Description

Technical Field

[0001] The utility model relates to the field of building blocks, in particular to a magnetic square building block. Background Art

[0002] Magnetic building blocks have been gaining popularity in recent years as toys that combine both entertainment and education. These blocks, connected magnetically, can be easily assembled into various two- and three-dimensional structures, helping children develop spatial imagination, hands-on skills, and creativity. Consequently, magnetic building blocks are widely used in early childhood education and family entertainment.

[0003] The common magnetic block building block structure currently on the market mainly consists of two upper and lower cover plates and multiple side panels. Most existing magnetic block building block products adopt this design, in which the lower cover plate and side panels are usually not formed in one piece, but are fixed using ultrasonic welding technology. Although the ultrasonic welding process can provide high structural stability, it also exposes many problems in actual application. For example, the ultrasonic welding process produces severe noise and harmful gases to the human body, which not only affects the health of operators but also has a negative impact on the environment. In addition, the welding process requires a high level of positioning accuracy. The upper and lower cover plates need to be precisely matched and positioned with the side panels one by one, resulting in a cumbersome assembly process and low production efficiency.

[0004] The existing ultrasonic welding process requires the upper and lower covers to be individually aligned with the side panels, a cumbersome process that increases production costs and complexity. In particular, when the upper and lower columns need to align with the holes, deviations can occur during the welding process, impacting product quality and stability. Utility Model Content

[0005] To overcome the problems associated with ultrasonic welding processes used in existing magnetic cube building blocks, such as noise, smoke, and cumbersome operation, the present invention proposes an improved magnetic cube building block. By integrally forming the lower cover plate with the four side panels, the assembly process is simplified, additional mechanical assembly steps are avoided, and production efficiency is improved. Preferably, a riveted connection between the pins and the sockets is used, replacing the traditional ultrasonic welding process. This avoids the harmful release of gases caused by the activation of plastic molecules during ultrasonic welding, as well as the severe noise pollution caused by low-frequency or high-power ultrasound waves, which can cause discomfort. This ensures the robustness and durability of the building block structure. To further enhance the functionality and structural stability of the building block, a divider is located within the placement chamber, which can stably separate and position the magnetic blocks, preventing them from sliding or falling off during use. Through the rational design of the divider, the adsorption force of the building block can be effectively enhanced, ensuring that multiple building blocks can be tightly connected when spliced, thereby improving the stability of the building block structure. Furthermore, the divider design allows for more rational utilization of internal space, reduces material waste, and further improves the economic and environmental performance of the product.

[0025] Reference Figures 1 to 5 , a magnetic block building block, comprising: four side panels 2, an upper cover plate 3 and a lower cover plate 4; the four side panels 2 are connected in a ring shape at both ends to form a plurality of corners 5, and baffles 6 are provided on both sides of the plurality of corners 5, and the baffles 6 on both sides of the corners 5 form a placement chamber 7 with the four side panels 2, and the plurality of baffles 6 are provided with insertion holes 64; a magnetic block 8, which is used to be placed in the placement chamber 7; a separator 9, which is used to separate the magnetic blocks 8 placed in the same placement chamber 7; the lower cover plate 4 covers the lower opening of the four side panels 2 connected in a ring shape and is formed integrally with the side panels 2, and the upper cover plate 3 is provided with a plug post 31 adapted to the plug hole 64. When the magnetic block 8 and the separator 9 are both installed in the placement chamber 7, the plug post 31 is riveted into the plug hole 64 to make the four side panels 2, the upper cover plate 3 and the lower cover plate 4 form a whole.

[0026] Through the arrangement of the above-mentioned structure, the placement chamber 7 can stably accommodate the magnetic block 8 and the separator 9, and ensure that the magnetic block 8 will not slide or fall off during use. The arrangement of the separator 9 effectively prevents the displacement or mutual collision of multiple magnetic blocks 8 in the placement chamber 7, thereby ensuring the stability of the magnetic force and the adsorption effect. In addition, the reasonable arrangement of the separator 9 also improves the durability and stability of the overall structure. By integrally forming the lower cover plate 4 with the four side panels 2, the assembly process is simplified, additional mechanical assembly steps are avoided, and production efficiency is improved. Preferably, a riveted connection between the plug 31 and the socket 64 is adopted to replace the traditional ultrasonic welding process, thereby avoiding the noise and pollution that may be generated during the production process, and ensuring the firmness and durability of the magnetic block structure. In addition, the riveted connection also improves the accuracy of the assembly, making the magnetic block more environmentally friendly and efficient during the production process. The outer dimensions of the magnetic building blocks can vary according to different needs. The preferred dimensions are 25mm x 25mm x 25mm or 30mm x 30mm x 30mm, ensuring that the building blocks are suitable for children to hold and operate, and have sufficient strength and durability.

