Description

A granular building block toy conversion plug and its manufacturing method technical field

The present invention and the technical field of R&D and manufacturing of "granular building block toys" splicing granules, especially relate to a granular building block toy conversion plug and a manufacturing method.

The conversion plug of a granular building block toy in the present invention refers to a plug that can directly splice the "small particles" splicing particles with pin holes in the "6mm particle" building block toy with the splicing particles with pin holes in the building block toy .

Background technique

As shown in Fig. 1a, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, they are structural schematic diagrams of several typical latches commonly used in "granule" building block toys.

The structure of the various plugs includes three basic parts: A, B, and C: for the convenience of annotation, this application defines the structure of the plugs as follows: the various plugs include the first insertion end A, the limit Platform B, the second plug-in terminal C three parts.

Taking the "small particle" building block toy as an example, make a brief note on the size and structure of the various pins. The "small particle" building block toys refer to building block toys such as "Lego classic particles".

In the "small particle" building block toy, the dimensions of the first plug-in end A, the limiting platform B, and the second plug-in end C of the various bolts are all related to the basic size of 8 mm: the first plug The diameters of the connecting end A and the second plug-in end C are both 0.6 times of 8 mm, that is, 4.8 mm, and the axial lengths of both are "n times of 8 mm—0.2 mm" (n is a natural number). The axial length of the second insertion end C of the type pin is "0.5 times of 8 mm - 0.2 mm", that is, 3.8 mm; the diameter of the limiter B is 0.7 times of 8 mm, that is, 5.6 mm, and the axial length is 0.1 times or 0.2 times of 8 mm, that is, 0.8 mm or 1.6 mm.

The main dimensions of other splicing particles in the "small particle" building block toy are also designed based on the basic size of 8 mm: the height of the "board" is 0.4 times that of 8 mm, that is, 3.2 mm, and the height of the "brick" is 1.2 times of 8 millimeters, that is, 9.6 millimeters, the side lengths of "board" and "brick" are "n times of 8 millimeters—0.2 millimeters" (n is a natural number).

According to the size specifications and structural characteristics of the splicing particles of "small particle" building block toys, the research and development personnel have developed a particle-type building block toy with "6 mm" as the basic size parameter. For the convenience of annotation, this application uses "6 mm" "Particulate building block toys" as the basic size parameter are defined as "6mm granular" building block toys.

As shown in Figure 10, the "6mm particle" building block toys and the "small particle" building block toys basically include three types of splicing particles: I, II, and III: type I and type II are strip-shaped splicing particles, and the difference is that The arrangement of the pin holes on the bar-shaped mosaic particles is different; the type III mosaic particles are box-shaped, and the arrangement of the pin holes on the frame is the same as that of the type I mosaic particles or the type II mosaic particles. The number of pin holes on the shaped splicing particle frame is usually odd, that is, 3 holes, 5 holes, 7 holes, 9 holes, 11 holes, 13 holes, 15 holes, and also 2 holes, 4 holes, and 6 holes.

Compared with "small particle" building block toys, the scenery modeled by "6mm particle" building block toys is more exquisite, delicate and lifelike, and the texture of the scene shape is stronger.

If the "6mm particle building block toy" and the "small particle" building block toy are combined for the mosaic design of the scene shape, the respective advantages of the "6mm particle" building block toy and the "small particle" building block toy can be fully utilized to splice out More pleasing scenery modeling.

From the relationship between the main size of the "small particle" building block toy splicing particles and 8mm, it can be deduced that the size and structure of the pins used in the "6mm particle" building block toy are similar to the "small particle" building block toy, except that The size is a little smaller. In the "6 mm particle" building block toy, the dimensions of the first plug-in end A, the limiting platform B, and the second plug-in end C of the various pins are all related to the basic size of 6 mm: the first The diameters of the plug-in end A and the second plug-in end C are both 0.6 times 6 mm, that is, 3.6 mm, and the axial lengths of both are "n times 6 mm-0.2 mm" (n is a natural number), only The axial length of the second insertion end C of the Type III pin is "0.5 times 6 mm - 0.2 mm", that is, 2.8 mm; the diameter of the limiter B is 0.6 times 6 mm, that is, 4.8 mm, the axial length It is 0.25 times 6 mm, or 1.5 mm.

Therefore, if a plug that can directly splice the splicing particles of the "small particle" building block toy and the splicing particle of the "6 mm particle" building block toy is designed, it can easily solve the problem of combining the "6 mm particle" building block toy with the "6 mm particle" building block toy.
