Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a column-hole building block structure and its toy. Background Technology

[0002] In building block toys, cylindrical building blocks often fit together with interlocking holes. During the injection molding process of cylindrical building blocks, misalignment can occur between the male and female molds when they separate. Taking a 5mm diameter cylindrical building block as an example, the mold can ensure that the misalignment on one side is within 0.03mm, and other angular dimensions are within 4.98–5.02mm. Figure 5 As shown, the parting surface area can only be controlled within 4.98 to 5.06 mm by the mold. However, when the parting surface size is 5.02 to 5.06 mm during assembly, it will result in a large insertion and extraction force, which will cause uneven insertion and extraction force in the 360° circumferential direction.

[0003] There are two existing methods to solve mold misalignment. One method is to use a travel position, but this will make the mold more complex. The other method is to cut a 0.03mm flat surface on one side of the block hole to offset the mold misalignment, but this will cause uneven stress. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a column hole building block structure and its toy.

[0005] According to the present invention, a column-hole block structure includes a block shaft and a block body;

[0006] The building block body has building block holes for splicing the building block shaft. The building block shaft is cylindrical. The parting surface areas on both sides of the injection-molded building block shaft are respectively flat, so that when the building block shaft is spliced ​​into the building block hole, the insertion and extraction force is kept in the range of 8 to 20 N.

[0007] Preferably, the offset of the parting surface region inward due to the level position is L, where L is 0.02 to 0.03 mm.

[0008] Preferably, the flat position is formed during injection molding of the building block shaft.

[0009] Preferably, the building block has a plurality of building block holes.

[0010] Preferably, the holes in the building blocks are blind holes or through holes.

[0011] Preferably, the outer surface of the flat surface is a plane or an arc surface.

[0012] Preferably, the building blocks are block-shaped or cylindrical.

[0013] Preferably, the two flat positions of the parting surface area on both sides of the block axis are arranged in a centrally symmetrical manner.

[0014] Preferably, the outer diameter of the building block shaft is 3 to 10 mm.

[0015] Preferably, the outer diameter of the building block shaft is 5 to 8 mm.

[0016] Preferably, the outer diameter of the building block shaft is 6 to 7 mm.

[0017] A toy according to this utility model includes the aforementioned column-hole building block structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention reduces interference between the block shaft and the block hole by setting a flat position on the parting surface area of ​​the block shaft, thus offsetting the external deformation caused by mold misalignment. When the block shaft is spliced ​​in the block hole, the insertion and extraction force is kept within the range of 8 to 20 N, ensuring uniform force during insertion and extraction. This insertion and extraction force allows users to easily complete the insertion and extraction operation. At the same time, it also prevents the assembled column hole block structure from naturally separating, improving the stability of the column hole block structure, enhancing the feel, and increasing the fun.

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] Example:

[0037] This utility model provides a column-hole building block structure, such as Figure 1 As shown, Figure 1 As shown, it includes a building block shaft 1 and a building block body 2. The building block body 2 has building block holes 21 for assembling the building block shaft 1. The building block shaft 1 is cylindrical. Due to misalignment during the parting of the male and female molds, the parting surface areas on both sides of the molded building block shaft 1 form protruding parts 12, such as... Figure 7 , Figure 8 As shown, the protruding part 12 protrudes by approximately 0.03 mm. The presence of the protruding part 12 can lead to excessive insertion and extraction force, affecting the user experience.

[0038] To address the issues of excessive insertion and extraction force and uneven circumferential insertion and extraction force, this invention creates flat surfaces 11 on both sides of the molding surface during the injection molding of the building block shaft 1. Figure 2 , Figure 3As shown, this design reduces the interference between the block shaft 1 and the block hole 21, ensuring that the insertion and extraction force remains within the range of 8–20 N when the block shaft 1 is inserted into the block hole 21. This force allows users to easily perform insertion and extraction operations, while also preventing the assembled block structure from naturally separating, thus maintaining relative stability, improving the feel, and enhancing the toy's fun factor.

[0039] Specifically, the outer side of the flat position 11 is a plane or an arc surface, preferably an arc surface. The distance between the outermost of the two flat positions 11 in the parting surface area on both sides of the building block shaft 1 is equal to the outer diameter of the building block shaft 1. Preferably, the two flat positions 11 in the parting surface area on both sides of the building block shaft 1 are arranged in a centrally symmetrical manner.

[0040] Specifically, the outer diameter of the building block shaft 1 can be 3-10 mm, preferably 5-8 mm, for example, 6 mm, 7 mm, etc. Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the outer diameter of the block shaft 1 is 5 mm, and the distance between the outermost two flat positions 11 of the parting surface area on both sides of the block shaft 1 is also 5 mm. Due to the flat position 11, the parting surface area is offset inward by a value of L, which is 0.02 to 0.03 mm.

[0041] In practical applications, the column-hole building block structure can be used in a variety of scenarios. For example, the building block 2 can be a block-shaped structure with multiple building block holes 21, which can be blind holes or through holes. Another example is that the building block 2 can be a cylindrical structure. In addition, the building block 2 can also be an irregularly shaped structure, such as a doll model or a part within a doll model. The column-hole building block structure has a very wide range of applications.

[0042] This utility model also provides a toy, including a column hole block structure. By setting the column hole block structure on the toy, the problems of excessive insertion and extraction force and uneven insertion and extraction force caused by shaft hole mating can be effectively solved. It is simple to operate and low in cost.

[0043] Comparative example:

[0044] like Figure 6 , Figure 7 , Figure 8 As shown, the outer diameter of the block shaft 1 is 5 mm. When the parting surface area on both sides of the block shaft 1 is not removed, the distance between the outermost two flat positions 11 is 5.06 mm. When the block shaft 1 is spliced ​​in the block hole 21, the insertion and extraction force is tested to be 60.7 N. The large insertion and extraction force greatly affects the player's feel and reduces the fun of the toy.
