Description

Technical Field

[0001] This application relates to the field of floors, and particularly to a floor system and a floor buckle. Background Art

[0002] The Chinese invention patent with the patent number CN200880124150.6 discloses a floor buckle structure, especially at the side position of the floor. The corresponding text part of the specification of this patent document and the attached Figure 2 a and attached Figure 2 b disclose that this male buckle and female buckle are locked and matched with each other in a relative rotation manner and disengaged from each other in a reverse rotation manner. However, the male buckle and female buckle of this structure have the following defects:

[0003] 1. After assembly, the male buckle and female buckle have four pairs of closely contacting mating surfaces (see the 31-32 mating surface, 33-34 mating surface, 35-36 mating surface, and 11-12 mating surface in the attached Figure 2 b of this patent document) to ensure that the male buckle and female buckle and two adjacent floorboards are locked simultaneously in the horizontal and vertical directions. Otherwise, there will be horizontal or vertical movement space between two adjacent floorboards, reducing the user experience. This requires that after the male and female buckles are assembled, the tongue and groove part of the floor buckle, especially the female buckle, is always in a deformed state of expanding outward in multiple directions, and the male buckle is always in a deformed state of contracting inward in multiple directions. This requires that the floorboards, especially the male and female buckles on the floorboards, must have the deformation ability (toughness) in multiple directions. Therefore, the floor buckle in the above patent document is currently only applicable to traditional wooden floors, and its male and female buckles can only be made of a wooden structure with a certain toughness.

[0004] 2. Referring to the attached Figure 2 a and attached Figure 2 b of the above patent document, after assembly, the mating surfaces that limit the upward displacement of the male buckle relative to the female buckle are set and only set at the head of the tongue 10 and the upper side wall of the tongue groove 9 - mating surfaces 33 and 34. When the right floorboard 1 ， is subjected to an upward external force or the left floorboard 1 ，， is subjected to a downward external force, the head of the tongue 10 (compared with the root or other parts) is very easy to produce a downward bending deformation, and the thickness of the female buckle part above the tongue groove 9 is relatively thin, and it is also easy to receive an upward bending deformation, resulting in a relative movement in the vertical direction between the left and right floorboards and reducing the user experience.

[0005] 3. The limit structures of the male and female buckles of this structure in the horizontal and vertical directions are all concentrated in the upper half of the floor buckle, and the structural strength of the lower half of the male and female buckles is not effectively utilized, increasing the stress burden and design difficulty of the upper half of the floor buckle. Summary of the Invention

[0006] The technical problem to be solved by this application is to provide a floor system and a floor buckle to more conveniently manufacture and assemble floor buckles for floor plates, especially floorboards.

[0007] The technical solution of this application is as follows:

[0008] A floor system includes a first floor plate horizontally arranged with male buckles on its side and a second floor plate horizontally arranged with female buckles on its side. The male buckle includes a tongue protruding horizontally outward, and the female buckle includes a tongue groove recessed horizontally inward. The male buckle and the female buckle are configured to be locked with each other by the forward rotation of the first floor plate relative to the second floor plate and disengaged from each other by the reverse rotation of the first floor plate relative to the second floor plate. Moreover, the male buckle and the female buckle cooperate with each other and lock the first floor plate and the second floor plate simultaneously in the vertical direction and the horizontal direction.

[0009] The tongue includes a vertical protrusion formed on the upper surface of the tongue and protruding upward. The tongue groove includes a vertical sub-groove formed on the upper side wall of the tongue groove and recessed upward. The male buckle includes a first inclined surface located below the tongue and having a lower outer side and a higher inner side. The female buckle includes a second inclined surface located below the tongue groove and having a higher outer side and a lower inner side.

[0010] The tongue extends into the tongue groove, and the vertical protrusion extends into the vertical sub-groove. The inner surface of the vertical protrusion is arranged in contact with the outer side wall surface of the vertical sub-groove to limit the first floor plate and the second floor plate from moving away from each other in the horizontal direction.

[0011] The first inclined surface and the second inclined surface are arranged in contact with each other to limit the first floor plate and the second floor plate from approaching each other in the horizontal direction and limit the upward vertical movement of the first floor plate relative to the second floor plate.

