Abstract
A clamp mounting structure of electromagnets and a cover plate is disclosed, comprising magnet yokes and cover casings. L-shaped pins are molded in the bottom end of each magnet yoke. An L-shaped elastic buckle, facing an opposite direction with respect to the pins, is molded in the bottom end of each covering casing. First and second via holes matched with the pins and the elastic buckles are molded on the cover plate. When each electromagnet is mounted, the electromagnet is inclined forwards for a certain angle to enable the L-shaped pins of the magnet yoke to insert into the first via holes and then the electromagnet is pushed forwards to enable the pins to hook the bottom face of the cover plate; at the same time, the elastic buckle of the cover casing is moved to the place of the second via hole and pressed downwards so as to insert into the second via hole and during the insertion process, the elastic buckle is extruded by the hole wall of the second via hole and deformed elastically; and after the elastic buckle penetrates through the second via hole, the elastic buckle recovers elastically and forms a reversed buckling structure together with the bottom face of the cover plate. When each electromagnet is disassembled, the elastic buckle is pressed and deformed elastically so as to disconnect from the bottom face of the cover plate and thus the electromagnet can be taken off conveniently.
