[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] A folding display stand, the structure is as follows Figure 1-Figure 2As shown, it includes two groups of support frames, each group of the support frames includes a first support rod 1 and a second support rod 2, the top end of the first support rod 1 and the top end of the second support rod 2 are rotatably connected through a hinge shaft, the first support rod 1 and the second support rod 2 are respectively rotatably mounted with a first support rod 3 and a second support rod 4, the free ends of the first support rod 3 and the second support rod 4 are rotatably connected through a hinge shaft, the first support rod 1 and the second support rod 2 are both provided with a slide groove 9 on the opposite sides, and a slider 10 is installed in the slide groove 9, and the two groups of the support frames are connected by two A group of scissor-fork mechanisms are connected, and the scissor-fork mechanisms include a first connecting rod 7 and a second connecting rod 8. The middle parts of the first connecting rod 7 and the second connecting rod 8 are rotatably connected via a hinge shaft, the upper ends of the first connecting rod 7 and the second connecting rod 8 are respectively rotatably connected to the upper ends of the two groups of first support rods 1 via a hinge shaft, and the lower ends of the first connecting rod 7 and the second connecting rod 8 are respectively rotatably connected to the sliders 10 at the lower ends of the two groups of first support rods 1 via a hinge shaft. The way in which another group of the scissor-fork mechanisms are connected to the two groups of second support rods 2 is the same as the way in which the previous group of scissor-fork mechanisms are connected to the first support rod 1.

[0024] When the device is in the folded state and needs to be opened, since the top ends of the first support rod 1 and the second support rod 2 are connected by a hinge shaft, first, the two groups of first support rods 1 are pulled to move the bottom ends of the first support rods 1 away from the bottom ends of the second support rods 2, until the first support rod 3 and the second support rod 4 connected between the first support rod 1 and the second support rod 2 are completely in a parallel state from a partially folded state, and the top ends of the first support rod 1 and the second support rod 2 reach the maximum distance, and when the bottom ends of the first support rod 1 and the second support rod 2 are in contact with the ground, a triangular structure can be formed, and the stability is improved;

[0025] Then, the two groups of first support rods 1 are pulled toward each other to separate the two first support rods 1. When the two first support rods 1 are separated, the two second support rods 2 are separated together, and the scissor mechanism is opened from the folded state. When the scissor mechanism is opened, the upper ends of the first connecting rod 7 and the second connecting rod 8 rotate under the action of the hinge shaft, and the lower ends of the first connecting rod 7 and the second connecting rod 8 rotate under the action of the hinge shaft, which will drive the slider 10 to move upward in the slide groove 9 until it moves to the top of the slide groove 9. At this time, the operator can paste the promotional poster or advertising paper between the two first support rods 1 or the two second support rods 2. The whole process is simple to operate, and there is no need to disassemble and assemble the device, etc., which greatly reduces the difficulty of installation and improves the efficiency of installation.

[0026] When the device needs to be folded, it is only necessary to fold all the first support rods 1 and the second support rods 2 to achieve the folding effect. Since the bottom ends of the first connecting rod 7 and the second connecting rod 8 in the device move up and down in the slide groove 9 through the slider 10, the first connecting rod 7 and the second connecting rod 8 can be prevented from extending out of the main body of the device, thereby preventing the operator from being stabbed when the device is folded. In addition, the use of the slide groove 9 and the slider 10 can ensure smoothness when the device is folded.

[0027] A first limiter is provided on the hinge shaft connecting the first support rod 3 and the second support rod 4, and a second limiter is provided on the hinge shaft connecting the middle parts of the first connecting rod 7 and the second connecting rod 8.

[0028] The first limiter can limit the relative rotation between the first support rod 3 and the second support rod 4, which can effectively prevent the first support rod 3 and the second support rod 4 from bending from a horizontal state when the device is subjected to an external force, thereby increasing the risk of the device tipping over. The first limiter keeps the first support rod 3 and the second support rod 4 in a horizontal state, and forms a stable triangular structure with the first support rod 1 and the second support rod 2, thereby ensuring the improvement of the overall stability of the device.

[0029] Similarly, the second limiter between the first connecting rod 7 and the second connecting rod 8 can prevent the two groups of support frames from getting close to each other when subjected to external force. It is also through the second limiter that two triangular structures are formed to prevent the two groups of support frames from getting close to each other and prevent the slider 10 from sliding in the slide groove 9, thereby further ensuring the stability of the device.

[0030] The bottom ends of the first support rod 1 and the second support rod 2 have chamfered structures, and the bottom ends of the first support rod 1 and the second support rod 2 are provided with anti-slip layers.

[0031] When the device is fully supported, the chamfered structure can cooperate with the anti-slip layer to increase the contact area with the ground, prevent the device from sliding under external force, and avoid the device from hitting other equipment and causing damage to other equipment.

[0032] The whole device is made of aluminum alloy, which is strong and durable, light and easy to carry.

[0033] Embodiment 2

[0034] On the basis of the first embodiment, a reel 12 is installed on one of the first support rods 1 through a connecting block 11, a roll cloth is arranged in the reel 12 through a torsion spring, a buckle 5 is arranged at the free end of the roll cloth, and a block 6 adapted to the buckle 5 is arranged on the other first support rod 1. A through slot is provided on the buckle 5, the block 6 is an L-shaped structure, and the through slot is adapted to the L-shaped block 6. The roll cloth is made of a transparent material, and there is an interlayer in the middle of the roll cloth.

[0035] When the device is fully opened and it is necessary to post advertising paper or propaganda posters, the operator can pull the buckle 5, the reel 12 rotates, and the rolled cloth is pulled out from the reel 12. By buckling the buckle 5 on the clamping block 6, the rolled cloth can be prevented from being pulled back into the reel 12 under the action of the torsion spring. Since the rolled cloth is made of transparent material and has an interlayer inside, the operator can directly insert the advertising paper or propaganda poster into the interlayer, avoiding the use of products such as tape or double-sided tape, which makes it difficult to clean up later. In addition, compared with the use of tape or double-sided tape for adhesion, direct insertion can be completed faster and avoids wasting the operator's physical strength.

[0036] The above-mentioned roll cloth is not only transparent, but also has a certain degree of waterproofness, which can prevent accidental water stains on advertising paper or promotional posters, greatly improve the posting time of advertising paper and promotional posters, avoid replacing new posters with the same content due to stains in the middle, reduce the labor intensity of operators, and increase the posting life of advertising paper and promotional posters.

[0037] Embodiment 3

[0038] Based on the first embodiment, one of the second support rods 2 is provided with a magic adhesive tape.

[0039] When the device is moved manually or transported by vehicle in a folded state, the operator is also required to tie the device firmly to prevent the device from falling apart during movement. By wrapping the two sets of first support rods 1 and second support rods 2 with Velcro, and then sticking them on the Velcro, the efficiency and effect of tying can be effectively improved, and the situation that the device falls apart due to movement, resulting in damage to the device, can be avoided, thereby indirectly improving the service life of the device.

[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
