Wooden magnetic building block with plastic shell and manufacturing method thereof

Abstract

The invention relates to the field of toys, in particular to a wooden magnetic building block with a plastic shell and a manufacturing method thereof. The outer surface of the building block comprisesat least one splicing surface for splicing with other building blocks; at least one groove is arranged on each splicing surface; the outer cover of the building block body is provided with a plasticshell; the plastic shell is used for closing the building block body in the inner part of the building block body, and a cavity is formed between each groove and the plastic shell; small magnets are arranged in each cavity. The magnetic force between the building block and the ground surface of the building block is strong, and mutual interference is not easy to occur among the small magnets inside the same building block.

Description

technical field [0001] The invention relates to the field of toys, in particular to a wooden magnetic building block with a plastic casing and a manufacturing method thereof. Background technique [0002] There are many types and varieties of toys. Building block toys, as an ancient toy, have been loved by people since ancient times, and they play an important role in the field of toys. [0003] Building block toys help to develop intelligence and train children's hand-eye coordination; the arrangement, joint, ring, symmetry, etc. in the building blocks are of great benefit to children's intellectual development. When building blocks, children must involve problems such as proportion and symmetry, which is conducive to the early development of mathematical concepts for children. Building blocks are also conducive to the development of children's imagination. Children need to use a variety of different types of building blocks to build the desired objects through their imag...

Problems solved by technology

[0007] First, because it is arranged inside, the distance between it and the building block outer surface will be relatively large, causing the magnetic flux to attenuate severely. In this way, the magnetic flux transmitted by the small magnet to the building block is insufficient, resulting in a decrease in the magnetic properties of the building blocks, which seriously Affect the playability of magnetic building blocks; the current solution is to use small magnets with high magnetic flux to improve the magnetic properties of building blocks, which not only greatly increases the production cost, but also brings the second problem below;

[0008] Second, after using small magnets with high magnetic flux, since they are all inside the building block, the distance between the small magnets inside the building block is much closer. The embarrassing scene where the magnetic attraction between them is smaller than the attraction between the small internal magnets, because the small internal magnets have been firmly attracted to each other, so they will not turn over in the cavity, so in the process of building It is impossible to achieve magnetic attraction between any two building surfaces, which also seriously affects the playability of wooden magnetic building blocks

[0009] 2. Since wood is a natural material, it is easy to mildew, and there are many small gaps on the surface that are easy to breed bacteria. The existing wooden building blocks are usually coated with varnish or colored paint on the surface of the building block for protection, but paint The protection time of the building blocks is short, and it is easy to fall off after a period of time, which affects the hygiene and safety of the building blocks, and children are prone to get sick after touching
