Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 As shown, a foldable stand is used to support and limit the writing display board in teaching or work. This stand adopts a foldable design, replacing the traditional welded and inconveniently stored stand, allowing it to be folded and stored, taking up little space when not in use. The specific structural design of the stand includes a first movable beam 1 and a second movable beam 2, which are foldable and parallel to each other via a movable structure. The movable structure is connected to a lifting structure for adjusting the height of the movable structure. In use, the distance between the first and second movable beams 1 and 2 is adjusted, and the writing display board is placed on the first and second movable beams 1 and 2 for "temporary limiting and fixing." Then, the height of the display board is adjusted by controlling the lifting structure, making it easy to display the content written on the display board. When not in use, the display board is removed from the first and second movable beams 1 and 2 by folding and storing them, and the lifting structure and movable structure used for lifting are disassembled and removed for easy storage.

[0024] Furthermore, in the embodiment, the movable structure of the arrangement includes a first scissor connecting rod 11 and a second scissor connecting rod 21. The first scissor connecting rod 11 and the second scissor connecting rod 21 are rotatably connected at their middle portions via a pivot. One end of the first scissor connecting rod 11 is hinged to one end sidewall of the first movable beam 1, and the other end of the first scissor connecting rod 11 is slidably disposed with one side arm of the second movable beam 2 near the first movable beam 1. One end of the second scissor connecting rod 21 is hinged to one end sidewall of the second movable beam 2, and the other end of the second scissor connecting rod 21 is slidably disposed with one side arm of the first movable beam 1 near the second movable beam 2. To enable the first movable beam 1 and the second movable beam 2 to be foldably connected via this "scissor" structure, a second sliding connecting seat is slidably connected to the arm of the second movable beam 2 near the first movable beam 1. The end of the first scissor connecting rod 11 near the second movable beam 2 is hinged to the second sliding connecting seat via a hinged seat. Similarly, a first sliding connecting seat is slidably connected to the arm of the first movable beam 1 near the second movable beam 2, and the end of the second scissor connecting rod 21 near the first movable beam 1 is hinged to the first sliding connecting seat via a hinged seat. Furthermore, the pivot at the middle of the first scissor connecting rod 11 and the second scissor connecting rod 21 is bolted to the lifting structure for limiting. The bolts control the "tightness" of the first scissor connecting rod 11 and the second scissor connecting rod 21, thereby "limiting" the position of the first movable beam 1 and the second movable beam 2 after unfolding. This facilitates the placement of a display panel on the first movable beam 1 and the second movable beam 2, which is achievable with existing technology and is not described in detail here.

[0025] After adjusting the positions of the first movable beam 1 and the second movable beam 2, the display board is placed on the first movable beam 1 and the second movable beam 2. In order to achieve the stability of the display board, a first sliding block 12 is slidably connected to one side of the first movable beam 1. A first limiting block for limiting the display board is connected to the first sliding block 12. The first sliding block 12 is limited and connected to the first movable beam 1 by bolts. A first baffle is connected to the end of the first movable beam 1 away from the first limiting block. The first sliding block 12 slides to clamp and limit the display board placed between the first sliding block 12 and the first limiting block. Since the second movable beam 2 has the same structure as the first movable beam 1 for limiting the display panel, a second sliding block 22 is slidably connected to one side of the second movable beam 2. A second limiting block for limiting the display panel is connected to the second sliding block 22. The second sliding block 22 is limited and connected to the second movable beam 2 by bolts. A second baffle is connected to the end of the second movable beam 2 away from the second limiting block. The second sliding block 22 slides to clamp and limit the display panel placed between the second sliding block 22 and the second limiting block. In the embodiment, by placing one side of the display panel between the first sliding block 12 and the first limiting block, and placing the other side of the display panel between the second sliding block 22 and the second limiting block, and then sliding the first sliding block 12 and the second sliding block 22 respectively, so that the other side of the display panel abuts against the first limiting block and the second limiting block, and then limiting and fixing the first sliding block 12 and the second sliding block 22 respectively with bolts, the display panel is fixed and limited on the first movable beam 1 and the second movable beam 2.

[0026] Furthermore, the height of the display board is adjusted appropriately using the lifting structure to facilitate viewing of its contents. This lifting structure includes a first telescopic rod 4 and a hollow second telescopic rod 5. One end of the first telescopic rod 4 is movably inserted into the hollow cavity of the second telescopic rod 5. The other end of the first telescopic rod 4 is detachably connected to a connecting block 6. The end of the connecting block 6 away from the first telescopic rod 4 is connected to a support rod 61 via a ball joint. The end of the support rod 61 away from the connecting block 6 is detachably connected to a connector 3. A limiting connecting rod (a bolt used to limit the connection between the first scissor connecting rod 11 and the second scissor connecting rod 21) movably passes through the connector 3. The end of the limiting connecting rod near the pivot used to connect the first scissor connecting rod 11 and the second scissor connecting rod 21 is limited to the pivot. The end of the second telescopic rod 5 away from the first telescopic rod 4 is connected to a support base 51 for supporting and stabilizing the second telescopic rod 5. A limiting bolt for limiting the first telescopic rod 4 movably passes through the second telescopic rod 5. Furthermore, the end of the connecting block 6 away from the first scissor connecting rod 11 is hinged to a support crossbar 62 via a hinge seat. A support slider is slidably connected to the support crossbar 62. The support slider is connected to a hinge rod 63 via a hinge seat. The end of the hinge rod 63 away from the support slider is hinged to a support hoop 64 via a hinge seat. The support hoop 64 is connected to the support rod 62. This design increases the contact area with the ground through the support base 51, stabilizing the bracket and the display panel placed on it. The height of the display panel can be adjusted by the relative height of the first telescopic rod 4 and the second telescopic rod 5. When it is necessary to adjust the "tilt angle" of the display panel, the support crossbar 62 is tightened to the hinge seat with bolts to fix the support crossbar 62. Then, by adjusting the position of the support slider on the support crossbar 62, the sliding of the support slider drives the hinge rod 63 to "move," which in turn drives the support rod 62 connected by the support hoop 64 to rotate around the connecting block 6 through the ball joint structure, thereby adjusting the "relative tilt" position of the display panel to achieve the purpose of use.

[0027] Furthermore, when the bracket is not needed, the display board can be removed from it, and the various detachable connecting structures of the bracket can be loosened to form a single structural component. The first movable beam 1 and the second movable beam 2 can then be folded and stored in a designated location for reassembly when needed. This bracket is used in teaching or work to support and limit the display board. Its foldable design allows for storage when the display board is not in use, minimizing its space requirements and reducing the risk of accidental collisions.

[0028] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the embodiments described above. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
