Abstract

A magnetic frame mechanism including an outer frame, first drop center wheels, first brackets, a permanent magnet block. The outer frame includes a face plate, a first side plate, and a second side plate. The first side plate and the second side plate are vertically fixed on two ends of the face plate, respectively. The permanent magnet block is sandwiched between the first side plate and the second side plate. The first side plate and the second side plate include guide structures, and the guide structures include first guide rails. The first drop center wheels are fixed on the inner side of the face plate via the first brackets, respectively. The platform mechanism includes a platform plate, four magnetic travelling wheels, four second brackets, a second guide rail disposed on the surface of the platform plate, and a tension spring.

Claims
