[0023] Example 1

[0024] Please refer to the attached document. Figures 1-4This application provides a combined large-screen splicing structure, including a main support 1 and a secondary support 2. The main support 1 is provided with a vertical slide rail, and the secondary support 2 is provided with a vertical slide groove 4 that mates with the slide rail. The bottom of the slide rail can be inserted from the top of the slide groove. The secondary support 2 is horizontally positioned and is provided with locking bolts 21 that engage with the main support 1. The secondary support 2 is provided with a mounting base 6 for mounting a display screen. When installing the combined large screen, the main support 1 must first be installed and secured. Then, the display screen is installed onto the secondary support 2. This step can be completed on the ground, and the lower position of the secondary support 2 makes the installation process more convenient. After the display screen is installed, the slide groove on the secondary support 2 is aligned with the slide rail of the main support 1, and then the secondary support 2 is pushed upwards, allowing the secondary support 2 with the display screen to smoothly rise along the slide rail to the predetermined position of the main support 1. When the secondary support 2 reaches the designated position, it is securely locked using the locking bolts 21 to ensure the stability of the overall structure, thus completing the installation of the combined large screen. The secondary bracket 2 of this utility model is equipped with a mounting base 6, and the display screen can be fixed on the secondary bracket 2 through the mounting base 6, which facilitates the safe fixation of the display screen.

[0025] Specifically, the mounting base 6 includes multiple L-shaped mounting pieces 7, each comprising a horizontal piece and a vertical piece. The horizontal piece has a horizontal slot 8, and the vertical piece has a vertical slot 9. A first bolt 10 passes through the horizontal slot 8 and connects to the sub-support 2, while a second mounting bolt 11 passes through the vertical slot 9 and connects to the display screen. Due to the horizontal slot 8, the L-shaped mounting pieces 7 can be adjusted left and right to adjust the spacing between the display screens. Due to the vertical slot, the display screens can be adjusted forward and backward to ensure they are on the same horizontal plane. Combined with the vertical movement of the sub-support 2, it allows for three-dimensional adjustment, ensuring that all installed display screens are on the same plane.

[0026] Specifically, the back of the sub-support 2 is provided with a guide groove 12, and a slider 13 and a spring 14 are provided in the guide groove 12. The spring 14 pushes the slider 13 to move upward. The slider 13 is equipped with a friction wheel 15. One side of the friction wheel 15 contacts the main support 1, and the other side contacts the wedge block 16 fixed on the sub-support 2. The slider 13 can slide up and down along the guide groove 12. The bottom of the slider 13 is provided with a spring 14. Under the push of the spring 14, the slider 13 moves upward, thereby driving the friction wheel 15 to move upward. Both sides of the friction wheel 15 are in close contact with the main support 1 and the wedge block 16. When the sub-support 2 moves upward, the friction force on the friction wheel 15 is downward, causing the friction wheel 15 to move downward. At this time, the friction wheel 15 moves away from the wedge block 16, so the sub-support 2 can easily move upward. As the secondary support 2 moves downward, the friction wheel 15 experiences upward friction. At this time, the friction wheel 15 moves towards the wedge block 16, causing it to be clamped in the gap between the wedge block 16 and the main support 1, thus forming a self-locking structure to prevent the secondary support 2 from moving downward. This invention utilizes the cooperation of the friction wheel 15 and the wedge block 16 to initially fix the secondary support 2, facilitating its installation and adjustment. After the secondary support 2 is initially fixed, the locking bolt 21 is used to further secure it, improving stability.

[0027] Specifically, the main support 1 and the wedge block 16 are provided with an anti-slip structure 17 on the side that contacts the friction wheel 15. This increases friction, allowing the secondary support 2 to be fixed more stably.

[0028] Specifically, the slide rail is a T-shaped slide rail 18, the slide groove is a T-shaped slide groove 19, the sub-support 2 is provided with a threaded hole 20, and the locking bolt 21 is threadedly connected to the threaded hole 20. After the sub-support 2 is connected to the slide rail of the main support 1, the sub-support 2 can only slide up and down, preventing the sub-support 2 from moving back and forth and disengaging from the slide rail, thus improving stability.

[0029] Specifically, the locking bolt 21 is provided with an internal hexagonal groove 22. Tightening the locking bolt 21 through the internal hexagonal groove 22 can hide the locking bolt 21 from the front, improving its aesthetics.

[0030] Example 2

[0031] Please refer to the attached document. Figures 1-4 The difference between this embodiment and Embodiment 1 is that the main support 1 includes a fixed frame 23 and a base 24. The fixed frame 23 is mounted on the base 24, and the fixed frame 23 is provided with the slide rail. The base 24 is fixed to the ground, and the base 24 is then connected to the fixed frame 23. The base 24 provides a stable support effect, making it easy to install the combined large screen on the ground.

[0032] Specifically, the base 24 includes a column 25 and a support rod 26. The upper end of the column 25 is connected to the main support 1, and the support rod 26 is connected to the bottom of the column 25. The support rod 26 increases the support area and improves stability.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
