Abstract
The invention discloses a cover plate structure which comprises a first cover plate and a second cover plate. The second cover plate is provided with a groove which contains the first cover plate, the first cover plate is in pivotal connection with the second cover plate, a first end portion of the first cover plate is provided with a protruding portion which is provided with a first plane and a second plane, and the first plane and the second plane form an inclined angle. The inner wall, relative to the protruding portion, of the groove is a third plane, and the third plane is respectively matched with the first plane and the second plane. When the third plane is matched with the first plane, the groove is opened by the first cover plate; and when the third plane is matched with the second plane, the groove is covered by the first cover plate. According to the cover plate structure, the lever principle is used, acting force exists in the protruding portion position, and thus the first cover plate has no stable middle staying position and can be just stayed on an opening position or a covering position. Therefore, the opening position and the covering position the first cover plate are fixed, parts in the groove are convenient to install and disassemble, production efficiency is improved, and cost is reduced.
