[0021] 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.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a splicing LCD display screen; specifically, it consists of a display screen body 1 and a fixing frame 2. The fixing frame 2 has a cross-shaped structure and is fixed to the wall with screws. The display screen body 1 is then hung on the fixing frame 2, and the gaps between the display screen bodies 1 must be installed parallel to meet the installation requirements. This is existing known technology and will not be described in detail here. A sliding groove 5 is provided at the upper end of the crossbar of the fixing frame 2, and a support rod 6 is hung on the sliding groove 5 on the fixing frame 2. A hanging groove 7 is provided at the front end of the support rod 6. A connecting mechanism is fixed on the back side of the display screen body 1 and is matched with the hanging groove 7. A calibration mechanism is fixed in the middle of the fixing frame 2. The calibration mechanism is set through the splicing seam of the display screen body 1. The connecting mechanism can stably hang the display screen body 1 on the support rod 6. At the same time, the position of the support rod 6 on the sliding groove 5 varies depending on the size of the display screen body 1. The position of the support rod 6 on the sliding groove 5 is adjusted accordingly. At the same time, the calibration mechanism can facilitate the standardization of the position of the display screen body 1 during installation.

[0023] The connecting mechanism includes a fixing plate 14, which is fixed to the back side of the display screen body 1. A support frame 15 is fixed on the fixing plate 14. The support frame 15 is matched with the hanging groove 7. A limit block 16 is fixed in the middle of the support frame 15. The limit block 16 is matched with the recess of the support rod 6. The support frame 15 is inclined downward. After the support frame 15 is hung on the hanging groove 7, it forms an upward support, which plays a role in stabilizing and fixing the display screen body 1.

[0024] The calibration mechanism includes a fixed base 11, which is fixed in the middle of the fixed frame 2. A slot 12 is provided on the outer end face of the fixed base 11, and a calibration piece 13 is inserted into the slot 12. The calibration piece 13 is cross-shaped and can be used to calibrate the installation position of the four display screen bodies 1. The thickness of the calibration piece 13 is the minimum setting of the connection seam between the display screen bodies 1, which facilitates the installation and splicing of the display screen bodies 1.

[0025] The upper and lower ends of the support rod 6 are threaded with fixing buttons 8 at the middle position. The fixing buttons 8 pass through the support rod 6 and abut against the upper and lower ends of the fixing frame 2. A calibration hole 9 is provided at the middle position of the support rod 6. Correspondingly, a scale line 10 is provided on the outer end face of the crossbar of the fixing frame 2. The calibration hole 9 and the scale line 10 are matched and set to facilitate the adjustment and uniformity of the position of the support rod 6.

[0026] An installation groove 4 is provided at one end of the mounting bracket 2, and an installation block 3 is fixed at the other end. The installation block 3 and the installation groove 4 are matched and inserted into each other. When multiple display screen bodies 1 are installed, multiple mounting brackets 2 need to be installed. This facilitates the installation of the mounting brackets 2 and makes installation and docking easier.
