Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A spherical toy block, as shown in fig. 1-4, comprising an upper part 1 and a lower part 2, the upper part 1 and the lower part 2 combining to form a spherical structure; namely, the upper part 1 and the lower part 2 are of a hemispherical structure, and the interior is of a hollow structure. The plug 3 and the jack 4 are arranged at the joint of the upper part 1 and the lower part 2, the jack 4 is arranged at the top end of the upper part 1, and the plug 3 is arranged at the top end of the lower part. The upper part 1 and the lower part 2 are fixed by means of ultrasonic welding. During the use, insert plug 3 in the jack 4 of another spherical building blocks, realize the concatenation between the spherical building blocks. Of course, the connection method of the upper portion 1 and the lower portion 2 is not limited to the ultrasonic welding method, and preferably, the connection method may be fixed by screws. Specifically, jack 4 on the top of upper portion 1 extends to the centre of sphere and sets up head rod 7 to set up the fixed orifices that communicates with the jack on head rod 7, the plug 3 on the top of lower part 2 extends to the centre of sphere of spherical structure and sets up second connecting rod 8, and set up the screw on second connecting rod 8, the central line of fixed orifices and screw is on same straight line, and after upper portion 1 and lower part 2 make up, have the clearance between head rod 7 and the second connecting rod 8, fixed orifices and screw pass through the screw fixation.
