Technical Field

[0001] The utility model relates to the technical field of display boards, in particular to an adjustable display board. Background Art

[0002] Exhibition boards refer to display tools used to publish and display information. They are widely used in museums, science and technology museums, exhibitions and other fields. By placing them at the entrance and laying out instructions on the exhibition boards, visitors can easily understand the main content of the event, which has a good publicity and guidance effect. However, the existing exhibition board structure cannot adjust its own length. Therefore, some larger foam boards cannot be effectively fixed on the exhibition board surface. The only way is to customize the corresponding exhibition board racks, which increases the exhibition cost and is not conducive to use. Utility Model Content

[0005] The frame body has composite arms symmetrically provided on both sides of the frame body, the composite arms are connected to the frame body by a rotating shaft, and form a snap-fit positioning with the frame body when in a horizontal position, the composite arms are provided with a plurality of detachable mounting legs, and the composite arms can be extended in the length direction.

[0006] Preferably, a first card slot is symmetrically provided at the connection between the composite arm and the rotating shaft of the frame; a support plate is provided at the rear of the frame, and two second card slots are respectively provided on both sides of the support plate, and card blocks are installed in the second card slots.

[0007] Preferably, the composite arm includes a first arm body and a second arm body; one end of the first arm body is connected to the frame body by a rotating shaft, and the other end is slidably connected to the second arm body, and limiting grooves are respectively provided above and below the first arm body.

[0008] Preferably, the first arm is provided with a plurality of fixing holes.

[0009] Preferably, a hollow groove is provided in the middle of the second arm body, and one end of the hollow groove is open, and the width of the hollow groove is greater than the diameter of the fixing hole.

[0010] Preferably, a plurality of incomplete threaded holes are provided in the empty slot.

[0011] Preferably, a support seat is provided below the frame.

[0012] Preferably, the support seat is provided with an adjustment component connected to the frame.

[0013] Preferably, the adjustment assembly includes a first connecting rod and a sliding sleeve; one end of the first connecting rod is connected to the support seat by a rotating shaft, and the other end is slidably connected to the sliding sleeve, and a clamping column is provided at the end of the first connecting rod; the sliding sleeve is connected to the frame by a rotating shaft, and a locking groove is provided on the sliding sleeve that cooperates with the clamping column.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The frame as a whole can meet the requirements of fixing foam boards of conventional sizes. When the size changes, each composite arm can be rotated and unfolded respectively, and can continue to extend its own length, thus effectively adapting to the fixation of foam boards of different lengths and sizes. There is no need to re-order, which greatly saves the intermediate preparation time. The overall operation is simple and convenient, and has good applicability.

[0016] 2. After the composite arm is unfolded, the mounting feet can form multiple fixing points for the foam board, which is convenient for laying the foam board. The number of mounting feet can be adjusted as needed to ensure the reliability after fixation.
