Technical Field

[0001] The utility model relates to the technical field of building toys, and particularly to a toy building component. Background Art

[0002] Building block toys are one of the favorite toys of children. Children can build various shapes they want through spatial imagination, thereby expanding their thinking. The plug-in ball toy is one of such puzzle building toys. The existing Chinese patent CN214260666U discloses a universal splicing ball toy, in which a number of splicing holes of the same size are arranged at equal distances in the horizontal and vertical positions and the circumferential position on the sphere, and a limiting part and a fastening part structure are also arranged in the splicing holes, which can realize splicing more shapes, improve the stability of splicing, and make the splicing more firm.

[0003] Although the limiting part and the fastening part structure can make the splicing more firm, they also increase the difficulty of disassembly. Children players with little strength cannot easily disassemble it, and its practicability is poor. Moreover, this splicing ball toy cannot be combined with other accessories to build a movable combination body, resulting in a large limitation on the types of combinable bodies that can be built and unable to further expand thinking. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a toy building component to solve the problems in the related prior art that the splicing ball toy is difficult to disassemble, resulting in poor practicability, and the types of combinable bodies that can be built are greatly limited, resulting in the inability to further expand thinking.

[0005] To achieve the foregoing purpose, the utility model provides a toy building component, including a sphere and a connecting block. A plurality of plug-in holes are opened on the sphere, and the connecting block can be plugged and matched with the plug-in holes. At least two of the plug-in holes communicate to form a through hole;

[0006] The connecting block includes a building block and a movable rod. The building block includes a main body, and at least two plug-in columns are arranged on the main body. The plug-in columns are detachably plugged and matched with the plug-in holes; the movable rod includes a movable column body, and the movable column body can movably pass through the through hole and extend out of the sphere, and the end of the movable column body is detachably plugged and matched with the plug-in hole of another sphere;

[0007] Wherein, buffer cavities for providing deformation space for the inner walls are opened at the ends of the plug-in columns and the movable column body, so as to be clamped in the plug-in holes through elastic deformation.

[0008] As a preferred solution, an arcuately transitional first clamping projection is provided along the circumferential direction on the inner wall of the insertion hole. Arcuately transitional second clamping projections are respectively provided at the end portions of the insertion post and the movable cylinder body. The second clamping projections are correspondingly provided on the outer wall of the buffer cavity, and the second clamping projections are detachably clamped with the first clamping projections.

[0009] As a preferred solution, the movable cylinder body is of a cylindrical structure, and the diameter of the cylinder is smaller than the diameter of the through hole; a convex ring extends outward from one end wall of the movable cylinder body, and the maximum diameter of the convex ring is larger than the aperture of the insertion hole, and the insertion post is provided on the other side of the convex ring opposite to the movable cylinder body.

[0010] As a preferred solution, two insertion posts are provided on the building block, and the two insertion posts are connected by a straight pipe body or a bent pipe body. The end wall diameters of the straight pipe body and the bent pipe body are both larger than the diameter of the insertion post.

[0011] As a preferred solution, more than three insertion posts are provided on the building block, and the multiple insertion posts are distributed in a cross shape on the central pipe body. The end wall diameters of the central pipe body connected to the insertion posts are all larger than the diameter of the insertion post.

[0012] As a preferred solution, a through hole is further provided on the central pipe body. An arcuately transitional third clamping projection is provided along the circumferential direction on the inner wall of the through hole. The third clamping projection is detachably clamped with the second clamping projection.

[0013] As a preferred solution, the diameter of the movable cylinder body is smaller than the diameter of the third clamping projection, and the diameter of the convex ring is larger than the diameter of the through hole.

[0014] As a preferred solution, the sphere is formed by connecting two splicing blocks through an insertion structure, and six insertion holes are provided in the sphere along the XYZ axis directions, and the six insertion holes communicate to form three through holes.

A through hole adapted to the decorative bead is provided on the decorative ring. An insertion post is provided on the decorative bead. When the decorative bead is adaptively connected to the through hole, the insertion post passes through the through hole and extends out of the decorative ring.

[0016] As a preferred solution, the toy building component further includes a disassembly tool. One end of the disassembly tool is provided with a U-shaped cavity, and the two side walls of the U-shaped cavity are gradually thinned in the thickness direction; the other end of the disassembly tool is provided with a splitting piece and a splitting column connected in sequence.

