Problems solved by technology

The disadvantage of this patent is that the magnetic building blocks are rigid, the suction edge is strong, the user's adsorption point is selected and not controlled independently, and the patent uses permanent magnets as the magnetic source of adsorption, although it solves the problem of face-to-face repulsion , to achieve all-round adsorption, but relying on the selection of the north and south polarities, further fine operations such as rotation cannot be performed after adsorption, and the user experience and safety as a child are lacking

Embodiment 1

[0064] refer to Figure 1 to Figure 3 , a magnetic building block that can be folded and adsorbed arbitrarily according to the present invention, comprising no less than one unit member sheet forming the building block, characterized in that the unit member is provided with four creases 2 on the core layer 1 and closely connected with the The flexible amphoteric magnetic layer 3 outside the crease area on both sides of the outer side of the core layer, the thickness of the amphipathic magnetic layer is 0.7mm, the core layer 1 is an isosceles trapezoidal synthetic paper sheet with a thickness of 0.15mm, and the crease 2 2 parallel indentations are set on the edge, chamfers are set at both ends of the creases, the width of the creases is not less than 1.9mm, and the creases divide the core layer into 5 equilateral triangles that are closely arranged in staggered planes , the side length of the triangle is 48mm, and the area of ​​the core layer is the sum of the areas of 5 equila...

Embodiment 2

[0079] refer to Figure 5 with Image 6 , the present invention is a foldable magnetic building block that can be adsorbed arbitrarily. This embodiment is the same as embodiment 1 except that the fabrication of the bisexual magnetic layer is different from embodiment 1 as follows.

[0080] The making of described bisexual magnetic layer magnetic layer is as follows:

[0081] Ingredients: Refer to Table 1 below.

[0082] Internal mixing: mix the anisotropic ferrite powder and soft magnetic powder according to the proportions in Table 1, respectively, using an internal mixer to mix the rubber, and the clinker is discharged after the mixing temperature reaches 120~150°C.

[0083] Open refining: use the open mixer to mix the mixed materials separately.

[0084] Refining and crushing: Refining the refined film into small balls with an internal mixer and crushing with a crusher.

[0085] Calendering: The crushed pellets are directly calendered using a calender to process anisotr...

Abstract

The invention discloses a foldable magnetic building block capable of being randomly attracted and a preparation method. The building block comprises at least one unit component sheet forming the building block, and is characterized in that four impresses and a flexible double-polarity magnetic layer closely connected to the outer side of a core layer outside the impress area are arranged on the core layer of the unit component sheet. The building block is a non-rigid sandwich structure, double connecting modes that the complete edges and complete faces of the building block can be finely adjusted is achieved, according to the edge connecting mode, free selecting folding of an arbitrarily angle within 360 degrees can be carried out with an edge fold as the axis, no repellent face exists during face connection, attraction force is even, the building block can continue to move and rotate after two faces are attracted, and the building block is not limited by passive selection of the south and north polarity in the prior art; attraction is achieved at the highest position, attraction points cannot be independently selected, the building block is autonomously and creatively spliced bychildren, a swinging three-dimensional space structure is created from a planar structure, and the intelligence promoting and enlightening effect of the building block is outstanding.

Description

technical field [0001] The invention relates to the field of toys, in particular to a foldable and arbitrarily adsorbed magnetic building block and a preparation method thereof. Background technique [0002] Existing building block toys have a variety of connection methods, some are connected by embedding each other on the surface, and some are connected by inlaying or installing permanent magnets in the building block or on the edge of the building block to realize the adsorption connection: realize edge adsorption or edge line segment adsorption, realize Points on the surface snap to. The above connection methods have their own advantages and limitations, but the flexibility, educational enlightenment, diversity and safety of the connection used by building blocks are the unremitting pursuit of building block manufacturers. [0003] Most American Lego blocks are connected by convex-convex occlusal connections. The connection surface can only be set on the concave-convex s...
