[0036] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0037] 1, 2 and 3, an embodiment of the present invention provides a fastener for connecting a floor 1 to a keel 2. 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. The fastener 3 includes a limiting base 31 that can rotate freely within the limiting groove 21 and a fastening member 32 for connecting to the floor 1. The fastening member 32 is provided on the limiting base 31.

[0038] 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 provided on one side of the fastening groove 321 ;

[0039] The limiting base 31 includes a base plate 311 that can pass through the limiting opening 23 and extended edges 312 provided 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 below the limiting edges 22.

[0040] Specifically, referring to FIG1 , the buckling groove body 321 includes a main buckling end 3211 and a secondary buckling end 3212 , and a buckling groove for connecting to the floor 1 is formed between the main buckling end 3211 and the secondary buckling end 3212 ;

[0041] The main and secondary snap-fit ​​ends 3211, 3212 are each provided with an elastic snap-fit ​​edge 3213 for snap-fit ​​connection. The elastic snap-fit ​​edge 3213 is tilted downwardly into the snap-fit ​​groove to secure the inverted T-shaped component. The snap-fit ​​groove body 321 is an integrated structure and is made of a material with a certain degree of elastic deformation, such as plastic or rubber.

[0042] 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.

[0043] To further securely connect the fasteners 3 at the floor's edge to the keel 2 and limit overall floor deflection, the base plate 311 is provided with connection holes 3111 for connecting to the keel 2. Therefore, depending on actual installation requirements, additional bolts can be used to secure the fasteners 3 to the keel 2, ensuring a secure connection.

[0044] Furthermore, both sides of the main fastening end 3211 and the auxiliary fastening end 3212 are provided with notches 3214 through which the limiting edge 22 can pass. The provision of the notches 3214 prevents the length design of the main fastening end 3211 and the auxiliary fastening end 3212 from being restricted by the limiting edge 22, thereby allowing the length of the main fastening end 3211 and the auxiliary fastening end 3212 to be extended according to actual needs, thereby improving the fastening force between the main fastening end 3211 and the auxiliary fastening end 3212 and the floor 1.

[0045] Referring to FIG2 , an embodiment of the present invention provides a chassis for installing a floor, comprising a plurality of support assemblies for supporting the installation of a floor 1, wherein the support assemblies include a keel 2 and a fastener 3. 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 the same as that shown in FIG1 , and its structural principle will not be repeated here.

[0046] The bottom surface of the retaining groove 21 is provided with a connecting groove 24 for threaded connection, and the base plate 311 is provided with a connecting hole 3111 corresponding to the connecting groove. Therefore, when the connection between the fastener 3 and the keel 2 requires further reinforcement, a bolt connection can be used. Preferably, the width of the connecting groove 24 is between the outer and inner diameters of the bolt to facilitate the insertion of the bolt. Preferably, the keel 2 is made of aluminum profile, so that conventional bolts can be threaded into the threaded connection.

[0047] Correspondingly, referring to Figures 3 and 4, an embodiment of the present invention provides a spliced ​​floor, including a base frame and a floor 1 laid on the base frame. The structure of the base frame is the same as the corresponding structure shown in Figures 1 and 2, and its structural principles are not described here one by one.

[0048] The floor panel 1 is provided with a buckling portion 11 for buckling into the buckling groove 321 and a pressing portion 12 for pressing the pressing edge 322 at both ends. Preferably, the buckling portion 11 is in an inverted T shape.

[0049] The buckling groove body 321 includes a main buckling end 3211 and a secondary buckling end 3212, and a buckling groove for connecting to the floor 1 is formed between the main buckling end 3211 and the secondary buckling end 3212;

[0050] 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 snapping into the snap-fit ​​groove.

[0051] One end of the pressing edge 322 is provided with a lower convex edge 3221 for preventing lateral movement of objects. 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 snap into. The provision of the lower convex edge 3221 can effectively prevent horizontal movement of the floor panels 1, thereby stabilizing the splicing between adjacent floor panels 1.

[0052] Furthermore, one side of the fastening portion 11 is provided with an inner concave surface 11a for the elastic fastening edge 3213 to snap into, and the other side is provided with an inclined surface 11b for guiding the fastening portion 11 out of the fastening groove so as to abut against the other elastic fastening edge 3213. The provision of the inclined surface 11b prevents both ends from completely snapping onto the fastening portion 11, while providing a certain stable fastening force and making it easier for the loading and unloading personnel to lift the floor panel 1 from one end of the inclined surface 11b for convenient disassembly.

[0053] 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 pressure 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.

[0054] The placement of the fasteners 3 creates gaps between adjacent floorboards 1, exposing the fasteners 3. This makes the floorboards 1 unsightly and increases the likelihood of damage from external factors. Therefore, shielding edges 13 are provided on both sides of the floorboards 1, located above the fastening portions 11 and the pressing edges 322. Between two adjacent floorboards 1, the shielding edges of one floorboard 1 intersect with the shielding edges of the other floorboard 1 to shield the fastening portions 11, the pressing edges 322, and the space between them.

[0055] 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.

[0056] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
