[0008] A plurality of cardboard building block units can be combined with each other through a plurality of cardboard building block connectors to achieve a variety of combinations with different shapes.

[0009] The combined panel is divided into an integrated six-sided cardboard and a separated six-sided cardboard. The integrated six-sided cardboard is formed as a whole, and adjacent board surfaces are plugged and snapped together to form a rectangular building block unit; the separated six-sided cardboard is two pieces of combined cardboard, and the two pieces of cardboard are plugged and snapped together to form a rectangular building block unit.

[0010] The advantages of the present invention over existing technologies are: due to the above structure, the building blocks are cleverly locked together, and the multiple cardboard building block connectors can be combined to create a variety of different shapes. The present invention has an ingenious and reasonable structural design and can be applied to toys, teaching aids, large-scale development, and other fields.

[0018] In order to further explain the technical solution of this aspect, the present invention is described in detail below through specific embodiments.

[0019] Figure 1 The cardboard building block module shown is made of multiple layers of corrugated paper through a special cardboard processing technology.

[0020] Figure 4 The building block unit made of cardboard shown can be folded and assembled into a complete building block unit after processing.

[0021] Figure 1-7 A universal combination building block made of cardboard includes a building block unit made of cardboard and a building block connector made of cardboard. The building block unit includes an integrated modular panel, and the joint surfaces of the modular panel are connected to form a rectangular box; one joint surface end of the modular panel is provided with a first connector and a second strip groove, and the adjacent joint surface ends are provided with a first strip groove and a second connector. When the modular panels are spliced, the first connector is installed and inserted into the first strip groove, and the second connector is inserted into the second strip groove. The adjacent joint surfaces are plugged in to stabilize the building block unit structure; each end surface of the building block unit is provided with four third strip grooves, and the four third strip grooves form a rectangle coaxial with the end surface, and the four third strip grooves are not aligned. The clamping piece can be inserted into the third strip groove of the building block unit, and the clamping piece includes a connecting plate and an insertion plate symmetrically arranged at both ends of the connecting plate, and the free end of the insertion plate is crescent-shaped; when the two symmetrical insertion plates are folded into a vertical state, the crescent-shaped tip of the insertion plate is close to the end face of the connecting plate, and the clamping piece can be locked; the clamping piece is inserted into the third strip groove of two adjacent building block units and pushed forward, and the crescent-shaped tip of the insertion plate and the end face of the connecting plate tightly clamp the end face of the building block unit, so that the two building block units are closely connected, and the firmness is higher than that of ordinary paper boxes; multiple building block units made of cardboard can be combined with each other through multiple building block clamping pieces made of cardboard to achieve a variety of combinations with different shapes.

[0022] In this embodiment, the modular panel is divided into two types: an integrated six-sided cardboard and a separable six-sided cardboard. The integrated six-sided cardboard is integrally formed, and adjacent board surfaces are plugged and snapped together to form a rectangular building block. The integrated structure is convenient for placement and transportation; the separable six-sided cardboard is composed of two pieces of modular cardboard, which are plugged and snapped together to form a rectangular building block. The modular structure is convenient for plugging and snapping, and is more convenient to disassemble.

[0023] In this embodiment, the cardboard building block units and the cardboard building block connectors are both made of corrugated cardboard and are made of multiple layers of corrugated cardboard.

[0024] In this embodiment, the overall shape of the building block unit made of cardboard is a cube. The building block unit made of cardboard is made of multiple layers of corrugated cardboard, which are formed in one step through a cardboard processing process and three-dimensionally spliced ​​together.
