[0056] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0057] Figure 1 It is a schematic diagram of the structure of the connecting buckle of the quick-install floor combination according to an embodiment of the present invention; Figure 6 It is according to Figure 4 Enlarged schematic view of area D; Figure 8 It is a schematic diagram of the arc groove and the limiting block in the connecting buckle of the quick-install floor combination according to an embodiment of the present invention. In Figure 1 , Figure 6 and Figure 8 , the connecting buckle may include a locking part 8, an arc groove 15, a pressing plate part, and a rotating rod 4. Specifically, the locking part 8 may include a first cylindrical groove, and the pressing plate part may include a column body, a sleeve ring 17, and a clamping component. Specifically, the sleeve ring 17 may include a limiting block 16.

[0058] The locking part 8 is arranged inside the keel and is used for clamping cooperation with the keel. A first cylindrical groove is opened at the top end of the locking part 8, and an arc groove 15 is opened on the inner wall of the first cylindrical groove. The bottom end of the column body extends into the first cylindrical groove, and a collar 17 is fixedly sleeved on the side wall of the column body. A limiting block 16 is arranged on the side wall of the collar 17, and the limiting block 16 extends into the arc groove 15. The clamping component is arranged at the top of the column body and is vertically distributed with the locking part 8, and is used for making way for the quick-install floor when the quick-install floor is disassembled to assist the removal of the quick-install floor. The rotating rod 4 movably penetrates through the clamping component and the column body and is fixedly connected with the locking part 8.

[0059] When installing and fixing two adjacent quick-install floors, extend the locking part 8 into the notch of the keel. At this time, the clamping component is parallel to the adjacent quick-install floor. Drive the rotating rod 4 to rotate along one of the circumferential directions to drive the locking part 8 to rotate. Specifically, the way to drive the rotating rod 4 can include opening a plum blossom groove on the top of the rotating rod 4, etc., and using a tool matching with the plum blossom groove, etc. to drive it to rotate. When rotating along one of the circumferential directions, the limiting block 16 abuts against one end of the arc groove 15, that is, during the process of the locking part 8 driving the arc groove 15 to rotate, the limiting block 16 is pushed to rotate synchronously, that is, the column body and the clamping component are driven to rotate synchronously. During this process, the clamping component and the locking part 8 always maintain a vertically distributed state, so as to achieve the purpose of locking the locking part 8 with the inner wall of the keel and limiting and fixing the adjacent quick-install floor by the clamping component. When disassembling two adjacent quick-install floors, drive the rotating rod 4 to rotate along the other circumferential direction. At this time, the limiting block 16 gradually moves away from one end of the arc groove 15 and gradually approaches the other end of the arc groove 15, that is, the clamping component does not rotate along with it and still remains in the state of limiting the quick-install floor, while the locking part 8 is disengaged from the locking state with the keel. After reversely rotating the connecting buckles on the opposite sides of the quick-install floor, the staff pries open the quick-install floor, and the clamping component makes way for the quick-install floor to assist it to disengage from its original position to achieve disassembly, but the connecting buckles still remain in their original positions to limit the quick-install floor adjacent to this quick-install floor.

[0060] When disassembling traditional quick-installation floors, it is necessary to first disassemble the connection buckles on the opposite sides of the floor so that the floor can be disengaged and then disassembled and replaced. However, this method will cause one of the adjacent quick-installation floors to lose its limit, making it easy to shift and misalign during the process of replacing the floor, that is, the stability is reduced. Secondly, when replacing the floor, it is necessary to manually fix the floor while tightening the connection buckle, which is difficult to operate and results in low installation efficiency. In this embodiment of the present utility model, a structure in which the arc groove 15 and the limit block 16 cooperate is adopted, so that when the rotating rod 4 rotates along one of the circumferential directions, the locking portion 8 and the clamping assembly rotate synchronously. Conversely, the locking portion 8 can be disengaged from the lock, and the clamping assembly continues to be in the state of limiting the quick-installation floor. At the same time, it can also make way to assist the reliable removal of the quick-installation floor, with simple operation and no impact on the stability of adjacent floors. Similarly, when replacing the quick-installation floor, the clamping assembly is driven to make way for the new quick-installation floor until the new quick-installation floor is installed in place. At this time, the clamping assembly re-limits and fixes the new quick-installation floor, so that it is not necessary for the staff to additionally fix the new quick-installation floor to tighten the connection buckle, which is more convenient and fast, and improves the installation efficiency and effect.

