Cross latch floor
Technical field
The utility model relates to a kind of latch floor, particularly a kind of cross latch floor.
Background technology
At present, flat mouthful and snap close dual mode are mainly adopted in the connection of existing wood flooring on the market, are directly to be connected with tongue-and-groove with tenon between the wood flooring by wood flooring.Its weak point is, because wood flooring all is to be made by shaving board, HDF, MDF or timber etc., though its upper and lower surface has waterproof action after through processing, the floor is making moist, is soaking or when dry, quality problems such as projection or cracking will appear in the floor gap place.
Summary of the invention
The purpose of this utility model is to solve the connection of existing wood flooring in the market mainly to adopt flat mouthful and snap close dual mode, is directly to be connected with tongue-and-groove with tenon between the wood flooring by wood flooring.Its weak point is, because wood flooring all is to be made by shaving board, HDF, MDF or timber etc., though its upper and lower surface has waterproof action after through processing, the floor is making moist, is soaking or when dry, the problem of situations such as projection or cracking will appear in the floor gap place.The utility model designs cross latch floor, comprise floor, tongue-and-groove, it is characterized in that: be provided with cross connector between the floor, the joint tongue at connector two matches with the tongue-and-groove on adjacent floor, and the head of joint tongue is a circular arc, and the width of the head of joint tongue slightly is wider than root, the shape and the joint tongue of floor upper tenon groove are corresponding, the top of connector is provided with boss, matches with the side on adjacent floor in the lower end of boss, and the end face of boss can be plane or curved surface.The utility model has the advantages that anti-sealing infiltrates the seam crossing on floor and causes floor gap place projection, prevents also that simultaneously the edge on floor is worn; Adopted novel tenon tongue structure, the processing on floor is simple, easy for installation, has guaranteed the assembly unit quality on floor; Improved the utilization rate of timber resources; Can adopt different material, color to increase the decorative effect on floor according to demand; Avoided since the expansion on floor and contraction cause warping and ftracture.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Comprise floor 1, tongue-and-groove 2 among the figure, it is characterized in that: 1 on floor is provided with cross connector 3, the joint tongue 4 at connector 3 two matches with the tongue-and-groove 2 on adjacent floor 1, the head 5 of joint tongue 4 is a circular arc, the width of the head 5 of joint tongue slightly is wider than root 6, and the shape of floor 1 upper tenon groove 2 is corresponding with joint tongue 4, and the top of connector 3 is provided with boss 7, match with the side 9 on adjacent floor 1 in the lower end 8 of boss 7, the end face 10 of boss 7 can be plane or curved surface.By the connector 3 that is independent of floor 1 two adjacent floors 1 are linked together, joint tongue 4 by cross structure and the tongue-and-groove 2 on adjacent floor closely cooperate and stop adjacent two floors 1 to separate to both sides, make the limit portion on floor 1 be embedded in hermetically below the boss 7 of connector 3, has the snap close function simultaneously, adopt this syndeton to connect the floor, 1 both sides, floor only need mortice opening 2, make the processing on floor become simple and install very convenient, improved the assembly unit quality on floor, can prevent the seam crossing on sealing infiltration floor effectively and cause floor gap place projection, and the edge that prevents the floor is worn, also avoided simultaneously since the expansion on floor and contraction cause warping and ftractureing.
