Abstract

The utility model discloses a magnetic button, which comprises a magnetic component, and a pull-in component pulled-in with the magnetic component in a magnetism way, wherein, the magnetic component comprises a magnetic body cover, a bottom plate and a permanent magnet positioned between the magnetic body cover and the bottom plate, and a metal cover positioned between the bottom plate and the permanent magnet. After one face of the magnetic body is hitched by the iron metal cover, the magnetic field of the magnetic body can form circuit brake, the magnetism of other face of the magnetic body which is not hitched can be centralized into one point, thus, the magnetic force can be increased, after the technology is utilized, the identical effect is reached, the magnetic body of the utility model is less than half of the traditional magnetic body, the raw material is saved, the cost is low, the application scope is wide, and the utility model can be used for mobile telephone covers, bags, other simple boxes and other containers.

Description

A kind of Magnetic button

Technical field

The utility model relates to a kind of Leather cover for handset class button, particularly a kind of Magnetic button that utilizes the adhesive of permanent magnet magnetic force.

Background technology

Magnetic button is very useful in many occasions, it is unlike traditional button assembly, fastening and untiing by button being filled in or being deviate from button hole and realize, the fastening of Magnetic button is to realize by the magnetic attracting force that has between complementation or the mutually diamagnetic pair of magnetic button.The fastening automatically when the counter pair that can untie is closer to each other of this Magnetic button device, and the Magnetic button of coupling meanwhile can be by drawing back button and simply untie each other.Magnetic button is widely used in cell-phone cover, and suitcase is on simple box and other containers, so that the simply and easily airtight worry that all goes for accurate combination each time of having removed from opening to be provided, if but the Magnetic button magnet on the present market is little, then the suction-combining force is little, comes off easily; Magnet is big, and then the volume of button is bigger, correspondingly can increase its production cost.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of volume little, the Magnetic button that the suction-combining force is strong, cost is low.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of Magnetic button comprises the magnetic force assembly, and can with the adhesive assembly of magnetic force assembly magnetic attracting, the magnetic force assembly comprises magnet lid, base plate and permanent magnet and the metallic sheath between base plate and permanent magnet between magnet lid and base plate.

In addition, further, described metallic sheath is a dish-shaped tablet, and the metallic sheath center has a manhole, and there is flange at the metallic sheath edge, the cavity of a ccontaining permanent magnet of composition between the flange of metallic sheath and the magnet lid body.

The beneficial effects of the utility model are: the magnetic force assembly includes the metallic sheath between base plate and the permanent magnet, after the one side of magnet is entangled by iron metallic sheath, the magnetic field of magnet will form opens circuit, the magnetic of that face magnet that does not entangle just is concentrated on the point, magnetic force will increase, after utilizing this technology, reach same effect, new-type product magnet is more half as large than old-fashioned product magnet, has well solved the problem between the suction-combining force and the Magnetic button volume, it saves raw material, cost is low, and the scope of application is wide, can be used in cell-phone cover, suitcase is on simple box and other containers.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a three-dimensional broken away view of the present utility model;

Fig. 2 is the profile of the utility model magnetic force assembly.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of Magnetic button, comprise magnetic force assembly 1, and can with the adhesive assembly 2 of magnetic force assembly magnetic attracting, magnetic force assembly 1 comprises magnet lid 7, base plate 9 and permanent magnet 4 and the metallic sheath 3 between base plate 9 and permanent magnet 4 between magnet lid 7 and base plate 9.

In addition, further, described metallic sheath 3 is dish-shaped tablets, metallic sheath 3 centers have a manhole 5, and there is flange 6 at metallic sheath 3 edges, the flange 6 of metallic sheath 3 and magnet cover the cavity 8 of forming a ccontaining permanent magnet 4 between 7 bodies, and permanent magnet 4 is annular slice permanent magnets of a center band manhole 13.

Adhesive assembly 2 is circular metal plates, and the one side has a boss 10 that can be embedded in through hole 5 on the magnetic force assembly 1 and the through hole 12, and opposite side is fixed with installs card 11.

Base plate 9 is circular metal plates, the one side has a boss 15 that can be embedded in the manhole 12 of the through hole 13 of permanent magnet 4 and metallic sheath 3, boss 15 is fixed on metallic sheath 3 and permanent magnet 4 on the base plate 9 by the manhole 5 of metallic sheath 3 and the manhole 13 of permanent magnet 4, preventing to slide makes troubles, and opposite side is fixed with installs card 11.

Have one circular logically 12 on the magnet lid 7, this through hole 12 cooperates with the through hole 13 of permanent magnet 4, makes the boss 10 of adhesive assembly 2 can be chimeric like a cork, the fixedly card 14 that its lower limb has can cover magnet 7, metallic sheath 3 and base plate 9 tighten.

The utility model is installed and use and convenient.The boss 10 of adhesive assembly 2 is embedded in the groove that is made of through hole 5 and through hole 12 on the magnetic force assembly 1, prevented to make magnetic force assembly 1 and adhesive assembly 2 separately owing to sliding, magnet covers 7 lower limbs fixedly card 14, after being installed in permanent magnet 4, metallic sheath 3 and base plate 9 in the magnet lid 7, push fixedly card 14 to center of circle direction, parts are fixed in the magnet lid 7, form an integral body, card 11 utilize to be installed then adhesive assembly 2 and magnetic force assembly 1 are fixed on main part or the cap, just can realize airtight with the button effect of opening.

According to the principle of magnet, after the one side of magnet was entangled by iron metal, the magnetic field of magnet will form opened circuit, and the magnetic of that face magnet that does not entangle just is concentrated on the point, will increase magnetic force.

The utility model is according to this principle, is provided with a metallic sheath 3 between the base plate 9 of magnetic force assembly 1 and permanent magnet 4.The magnetic field of magnet is owing to the effect formation of metallic sheath 3 is opened circuit, the magnetic of that face magnet that does not entangle concentrates on the point, promptly concentrate in the groove that through hole 5 and through hole 12 constitute, the boss 10 on the adhesive assembly 2 is embedded in this groove, plays the purpose that the two parts with object combine.