[0012] On the basis of the above technical solution, this floor system of this application further includes the following preferred solutions:

[0013] The tongue further includes a first horizontal surface formed on the lower surface of the tongue, and the tongue groove further includes a second horizontal surface formed on the lower side wall of the tongue groove. The first horizontal surface and the second horizontal surface are arranged in contact with each other to limit the downward vertical movement of the first floor plate relative to the second floor plate.

[0014] The force exerted by the second inclined surface on the first inclined surface causes the male buckle to have a tendency to move downward vertically relative to the female buckle, thereby causing the first horizontal surface and the second horizontal surface to be arranged in contact with each other.

[0015] All surfaces of the tongue except the first horizontal surface and the inner surface of the vertical protrusion are arranged with a clearance from the groove wall surface of the tongue groove.

[0016] The first horizontal surface is provided at the root of the tongue, and the second horizontal surface is provided at the notch of the tongue groove.

[0017] Both the first inclined surface and the second inclined surface are flat surfaces, and the angles between the first inclined surface and the second inclined surface and the horizontal plane are 30 - 85 degrees.

[0018] All surfaces of the male snap below the tongue except the first inclined surface are arranged with a clearance from the surface of the female snap.

[0019] The first inclined surface extends to the bottom of the male snap, and the second inclined surface extends to the bottom of the female snap.

[0020] The vertical protrusion is provided at the outer end of the tongue, and the inner groove wall of the vertical sub - groove is formed on the bottom wall of the tongue groove.

[0021] The male snap and the female snap are respectively integrally formed parts made of plastic or metal.

[0022] The male snap is a wooden structure integrally connected to the first floor board, and the female snap is a wooden structure integrally connected to the second floor board.

[0023] The male snap includes a sealing strip embedding groove that is horizontally recessed inwardly above the tongue. The lower groove wall of the sealing strip embedding groove is formed on the tongue, and a sealing strip horizontally clamped between the male snap and the female snap is embedded in the sealing strip embedding groove.

[0024] A floor buckle includes a male snap and a female snap. The male snap includes a tongue that protrudes horizontally outward, and the female snap includes a tongue groove that is horizontally recessed inwardly. The male snap and the female snap are configured to: be locked to each other by the forward rotation of the male snap relative to the female snap, be disengaged from each other by the reverse rotation of the male snap relative to the female snap, and the male snap and the female snap cooperate with each other and are locked simultaneously in the vertical direction and the horizontal direction;

[0025] The tongue includes a vertical protrusion formed on the upper surface of the tongue and protruding upward. The tongue groove includes a vertical sub - groove formed on the upper groove wall of the tongue groove and recessed upward. The male snap includes a first inclined surface that is lower outside and higher inside below the tongue, and the female snap includes a second inclined surface that is higher outside and lower inside below the tongue groove;

[0026] The tongue projects into the tongue groove, and the vertical protrusion projects into the vertical sub-groove. The inner surface of the vertical protrusion is arranged in abutment against the outer groove wall surface of the vertical sub-groove to limit the male buckle and the female buckle from moving away from each other in the horizontal direction;

[0027] The first inclined surface is arranged in abutment against the second inclined surface to limit the male buckle and the female buckle from approaching each other in the horizontal direction and to limit the male buckle from moving upward vertically relative to the female buckle.

[0028] On the basis of the above technical solution, this floor buckle of the present application further includes the following preferred solutions:

[0029] The tongue further includes a first horizontal surface formed on the lower surface of the tongue, and the tongue groove further includes a second horizontal surface formed on the lower groove wall of the tongue groove. The first horizontal surface is arranged in abutment against the second horizontal surface to limit the male buckle from moving downward vertically relative to the female buckle.

[0030] The force exerted by the second inclined surface on the first inclined surface causes the male buckle to have a tendency to move downward vertically relative to the female buckle, thereby causing the first horizontal surface to be arranged in abutment against the second horizontal surface.

[0031] The present application can achieve the following beneficial effects:

[0032] 1. Only under the abutting and cooperating actions of the two pairs of mating surfaces, namely, the inner surface of the vertical protrusion and the outer groove wall surface of the vertical sub-groove, and the first inclined surface and the second inclined surface, the mutual separation and mutual approach of the two floorboards in the horizontal direction are restricted. At the same time, the upward movement of the first floorboard in the vertical direction is also restricted. The locking of the two floorboards in three directions can be achieved only by means of two pairs of mating surfaces, which is ingenious and easy to assemble. Moreover, it is easy to implement this mating structure: it is only necessary that the inner wall of the vertical protrusion, or the outer groove wall of the vertical sub-groove, or the first inclined surface part of the male buckle, or the second inclined surface of the female buckle has a certain flexibility.

