Description

a magnetic button

technical field

The utility model relates to a button of a leather case for a mobile phone, in particular to a magnetic button which utilizes the magnetic force of a permanent magnet to attract and close.

Background technique

Magnetic buttons are very useful in many occasions. Unlike traditional button components, the fastening and unfastening is achieved by inserting or disengaging the button from the buttonhole. The fastening of the magnetic button is achieved by having complementary or opposite magnetic It is achieved by magnetic attraction between a pair of magnetic buttons. This magnetic button arrangement can be automatically fastened when the releasable counterparts approach each other, and at the same time the coupled magnetic buttons can be simply released by pulling the buttons apart from each other. Magnetic buttons are widely used in mobile phone cases, purses, simple boxes and other containers to provide simple and convenient sealing and opening without the trouble of finding the right combination every time, but if the magnetic buttons on the market now If the magnet is small, the attraction force is small, and it is easy to fall off; if the magnet is large, the volume of the button will be large, which will increase its production cost accordingly.

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides a magnetic button with small volume, strong suction force and low cost.

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

A magnetic button, including a magnetic component, and an attraction component that can be magnetically attracted to the magnetic component, the magnetic component includes a magnet cover, a bottom plate, a permanent magnet between the magnet cover and the bottom plate, and a permanent magnet between the bottom plate and the permanent magnet metal sleeve.

In addition, further, the metal sleeve is a dish-shaped sheet, a circular through hole is opened in the center of the metal sleeve, and there is a flange on the edge of the metal sleeve, and a housing is formed between the flange of the metal sleeve and the magnet cover body. Cavities for permanent magnets.

The beneficial effects of the utility model are: the magnetic component includes a metal sleeve between the bottom plate and the permanent magnet, and after one side of the magnet is covered by the iron metal sleeve, the magnetic field of the magnet will form an open circuit, and the magnetic field of the magnet on the side that is not covered will be broken. It will be concentrated on one point, and the magnetic force will increase. After using this technology, the same effect can be achieved. The magnet of the new product is half smaller than the magnet of the old product, which solves the problem between the suction force and the volume of the magnetic button. , which saves raw materials, has low cost, and has a wide range of applications, and can be used on mobile phone cases, purses, simple boxes and other containers.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a three-dimensional split view of the utility model;

Fig. 2 is a sectional view of the magnetic component of the present invention.

Detailed ways

Referring to Fig. 1 and Fig. 2, a magnetic button includes a magnetic component 1 and a suction component 2 that can be magnetically engaged with the magnetic component. The magnetic component 1 includes a magnet cover 7, a bottom plate 9 and a Between the permanent magnet 4 and the metal sleeve 3 between the bottom plate 9 and the permanent magnet 4.

In addition, further, the metal sheath 3 is a dish-shaped sheet, the center of the metal sheath 3 has a circular through hole 5, and the edge of the metal sheath 3 has a flange 6, the flange 6 of the metal sheath 3 and the magnet cover A cavity 8 for accommodating the permanent magnet 4 is formed between the 7 bodies, and the permanent magnet 4 is an annular sheet-shaped permanent magnet with a circular through hole 13 in the center.

The suction component 2 is a circular metal sheet, one side of which has a boss 10 that can fit into the through hole 5 and the through hole 12 of the magnetic component 1 , and the other side is fixed with an installation card 11 .

The bottom plate 9 is a circular metal sheet, and one side has a boss 15 that can be fitted into the through hole 13 of the permanent magnet 4 and the circular through hole 12 of the metal sleeve 3, and the boss 15 passes through the circular through hole of the metal sleeve 3 5 and the circular through hole 13 of the permanent magnet 4 fix the metal sleeve 3 and the permanent magnet 4 on the base plate 9 to prevent sliding from causing inconvenience, and the other side is fixed with an installation card 11.

There is a circular passage 12 on the magnet cover 7, and the through hole 12 cooperates with the through hole 13 of the permanent magnet 4, so that the boss 10 of the suction assembly 2 can be easily fitted, and the magnet cover 7, Metal sleeve 3 and the fixed card 14 that bottom plate 9 clamps.

The utility model is easy to install and use. The boss 10 of the suction assembly 2 fits into the groove formed by the through hole 5 and the through hole 12 on the magnetic assembly 1, which prevents the separation of the magnetic assembly 1 and the suction assembly 2 due to sliding. The lower edge of the magnet cover 7 has Fix the card 14, install the permanent magnet 4, the metal sleeve 3 and the bottom plate 9 in the magnet cover 7, press the fixed card 14 toward the center of the circle, fix the parts in the magnet cover 7 to form a whole, and then use the installation card 11 Fixing the suction assembly 2 and the magnetic assembly 1 on the main body or the cover can realize the button function of sealing and opening.

According to the principle of the magnet, when one side of the magnet is encased by iron metal, the magnetic field of the magnet will form an open circuit, and the magnetism of the unencased side of the magnet will be concentrated on one point, and the magnetic force will be increased.

According to this principle, the utility model is provided with a metal sleeve 3 between the bottom plate 9 of the magnetic force assembly 1 and the permanent magnet 4 . The magnetic field of the magnet forms an open circuit due to the effect of the metal sleeve 3, and the magnetism of the side that is not covered is concentrated on one point, that is, in the groove formed by the through hole 5 and the through hole 12, and the protrusion on the suction assembly 2 The table 10 fits in the groove, and serves the purpose of joining the two parts of the object together.
