Square utility blocks for use in outdoor building blocks

Abstract

The invention provides a square universal building block used in outdoor building blocks, which is composed of an upper cover and a lower cover. The upper cover and the lower cover have the same structure, and both include a cover plate, a side plate and a cylinder. The described The cover plate has a square structure, and the outer surface of the cover plate and side plates is provided with a non-slip coating. The anti-slip coating is provided with a texture to prevent the cover plate from being scratched. The diameter is the same as the diameter of the round hole, and one end of the cylinder is fixedly installed on the round hole; the side plate is perpendicular to the cover plate, and the side plate is distributed around the edge of the cover plate, and the side plate and the cover plate are fixedly connected Integral structure; each side of the side plate is provided with a rectangular slot that is sunken toward the direction of the cylinder, and the connection between the bottom surface and the side of the slot is provided with arc chamfers and slope transitions. The invention solves the disadvantages of the prior art. The building block has a simple and firm structure, and at the same time has a light weight and is not easily deformed.

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
