Description

Technical Field

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

[0002] In building blocks, cylindrical (disc) connectors are a common component. Many cylindrical connectors have connection structures on their end faces and circumferences, usually circular insertion holes. A round rod is inserted into these insertion holes to extend the assembled model. The applicant has also disclosed such components in Chinese patents, such as CN219595848U and CN208426657U. In order to achieve insertion from multiple directions, the insertion holes of these toys must have a certain depth to ensure the stability of the connection. This makes it difficult to miniaturize these components. Moreover, in order to achieve a certain degree of firmness after insertion, locking and unlocking mechanisms are generally required, which makes the manufacturing process more complicated. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems existing in current assembly toy components and to provide a cylindrical connector for assembly toys.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A cylindrical connector for a splicing toy, comprising a cylindrical body, the cylindrical body including a cylinder and a cylinder closed at both ends, multiple mounting holes are provided on the circumference of the body, and a magnetic sheet assembly is installed in the mounting holes, the magnetic sheet assembly including a cylindrical outer sleeve, a cylindrical inner sleeve, and a cylindrical magnet, the magnetic sheet assembly being tightly fitted with the mounting holes, the front part of the central hole of the outer sleeve having a convex inner flange, the inner surface of the flange being machined with a first tooth, the inner sleeve being fitted inside the outer sleeve, the central hole size of the inner sleeve being larger than the size of the cylindrical magnet in any direction, the front end of the inner sleeve... The surface is machined with a second tooth that meshes with the first tooth. Both sides of the first and second teeth are inclined surfaces. The second tooth can rotate relative to the first tooth under circumferential torque. When rotating, the second tooth jumps between the first and second teeth. The second tooth rotates along the first tooth. Multiple limiting teeth are integrally connected to the front end surface around the central hole of the inner sleeve. The limiting teeth of the two inner sleeves can be inserted into the space between the limiting teeth of the other after they are staggered. The inner surface of the limiting teeth is a curved surface that extends inward from back to front. The opening formed by the front ends of the multiple limiting teeth is less than or equal to the diameter and height of the cylindrical magnet. A limiting cover is connected to the rear end of the outer sleeve.

[0005] Furthermore, the main body has four mounting holes on its circumferential surface, which are located at the same height and are evenly distributed in the circumferential direction.

[0006] Furthermore, the cylindrical body is a cylinder closed at both ends, and mounting holes are provided on both the upper and lower end faces of the cylinder, in which magnetic sheet assemblies are installed.

[0007] The positive and beneficial technical effects of this utility model are as follows: This cylindrical connector has a magnetic sheet assembly, which can be adsorbed and connected with elements having the same magnetic sheet assembly. The connection structure is simple, the connecting elements are easy to miniaturize, and the stability after connection is relatively easy to maintain under the action of magnetic force. It can also be conveniently adjusted at multiple angles. Attached Figure Description

[0011] 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.

[0012] 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: mounting hole on the end face; 3: mounting hole on the circumferential surface; 4: outer sleeve; 5: retaining edge; 6: first tooth; 7: inner sleeve; 8: second tooth; 9: limiting tooth; 10: curved surface; 11: limiting protrusion; 12: back cover; 13: elastic retaining edge.

[0013] As shown in the attached figures, a cylindrical connector for a building block toy includes a cylindrical body 1. The cylindrical body comprises a cylinder and a closed cylinder at both ends. Multiple mounting holes are formed on the circumferential surface of the body. In this embodiment, the cylindrical body is a closed cylinder at both ends, and mounting holes are formed on both the upper and lower end faces of the cylinder. Figure 2 shows the mounting holes on the end faces. Four mounting holes are formed on the circumferential surface of the body, located at the same height and evenly distributed circumferentially. Figure 3 shows the mounting holes on the circumferential surface, and magnetic sheet assemblies are installed within these mounting holes.

[0014] The magnetic sheet assembly includes a cylindrical outer sleeve 4, a cylindrical inner sleeve 7, and a cylindrical magnet. The cylindrical magnet has chamfered ends. Cylindrical magnets are readily available commercially and can also be custom-made to the required dimensions. The magnetic sheet assembly is tightly fitted to the mounting holes. The outer sleeve 4 has a convex flange 5 at the front of its central hole. A first tooth 6 is machined on the inner surface (i.e., the rear end face) of the flange. The inner sleeve 7 is fitted inside the outer sleeve. The central hole size of the inner sleeve is larger than the size of the cylindrical magnet in any direction. The cylindrical magnet can... The inner sleeve can be rotated in any direction within its central cavity. A second tooth 8, meshing with the first tooth, is machined on the front end face of the inner sleeve. Both sides of the first and second teeth are inclined surfaces. Under circumferential torque, the second tooth can rotate relative to the first tooth. During rotation, the second tooth jumps between the first and second teeth, rotating along the first tooth. Multiple limiting teeth 9 are integrally connected to the front end face around the central hole of the inner sleeve. After the inner sleeve is inserted into the outer sleeve, the limiting teeth protrude from the flange of the outer sleeve. The limiting teeth of two inner sleeves can be inserted after being staggered. The space between the limiting teeth, the inner surface of the limiting teeth is a curved surface 10 extending inward from back to front, and the opening formed by the front ends of multiple limiting teeth is less than or equal to the diameter and height of the cylindrical magnet, so that the cylindrical magnet will not escape from the opening. The limiting teeth are in a cantilever state, and the limiting teeth can be made of plastic. The diameter of the circle formed by the front ends of the limiting 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 of the magnet can be slightly smaller than the diameter of the circle formed by the limiting teeth, so that the magnet... Under the action of suction, the chamfered front end can come out from the opening, which can make the magnets on the two connectors attract together. A limiting cover 12 is connected to the rear end of the outer cover. In this embodiment, the rear cover is cylindrical, and the end of the cylindrical circumference has an elastic retaining edge (because the end of the elastic retaining edge is suspended and the rear cover is made of plastic, it naturally produces elasticity). There is a limiting protrusion 12 on the outer circumference of the outer cover. After the rear end of the outer cover is inserted, the elastic retaining edge is engaged with the limiting protrusion. Preferably, the elastic retaining edge is multi-segmented with gaps between the segments, which is more conducive to installation.

[0015] This magnetic assembly contains a magnet that can rotate 360 ​​degrees (i.e., any angle). When the magnet assemblies on different connectors approach each other, the limiting teeth on one component (connector) insert between the limiting teeth on the other connector. 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 comes out from the opening formed by the limiting teeth, and the two magnet surfaces can be attracted together). After attraction, the second tooth surface is pressed against the first tooth surface. Due to the attraction of the magnets, the angle between the two connectors can be relatively positioned. When the angle needs to be adjusted, the two components are rotated relative to each other. The limiting teeth on the components are subjected to circumferential torque, which causes the teeth of the second tooth surface to jump between the teeth of the first tooth surface, thereby achieving angle adjustment. After adjustment, the second tooth surface and the first tooth surface mesh together again to maintain the relative angle.

[0016] 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.
