Technical Field

[0001] This utility model relates to the technical field of bulletin board installation, and in particular to a bulletin board structure that is easy to assemble and disassemble. Background Technology

[0002] Currently, bulletin boards are devices used for posting posters and other promotional materials. In related technologies, bulletin boards need to be installed on aluminum square tubes, and since bulletin boards are also made of aluminum, installation usually involves fixing the bulletin board to the side wall of the aluminum square tube with screws. On-site installation is relatively complex, time-consuming, and labor-intensive, and it is not convenient to quickly disassemble and reassemble the bulletin board from the aluminum square tube, thus requiring improvement. Utility Model Content

[0003] To facilitate quick assembly and disassembly of the bulletin board and aluminum square tubes and improve construction efficiency, this application provides a bulletin board structure that is easy to assemble and disassemble.

[0004] The bulletin board structure that is easy to assemble and disassemble provided in this application adopts the following technical solution:

[0005] An easy-to-assemble and disassemble bulletin board structure includes aluminum square tubes and a bulletin frame. A connecting block is provided on the back of the bulletin frame, and the connecting block can be inserted between the aluminum square tubes. A locking cavity is provided within the connecting block. A set of locking grooves are symmetrically formed on the inner sidewall of the locking cavity. A locking rod is slidably disposed within the locking groove. A guide block is fixedly disposed on the inner wall of the locking groove. A guide groove is formed on the outer wall of the locking rod, and the guide block is slidably disposed within the guide groove. A transmission bevel gear is sleeved on the outer wall of the locking rod. The transmission bevel gear is rotatably connected to the inner wall of the locking cavity, and the inner wall of the transmission bevel gear is threadedly connected to the outer wall of the locking rod. A rotating component is provided on the connecting block, which drives the two transmission bevel gears to rotate simultaneously. Locking holes are formed on the sidewall of the aluminum square tubes for inserting and abutting the locking rod.

[0006] By adopting the above technical solution, when installing the advertising frame and aluminum square tubes, the connecting block is inserted between the aluminum square tubes, and the locking groove and locking hole are aligned. The rotating component simultaneously drives two transmission bevel gears to rotate. When the transmission bevel gears rotate, the guide block abuts against the guide groove. The guide block and guide groove guide the locking rod, thereby driving the locking rod to slide away from the locking cavity in the locking groove. The locking rod is then inserted into the locking hole. By abutting against the inner wall of the locking hole, the connecting block can be fixed between the aluminum square tubes, thus quickly fixing the advertising frame to the side wall of the aluminum square tube. When the advertising frame needs to be disassembled, simply use the rotating component to drive the transmission bevel gears to reverse. The operation is convenient and quick, facilitating the rapid assembly and disassembly of the advertising frame and the aluminum square tube.

[0007] Preferably, the rotating component includes a rotating rod, a linkage bevel gear, and a handle. The rotating rod is rotatably mounted on the top of the connecting block. One end of the rotating rod located inside the drive cavity is connected to the linkage bevel gear, which meshes with two transmission bevel gears simultaneously. The other end of the rotating rod located outside the drive cavity is connected to the handle.

[0008] By adopting the above technical solution, when it is necessary to control the simultaneous rotation of the transmission bevel gears to drive the locking rod to slide, the rotating handle drives the rotating rod to rotate, and the rotating rod drives the linkage bevel gear to abut against the transmission bevel gear, thereby controlling the two transmission bevel gears to rotate simultaneously.

[0009] Preferably, the end of the locking rod away from the driving cavity is provided with a guide surface.

[0010] By adopting the above technical solution, when the locking rod is inserted into the locking hole, the guide surface can guide the locking rod, making it easier for the locking rod to be inserted into the locking hole.

[0011] Preferably, a plurality of locking holes are provided at equal intervals along the height direction of the aluminum square tube on the side wall.

[0012] By adopting the above technical solution and inserting the locking rod into different locking holes, the height of the advertising frame on the side wall of the aluminum square tube can be changed to adapt to different usage scenarios.

[0013] Preferably, the advertising frame and the connecting block are rotatably connected by a rotating shaft, and a damping plate is provided at the rotatable connection between the advertising frame and the connecting block.

[0014] By adopting the above technical solution, after the connecting block is fixed between the aluminum square tubes, the advertising frame and the connecting block can be driven to rotate. The damping plate increases the friction at the rotating connection, quickly fixing the angle of the advertising frame after rotation. The angle between the advertising frame and the connecting block can be changed according to the scene, making it easier to observe the advertising frame from different directions and further improving its applicability.