The movable rod can pass through the through hole through the movable column body and extend out of the sphere, and the end of the movable column body can also be inserted and matched with the insertion hole of another sphere. Therefore, the function that the sphere can move (rotate, move, etc.) on the movable rod can be realized, and the spheres can also be connected into a whole through the end of the movable rod. Moreover, buffer cavities for providing deformation space for the inner walls are provided at the ends of the insertion column and the movable column body, so as to be elastically deformed and clamped in the insertion hole, which can not only realize firm and stable building, but also be easy to plug and unplug.

[0018] In summary, the present invention can build and assemble a plurality of spheres into a movable combination body through the building blocks and the movable rods, improving the combination effect and diversity of choices, enabling various spatial imaginations of child players to be implemented, and further expanding the thinking of children. Moreover, the present invention adopts an elastic clamping method for plugging and fixing between the connecting blocks and the spheres, which can ensure firm and stable connection and is also easy to plug and unplug and disassemble. Even child players with little strength can perform disassembly operations, thus improving the practicability of the toy building component. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0032] Please also refer to Figures 1-10 , this embodiment provides a toy building component, including a sphere 1, a connecting block 2, a decorative block 3 and a disassembly tool 4. Among them, the connecting block 2 is used to build a plurality of spheres 1 into a combined body, the decorative block 3 is connected to the sphere 1 to play a decorative role, and the disassembly tool 4 is used to assist the player in disassembling the combined body.

[0033] Among them, a plurality of insertion holes 11 are formed on the sphere 1, and the connecting block 2 and the decorative block 3 can be inserted and matched with the insertion holes 11. At least two insertion holes 11 on each sphere 1 communicate to form a through hole 12 for movably passing through the connecting block 2, so that the sphere 1 and the connecting block 2 are movably (rotatably, movably, etc.) connected.

[0034] In this embodiment, the sphere 1 is formed by connecting two splicing blocks 10 through a splicing structure. Specifically, the splicing block 10 is provided with a hemispherical arc surface and a circular bottom surface. Splicing grooves 101 and splicing posts 102 are arranged at intervals on the circular bottom surface. After the splicing grooves 101 and splicing posts 102 of the two splicing blocks 10 are aligned and pressed, a sphere 1 can be spliced. It can be understood that the above structural setting of the sphere 1 can reduce its manufacturing difficulty and save production costs. The sphere 1 is provided with six insertion holes 11 along the XYZ axis directions, and the six insertion holes 11 communicate to form three through holes 12.

[0035] In other embodiments, the sphere 1 can also be an integrally formed structure. Only a splicing groove 101 or a splicing post 102 can be provided on the circular bottom surface of a splicing block 10. It is necessary to insert and connect the splicing block 10 with the splicing groove 101 and another splicing block 10 with the splicing post 102 to realize the splicing of the sphere 1.

[0036] The connecting block 2 includes a building block 21 and a movable rod 22. The building block 21 includes a main body, and at least two insertion posts 210 are provided on the main body. The insertion posts 210 are detachably inserted and matched with the insertion holes 11, so that the building block 21 can be fixedly connected to at least two spheres 1 through the insertion posts 210. The movable rod 22 includes a movable cylinder body 221. The movable cylinder body 221 can movably pass through the through hole 12 and extend out of the sphere 1. The end of the movable cylinder body 221 is detachably inserted and matched with the insertion hole 11 of another sphere 1, so that the movable rod 22 can be movably connected to the sphere 1 through the movable cylinder body 221, and can also be fixedly connected to the sphere 1 through the end of the movable cylinder body 221.

[0037] It can be understood that in order to improve the fastening of the insertion and increase the simplicity of disassembly, buffer cavities 20 for providing deformation space for the inner walls are provided at the ends of the insertion posts 210 and the movable cylinder body 221, so that they can be clamped in the insertion holes 11 through elastic deformation.

[0038] In this embodiment, in order to further improve the fastening of the insertion, a first clamping protrusion 111 with an arc-shaped transition is provided along the circumferential direction on the inner wall of each insertion hole 11. Correspondingly, arc-shaped transition second clamping protrusions 2101 are respectively provided at the ends of the insertion posts 210 and the movable cylinder body 221. The second clamping protrusions 2101 are correspondingly arranged on the outer wall of the buffer cavity 20, and the second clamping protrusions 2101 are detachably clamped with the first clamping protrusions 111. In other embodiments, the first clamping protrusion 111 may not be provided on the inner wall of the insertion hole 11, and the ends of the insertion posts 210 and the movable cylinder body 221 may not be provided with the second clamping protrusions 2101 correspondingly.