[0033] 2. The first horizontal surface of the tongue is arranged in abutment with the second horizontal surface of the tongue groove, thereby restricting the vertical downward movement of the first floorboard relative to the second floorboard. After the assembly is completed, the force exerted by the second inclined surface on the first inclined surface causes the male buckle to have a tendency to move vertically downward relative to the female buckle. This tendency will naturally cause the first horizontal surface and the second horizontal surface to always press against each other, without the need for particularly complex designs for the structures and positions of the first horizontal surface and the second horizontal surface. In terms of the design difficulty of the floor buckle, it is obviously much easier to achieve the mutual locking of two floorboards in the vertical and horizontal directions through only three pairs of mating surfaces than to achieve the mutual locking of two floorboards in the vertical and horizontal directions through four pairs of mating surfaces in the background patent. Moreover, the mutual abutment of one pair of mating surfaces is naturally achieved by the relative abutment of the other two pairs of mating surfaces.

[0034] 3. The first horizontal surface is provided at the root of the tongue, and the second horizontal surface is provided at the notch of the tongue groove. In practical applications, the first horizontal surface mainly bears the upward pressure from the female buckle, and the second horizontal surface mainly bears the downward pressure from the male buckle. By providing the first horizontal surface at the root of the tongue, even if the first horizontal surface receives a large upward pressure, the tongue will not undergo obvious deformation or breakage. Although the second horizontal surface is provided at the notch of the tongue groove, the female buckle part below the tongue groove has a relatively large thickness and can fully withstand a large downward pressure without obvious deformation or breakage.

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0050] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present application belongs. The words such as "a" or "one" used in the description of the patent application specification and claims of the present application do not denote a limitation in quantity, but rather denote the existence of at least one.

[0051] As used in the description and claims of this application, the terms "inner", "outer", "inner side", and "outer side", unless otherwise specified, refer to "inner" and "inner side" when approaching the center of the floorboard in the horizontal direction, and "outer" and "outer side" when away from the center of the floorboard in the horizontal direction.

[0052] In the description of this application's specification and claims, the orientation or positional relationship indicated by terms such as "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to this application.

[0053] Now, embodiments of this application will be described with reference to the accompanying drawings. Embodiment 1:

[0054] Similar to the traditional floor system, the floor system of this embodiment also includes many floorboards horizontally laid on the ground. The outer contour of each floorboard is generally rectangular, and floor locks are provided on the side edges of each floorboard. Adjacent floorboards are connected to each other by the floor locks on the side edges.

[0055] Figure 4 Two adjacent floorboards in the floor system are shown, which are Figure 4 the first floorboard a and the second floorboard b horizontally arranged in Figure 6 and Figure 7 shown. Similar to the prior art cited in the background art part of this application: a male lock 1 is provided on the side edge of the first floorboard a, and a female lock 2 adapted to the male lock 1 is provided on the side edge of the second floorboard b. The male lock 1 includes a tongue 101 extending horizontally outwards, and the female lock 2 includes a tongue groove 201 that is horizontally recessed inwards and adapted to the aforementioned tongue 101. As

[0056] The key improvement of this embodiment lies in that the above-mentioned male lock 1 and female lock 2 adopt a brand-new cooperation structure, specifically as follows:

[0057] The tongue 101 that is part of the male snap fastener includes a vertical protrusion 1012 formed on the upper surface of the tongue and protruding upward: The tongue 101 obviously has its own surface structure, and the tongue 101 extends horizontally outward from the male snap fastener body structure, so the surface 1011 of the tongue 101 obviously includes an upper surface and a lower surface. In this embodiment, an upwardly convex vertical protrusion 1012 is integrally provided on its upper surface.

[0058] The tongue groove 201 that is part of the female snap fastener includes a vertical sub-groove 2012 formed on the upper side wall of the tongue groove and recessed upward: The tongue groove 201 obviously has a side wall structure, and the tongue groove 201 extends horizontally inward from the female snap fastener body structure (surface), so the side wall 2011 of the tongue groove 201 obviously includes an upper side wall and a lower side wall. In this embodiment, an upwardly recessed vertical sub-groove 2012 is integrally provided at its upper side wall.