[0015] Preferably, the bottom of the advertising frame is provided with an installation groove for placing the advertising poster, the surface of the advertising frame is provided with an observation port that communicates with the installation groove, a transparent plate is provided in the observation port, a sealing plate is rotatably provided at the bottom of the advertising frame, the sealing plate is used to seal the installation groove, and a connecting piece is provided between the sealing plate and the advertising frame for connection and fixation.

[0016] Preferably, the connector includes a magnetic component and an adsorption component. The magnetic component is fixedly mounted on the outer wall of the advertising frame, and the adsorption component is mounted on the end wall of the sealing plate. The adsorption component and the magnetic component can be magnetically attracted to each other.

[0017] By adopting the above technical solution, the adsorption component and the magnetic component are separated from each other. After opening the sealing plate, the poster can be taken out of the installation slot. After replacing the poster, the sealing plate is rotated. The magnetic attraction between the adsorption component and the magnetic component fixes the sealing plate at the opening of the installation slot. The sealing plate can support the poster and seal the installation slot, effectively protecting the poster inside the installation slot.

[0018] Preferably, the end wall of the adsorption element is integrally provided with a protrusion.

[0019] By adopting the above technical solution, the protrusion can be moved to facilitate the separation of the adsorption component from the magnetic component.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By setting up a connecting block, locking cavity, locking groove, locking rod, guide block, guide groove, transmission bevel gear, locking hole, and rotating component, when installing the advertising frame and aluminum square tube, the connecting block is inserted between the aluminum square tubes. The rotating component simultaneously drives the two transmission bevel gears to rotate. When the transmission bevel gears rotate, the guide block and guide groove guide the locking rod, controlling the locking rod to be inserted into the locking hole. By using the locking rod to abut against the inner wall of the locking hole, the connecting block can be fixed between the aluminum square tubes, thereby quickly fixing the advertising frame to the side wall of the aluminum square tube. When it is necessary to disassemble the advertising frame, simply use the rotating component to drive the transmission bevel gear. The operation is convenient and quick, facilitating the rapid assembly and disassembly of the advertising frame and aluminum square tube.

[0022] 2. By setting up a rotating rod, a linkage bevel gear, and a handle, when it is necessary to control the simultaneous rotation of the transmission bevel gear to drive the locking rod to slide, rotating the handle drives the rotating rod to rotate, and the rotating rod drives the linkage bevel gear to abut against the transmission bevel gear, thereby controlling the two transmission bevel gears to rotate simultaneously. The operation is convenient and quick, and the cost is low.

[0023] 3. By setting up an installation slot, observation port, transparent plate, sealing plate, magnetic component, and adsorption component, the adsorption component and magnetic component are separated from each other. The sealing plate is opened, and the poster can be taken out of the installation slot. After replacing the poster, the sealing plate is rotated. The magnetic attraction between the adsorption component and the magnetic component fixes the sealing plate at the opening of the installation slot. The sealing plate can support the poster and seal the installation slot, effectively protecting the poster inside the installation slot. Attached Figure Description

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] This application discloses a display board structure that is easy to assemble and disassemble. (Refer to...) Figures 1 to 3 The device includes an aluminum square tube 1 and a display frame 11. A connecting block 2 is located on the back of the display frame 11, and the connecting block 2 can be inserted into the aluminum square tube 1. A locking cavity 21 is provided within the connecting block 2. A set of locking grooves 22 are symmetrically formed on the inner sidewall of the locking cavity 21. A locking rod 23 with a circular cross-section is slidably disposed within the locking grooves 22. A guide block 3 is fixedly disposed on the inner wall of the locking grooves 22, and the guide block 3 is integrally formed with the connecting block 2. A guide groove 31 is formed along the length of the outer wall of the locking rod 23, and the guide block 3 is slidably disposed within the guide groove 31. The guide block 3 and the guide groove 31 are mutually compatible. A locking hole 10 is provided on the sidewall of the aluminum square tube 1 for the locking rod 23 to be inserted and abut against it. A guide surface 5 is provided at the end of the locking rod 23 away from the driving cavity.

