Description

Technical Field

[0001] This utility model relates to toys, and more particularly to a four-way elbow connector in a splicing toy, belonging to the field of toy technology. Background Technology

[0002] In building blocks, models made from simple blocks using connecting structures (such as hole-and-rod connections or mortise and tenon connections) are more stable, easier to design diverse building components, and have more model transformation capabilities, which is more conducive to the intellectual development of young children. However, components using connecting structures need to have connecting structures such as holes and slots on the components (connectors). The connection between the components and other components often requires the use of rods or other insertable parts. In addition, in order to make the model sturdy, the connecting structure and the rod are generally designed with locking and unlocking mechanisms. This leads to the complexity of the connecting parts. If there are multiple or multi-directional connecting structures on the connecting parts, it will be even more complicated, and it is also difficult to miniaturize the connecting parts. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the current assembly toy connectors and to provide a four-way elbow connector for toy assembly.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a four-way elbow connector in toy assembly, including a long cylinder, two short cylinders integrally arranged at 90 degrees apart on the cylindrical surface of the long cylinder, and assembly holes are provided at both ends of the long cylinder and the end faces of the short cylinders. Magnet mounting components are fixedly or tightly fitted in the assembly holes, and cylindrical magnets are installed in the magnet mounting components.

[0005] Furthermore, the assembly hole is a blind hole.

[0006] Furthermore, the two short cylinders are located in the middle of the length of the long cylinder.

[0007] The positive and beneficial technical effects of this utility model are as follows: This connector can be connected to other components with magnet mounting and connecting elements with magnets by mutual attraction. The connection structure design is relatively easy, and it has multiple and multi-directional connection structure points. The stability after connection is relatively good, and the direction adjustment is simple and easy. The specific implementation method will be described in detail. Attached Figure Description

[0012] 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.

[0013] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: long cylinder; 2: short cylinder A; 3: short cylinder B; 4: assembly hole; 5: outer sleeve; 6: inner sleeve; 7: meshing tooth; 8: curved surface; 9: shoulder; 10: face tooth A; 11: face tooth B.

[0014] As shown in the attached diagram, the four-way elbow connector in the toy assembly includes a long cylinder 1. Two short cylinders are integrally arranged at 90-degree intervals on the cylindrical surface of the long cylinder. The two short cylinders are located in the middle of the length direction of the long cylinder. In the figure, the two short cylinders are short cylinder A2 and short cylinder B3. Assembly holes 4 are opened at both ends of the long cylinder and on the end faces of the short cylinders. The assembly holes are blind holes. Magnet mounting components are fixed or tightly fitted in the assembly holes. Cylindrical magnets are installed in the magnet mounting components.

[0015] In this application, the magnet mounting component may be the magnet mounting component disclosed in CN104066489B (Magnet mounting component and magnetic toys including the same).

[0016] In addition to the aforementioned magnet mounting components, this utility model also provides a relatively simple magnet mounting component, as shown in the attached figure. Figure 2 , Figure 3 , Figure 4As shown, the magnet mounting components include an outer sleeve 5 and an inner sleeve 6. Both the outer and inner sleeves are cylindrical structures with a central hole, which is also circular. A shoulder 9 is integrally formed at the front of the central hole of the outer sleeve. The rear end face of the shoulder 9 has a tooth A. The front end face of the inner sleeve has a tooth B that can mesh with the tooth A. Both sides of the tooth A and the tooth B are inclined surfaces. The tooth B can rotate relative to the tooth A under circumferential torsion. During rotation, the teeth of the tooth B jump between the teeth of the tooth A. Face tooth B rotates along face tooth A. The inner sleeve has six forward-extending meshing teeth 7 integrally formed around its central hole. The inner surface of these teeth extends radially inward from the rear front, and is a smooth curved surface to prevent the magnet from getting stuck. After the meshing teeth of the two inner sleeves are staggered, the cylindrical magnet is located within the central hole cavity of the inner sleeve. The cylindrical magnet can rotate freely within the central hole cavity. The opening formed by the six meshing teeth is less than or equal to the diameter and height of the magnet, meaning the magnet will not escape from the inner sleeve. The inner sleeve is fitted with a clearance fit within the outer sleeve, with face teeth A and B facing each other. The outer sleeve is tightly fitted into a blind hole, and the bottom of the blind hole limits the movement of the cylindrical magnet. The cylindrical magnet is a commercially available product with chamfered ends. The meshing teeth are cantilevered and can be made of plastic. The circle formed by the front ends of the meshing teeth is less than or equal to the diameter and height of the cylindrical magnet. In actual design, the minimum diameter of the chamfer at the end can be slightly smaller than the diameter of the circle formed by the protrusion. This allows the chamfered front end to protrude from the opening under the attraction of the magnet, enabling the magnets on the two connectors to be attracted together.

[0017] After the magnet mounting components are installed in the blind hole, the magnet is located in the hollow cavity of the inner sleeve. The magnet can rotate 360 ​​degrees (i.e., any angle). When the magnet assemblies on different connectors approach each other, the meshing teeth on one component (the meshing teeth on the connector) insert between the meshing teeth on the other component. Due to the repulsion of like poles and the attraction of unlike poles, the magnet automatically rotates to two different poles and then attracts together. After attraction, tooth B is forced to adhere to tooth A. Due to the attraction of the magnets, the angle between the two components can be relatively positioned. When the angle needs to be adjusted, the two components are rotated relative to each other. The meshing teeth on the components are subjected to circumferential torque, causing the teeth of tooth B to jump between the teeth of tooth A, thereby achieving angle adjustment. After adjustment, teeth B and teeth A mesh together again, so that the angle of the two components (connectors) is relatively positioned, resulting in good stability.

[0018] 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.