[0039] It can be understood that the setting of the arc-shaped transition surfaces in the first clamping protrusion 111 and the second clamping protrusion 2101 is beneficial to increasing the simplicity of disassembly and assembly. When the end of the insertion post 210 or the movable cylinder body 221 is inserted into the insertion hole 11 and abuts against the first clamping protrusion 111, the second clamping protrusion 2101 abuts against the first clamping protrusion 111 through the arc-shaped transition surface and deforms under force. The player only needs to apply a small thrust to drive the end of the insertion post 210 or the movable cylinder body 221 to continue to move forward until the second clamping protrusion 2101 is separated from the first clamping protrusion 111 and opens under the action of elastic force to clamp the second clamping protrusion 2101 on the first clamping protrusion 111 to play a further fixing role. When disassembly is required, the player applies a small pulling force to the connecting block 2 to make the second clamping protrusion 2101 abut against the first clamping protrusion 111 again through the arc-shaped transition surface and deform under force until the second clamping protrusion 2101 is separated from the first clamping protrusion 111 and opens under the action of elastic force, and the end of the insertion post 210 or the movable cylinder body 221 can be withdrawn from the insertion hole 11.

[0040] In this embodiment, the main body of the building block 22 includes a straight pipe main body 211, a bent pipe main body 212, a T-shaped central pipe main body 213, and a cross-shaped central pipe main body 214. Among them, two insertion posts 210 are provided on both the straight pipe main body 211 and the bent pipe main body 212. The two insertion posts 210 protrude outward along the two ends of the straight pipe main body 211 and the bent pipe main body 212. The diameter of each insertion post 210 is smaller than the end wall diameter of the straight pipe main body 211 and the bent pipe main body 212. Three insertion posts 210 are provided on the T-shaped central pipe main body 213, and four insertion posts 210 are provided on the cross-shaped central pipe main body 214. The multiple insertion posts 210 on each central pipe main body are distributed in a cross shape on the central pipe main body, and the diameter of the end wall of each central pipe main body connected to the insertion post 210 is larger than the diameter of the insertion post 210. In other embodiments, the main body of the building block 22 may also include other shapes, such as an S-shaped pipe main body, etc.

[0041] In this embodiment, a through hole 215 is further opened on each central pipe main body. An arc-shaped third clamping protrusion 2151 is provided along the circumferential direction of the inner wall of the through hole 215. The third clamping protrusion 2151 is detachably clamped with the second clamping protrusion 2101. As Figure 4 shown, the insertion post 210 of the building block 22 can be inserted into the through hole 215 to be elastically deformed and clamped on the central pipe main body of another building block 22, thereby improving the combination effect and diversity of selection, and expanding the model selection of the combinable assembly. In other embodiments, if the insertion post 210 does not have the second clamping protrusion 2101, the inner wall of the through hole 215 may correspondingly not have the third clamping protrusion 2151.

[0042] In this embodiment, the movable column body 221 is a cylindrical structure. The diameter of the cylinder is smaller than the diameter of the through hole 12, so that the movable column body 221 can rotate relative to the sphere 1. A convex ring 222 extends outward from one end wall of the movable column body 221. The maximum diameter of the convex ring 222 is larger than the aperture of the insertion hole 11, and an insertion post 210 is provided on the other side of the convex ring 222 opposite to the movable column body 221. It can be understood that the diameter of the movable column body 221 is smaller than the diameter of the third clamping protrusion 2151, so that the movable column body 221 can rotate relative to the central pipe main body, and the diameter of the convex ring 222 is larger than the diameter of the through hole 215.

[0043] In other embodiments, the movable column body 221 can be adjusted to an arc-shaped column structure according to the shape of the through hole 12. The arc-shaped column can also pass through the through hole 12 and extend out of the sphere 1. The movable rod 22 may not be provided with the convex ring 222. At this time, both ends of the movable column body 221 can pass through the through hole 12 and extend out of the sphere 1.

