Referring to fig. 1-4, the present application provides an embodiment of a display screen splicing seat, which includes a mounting plate 1, a connecting plate 5, and an intermediate mechanism;

as shown in fig. 5, the mounting plate 1 is used for mounting display screens, when two or more display screens need to be spliced, each display screen needs to be positioned and fixed, and after the display screens are positioned and fixed, the smaller the gap between two adjacent display screens needs to be, the better the gap is, so that there is a certain requirement for positioning the display screens, and a carrier capable of supporting and fixing the display screens is needed.

When one display screen is connected with one carrier, the other position of the display screen needs to be connected with another carrier, and the other carrier needs to be connected with another display screen besides the display screen, so that the position of the carrier needs to have adjustability to ensure that the two display screens have small gaps after being connected, so that the positions of the carriers need to be moved to the positions of the display screens instead of the positions of the display screens, and if the positions of the carriers are fixed, the display screens can be passively connected with the carriers, and the gaps between the display screens cannot be ensured.

In this embodiment, the mounting plate 1 is a carrier for mounting a display screen, the connecting plate 5 is used for connecting to a fixture, it is to be noted that the fixture is an object other than the display screen splicing seat, and may be a steel pipe, a steel frame structure, a wall, etc., after the connecting plate 5 is connected to the fixture, the splicing seat provided in this embodiment is fixed, because the structure, type, and arrangement manner of the fixture are not fixed, when the connecting plate 5 is connected to the fixture, the position of the mounting plate 1 may not reach an intended effect and therefore needs to be adjusted, when splicing a plurality of display screens, this embodiment adopts a form commonly used by a plurality of splicing seats, the plurality of splicing seats are all fixed to the fixture through the connecting plate 5, although the connecting plate 5 is fixedly disposed, the position of the mounting plate 1 is adjustable, the intermediate mechanism is respectively connected to the mounting plate 1 and the connecting plate 5, the intermediate mechanism is used for adjusting the positions of the mounting plate 1 in a first direction, a second direction, and a third direction, and two pairs of the first direction, the second direction and the third direction are mutually perpendicular. The first direction, the second direction and the third direction are mutually perpendicular in pairs, that is, the first direction is simultaneously perpendicular to the second direction and the third direction, and the second direction and the third direction are mutually perpendicular, which is equivalent to the XYZ axis direction in the coordinate system. Therefore, the position of the mounting plate 1 in the embodiment can be adjusted in three directions, and the splicing requirement of the display screen is met.
