Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a modular building unit. Background Art

[0002] Building block toys are very popular in the field of children's toys. By combining multiple modular units in different arrangements, they can create various styles and bionic models: animals, buildings, vehicles, etc., which can better train children's sense of spatial location and hands-on assembly skills, and improve children's imagination and creativity.

[0003] For some outdoor amusement equipment, modular splicing can also be used. Some are made of wood or metal. This type of equipment is bulky and inconvenient to carry. The splicing method is mostly plug-in, which makes the splicing method inflexible, the structure is unstable after splicing, and the shapes and styles that can be assembled are relatively limited; Others are made of foam materials. Although this type of equipment is relatively light, it is usually connected by adhesive or stacked. The overall structure is still unstable after construction, and the strength of the material is relatively fragile, which is not suitable for use in some scenes of outdoor amusement equipment;

[0004] For some toys with magnetic connections, such as magnetic pieces, although they are stable enough after magnetic connection, their size is relatively small, which is quite different from the actual size of bionic models: animals, buildings, vehicles, etc., and they are not realistic enough after assembly; and because of their small size, they can only be placed on the table for viewing after splicing, and cannot be used for outdoor expansion activities: children play on the assembled toys, or play in the interior space after construction. If the size is made the same as outdoor amusement equipment, the adsorption force is difficult to meet, and it is easy to be unstable. Utility Model Content

[0005] In order to solve the deficiencies in the prior art, a modular building unit is provided.

[0006] The utility model is implemented by the following technical solutions:

[0011] Furthermore, the adsorption portion includes a convex plate extending outward along the inner surface of the frame, the convex plate and the inner surface of the frame enclose an adsorption cavity with one end open, and the magnet is accommodated in the adsorption cavity.

[0012] Furthermore, the magnet is a radial magnet. When the magnet is placed in the adsorption chamber, there is a gap between both ends and the circumferential side of the magnet and the side wall of the adsorption chamber, and the gap range is: 5mm-30mm.

[0013] Furthermore, the mounting edge is provided with an annular limiting groove, and the frame is provided with an annular rib adapted to the annular limiting groove.

[0014] Furthermore, the main body is divided into a first area and a second area, the mounting edge is located in the first area, the mounting plate is located in the second area, the first area is wrapped by the frame, and the second area is not wrapped by the frame.

[0016] Furthermore, the mounting plate is provided with protrusions and / or mounting grooves.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Compared with the magnetic sheets and outdoor amusement equipment in the existing technology, the modular building unit combines the advantages of both: in terms of size, the size of the modular building unit is limited to an edge length of not less than 20cm, which is close to that of outdoor amusement equipment, making the constructed bionic model or structural model more realistic and can be taken outdoors for expansion activities, greatly enhancing its practicality; in terms of connection method, magnetic adsorption connection is adopted, and the magnetic strength is at least N30, which ensures the stability of the overall structure after splicing.
