Magnet structure for educational toy

Abstract

The utility model discloses a magnet structure for an educational toy, which comprises a body, and the center of the body is provided with a shaft hole; and a clamping groove which is matched with an external part to be buckled and fixed is concavely arranged on the peripheral side surface of the body. According to the educational toy, the clamping groove is formed in the side face of the periphery of the body in the concave mode, the body and an external part can be matched, buckled and fixed through the clamping groove, loosening caused by thermal expansion and cold contraction is avoided, the risk that the magnet is prone to loosening from the external part is effectively eradicated, and therefore the educational toy is better in use stability and brings convenience to use.

Description

Technical Field

[0001] The utility model relates to the field of toy accessories, in particular to a magnet structure used for educational toys. Background Art

[0002] Currently, some educational toys with rotating mechanisms often have magnets installed inside. These magnets are usually ring-shaped and tightly mounted on external parts, which are usually made of plastic. Because plastic materials are prone to thermal expansion and contraction, the thermal expansion and contraction coefficient is relatively large, which can easily cause the magnets to come loose, making the educational toys unable to function properly and causing inconvenience. Therefore, it is necessary to improve the current magnets. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a magnet structure for educational toys, which can effectively solve the problem that the existing magnets are easily loosened from educational toys.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A magnet structure for educational toys comprises a body with an axial hole at the center; and a recessed slot for fastening with external parts on the outer peripheral side of the body.

[0006] Preferably, the shaft hole is a circular hole.

[0007] Preferably, the outer contour of the body is circular.

[0008] Preferably, the slot is annular and is located in the middle of the outer peripheral side of the body.

[0009] Preferably, the cross section of the slot is arc-shaped.

[0010] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0011] By providing a recessed card slot on the outer side of the main body, the card slot can be used to cooperate with the external parts to fix them, and will not become loose due to thermal expansion and contraction, effectively eliminating the risk of the magnet easily loosening from the external parts, thereby making the use of the educational toy more stable and bringing convenience to use.

[0017] 12. Card slot DETAILED DESCRIPTION

[0018] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the present utility model, including a main body 10.

[0019] The main body 10 has an axial hole 11 at its center. The outer side surface of the main body 10 is concavely provided with a slot 12 for engaging with an external part and fastening the same.

[0020] In this embodiment, the outer contour of the body 10 is circular, with a diameter of 6 mm and a height of 3.4 mm. The axial hole 11 is a circular hole with a diameter of 1.5 mm, extending through the upper and lower end surfaces of the body 10. The retaining groove 12 is annular and located in the middle of the outer circumference of the body 10. The cross-section of the retaining groove 12 is arc-shaped, with a width of 0.8 mm, a maximum depth of 0.2 mm, and a radius of 0.5 mm.

[0021] The method of using this embodiment is described in detail as follows:

[0022] The product is fixed to the external part by inserting it into a mold, so that the slot 12 is locked and engaged with the external part, thereby effectively preventing the product from falling off the external part. Alternatively, the product can be embedded in the mounting hole of the external part, so that the slot 12 is locked and engaged with the protrusion in the mounting hole, thereby effectively preventing the product from falling off the external part.

[0023] The design focus of the utility model is that a card slot is concavely provided on the outer peripheral side of the main body, and the card slot can be used to cooperate with the external parts for fastening and fixing, so that the magnet will not become loose due to thermal expansion and contraction, and the risk of the magnet being easily loosened from the external parts is effectively eliminated, thereby making the use stability of the educational toy better and bringing convenience to use.

[0024] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
