Description

Technical Field

[0001] The utility model relates to the technical field of exhibition hall broadcasting, and in particular to an exhibition hall splicing screen fixing device with good fixing effect. Background Art

[0002] An exhibition hall is generally called an exhibition venue. It is an activity venue used for displaying goods, conference exchanges, information dissemination, economic trade, etc. In order to better display the goods in the exhibition hall, display screens will be used for information display to attract people's attention. The display screens used now are mostly spliced ​​display screens.

[0003] The Chinese patent publication number is CN218327008U, a multi-screen splicing adjustment device for exhibition hall broadcasting, the technical solution provided by the patent document is: including a base, an adjustment rod and a fixed frame, two groups of adjustment rods are fixed on one side of the base, and two groups of fixed frames are movably set on one side of the adjustment rod, a rotating rod is installed inside the adjustment rod, and a motor is installed at one end of one group of rotating rods, a cross bar is fixed on one side of the base, and an adjustment component is installed on one side of the cross bar. The utility model solves the problem of inconvenient angle adjustment of the splicing screen, and the rotating rod is driven by the motor to rotate, so as to adjust the distance between the splicing screens, instead of manual adjustment, saving manpower, and can be remotely operated. The angle of the splicing screen on one side of the fixed frame can be adjusted by the electric telescopic rod, and the two groups of "eight"-shaped electric telescopic rods can adjust the angle of the splicing screen, so as to achieve a better display effect and display it to customers on both sides.

[0004] In order to solve the problem that the existing device can only adjust the spliced ​​screen manually, and the angle of the spliced ​​screen is difficult to change, and the angles of the base, the fixing rod and the adjusting rod need to be changed manually, which is time-consuming and labor-intensive, the existing technology adopts the settings of a motor, an adjustment component and a cross bar to solve the problem of inconvenient angle adjustment of the spliced ​​screen. The motor drives the rotating rod to rotate, thereby adjusting the distance between the spliced ​​screens, replacing the manual adjustment method, saving manpower for processing. However, when the clamping component is away from the spliced ​​screen, the spliced ​​screen will suddenly fall off the surface of the display stand, resulting in a poor fixing effect.
