[0002] In order to promote Chinese calligraphy and painting culture and let people appreciate the charm of calligraphy and painting, some schools or art galleries will hold art exhibitions regularly. In the process of holding the exhibition, exhibition boards are needed. In order to facilitate transportation and carrying, the exhibition boards are usually folded.

[0003] At present, the entire structure of the existing folding display board is relatively simple. Therefore, when calligraphy and painting works need to be displayed, the framed paintings are only hung up through two sets of picture hooks. When the display board is accidentally bumped by some naughty children while playing, it is easy to cause the hanging paintings to shake or fall, which will pose a great safety hazard during the display. Therefore, we propose a folding display board to solve the above problem. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A foldable display board includes a foldable display board body 1, a rectangular groove 2 is provided inside the foldable display board body 1, and transparent plates 3 are symmetrically connected to the front and rear sides of the rectangular groove 2. There are multiple groups of foldable display board bodies 1, and the multiple groups of foldable display board bodies 1 are connected by hinges, so that the foldable display board bodies 1 can be folded with each other for easy transportation and storage. A movable plate 4 is engaged with the side where the transparent plates 3 are close to each other, and the left and right ends of the movable plate 4 are in contact with the inner wall of the rectangular groove 2. Since the transparent plate 3 is set to be transparent, it is easy to see the paintings placed in the rectangular groove 2. The top of the movable plate 4 is symmetrically connected to a connecting rod 5. Through the mutual cooperation between the movable plate 4 and the connecting rod 5, when the staff pulls up the connecting rod 5, the movable plate 4 and the painting can be driven to move up, so that the staff can take the painting out of the rectangular groove 2.

[0024] Further, see Figure 3 It can be seen that sliders 7 are symmetrically connected to both sides of the movable plate 4, and a slideway adapted to the sliders 7 is provided inside the folding display board body 1. When in use, the stable up and down movement of the movable plate 4 can be effectively guaranteed through the cooperation between the sliders 7 and the slideway.

[0025] Further, see Figure 1 and Figure 2 It can be known that the top end of the connecting rod 5 is connected through a sealing block 6, and the cross-sectional area of ​​the sealing block 6 is larger than the opening area of ​​the top end of the rectangular groove 2. When in use, the sealing block 6 with a larger cross-sectional area can cover the top end opening of the rectangular groove 2 to prevent dust and debris from entering the interior of the rectangular groove 2.

[0026] Further, see Figure 3 and Figure 4It can be known that a support plate 9 is engaged inside the rectangular groove 2, and insertion grooves adapted to the connecting rod 5 are opened at both ends of the support plate 9, a slot hole 10 is opened inside the support plate 9, and a rectangular block 11 is symmetrically engaged inside the slot hole 10, and a limiting rod 12 is connected to the side of the rectangular blocks 11 away from each other, and the limiting rod 12 passes through the inner wall of the support plate 9 and extends to the connecting rod 5, and positioning grooves adapted to the limiting rod 12 are opened equidistantly from top to bottom inside the connecting rod 5, and a spring 13 is sleeved on the outer side of the limiting rod 12, and One end of the spring 13 is connected to the rectangular block 11, and the other end of the rectangular block 11 is connected to the inner wall of the groove 10. The front of the rectangular block 11 is connected to a pull rod 14, and a slide groove compatible with the pull rod 14 is provided inside the support plate 9. When in use, the slide groove provided inside the support plate 9 can effectively ensure that the pull rod 14 drives the rectangular block 11 to move left and right, so as to effectively ensure that the limit rod 12 slides inside the groove 10, thereby effectively releasing the limit on the support plate 9, thereby realizing the adjustment of the height of the painting.

[0027] Further, see Figure 2 It can be known that the upper side of the support plate 9 is connected to the limiting plate 15, and the inner side of the limiting plate 15 is glued with a rubber pad. Through the mutual cooperation of the limiting plate 15 and the rubber pad, the reliability of placing the painting on the support plate 9 can be effectively guaranteed.

[0028] Further, see Figure 5 It can be known that the bottom end of the movable plate 4 is symmetrically connected with a positioning rod 8, and a card slot adapted to the positioning rod 8 is opened inside the folding display board body 1. The mortise and tenon connection between the movable plate 4 and the folding display board body 1 can effectively prevent the sealing block 6 from shifting during the covering process.

[0029] Further, see Figure 3 It can be seen that a groove is provided at the bottom end of the foldable display board body 1, and a ball is installed inside the groove. The setting of the ball can prevent the foldable display board body 1 from directly contacting and rubbing against the ground, so as to protect the bottom end of the foldable display board body 1.

[0030] Working principle: When the utility model is in use, the staff can first transfer the folding display board body 1 to a suitable position, and then pull up the sealing block 6, thereby driving the movable plate 4 and the supporting plate 9 to be lifted up as a whole through the connecting rod 5. At this time, the user can manually pull the two sets of pull rods 14 according to the height of the painting, so that it drives the two sets of limit rods 12 to approach each other, so that the limit rods 12 are pulled out from the inside of the connecting rod 5, and then the staff can push the supporting plate 9 up and down to a suitable height. After the adjustment is completed, the staff can stop pulling the pull rod 14, so that the limit rod 12 is reset by the elastic force of the spring 13, so that the limit rod 12 can be engaged. The corresponding positioning groove is opened inside the connecting rod 5, so as to fix the position of the support plate 9, and then the staff can place the calligraphy and painting works on the support plate 9. At this time, the staff can push down the sealing block 6, so that the movable plate 4 and the support plate 9 move down as a whole. After the positioning rod 8 connected to the bottom end of the movable plate 4 is inserted into the interior of the folding display board body 1, the sealing block 6 can cover the top opening of the rectangular groove 2 to achieve the sealing of the interior of the rectangular groove 2. After placing multiple groups of calligraphy and paintings into the interior of the folding display board body 1 in turn, the staff can rotate the folding display board body 1 to a suitable angle for display. The above is the entire working principle of the present utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
