Magnetic attracting button

Abstract

The invention discloses a magnetic attracting button. The magnetic attracting button comprises a first button piece and a second button piece; a first magnetic portion which is cylindrical is convexlyarranged on a fastening surface of the first button piece, and a first limiting portion is arranged on the side peripheral edge of the first magnetic portion; a circular cavity is formed in a fastening surface of the second button piece, and is provided with a front opening and a side opening which communicate with each other and can allow the first magnetic portion to extent; an arc spring platewith a notch is assembled in the circular cavity; the arc spring plate is mounted at the position of the inner side of the front opening in a facing manner; a notch of the arc spring plate faces theside opening; the width of the side opening is slightly greater than the notch of the arc spring plate; a second magnetic portion is arranged on the bottom of the circular cavity and corresponds to the surrounding region of the arc spring plate; and the arc spring plate is provided with a second limiting portion, and the first limiting portion and the second limiting portion can be mutually limited and positioned. According to the scheme, the magnetic attracting button is simple and novel in structural design, and is convenient and labor-saving to operate, and by a creative front and side typeopening and closing mode, the magnetic attracting button is quite favorable for blind operation and is suitable for blind persons.

Description

technical field [0001] The invention relates to the technical field of buckles, in particular to a magnetic button. Background technique [0002] Buckles are more and more widely used in daily life, such as luggage, clothing, safety protective gear and other objects. Buckles are usually installed on two separate parts to realize the detachable connection of the two parts effect. At present, there are various types of fasteners, among which magnetic fasteners are a relatively common form, such as magnetic buttons, which are often used on clothing, decorations, bags and other objects. The existing focus on magnetic buttons is generally the problem of magnetic attraction. If the magnetic attraction is too large or too small, it will affect the performance of the buckle. When it is too large, it is not conducive to the opening and closing operation. [0003] At present, in order to overcome the above-mentioned problem that the magnetic attraction force is difficult to grasp, ...

Problems solved by technology

The existing focus on magnetic buttons is generally the problem of magnetic attraction. If the magnetic attraction is too large or too small, it will affect the performance of the buckle. When it is too large, it is not conducive to the opening and closing operation

[0003] At present, in order to overcome the above-mentioned problem that the magnetic attraction is difficult to grasp, one way of thinking is to design the magnetic attraction slightly smaller, and use another clamping structure to assist the cooperation.

For example, refer to the schoolbag cover buckle disclosed in the existing document 201280041618, which is mechanically locked by engaging the concave and convex parts that cooperate with each other, and needs sliding parts to cooperate and control, that is, the mechanical locking and unlocking is controlled by pressing the sliding parts. The operation is relatively strenuous and cumbersome, and the operability is even worse for the blind

Furthermore, the existing magnetic buttons usually have a positive opening and closing structure and a single opening and closing form. Specifically, the two buckling parts of the magnetic button perform buckling and opening actions along the side-by-side direction corresponding to the buckling state of the two magnetic bodies. And it is the only way of opening and closing. On some objects, the single positive opening and closing structure will bring limitations and inconvenience, and the operation of the single positive opening and closing structure requires a certain degree of alignment accuracy. For the blind, this This type of alignment is still relatively difficult, and it needs to be tried repeatedly in the operation, and the practicability is insufficient.
