Square all-purpose building block used for outdoor building block

Abstract

The present invention provides a square all-purpose building block used for an outdoor building block. The square all-purpose building block is composed of an upper cover and a lower cover, wherein structures of the upper cover and the lower cover are the same, either of the upper cover and the lower cover comprises a cover plate, a side plate and a round tube, the cover plate is of a square structure, outer surfaces of the cover plate and the side plate are provided with non-skidding coatings, the non-skidding coatings are provided with grains for preventing the cover plate from being scratched, a round hole is disposed in the center of the cover plate, the diameter of the round tube is the same as that of the round hole, one end of the round tube is fixedly installed on the round hole, the side plate and the cover plate are perpendicular, the side plate is arranged around the edge of the cover plate, the side plate and the cover plate are fixedly connected into an integral body, both sides of the side plate are provided with clamping rectangular slots sinking towards the round tube direction, and connection parts of the a bottom face and side faces of the clamping slots are provided with circular arc chamferings and slope transitions. Defects of the prior art are solved, and the building block is simple and secure in structure, light in weight and not easy to deform.

Description

technical field [0001] The invention provides a square universal building block, in particular a square universal building block with firm structure and light weight used in outdoor building blocks, which belongs to the technical field of building blocks. Background technique [0002] As a toy, building blocks have a long history. Building blocks are usually cubic wood or plastic solid toys. Generally, the surface of the building blocks is decorated with letters or pictures, allowing different arrangements or construction activities. The building blocks have various styles and can be assembled into houses, various animals, etc. Building blocks help develop intelligence, and the arrangement, joint, ring, symmetry, etc. in building blocks are all good for children's intelligence. When building blocks, children must be involved in issues such as proportion and symmetry, which is conducive to the early development of children's number concept. Building blocks are conducive to ...

AI Technical Summary

Problems solved by technology

Since the current building blocks are basically made of plastic, and the plastic is easy to expand and shrink in the outdoor environment, resulting in aging deformation

In addition, due to the large volume of outdoor building blocks, they must be made into hollow shapes. Otherwise, it will be difficult for children with heavy weight to use them. However, the firmness of their structures cannot be guaranteed after being made into hollow shapes. Deformation such as crushing and dislocation

In addition, there is a type of connecting piece in the building blocks, which is used to connect different building blocks, which is called "universal building blocks" in the industry. There are slots in the universal building blocks for installing connecting rods, so in the process of assembling Long-term plugging and unplugging of the connecting rods will cause wear of the slots and affect the firmness of the connection
