Description

Technical Field

[0001] This utility model relates to the field of drug prevention publicity and education technology, and in particular to a publicity board. Background Technology

[0002] In drug prevention publicity and education, information boards are an important tool for disseminating drug prevention knowledge and enhancing public awareness of drug prevention. However, traditional drug prevention information boards often have some shortcomings.

[0003] On the one hand, the height of bulletin boards is often fixed and cannot be adjusted according to different display environments and usage needs. For example, in some spaces with high ceilings, fixed low bulletin boards cannot make full use of the space and the display effect is poor; while in some spaces with limited space, bulletin boards that are too high may not be able to be installed properly or may affect the viewing experience of the audience.

[0004] On the other hand, replacing flyers on traditional bulletin boards is a rather cumbersome process. The flyers are usually fixed inside the bulletin board, and replacing them requires disassembling multiple parts, which is not only time-consuming and labor-intensive, but also prone to damaging the equipment during disassembly and installation, affecting its normal operation. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing anti-drug propaganda bulletin boards, which are often fixed in height and cannot be adjusted according to different display environments and usage needs, and whose operation is cumbersome when changing propaganda pages. Therefore, this utility model proposes a new type of propaganda bulletin board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bulletin board includes a bulletin board with an opening on one side, a transparent plate snapped into the inside of the bulletin board, and fixing screws threaded through both sides of the bulletin board. One end of each fixing screw extends into the interior of the transparent plate and is used to fix the transparent plate. It also includes two symmetrically arranged fixed side plates, which are located on both sides of the bulletin board. A vertical hole is provided on one side of each fixed side plate, and a connecting component for connecting the fixed side plate and the bulletin board is provided inside the vertical hole. The fixed side plate has a cavity inside, and one of the cavities is equipped with an adjustment component for adjusting the height of the bulletin board. Both sides of the bottom of the bulletin board are provided with clearance holes, and the interior of the clearance holes is provided with disassembly components for disassembling the bulletin board and fixing the side panels.

[0007] In one possible design, the connecting assembly includes a sliding plate I slidably connected inside the vertical hole, a connecting hole being formed on one inner wall of the vertical hole for connecting the vertical hole and the cavity, a connecting block being fixedly connected to one side of the sliding plate I, the connecting block slidingly passing through the connecting hole, and a sliding plate II being fixedly connected to one side of the connecting block, the sliding plate II being slidably connected inside the cavity.

[0008] In one possible design, the adjustment assembly includes a lead screw rotatably connected between the inner walls of the top and bottom of the cavity. The lead screw is threaded through a sliding plate II. A bevel gear I is fixedly sleeved on the outer wall of the lead screw. A rotating shaft rotatably passes through one side of the fixed side plate. A bevel gear II, meshing with bevel gear I, is fixedly connected to one end of the rotating shaft. A handwheel is fixedly installed at one end of the rotating shaft. Two symmetrically arranged triangular plates are fixedly connected to the inner wall of the bottom of the vertical hole.

[0009] In one possible design, two symmetrically arranged L-shaped inserts are slidably connected to one inner wall of the sliding plate I. A rectangular slider is fixedly connected to one bottom side of the L-shaped inserts, and a common compression spring is provided between the two L-shaped inserts.

[0010] In one possible design, the disassembly assembly includes a rectangular groove I formed on the inner wall of one side of the clearance hole. The bottom of the bulletin board has a bottom notch located below and connected to the rectangular groove I. Side slots are formed on both inner walls of the rectangular groove I. A connected rectangular groove II is formed on one inner wall of the bottom notch. The same L-shaped sliding plate is slidably connected between the two inner walls of the bottom notch. Two symmetrically arranged L-shaped sliding grooves are formed on the top of the L-shaped sliding plate. The L-shaped sliding grooves are used in conjunction with rectangular sliders. The L-shaped sliding plate is used in conjunction with the rectangular groove II. The side slots are used in conjunction with L-shaped inserts.

[0011] In one possible design, a support base is fixedly installed at the bottom of the fixed side plate.

[0012] In this application, during use, by rotating the handwheel, the handwheel drives the rotating shaft to rotate, the rotating shaft drives the No. 2 bevel gear to rotate, the No. 2 bevel gear drives the No. 1 bevel gear to rotate, the No. 1 bevel gear drives the lead screw to rotate, the lead screw drives the No. 2 sliding plate to move up and down, the No. 2 sliding plate drives the connecting block and the No. 1 sliding plate to move up and down. Since the L-shaped insert plate is inserted into the side slot and the No. 1 rectangular slot, the L-shaped sliding plate blocks the L-shaped insert plate from below. At this time, the L-shaped insert plate can drive the entire bulletin board to move up and down, thereby adjusting the height of the bulletin board to adapt to different environments. When it is necessary to disassemble the bulletin board and transparent panel, the bulletin board can be lowered to its lowest point. At this time, the inclined surface of the triangular plate abuts against the L-shaped insert, thereby bringing the two L-shaped inserts together. The compression spring is squeezed, and the two ends of the L-shaped insert retract from the inside of the side slot. The rectangular slider at the bottom of the L-shaped insert moves from the horizontal slot of the L-shaped slide to the vertical slot. At this time, the braking state of the L-shaped slide can be released, and the L-shaped slide can be pushed horizontally. The L-shaped slide moves from the inside of the bottom notch to the inside of the No. II rectangular slot, and is no longer located below the L-shaped insert. The bulletin board is then moved upward as a whole. After the bulletin board is moved out, the transparent panel can be disassembled by unscrewing the fixing screws to facilitate the replacement of the internal advertising pages.

