Description

Technical Field

[0001] This utility model relates to the field of teaching and conference presentation equipment, and in particular to a whiteboard. Background Technology

[0002] Currently available whiteboards are made of acrylic and have strong magnets at their four corners. These magnets allow the whiteboard to adhere to any iron furniture, and people often attach it to refrigerators for convenient use. However, acrylic whiteboards are prone to scratches and cracking over time; the strong magnets at the corners cannot be removed, and the other side is not usable for writing, meaning the whiteboard is not being used to its full potential.

[0003] While some solutions have been proposed to address the aforementioned issues, such as strengthening the whiteboard material or using special coatings to reduce scratches, these solutions often only solve part of the problem and may increase manufacturing costs or affect ease of use. Therefore, designing a whiteboard that is both durable and drop-resistant, and also features a detachable strong magnet, has become a pressing technical challenge. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] Example 1

[0031] A whiteboard, for reference Figures 1 to 4 The system includes a plate 1, which consists of a substrate and two panels. Each of the four sides of the plate 1 is equipped with protective components 2 for edge binding. These protective components 2 are made of aluminum alloy, which is both lightweight and strong. A groove 5 is machined on the side of the protective component 2 closest to the plate 1, and the side of the plate 1 fits snugly into the groove 5. To further enhance the stability of the connection, elongated protrusions 6 are provided on the inner wall of the groove 5. These protrusions 6 effectively increase the friction between the groove 5 and the side of the plate 1 when inserted. Furthermore, a cavity 7 is designed on the side of the protective component 2 away from the plate 1. This cavity 7 is used to mate with subsequent connecting components 3, thereby achieving a stable connection between multiple protective components 2.

[0032] The protective components 2 are interconnected via specific connectors 3. Magnetic components 4 are mounted on one side of each connector 3. The main function of the magnetic components 4 is to securely fix the entire whiteboard structure to a metal object such as a refrigerator door. To achieve this function, the connector 3 has a mounting part 31, through which the magnetic components 4 are securely mounted. The magnetic component 4 includes a strongly magnetic magnetic part 41, with a nut 8 fixed to the side of the magnetic part 41 near the mounting part 31. A connecting hole 9 is machined on the corresponding mounting part 31, and a bolt 10 passes through the connecting hole 9. During installation, the bolt 10 and the nut 8 are threaded together, thus tightly and securely fixing the magnetic component 4 to the connector 3. This connection method ensures both stability and ease of disassembly and replacement when needed. The connector 3 includes not only the mounting part 31 connected to the magnetic member 4, but also two plug-in parts 32. These two plug-in parts 32 are located at both ends of the mounting part 31 and have a π-shaped structure to adapt to the shape of the cavity 7 of the protective member 2 and achieve a tight plug-in fit. At the same time, the two plug-in parts 32 are provided with an included angle that matches the corner angle of the corresponding plate 1.

[0033] The mounting part 31 has a receiving groove 11 machined on it. This receiving groove 11 is used to place a specially designed stop 12. The main function of the stop 12 is to cover the bolt 10 and the connecting hole 9 after being embedded in the receiving groove 11, thereby achieving a stable connection while maintaining the neatness and aesthetics of the whiteboard. To further enhance the stability of the stop 12 and prevent it from accidentally falling off, the stop 12 is also machined with a post 13, and the corresponding mounting part 31 is provided with a plug hole 14. During installation, the post 13 is tightly inserted into the plug hole 14, thereby ensuring a stable connection between the stop 12 and the mounting part 31. In addition, a small slot 16 is machined at the corner of the receiving groove 11. Users can easily remove the stop 12 and the magnetic part 4 by inserting their fingernail or other small tools into the gap between the stop 12 and the receiving groove 11 for subsequent maintenance or replacement operations. Furthermore, the mounting section 31 is designed with a symmetrical structure on both sides, which means that when one side of the whiteboard becomes severely worn due to prolonged use, the user can remove the magnetic attachment 4, reverse its direction, and reinstall it on the mounting section 31. This design not only extends the lifespan of the whiteboard but also reduces the user's maintenance costs.

[0034] Working Principle: This invention relates to a whiteboard design that uses an aluminum alloy protective component 2 to cover and protect the edges and corners of the board body 1, preventing damage. Simultaneously, the mating structure of the groove 5 and the protrusion 6 increases friction, ensuring a stable connection between the protective component 2 and the board body 1. The cavity 7 design facilitates subsequent connection and splicing. Furthermore, the magnetic force of the magnetic component 4 secures the whiteboard to objects such as refrigerator doors, improving installation flexibility and convenience. The mating structure of the bolt 10 and nut 8 ensures a stable and reliable connection between the magnetic component 4 and the connecting component 3, while also facilitating user disassembly and maintenance.

[0035] Example 2

[0036] Reference Figure 1 The difference in this embodiment lies in the further improvement of the anti-slip design. Specifically, multiple anti-slip grooves 15 are machined on the surface of the protective component 2. These anti-slip grooves 15 are regularly or irregularly distributed, which can effectively increase the friction between the user's hand and the protective component 2, thereby preventing accidental slippage or loss of hand during use. At the same time, aligned anti-slip grooves 15 are also machined on the connector 3 at the corresponding insertion portions 32 at both ends of the protective component 2 to ensure good anti-slip effect during connection and disassembly.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
