Description

Technical Field

[0001] This utility model relates to toy connectors, and more particularly to a variable angle four-way connector for toy assembly, belonging to the technical field of intellectual development equipment. Background Technology

[0002] In model building for intellectual development, using multiple connectors for interlocking is a common connection method. During model building, connectors with connection structures in multiple directions have better expandability and extension performance. In actual model building, there are many cases where variable angle connections are required. Existing variable angle connections are generally achieved by rotating the original parts. However, the angle needs to be positioned after rotation. If the positioning is not good, the stability of the built model will be very poor. The intervals (divisions) between existing rotation angles are generally large, and the positioning after rotation is not good or the positioning mechanism is relatively complex. Summary of the Invention

[0003] The purpose of this utility model is to provide a variable angle four-way connector for easy toy assembly.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A variable angle four-way connector for toy building, including right-angle piece A and right-angle piece B. One or both right-angle sides of right-angle piece A and right-angle piece B are cylindrical sides. The outer periphery of the cylindrical side is circular, or a polygon inscribed in a circle, or a polygon with a circumscribed circle. A notch is provided at the right-angle portion of right-angle piece A and right-angle piece B. When right-angle piece A and right-angle piece B have two cylindrical sides, the root of one of the cylindrical sides is completely exposed on the notch. When right-angle piece A... When right-angle piece B has a cylindrical edge, the root of the corresponding cylindrical edge is exposed on the notch. The notches of right-angle pieces A and B are joined together. End teeth are integrally set or fixedly connected to the cylindrical edges of right-angle pieces A and B with the root exposed on the notch. The end teeth are coaxial with the cylindrical edge. The end teeth on right-angle pieces A and B mesh with each other. Right-angle pieces A and B are connected by elastic elements or magnets. The direction of the force generated by the elastic elements or magnets is along the axial direction of the cylindrical edges of right-angle pieces A and B with the root exposed on the notch.

[0005] Furthermore, the right-angle piece A and right-angle piece B are the same.

[0006] Furthermore, both right-angled parts A and B have cylindrical sides.

[0007] Furthermore, the end teeth are directly machined on the end face of the cylindrical edge.

[0008] Furthermore, the structure connecting right-angle piece A and right-angle piece B via an elastic element is as follows: a T-shaped hole structure is integrally connected inside the cylindrical side, and a bolt is inserted through the T-shaped hole; a spring is inserted through the bolt, and a nut is screwed onto the bolt, with the nut pressing on the spring, and the other end of the spring abutting against the bottom of the T-shaped hole.

[0009] Furthermore, the structure connecting right-angle piece A and right-angle piece B via an elastic element is as follows: a T-shaped hole structure is integrally connected inside the cylindrical side, and a bolt is inserted through the T-shaped hole; an elastic washer is inserted through the bolt, and a nut is screwed onto the bolt, with the nut pressing against the elastic washer, and the other end of the elastic washer abutting against the bottom of the T-shaped hole.

[0010] The positive and beneficial technical effects of this utility model are as follows: This four-way connector can be deformed at multiple angles. Due to the use of a meshing tooth structure, the division of the angle change can be very small, and the positioning is reliable after the angle change is completed, which meets the needs of existing model building. The specific implementation method will be described in detail. Attached Figure Description

[0015] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0016] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: Right-angled piece A; 2: Cylindrical side A; 3: Right-angled piece B; 4: Cylindrical side B; 5: End tooth; 6: T-shaped hole A; 7: T-shaped hole B; 8: Bolt; 9: Elastic pad; 10: Nut; 11: Notch.

[0017] As shown in the attached figure, a variable-angle four-way connector for toy assembly includes right-angle piece A1 and right-angle piece B2. One or both right-angle sides of right-angle pieces A and B are cylindrical. In this embodiment, both right-angle sides of right-angle pieces A and B are cylindrical. The outer periphery of the cylindrical side is circular, or a polygon inscribed in a circle, or a polygon with a circumscribed circle. In this embodiment, the outer periphery of the cylindrical side is circular. It is easy to understand that this technical solution can still be implemented when the outer periphery of the cylindrical side is a regular hexagonal prism, a regular square prism, or similar shape. A notch 11 is provided at the right-angle portion of right-angle pieces A and B. When right-angle pieces A and B have two cylindrical sides, the root of one cylindrical side is completely exposed on the notch. When right-angle pieces A and B have one cylindrical side, the root of the corresponding cylindrical side is... In the attached diagram, cylindrical edges A and B are exposed in the notch. The notch portions of right-angle pieces A and B are joined together. End teeth 5 are integrally or fixedly connected to the cylindrical edges of right-angle pieces A and B exposed in the notch. The end teeth are coaxial with the cylindrical edges and mesh with each other. Right-angle pieces A and B are connected by elastic elements or magnets. The direction of the force generated by the elastic elements or magnets is along the axial direction of the cylindrical edges of right-angle pieces A and B exposed in the notch.

[0018] In this embodiment, even if the right-angled parts A and B are the same, or if the right-angled parts A and B are not completely the same, this technical solution can still be achieved.

[0019] In this embodiment, the end teeth are directly machined on the end face of the cylindrical edge. It is easy to understand that the end teeth may not be located on the end face of the cylindrical edge. For example, a coaxial cylinder integral with the cylindrical edge can be set inside the cylindrical edge, and the end teeth can be located on the end face of the cylinder.

[0020] Figure 4 The illustration shows an embodiment of a connection using elastic elements. Right-angle pieces A and B are connected by elastic elements as follows: a T-shaped hole structure is integrally connected within the cylindrical side. In the figure, the T-shaped hole structure in right-angle piece A is shown as T-shaped hole A6; the T-shaped hole structure in right-angle piece B is shown as T-shaped hole B7; a bolt 8 passes through the T-shaped hole; an elastic washer 9 passes through the bolt; a nut 10 is screwed onto the bolt, pressing against the elastic washer, and the other end of the elastic washer abuts against the bottom of the T-shaped hole. Replacing the elastic washer with a spring achieves the same function.

[0021] When using a magnet for connection, simply fix (or tightly fit) the magnet to the bottom of the T-hole. The two magnets on the right-angled piece have opposite polarities to provide attraction.

[0022] When changing the angle of this connector, simply pull the cylindrical side A and cylindrical side B slightly in opposite directions to disengage the two end teeth and then rotate to adjust the angle. After the angle is adjusted, the end teeth mesh and achieve positioning under the action of elasticity or suction.

[0023] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
