Description

Technical Field

[0001] The utility model relates to the technical field of display board fixing, in particular to a display board fixing device. Background Art

[0002] Display boards are a useful medium for displaying goods or artworks in daily life and are widely used in exhibition halls, museums and other places. Traditionally, display boards are fixed directly to the wall or displayed on display stands. However, these methods have the following drawbacks:

[0003] 1. Fixing the display board directly to the wall requires drilling holes in the wall, which is time-consuming and labor-intensive. In addition, the hole positions must be adapted to the size of the display board. If the hole positions do not match, the subsequent horizontal and stable installation of the display board cannot be guaranteed.

[0004] 2. When installing display panels directly on the wall for display, if they are fixed directly with screws, additional connectors need to be added to the outside of the display panel. This will result in the screws and connectors being exposed when the display panel is displayed, affecting the appearance. If they are hung by screws, although the display panel can be used to cover the screws, it cannot ensure the firmness and stability of the display panel and is very easy to fall off.

[0005] 3. Using display racks to display exhibition boards not only takes up space, but also the display rack structure is often relatively simple and can only be adapted to the installation of exhibition boards of certain sizes, so the scope of application is relatively small;

[0006] Therefore, there is an urgent need for a display board fixing device that can overcome the above-mentioned shortcomings. Utility Model Content

[0011] Furthermore, an expanded diameter section is provided in the middle of the rod body of the bidirectional screw rod.

[0012] Furthermore, the adjacent ends of the two bottom rods are each provided with a diameter-enlarging edge arranged around the bottom rod body.

[0013] Furthermore, a side baffle for limiting the lower edge of the display panel is provided on one side of the support plate close to the end of the bottom rod.

[0014] Furthermore, the driving mechanism B includes a screw and an expanding head. A screw hole is provided on the cross bar body, which penetrates the cross bar along the axial direction of the vertical bar. The screw penetrates the cross bar through the screw hole. A through hole is provided on the top bar body, which penetrates the top bar along the axial direction of the vertical bar. The upper end of the screw penetrates to the upper part of the top bar through the through hole. An expanding head is provided at the end of the screw located at the upper part of the top bar.

[0015] Furthermore, a sinking groove adapted to the enlarging head is provided on the rod body of the push rod, and a through hole is provided on the inner bottom surface of the sinking groove.

[0016] Furthermore, a screw groove is provided on the upper surface of the enlarging head.

[0019] Through the cooperation of the support plate and the pressure plate, the display board can be clamped and fixed simply and conveniently, which greatly improves the installation and fixing efficiency of the display board;

[0020] By driving the bottom bars with the driving mechanism A, the two bottom bars can be adaptively adjusted according to the width of the display board, thereby providing strong support for the subsequent bottom bar end support plates to safely and stably support the display board;

[0021] By setting the driving mechanism B to adjust the push rod, the push rod can be adaptively adjusted according to the width of the display board, thereby providing strong support for the subsequent pressing plate on the push rod to press and fix the display board;

[0022] By providing polygonal through holes and matching bottom bars, the bottom bars can be prevented from rotating during support or movement, providing strong support for the subsequent stable support of the display board.

[0023] By providing an expanded diameter edge at the end of the bottom rod, the bottom rod can be effectively limited and blocked to prevent it from separating from the vertical rod, thus ensuring the horizontal stability of the bottom rod;

[0024] The utility model can not only provide convenient and efficient fixed support for the display board, but also can be adaptively adjusted according to the size of the display board, which greatly facilitates the fixed display operation of the display board, reduces the workload of the staff, and alleviates the work difficulty of the staff.
