Abstract

It is related to a kind of Double tongue-and-groove floor with novel, including cuboid plate body, two sides of cuboid plate body are equipped with the double groove being made of two grooves and two tenons, the section of two grooves and two tenons is in sector, and two scalloped recess are concentric, two fan-shaped tenons are concentric, when two grooves of one of Double tongue-and-groove floor coordinate with two tenons of another piece of Double tongue-and-groove floor, four sectors of two grooves and two tenons at cooperation are concentric, and fan-shaped central angle A meets 60 ° >=A >=10 °.The utility model also has enough spaces to complete installation in the last floorboard close to wall, connection mode cooperation is close, it does not need to use glue, floor plaster is complete to be can be used, and even if the connection mode floor is shunk, the tenon and groove of cooperation will not be detached from, therefore will not generate gap between floor in this direction.

Description

A kind of Double tongue-and-groove floor

Technical field

The utility model is related to a kind of Double tongue-and-groove floors.

Background technology

Existing Double tongue-and-groove floor be all using groove and tenon joggle, but groove and tenon be all linearly dock namely Can be completed docking toward direction force after groove and tenon alignment, this docking mode be installed to lean on wall last During block floor, often due to insufficient space, installation is inconvenient, and the connection mode floor easily shrinks and generates gap.

Utility model content

In view of the deficiencies of the prior art, the utility model is intended to provide a kind of Double tongue-and-groove floor, close to the last of wall Floorboard also has enough spaces to complete installation, and connection mode cooperation is close, does not need to use glue, floor plaster is complete Use, even and if the connection mode floor shrink, the tenon and groove of cooperation will not be detached from, thus in this direction floor it Between will not generate gap.

The utility model is achieved through the following technical solutions.

A kind of Double tongue-and-groove floor, including cuboid plate body, two sides of cuboid plate body are equipped with by two grooves and two The section of the double groove that a tenon is formed, two grooves and two tenons is in sector, and two scalloped recess are concentric, Two fan-shaped tenons are concentric, when two grooves of one of Double tongue-and-groove floor and two tenons of another piece of Double tongue-and-groove floor are matched During conjunction, four sectors of two grooves and two tenons at cooperation are concentric, and fan-shaped central angle A meets 60 ° >=A >=10 °.

Preferably, the fan-shaped center of circle is located on the face where the side of cuboid plate body.

Preferably, when floor is face-up, the fan-shaped central angle for the groove being located above is more than underlying recessed The fan-shaped central angle of slot, and difference B meets 40 ° >=B >=20 °, corresponds, the fan-shaped center of circle for the tenon being located above Angle is more than the fan-shaped central angle of underlying tenon, and difference C meets B=C.

Preferably, the slot bottom section of two grooves is arc-shaped, corresponds, and the head section of two tenons is arc-shaped.

Preferably, the tenon coordinates gapless with the groove.

Preferably, two end faces of cuboid plate body are equipped under the L-type of mutual snapping and are detained on button and inverted L shape.

Preferably, the head and slot bottom rounding angle detained under the L-type and detained on inverted L shape.

Preferably, button and snap fit on inverted L shape close gapless under the L-type.

Compared with prior art, the utility model has the advantages that：The utility model groove and tenon are sector, and when installation is convex Tenon alignment indentation, slowly rotate up to it is fully mated, it is fully mated due to needing to turn to, though close to wall last Block floor also has enough spaces to complete installation, and connection mode cooperation is close, does not need to using glue, floor plaster is complete to be made With, even and if the connection mode floor shrink, the tenon and groove of cooperation will not be detached from, therefore in this direction between floor Gap will not be generated；The utility model end face uses and is fastened on button and inverted L shape under L-type, does not influence floor and is rotatably assorted, simultaneously It is fastened on button and inverted L shape under L-type, floor is shunk will not generate gap in this direction.

Fig. 3 is that width direction schematic cross-section before camber is done on the tenon head of the utility model；

In figure：1st, cuboid plate body, 2, groove, 3, tenon, 4, detain under L-type, 5, detain on inverted L shape.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as the utility model It limits.

As shown in Figure 1 to Figure 3, a kind of Double tongue-and-groove floor, including cuboid plate body（1）, cuboid plate body（1）Two sides Face is equipped with by two grooves（2）With two tenons（3）The double groove of composition, two grooves（2）With two tenons（3） Section in sector, and two scalloped recess（2）With one heart, two fan-shaped tenons（3）With one heart, when one of Double tongue-and-groove floor Two grooves（2）With two tenons of another piece of Double tongue-and-groove floor（3）During cooperation, two grooves at cooperation（2）It is convex with two Tenon（3）Four sectors it is concentric, the fan-shaped center of circle is located at cuboid plate body（1）Side where face on, when floor front court When upper, the groove that is located above（2）Fan-shaped central angle be more than underlying groove（2）Fan-shaped central angle, it is and poor Value B meets 40 ° >=B >=20 °, and fan-shaped central angle A meets 60 ° >=A >=10 °, the groove that the present embodiment is located above（2）Fan The central angle of shape is 56 °, underlying groove（2）Fan-shaped central angle be 27 °, difference is 29 °, is corresponded, position Tenon in top（3）Fan-shaped central angle be more than underlying tenon（3）Fan-shaped central angle, and difference C meets B =C, two grooves（2）Slot bottom section it is arc-shaped, correspond, two tenons（3）Head section it is arc-shaped, it is described convex Tenon（3）With the groove（2）Coordinate gapless, cuboid plate body（1）Two end faces be equipped with mutual snapping L-type under detain（4） It is detained on inverted L shape（5）, detain under the L-type（4）It is detained on inverted L shape（5）Head and slot bottom rounding angle, detain under the L-type（4） It is detained on inverted L shape（5）Coordinate gapless.

The foregoing is merely the utility model preferred embodiment, not thereby limit the utility model embodiment and Protection domain to those skilled in the art, should can appreciate that all in the utility model specification and diagram Hold made equivalent replacement and obviously change obtained scheme, the protection model of the utility model should all be included in In enclosing.
