Description

Technical Field

[0001] This utility model relates to components for assembling toys in intellectual development, and in particular to a cross connector for assembling toys, belonging to the field of toy technology. Background Technology

[0002] Building blocks are a common type of toy used in children's intellectual development. The components of building blocks can be stacked like building blocks, or connected using interlocking or mortise-and-tenon joints, similar to mechanical connections. Stacking components without connections results in models with poor stability and retention. Models assembled using mechanical connections are more stable, but require machining of connecting structures such as holes, slots, and rods, leading to higher mold development and manufacturing costs. Furthermore, component connections can only be made at locations with existing connecting structures, limiting the angles, positions, and fits between components during assembly. Additionally, due to factors such as the machining and molding of connecting structures, the number of connection points per unit volume is relatively small. Summary of the Invention

[0003] The purpose of this utility model is to provide a cross connector for toy assembly, which has a number of connection points.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a cross connector for toy assembly, including a connector body, the body being cross-shaped, with a blind hole in the center of the front of the cross, and blind holes also being provided on both sides of the cross edge of the center blind hole, with magnetic components installed in the blind holes.

[0005] Furthermore, the horizontal and vertical sides of the cross are of equal length, and their midpoints intersect.

[0006] Furthermore, the blind hole is a round hole.

[0007] Furthermore, a blind hole is also provided in the center of the cross-shaped back, and a magnetic component is installed in the blind hole.

[0008] Furthermore, the magnetic component includes a cylindrical outer shell that can be tightly fitted and fixed in a blind hole. The front opening of the outer shell has a shoulder with annularly distributed teeth A machined on it. An inner nesting cylinder is fitted inside the outer shell. The front end face of the inner nesting cylinder has a ring of teeth B that mate with teeth A. Both teeth A and B are inclined planes. Teeth B can rotate relative to teeth A under circumferential torque. The teeth of teeth B jump between the teeth of teeth A, and teeth B rotate along teeth A. The inner nesting cylinder and the outer shell are in a clearance fit. When teeth A and B are not engaged, the inner nesting cylinder... The inner sleeve can rotate relative to the outer shell. Multiple axial protrusions are integrally connected to the front end face of the inner sleeve. The multiple axial protrusions are evenly distributed on the circumference. The space between two adjacent protrusions can accommodate the protrusions on another inner sleeve. The rear end of the protrusion is thin and the front end is thick in the radial direction of the inner sleeve. The inner surface of the protrusion is a smooth curved surface from back to front. The cylindrical magnet is located inside the inner sleeve. The space enclosed by the protruding front end is smaller than the size of the cylindrical magnet in any direction. The size of the inner cavity of the inner sleeve is larger than the size of the magnet in any direction. The magnet can be freely rotated in the inner cavity of the inner sleeve.

[0009] Furthermore, the inner front end of the inner sleeve has a radially protruding inner ring, the inner diameter of which is larger than the diameter of the cylindrical magnet.

[0010] The positive and beneficial technical effects of this utility model are as follows: the cross connector has many connection points, is easy to process, is easy to standardize and manufacture, has good stability between components, and can be spliced ​​between components at multiple angles. 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: main body; 2: front center blind hole; 3: blind hole A; 4: blind hole B; 5: blind hole C; 6: blind hole D; 7: back center blind hole; 8: outer shell; 9: inner nested cylinder; 10: convex tooth; 11: curved surface; 12: convex ring; 13: shoulder; 14: face tooth B; 15: face tooth A.

[0017] As shown in the attached figure, a cross-shaped connector for assembling toys includes a connector body 1, which is cross-shaped with equal lengths of horizontal and vertical sides and their midpoints intersecting. A blind hole is provided at the center of the front side of the cross, as shown in Figure 2. Blind holes are also provided on both sides of the cross side of the blind hole at the center of the front side. Blind holes A and B are on one side of the cross, and blind holes C and D are on the other side of the cross. A blind hole is also provided at the center of the back side of the cross, as shown in Figure 7. The blind holes are round holes, and a magnetic component is installed in the blind holes.

[0018] In this embodiment, the magnetic component can adopt the following structure: the magnetic component includes a cylindrical shell 8 and a cylindrical magnet. The two ends of the cylindrical magnet are N and S poles, respectively, and both ends have chamfers. The cylindrical magnet is an existing commodity that can be purchased or customized, and is not shown in the figure.

[0019] The outer shell 8 can be tightly fitted and fixed in the blind hole. A shoulder 13 is located at the front opening of the outer shell, and annularly distributed teeth A15 are machined on the shoulder. An inner nesting cylinder 8 is fitted inside the outer shell 1. The front end face of the inner nesting cylinder has a ring of teeth B14 that mate with the teeth A15. The inner nesting cylinder and the outer shell are in a clearance fit. Both sides of teeth A and B are inclined surfaces. Teeth B can rotate relative to teeth A under circumferential torque. During rotation, the teeth of teeth B jump between the teeth of teeth A. Teeth B rotates along teeth A. Multiple axial protrusions 10 are integrally connected to the front end face of the inner nesting cylinder. After the inner nesting cylinder is inserted into the outer shell, the protrusions protrude from the shoulder. The protrusions are in a cantilever state. In this embodiment, there are 6 protrusions, and the multiple axial protrusions are evenly distributed on the circumference. The space between two adjacent protrusions can accommodate another... A tooth on an inner nested cylinder has a thinner rear end and a thicker front end in the radial direction of the inner nested cylinder. The inner surface of the tooth is a smooth curved surface from back to front, as shown in Figure 11. A cylindrical magnet is located inside the inner nested cylinder. The diameter of the circle formed by the front ends of the tooth is less than or equal to the diameter and height of the cylindrical magnet, meaning the cylindrical magnet cannot escape from the opening circle formed by the tooth. In actual design, the minimum diameter of the end chamfer can be slightly smaller than the diameter of the circle formed by the tooth. In this way, the chamfered front end can come out from the opening under the attraction of the magnet, allowing the magnets on the two connectors to be attracted together. The size of the inner cavity of the inner nested cylinder is larger than the size of the magnet in any direction. The magnet can freely flip (rotate) inside the inner cavity of the inner nested cylinder. There is a radially protruding inner ring at the front end of the inner ring sleeve. The inner diameter of the protruding ring is larger than the diameter of the cylindrical magnet.

[0020] This magnetic assembly contains a magnet that can rotate 360 ​​degrees (i.e., any angle). When the magnets on different connectors come close, the protrusions on one component insert between the protrusions on the other component. Due to the repulsion of like poles and the attraction of unlike poles, the magnets automatically rotate to form two different poles and can then be attracted together (when the two magnets are attracted, the chamfered part of the magnet protrudes from the opening formed by the protrusions, and the two magnet surfaces can be attracted 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 protrusions on the components are subjected to circumferential torque, causing the teeth of tooth B to jump between the teeth of tooth A, thus achieving angle adjustment. After adjustment, teeth B and teeth A mesh together again to maintain the relative angle positioning, resulting in good stability.

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.
