Description

Technical Field

[0001] This utility model relates to connecting elements for assembly toys, and more particularly to a triangular prism connecting element for assembly toys, belonging to the field of toy technology. Background Technology

[0002] Triangular prism components commonly used in toy assembly are generally found in building block toys. Triangular prisms with isosceles right triangles or equilateral triangles as their bases are common. This is because it is difficult to design holes or rods for connection on the surface of a triangular prism. Specifically, the holes generally need to have a certain depth to ensure the stability and firmness of the connection. If through holes are used, interference between the connected parts can easily occur during the connection. Therefore, the volume of the prism needs to be large enough, which is difficult to achieve in smaller toy connectors. If a locking and unlocking structure is to be used between the connectors, the difficulty is even greater. Therefore, how to design a better connection structure for this type of connector is a problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in existing triangular prism connecting elements and to provide a triangular prism connecting element for assembly toys.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A triangular prism connecting element in a building block toy includes a triangular prism body. Assembly holes are provided on three circumferential surfaces of the triangular prism body. All assembly holes are blind holes. A magnet mounting cavity assembly is fixedly installed or tightly fitted into the blind holes. A cylindrical magnet is accommodated in the magnet mounting cavity assembly. The magnet mounting cavity assembly includes an outer sleeve and an inner sleeve. Both the outer sleeve and the inner sleeve are circular pieces with a central circular cavity and a circular outer perimeter. A shoulder is integrally formed at the front of the central circular cavity of the outer sleeve. A tooth a is provided on the rear end face of the shoulder. A tooth b that meshes with tooth a is provided on the front end face of the inner sleeve. Both sides of tooth a and tooth b are inclined surfaces. Under circumferential torsion, tooth b can be relatively... When face tooth a rotates, the teeth of face tooth b jump between the teeth of face tooth a. Face tooth b rotates along face tooth a. Multiple integrally set axially extending meshing teeth are evenly distributed around the circular central cavity on the front end face of the inner sleeve. After the meshing teeth on the two inner sleeves are staggered, they can be inserted into the two adjacent meshing teeth of the other. The inner surface of the meshing teeth is a curved surface that extends radially inward from back to front. The diameter of the port circle formed by multiple meshing teeth is less than or equal to the diameter and height of the cylindrical magnet. The size of the circular central cavity of the inner sleeve is larger than the size of the cylindrical magnet in any direction. The cylindrical magnet can be rotated 360 degrees in the circular central cavity of the inner sleeve. The meshing teeth of the inner sleeve pass through the shoulder and are fitted into the outer sleeve. The inner sleeve is fitted into the circular central cavity of the outer sleeve with a clearance fit. Face tooth a and face tooth b face to face.

[0005] Furthermore, mounting holes are provided on both the bottom and top surfaces of the triangular prism, and magnet mounting cavity components are installed in the mounting holes.

[0006] Furthermore, the base of the triangular prism is an equilateral triangle or an isosceles right triangle.

[0007] The positive and beneficial technical effects of this utility model are as follows: the connecting element can be conveniently set with a connecting structure on the circumferential surface. When splicing, the magnets on the two magnet mounting cavity components with cylindrical magnets installed can attract each other to form a relatively stable connecting structure. Moreover, the angle can be maintained and adjusted to multiple angles. The specific implementation method will be described in detail. 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: triangular prism body; 2: mounting hole on the prism surface; 3: mounting hole on the top surface; 4: outer fitting; 5: inner fitting; 6: meshing tooth; 7: curved surface; 8: face tooth a; 9: face tooth b; 10: shoulder.

[0013] In this utility model, the cylindrical magnet is an existing commodity. The cylindrical magnet has chamfers at both ends, is readily available in the market, and its size can be customized. The cylindrical magnet is not shown in the figure and will not be described in detail here.

[0014] As shown in the attached figure, a triangular prism connecting element in a building block toy includes a triangular prism body 1. The base of the triangular prism is an equilateral triangle or an isosceles right triangle. Assembly holes are provided on all three circumferential surfaces of the triangular prism body, as well as on the bottom and top surfaces. In the figure, 2 shows the assembly hole on the prism surface, and 3 shows the assembly hole on the top surface. All assembly holes are blind holes, in which a magnet mounting cavity assembly is fixedly or tightly fitted. A cylindrical magnet is housed within the magnet mounting cavity assembly. The magnet mounting cavity assembly includes an outer sleeve 4 and an inner sleeve 5. Both the outer and inner sleeves are circular pieces with a central circular cavity and a circular outer perimeter. A shoulder 10 is integrally formed at the front of the circular cavity of the outer sleeve. The rear end face of the shoulder 10 has face teeth a8, and the front end face of the inner sleeve has face teeth b9 that can mesh with face teeth a. Face teeth a and face teeth b9... Both sides are inclined surfaces. Face tooth b can rotate relative to face tooth a under circumferential torsion. During rotation, the teeth of face tooth b jump between the teeth of face tooth a. Face tooth b rotates along face tooth a. Multiple integrally set axially extending meshing teeth 6 are evenly distributed around the circular central cavity on the front end face of the inner sleeve. After the meshing teeth on the two inner sleeves are staggered, they can be inserted into the two adjacent meshing teeth of the other. The inner surface of the meshing teeth is a curved surface 7 that extends radially inward from back to front. The port size formed by multiple meshing teeth is less than or equal to the diameter and height of the cylindrical magnet. The magnet cannot flow out from the opening formed by multiple meshing teeth. The size of the circular central cavity of the inner sleeve is larger than the size of the cylindrical magnet in any direction. The cylindrical magnet can be rotated 360 degrees in the circular central cavity of the inner sleeve. The meshing teeth of the inner sleeve pass through the shoulder and are fitted into the outer sleeve. The inner sleeve is fitted into the circular central cavity of the outer sleeve with clearance fit. Face tooth a and face tooth b face to face.

[0015] The meshing teeth are cantilevered and can be made of plastic. The diameter of 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 meshing teeth. This way, under the attraction of the magnet, the chamfered front end can protrude from the opening, allowing the magnets on the two connectors to be attracted together.

[0016] In this connecting element, a cylindrical magnet is inserted into the magnet mounting cavity assembly and then installed into a blind hole. The bottom of the blind hole limits the magnet's position. The cylindrical magnet is located in the hollow cavity of the inner sleeve and can rotate 360 ​​degrees (i.e., any angle). When the magnet assemblies on different connecting parts approach each other, the meshing teeth on one element insert between the meshing teeth on the other element. Due to the repulsion of like poles and the attraction of unlike poles, the magnets automatically rotate to form two different poles and then attract each other. After attraction, tooth b is forced to adhere to tooth a, and the angle between the two elements can be relatively positioned. Due to the attraction of the magnets, when the angle needs to be adjusted, the two elements (connecting elements) are rotated relative to each other. The meshing teeth on the elements 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 tooth a mesh together again, so that the angle of the two elements (connecting parts) is relatively positioned.

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.
