A floorboard connecting structure, comprising a floorboard unit and the floorboard connecting base, and a floorboard connector having a transversal part and a longitudinal part, wherein the floorboard unit is provided with a connecting post clamped into an installation groove, an end of the connecting post is provided with a hooking part;
- the floorboard connecting base, comprising:
- a base body;
- a convex part located at an end of an upper surface of the base body;
- and
- a limiting part located at the upper surface of the base body and spaced from the convex part to form the installation groove for inserting the floorboard unit;
- wherein
- a free end of the limiting part is bent in a direction towards the convex part to form a step block for limiting the floorboard unit, and the step block is clamped and matched with the hooking part;
- wherein the step block has a triangular structure, and the step block has a first sloping face, the first sloping face being a plane or a convex arc face;
- wherein the hooking part is of an approximate trapezoidal structure, and the hooking part is provided with an introduction sloping face for auxiliary clamping, the introduction sloping face is a plane or a convex arc face, and a slope of the introduction sloping face is greater than a slope of the first sloping face;
- wherein the limiting part is provided with a U-shaped groove in a vertical direction, a notch of the U-shaped groove gradually expands outward, a lower surface of the base body is provided with a first groove, and the first groove is located below the convex part, and a bottom of the first groove is arc-shaped;
- when the connecting post of the floorboard unit is dropped into the installation groove, the step block and the convex part can open to both sides, and an elastic deformation space of the convex part can be ensured when the first groove is squeezed;
- wherein a first included angle α between the step block and the limiting part is an obtuse angle, and the first included angle α is not greater than 135°;
- wherein the transversal part and the longitudinal part are perpendicular to each other and cross to form a perpendicular cross-shape, four curved parts are formed at the cross positions of the transversal part and the longitudinal part, and each of the curved parts is provided with a first right-angle groove, and the first right-angle groove separates the floorboard connector to form a barrier wall located at a middle portion and four first insertion blocks of the right-angled structure;
- the floorboard unit is rectangular, with a second right-angle groove provided at least one right angle of the rectangle;
- when the floorboard connector is spliced with the floorboard unit, the connecting post of the floorboard unit is inserted into the first right-angle groove of the floorboard connector, and the first insertion block of the floorboard connector is inserted into the second right-angle groove of the floorboard unit.