[0061] In this embodiment of the present utility model, the size of the arc angle of the arc groove 15 can be in various forms known to those skilled in the art. However, considering the convenience of replacing and disassembling the connection buckle, the arc angle of the arc groove 15 is greater than 90°, that is, the locking portion 8 can be rotated to a state parallel to the clamping assembly, so as to facilitate the movement or removal of the connection buckle.

[0062] In this embodiment of the present utility model, considering the stability and reliability of the cooperation and drive between the arc groove 15 and the limit block 16, the number of the arc groove 15 and the limit block 16 can be as Figure 8 shown. Specifically, in Figure 8 , the number of the arc groove 15 and the limit block 16 can include two groups and are symmetrically distributed along the collar 17.

[0063] In this embodiment of the present utility model, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 shown, the clamping assembly can include a main board body 3, two sub-board bodies 1, two rotating shafts 11 and a plurality of torsion springs 10. Specifically, the main board body 3 can include a groove, and the sub-board body 1 can include a convex portion 2.

[0064] The main board body 3 is arranged at the top of the column body, and grooves 9 are formed at two opposite ends of the main board body 3. Two sub-board bodies 1 are respectively arranged at two opposite ends of the main board body 3. A convex portion 2 is arranged at one end of the sub-board body 1 close to the main board body 3, and the convex portion 2 extends into the corresponding groove 9. A rotating shaft 11 is fixedly passed through the corresponding convex portion 2 and is rotatably connected to the inner wall of the corresponding groove 9. A plurality of torsion springs 10 are respectively sleeved outside the two rotating shafts 11. One end of the torsion spring 10 is connected to the main board body 3, and the other end of the torsion spring 10 is connected to the sub-board body 1.

[0065] When disassembling the quick-install floor, the quick-install floor pushes the corresponding sub-board body 1 to rotate upward, that is, the convex portion 2 rotates along the corresponding rotating shaft 11 to make way for the quick-install floor and assist its displacement. When a new quick-install floor needs to be installed, the sub-board body 1 is driven to rotate upward to make way. After the new quick-install floor enters, the sub-board body 1 is released, and the torsion spring 10 drives the sub-board body 1 to reset and limit and fix the new quick-install floor, and then the connection buckle is fastened. By adopting the connection method of connecting the sub-board body 1 and the main board body 3 through the torsion spring 10, the purpose of the sub-board body 1 assisting in making way when disassembling the quick-install floor can be realized, which is more convenient and fast, and does not affect the state of limiting and fixing adjacent quick-install floors synchronously.

[0066] In this embodiment of the present utility model, considering that the quick-install floor will give an upward acting force to the sub-board body 1 when disassembling, if the locking portion 8 is in a locked state with the inner wall of the keel, there is a situation where the limiting block 16 is broken under the action of stress. Therefore, in this application, the locking portion 8 is first driven to disengage from the locked state with the keel, reducing the risk of the limiting block 16 breaking, and thus improving the service life of the connection buckle.

[0067] In this embodiment of the present utility model, as Figure 7 shown, the clamping assembly may further include two fixing plates 14 and a plurality of clamping convex points 12. Specifically, the fixing plate 14 may include a plurality of clamping concave points 13.

[0068] The fixing plate 14 is arranged near the bottom of the corresponding groove 9, and a plurality of clamping concave points 13 are formed on the fixing plate 14. A plurality of clamping convex points 12 are arranged at the bottom end of the convex portion 2 and are clamped with the corresponding clamping concave points 13.

[0069] The cooperation of the clamping convex points 12 and the clamping concave points 13 can further improve the stability of the sub-board body 1 in limiting and fixing the quick-install floor, and avoid the situation where the quick-install floor warps when subjected to uneven external forces. In addition, the fixing plate 14 can also limit the rotation direction of the sub-board body 1 to only rotate upward.

[0070] In this embodiment of the present utility model, as Figure 4 and Figure 5As shown, the cylinder may include a first connecting column 5, a second connecting column 6, a spring 20, and a limiting component. Specifically, the first connecting column 5 may include a second cylindrical groove 18, and the second connecting column 6 may include a third connecting column 19.

[0071] A second cylindrical groove 18 is formed at the bottom end of the first connecting column 5. A third connecting column 19 is provided at the top end of the second connecting column 6, and the third connecting column 19 extends into the interior of the second cylindrical groove 18. The spring 20 is sleeved outside the third connecting column 19. One end of the spring 20 is connected to the third connecting column 19, and the other end of the spring 20 is connected to the inner wall of the second cylindrical groove 18. The limiting component is arranged on the first connecting column 5 and the second connecting column 6 and is used to limit that the first connecting column 5 and the second connecting column 6 can only move closer to or away from each other.

