Description

Technical Field

[0001] The utility model relates to a toy for developing intelligence, in particular to a connection structure between a hole on a toy and a rod and a connected toy, belonging to the technical field of toys. Background Art

[0002] Toys commonly used in the development of children's intelligence are to insert rods into holes to connect and build different shapes. The holes can be polygonal, and the shape of the rods is adapted to the holes. For example, multiple connection holes are opened on the circumferential surface of a circular connecting disk, and cylindrical rods are inserted to extend and connect in different directions. This type of toy is currently widely used, and the applicant has also conducted in-depth research and development in this regard. In order to make the connection between the rods and the holes firm, the applicant has developed multiple toy plug-in structures with locking mechanisms, such as the easily detachable plug-in locking structure disclosed in CN206655580U, the plug-in toy with a self-locking mechanism disclosed in CN208493239U, etc. The circular cylindrical connection structure in the toy disclosed by the applicant in CN219595848 and the toy connector with the structure are a newly developed plug-in structure that has been widely used in toys. The plug-in structure uses a hanging piece processed on the lower cylindrical wall to achieve elasticity. The structure in CN219595848 is relatively reliable in connection and easy to release. The applicant has also adopted this structure to manufacture a large number of different products. It is found in a large number of uses that the structure has the following problems in use: when the structure is used for plugging in large-sized toys, the size of the suspension can be relatively large and will not cause problems. When it is used for toys of smaller sizes, the suspension cannot be too large, which will cause the strength of the plug-in structure to be low after connection, and it is easy to be damaged under the action of a large force, resulting in failure of the plug-in structure, especially in a low-temperature environment where the brittleness of the plastic increases. This situation is more likely to occur. In addition, the structure is used for connection between circular cylinders. When the cylinder (hole) is not circular, such as when the hole is a regular polygon, this structure is not necessarily suitable. In view of this problem, it is necessary to develop a more widely adaptable connection structure. Summary of the invention

[0018] In order to more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only for the purpose of illustrating the utility model and do not limit the scope of the utility model.

[0019] The present invention is further explained in detail in conjunction with the accompanying drawings, in which the marks are: 1: cylinder; 2: long slit A; 3: long slit B; 4: protrusion; 5: disk body; 6: rod; 7: chamfer; 8: annular groove; 9: transition point; 10: blind hole.

[0020] The smooth transition in the utility model can adopt a conical transition, an arcuate transition, or a transition combining a conical transition and an arcuate transition.

[0021] As shown in the accompanying drawings, a connection structure between a hole on a toy and a rod and a connected toy, the hole is located on the toy, in this embodiment, the rod 6 is a cylinder, the hole is a cylinder 1, the cylinder and the cylinder 1 are adapted to each other, the rod 6 is inserted into the cylinder 6 and forms a plug-in structure with the cylinder, an elastic structure is processed on the inner wall of the cylinder, the elastic structure includes two long slits opened on the cylinder wall, in the figure, the two long slits are long slit A2 and long slit B3; the long slit runs through the thickness of the cylinder wall, the two long slits do not intersect, in this embodiment, the two long slits are optimized to be parallel, there is a protrusion 4 between the two long slits, and an H shape is formed between the two long slits and the protrusion 4, the rod has a plug-in structure, the plug-in structure includes a chamfer 7 at the end of the rod, a smooth transition between the chamfer and the circumference of the rod, the minimum point of the chamfer can pass through the protrusion 4, a groove 8 is processed on the chamfered rod, and a smooth transition between the circumference of the rod at the front and rear ends of the groove 8 is made, and after the rod is inserted into the cylinder, the protrusion 4 is partially located in the groove in the radial direction. As an optimization, there are multiple identical elastic structures on the cylindrical wall. In a preferred embodiment, there are two identical elastic structures on the cylindrical wall, and the two elastic structures are 180 degrees apart. Figure 3 The structure shown has two identical elastic locking structures spaced 180 degrees apart.

[0022] The principle of the above elastic structure is: the inner wall of the whole hole is not elastic. When two long slits are opened, since the hole wall is a plastic part, the part between the two long slits becomes elastic, and the extrusion protrusion can cause it to deform elastically. Since both ends of the part between the two long slits are integrated with the main body, it has high strength and is not easy to be damaged.

[0023] A connecting toy, wherein the connecting toy has the connecting structure between the cylinder and the rod for the toy, and the connecting toy is a circular disk 5, and a plurality of holes for connecting with the rod are opened on the circumference of the disk.

The axial hole of the disk is also processed with an elastic structure.

[0024] The plate body is fixedly provided with two front and rear end faces, and the front and rear end faces of the plate body are processed with holes. In this embodiment, the holes are multiple blind holes 10, and the blind holes also have elastic structures. Figure 1 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 .

[0025] The above embodiments are described by taking a circular hole as an example. It is not difficult to understand that when the cross-section of the hole is a hole with edges and corners such as a quadrilateral, pentagon, or hexagon, the shape of the rod is adapted to the hole, and the solution of the utility model can also be implemented.

[0026] In addition, when the hole is circular, the shape of the rod is not necessarily circular, for example, it can be an inscribed hexagon of a circle. When the hole is polygonal, the rod can also be circular. For example, when the cross-section of the hole is a regular hexagon, the rod can be an inscribed circle of the regular hexagon.

[0027] After describing the implementation mode of the utility model in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application.