[0027] In this embodiment, the upper cover plate 3 covers the upper opening of the four side panels 2 connected in a ring shape, and the lower cover plate 4 covers the lower opening of the four side panels 2 connected in a ring shape and forms a cross angle 10 with the connection with the corner 5. The magnetic block 8 is arranged in the placement chamber 7 and is located at the cross angle 10. Through the setting of the above structure, the design of the cross angle 10 can concentrate the adsorption force of the magnetic block 8 on the edge area of ​​the magnetic block building block, so that multiple magnetic block building blocks can be tightly adsorbed when connected, thereby improving the overall adsorption effect and stability. Preferably, the cross angle 10 is set at the connection between the upper edge of the upper cover plate 3 and the four side panels 2, and the connection between the lower edge of the lower cover plate 4 and the four side panels 2. The magnetic block 8 is close to the cross angle 10, so that the magnetic force is more concentrated, thereby improving the overall adsorption effect.

[0028] In this embodiment, the placement chamber 7 includes a first placement chamber 71 and a second placement chamber 72, and the plurality of corners 5 include a first corner 51 and a second corner 52. The first corner 51 and the second corner 52 are arranged diagonally. The baffles 6 are provided on both sides of the first corner 51 and the second corner 52. The baffles 6 and the side panels 2 on both sides of the first corner 51 enclose the first placement chamber 71, and the side panels 2 on both sides of the second corner 52 enclose the second placement chamber 72. The first placement chamber 71 and the second placement chamber 72 are both provided with magnetic blocks 8 and the separators 9. Through the above-mentioned structural arrangement, the magnetic blocks 8 are respectively arranged in the first placement chamber 71 and the second placement chamber 72, ensuring the adsorption stability of the magnetic block structure at different angles, and further optimizing the distribution between the magnetic blocks 8, making the magnetic force more uniform and avoiding the situation where the adsorption force in a single direction is insufficient.

[0029] In this embodiment, the placement chamber 7 includes a third placement chamber 73 and a fourth placement chamber 74, and the multiple corners 5 also include a third corner 53 and a fourth corner 54. The third corner 53 is diagonally arranged with the fourth corner 54 and is adjacent to the first corner 51 and the second corner 52. The baffle 6 is provided on both sides of the third corner 53 and the fourth corner 54. The baffle 6 and the side panels 2 on both sides of the third corner 53 are enclosed to form the third placement chamber 73 and the side panels 2 on both sides of the fourth corner 54 are enclosed to form the fourth placement chamber 74. The third placement chamber 73 and the fourth placement chamber 74 are both provided with magnetic blocks 8 and the partition 9. Through the arrangement of the above structure, the magnetic blocks 8 are distributed in the first placement chamber 71, the second placement chamber 72, the third placement chamber 73 and the fourth placement chamber 74, forming multiple adsorption points, so that the adsorption effect of the magnetic block building blocks in different directions is more uniform. Compared with the structure in which the magnetic blocks 8 are distributed only through the first placement chamber 71 and the second placement chamber 72, this embodiment further improves the overall adsorption force by setting the third placement chamber 73 and the fourth placement chamber 74, and enhances the stability and durability of the building blocks during assembly and use.

[0030] In this embodiment, the separator 9 includes a first plate 91 and a second plate 92. The first plate 91 and the second plate 92 are arranged in a cross shape. An opening 11 is provided between the two baffles 6 of the first placement chamber 71, an opening 11 is provided between the two baffles 6 of the second placement chamber 72, an opening 11 is provided between the two baffles 6 of the third placement chamber 73, and an opening 11 is provided between the two baffles 6 of the fourth placement chamber 74. The baffles 6 are enclosed by the side panels 2. The two sides of the first plate 91 and the two sides of the second plate 92 can be respectively arranged in the first placement chamber 71, the second placement chamber 72, the third placement chamber 73, and the fourth placement chamber 74 through the openings 11. The magnetic block 8 is arranged at the upper and lower ends of the first plate 91 and the upper and lower ends of the second plate 92. Through the above-mentioned structural setting, the cross-shaped design of the separator 9 can effectively fix the magnetic block 8 in the placement chamber 7, preventing the magnetic block 8 from being displaced or colliding with each other during use. At the same time, the arrangement of the first placement chamber 71, the second placement chamber 72, the third placement chamber 73, and the fourth placement chamber 74 allows the magnetic blocks 8 to be rationally separated and fixed, improving the overall structural strength and adsorption effect. The design of the separator 9 also simplifies the assembly process of the magnetic blocks and improves production efficiency.

