Magnetic plate for attracting cartridge
View Patent ↗The present invention relates to a magnetic plate for attracting cartridges. The magnetic plate comprises an upper cover, a support frame and a lower cover. The upper cover, the support frame and the lower cover are connected fixedly in order from top to bottom. The upper cover and the lower cover are engaged and form a case. The support frame is positioned within the case. Magnetic components are mounted between the support frame and the lower cover. The magnetic components comprise metal members and magnetic steel members connected fixedly to the metal members. The metal members are stuck on the bottom surface of the support frame. The metal steel members include first magnetic steel members and second magnetic steel members. The first magnetic steel members are arranged on the upper surface of the metal members and pass upwards through the support frame, and the second magnetic steel members are arranged on the lower surface of the metal members and pass through downwards through the lower cover. The N poles of the first magnetic steel members and the second magnetic steel members are arranged opposed to each other. The magnetic plate of the present invention has strong magnetic properties and thus can firmly attracting cartridges and holding the magnetic plate itself firmly on other metal surface. The area that can storage cartridges are large. The magnetic plate of the invention has simple structure, simple installation and production assembly. The magnetic plate has a small thickness and high space utilization rate.
