Detailed Description
The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 6, a magnetic type automatic cover closing structure includes an upper cover 20 and a base 10, where the upper cover 20 can be turned over relative to the base 10 to open or close the cover, a mounting groove 101 is provided on the base 10, a combining portion 202 is provided on the upper cover 20 corresponding to the mounting groove 101, the combining portion 202 can be accommodated in the mounting groove 101 when the cover is closed, the combining portion 202 includes a rotating shaft 201, a sliding groove 102 for the rotating shaft 201 to slide is provided on a side wall of the mounting groove 101, the rotating shaft 201 is inserted into the sliding groove 102, the upper cover 20 and the base 10 are rotatably connected through the rotating shaft 201, a first magnetic member 203 is provided on the combining portion 202, a second magnetic member 103 with opposite magnetism to the first magnetic member 203 is provided on the base 10, and when the cover is closed, the two magnetic members are attracted to quickly and automatically buckle the upper cover 20 and the base 10.
Through setting up first magnetic part 203 and second magnetic part 103, when closing the lid action, utilize the positive and negative principle of inhaling mutually of first magnetic part 203 and second magnetic part 103 to make upper cover 20 and base 10 fast lock, first magnetic part 203 and second magnetic part 103 can adopt multiple mode to fix in upper cover 20 or base 10, for example gluing, joint, inlay or adopt screw lock solid etc. the mounting means of first magnetic part 203 and second magnetic part 103 is simple, easy to operate, is favorable to improving production efficiency.
Preferably, the number of the mounting grooves 101 is two, the two mounting grooves 101 are respectively distributed at the left and right ends of the rear end of the base 10, and the coupling portion 202 of the upper cover 20 is also adaptively set to be two, so that the opening or closing motion can be more stable. The rotating shaft 201 and the combining part 202 are integrally formed, and can also be two separate parts. The rotating shaft 201 extends towards the inner side of the upper cover 20, and correspondingly, the sliding groove 102 on the mounting groove 101 is arranged on the inner side wall of the mounting groove 101. The sliding groove 102 is substantially dumbbell-shaped, the width of the middle part of the sliding groove 102 is slightly smaller than the aperture of the two ends of the sliding groove 102, the aperture of the two ends of the sliding groove 102 is matched with the diameter of the rotating shaft 201, the two ends of the sliding groove 102 form a first clamping position and a second clamping position, and the rotating shaft 201 is located in the first clamping position or the second clamping position when the cover is opened or closed.
