Description

Waterproof, washable plastic magnetic buttons

The utility model relates to a fastening piece, in particular to a waterproof and washable magnetic button.

The general magnetic buttons currently used on objects such as boxes, bags, bags, etc. are composed of two parts: a magnetic button upper cover and a magnetic button body. The upper cover of the magnetic button is provided with fixed feet, and the main body of the magnetic button is composed of a casing, a magnet arranged in the casing, and a lower cover with fixed feet. The magnetic buttons are respectively fixed on articles such as handbags and purses that need to be frequently separated and fastened through the fixing feet arranged on the upper and lower covers, so that the covers of these articles can be opened and closed. Yet this type of convenient magnetic button has not yet been able to be applied to those objects that also need to be often separated and fastened, such as wind coats, fur coats, furs, suits and other clothing. Trace it to its cause, this is because the magnetism of general magnetic button is not strong (the magnetic field strength is about 500 gauss). In order to strengthen the magnetism, we can only increase or thicken the size of the magnet, which generally reaches 8 mm, which is inconvenient to use on clothing; second, the general magnetic button cannot be provided with a needle that fixes the button on the clothing with a thread like a general button. Third, because the magnetic button is stamped with iron sheet, although it has been electroplated or other anti-rust treatment, it still cannot avoid the occurrence of rust; fourth, the general magnetic button is not considered waterproof, so it cannot be washed with water.
