Whether it is spliced horizontally or vertically, it can meet different display requirements, so as to facilitate flexible splicing and use according to the venue where the video conference is held.

[0003] The existing liquid crystal display screens are mainly connected to each other by bolts and nuts. Although the connection firmness of adjacent liquid crystal display screens is ensured, since the bolts and nuts are installed separately, during the connection process, the staff needs to first insert the bolts into the connection holes, and then manually screw the nuts onto the bolts. Finally, a handle is used to tighten the bolts. At the same time, during disassembly, the bolts and nuts also need to be manually separated, which increases the complexity of the installation and disassembly of the bolt connectors, further reduces the splicing efficiency of the liquid crystal display screens, and during the installation and disassembly of adjacent liquid crystal display screens, due to the separate structure of the bolts and nuts, it is easy to cause the loss of bolt connection components, thereby reducing the reuse rate of the bolt connectors.

Moreover, the whole connecting component is integrally designed, so as to reduce the risk of loss of connecting parts during the installation and disassembly of adjacent liquid crystal display screens, thereby further increasing the reuse rate of the connecting component.

[0025] Please refer to Figure 4, in the telescopic assembly shown in the figure, a telescopic hole 801 is provided in the sliding block 402, the connecting block 403 is slidably connected to the telescopic hole 801, a spring 802 is fixedly connected to the bottom wall of the telescopic hole 801, and the other end of the spring 802 is connected to the connecting block 403;

[0026] It should be noted here that: through the setting of the telescopic assembly, it provides guidance and reset functions for the movement of the connecting block 403.

[0027] Please refer to Figure 3 , in the driving assembly shown in the figure, a driving rod 501 is rotatably connected to the connecting pipe 401, a threaded strip 502 is provided on the side wall of the driving rod 501, the sliding block 402 is threadedly connected to the threaded strip 502, one end of the driving rod 501 far from the sliding block 402 penetrates through the connecting pipe 401 and is fixedly connected with a driving disk 503, and the connecting pipe 401 is provided with a guiding assembly for guiding the movement of the sliding block 402;

[0028] It should be noted here that: through the setting of the driving assembly, it is convenient to make the sliding block 402 move in the connecting pipe 401.

[0029] Please refer to Figure 3 , in the guiding assembly shown in the figure, two symmetrically arranged guiding grooves 601 are provided on the inner wall of the connecting pipe 401, two guiding plates 602 are slidably connected to the two guiding grooves 601, and one end of the two guiding plates 602 opposite to each other is connected to the sliding block 402;

[0030] It should be noted here that: through the setting of the guiding assembly, it provides guiding and limiting functions for the movement of the sliding block 402.

[0031] Working principle: When it is necessary to use the display body 1 to hold a video conference, it is necessary to splice multiple display bodies 1. During the splicing process of two adjacent display bodies 1, first, the connecting edges of the two adjacent display bodies 1 are opposite to each other, and the connecting cylinders 3 on the back of the two adjacent display bodies 1 are aligned. Then, the connecting pipe 401 is inserted into the two opposite connecting cylinders 3;

[0032] After inserting the connecting pipe 401 into the connecting cylinder 3, by rotating the driving disk 503, the threaded bar 502 on the driving rod 501 is driven to rotate. Thus, under the threaded meshing transmission of the threaded bar 502 and the sliding block 402 and the guiding action of the guiding assembly, the sliding block 402 will be driven to move closer to the connecting cylinder 3. During the movement of the sliding block 402, when the connecting block 403 aligns with the through hole 404, under the elastic action of the telescopic assembly, the connecting block 403 will be pushed out of the connecting pipe 401. After the connecting block 403 is pushed out of the connecting pipe 401, the abutting assembly can be used to make the connecting block 403 abut against the side wall of the connecting cylinder 3. Thus, under the abutting action of the abutting assembly and the connecting block 403 on the adjacent connecting cylinder 3, the connection and fixation of the adjacent display body 1 are realized;

[0033] When the video conference ends and the display body 1 needs to be disassembled, by rotating the driving disk 503, using the threaded meshing transmission of the threaded bar 502 and the sliding block 402 and the guiding action of the guiding assembly, the sliding block 402 is made to move away from the connecting cylinder 3. During the movement of the sliding block 402 away from the connecting cylinder 3, when the connecting block 403 abuts against the through hole 404, under the mutual acting force of the inclined surface 405 and the guiding action of the telescopic assembly, the connecting block 403 will be pushed to contract into the connecting pipe 401. When the connecting block 403 is completely contracted into the connecting pipe 401, the connecting pipe 401 can be pulled out from the two opposite connecting cylinders 3. Thus, the connection limit between the adjacent two display bodies 1 is released. The operation is simple and the implementation is convenient. Thus, while ensuring the firm connection of the adjacent two display bodies 1, the convenience of connecting and fixing and disassembling the adjacent two display bodies 1 is improved. Thus, the splicing efficiency of the liquid crystal displays is further improved, and the whole connecting assembly is integrally designed. Thus, the risk of loss of connecting parts caused by the installation and disassembly of adjacent liquid crystal displays is reduced. Thus, the reuse rate of the connecting assembly is further increased.

[0034] Embodiment 2

[0035] Please refer to Figure 3 This embodiment further illustrates Embodiment 1. The connecting pipe 401 in the figure is provided with an abutting assembly for making the two connecting blocks 403 abut against the connecting cylinder 3. The abutting assembly includes a threaded groove 701 opened on the side wall of the connecting pipe 401, and a tightening ring 702 is threadedly connected to the threaded groove 701;

[0036] It should be noted here that: through the setting of the counteracting component, by means of the threaded meshing drive between the tightening ring 702 and the threaded groove 701, the tightening ring 702 slides on the side wall of the connecting pipe 401. When the tightening ring 702 abuts against the side wall of the connecting cylinder 3, it will drive the two connecting blocks 403 to abut against the opposite side wall of the connecting cylinder 3. Thus, under the tightening action of the tightening ring 702 and the connecting block 403, the connection and fixation of two adjacent display body 1 are realized.

[0037] Please refer to Figure 2 , a retaining ring 9 is fixedly connected to one end of the connecting pipe 401 close to the driving disc 503 in the figure;

[0038] It should be noted here that: through the setting of the retaining ring 9, it is used to limit the tightening ring 702 to prevent the tightening ring 702 from slipping off the side wall of the connecting pipe 401, thereby preventing the loss of the tightening ring 702.
