Description

Technical Field

[0001] This utility model belongs to the field of display device technology, specifically relating to a digital display screen suitable for physical exhibitions. Background Technology

[0002] Digital display installations at trade shows are devices that use digital technology to electronically display products, services, or information. These devices aim to enhance the display effect at trade shows or events, attract the attention of visitors, and convey information through digital means.

[0003] However, existing display devices of this type generally have a significant drawback: the height of their display screens is usually fixed. When there are many visitors at the booth, especially in large physical exhibitions, visitors at a distance may not be able to see the content on the screen at all due to obstructed views or insufficient screen height, greatly reducing the effectiveness of information delivery and the visitor's participation experience. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a digital display screen suitable for physical exhibitions to solve the problems in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a digital display screen suitable for physical exhibitions, including a display screen, a mounting base, a base, and a support frame; the mounting base is provided with an electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to the display screen; the base is provided with a rotating seat, and the mounting base is rotatably connected to the rotating seat through a turntable; the support frame is detachably installed on the base through a locking block.

[0006] Preferably, a connecting block is fixed to the back of the display screen, and the telescopic end of the electric telescopic rod is fixedly connected to the display screen through the connecting block; the use of a dedicated connecting block on the back enhances the connection stability between the display screen and the telescopic mechanism and avoids screen shaking caused by frequent lifting and lowering operations.

[0007] Preferably, the mounting base has upright plates on both sides, and the inner side of the upright plates has a sliding groove. The display screen has sliders on both sides, and the sliders are slidably connected in the sliding grooves. The cooperation design between the inner sliding groove of the upright plate and the slider on the side of the display screen provides vertical guidance during electric extension and retraction, effectively preventing the screen from tilting when it is raised or lowered, and ensuring that the height adjustment process is stable and accurate.

[0008] Preferably, the card block has a card slot with the same width as the base. The bottom surface of the base is provided with a threaded post. The bottom of the card slot has a through hole for the threaded post to pass through. A locking nut is threaded onto the threaded post. The through-connection structure of the card slot and the threaded post of the base, together with the locking nut, enables quick assembly and disassembly of the support frame, while ensuring load stability through mechanical locking.

[0009] Preferably, the support frame is connected to casters with a self-locking structure; the casters with self-locking function allow the whole machine to move and position freely within the exhibition hall, and form a stable support after locking.

[0010] Preferably, the locking nut is a wing nut; the design of the wing nut allows the support frame to be tightened by hand without tools.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. Through the electric telescopic rod structure on the mounting base, the height of the display screen can be dynamically adjusted according to the density and position of the audience. Operators can easily raise the display screen to ensure that the audience in a far position can also clearly see the screen content, avoiding the problem of obstruction of sight. This not only optimizes the coverage of information display, but also enhances the audience's sense of participation and interactive experience. It is especially suitable for physical exhibition scenarios with high traffic, making the transmission of product and service information more efficient.

[0013] 2. The support frame is detachably mounted on the base via a locking mechanism. With the help of casters with a self-locking structure, the entire device can be easily moved, fixed, or disassembled. Attached Figure Description