[0059] In addition to the tongue 101 having the above structure, the male snap fastener 1 further includes a first inclined surface 1021 that is lower on the outside and higher on the inside and is located below the tongue 101: The male snap fastener 1 obviously also has its own surface structure. The aforementioned first inclined surface 1021 is part of the surface of the male snap fastener 1, and this first inclined surface 1021 is located below the above-mentioned first horizontal surface 1011a, and the inclination direction of this first inclined surface 1021 is lower on the outside and higher on the inside. The specific meanings of "inside" and "outside" have been explained above. The so-called "lower on the outside and higher on the inside" means that the height of the side of the first inclined surface 1021 that is far from the central part of the first floor board (which can be called the outer side of the first inclined surface 1021) is lower than the height of the side of the first inclined surface 1021 that is close to the central part of the first floor board (which can be called the inner side of the first inclined surface 1021).

[0060] Correspondingly, in addition to the tongue groove 201 having the above structure, the female snap fastener 2 further includes a second inclined surface 2021 that is higher on the outside and lower on the inside and is located below the tongue groove 201: The female snap fastener 2 obviously also has its own surface structure. The aforementioned second inclined surface 2021 is part of the surface of the female snap fastener, and the inclination direction of this second inclined surface 2021 is higher on the outside and lower on the inside. The so-called "higher on the outside and lower on the inside" means that the height of the side of the second inclined surface 2021 that is far from the central part of the second floor board (which can be called the outer side of the second inclined surface 2021) is higher than the height of the side of the second inclined surface 2021 that is close to the central part of the second floor board (which can be called the inner side of the first inclined surface 1021).

[0061] The upwardly protruding vertical protrusion 1012 obviously has an inner surface close to the central part of the first floor board and an outer surface far from the central part of the first floor board. The upwardly recessed vertical sub-groove 2012 obviously has an inner surface close to the central part of the second floor board and an outer surface close to the central part of the second floor board.

[0062] In Figure 4 After the male snap 1 of the first floor board a and the female snap 2 of the second floor board b are locked with each other, the tongue 101 of the male snap 1 extends into the tongue groove 201 of the female snap 2, and the vertical protrusion 1012 on the tongue 101 extends into the vertical sub-groove 2012 in the tongue groove 201. The inner surface 1012a of the vertical protrusion 1012 is arranged in abutment with the outer groove wall surface 2012a of the vertical sub-groove 2012, thereby restricting the first floor board a and the second floor board b from moving away from each other in the horizontal direction: the first floor board a cannot move away from the second floor board b in the horizontal direction. The first inclined surface 1021 and the second inclined surface 2021 are arranged in abutment with each other, thereby restricting both the first floor board a and the second floor board b from approaching each other in the horizontal direction and restricting the first floor board a from moving upward vertically relative to the second floor board b: the first floor board a can neither move closer to the second floor board b in the horizontal direction nor move upward vertically relative to the second floor board b.

[0063] To ensure that after the male and female snaps are locked with each other, the inner surface 1012a of the vertical protrusion 1012 is arranged in abutment with the outer groove wall surface 2012a of the vertical sub-groove 2012, and at the same time the first inclined surface 1021 and the second inclined surface 2021 are arranged in abutment with each other, it is very easy to achieve: as long as the inner side wall of the vertical protrusion 1012, or the outer groove wall of the vertical sub-groove 2012, or the first inclined surface 1021 part of the male snap 1, or the second inclined surface 2021 of the female snap has a certain flexibility (or deformation ability), after the assembly is completed, the tongue is Figure 4 subjected to a pair of tensile forces in the left-right direction in

[0064] It can be seen that only under the abutting and cooperating action of these two pairs of mating surfaces, namely, the inner surface 1012a of the vertical protrusion 1012 and the outer groove wall surface 2012a of the vertical sub-groove 2012, and the first inclined surface 1021 and the second inclined surface 2021, the mutual separation and mutual approach of the two floor boards in the horizontal direction (specifically, the horizontal direction perpendicular to the docking edge of the two floor boards) are restricted, and at the same time, the upward movement of the first floor board in the vertical direction is also restricted. The locking of the two floor boards in three directions can be achieved only by means of two pairs of mating surfaces, which is very ingenious.

