A building block that can be connected

technical field

The invention relates to the technical field of building block toys, in particular to a movably connected building block.

Background technique

Building block toys have a long history and have a special effect on exercising and improving children's hands-on ability, observation ability, and inspiring intelligence. Building block toys are assembled by building blocks of various shapes and specifications to form toys of different shapes. Building blocks have developed from simple geometric parts at the beginning to various forms such as figures, animals, plants, and various natural objects. Only with the development of modernization can we assemble more exquisite toys. This puts forward higher requirements for the connection structure between the building blocks themselves, in order to meet the needs of manufacturing and accurate expression effects. For example, the active connection structure adopted in the existing building block toys generally uses the ball at one end of the connecting rod to be inserted into the groove of a base for rotation. If it is necessary to rotate in multiple directions, the existing structure only It can be achieved by splicing two connecting structures, or setting two spherical grooves on the base, which will increase the volume of the base, and obviously cannot be applied to building block products with small volume and flexible rotation requirements.

The first rotating member 2 includes a first rod body 21 and a rotatable spherical cover 22 arranged in the cavity, one end of the first rod body 21 is connected with the spherical cover 22, and the other end of the first rod body 21 passes through the first The through hole 102 can swing in the first through hole. The second rotating member 3 includes a second rod body 31 and a rotatable spherical part 32 arranged in the inner cavity of the spherical cover 22. One end of the second rod body 31 is connected to the spherical part 32, and the other end of the second rod body 31 is passed through. pass through the second through hole 103 and can swing in the second through hole. When the second rod body 31 is moved, the spherical part 32 can rotate in the inner cavity of the spherical cover.

Specifically, the cavity may be a spherical cavity 101, the outer diameter of the spherical cover 22 is slightly smaller than the diameter of the spherical cavity 101, the inner cavity of the spherical cover 22 is a large hemispherical shape, and the outer diameter of the spherical part 32 is slightly smaller than The diameter of spherical cover 22 lumens. This design ensures overall stability during rotation and avoids shaking caused by excessive diameter differences.
