[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] This embodiment relates to a promotional display board, the overall structure of which is as follows: Figure 1-Figure 4 As shown, it includes a vertical frame 1, a folding arm 2, a display arm 3 and a display board 4. The vertical frame 1 is used to be placed on the work floor. One end of the folding arm 2 along the length direction is hinged to the top of the vertical frame 1 and can be folded to one side of the vertical frame 1. The display arm 3 is hinged to the folding arm 2 and can be folded to fit the folding arm 2. The display board 4 is detachably connected to the display arm 3 and printed with display content.

[0038] Reference Figure 1 and Figure 2 When the display board is in the display state, the folding arm 2 is unfolded to the top of the vertical frame 1 and extends upward, the display arm 3 is unfolded and perpendicular to the folding arm 2, and the display board 4 is connected to the display arm 3; when the display board is in the storage state, the display arm 3 is folded and attached to the folding arm 2, and the folding arm 2 is folded and attached to one side of the display frame, so that the overall length is shortened, the occupied space is reduced, and it is convenient for users to move and store it. The display board 4 can be an elastic board such as a plastic board, a foam board, a wooden board, etc., or it can be a flexible object such as paper, cloth, etc.

[0039] Specifically, in this embodiment, at least two folding arms 2 are provided, which are evenly distributed along the circumference of the top of the vertical frame 1. Multiple folding arms 2 are also equipped with display arms 3, which can increase the number of display boards 4 that can be exhibited and enrich the display content.

[0040] Reference Figure 1 and Figure 3 As an exemplary structure, in this embodiment, two folding arms 2 are provided, which are arranged on opposite sides of the top of the vertical frame 1; when the two folding arms 2 are rotated to the top of the vertical frame 1, magnets 21 are embedded on the side walls facing each other of the two folding arms 2, and the magnetic poles of the two magnets 21 are opposite.

[0041] The two folding arms 2 are symmetrically arranged at the top of the vertical frame 1, which can make the overall display board more stable when placed. When the two folding arms 2 are rotated to the top of the vertical frame 1, the two magnets 21 attract each other, so that the two folding arms 2 can remain in the unfolded state.

[0042] Specifically, in this embodiment, two display arms 3 are hinged on each folding arm 2 , and the hinges between the two display arms 3 and the folding arm 2 are located at opposite ends of the folding arm 2 .

[0043] When the display board is in the display state, the two display arms 3 on the same folding arm 2 are unfolded and located at different heights, so that the contents of the upper and lower display boards 4 can be displayed simultaneously.

[0044] As an exemplary structure, an opening is provided on the folding arm 2, so that the folding arm 2 forms a C-shaped structure. After the two display arms 3 are folded in sequence, they are completely located in the opening and do not protrude from the edge of the opening, so that the display board is relatively flat after being stored.

[0045] Reference Figure 2 and Figure 4As an exemplary structure, a hook 31 is provided on the display arm 3 whose hinge axis is far away from the hinged joint of the folding arm 2 and the vertical frame 1. That is, when the display board is in the unfolded state, of the two display arms 3 hinged on the same folding arm 2, the upper display arm 3 is provided with a hook 31, and the hook 31 is hinged to the display arm 3 and is used to hook the folding arm 2 to keep the display arm 3 in the unfolded state. A groove is provided on the display arm 3 at a position corresponding to the hook 31, and the hook 31 can be put into the groove when not in use.

[0046] As an exemplary structure, a clamping groove 32 is provided on the display arm 3. The clamping groove 32 is U-shaped and penetrates in a direction away from the hinge axis of the display arm 3. When the display board is in the display state, the openings of the clamping groove 32 are all downward. An elastic member 33 is connected to any one of the two opposite groove walls of the clamping groove 32. A pressure plate 34 is connected to the end of the elastic member 33 away from the groove wall. The pressure plate 34 is used to press the display board 4 and prevent the display board 4 from falling out of the clamping groove 32 through friction. The elastic member 33 can be any one of a spring, an elastic metal sheet or an elastic rubber sheet. In this embodiment, the elastic member 33 is a spring. Each pressure plate 34 is correspondingly provided with five springs, and each spring is evenly spaced. The side of the pressure plate 34 facing the display board 4 can be coated with an anti-slip coating to increase the friction between the display board 4 and the display board 4.

[0047] As an exemplary structure, an anti-skid pad 35 is provided on the groove wall opposite to the clamping groove 32 and the pressing plate 34. The anti-skid pad 35 is bonded to the groove wall of the clamping groove 32 and can be a rubber or plastic gasket. Under the action of the elastic member 33, the pressing plate 34 and the anti-skid pad 35 clamp the display board 4 together, which can improve the installation firmness of the display board 4.

[0048] Reference Figure 1 and Figure 2 As an exemplary structure, the lower part of the vertical frame 1 is hinged with a support leg 11, which is used to abut against the working ground and support and balance the vertical frame 1. The number of the support legs 11 is at least three, and each support leg 11 is evenly distributed along the circumference of the bottom end of the vertical frame 1. In this embodiment, the number of the support legs 11 is four, and the vertical frame 1 is a rectangular parallelepiped. The four support legs 11 are respectively arranged on the four side elevations of the vertical frame 1, which can support the vertical frame 1 more stably.

[0049] As an exemplary structure, a limiting member 12 is connected to the vertical frame 1, and the limiting member 12 is used to limit the maximum opening angle of the support legs 11, and each support leg 11 corresponds to a limiting member 12. In this embodiment, the limiting member 12 is an L-shaped plate, one end of which is fixedly connected to the vertical frame 1, and the other end is used to abut against the support leg 11. When the four support legs 11 are fully opened and erected on the working ground, the bottom end of the vertical frame 1 does not contact the working ground.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
