Description

Arc lock floor

technical field

The invention relates to the field of decorative building materials, in particular to a floor with arc locks.

Background technique

Wooden floor has advantages such as natural, environmental protection, attractive in appearance, luxury, etc., along with the continuous improvement of social living standard, wooden floor is more and more widely used in the places such as family, hotel. Wooden floors are generally connected by buckles. There are many types of floor buckle structures, mainly including flat buckles and lock buckles. Because the solid wood floor is easy to absorb moisture and expand during use, lose water and shrink, resulting in arching and large expansion joints. The flat button floor usually needs to be glued or nailed to fix the floor during the paving process. The paving process is very troublesome and wastes manpower. At the same time, it is easy to damage and dirty the floor during the paving process. However, after a period of use of many locking floorings currently on the market, even if the floor is firmly bonded in the initial use, due to the influence of wood shrinkage and swelling, deformation and looseness are prone to occur, and people step on the floor and there is a sound.

Chinese Invention Patent Application Publication No. CN101994382A discloses a floor board and a floor board. The board body of the floor board has opposite first and second end faces, and the first end face has a groove extending into the board body. The second end face has a tongue protruding from the end face. The upper surface of the tongue is closely attached to the upper surface of the groove, and the lower surface of the tongue is closely attached to the lower surface of the groove. In this way, the fit between the tongue and the groove is too tight during installation, and there is no buffer space for the deformation of the floor. On the contrary, in the future use of the floor, the deformation of the floor will not be released under the condition of shrinkage and swelling, which will easily cause floor deformation. Arching deformed and loose.

Detailed ways

The present invention will be described in detail below in conjunction with accompanying drawings and specific preferred embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. range is limited.

Please refer to Fig. 1 , the structure of the arc lock floor of the present invention includes a floor board body 100, the floor board body 100 is a cuboid board, and one end of the floor board body 100 is provided with a tenon 1 and a first side 10, the tenon 1 It includes a tenon 15, a second side 17 and a tenon body 12. The tenon 15 protrudes from the second side 17 and is integrally connected with the tenon body 12. The tenon 15 includes a first arc surface 14. The tenon body 12 includes a section of second arc surface 13, the first arc surface 14 is connected with the second arc surface 13 as a whole, the tenon 1 and the first side 10 enclose a hollow groove 11, The other end of the floor plate body 100 is provided with a third side 4 and a wedge 6, the wedge 6 protrudes from the third side 4, and the third side 4 and the wedge 6 enclose a slot 5 , the slot 5 includes a slot head 9 and a slot body 7, the slot head 9 is located inside the slot 5, the tenon 1 matches the slot 5, and the tenon 15 matches the slot head 9 , the tenon body 12 is matched with the groove body 7 .

Preferably, the connection between the second side 17 and the outer edge of the floor panel 100 and the connection between the third side 4 and the outer edge of the floor panel 100 are provided with a first round chamfer 3 A second circular chamfer 16 is provided on the outer edge of the tenon 15 away from the first circular arc surface 14 , and a third circular chamfer 2 is provided at the joint between the third side 4 and the groove head 9 .

Preferably, a square chamfer 8 is provided at the joint between the first side 10 and the outer edge of the floor panel 100 and the joint between the outer edge of the wedge 6 and the outer edge of the floor panel 100 .

Preferably, the radius of the first arc surface 14 is the same as the width of the portion of the tenon 15 protruding from the second side 17 .

Preferably, the height of the portion of the tenon 15 protruding from the second side 17 matches the height of the groove head 9 , and the width of the portion of the tenon 9 protruding from the second side 17 is smaller than that of the groove head 9 width.

Further, please refer to Fig. 2 and Fig. 3. When laying the arc lock floor, align the tenon 1 of one floor with the slot 5 of the other floor, and the tenon 1 takes the screw-in point 18 as the center of the circle as shown Screw in the slot 5 in the direction shown in 2, so that the tenon 15 fits with the slot head 9, and the tenon body 12 fits with the slot body 7. The tenon 1 and the slot 5 are connected together, and the two floors are also connected together.

It can be understood that since the radius of the first arc surface 14 is the same as the width of the part where the tenon 15 protrudes from the second side 17, and the first arc surface 14 is integrally connected with the second arc surface 13, the tenon 15 protrudes from the second side 17. The height of the second side 17 part matches the height of the slot head 9, and the width of the tenon 9 protruding from the second side 17 is slightly smaller than the width of the slot head 9, so the tenon 1 can be easily screwed into the slot 5 without hindrance. The state after the tenon 1 is screwed into the slot 5 is shown in Figure 3, and forms the first contact surface 20, the second contact surface 21, the third contact surface 24, the fourth contact surface 25 and the first reserved gap 19, The second reserved gap 22 and the third reserved gap 23 .

Further, after the two arc locking floors are connected together in the above manner, the first contact surface 20, the second contact surface 21, the third contact surface 24 and the fourth contact surface make the two arc locking floors horizontally Both orientation and vertical orientation are locked, and the floor connection is secure and will not come off. The first circular chamfer 3 , the second circular chamfer 16 and the third circular chamfer 2 enable the two floorboards to be connected closely without problems such as gaps or height differences. The square chamfer 8 forms a moisture-proof groove when two floors are spliced together, which facilitates the discharge of water or moisture and prevents the floor from absorbing moisture and deforming or rot. At the same time, the first reserved gap 19, the second reserved gap 22 and the third reserved gap 23 can prevent the floor from being deformed due to changes in moisture content, thereby causing the lock to become loose. When the floor is deformed, the first reserved gap 19, The second reserved gap 22 and the third reserved gap 23 can provide a buffer space for the deformation of the floor, avoiding problems such as arching and loosening of the floor due to nowhere to release the deformation of the floor, so that the tenon 1 and the groove 5 are always tightly connected , so that the floor will not loosen during use, and people will not make a sound when stepping on the floor.

Different from the prior art, the arc lock floor of the present invention is easy to install, has high installation efficiency, and the floor is firmly bonded. It will not loosen during use, and it can prevent moisture, moisture absorption, deformation or decay of the floor.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
