Floorboard unit and floorboard connecting structure
View Patent ↗A floorboard unit and a floorboard connecting structure are disclosed in the application. The floorboard unit includes a floorboard body and a connecting post. The connecting post is located at an end edge of a lower surface of the floorboard body, and an end of the connecting post is provided with a hooking part folded in a direction toward an end of the floorboard body, and the hooking part is of an approximate trapezoidal structure, and the hooking part is provided with an introduction sloping face for auxiliary clamping. The floorboard connecting structure according to the disclosure is of a locking type, so it can be paved without glue due to a locking force, which is safe and environment-friendly. A whole structure may extend all around with change of temperature, and there will be no problems such as uplift or cracking due to the change of temperature.
1 . A floorboard connecting structure, comprising a floorboard connecting base and a floorboard unit, the floorboard unit comprising:
a floorboard body;
a connecting post located at an end edge of a lower surface of the floorboard body, an end of the connecting post being provided with a hooking part folded in a direction toward an end of the floorboard body, and the hooking part being of a trapezoidal structure, and the hooking part being provided with an introduction sloping face for auxiliary clamping:
wherein the floorboard connecting base comprises an installation groove for accommodating the connecting post and a step block for clamping and matching with the hooking part;
wherein the floorboard connection structure further provides a floorboard connector having a transversal part and a longitudinal part, the transversal part and the longitudinal part are perpendicular to each other and cross, four curved parts are formed at the cross positions of the transversal part and the longitudinal part and each of the curved part is provided with a first right-angle groove, and the first right-angle groove separates the floorboard connector to form a barrier wall and a first insertion block;
wherein the connecting post of the floorboard unit is inserted into the first right-angle groove, and the floorboard unit is provided with a second right-angle groove adapted to the first insertion block.
2 . The floorboard connecting structure according to claim 1 , wherein there are at least two joint surfaces between the connecting post and an inner wall of the installation groove, at least two joint surfaces are formed by closely matching planes and/or arc faces, and two of the at least two joint surfaces are distributed in a relative structure or an oblique diagonal structure.
3 . The floorboard connecting structure according to claim 1 , wherein the floorboard connecting base is further provided with a seam filling part.
4 . The floorboard connecting structure according to claim 1 , wherein the hooking part is bent to form a first included angle β of 90° to 135°.
5 . The floorboard connecting structure according to claim 1 , wherein the introduction sloping face is a plane or a convex arc face.
6 . The floorboard connecting structure according to claim 1 , wherein an upper surface of the floorboard body is provided with a first chamfer, and a second chamfer is provided at a first recess of the floorboard body.
7 . The floorboard connecting structure according to claim 1 , wherein the end edge of the lower surface of the floorboard body is provided with a first groove, and the connecting post is located in the first groove to divide the first groove into a first recess and a second recess.
8 . The floorboard unit according to claim 7 , wherein a bottom of the second recess is smoothly transitioned with an arc.
9 . The floorboard unit according to claim 7 , wherein a first convex arc part is provided at a side of the connecting post proximate to the second recess, and the first convex arc part and the hooking part are distributed in an oblique diagonal structure.
10 . The floorboard unit according to claim 7 , wherein a bottom of the first recess is provided with a fourth chamfer.
