Based on the embodiments of 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.

[0021] See also Figure 1-4The utility model provides a technical solution: a seamlessly spliced ​​splicing screen, comprising an installation frame 1, a display screen body 2 on the installation frame 1, an installation slot 3 on the side of the installation frame 1, a plug-in board 4 inserted into the installation slot 3, and a splicing screen 5. A fixing block 6 is symmetrically arranged on one side of the back of the installation frame 1, and a fixing seat 10 is symmetrically fixed on one side of the back of the installation frame 1 away from the fixing block 6. The fixing seat 10 is arranged correspondingly to the fixing block 6. A locking rod 7 is fixed on one end of the fixing block 6 away from the fixing seat 10. The side wall of the fixing seat 10 penetrates through the opening A through slot 11 is provided for the locking rod 7 to pass through, a slot 12 is provided on the side wall of the locking rod 7 located in the through slot 11, a locking block slot 14 is provided on the inner wall of the through slot 11, a locking block 13 for being inserted into the slot 12 is provided in the locking block slot 14, a control slot 16 is provided on the side wall of the locking block 13 located in the locking block slot 14, a pressure rod slot 17 is provided on the inner wall of the locking block slot 14 opposite to the control slot 16 and passes through the top of the fixing seat 10, and a pressure rod 18 is provided in the pressure rod slot 17 for acting with the control slot 16 to make the locking block 13 slide out of the slot 12.

[0022] Specifically, a fixing plate 8 is symmetrically fixed to the side wall of the fixing block 6, and the fixing plate 8 is fixedly connected to the installation frame 1 by screws. The fixing block 6 can be removed from the installation frame 1 by the screws on the fixing plate 8 to avoid the locking rod 7 on the edge of the installation frame 1 affecting the appearance.

[0023] Specifically, a locking block spring 15 is fixedly arranged in the locking block groove 14, and the locking block spring 15 is fixedly connected to the locking block 13. The locking block 13 is located at one end outside the locking block groove 14 and the side close to the fixing seat 10 is an inclined surface, which is convenient for splicing the display screen. When the two display screen bodies 2 are spliced, the plug plate 4 is first placed in the mounting groove 3 on the two adjacent mounting frames 1 (this is the prior art of the comparative document), and the locking rod 7 on one mounting frame 1 is passed through the through groove 11 on the fixing seat 10. The inclined surface of the locking block 13 is subjected to force so that the locking block 13 compresses the locking block spring 15 and slides into the locking block groove 14, and the locking rod 7 continues to Continue to slide in the through slot 11 until the plug board 4 abuts against the inner walls of the two installation slots 3. At this time, the locking block 13 is opposite to the card slot 12. Under the elastic force of the locking block spring 15, the locking block 13 is snapped into the card slot 12 to limit the locking rod 7, thereby completing the splicing of the two display screen bodies 2. The operation is convenient. The inner wall of the locking block slot 14 is symmetrically provided with limiting slots 23. A limiting block 24 fixedly connected to the side wall of the locking block 13 is slidingly provided in the limiting slot 23. Through the setting of the limiting slot 23 and the limiting block 24, it is prevented that the limiting block 24 slides out of the limiting slot 23 too much and affects the locking rod 7 passing through the through slot 11.

[0024] Specifically, one end of the control groove 16 that abuts against the pressure rod 18 is an inclined surface, and the other end of the pressure rod 18 that abuts against the control groove 16 is an arc surface. Pressing the pressure rod 18 applies force to the inclined surface of the control groove 16, so that the locking block 13 is forced to slide out of the card slot 12 and slide into the locking block slot 14, thereby causing the locking rod 7 to lose its limit and the display screen body 2 to be disassembled.

[0025] Specifically, return grooves 20 are symmetrically provided on the inner wall of the pressure rod groove 17, and a return spring 21 is fixedly provided on the inner wall of the return groove 20 near the locking block groove 14. The return spring 21 is fixedly connected to a return block 22 which is slidably connected to the return groove 20 and fixedly connected to the side wall of the pressure rod 18. Under the elastic force of the return spring 21, the pressure rod 18 is kept in the pressure rod groove 17 to prevent the pressure rod 18 from affecting the sliding of the locking block 13. After the pressure rod 18 is pressed, the pressure rod 18 is reset under the elastic force of the return spring 21. A pressure plate 19 is fixedly connected between the two pressure rods 18. Pressing the pressure plate 19 can press the two pressure rods 18 at the same time, thereby facilitating the splitting of the two display screen bodies 2.

[0026] Specifically, a connecting plate 9 is fixedly connected between the two locking rods 7 , and the connecting plate 9 can improve the stability of the locking rods 7 . An empty groove is provided on the connecting plate 9 to reduce the weight of the locking rods 7 .

[0027] A specific application example of this embodiment is:

[0028] When the device is in use, when two display screen bodies 2 are to be spliced, the plug-in board 4 is first placed in the mounting grooves 3 on two adjacent mounting frames 1 (this is the prior art of the comparative document), and the locking rod 7 on one mounting frame 1 is passed through the through groove 11 on the fixing seat 10. The inclined surface of the locking block 13 is subjected to force so that the locking block 13 compresses the locking block spring 15 and slides into the locking block groove 14. The locking rod 7 continues to slide in the through groove 11 until the plug-in board 4 abuts against the inner walls of the two mounting grooves 3. At this time, the locking block 13 is directly opposite to the card slot 12. Under the elastic force of the locking block spring 15, the locking block 13 is snapped into the card slot 12 to limit the locking rod 7, thereby completing the splicing of the two display screen bodies 2. The operation is convenient. The other display screens can be spliced ​​by analogy. The fixing block 6 can be removed from the installation frame 1 by the screws on the fixing plate 8 to prevent the locking rod 7 on the edge of the installation frame 1 from affecting the appearance. When disassembling, the pressing plate 19 is pressed, and the pressing plate 19 presses the pressing rod 18 and drives the return block 22 to compress the return spring 21. The pressing rod 18 acts on the inclined surface of the control groove 16, so that the locking block 13 is forced to slide out of the card slot 12 and slide into the locking block slot 14, so that the locking rod 7 loses its limit, and the locking rod 7 can be pulled out of the through slot 11, and the display screen body 2 is disassembled. Under the elastic force of the return spring 21, the pressing rod 18 is reset to facilitate the next installation, and the operation is convenient.
