Self-locking connection floor

The present invention relates to a self-locking connected floor board structure. It includes floor board self-body, its one side edge is equipped with first tongue, and its another side edge is equipped with first slot mortise, under the first tongue the second slot mortise is cut, and under the described first slot mortise the second tongue is set, and the side portion of the floor board self-body over the described first tongue is the upper edge of the floor board, and under the second slot mortise its combination lip is set, and the distance between the described second plane and first plane is greater than the distance between third plane and first plane. 本发明涉及一种自锁连接的地板，包括地板本体[1]，所述的地板本体[1]的一侧边设有第一榫舌[2]，地板本体[1]的另一侧边设有第一插槽[3]，第一榫舌[2]的下方开有第二插槽[14]，所述的第一插槽[3]的下方设有第二榫舌[5]，所述的第一榫舌[2]上方的地板本体[1]的侧部为地板上边缘[12]，所述的第二插槽[14]的下方为接合唇[8]，所述的第二平面与第一平面之间的距离大于第三平面与第一平面之间的距离。由于接合唇的宽度小于第一榫舌的宽度，使得对地板上表面的切削量变小，地板的有效利用面积变大。
