[0006] Furthermore, the magnetic component includes an iron sheet and a magnetic plate, and the mating surfaces of the two plates are respectively fitted with patches and magnetic plates, and the iron sheet and the magnetic plate are magnetically attracted to each other.

[0007] Furthermore, the inner walls of both side supports are connected to crossbars, which are staggered vertically. The bottom surface of one crossbar is connected to the top surface of the other crossbar, and the ends of the two crossbars are rotatably connected by a hinge axis.

[0008] Furthermore, the two crossbars are connected to an adjustment structure for adjusting the lifting and lowering of the partition plates. The adjustment structure includes a movable seat, which is slidably connected to the crossbar. A support rod is rotatably connected to the top of the movable seat. The end of the support rod away from the movable seat is rotatably connected to the bottom of the partition plate. The movable seats on the two crossbars are symmetrically arranged, and the partition plates are slidably connected to the side brackets.

[0009] Furthermore, a vertical groove is provided in the side support, and a slider is slidably connected in the vertical groove. The partition plate is rotatably connected to the slider.

[0010] Furthermore, one end of the movable seat is fixedly connected to an extension plate, a movable groove is provided in the crossbar, a threaded rod is slidably connected in the movable groove, and a threaded ring is threadedly connected to one end of the extension plate.

[0011] Furthermore, multiple limiting grooves are provided on both sides of the inner wall of the vertical slide groove, and a limiting strip corresponding to the limiting groove is fixedly connected to the outer wall of the slider.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a flip-up blackboard with adjustable function includes a flip-up blackboard 1, side supports 2 connected to both sides of the flip-up blackboard 1, and a movable support 4 connected to the bottom of the side supports 2. The flip-up blackboard 1 is divided into two sections along the center line. The outer walls of the two sections are rotatably connected to the corresponding side supports 2. A hinge 8 is fixedly installed between the two sections, and a magnetic suction element 10 is connected to the contact surface of the two sections.

[0023] like Figures 1 to 5 As shown, when the adjustable flip-top blackboard 1 is in normal writing mode, the two panels are horizontally unfolded, and the magnetic suction component 10 firmly attracts the two panels to ensure normal writing.

[0024] During transportation, the flip-up blackboard 1 can be bent with force, so that the two panels are folded under the action of the hinge 8, and at the same time, the two side supports 2 are also folded. The bottom of the movable support 4 is equipped with universal wheels with brakes, and one of the side supports 2 is set in a Z-shape near the end of the movable support 4. This setting can ensure that the two movable supports 4 on both sides will not obstruct each other after the two panels are folded.

[0025] By setting the flip-up blackboard 1 as two foldable panels, the originally long blackboard can be easily adjusted and folded, reducing its footprint and making it easier to transport and carry.

[0026] like Figure 3 As shown, the magnetic component 10 includes an iron sheet and a magnetic plate. The mating surfaces of the two plates are respectively fitted with a patch and a magnetic plate, and the iron sheet and the magnetic plate are magnetically attracted to each other.

[0027] Specifically, after the two boards are merged, the embedded patches and magnetic plates can smoothly ensure the stability of the merged boards, thus ensuring the stability of the blackboard during writing.

[0028] At the same time, when it is necessary to adjust and fold the two panels, the magnetic panels can be separated by external force, which makes the operation convenient.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the inner walls of both side supports 2 are connected to crossbars 5. The two crossbars 5 are staggered vertically. The bottom surface of one crossbar 5 is connected to the top surface of the other crossbar 5, and the ends of the two crossbars 5 are rotatably connected by a hinge 8.

[0030] Specifically, when the flip-up blackboard 1 is in use, one of the crossbars 5 overlaps with another crossbar 5, and their ends are rotatably connected by the axis of the hinge 8, so that the crossbars 5 can improve the stability of the two boards when they are unfolded and used.

[0031] like Figure 3 and Figure 5 As shown, the two crossbars 5 are connected to an adjustment structure for adjusting the lifting of the partition. The adjustment structure includes a movable seat 6, which is slidably connected to the crossbar 5. A support rod 7 is rotatably connected to the top of the movable seat 6. The end of the support rod 7 away from the movable seat 6 is rotatably connected to the bottom of the partition. The movable seats 6 on the two crossbars 5 are symmetrically arranged, and the partitions are slidably connected to the side bracket 2.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a vertical slide groove 21 is provided in the side support 2, and a slider 3 is slidably connected in the vertical slide groove 21. The partition plate is rotatably connected to the slider 3.

[0033] like Figure 5 As shown, one end of the movable seat 6 is fixedly connected to an extension plate 61, and a movable groove 51 is opened in the crossbar 5. A threaded rod 9 is slidably connected in the movable groove 51, and a threaded ring 91 is threadedly connected to the outer side of one end of the extension plate 61 through the threaded rod 9.

[0034] Specifically, to make the flip-up blackboard 1 more convenient to use, when users of different heights are writing, they can push the partition upwards, causing the sliders 3 at both ends of the partition to slide in the vertical groove 21. Then, the sliding seat 6 is slid, causing the extension plate 61 and the threaded rod 9 to slide in the horizontal bar 5 and the moving groove 51, while driving the support rod 7 to rotate, so that the support rod 7 supports the partition. Then, the threaded ring 91 can be rotated, and the position of the moving seat 6 is limited by friction, thereby limiting the height of the partition. The other partition can be operated in the same way.

[0035] Through the structure of slider 3 and vertical slide 21, the height of the flip-up blackboard 1 can be adjusted on the side support 2, making it suitable for users of different heights; by utilizing the cooperation of support rod 7, moving seat 6, threaded rod 9 and threaded ring 91, the height of the adjusted partition can be supported and limited, ensuring the stability of the partition after adjustment.

[0036] like Figure 5 As shown, multiple limiting grooves 22 are provided on both sides of the inner wall of the vertical slide groove 21, and a limiting strip 31 corresponding to the limiting groove 22 is fixedly connected to the outer wall of the slider 3.

[0037] Specifically, when the slider 3 slides in the vertical groove 21, the limiting strip 31 on the outside of the slider 3 will slide in the limiting groove 22. This setting ensures that the partition plate has a certain limiting resistance during the sliding process.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
