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.

First claim

What is claimed is:

1. A device, comprising:
a magnetic frame mechanism;
a platform mechanism; and
a slider mechanism;

wherein:
the magnetic frame mechanism comprises an outer frame, first drop center wheels, first brackets, a permanent magnet block;
the outer frame comprises 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 comprise guide structures, and the guide structures comprise first guide rails;
the first drop center wheels are fixed on an inner side of the face plate via the first brackets, respectively;
the platform mechanism comprises a platform plate, four magnetic travelling wheels, four second brackets, a second guide rail disposed on a surface of the platform plate, and a tension spring;
two ends of the platform plate comprise guide grooves, and the guide grooves correspond to the first guide rails so that the platform plate is capable of moving along the first guide rails of the first side plate and the second side plate;
the first guide rails each comprises a spring stop above the platform plate and a limit plate disposed below the platform plate;
the tension spring is disposed between the spring stop and the platform plate;
the platform plate is supported by the four magnetic travelling wheels via the four second brackets;
the slider mechanism comprises a trough slider, a pull bar, second drop center wheels, and third brackets;
the trough slider comprises a bottom slideway, a side slideway, a convex sliding plate disposed in the side slideway, a pressure spring, upper horizontal rails, slanted rails, and lower horizontal rails; each slanted rail connects one upper horizontal rail and one lower horizontal rail to form a rail group;
the pressure spring is fixed on one end of the convex sliding plate, and the convex sliding plate butts against the second side plate via the pressure spring;
the first side plate comprises a through hole allowing the pull bar to pass through; the convex sliding plate is disposed on one end of the trough slider, and the other end of the trough slider is connected to the pull bar passing through the through hole of the second side plate;
a plurality of rail groups is continuously disposed on the trough slider, and each rail group corresponds to one first drop center wheel;
the second drop center wheels are connected to the trough slider via the third brackets; the second drop center wheels correspond to the second guide rail disposed on the surface of the platform plate; and
the platform plate comprises a round hole, the permanent magnet block comprises a cylindrical touch rod, the bottom slideway comprises a recess, and the cylindrical touch rod passes through the round hole of the platform plate and extends into the recess of the bottom slideway of the trough slider.
