Words like "a" or "an" used in the description of the patent application and the claims of the present application do not indicate a quantitative limitation, but indicate that there is at least one.

The "inside, outside, inside, outside" mentioned in the description and claims of this application, unless otherwise specified, are "inside, inside" close to the center of the floorboard in the horizontal direction, and "inside, inside" away from the center of the floorboard in the horizontal direction outside, outside".

In the description of the specification and claims of the present application, the orientation or positional relationship indicated by the terms "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplify the description, rather than indicating or implying that the referred device or unit must have a specific direction, be constructed and operate in a specific orientation, and therefore, should not be construed as a limitation on the present application.

Now, embodiments of the present application will be described with reference to the accompanying drawings.

Example 1:

The same as the traditional floor system, the floor system of this embodiment also includes a number of floor boards that are horizontally paved on the ground, the outer contour of each floor board is roughly rectangular, and the sides of each floor board are provided with floor buckles. , and adjacent floor boards are connected to each other by means of floor buckles on the sides.

Figure 1 shows two adjacent floorboards in the floor system, namely a first floorboard a and a second floorboard b, the side of the first floorboard a is provided with a male buckle 1, and the second floorboard The side edge of b is provided with a female buckle 2 that is adapted to the male buckle 1. The male buckle 1 and the female buckle 2 are configured so that the first floorboard a moves vertically downward relative to the second floorboard b. For locking, the male snap 1 and the female snap 2 are also configured to be disengaged (unlocked) from each other by vertically moving the first floorboard a relative to the second floorboard b.

The key improvement of this embodiment is that the male buckle 1 includes a vertical tongue socket 101 recessed upward and a horizontal tongue socket 102 recessed horizontally inward, while the female buckle 2 includes a vertical tongue 201 protruding upward and a horizontal tongue socket 201 extending horizontally outward. The elastic transverse tongue 202 that emerges. The vertical tongue 201 is embedded in the vertical tongue insertion groove 101, so as to lock the first floorboard a and the second floorboard b in the horizontal direction. The elastic transverse tongue 202 is embedded in the transverse tongue insertion groove 102, so as to elastically lock the first floorboard a and the second floorboard b in the vertical direction.

The so-called "elastic transverse tongue" does not specifically mean that the transverse tongue itself has elastic deformation ability, but: the "elasticity" of the transverse tongue can come from the transverse tongue itself, or it can come from other parts connecting the transverse tongue and the female buckle body. structure (such as the following spring arm in this embodiment). In this way, when the transverse tongue is subjected to a force in a specific direction (vertical direction), "displacement deformation" will occur, and the "displacement deformation" will recover after the aforementioned force is eliminated. The aforementioned "displacement deformation" may be the overall displacement of the transverse tongue, or the deformation and local displacement of the transverse tongue itself. Specifically in this embodiment, the following structure is adopted:

The female buckle 2 also includes a downwardly protruding elastic arm 203 and a deformation slit 204 located inside the elastic arm. The elastic transverse tongue 202 is integrally formed at the lower end of the elastic arm 203 .

In this embodiment, the elastic transverse tongue 202 and the vertical tongue 201 are separated by a certain distance in the horizontal direction, and the elastic transverse tongue 202 is located inside the vertical tongue 201 . Correspondingly, the horizontal tongue insertion groove 102 and the vertical tongue insertion groove 101 are separated by a certain distance in the horizontal direction, and the transverse tongue insertion groove 102 is located outside the vertical tongue insertion groove 101 . In some other embodiments of the present application, the elastic transverse tongue 202 can also be provided on the outer side of the vertical tongue 201 , and the transverse tongue socket groove 102 can be provided on the inner side of the vertical tongue socket groove 101 correspondingly. The horizontal tongue inserting groove 102, the vertical tongue inserting groove 101 and the elastic horizontal tongue 202 and the vertical tongue 201 are arranged in a horizontal direction (specifically, the horizontal direction perpendicular to the connecting edge of the two floor plates), which facilitates the production of male and female buckles and vertical assembly, and at the same time, a sealing strip can be easily sandwiched between the male and female buckles for waterproofing, see the third embodiment for details.