[0065] As can be seen from the above, in this embodiment, by ingeniously designing the structures of the male and female snaps, after the adjacent floor boards are locked and connected, they can neither move away from each other nor approach each other in the horizontal direction, and the first floor board cannot move upward relative to the second floor board in the vertical direction. However, the downward movement of the first floor board is not restricted. Based on this, the structures of the male snap 1 and the female snap 2 in this embodiment are further optimized:

[0066] The tongue 101, which is part of the male fastener 1, further includes a first horizontal surface 1011a formed on the lower surface of the tongue. The first horizontal surface 1011a is part of the lower surface of the tongue. The tongue groove 201 of the tongue groove 201 further includes a second horizontal surface 2011a formed on the lower groove wall of the tongue groove. The second horizontal surface 2011a is part of the lower groove wall surface of the tongue groove. After assembly, the aforementioned first horizontal surface 1011a and the second horizontal surface 2011a are arranged in abutment, thereby further restricting the vertical downward movement of the first floor board a relative to the second floor board b.

[0067] Through simple force analysis, it can be known that the first inclined surface 1021 on the male fastener 1 and the second inclined surface 2021 on the female fastener 2 are arranged obliquely in a specific direction. After assembly, the mutually abutting first inclined surface 1021 and second inclined surface 2021 produce this effect: the force (downwardly inclined) exerted by the second inclined surface 2021 on the first inclined surface 1021 causes the male fastener 1 to have a tendency to move vertically downward relative to the female fastener 2. This tendency further causes the first horizontal surface 1011a and the second horizontal surface 2021 to be pressed against each other. Assume that after the connection of the male and female fasteners is just completed, there is a certain vertical gap between the first horizontal surface 1011a and the second horizontal surface 2021. At this time, since the first inclined surface 1021 and the second inclined surface 2021 are tightly pressed against each other, the force exerted by the second inclined surface 2021 on the first inclined surface 1021 will cause the male fastener 1 to move downward, thereby causing the first horizontal surface 1011a and the second horizontal surface 2021 to approach each other and abut against each other.

[0068] It can be seen that under the abutting and mating action of the three pairs of mating surfaces, namely, the inner surface 1012a of the vertical protrusion 1012 and the outer groove wall surface 2012a of the vertical sub-groove 2012, the first inclined surface 1021 and the second inclined surface 2021, and the first horizontal surface 1011a and the second horizontal surface 2021, the mutual separation and mutual approach of the two floor boards in the horizontal and vertical directions are restricted at the same time. In terms of the design difficulty of the floor fastener, it is obviously much easier to achieve the mutual locking of the two floor boards in the vertical and horizontal directions through only three pairs of mating surfaces than to achieve the mutual locking of the two floor boards in the vertical and horizontal directions through four pairs of mating surfaces in the background patent. Moreover, the mutual abutment of one pair of mating surfaces is naturally achieved by the relative abutment action of the other two pairs of mating surfaces.

[0069] It should be noted that the "abutting arrangement" mentioned in the description and claims of this application can be partial abutment or full-area abutment. Obviously, as long as there are abutting contact parts between the inner surface 1012a of the vertical protrusion 1012 and the outer groove wall surface 2012a of the vertical sub-groove 2012, between the first horizontal surface 1011a and the second horizontal surface 2011a, and between the first inclined surface 1021 and the second inclined surface 2021, the two floor boards can be locked in the horizontal and vertical directions. Compared with "full-area abutment", "partial abutment" has lower requirements for the manufacturing precision of male and female fasteners. The "horizontal" mentioned in the description and claims of this application should not be narrowly understood as being completely parallel to the horizontal plane, but should be understood as "substantially horizontal" with an included angle within 30° with the horizontal plane; the "vertical" mentioned in the description and claims of this application should not be narrowly understood as being completely perpendicular to the horizontal plane, but should be understood as "substantially vertical" with an included angle within 30° with the vertical plane.

