However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Reference Figures 1 to 6 A splicing LCD display screen with a waterproof mechanism includes a display screen body 1; wherein the display screen body 1 is the main body of the liquid crystal display screen, and multiple display screens are spliced ​​together.

[0029] And, the positioning component 2 includes a first fixing member 21 and a second fixing member 22 disposed on the lower end face of the display body 1; wherein, the first fixing member 21 and the second fixing member 22 together provide dual locking power for splicing the display.

[0030] The first fixing member 21 includes a fixing block 211 fixedly connected to one side of the end face of the display body 1, an insertion plate 213 fixedly connected to the other side of the end face of the display body 1, and an external connecting block 215 disposed on the outer wall of the fixing block 211. The bottom part of the fixing block 211 is hollowed out to allow the insertion plate 213 to be inserted. The end face of the external connecting block 215 needs to be adapted to the fixing block 211 and the insertion plate 213 to ensure that the external connecting block 215 can be stably moved into the fixing block 211.

[0031] Furthermore, the second fixing member 22 includes an insertion block 222 disposed on the outside of the insertion plate 213, a first clamping plate 224 disposed on the outside of the fixing block 211, and a second clamping plate 225 disposed on the end face of the first clamping plate 224. The insertion block 222 is disc-shaped, one end of the second clamping plate 225 is protruding, and one end of the first clamping plate 224 is concave, so that the first clamping plate 224 and the second clamping plate 225 are in partial contact.

[0032] Specifically, the first fixing member 21 also includes an inner cavity 212 formed on the outer wall of the fixing block 211. The end face of the insertion plate 213 near the outer connecting block 215 is designed with an inclination, and the end face of the outer connecting block 215 near the insertion plate 213 is designed with an inclination that matches the end face of the insertion plate 213. The inner cavity 212 is used to install the outer connecting cylinder 214 and the inner support rod 219, while the sides of the insertion plate 213 and the outer connecting block 215 are designed with an inclination, thereby ensuring the stability of the insertion of the insertion plate 213 through the inclination design.

[0033] Furthermore, the inner wall of the inner cavity 212 is threadedly connected to an outer cylinder 214, and the outer wall of the outer cylinder 214 is provided with an inner groove 218. The outer wall of the outer block 215 is rotatably connected to a rotating disc 216. The outer cylinder 214 has a polygonal inner groove 218 inside, thereby ensuring the stable rotation of the outer cylinder 214.

[0034] Reference Figures 3-6 The end face of the rotating disc 216 is slidably connected to an inner connecting rod 217 that is adapted to the inner groove 218, and the upper end of the outer connecting block 215 is adapted to the inner cavity 212. The inner connecting rod 217 is used to engage with the inner groove 218, driving the outer connecting cylinder 214 to rotate synchronously, and the upper part of the outer connecting block 215 can gradually move along the inner cavity 212.

[0035] Specifically, an inner support rod 219 is slidably connected to the inner wall of the inner cavity 212, and a first spring 2110 is fixedly installed on the outer wall of the inner support rod 219. The end of the first spring 2110 is fixedly connected to the inner wall of the fixing block 211. The inner support rod 219 can be designed in two sets, which, together with the first spring 2110, allow the inner support rod 219 to move synchronously with the outer block 215.

[0036] Furthermore, the second fixing member 22 also includes a first fixing plate 221 fixedly connected to the end face of the insertion plate 213 and a second fixing plate 223 fixedly connected to the inner wall of the fixing block 211. The insertion block 222 is fixedly connected to the outer wall of the fixing block 211, and a connecting rod 226 is fixedly connected to the end face of the second fixing plate 223. The first fixing plate 221 and the second fixing plate 223 provide an installation platform for the insertion block 222 and the clamping plate.

[0037] Reference Figures 1-6The second fixing plate 223 has a first clamping plate 224 and a second clamping plate 225 inside. One end of the second clamping plate 225 extends into the interior of the first clamping plate 224, and the connecting rod 226 passes through the first clamping plate 224 and the second clamping plate 225. There is a certain gap between the first clamping plate 224 and the second clamping plate 225, so as to ensure that the insertion block 222 can be inserted between the first clamping plate 224 and the second clamping plate 225.

[0038] Specifically, an outer plate 227 is connected to the end faces of the first clamping plate 224 and the second clamping plate 225. A second spring 228 is fixedly connected to the outer wall of the outer plate 227, and the end of the second spring 228 is fixedly connected to the outer wall of the second fixing plate 223. The two ends of the second spring 228 are connected to the outer plate 227 and the second fixing plate 223 respectively, and the elastic force of the second spring 228 can be used to reset the first clamping plate 224 and the second clamping plate 225.

[0039] Furthermore, a waterproof component 3 is provided on the outer side of the display screen body 1. The waterproof component 3 includes a groove 31 formed on the end face of the display screen body 1, and a waterproof adhesive strip 32 is installed on the inner wall of the groove 31. The waterproof component 3 is composed of the groove 31 and the waterproof adhesive strip 32. When the display screens are spliced, the adhesive strip is compressed, and its internal hollow structure generates a strong rebound force, tightly filling the gaps and forming a physical barrier to achieve a waterproof effect.

[0040] Working principle: When splicing LCD displays, adjacent displays are gradually brought closer together. The insertion plate 213 on one side of the display body 1 is inserted into the fixing block 211. At this time, the rotating disc 216 is manually rotated, and the rotating disc 216 is rotatably connected to the outer connecting block 215. Since the inner connecting rod 217 is inserted into the inner groove 218, the rotation of the rotating disc 216 drives the rotation of the outer connecting cylinder 214, which in turn causes the outer connecting cylinder 214 to move threadedly inside the inner cavity 212. Finally, the outer connecting block 215 gradually moves closer to the fixing block 211. 1. During the movement of the outer block 215, its upper end is gradually inserted into the inner cavity 212. The end face of the outer block 215 is used to gradually control the inner support rod 219 to move inward, while squeezing the first spring 2110. When the end face of the outer block 215 contacts the end face of the insertion plate 213, the rotating screw disk 216 is stopped. At this time, the stability of the position of each component is ensured by the threaded connection between the outer cylinder 214 and the fixed block 211. The inclined surface of the outer block 215 is used to position the insertion plate 213, ensuring the stability of the splicing of the two sets of display screens.

[0041] When the insertion plate 213 moves to the predetermined position, it drives the first fixing plate 221 and the insertion block 222 to move to the inside of the fixing block 211. The end face of the insertion block 222 presses the gap between the first clamping plate 224 and the second clamping plate 225. At this time, the outer plate 227 moves towards the side closer to the second fixing plate 223 by the elastic force of the second spring 228, thereby opening the first clamping plate 224 and the second clamping plate 225, allowing the insertion block 222 to be inserted into the inside of the two clamping plates. At the same time, the outer plate 227 is no longer compressed, and the two clamping plates are reset by the elastic force of the second spring 228. The ends of the first clamping plate 224 and the second clamping plate 225 are stuck inside the insertion block 222, realizing the connection between the first fixing plate 221 and the second fixing plate 223, thereby further ensuring the stability of the splicing of the two display screen bodies 1. After the splicing of the display screen is completed, the gap between the two sets of display screen bodies 1 can be filled by the waterproof adhesive strip 32, so that the device has a certain waterproof effect.

[0042] It should be noted that when a single display screen is not spliced, the external block 215 needs to be moved to the outside to ensure that the insertion plate 213 can be stably inserted into the inside of the fixing block 211.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
