Lower floor board of system without screws

Abstract

The invention provides a lower floor board of a system without screws, and relates to the technical field of floor board connecting parts. The lower floor board of the system without the screws comprises a net bottom which is wholly in a square structure and is used for supporting the floor boards, wherein the net bottom comprises battens which are located around the net bottom and are used for forming a square net bottom frame, a plurality of longitudinal connecting bones and horizontal connecting bones are arranged longitudinally and horizontally among the battens in integration, the longitudinal connecting bones and the horizontal connecting bones connect the battens located around the net bottom together to form the net bottom, the longitudinal connecting bones and the horizontal connecting bones are vertically intersected, a plurality of floor board installation regions with consistent shapes and areas are arranged between the longitudinal connecting bones and the horizontal connecting bones, neck regions used for clamping the floor boards are formed by stretching upward the upper surface of intersection positions of the longitudinal connecting bones and the horizontal connecting bones, dovetail grooves used for connecting the net bottom are formed in the external side walls of two adjacent battens which form the net bottom, and dovetail joints matched with the dovetail grooves are arranged on the external side walls of the other two adjacent battens. The lower floor board of the system without the screws has the advantages of being stable and reliable due to direct connection between the floor boards and the net bottom, and free of screw fixation. Horizontal connection and longitudinal connection can both be achieved between the floor boards and the net bottom, and the screw connection does not exist between the floor boards and the net bottom.