[0070] As previously mentioned, the first horizontal surface 1011a is a part of the surface 1011 of the tongue 101. And the vertical protrusion 1012 is a part of the tongue 101, so the inner surface 1012a of the vertical protrusion 1012 is naturally also a part of the surface 1011 of the tongue 101. It was also previously mentioned that the first horizontal surface 1011a, which is a part of the tongue surface, and the inner surface 1012a of the vertical protrusion 1012, which is a part of the tongue surface, are arranged in abutment with the groove wall 2011 of the tongue groove 201 (specifically, the second horizontal surface 2011a and the outer groove wall surface 2012a of the vertical sub-groove 2012) to lock the connection of the two floor boards. In this embodiment, the surface structures of other parts of the tongue 101 are not arranged in abutment with the groove wall 2011 of the tongue groove 201: the surfaces of the tongue except for the above-mentioned first horizontal surface 1011a and the inner surface 1012a of the vertical protrusion 1012 are arranged with a gap D from the groove wall 2011 of the tongue groove 201. In other words: except for the first horizontal surface 1011a and the inner surface 1012a of the vertical protrusion 1012, the remaining surfaces of the tongue 101 are separated from the groove wall 2011 of the tongue groove 201 by a certain gap D. In this way, the design size requirements for floor fasteners, especially the tongue and the tongue groove, are low, and it is convenient for the connection and assembly of male and female fasteners.

[0071] Of course, we can also arrange the full-area abutment of the part of the tongue extending into the tongue groove with the groove wall of the tongue groove, but this has higher requirements for the deformation ability of male and female fasteners.

[0072] In this embodiment, the first inclined surface 1021 and the second inclined surface 2021 are both planes. The angles between the first inclined surface 1021 and the second inclined surface 2021 of the planar structure and the horizontal plane should not be too large or too small. If the aforementioned angle is too large, the upward locking force on the first floor board a is insufficient, resulting in the first floor board a being prone to upward movement. If the aforementioned angle is too small, the head thickness at the bottom of the male buckle 1 and the female buckle 2 is relatively thin, and it is prone to fracture under vertical external force. Generally speaking, the aforementioned angle is preferably in the range of 30 - 85 degrees. In this embodiment, the angles between the first inclined surface 1021 and the horizontal plane and between the second inclined surface 2021 and the horizontal plane are both 75 degrees.

[0073] In this embodiment, the first horizontal surface 1011a is provided at the root of the tongue 101, and the second horizontal surface 2011a is provided at the notch of the tongue groove 201. In practical applications, the first horizontal surface 1011a mainly bears the upward pressure from the female buckle 2, and the second horizontal surface 2021a mainly bears the downward pressure from the male buckle 1. By providing the first horizontal surface 1011a at the root of the tongue 101, even if the first horizontal surface 1011a receives a large upward pressure, the tongue 101 will not undergo obvious deformation or fracture. Although the second horizontal surface 2011a is provided at the notch of the tongue groove 201, the female buckle part below the tongue groove has a relatively large thickness and can fully withstand a large downward pressure without obvious deformation or fracture.

[0074] In this embodiment, the first inclined surface 1021 extends all the way to the bottom of the male buckle 1, and the second inclined surface 2021 extends all the way to the bottom of the female buckle 2. In this way, although the abutting area between the first inclined surface 1021 and the second inclined surface 2021 can be increased, thereby enhancing the locking force of the male and female buckles in the horizontal and vertical directions, there are strict requirements for the manufacturing precision of the male and female buckles. Otherwise, it will be difficult to ensure that the three pairs of mating surfaces, namely the inner surface 1012a and the vertical sub-groove 2012, the first horizontal surface 1011a and the second horizontal surface 2011a, and the first inclined surface 1021 and the second inclined surface 2021, just perfectly abut after assembly. However, the following Embodiment 2 cleverly solves this problem.

[0075] In order to minimize the size and material consumption of the male and female buckles as much as possible, in this embodiment, the vertical protrusion 1012 is provided at the outer end of the tongue 101, and the vertical sub-groove 2012 is arranged as close as possible to the bottom of the tongue groove 201 - the inner groove wall surface 2012 of the vertical sub-groove 2012 is formed on the bottom wall 2011b of the tongue groove 201.