[0013] Beneficial effects: By adjusting the design of the components and utilizing the cooperation of handwheels, rotating shafts, bevel gears, and lead screws, the height of the bulletin board can be easily adjusted, allowing it to adapt to display environments of different heights, meet diverse display needs, and improve its applicability and flexibility.

[0014] The modular design makes disassembling the bulletin board and transparent panel simple and quick. When it's time to replace the advertisement, simply follow the specific steps to quickly disassemble the bulletin board and transparent panel, saving time and labor costs and improving work efficiency.

[0015] The connecting components ensure a stable connection between the bulletin board and the fixed side panel. The combined use of the L-shaped insert and L-shaped sliding plate ensures the stability of the bulletin board during height adjustment and display, preventing it from shaking or falling off, thus improving safety and reliability.

[0016] Adopting a modular design concept, the various components are relatively independent yet work together, facilitating production, transportation, installation, and maintenance. When a component is damaged, it can be replaced individually, reducing maintenance costs and complexity. Attached Figure Description

[0019] 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.

[0020] In one embodiment: Refer to Figure 1-7 A type of bulletin board, mainly composed of bulletin board 3, fixed side plate 2, connecting components, adjusting components, disassembly components and support base 1.

[0021] The bulletin board 3 has an opening on one side, through which a transparent panel 4 is attached. Threaded fixing screws 20 pass through both sides of the bulletin board 3, with one end of each screw threaded into the transparent panel 4 for securing it. Two fixed side panels 2 are symmetrically positioned on either side of the bulletin board 3. A vertical hole 6 is formed on one side of each fixed side panel 2, housing a connecting component for connecting the fixed side panel 2 and the bulletin board 3. A cavity 13 is formed inside each fixed side panel 2, with an adjustment component inside one cavity for adjusting the height of the bulletin board 3. Clearance holes 21 are formed on both sides of the bottom of the bulletin board 3, housing a disassembly component for disassembling the bulletin board 3 and the fixed side panels 2. A support base 1 is fixedly mounted at the bottom of the fixed side panels 2, providing stable support for the entire device. The support base 1 is equipped with braked casters; sandbags can be placed on the support base 1 to increase stability in windy conditions.

[0022] In the connecting assembly, sliding plate I 8 is slidably connected inside the vertical hole 6. A connecting hole 7 is opened on the inner wall of one side of the vertical hole 6 to connect the vertical hole 6 and the cavity 13. A connecting block 16 is fixedly connected to one side of sliding plate I 8. The connecting block 16 slides through the connecting hole 7. Sliding plate II 15 is fixedly connected to one side of the connecting block 16. Sliding plate II 15 is slidably connected inside the cavity 13.

[0023] When adjusting the components, rotating handwheel 5 causes shaft 12 to rotate, which in turn drives bevel gear II 11. Bevel gear II 11 then drives bevel gear I 10, which in turn drives lead screw 14. Lead screw 14 can also be a threaded rod. Additionally, a bellows-shaped protective cover (not shown in the figure) is installed inside vertical hole 6 to protect lead screw 14. Since lead screw 14 is threaded through sliding plate II 15, its rotation causes sliding plate II 15 to move up and down. Sliding plate II 15, through connecting block 16, causes sliding plate I 8 to move up and down. Furthermore, because L-shaped insert 19 is inserted into side slot 23 and rectangular slot I 25, and L-shaped sliding plate 22 blocks L-shaped insert 19 from below, sliding plate I 8 can move up and down via L-shaped insert 19, thus adjusting the height of the bulletin board 3 to adapt to different display environments.

[0024] This application can be used in the field of drug prevention publicity and education, or in other fields applicable to this application.

[0025] In another embodiment: Reference Figure 1-7 A type of information board, used in the field of drug prevention publicity and education, has the following components for disassembly: Two symmetrically arranged L-shaped inserts 19 are slidably connected to the inner wall of one side of the sliding plate 8 (I). A rectangular slider 18 is fixedly connected to the bottom side of each L-shaped insert 19. A compression spring 17 is provided between the two L-shaped inserts 19. When it is necessary to disassemble the information board 3 and the transparent plate 4, the information board 3 is lowered to its lowest point. At this time, the inclined surface of the triangular plate 9 abuts against the L-shaped inserts 19. Under the action of the inclined surface of the triangular plate 9, the two L-shaped inserts 19 move towards the middle, the compression spring 17 is compressed, and the two ends of the L-shaped inserts 19 retract from the side slots 23. The rectangular slider 18 at the bottom of the L-shaped insert 19 moves from the horizontal slot of the L-shaped slide 27 to the vertical slot, releasing the braking state of the L-shaped slide plate 22. At this time, the L-shaped slide plate 22 can be pushed laterally, moving from the bottom notch 24 into the rectangular slot 26 (II), no longer located below the L-shaped inserts 19. Move the entire bulletin board 3 upwards. After the bulletin board 3 is moved out, the transparent panel 4 can be disassembled by unscrewing the fixing screw 20, making it easy to replace the internal advertising pages.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
