[0035] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 , 2 3. The embodiment of the utility model provides a fastener for connecting a floor 1 and a keel 2. The keel 2 is provided with a limiting groove 21. The notch of the limiting groove 21 is provided with a limiting edge 22 to form a limiting opening 23. The fastener 3 includes a limiting base 31 that can rotate freely in the limiting groove 21 and a fastening member 32 for connecting with the floor 1. The fastening member 32 is provided on the limiting base 31.

[0037] The fastening member 32 includes a fastening groove 321 and a pressing edge 322 for fastening the floor 1, and the pressing edge 322 is arranged on one side of the fastening groove 321;

[0038] The limiting base 31 includes a base plate 311 that can pass through the limiting opening 23 and extended edges 312 arranged on both sides of the base plate 311, so as to limit the limiting base 31 from leaving the limiting groove 21 when the extended edges 312 are rotated to the bottom of the limiting edges 22.

[0039] Specifically, see Figure 1 The buckling groove body 321 includes a main buckling end 3211 and a secondary buckling end 3212, and a buckling groove for connecting the floor 1 is formed between the main buckling end 3211 and the secondary buckling end 3212;

[0040] The main buckle end 3211 and the auxiliary buckle end 3212 are both provided with elastic buckle edges 3213 for buckle connection, and the elastic buckle edges 3213 are arranged downwardly and inclined in the buckle groove to buckle the inverted T-shaped component. The buckle groove body 321 is an integrated structure and is made of a material with certain elastic deformation, such as plastic, rubber, etc.

[0041] Furthermore, a lower convex edge 3221 for preventing lateral movement of an object is provided at one end of the pressing edge 322, and the surface of the lower convex edge 3221 is an arc surface.

[0042] In order to further fix the fasteners 3 at the edge of the floor with the keel 2 to limit the deviation of the entire floor, the base plate 311 is provided with a connection hole 3111 for connecting the keel 2. Therefore, according to the actual paving requirements, for the fasteners 3 that need to be firmly connected to the keel 2, bolt connection can be additionally adopted to cooperate with the connection hole 3111 to complete the firm connection.

[0043] Moreover, both sides of the main buckling end 3211 and the auxiliary buckling end 3212 are provided with a notch 3214 for the limiting edge 22 to pass through. The provision of the notch 3214 can avoid the length design of the main buckling end 3211 and the auxiliary buckling end 3212 being limited by the limiting edge 22, and then the length of the main buckling end 3211 and the auxiliary buckling end 3212 can be extended according to actual needs to improve the buckling force between the floor 1.

[0044] See also Figure 2 The embodiment of the utility model provides a base frame for installing a floor, including a plurality of support components for supporting the installation of the floor 1, wherein the support components include a keel 2 and a fastener 3, wherein the keel 2 is provided with a limiting groove 21, and the notch of the limiting groove 21 is provided with a limiting edge 22 to form a limiting opening 23. Therefore, the connection between the fastener 3 and the keel 2 can be achieved by rotating the limiting base 31 so that the extended edge 312 is rotated to the bottom of the limiting edge 22, thereby completing the quick installation between the keel 2 and the fastener 3. Similarly, when disassembly is required, the limiting edge 22 can be rotated to the limiting opening 23. Accordingly, the width of the limiting edge 22 is smaller than the width of the limiting opening 23. The structural principle of the fastener 3 is similar to Figure 1 The same as shown, the structural principles are not described here one by one.

[0045] The bottom surface of the limiting groove 21 is provided with a connection groove 24 for threaded connection, and the base plate 311 is provided with a connection hole 3111 corresponding to the connection groove. Therefore, when the connection between the fastener 3 and the keel 2 needs to be further reinforced, a bolt connection can be used for connection. Preferably, the width of the connection groove 24 is between the outer diameter and the inner diameter of the bolt, so that the bolt can be tapped in. Preferably, the keel 2 is an aluminum profile, so that the existing conventional bolts can be tapped into the thread to complete the threaded connection.

[0046] Accordingly, see Figure 3 and Figure 4 The utility model provides a spliced ​​floor, including a base frame and a floor 1 laid on the base frame, wherein the structure of the base frame is Figure 1 and Figure 2 , the corresponding structures shown are the same, and their structural principles are not described here one by one.

[0047] The two side ends of the floor 1 are provided with a buckling portion 11 for buckling into the buckling groove 321 and a pressing portion 12 for pressing the pressing edge 322. Preferably, the buckling portion 11 is in an inverted T shape.

[0048] The buckling groove body 321 includes a main buckling end 3211 and a secondary buckling end 3212, and a buckling groove for connecting the floor 1 is formed between the main buckling end 3211 and the secondary buckling end 3212;

[0049] The main snap-fit ​​end 3211 and the auxiliary snap-fit ​​end 3212 are both provided with elastic snap-fit ​​edges 3213 for snap-fit ​​connection. The elastic snap-fit ​​edges 3213 are arranged to be inclined downward into the snap-fit ​​groove to facilitate the snap-fit ​​part 11 to squeeze open the elastic snap-fit ​​edges 3213 on both sides when it is snapped into the snap-fit ​​groove.

[0050] One end of the pressing edge 322 is provided with a lower convex edge 3221 for preventing an object from moving sideways, and the pressing portion 12 is provided with an inner concave surface 11a adapted to the lower convex edge 3221 for the lower convex edge 3221 to be buckled in. The setting of the lower convex edge 3221 can effectively prevent the horizontal movement of the floor 1, thereby stabilizing the splicing between adjacent floorboards 1.

[0051] Furthermore, one side of the buckling part 11 is provided with an inner concave surface 11a for the elastic buckling edge 3213 to buckle into, and the other side is provided with an inclined surface 11b for guiding the buckling part 11 to disengage from the buckling groove, so as to allow the other elastic buckling edge 3213 to collide. The provision of the inclined surface 11b can avoid the situation where both ends completely buckle the buckling part 11, and while providing a certain stable buckling force, it is convenient for loading and unloading personnel to lift up the floor 1 from one end of the inclined surface 11b to achieve the function of convenient disassembly.

[0052] Therefore, during the installation of the floor 1, one end of the floor 1 is connected to the keel 2 by snapping the snap-fit ​​portion 11 into the snap-fit ​​groove, and the other end is restricted by the downward pressure of the pressing edge 322 of the upper fastener 3, thereby achieving a structural relationship in which both ends of the floor 1 are connected to the keel 2.

[0053] The arrangement of the fasteners 3 will cause gaps between adjacent floorboards 1 and expose the fasteners 3, making the floorboards 1 unsightly and the exposure of the fasteners 3 increases the probability of damage by external factors. Therefore, shielding edges 13 are respectively provided at both ends of the floorboards 1, and the shielding edges 13 on both sides are respectively located above the buckling portion 11 and the pressing edge 322; between two adjacent floorboards 1, the shielding edge of one floorboard 1 is interlaced with the shielding edge of the other floorboard 1 to shield the buckling portion 11, the pressing edge 322 and the space between them.

[0054] Preferably, a plurality of supporting portions 13 corresponding to the buckling portions 11 and the pressing portions 12 are provided at the bottom of the floor 1 to jointly support the floor.

[0055] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