[0072] The first connecting column 5 and the second connecting column 6 are connected by the spring 20, and the limiting component enables them to only move closer to or away from each other. This structure can, on the one hand, improve the stability of the two auxiliary plate bodies 1 for limiting and fixing the quick-install floor, and on the other hand, can also provide corresponding redundant assistance when the quick-install floor expands and contracts due to heat, avoiding the occurrence of situations such as cracking of the quick-install floor, and thus effectively protecting the quick-install floor.

[0073] In this embodiment of the present invention, as Figure 4 and Figure 5 shown, the limiting component may include a plurality of movable grooves 21 and a plurality of movable rods 7. Specifically, a plurality of movable grooves 21 are formed at the bottom end of the first connecting column 5, and a plurality of movable rods 7 are provided at the top of the second connecting column 6 and extend into the corresponding movable grooves 21 respectively.

[0074] On the other hand, the present invention also provides a quick-install floor combination. Specifically, the quick-install floor combination may include a plurality of keels, a plurality of quick-install floor bodies, and connecting buckles. Specifically, the connecting buckle may include a locking portion 8, an arc groove 15, a pressing plate portion, and a rotating rod 4. Specifically, the locking portion 8 may include a first cylindrical groove, and the pressing plate portion may include a cylinder, a collar 17, and a clamping component. Specifically, the collar 17 may include a limiting block 16.

[0075] Multiple quick - installation floor bodies are arranged on multiple keels and are horizontally and vertically staggered with the keels. The locking part 8 is arranged inside the keel and is used for clamping and engaging with the keel. A first cylindrical groove is opened at the top end of the locking part 8, and an arc groove 15 is opened on the inner wall of the first cylindrical groove. The bottom end of the column body extends into the first cylindrical groove, and the collar 17 is fixedly sleeved on the side wall of the column body. A limiting block 16 is arranged on the side wall of the collar 17, and the limiting block 16 extends into the arc groove 15. The clamping component is arranged at the top of the column body and is vertically distributed with the locking part 8, and is used for making way for the quick - installation floor when the quick - installation floor is disassembled to assist in moving out the quick - installation floor. The rotating rod 4 movably penetrates through the clamping component and the column body and is fixedly connected with the locking part 8.

[0076] When installing and fixing two adjacent quick - installation floors, extend the locking part 8 into the notch of the keel. At this time, the clamping component is parallel to the adjacent quick - installation floor. Drive the rotating rod 4 to rotate along one of the circumferential directions to drive the locking part 8 to rotate. Specifically, the way to drive the rotating rod 4 can include opening a plum - blossom groove at the top of the rotating rod 4, etc., and using a tool that cooperates with the plum - blossom groove, etc. to drive its rotation. When rotating along one of the circumferential directions, the limiting block 16 abuts against one end of the arc groove 15. That is, during the process of the locking part 8 driving the arc groove 15 to rotate, the limiting block 16 is pushed to rotate synchronously, that is, driving the column body and the clamping component to rotate synchronously. During this process, the clamping component and the locking part 8 always maintain a vertically distributed state, so as to achieve the purpose of locking the locking part 8 with the inner wall of the keel and the clamping component limiting and fixing the adjacent quick - installation floor. When disassembling two adjacent quick - installation floors, drive the rotating rod 4 to rotate along the other circumferential direction. At this time, the limiting block 16 gradually moves away from one end of the arc groove 15 and gradually approaches the other end of the arc groove 15. That is, the clamping component does not follow the rotation and still remains in the state of limiting the quick - installation floor, while the locking part 8 is disengaged from the locking state with the keel. After reversely rotating the connection buckles on the opposite sides of the quick - installation floor, the staff pries open the quick - installation floor, and the clamping component makes way for the quick - installation floor to assist it in moving out of its original position to achieve disassembly, but the connection buckles still remain in place to limit the adjacent quick - installation floor of the quick - installation floor.

[0077] Through the above technical solution, when the quick - installation floor combination and its connection buckle provided by the utility model fix adjacent quick - installation floors, extend the locking part 8 into the keel, and rotate the pressing plate part. The limiting block 16 abuts against one end of the arc groove 15, and drive the rotating rod 4 to rotate along one of the circumferential directions, and the limiting block 16 and the pressing plate part can be driven to rotate synchronously through the arc groove 15; when disassembling the quick - installation floor, drive the rotating rod 4 to rotate along the other circumferential direction, the arc groove 15 follows the rotation, and the limiting block 16 is not subjected to the driving force, that is, only the locking part 8 rotates until the locking part is disengaged from the locking state with the keel. At this time, the floor can be disassembled and the clamping component can make way to assist the floor to move out. The operation is simple and will not affect the stability of the adjacent floors.

[0078] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solution of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.
