Description

Technical Field

[0001] The utility model relates to the technical field of toys, and more specifically, to a connecting piece, a magnetic patch, a magnetic patch assembly and a splicing toy. Background Art

[0002] Magnetic patches are a kind of educational magnetic puzzle toy for children to play. Magnetic patches belong to building block puzzle toys, but compared with traditional building blocks made of hard materials, magnetic patches are more flexible. Specifically, magnetic patches are composed of flexible blocks and multiple connectors.

[0003] The connector in a traditional magnetic patch usually includes an upper shell, a lower shell and a magnetic attraction component. The upper shell is fixedly connected to one side of the flexible block in the magnetic patch by ultrasonic welding or adhesive, and the lower shell is also fixedly connected to the other side of the flexible block by ultrasonic welding or adhesive, and the magnetic attraction component is arranged between the upper shell and the lower shell. This connector is fixedly connected to the flexible block and cannot be disassembled. Therefore, when the flexible block or connector in a magnetic patch is damaged, the entire magnetic patch will be scrapped and cannot be used anymore. More specifically, the connector on one of the flexible blocks cannot be matched with another flexible block of the same or different shape to form a new magnetic patch, which leads to a waste of connector resources and a high overall manufacturing cost of the magnetic patch. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a connector, a magnetic patch, a magnetic patch assembly and a puzzle toy, which can separate the connector from the flexible block, reduce the overall manufacturing cost of the magnetic patch, and increase the service life of the connector. The embodiments of the present application are mainly achieved through the following technical solutions:

[0005] A first aspect of an embodiment of the present application provides a connecting piece, including:

[0006] An upper shell, a lower shell and a magnetic attraction member, wherein the lower shell is provided with a protruding structure, the protruding structure is provided with a first mounting hole and at least one first clamping portion, the magnetic attraction member is accommodated in the first mounting hole, the upper shell is provided with a second mounting hole and at least one second clamping portion, the protruding structure is accommodated in the second mounting hole, and each of the second clamping portions forms a limiting groove with the inner side wall of the upper shell;

[0007] When the upper shell and the lower shell are connected, each of the first clamping parts is accommodated in the corresponding limiting groove, and each of the first clamping parts is clamped and connected with the corresponding second clamping part to prevent the upper shell from being separated from the lower shell;

[0008] When the upper shell and the lower shell are disassembled, the upper shell is rotated in the horizontal direction until each first clamping portion is completely moved from the limiting groove to the second mounting hole, so that the protruding structure can be disengaged from the second mounting hole, and the upper shell is completely disengaged from the lower shell.

[0009] By adopting the above technical solution, the connector provided by the embodiment of the present application is connected by the upper shell and the lower shell in a snap-fit ​​connection mode, and this snap-fit ​​connection mode enables the upper shell, the lower shell and the flexible block to be disassembled. Specifically, the present application is to set a protruding structure with at least one first snap-fit ​​portion on the lower shell, and to set a second mounting hole and at least one second snap-fit ​​portion on the upper shell, the protruding structure is accommodated in the second mounting hole, and each second snap-fit ​​portion forms a limiting groove with the inner side wall of the upper shell. When it is necessary to install a complete connector, the protruding structure of the lower shell is extended into the second mounting hole, and then the upper shell is rotated in the horizontal direction until each first snap-fit ​​portion is completely accommodated in the limiting groove, and the connector is installed. When the connector needs to be disassembled, the upper shell is rotated in the horizontal direction until each first snap-fit ​​portion is completely moved from the limiting groove to the second mounting hole, so that the protruding structure can be separated from the second mounting hole, and the upper shell is completely separated from the lower shell, and the connector is decomposed. Compared with the non-detachable prior art, the embodiment of the present application can achieve the separation of the connector and the flexible block, so that the connector can flow between multiple flexible blocks of the same or different shapes, thereby improving the reusability of the connector, thereby increasing the service life of the connector and reducing the overall manufacturing cost of the magnetic patch.

[0010] Since the connecting piece of the embodiment of the present application is a detachable structure, the magnetic patch can break away from the shape constraints of the magnetic patch of the original manufacturer and achieve a more personalized combination of magnetic components.

[0011] According to an embodiment of the present application, a plurality of anti-slip protrusions are provided on the protrusion structure, and the anti-slip protrusions are distributed around the first mounting hole.

[0012] The above technical solution can not only prevent slipping between two adjacent connecting members, but also fix the connection angle between the two connecting members.

[0013] According to an embodiment of the present application, a plurality of anti-slip grooves are further provided on the lower shell body, and each anti-slip groove is used to accommodate a corresponding anti-slip protrusion in another connecting member.

[0014] By adopting the above technical solution, the gap between two adjacent connecting pieces caused by the anti-slip protrusions can be reduced, thereby improving the aesthetics of the overall shape formed by connecting a plurality of connecting pieces.

[0015] According to an embodiment of the present application, each of the anti-slip protrusions and each of the anti-slip grooves are configured to be hemispherical or wedge-shaped.

[0016] According to an embodiment of the present application, the lower shell is further provided with a plurality of positioning posts, a plurality of connecting parts and a plurality of limiting holes, one end of each connecting part is connected to the corresponding positioning post, and the other end is connected to the side wall of the corresponding limiting hole, and each connecting part is accommodated in the corresponding limiting hole;

[0020] According to an embodiment of the present application, a plurality of through holes are further provided on the lower shell body, and each through hole is located below the corresponding first clamping portion.

[0021] By adopting the above technical solution, the user can observe through the multiple through holes whether the first clamping portion is completely accommodated in the corresponding limiting groove, thereby improving the success rate of the installation of the connecting piece.

[0022] According to an embodiment of the present application, a disassembly direction marking portion is also provided on the upper shell.
