Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

The invention discloses a magnetic sheet which is used as an intelligence-developing splicing type toy for children.

In the invention, the magnetic force sheet comprises a body 1, a magnet 2 is arranged on the body 1, the cross section of the magnet 2 is square, and as shown in fig. 4, one end of the cross section of the magnet 2 is an N pole and the other end of the cross section is an S pole by taking an angular line as a boundary. With this structure, four peripheral side surfaces of the magnet 2 form single magnetism, two adjacent side surfaces present S poles, and the other two adjacent side surfaces present N poles.

In a specific application, referring to fig. 5, when three magnetic sheets are spliced in a T shape, the first corner on the first magnet 2a is opposite to the first corner on the second magnet 2b, and the first corner on the third magnet 2c is opposite to the position between the first magnet 2 and the second magnet 2. As shown in the figure, when the three magnets 2 generate magnetic force, the first corner portion of the N pole on the first magnet 2a and the first corner portion of the S pole on the second magnet 2b act to attract each other, the side surface of the S pole on the third magnet 2c is opposite to the side surface of the N pole on the first magnet 2a, and the side surface of the N pole on the third magnet 2c is opposite to the side surface of the S pole on the second magnet 2b, it can be understood that the third magnet has a larger surface to act on the first magnet, and the third magnet also has a larger surface to act on the second magnet, so that the attracting force when the three magnetic pieces are spliced in a T shape is greatly improved.

Generally, the magnets are arranged in the mounting frame, so that the first magnet and the second magnet are closest to each other, the third magnet is relatively far away from the first magnet, and the third magnet is relatively far away from the second magnet.

In one embodiment, the body 1 includes a housing 3, a mounting frame 4 and a spacer, wherein the mounting frame 4 has an accommodating portion 41 and a connecting portion 42, the magnet 2 is disposed in the accommodating portion 41, the housing 3 has a mounting portion, the connecting portion 42 is connected to the mounting portion, the accommodating portion 41 is partially exposed on a surface of the housing 3, and the spacer is disposed in the housing 3.

In the invention, the position of the magnet 2 on the body 1 is relatively close to the outside by adopting the structure of the mounting frame 4, and when the two magnetic sheets are spliced, the two magnetic sheets can be firmly attracted together because the distance of the magnet 2 is close.

As shown in the figure, the housing 3 includes an upper cover 31 and a lower cover 32, and the upper cover 31 and the lower cover 32 are engaged with each other. In the description of the present embodiment, the engagement may be in a positional relationship or a connection relationship. The upper cover 31 and the lower cover 32 are usually fixed to each other by gluing or welding.

Typically, the spacer may be made of a material that is opaque to light. After the upper cover 31 and the lower cover 32 are made of different color materials, the color of the upper cover 31 and the color of the lower cover 32 do not interfere with each other. Preferably, the spacer is an aluminum-plated film, a chromium-plated film or a nickel-plated film. When the upper cover 31 and the lower cover 32 are made of light-transmitting materials, the color of the upper cover 31 and the color of the lower cover 32 are more beautiful because such spacers have a reflection effect.

Referring to fig. 3 and 4, the mounting portion includes an upper ledge 311 integral with the upper cover 31, a lower ledge 321 integral with the lower cover 32, and a positioning post 322 integral with the lower cover 32, wherein the upper ledge 311 and the lower ledge 321 are opposite. The connecting portion 42 is clamped between the upper protruding edge 311 and the lower protruding edge 321, and the connecting portion 42 is provided with a positioning hole 421 into which the positioning post 322 is inserted. Through the cooperation of reference column 322 and locating hole 421, make mounting bracket 4 and casing 3 fixed mutually, prevent that mounting bracket 4 from deviating from casing 3.

Preferably, the side surface of the positioning column 322 is connected with the side surface of the lower protruding edge 321. Because positioning post 322 has a smaller cross-section, positioning post 322 and lower flange 321 are connected together to further increase the overall strength of positioning post 322. It can be understood that, because the strength of the positioning column 322 is enhanced, the occupied size of the positioning column 322 in the width direction of the housing can be designed to be relatively small, thereby allowing more space for the spacer to be placed, and it can be understood that, the spacer can have a wider width at the position, thereby correspondingly enhancing the strength of the spacer and preventing the spacer from being broken in the assembling process or the preparation process.

In an embodiment, generally, the number of the positioning pillars 322 is 2, the number of the positioning holes 421 is 2, and the positioning pillars 322 are inserted into one of the positioning holes 421.

In one embodiment, the whole of the isolation sheet is a square annular structure, and the isolation sheet is arranged from the inner side of the mounting part. Accordingly, the inner end of the upper ledge 311 is spaced apart from the inner edge of the upper cover, and the inner end 321a of the lower ledge 321 is spaced apart from the inner edge 32a of the lower cover 32. Thereby, the spacer is fitted inside the mounting portion.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
