[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2The utility model provides an embodiment: a spliced ​​liquid crystal display screen, including a splicing frame 1, a plurality of contact plates 2 are fixedly connected to the inner rear sides of the plurality of splicing frames 1, a hand-tightening bolt 3 is threadedly connected to the rear side of the contact plate 2, a liquid crystal display screen body 4 is slidably connected to the front side of the splicing frame 1, small fans 5 are arranged on the upper and lower sides of the inner wall of the splicing frame 1, a first air duct 6 is opened in the middle of the inner wall of the splicing frame 1, a plurality of air slots 7 are opened on the front side of the splicing frame 1, wire slots 8 are opened at the left and right ends of the front side of the splicing frame 1, second air ducts 9 are opened on the upper and lower sides of the inner wall of the splicing frame 1, a through wire channel 10 is opened in the middle of the splicing frame 1, and a quick-connect component is arranged on the left side of the splicing frame 1.

[0032] The LCD screen bodies 4 are placed one by one according to the reserved slots on the splicing frame 1, and the four rear corners can just touch the contact plate 2. The LCD screen body 4 is slidably connected to the front side of the contact plate 2. A plurality of hand-tightening bolts 3 penetrate the contact plate 2 and are threadedly connected to the four rear corners of the LCD screen body 4. The four rear corners of the LCD screen body 4 are connected and fixed by the hand-tightening bolts 3 to ensure the compactness of the splicing. After the fixation is completed, since there are many wire harnesses of the LCD screen body 4, they can all pass through the wire groove 8 into the through-line 10. Then, after connecting between multiple splicing frames 1, the lines are connected and arranged from the through-line 10. When a single LCD screen body 4 is damaged or needs maintenance, it is only necessary to disconnect the circuit connection from the through-line 10, and then the corresponding rear hand-tightening bolts 3 can be reversed to complete the quick removal.

[0033] The first air duct 6 is communicated with the second air duct 9, and the first air duct 6 and the second air duct 9 form an I-shaped cooling channel on the inner wall of the splicing frame 1. Multiple air slots 7 are communicated with the first air duct 6, and multiple air slots 7 are communicated with the second air duct 9. During daily use, in order to reduce overheating inside the LCD display body 4, multiple small fans 5 provided in the splicing frames 1 can be turned on in turn, and the internal heat can be discharged through the setting of multiple groups of first air ducts 6 and second air ducts 9, thereby increasing the service life of the LCD display body 4 and reducing maintenance costs.

[0034] Reference Figure 2-Figure 4 The quick-connect assembly includes a docking block 11, which is fixedly connected to the upper and lower ends of the left side of the splicing frame 1. The upper and lower ends of the rear end of the splicing frame 1 are fixedly connected to positioning blocks 12. The inner wall of the positioning block 12 is slidably connected to a pull rod 13. The middle part of the outer wall of the pull rod 13 is fixedly connected to a push plate 14, and a spring 15 is arranged on the rear side of the push plate 14.

[0035] When the four LCD screen bodies 4 are all fixed on the splicing frame 1, one splicing frame 1 can be placed on the right side of the other splicing frame 1, and the docking block 11 is slidably connected to the inner wall of the mounting groove 16, so that the docking block 11 can slide into the interior of the mounting groove 16, and then the pull rod 13 is pulled to drive the push plate 14 to compress the spring 15, so that the docking block 11 is completely stuck in the interior of the mounting groove 16, and after reaching the appropriate position, the pull rod 13 can be loosened, and the push plate 14 is slidably connected to the inner wall of the positioning block 12. Under the push of the spring 15 on the push plate 14, the pull rod 13 sequentially penetrates the positioning block 12 and the mounting groove 16 and is slidably connected to the inner wall of the docking block 11, and one side of the pull rod 13 will slide into the interior of the docking block 11, thereby completing the quick installation.

[0036] The spring 15 is arranged on the rear side of the inner wall of the positioning block 12 , and such a design can limit the position of the other side of the spring 15 .

[0037] Working principle: When installing the LCD screen for use, first place the LCD screen body 4 according to the reserved slots on the splicing frame 1 to ensure that the four corners of the rear side are in close contact with the contact plate 2. Then, use the hand-tightening bolts 3 to fix the four corners of the rear side of the LCD screen body 4 to ensure the compactness of the splicing. After the fixation is completed, since there are many wire harnesses on the LCD screen body 4, they can be uniformly guided into the through-line 10 through the wire groove 8. After connecting multiple splicing frames 1, the lines are connected and arranged from the through-line 10.

[0038] If a single LCD screen body 4 is damaged or needs maintenance, it is only necessary to disconnect the circuit connection in the through-line 10 and quickly disassemble it by reversing the hand-tightening bolts 3 on the corresponding rear side. When the four LCD screen bodies 4 are fixed on the splicing frame 1, one splicing frame 1 can be placed on the right side of another splicing frame 1, so that the docking block 11 slides into the installation groove 16. Then, pull the pull rod 13 to make the push plate 14 compress the spring 15 to ensure that the docking block 11 is completely stuck in the installation groove 16. When the appropriate position is reached, release the pull rod 13, and under the push of the spring 15, one side of the pull rod 13 will slide into the inside of the docking block 11, thereby completing the quick installation.

[0039] In daily use, in order to increase the service life of the LCD screen body 4 and reduce maintenance costs, the small fan 5 provided on the splicing frame 1 can be regularly turned on. By providing multiple sets of first air ducts 6 and second air ducts 9, the internal heat can be effectively discharged and the operating temperature of the display screen body can be reduced.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
