Spherical building block

Abstract

A spherical building block is disclosed which comprises an upper part and a lower part, wherein the upper part and the lower part are connected to form a spherical structure, a plug and a jack are arranged at the joint of the upper part and the lower part, the jack is arranged at the top end of the upper part, and the plug is arranged at the top end of the lower part. The building blocks are arranged to be spherical, with the interiors being hollow, after connecting pieces are fixed when the building blocks leave a factory, the plugs are in interference fit with the jacks, the jacks are formedin arc-shaped faces, when the plugs are inserted, the inner edges of the jacks deform towards the centers of spheres, meanwhile, restoring force can be generated to act on the plugs, and the plugs can be firmly inserted into the jacks. Besides, the joints are arranged on the jacks to guide the deformation of the jacks, so that the hand feeling of a user is better, and due to inevitable errors inproduction, it can be ensured that the plugs can be firmly fixed in each jack through the structure; even after long-term use and abrasion, normal use of the jacks can be ensured; the tightness of screws does not need to be frequently adjusted.

Description

technical field [0001] The invention relates to a spherical building block. Background technique [0002] The most common building blocks are square, but rarely have a spherical structure. The spherical structure is very difficult to produce. The existing spherical building blocks are usually connected by splicing, that is, producing solid balls and independent connecting rods, and then processing on the surface of the solid balls. Sockets or screw holes are connected to solid balls through connecting rods; the production process of the above-mentioned spherical building blocks is complicated and the production cost is high; especially due to the unavoidable existence of certain errors during production, the sockets and connecting rods are not well matched. , Some sockets are too tightly fitted, and some sockets are gapped; in addition, after long-term use, the socket and the connecting rod are worn, and the connection will be loose, and it is easy to separate and fall off. ...