[0044] In this embodiment, the decorative block 3 includes a decorative ring 31 and a decorative bead 32. A perforation 311 adapted to the decorative bead 32 is formed on the decorative ring 31. A plug post 210 is provided on the decorative bead 32, and the diameter of the end wall of the connection end between the decorative bead 32 and the plug post 210 is greater than the diameter of the plug post 210. As Figure 7 shown, when the decorative bead 32 is fitted and connected to the perforation 311, the plug post 210 passes through the perforation 311 and extends outside the decorative ring 31, so that the decorative ring 31 and the decorative bead 32 can be fixed together on the sphere 1 (or the central tube body). The decorative bead 32 can also be directly fixed to the sphere 1 or the central tube body through the plug post 210. In other embodiments, the decorative block 3 may also include decorative blocks of other shapes, such as a crown shape, etc.

[0045] It can be understood that the sphere 1, the connecting block 2 and the decorative block 3 provided in this embodiment can be randomly plugged and fixed according to the building modeling requirements of the player.

[0046] For example Figure 3 , by respectively plugging the two plug posts 210 of the straight tube body 211 into the plug holes 11 of the two spheres 1, the two spheres 1 can be fixed.

[0047] For example Figure 4 , by plugging one of the plug posts 210 of the bent tube body 212 into the through hole 215 of the cross-shaped central tube body 214, the two building blocks 21 can be fixed.

[0048] For example Figure 5 , by movably passing the movable column body 221 through the through hole 12 so that the convex ring 222 abuts against the surface of the sphere 1, and then plugging the end of the movable column body 221 (and / or the plug post 210 on one side of the convex ring 222) into the plug hole 11 of another sphere 1, one of the spheres 1 can be rotatably connected to the movable column body 221, while the other spheres 1 are fixed to the end of the movable column body 221 (and / or the plug post 210 on one side of the convex ring 222).

[0049] For example Figure 6 , by movably passing the movable column body 221 through the through hole 215 of the T-shaped central tube body 213. At this time, the convex ring 222 can abut against the outer wall of the T-shaped central tube body 213 to prevent it from detaching from the T-shaped central tube body 213. Then, by respectively plugging the plug posts 210 on the movable rod 22 and the T-shaped central tube body 213 into the plug holes 11 of the two spheres 1, the two spheres 1 can rotate relative to each other and move relative to each other through the movable rod 22 and the T-shaped central tube body 213.

[0050] It should be noted that in this embodiment, the end wall diameters of the main bodies of the building block 21 and the end diameters of the decorative beads 32 are both set to be larger than the diameter of the insertion post 210. At the same time, the maximum diameter of the convex ring 222 is set to be larger than the apertures of the insertion hole 11 and the through hole 215, so that the sphere 1, the connecting block 2 and the decorative block 3 can cooperate with the disassembly tool 4 to achieve a more convenient, fast and labor-saving disassembly.

[0051] Please also refer to Figures 8-10 , the disassembly tool 4 includes a handle 40 for holding the toy. One end of the handle 40 is provided with a U-shaped cavity 41. The two side walls of the U-shaped cavity 41 are gradually thinned in the thickness direction, so that the U-shaped cavity 41 can be inserted into the connection end between the building block 21 and the sphere 1, the connection end between the convex ring 222 and the sphere 1, and the connection end between the decorative bead 32 and the sphere 1, so that the second convex 2101 can be separated from the first convex 111, thereby making it easier to pull out the connecting block 2 and the decorative block 3.

[0052] The other end of the handle 40 is provided with a splitting piece 42 and a splitting post 43 connected in sequence. The splitting piece 42 is in a disc-shaped structure, and the splitting post 43 is in a columnar structure, wherein the width of the splitting piece 42 is larger than the diameter of the splitting post 43. The splitting piece 42 can be inserted into the gap between any two spheres 1. When rotated, it can generate a pushing and pulling force on the spheres 1 and the building block 2, so that the second convex 2101 can be separated from the first convex 111, thereby making it easier to disassemble the spheres 1 and the building block. The length of the splitting post 43 is larger than the length of the insertion hole 11 and less than or equal to the length of the through hole 12. The splitting post 43 can be inserted into the insertion hole 11 to push out the insertion post 210 or the movable cylinder body 221, so that the second convex 2101 can be separated from the first convex 111, thereby making it easier to disassemble the spheres 1, the connecting block 2 and the decorative block 3.