[0031] In this embodiment, notches 93 for installing the magnetic block 8 are provided at both ends of the side of the first plate 91 and the second plate 92 close to the upper cover plate 3. The notch 93 is L-shaped, and a placement groove 931 is formed between the side wall of the notch 93 and the side plate 2, and the magnetic block 8 is arranged in the placement groove 931. Through the setting of the above structure, the notch 93 can provide a stable installation space for the magnetic block 8, ensuring the fixation of the magnetic block in the placement room. The notch 93 can be L-shaped or U-shaped. Preferably, the L-shaped notch 93 can not only better fix the magnetic block 8, but also simplify the processing and installation process. Compared with the U-shaped notch, the design of the L-shaped notch is more convenient for production, and can reduce the use of materials without sacrificing stability, further improving the economy of the product.

[0032] In this embodiment, grooves 94 are further provided at the upper ends and lower ends where the first plate 91 and the second plate 92 intersect. By setting the above-mentioned structure, by setting the groove 94 in the intersection area of ​​the first plate 91 and the second plate 92, the groove 94 can be U-shaped or V-shaped. Preferably, the groove 94 is designed to be U-shaped. This U-shaped design has the significant advantages of effectively reducing material usage and reducing production costs. The U-shaped groove 94 can reduce the amount of material required for the plate while maintaining structural strength. Compared with other shapes, the design of the U-shaped groove 94 has a larger internal space, which can reduce the amount of material used by optimizing the internal structure without affecting the overall carrying capacity and stability of the magnetic block building blocks.

[0033] In this embodiment, a plurality of the baffles 6 are provided with a rivet post 63 on one side away from the side panel 2. The insertion hole 64 is provided at the top of the rivet post 63, and the insertion post 31 is riveted onto the rivet post 63 through the insertion hole 64. Through the above-mentioned structural arrangement, the design of the rivet post 63 and the insertion hole 64 can effectively replace the traditional welding process, avoiding the noise and smoke pollution generated during the welding process, while ensuring the stability of the overall structure of the building block. Preferably, two rivet posts 63 are provided at each corner. The double rivet design greatly improves the compressive resistance and firmness of the building block structure, ensuring the long-term durability of the magnetic block during use.

[0034] In this embodiment, a guide plate 32 is also provided on the upper cover plate 3, and the baffle 6 includes a first baffle 61 and a second baffle 62, and the first baffle 61 and the second baffle 62 are arranged on the same side plate 2, and the rivet pressing column 63 includes a first rivet pressing column 631 and a second rivet pressing column 632, the first rivet pressing column 631 is fixedly arranged on the first baffle 61, and the second rivet pressing column 632 is fixedly arranged on the second baffle 62, and the first rivet pressing column 631 and the second rivet pressing column 632 are close to each other so that a first slide groove 65 is formed between the first rivet pressing column 631, the first baffle 61 and the side plate 2, and a second slide groove 66 is formed between the second rivet pressing column 632, the second baffle 62 and the side plate 2, the openings of the first slide groove 65 and the second slide groove 66 are arranged opposite to each other, and the two side edges of the guide plate 32 can be slidably inserted into the first slide groove 65 and the second slide groove 66. With the above-described configuration, the guide plate 32 can slide smoothly within the first and second chutes 65, 66, ensuring precision and stability during connection and use. The guide plate 32 can be made of a wear-resistant plastic material such as polypropylene (PP), ABS plastic, or polycarbonate (PC). Preferably, the guide plate 32 is made of ABS plastic to ensure sufficient strength and good wear resistance for long-term use.

[0035] In this embodiment, the plug 31 is a cylinder 311, and a protrusion 312 is provided on the outer side surface of the cylinder 311. The protrusion 312 is arranged along the extension direction of the cylinder 311, and a cut surface 313 is provided on the end of the protrusion 312 close to the top of the cylinder 311. The top of the cylinder 311 is arranged in a hemispherical surface. Through the arrangement of the above structure, by providing the protrusion 312 on the outer side surface of the cylinder 311, the friction between the plug 31 and the socket 64 can be increased, making it more secure after assembly. Preferably, the cut surface 313 is a bevel design with an inclination angle ranging from 30° to 45°, which can effectively reduce the friction resistance generated by the plug 31 when it is inserted into the socket 64. The hemispherical design enables the plug 31 to quickly and easily enter the socket 64, avoiding the jamming problem that may be caused by the traditional flat-top design.

[0036] In this embodiment, the four side panels 2, the upper cover 3, and the lower cover 4 are made of ABS plastic. This configuration significantly improves the durability and impact resistance of the magnetic building blocks. ABS plastic has excellent mechanical strength and wear resistance, and can withstand long-term use without deformation or breakage.
