Description

A display device for conference and exhibition

Technical Field

The utility model relates to the technical field of display devices, in particular to a display device for conferences and exhibitions.

Background Art

Display stands are also known as product display stands, promotion stands, portable display equipment and information stands. Display stands can make products stand out in front of the public, thereby increasing the advertising effect of products. They are beautiful in style, noble and elegant, and have good decorative effects. They are widely used in conference rooms, exhibition halls and other places. When companies hold meetings, they often need to use display stands. Existing conference display stands are generally equipped with dedicated demonstration whiteboards. The organizers of the meeting often use markers to write and demonstrate on the demonstration whiteboard according to the content of the meeting, so that the main content of the meeting can be more clearly received by the participants. However, the existing display stands can generally only be equipped with one specification of demonstration whiteboard. Sometimes the writing area of the demonstration whiteboard cannot meet the writing requirements of the conference organizers, and the writing effect of the demonstration whiteboard is inevitably greatly reduced in long-term use. However, the existing display stands are not convenient for replacing the demonstration whiteboard.

After searching, the Chinese patent with announcement number: CN217013267U discloses a special display stand for conferences and exhibitions. The driving device provided can adjust the two cross blocks on the left and right sides to be relatively far away or close, so that the vertical rods on the left and right sides are relatively far away or close. By adjusting the spacing between the vertical rods on the left and right sides to a suitable distance, it can match the demonstration whiteboards of different widths, so that the demonstration whiteboard can be fixed by means of a card plate, a screw rod and a fixer. The vertical adjustment device provided can drive the two fixing blocks on the same vertical rod to be relatively close or far away, so that the fixing device can match the demonstration whiteboards of different heights. By adjusting the driving device and the vertical adjustment device in a coordinated manner, the fixing device can fix the demonstration whiteboards of different widths and heights, and the fixing device can fix the demonstration whiteboard by turning the dial to drive the screw rod, which is easy to use.

When this patent is actually used, there are the following defects:

In this patent, when replacing and fixing the demonstration whiteboard, it is necessary to first adjust the driving device so that the fixing device can adapt to the width of the demonstration whiteboard of corresponding specifications, and then use the vertical adjustment device to adjust the fixing device to adapt to the height of the demonstration whiteboard, which makes the operation of replacing the demonstration whiteboard more cumbersome, thereby reducing the efficiency of the display stand.

If the display whiteboard 18 needs to be installed and replaced, first, drag the display whiteboard 18 with one hand and pull the handle 17 with the other hand to adjust the width and height of the display device at the same time. When the handle 17 is pulled to the left, the handle 17 drives the movable plate 9 to move, and the movable plate 9 drives the gear 8 to rotate, and the gear 8 drives another movable plate 9 to move relative to each other. The movable plate 9 drives the second telescopic rod 15 to move, and the second telescopic rod 15 drives the square plate 12 to move, and the square plate 12 drives the first telescopic rod 11 to retract and extend, and the square plate 12 drives the fixed plate 13 to move and adjust the width of the display device and place the display whiteboard 18 on the fixed plate 13 for support. The first telescopic rod 11 supports the fixed plate 13. When the handle 17 is pulled downward, the handle 17 drives the movable plate 9 to move downward, and the movable plate 6 drives the shell 6 to move. The housing 6 moves downward, and the housing 6 drives the other movable plate 9 to move downward. The movable plate 6 squeezes and contracts the second telescopic plate 15 to adjust the height of the display device and squeezes and fixes the display whiteboard 18, so that the width of the display device can be adjusted left and right while the height of the display device can be adjusted up and down. Referring to the above steps, the handle 17 is pulled upward, and the handle 17 drives the fixed plate 13 to move upward to release the limit of the used display whiteboard 18 and replace it with a new display whiteboard 18. The handle 17 is pulled downward, and the handle 17 drives the fixed plate 13 to move downward to limit and fix the new display whiteboard 18, so that the effect of quickly clamping and replacing the used display whiteboard can be achieved, thereby preventing the situation that the replacement operation of the used display whiteboard is more cumbersome and reduces the use efficiency of the display device.