1 to 6 , during assembly, the outer side of the upper half of the male buckle 1 on the first floorboard a moves vertically downward against the outer side of the upper half of the female buckle 2 on the second floorboard b. The elastic transverse tongue 202 on the female buckle 2 moves inward under the extrusion of the outer surface of the upper half of the male buckle 1, the elastic arm 203 is indirectly pressed (the elastic transverse tongue 202 is directly pressed), and the lower end deforms inward. When the transverse tongue inserting groove 102 moves down to the position of the elastic transverse tongue 202, the elastic transverse tongue 202 is not under pressure, the elastic arm 203 recovers its deformation, and the elastic transverse tongue 202 moves outward to be embedded in the transverse tongue inserting groove 102 to realize the male snap 1 Elastic locking with the female snap 2 in the vertical direction. At this time, the vertical tongue 101 of the female buckle 2 is just inserted into the vertical tongue insertion groove 101 of the male buckle 1 to realize the rigid locking of the male buckle 1 and the female buckle 2 in the horizontal direction.

When the first floorboard a and the second floorboard b need to be separated, a certain upward moving force can be applied to the first floorboard a by means of the negative pressure suction cup adsorbed on the upper surface of the first floorboard a, and the elastic transverse tongue 202 is directly affected by the negative pressure suction cup. When pressed, the elastic arm 203 is indirectly pressed, the upper end deforms inwardly, and the elastic transverse tongue 202 moves inwardly and disengages from the transverse tongue insertion groove 102 .

6, in order to facilitate the vertical locking and vertical separation of the male buckle 1 and the female buckle 2 (that is, the vertical locking and vertical separation of the first floorboard a and the second floorboard b) , in this embodiment, the lower half 202a of the outer side of the elastic transverse tongue 202 is set as a guiding slope with a high outer and inner low, and the upper half 202b of the outer side of the elastic transverse tongue 202 is set as a guiding slope with an outer low and an inner high. In the process of assembling and vertically separating the two floorboards, under the action of the aforementioned guiding slope, the vertical pressing force received by the elastic transverse tongue 202 is converted into a horizontal pressing force (horizontal component force), so that the elastic arm 203 can be more easily deformed.

Further, the upper half part 202a and the lower half part 202b of the outer surface of the elastic transverse tongue 202 are arc surfaces with a certain degree of smoothness. Furthermore, the aforementioned two arc surfaces are co-circular, so that the outer side surface of the elastic transverse tongue 202 is an arc surface as a whole.

In order to better guide the elastic transverse tongue 202 to be embedded in the transverse tongue insertion groove 102 and guide the elastic transverse tongue 202 to escape from the transverse tongue insertion groove 102 (when the first floorboard is subjected to a sufficiently large upward pulling force), the male buckle is used in this embodiment. 1. The lower side groove wall surface 102a of the upper transverse tongue socket groove 102 is set as a guide slope with an outer low and inner height, and the outer surface 103 of the male buckle 1 located directly below the transverse tongue socket groove 102 is set as a guide with a high outer and inner low. bevel. Further, the lower side groove wall surface of the aforementioned transverse tongue embedding groove 102 and the outer surface 103 of the male buckle located directly below the transverse tongue embedding groove are all arc surfaces.

In this embodiment, each floor buckle is an integral molded part, and is made of aluminum alloy profiles. Floor buckles can also be made of other materials, such as one-piece plastic parts.

Of course, we can also set the above-mentioned male buckle 1 or female buckle 2 as a split structure assembled by a plurality of components.

Each floorboard in this embodiment (including the above-mentioned first and second floorboards) is not a traditional wooden floorboard or a marble or ceramic tile floorboard, but a composite structure, which is mainly composed of a honeycomb aluminum plate 3 on the lower layer and a honeycomb aluminum plate on the upper layer. The wooden panels 4 are bonded and fixed to each other, and the floor buckles are bonded and fixed on the side of the honeycomb aluminum panel 3 .