[0031] Reference Figure 2 and Figure 3A transmission bevel gear 24 is sleeved on the outer wall of the locking rod 23. The transmission bevel gear 24 is coaxially arranged with the locking rod 23 and is rotatably connected to the inner wall of the locking cavity 21. The inner wall of the transmission bevel gear 24 is threadedly connected to the outer wall of the locking rod 23. A rotating component 4 is provided on the connecting block 2. The rotating component 4 includes a rotating rod 41, a linkage bevel gear 42, and a handle 43. The rotating rod 41 is rotatably disposed at the top of the connecting block 2. One end of the rotating rod 41 located in the driving cavity is connected to the linkage bevel gear 42. The linkage bevel gear 42 simultaneously meshes with two transmission bevel gears 24. The other end of the rotating rod 41 located outside the driving cavity is connected to the handle 43. When installing the advertising frame 11 and the aluminum square tube 1, insert the connecting block 2 between the aluminum square tubes 1 and align the locking groove 22 with the locking hole 10. Then, turn the handle 43 to drive the rotating rod 41 to rotate. The rotating rod 41 drives the linkage bevel gear 42 to abut against the transmission bevel gear 24, thereby controlling the two transmission bevel gears 24 to rotate simultaneously. The guide block 3 abuts against the guide groove 31. The guide block 3 and the guide groove 31 guide the locking rod 23, thereby driving the locking rod 23 to slide away from the locking cavity 21 in the locking groove 22. Control the locking rod 23 to be inserted into the locking hole 10. By using the locking rod 23 to abut against the inner wall of the locking hole 10, the connecting block 2 can be fixed between the aluminum square tubes 1, and the advertising frame 11 can be fixed on the side wall of the aluminum square tube 1.

[0032] Reference Figure 2 The advertising frame 11 and the connecting block 2 are rotatably connected by a pivot. A damping plate is provided at the rotatable connection between the advertising frame 11 and the connecting block 2. After the connecting block 2 is fixed between the aluminum square tubes 1, the advertising frame 11 and the connecting block 2 can be driven to rotate. The damping plate increases the friction at the rotatable connection, so the angle of the advertising frame 11 after rotation can be quickly fixed. The angle between the advertising frame 11 and the connecting block 2 can be changed according to the scene, so that the advertising frame 11 can be easily observed from different directions, further improving its applicability.

[0033] Reference Figure 3 The locking holes 10 are arranged at equal intervals along the height direction of the aluminum square tube 1 on the side wall. By inserting the locking rod 23 into different locking holes 10, the height of the advertising frame 11 on the side wall of the aluminum square tube 1 can be changed to adapt to different usage scenarios.

[0034] Reference Figure 4The bottom of the advertising frame 11 has an installation groove 6 for placing the advertising poster. The surface of the advertising frame 11 has an observation opening 61 that communicates with the installation groove 6. A transparent plate 62, made of glass, is fixedly installed inside the observation opening 61. A sealing plate 63 is rotatably mounted at the bottom of the advertising frame 11 via a hinge. A connector 7 is provided between the sealing plate 63 and the advertising frame 11. The connector 7 includes a magnetic component 71 and an adsorption component 72. The magnetic component 71, which is a magnet, is fixedly mounted on the outer wall of the advertising frame 11. The adsorption component 72, which is an iron block, is fixedly mounted on the end wall of the sealing plate 63. A protrusion 8 is integrally provided on the end wall of the adsorption component 72. By moving the protrusion 8, the adsorption component 72 and the magnetic component 71 are separated, and the sealing plate 63 can be opened. The poster can be taken out from the mounting groove 6. After replacing the poster, rotate the sealing plate 63. The magnetic attraction between the adsorption component 72 and the magnetic component 71 will fix the sealing plate 63 at the opening of the mounting groove 6. The sealing plate 63 can support the poster and seal the mounting groove 6, effectively protecting the poster in the mounting groove 6.

[0035] The implementation principle of the easy-to-assemble and disassemble bulletin board structure in this application embodiment is as follows: When installing between the bulletin board frame 11 and the aluminum square tube 1, the connecting block 2 is inserted between the aluminum square tubes 1, and the locking groove 22 is aligned with the locking hole 10. Then, the handle 43 is rotated to drive the linkage bevel gear 42 to abut against the transmission bevel gear 24, driving the transmission bevel gear 24 to rotate. At this time, the guide block 3 guides the locking rod 23, thereby driving the locking rod 23 in the transmission bevel gear 24 to slide away from the locking cavity 21 in the locking groove 22, controlling the locking rod 23 to be inserted into the locking hole 10. By using the locking rod 23 to abut against the inner wall of the locking hole 10, the connecting block 2 can be fixed between the aluminum square tubes 1, thereby quickly fixing the bulletin board 11 to the side wall of the aluminum square tube 1. When it is necessary to disassemble the bulletin board 11, it is only necessary to use the rotating part 4 to drive the transmission bevel gear 24 to reverse. The operation is convenient and quick, facilitating the rapid assembly and disassembly of the bulletin board and the aluminum square tube 1.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
