Building block lap joint structure

Abstract

The invention relates to a building block lap joint structure. The problem is solved that the design in the prior art is not reasonable. The building block lap joint structure comprises a connecting column arranged on an adapting connection block, wherein the connecting column penetrates into an inner cavity, at least one end of the connecting column extends to the outer side of the adapting connection block, a building block is arranged on at least one side of the adapting connection block and is provided with a connecting hole, an inner thread is arranged in the connecting hole, an outer thread meshed with the inner thread is arranged at the end, extending to the outer side of the adapting connection block, of the connecting column, a first magnetic body is arranged at one end of the connecting column, a control seat is arranged at the upper end or the lower end of the adapting connection block, a rotary rod is arranged on the control seat, one end of the rotary rod is located in thecavity, a second magnetic body is arranged at the end of the rotary rod, the other end of the rotary rod extends to the outer side of the control seat and is connected with a rotary driving mechanism. The building block lap joint structure has the advantages that bolt rotation is controlled by utilizing the principle that same charges of the magnetic bodies repulse each other and opposite chargesof the magnetic bodies attract each other, two or three building blocks are connected in a threaded mode through magnetic control, the connecting firmness is strong, and the playability is high.

Description

technical field [0001] The invention belongs to the technical field of toys, and in particular relates to a building block overlapping structure. Background technique [0002] Building blocks are usually cubic wooden or plastic solid toys, usually decorated with letters or pictures on each surface, allowing different arrangements or construction activities. Building blocks have various styles, which can develop children's intelligence and can be assembled into houses and various animals. Wait. There are two main types of traditional building block toys, the first is wooden building blocks, the building blocks can be placed in different shapes, and there are no connecting parts between the building blocks; the second is plug-in building blocks; these two kinds of building blocks exist The big problem is that the first type of building blocks tends to collapse during placement; the second type of building blocks is prone to difficulty in plugging in and out or jamming. This ...

AI Technical Summary

Problems solved by technology

[0004] The above solution solves the problem that the existing building blocks are easy to collapse to a certain extent, and improves the stability of the building blocks through the mutual attraction of the magnets, but the solution still exists: the playability is poor, and the connection is not strong enough when placed The problem