The aforementioned wooden panels 4 can also be replaced by marble slabs, tile slabs or plastic slabs. The honeycomb aluminum plate 3 is composed of an upper layer aluminum plate 301, a lower layer aluminum plate 302 arranged in parallel below the upper layer aluminum plate, and an aluminum honeycomb core layer 303 fixedly connected between the upper layer aluminum plate and the lower layer aluminum plate. The area of the aluminum honeycomb core layer 303 is smaller than the area of the upper layer aluminum plate 301 and the lower layer aluminum plate 302, and each side edge of the aluminum honeycomb core layer 303 is located inside the corresponding sides of the upper layer aluminum plate 301 and the lower layer aluminum plate 302, so that the upper layer aluminum plate 301 A floor buckle embedding gap 3 a around the aluminum honeycomb core layer 303 is formed with the lower aluminum plate 302 . The above-mentioned floor buckles are inserted into the above-mentioned floor buckle insertion gaps 3a. Moreover, the floor buckle part embedded in the aforementioned floor buckle embedding gap 3a is bonded and fixed with the upper layer aluminum plate 301 and the lower layer aluminum plate 302 .

Referring to Figure 10 again, in fact, the side of the first floorboard a is not only provided with the male buckle 1 of the above structure, but also provided with the female buckle 2 of the above structure, and the male buckle on the first floorboard a is provided. and the female snaps are respectively arranged on different sides of the first floorboard. Similarly, the side of the second floor board b is not only provided with the female buckle 2 of the above structure, but also provided with the male buckle 1 of the above structure. The male buckle and the female buckle on the second floor board b are respectively arranged on Different sides of the second floorboard. In this way, the third floorboard c can be continuously connected to the other side of the first floorboard a, and the fourth floorboard d can be connected to the other side of the second floorboard b, as shown in FIG. 11 .

It should be noted that the "upper end, lower end and middle part" of the elastic arm mentioned in the claims and description of the present application should not be interpreted in a narrow sense, and the "upper end" should not be interpreted as the upper end position of the elastic arm, "Lower end" should not be limitedly interpreted as the lower end position of the spring arm, and "middle" should not be limitedly interpreted as the geometric midpoint of the length dimension of the spring arm. Generally speaking, if the length of the elastic arm is divided into three sections, then the upper end of the upper section can be called the upper end of the elastic arm, the lower section can be called the lower end of the elastic arm, and the middle section can be called the elastic arm. the middle of.

Embodiment 4:

Fig. 13 shows the fourth specific embodiment of the floor system of the present application. The floor system has basically the same structural form as the first embodiment, the only difference is:

The above-mentioned sealing strip 5 is specifically arranged at a position between the elastic transverse tongue 202 and the vertical tongue 201 , and is vertically clamped by the male buckle 1 and the female buckle 2 . This prevents water above the floor system from penetrating down the floor system through the gap where the floorboard joins fit.

Embodiment 5:

Figures 14 to 16 show the fifth specific embodiment of the floor system of the present application. The floor system is similar in structure to the first embodiment, and the only difference is:

In this implementation, the body part of each floor board is all made of wood—commonly known as wood floor or wood floor board, including solid wood floor, laminate floor, solid wood composite floor, multi-layer composite floor, bamboo floor and cork floor, etc., no longer It is a composite structure of honeycomb substrate and wood panel. The body part of the female buckle 2 is a wooden material integrated with the floorboard body—while making the wooden floorboard body part, the female buckle body is directly and integrally processed at the side of the floorboard body. Afterwards, the elastic arm 203 with the elastic transverse tongue 202 is fixedly connected to the wooden female buckle body. The aforementioned elastic arm with the elastic transverse tongue is preferably made of metal or plastic with certain deformability and high structural strength. The male buckle 1 is completely made with the body part of the floorboard, that is, the male buckle 1 is a wooden structure as a whole, and is integrated with the body structure of the floorboard. The male buckle 1 is directly and integrally processed at the side of the main body.

In this way, when the male buckle 1 continues to move downward to cause the elastic arm and the elastic transverse tongue to deform inwardly, the horizontal thrust exerted by the male buckle 1 is resisted by the vertical tongue 201, and there is no need for the installation worker to apply a direction to the first floorboard a. The horizontal thrust of the second floor plate further reduces the installation difficulty of the two floor plates.

That is to say, when the elastic arm and the elastic transverse tongue are about to be pressed and deformed, the vertical tongue 201 cooperates with the vertical tongue insertion groove 101 to form a vertical guide.
