[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3The present invention provides an embodiment of an LCD display splicing and fixing device that enables split-screen display, comprising a splicing frame 1, a support foot 4 fixedly connected to the bottom of the splicing frame 1 to evenly distribute the weight of the entire device and the installed display screen, a secondary mounting plate 3 with multiple pre-drilled mounting holes fixedly connected inside the splicing frame 1, a fan 2 installed inside the splicing frame 1, which accelerates the air circulation inside the device when the fan 2 is working, and promptly removes the heat generated during the operation of the display screen, and a main mounting component 5 installed inside the splicing frame 1;

[0037] The main mounting component 5 includes a frame 51. Inside the frame 51, a slide rail 56 is provided along the height direction of the frame 51. The inner wall of the frame 51 has grooves 55 evenly distributed along the extension direction of the slide rail 56. A sliding strip 52 is slidably connected inside the slide rail 56. A vertical plate 53 is fixedly connected to the rear wall of the sliding strip 52. Holes 511 are evenly distributed at the four corners and center of the vertical plate 53. Internal threads are provided on the inner wall of the holes 511, facilitating the secure installation of the sleeve 510 onto the vertical plate 53 via threaded connection. The sleeve 510 is fixedly connected inside the holes 511, and a telescopic rod 59 is slidably connected inside the sleeve 510. The frame 51 in the main mounting component 5 is the basic load-bearing structure, and its outer wall is fixed inside the splicing frame 1, providing stable support for subsequent installation components. Workers can pre-assemble the LCD screen with the main mounting plate 54, move the sliding bar 52 behind the main mounting plate 54 up and down, and with the help of the elastic properties of the spring 57, external force causes the locking block 58 to retract. After the main mounting plate 54 is adjusted to the appropriate position, the spring 57 resets and pushes the locking block 58 into the slot 55, thus initially fixing the main mounting plate 54 to the frame 51 and ensuring the initial positioning of the screen within the frame 51.

[0038] Reference Figures 2-4Multiple sets of auxiliary mounting plates 3 are provided, and these sets of auxiliary mounting plates 3 are distributed around the perimeter of the splicing frame 1. The front end of the telescopic rod 59 is fixedly connected to the main mounting plate 54, which is made of rectangular plate adapted to the mounting surface of the display screen. The surface is provided with screw holes corresponding to the mounting holes of the display screen. The outer wall of the main mounting plate 54 is elastically connected to the locking block 58 by a spring 57. One end of the spring 57 is fixedly connected to the inside of the main mounting plate 54, and the other end of the spring 57 is fixedly connected to the rear wall of the locking block 58. The spring 57 can quickly reset and push the locking block 58 out, realizing the quick engagement of the locking block 58 with the slot 55. The sleeve 510 is provided with Multiple sets of sleeves 510 are arranged around the main mounting plate 54. The outer wall of the frame 51 is fixedly connected to the inside of the splicing frame 1. Two sets of main mounting plates 54 are arranged, mirror-distributed along the central axis of the frame 51. After snapping, the head of the snap-fit ​​block 58 is completely embedded in the snap-fit ​​groove 55. The movement of the snap-fit ​​block 58 is restricted by the side wall of the snap-fit ​​groove 55. The outer wall of the snap-fit ​​block 58 is snapped into the inside of the snap-fit ​​groove 55. A sleeve 510 is fixedly connected to the hole 511 on the outer wall of the upright plate 53. The telescopic rod 59 is slidably connected to the sleeve 510, and the front end of the telescopic rod 59 is fixedly connected to the main mounting plate 54. This structural design allows the main mounting plate 54 to be flexibly adjusted within the frame 51. The operator can push the main mounting plate 54 to drive the telescopic rod 59 to slide within the sleeve 510, while the sliding bar 52 moves along the slide rail 56, thereby adjusting the horizontal position of the main mounting plate 54 and thus precisely adjusting the splicing spacing and alignment of the display screen.

[0039] Working Principle: During use, a sleeve 510 is fixedly connected to the hole 511 on the outer wall of the upright plate 53. The telescopic rod 59 is slidably connected to the sleeve 510, and the front end of the telescopic rod 59 is fixedly connected to the main mounting plate 54. This structural design allows the main mounting plate 54 to be flexibly adjustable within the frame 51. By pushing the main mounting plate 54, the telescopic rod 59 can slide within the sleeve 510, while the sliding bar 52 moves along the slide rail 56, thereby adjusting the horizontal position of the main mounting plate 54. This allows for precise adjustment of the splicing spacing and alignment of the display screens, meeting the requirements for precise splicing between multiple display screens during split-screen display. Multiple sets of auxiliary mounting plates 3 distributed around the splicing frame 1 further assist in fixing the display screens or other related components, enhancing the structural stability of the device and providing multiple guarantees for the reliable implementation of the split-screen display function. The core fixing function is first achieved using the main mounting component 5. The frame 51 in the main mounting component 5 is the basic load-bearing structure, and its outer wall is fixed inside the splicing frame 1, providing stable support for subsequent installation components. Workers can pre-assemble the LCD screen with the main mounting plate 54, move the sliding bar 52 behind the main mounting plate 54 up and down, and with the help of the elastic properties of the spring 57, external force causes the locking block 58 to retract. After the main mounting plate 54 is adjusted to the appropriate position, the spring 57 resets and pushes the locking block 58 into the slot 55, thus initially fixing the main mounting plate 54 to the frame 51 and ensuring the initial positioning of the screen within the frame 51.
