Description

Technical Field

[0001] This utility model belongs to the field of teaching aids technology, specifically relating to a magnetic accessory for teaching aids. Background Technology

[0002] With the continuous development of modern teaching methods, the types and functions of teaching aids are also constantly being enriched. Magnetic accessories, as a common teaching aid, are widely used on teaching equipment such as blackboards and whiteboards to fix and display teaching aids such as levers, pulleys, and models. However, existing magnetic accessories have the following main drawbacks in practical use:

[0003] 1. The high hardness of the magnets makes them easy to scratch the blackboard surface.

[0004] Traditional magnetic accessories typically use round, strong magnetic blocks, which are quite hard and have low friction with the blackboard. When in direct contact with the blackboard surface, they are prone to slipping, scratching the blackboard, and affecting the blackboard's lifespan and appearance.

[0005] 2. Adhesive bonding methods are prone to loosening:

[0006] Traditional magnetic accessories typically use glue to fix the magnet to the base, but glue bonding has poor stability and is prone to loosening after long-term use, which may even cause the magnet to fall off, posing a safety hazard. Utility Model Content

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0008] A magnetic accessory for teaching aids includes a base, a magnetic block mounted on the bottom of the base, the magnetic block and the base being connected by several fasteners, and a soft rubber coating layer on the outside of the magnetic block.

[0009] As a preferred technical solution for magnetic accessories used in teaching aids, the magnetic block has a cuboid structure and the sides of the magnetic block are rounded.

[0010] As a preferred technical solution for magnetic accessories used in teaching aids, the overlay layer is made of TPE rubber.

[0011] As a preferred technical solution for magnetic accessories used in teaching aids, the base is provided with a fastening groove, the bottom of the fastening groove is provided with a through positioning groove, the magnetic block is provided with a positioning protrusion that assembles with the positioning groove, the positioning protrusion is provided with an assembly hole, and the fastener is placed in the fastening groove and connected to the magnetic block through the assembly hole.

[0012] As a preferred technical solution for magnetic accessories used in teaching aids, the top of the fastener is not higher than the upper surface of the base.

[0013] As a preferred technical solution for magnetic accessories used in teaching aids, the base is provided with mounting holes for mounting teaching aids, the mounting holes being divided into lateral mounting holes located on both sides of the base and a central mounting hole located in the center of the base.

[0014] Compared with the prior art, this application has the following beneficial technical effects:

[0015] 1. The design of using a rubber coating to cover the magnetic blocks can effectively prevent the magnetic blocks from scratching the blackboard surface and increase the coefficient of friction with the blackboard surface. Under the same magnetic force, the friction is greater, the base is less likely to slip, and the stability is stronger.

[0016] 2. The base and magnet are connected by fasteners, which are less prone to loosening and more stable than traditional glue bonding. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] refer to Figure 1 A magnetic accessory for teaching aids includes a base 10, with a magnetic block 20 mounted on the bottom of the base 10. The magnetic block 20 and the base 10 are connected by several fasteners 30. The magnetic block 20 is covered with a soft, rubber-coated layer to effectively prevent direct contact between the magnetic block 20 and the blackboard, thus preventing scratches on the blackboard surface and extending the blackboard's lifespan. Furthermore, the rubber-coated layer increases the coefficient of friction with the blackboard surface, resulting in greater friction under the same magnetic force, making the base 10 less prone to slipping and providing greater stability.

[0027] Specifically, the magnetic block 20 has a cuboid structure. This cuboid structure reduces empty space, making the product design more compact and smaller in size. The sides of the magnetic block 20 are rounded to prevent the edges from breaking through the rubber coating. The rubber coating is made of TPE rubber. TPE rubber has a high coefficient of friction, further increasing the friction between the base 10 and the blackboard, ensuring that the components do not easily slip during use. Furthermore, TPE rubber has a certain degree of elasticity, which can cushion the vibration of the teaching aids, reducing the risk of components loosening or slipping due to vibration.

[0028] To ensure the assembly stability of the magnet 20 and the base 10, the base 10 is provided with a fastening groove 11, and the bottom of the fastening groove 11 is provided with a through positioning groove 12. The magnet 20 is provided with a positioning protrusion 21 that assembles with the positioning groove 12, and the positioning protrusion 21 is provided with an assembly hole 22. The fastener 30 is placed in the fastening groove 11 and connected to the magnet 20 through the assembly hole 22. The design of the positioning groove 12 and the positioning protrusion 21 ensures the precise alignment of the magnet 20 and the base 10. The fastener 30 is connected through the assembly hole 22, providing stronger fixing force and preventing the magnet 20 from loosening. The top of the fastener 30 is not higher than the upper surface of the base 10, ensuring that the overall installation platform is level, without protrusions, and will not interfere with the installation or movement of the teaching aids, improving the flexibility and compatibility of use.

[0029] This application also designs the assembly layout of the base 10. Specifically, the base 10 is provided with mounting holes for mounting teaching aids. These mounting holes are divided into lateral mounting holes 13 located on both sides of the base 10 and a central mounting hole 14 located at the center of the base 10. This layout design ensures that the upper surface of the base 10 completely conforms to the teaching aids, improving assembly stability. (Reference) Figure 2 and Figure 3 Considering the general specifications of teaching aids, the mounting holes adopt a seven-hole layout, and the number of magnetic blocks 20 is arranged in a double magnetic block 20 or four magnetic block 20 layout depending on the size of the teaching aids.

[0030] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
