Description
Technical field
The invention belongs to a kind of toy, particularly a kind of safety magnetic toy.
Background technology
Magnetic toy is as a kind of block toy, and children can be assembled into various composition models with three-dimensional structure according to the hobby and the imagination of oneself, thus be considered to help to improve children's imagination and creativity open the intelligence love toys.
As depicted in figs. 1 and 2, traditional magnetic toy generally is made up of a plurality of bar magnets 1 and a plurality of solid magnetic conductive metal ball 2, wherein each bar magnet 1 by a metallic rod 12, place these metallic rod 12 each ends magnet 11, be placed in the body 13 made by synthetic resin on the metallic rod 12 and outer surface and the edge of magnet 11 outer end S formed.In bar magnet 1, magnet 11 is generally made discoid, places metallic rod 12 each end, makes bar magnet 1 to play a role as the cylindrical magnet with circular section, and an end of bar magnet 1 is the N utmost point like this, and its other end is the S utmost point.
By each magnetic conductive metal ball 2, a plurality of bar magnets 1 couple together, thereby can form various composition models with three-dimensional structure.
Above-mentioned magnet generally adopts the stronger rare earth neodymium of magnetic property (Nd) class material, be that sintered NdFeB constitutes mostly, magnet all adopts axial charging, as Fig. 3, shown in Fig. 4 and Fig. 5-a and Fig. 5-b, every magnet has the N that is distributed in its two ends, S the two poles of the earth, the magnetic line of force 23 from the N utmost point to the S utmost point all can form stronger magnetic field around magnet axial and side, very little magnet just can satisfy the needed magnetic force of block toy, thereby magnet volume is very little in the existing magnetic toy, the solid magnetic conductive metal sphere volume that matches with it is also very little, cost can be saved like this, the space of storage toy can be saved again.
Yet, little magnet and magnetic conductive metal ball, child's mistake easily eats it.Since the magnet that adopts axial charging its axially and around the side all can form more by force, magnetic field far away, in case magnet and magnetic conductive metal ball are eaten, because of magnet to magnetic conductive metal ball (perhaps another piece magnet) than strong suction, magnet not only can hold near magnetic conductive metal ball (or another magnet), and can move to it every magnetic conductive metal ball far away (or another magnet) by suction phase, may clamp the intestines wall like this, and cause intestines distortion obstruction even intestines wall to be bored a hole and life-threatening danger.Moreover, above-mentioned magnet is distributed in its axial magnetic field, axially can produce powerful magnetic force at it, and it moves from trend with certain acceleration can to force magnetic conductive metal ball at a distance, thereby also may cause the harm that crushes human body (particularly finger).If two magnets are relative with different the two poles of the earth respectively, the magnetic force of Chan Shenging will be powerful especially between the two, cause the harm that crushes human body (particularly finger) also may be bigger, in case two magnets are eaten, its intestines that cause distortion be stopped up even intestines wall perforation and life-threatening danger is also bigger.
If increase the volume of magnet and solid magnetic conductive metal ball, to prevent the child it is eaten, not only cost can increase, and the magnetic of the magnet of increase also can strengthen thereupon, and it causes the above-mentioned harm that crushes human body also can increase thereupon.Thereby existing magnetic toy can't solve the safety problem that it brings because of adopting the magnet of axial charging.
In addition, the magnetic force that magnet produced in the magnetic toy, as long as can hold the magnetic conductive metal ball, make it be fixed on the end of bar magnet and do not fall down, just can realize the purpose of assembly unit magnetic toy, but its Distribution of Magnetic Field of magnet that axially magnetizes in the existing magnetic toy is around magnet, the coverage of its magnetic force can be radiated from the far place of magnet, the magnetic line of force is not effectively utilized, and not only easily brings above-mentioned safety problem, has caused the waste in magnetic energy source yet.Moreover, owing to adopt axial charging, when being fixed to the barred body two ends, two magnets must consider the polarity of magnetic pole, make troubles to production and processing.And, adopt Sintered NdFeB magnet in the existing magnetic toy magnet, magnet is too thick, if directly being bonded in the barred body end comes off easily, thereby generally adopt the method for injection moulding, perhaps the body that coverage of synthetic resin or polyurethane constitute outside magnet and barred body is fixed on the barred body end with magnet, the range of choice of so not only processed complex, and barred body material is also very limited.
Therefore, solve existing magnetic toy and adopt the problem of safety problem, cost height, processed complex and the waste of magnetic energy source that axial charging brings because of its magnet, it is very necessary making improvements.
Summary of the invention
The technical problem that the embodiment of the invention will solve is to provide a kind of safety magnetic toy, is intended to solve existing magnetic toy adopts safety problem, cost height, processed complex and the waste of magnetic energy source that axial charging brings because of its magnet problem.
The embodiment of the invention is to realize like this, a kind of safety magnetic toy, comprise bar magnet and magnetic conductive metal ball, wherein, bar magnet comprises barred body and the magnet that is fixed in each end of barred body, and magnet has a surface of magnetizing of adopting single face multipole magnetization mode to magnetize, and a groove is caved in on the surface of magnetizing, groove can satisfy magnetic conductive metal ball portion surface and enter in the groove, and is that line contact or face contact when contact with the surface of magnetizing.
The safety magnetic toy that technique scheme provides, different with the existing magnetic toy that magnet adopts the axial charging mode to magnetize, its magnet adopts the single face multipole magnetization, pole pitch 〉=0.5mm, inner surface number of magnet poles 〉=2, the magnetic circuit that forms is shorter, magnetic field is mainly concentrated on magnetize in the surperficial in-plant grooved area, be equivalent in groove, set up one " internal magnetic field ", the Distribution of Magnetic Field surperficial in-plant zone of in groove, magnetizing, form the intensive magnetic line of force, and a little away from magnet magnetize the surface the place ahead, its magnetic field is very faint, and is then fainter in its magnetic field, side, have magnetic field hardly, the magnetic line of force has obtained effective utilization.Also because magnetic field only is distributed in the groove, be fully used in this zone in magnetic field, when only entering in the groove on magnetic conductive metal ball portion surface, it just is subjected to stronger magnetic force, when its contacting with the surface line that magnetizes or face contact after can be fixed on the barred body firmly.In case leave groove, magnet faint magnetic field outside groove, it moves from trend from afar may not force the magnetic conductive metal ball, thereby has avoided bringing thus, crushes the harm of human body (particularly finger).Adopt two fast magnets of single face multipole magnetization, because a little less than the field pole of every magnet slot outside, produce suction each other hardly, even it is closely that the surface of magnetizing of two fast magnets is relative, suction between the two is also very little, thereby also avoided because of magnetic force forces two relative accelerated motions of magnet, may cause the harm that crushes human body (particularly finger).Same reason, adopt two fast magnets of single face multipole magnetization, avoided also that magnet and magnetic conductive metal spherical zone come because of the child eats by mistake, because of between the magnet or the mutual attraction between magnet and the magnetic conductive metal ball cause intestines distortion obstruction, even the intestines wall life-threatening danger of boring a hole.In addition, adopt the magnet of single face multipole magnetization, do not need to consider magnets N, S polarity, can not adorn anti-problem by polarization, so also can bring the convenience of processing.
