Description

Technical Field

[0001] The invention relates to an assembling toy, in particular to a splicing building block assembly with adjustable combination strength and a splicing structure thereof. Background Art

[0002] In the prior art, there are various splicing type building block toys, such as Lego building blocks, etc., which are widely popular because they are conducive to the cultivation of children's hands-on ability and spatial imagination ability.

[0003] From the specification of Chinese invention CN206240077U, we know another scheme called "a spliced ​​building block component". This invention is a spliced ​​building block component, which is a square body as a whole. The spliced ​​building block component of this structure can realize various forms of bridging, has good combination performance, rich shapes, high degree of freedom of combination, and good shape effect. However, it has the following problems:

[0004] 1. The protrusions of the spliced ​​building block components of this structure are thin-walled hollow structures. The ribs in the grooves squeeze the protrusions to achieve an adaptation effect. The protrusions are easy to deform and the combination strength is unstable.

[0005] 2. When the spliced ​​building block components of this structure are combined, the combination strength cannot be changed, and the combination strength cannot be increased or decreased according to the combination requirements.

[0006] 3. The closed loop combination effect of the spliced ​​building block components of this structure is as follows Figure 1 As shown, when the spliced ​​building block components of this structure are combined into several closed ring structures, only one closed ring can be structurally connected from head to tail, and one end of the remaining closed rings cannot be structurally connected, so the combination is easy to fall apart.

[0007] 4. The combination effect of the spliced ​​building block components of this structure and the rotating parts (such as wheels, gears, pulleys, sprockets, etc.) is as follows: Figure 2 As shown, when the wheel 22' is connected to the spliced ​​building block component 10', it is necessary to use an adapter 21' on the outer surface of the spliced ​​building block component 10' for switching. The contact length between the protrusion 211' of the adapter 21' and the groove 101' of the spliced ​​building block component 10' is limited, so this combination is easy to fall apart. Summary of the invention

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] See also Figure 3 , Figure 4 and Figure 5 One of the splicing building block assemblies created by the present invention: a six-sided splicing building block component 10, comprising a square body having a frame 13 and six combination surfaces, one combination surface of the body is defined as a first combination surface 11, and the other combination surfaces are defined as second combination surfaces 12, and the first combination surface 11 has two solid protrusions; one of the protrusions is defined as a first protrusion 111, and the other protrusion is defined as a second protrusion 112; see Figure 5 The first protrusion 111 and the second protrusion 112 each include a matching rib (1111, 1121), and a reinforcing rib 1112 is vertically fixed to the center of both sides of the matching rib (1111, 1121); Figure 5As shown, the cross-sectional shapes of the first protrusion 111 and the second protrusion 112 are the same, the cross-sectional length directions of the two matching ribs (1111, 1121) are perpendicular to each other, and the width of the matching ribs (1111, 1121) is slightly larger than the width of the reinforcing rib 1112; grooves are also provided on the combination surface, wherein two grooves are provided on the first combination surface 11 and are positioned as first grooves 113, and four grooves are provided on each second combination surface 12 and are defined as second grooves 122, and each of the first grooves 113 and the second grooves 122 each include two groups of matching grooves 1113 whose length directions are perpendicular to each other and can be interference-fitted with the matching ribs (1111, 1121);

[0051] The two protrusions are distributed on one diagonal line of the first combination surface 11 , the two first grooves 113 are distributed on another diagonal line of the first combination surface 11 , and the four second grooves 122 are distributed diagonally in pairs on the second combination surface 12 where they are located.

[0052] The square body is provided with three through holes of equal diameter (such as Figure 3 The two ends of each through hole respectively penetrate the two opposite combination surfaces vertically, and the through hole is located at the center of the corresponding combination surface. The three through holes intersect and penetrate each other vertically; the through hole with one end penetrating the first combination surface 11 is defined as the first revolving surface 114, and the other two through holes with both ends penetrating the second combination surface 12 are defined as the second revolving surface 121. Both ends of the first revolving surface 114 and the second revolving surface 121 are provided with an annular step, defined as an annular concave platform 115; that is, an annular concave platform 115 is provided at the through opening at both ends of each through hole.

