged around the through hole; or the positioning structure 143 may be directly designed as a positioning column, and a positioning column through hole is provided along its central axis and connected to the through hole 145.

[0061] The positioning hole and the positioning structure are provided to prevent the lamp board fixing buckle 14 from moving in the fixing buckle slot 122 .

[0062] The through hole 145 is provided to facilitate the glue filling of the lamp box and the lamp board.

[0063] In practical applications, see Figure 2 The lamp board 11 includes a PCB board 112 and an LED lamp 114 fixed on the PCB board 112 and electrically connected thereto, and a positioning hole 111 is provided on the PCB board 112 .

[0064] Please continue reading Figures 1 to 5 A stepped hole 131 is provided on the top of the mask 13; a staple fixing buckle 144 is provided on the front of the pressing plate 141; a nail cap 151 matching with the stepped hole 131 is provided on the top of the mask staple 15, and a clamping head 152 matching with the staple fixing buckle 144 is provided on the bottom.

[0065] See also Figure 3 as well as Figure 7 d to e, when installing the mask 13, place the two sides of the mask 13 on the top end surfaces of the two side walls of the lamp box 12, the clamp head 152 of the mask staple 15 passes through the stepped hole 131 and cooperates with the staple fixing buckle 144, and the nail cap 151 of the mask staple 15 cooperates with the stepped hole 131.

[0066] For practical applications, please refer to Figure 5 The number of the staple fixing buckles 144 can be at least two, which are evenly distributed around the through hole 145 on the pressing plate 141 , and the buckling direction of the staple fixing opening 144 is toward the through hole 145 .

[0067] In practical applications, in order to facilitate the removal of the nail cap 151 , a certain gap may be reserved between the stepped hole 131 and the nail cap 151 , or a notch may be provided on the nail cap 151 .

[0068] In practical applications, please refer to Figure 2 and Figure 3 In order to further increase the firmness of fixing the mask 13 , mask buckles 132 may be provided on both sides of the mask 13 , and the mask buckles 132 may cooperate with the fixing buckle slots 122 on the side walls of the lamp box 12 .

[0069] The LED video light bar of the present embodiment adopts a light board fixing buckle to fix the light board in the light box. The light board fixing buckle is fixed to the elastic clips on both sides of the pressure plate, and a clamping block is set at the end of the elastic clip. It is only necessary to set a fixing buckle slot and a boss on the inner side of the two side walls of the light box, so that the light board can be fixed in the light box by using the light board fixing buckle. It is not only convenient to disassemble, but also because no mounting holes are required on the boss and the light board, the width of the light board can be reduced to at least 5 to 6 mm, and the boss can also be set shorter, which is more conducive to the wiring of the light board circuit board; and the mask pins are matched with the pin fixing buckles on the light board fixing buckles to fix the mask on the box body. It is not only convenient to disassemble, but also avoids damage to the mask.