[0076] In this embodiment, the first floor board a and the second floor board b are not of the traditional wooden floor structure, but a composite structure composed of a lower honeycomb aluminum plate 4 and a marble panel 5 adhesively fixed on the upper surface of the honeycomb aluminum plate, specifically as follows:

[0077] The honeycomb aluminum plate 4 is composed of an upper aluminum plate 401, a lower aluminum plate 402 arranged parallel to the lower part of the upper aluminum plate, and an aluminum honeycomb core layer 403 fixedly connected between the upper aluminum plate and the lower aluminum plate. The area of the aluminum honeycomb core layer 403 is smaller than the areas of the upper aluminum plate 401 and the lower aluminum plate 402, and each side edge of the aluminum honeycomb core layer 403 is located inside the corresponding side edges of the upper aluminum plate 401 and the lower aluminum plate 402, so as to form a floor buckle embedding gap 4a around the aluminum honeycomb core layer 403 between the upper aluminum plate 401 and the lower aluminum plate 402. Each of the above floor buckles is embedded into the floor buckle embedding gap 4a. Moreover, the part of the floor buckle embedded into the floor buckle embedding gap 4a is adhesively fixed to the upper aluminum plate 401 and the lower aluminum plate 402.

[0078] The upper marble panel 5 can also be replaced with a board structure of other materials such as a wooden board, a ceramic tile board, a plastic board, etc.

[0079] It can be seen that in this embodiment, the male buckle 1 and the female buckle 2 as the floor buckles are not integrally formed with the main body part of the floor board. The male buckle 1 and the female buckle 2 detachably connected to the floor board main body can be made of various materials. In this embodiment, both the male buckle 1 and the female buckle 2 are made of aluminum alloy, and both of them are integrally formed parts. Further, the aforementioned male buckle 1 and female buckle 2 are both made of aluminum alloy profiles. In some other embodiments of the present application, the male buckle 1 and the female buckle 2 can also be integrally formed parts made of plastic material, and the two are respectively injection molded.

[0080] In some other embodiments of the present application, the male buckle 1 or the female buckle 2 can be integrally formed at the side position of the floor board, that is, the floor buckle can be integrally manufactured with the floor board and is of an integral structure. For example, the male buckle 1 or the female buckle 2 is a wooden structure integrally connected to the floor board main body.

[0081] In addition, in this embodiment, a sealing strip embedding groove 103 that is horizontally recessed inward is further provided above the tongue 101, and the lower side wall 1031 of the sealing strip embedding groove 103 is formed on the tongue 101, and a sealing strip 3 is embedded in the sealing strip embedding groove 103. When the male and female buckles are locked and matched, the sealing strip 3 embedded in the sealing strip embedding groove 103 is horizontally clamped between the male buckle 1 and the female buckle 2, so as to completely seal the matching gap between the male and female buckles and prevent water above the floor system from seeping downward through the gap at the connection and matching part of the floor boards into the lower part of the floor system.

[0082] Refer to again Figure 1 、 Figure 2 andFigure 4 As shown, in fact, on the side of the aforementioned first floor board a, not only the male snap 1 with the above structure is provided, but also the female snap 2 with the above structure is provided. The male snap and the female snap on the first floor board a are respectively arranged on different sides of the first floor board. Similarly, on the side of the second floor board b, not only the female snap 2 with the above structure is provided, but also the male snap 1 with the above structure is provided. The male snap and the female snap on the second floor board b are respectively arranged on different sides of the second floor board. In this way, a third floor board can be continuously connected to the left side of the first floor board a, and a fourth floor board can be connected to the right side of the second floor board b. Embodiment 2:

[0083] Figures 8 to 10 As shown in the second specific embodiment of the floor system of the present application, its structure is basically the same as that of Embodiment 1, and the main difference lies in:

[0084] In this embodiment, the first inclined surface 1021 does not extend all the way to the bottom of the male snap 1, and the second inclined surface 2021 does not extend all the way to the bottom of the female snap 2.

[0085] Through Embodiment 1, we know that: the male snap 1 has its own surface structure, and a part of the surface 102 of the male snap 1 is under the tongue 101, and the first inclined surface 1021 is not only a part of the surface of the male snap, but also under the tongue 101.

[0086] In this embodiment, all the surfaces 102 of the male snap 1 that are under the tongue 101 except the first inclined surface 1021 are arranged with a gap D from the surface 202 of the female snap 2.

[0087] Compared with Embodiment 1, in this embodiment, the first inclined surface 1021 and the second inclined surface 2021 are designed to be shorter, which is more conducive to the manufacture and assembly of the male and female snaps.

[0088] The above is only an exemplary implementation manner of the present application, rather than being used to limit the protection scope of the present application. The protection scope of the present application is determined by the appended claims.