[0053] Combination Figure 4 As shown, the depth directions of the first groove 113 and the second groove 122 are perpendicular to the combination surface, and the grooves on the three combination surfaces adjacent to the corner vertices of the same square body are perpendicularly intersected and connected to each other. Figure 4 The three grooves of the three combined surfaces adjacent to the corner vertices of the cut-away square body are a first groove 113 on the first combined surface and second grooves 122 on the other two second combined surfaces. The three grooves are vertically intersected and connected to each other, which not only saves space but also forms the bottom of each groove at the intersection, forming a depth-direction limit and bottom support for the component inserted into the groove; Figure 4 If one of the three combined surfaces next to the corner vertex indicated by A is a first combined surface, and the first combined surface adjacent to the corner vertex is a convexity, then there are only two grooves, namely, two second grooves, which intersect and communicate with each other perpendicularly; Figure 4 If the three combined surfaces beside the corner vertex indicated by B are all second combined surfaces, then the three second grooves are adjacent to the corner vertex, and the three second grooves are perpendicularly intersected and connected to each other.

[0054] The second splicing building block assembly created by the present invention: short shaft 20, Figure 6 The figure shows a structural example of a short shaft 20, which includes a rib body portion, the cross-section of the rib body portion is cross-shaped, and the rib body portion is composed of two short shaft matching ribs 21 that intersect each other perpendicularly;

[0055] Figure 7 In the example shown, the rib body portion is provided with a boss at one end thereof, which is defined as a limiting boss 22; Figure 8 In the example shown, both ends of the rib body are provided with limiting bosses 22;

[0056] The short shaft matching rib 21 of the rib body is adapted and interference fit with the matching groove 1113 of the six-sided splicing building block component 10. The matching of the short shaft 20 of different structural forms with the groove of the six-sided splicing building block component 10 can be combined into a variety of styles.

[0057] The third splicing building block component created by the present invention: T-axis 30, see Fig. 9 As shown, it consists of a matching rib portion and a stop plate 33, wherein the matching rib portion has a plurality of matching ribs 31, and the outer surfaces of all matching ribs 31 are located on a revolving surface, which is defined as a T-shaft revolving surface 32, and the stop plate 33 is located at one end of the matching rib portion of the T-shaft 30 and is coaxial with the T-shaft revolving surface 32, and the diameter of the stop plate 33 is greater than the diameter of the T-shaft revolving surface 32, thereby forming an annular shoulder.

[0058] like Fig.24 As shown, the matching ribs 31 on the matching rib portion of the T-shaft 30 can be matched with matching grooves on rotary type parts (such as wheels 40, chucks 50, gears, pulleys, sprockets, etc.).

[0059] The T-axis rotation surface 32 can be matched with the first rotation surface 114 and the second rotation surface 121 of the six-sided splicing building block component 10 .

[0060] The annular stopper formed by the stop plate 33 can sink into the concave platform 115 of the six-sided splicing building block component 10.

[0064] See also Figures 12 to 19 As shown in the figure, the schematic diagram of the mutual splicing mode of the six-sided splicing building block component 10 and the short shaft 20 created by the present invention shows that by inserting the short shaft 20 on different faces of the six-sided splicing building block component 10, the single-sided convex form of the original six-sided splicing building block component 10 can be changed into double-sided convex, three-sided convex, four-sided convex, five-sided convex and six-sided convex forms. The types of parts are greatly reduced, thereby reducing production costs.

[0065] See also Figure 20 to Figure 21 As shown, it is a schematic diagram of the mutual splicing mode of the six-sided splicing building block component 10 and the T-axis 30 created by the present invention. It can be understood that the wheel 40 can be replaced with a gear, a pulley or other rotary parts to make the combination richer.
