Abstract

The utility model relates to a structure for putting together having three tongues and multiple locking used for reinforce wood floors. A groove and tongue is composed of an upper facade (10), a first keyway (6) inward concave, a second keyway (12) downward concave, and a third joint tongue (4) upward convex, which are connected. A cog is composed of the connection of an upper facade (10), a first joint tongue (1) outward convex, a second joint tongue (3) downward convex, and a third keyway (14) with an inward recessing upper part, which are matched with the grooved and tongue. The lower face (11) of first keyway (6) and the lower groove face (13) of the second keyway (12) are in parallel with the ground. The upper faces of the first keyway (6) and the first joint tongue (1) are provided with matched an oblique plane (15). The structure for putting together is provided with a plurality of locking points and is tightly put together, effectively overcoming the creep of assembling gaps and keyways.

Description

Three many snap closes of tongue splicing constructions

Affiliated technical field

The utility model relates to a kind of snap close splicing construction that is used for the laminated flooring splicing.

Background technology

At present, known laminated flooring splicing construction: the one, flat mouthful tongue and groove inserts joint tongue in the tongue-and-groove, promptly finishes the splicing of laminated flooring; But the laminated flooring of this structure is when installing splicing, and it is bigger influenced by human factor; If install improper or the lath distortion, quality problems such as gap can occur splicing.The 2nd, the common lock button, its coupling mechanism force is less, and relies on the elastic deformation of tongue-and-groove when splicing, makes joint tongue enter tongue-and-groove, because the internal bond strength of medium density fibreboard is limited, can not have the deformation behavior of metal material; Therefore, so just might cause the tongue-and-groove plastic strain, can't recover behind the spreading.

Summary of the invention

In order to overcome the defective that existing these two kinds of splicing constructions exist at laminated flooring itself and to improve installation work, the utility model provides a kind of three many snap closes of tongue splicing constructions, this many snap closes of three tongues splicing construction can not only make laminated flooring be stitched together effectively, and the piece when utilizing mechanical force to proofread and correct splicing, splicing has closely overcome the plastic strain when splicing of assembly unit gap and tongue-and-groove effectively.

The snap close splicing construction that the utility model adopted is that the tenon by the tongue and groove of plate sidepiece and relative plate constitutes, and tongue and groove is by last facade, first tongue-and-groove that concaves, be formed by connecting to second recessed tongue-and-groove and the 3rd joint tongue that raises up; Tenon by the last facade that matches with tongue and groove, to first joint tongue of outer lug, to second joint tongue of lower convexity and top inwardly the 3rd recessed tongue-and-groove be formed by connecting, form the many buckle structures of three tongues; The following groove face of the soffit of first tongue-and-groove and second tongue-and-groove is parallel to the ground, and the upper surface of the upper surface of first tongue-and-groove and first joint tongue has the inclined-plane that matches.

Described second tongue-and-groove is the trapezoidal of the length of side on, following weak point, and both sides have the inclined-plane, and the 3rd tongue-and-groove has the inclined-plane that matches with this inclined-plane.

Has the gap after the described two plates splicing.

The beneficial effects of the utility model are, can be when laminated flooring be stitched together effectively, and the piece when utilizing mechanical force to proofread and correct splicing, splicing is closely.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model sectional drawing.

Fig. 2 is the splicing schematic diagram of three many snap closes of tongue splicing constructions.

Fig. 3 is the splicing effect schematic diagram of three many snap closes of tongue splicing constructions.

1 first joint tongue among the figure, 2 inclined-planes, 3 second joint tongues, 4 the 3rd joint tongues, 5 inclined-planes, 6 first tongue-and-grooves, 7,16,17,18 gaps, 8 tops, 9 bottoms, 10, the last facade of 10`, 11 soffits, 12 second tongue-and-grooves, 13 times groove faces, 14 the 3rd tongue-and-grooves, 15 cooperate the inclined-plane, and A lath, B lath, N be firmly signal downwards.

The specific embodiment

Fig. 1 shows the tongue and groove part on A plate right side, and this tongue and groove top (8) is short, and following (9) are long, by last facade (10), first tongue-and-groove (6) that concaves, be formed by connecting to recessed second tongue-and-groove (12) and the 3rd joint tongue (4) that raises up.Wherein second tongue-and-groove (12) is the trapezoidal of the length of side on, following weak point, and both sides have inclined-plane (5), and the soffit (11) of first tongue-and-groove (6) and the following groove face (13) of second tongue-and-groove (12) are parallel to the ground.Fig. 1 also shows the tenon part of the B plate that matches with A plate tongue and groove, this tenon by last facade (10`), to first joint tongue (1) of outer lug, to second joint tongue (3) of lower convexity and top inwardly recessed the 3rd tongue-and-groove (14) be formed by connecting, the 3rd tongue-and-groove (14) has the inclined-plane (2) that matches with inclined-plane (5).

In Fig. 1, first joint tongue (1) inserts in first tongue-and-groove (6), and they have the cooperation inclined-plane (15) of equal angular, and the angle on this inclined-plane is just within the locking angle, therefore its function is not only to guarantee that the spliced height unanimity of two plates is errorless, and also has locking function;

In Fig. 2, when splicing A, B two plates, the B plate is with 45.The angle oblique cutting is gone in the A board slot, at this moment apply power N gently and press down the B plate, the inclined-plane of B plate (2) contacts gradually with A plate inclined-plane (5), and the B plate is produced a pulling force forward, reach the effect of locking retaining at last, the A plate can keep forever to the coupling mechanism force of B plate, and this splicing construction has permanent ageing.

Fig. 3 shows two plates, and (A, B) spliced gap (16,17,18), gap (7) are in order to guarantee the full contact in cooperation inclined-plane (15) between first joint tongue (1) and first tongue-and-groove (6), locate reliably that self-locking is simple and direct.
