Self-locking connection floor

Abstract

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.

Description

technical field [0001] The present invention relates to a floor. Background technique [0002] The existing self-locking connected floor includes a floor body, a first tongue protrudes from one side of the floor body to the outside, and a first slot is recessed from the other side of the floor body to the inside , there is a second slot under the first tongue, and the upper wall or lower wall of the second slot is provided with a locking groove that is concave along the direction perpendicular to the horizontal plane, and the first slot There is a second tongue under the bottom of the second tongue, and the upper or lower surface of the second tongue is provided with a protrusion protruding in the vertical direction. The side of the floor body above the first tongue is the upper edge of the floor, so The bottom of the second slot is the engagement lip, the longitudinal plane perpendicular to the horizontal plane where the upper floor edge [12] is located is called the first...

[0002] The existing self-locking connected floor includes a floor body, a first tongue protrudes from one side of the floor body to the outside, and a first slot is recessed from the other side of the floor body to the inside , there is a second slot under the first tongue, and the upper wall or lower wall of the second slot is provided with a locking groove that is concave along the direction perpendicular to the horizontal plane, and the first slot There is a second tongue under the bottom of the second tongue, and the upper or lower surface of the second tongue is provided with a protrusion protruding in the vertical direction. The side of the floor body above the first tongue is the upper edge of the floor, so The bottom of the second slot is the engagement lip, the longitudinal plane perpendicular to the horizontal plane where the upper edge of the floor [12] is located is called the first plane, and the outer end of the first tongue [2] is located The longitudinal plane perpendicular to the horizontal plane is called the second plane, the outer end of the engaging lip is the outer end face of the engaging lip, and the longitudinal plane perpendicular to the horizontal plane where the outer end face of the engaging lip is located is called the third plane. The distance between the third plane and the first plane is greater than the distance between the second plane and the first plane, so the joint lip is very wide, which will cause the effective area of ​​the entire upper surface of the floor to be small, and the loss of the floor when processing the board is relatively large, especially When a precious decorative layer is attached to the upper surface of the floor, the floor of this structure will cause a lot of loss of the edge of the decorative layer, resulting in a substantial increase in its cost
