The rear side is inclined toward the lower sleeve groove 3, and a semicircular thickened elastic pad 7 is fixedly connected to the front side of the central sleeve shaft 4 in the lower sleeve groove 3. The left and right inner walls of the lower sleeve groove 3 are fixedly connected with inclined elastic pads 8 in the form of straight triangular prisms. The inclined surfaces of the two inclined elastic pads 8 correspond to each other and the front side is inclined toward the upper sleeve groove 2. A groove is formed on one side of the thickened elastic pad 7 that fits the central sleeve shaft 4, and a groove is formed on one side of the inclined elastic pad 8 that fits the lower sleeve groove 3. The thickened elastic pad 7 and the inclined elastic pad 8 are both filled with hydraulic oil, and the thickness of the thickened elastic pad 7 and the inclined elastic pad 8 is slightly larger than the thickened protrusion 5 and the inclined protrusion 6.

[0023] A filling through hole 9 is provided at the center of the top surface of the buckle body 1 .

[0024] A plurality of semi-tooth-shaped through holes 10 are formed at equal intervals on both sides of the buckle body 1 from top to bottom.

[0025] A mountain-shaped connecting groove 11 is provided inside the buckle body 1 between several semi-toothed through holes 10, and the connecting groove 11 is located in front of the filling through hole 9. The three end notches of the connecting groove 11 are respectively connected to the thickened elastic pad 7 and the two inclined elastic pads 8. A fixing groove 12 is provided on the right side of the buckle body 1, and an expansion pad 13 is fixedly connected to the inner wall of the fixing groove 12. An elastic plate 14 is fixedly connected to the upper and lower inner walls on the right side of the fixing groove 12, and the left side of the elastic plate 14 is fitted with the expansion pad 13, and the expansion pad 13 is connected to the connecting groove 11, and the expansion pad 13 is filled with hydraulic oil.

[0026] A hollow collar 15 is fixedly connected to the inner wall of the filling through hole 9, and an annular pad 16 is sleeved on the outer wall of the collar 15. A hole is opened along the wall surface of the collar 15. The right outer wall of the annular pad 16 is fixedly connected and connected with a connecting pipe 17. The connecting pipe 17 runs through the buckle body 1 and is fixedly connected and connected with the expansion pad 13. The front outer wall of the annular pad 16 is fixedly connected and connected with a connecting pipe 2 18. The connecting pipe 2 18 runs through the buckle body 1 and is connected with the connecting groove 11. The annular pad 16 is filled with hydraulic oil, and the expansion pad 13 is connected with the connecting groove 11 through the annular pad 16, the connecting pipe 17 and the connecting pipe 2 18.

[0027] When in use, first, a groove is opened on the floor with a shape and size that is suitable for the combination of the upper sleeve groove 2, the center sleeve shaft 4, the thickened protrusion 5 and the inclined protrusion 6, and the depth of the groove is half of the width of the buckle body 1. Then, according to the required size, the buckle body 1 is broken into the required length through the semi-toothed through hole 10, and then the upper sleeve groove 2 and the lower sleeve groove 3 are respectively inserted into the slots on the two floors. The protrusions of the thickened protrusion 5, the inclined protrusion 6, the thickened elastic pad 7 and the inclined elastic pad 8 are engaged with the grooves on the floor, so that the buckle body 1 can only slide in the slot on the floor, thereby completing the splicing of the two floors. Then, fillers such as foam glue can be filled in the filling through hole 9, and the expansion force generated during the filling of the filler causes the buckle body 1 to deform, thereby further increasing the strength of the engagement between the buckle body 1 and the floor, and increasing the stability of the floor splicing.

[0028] In the actual operation process, the usual operation process is to first insert the buckle body 1 into the floor set on the ground, and then insert another floor into the other side of the buckle body 1. Therefore, first insert the side of the buckle body 1 corresponding to the lower insertion groove 3 into the floor, and use the deformable ability of the thickened elastic pad 7 and the inclined elastic pad 8 and the setting that is larger than the size of the thickened protrusion 5 and the inclined protrusion 6. After the side of the buckle body 1 corresponding to the lower insertion groove 3 is first inserted into the floor, the thickened elastic pad 7 and the inclined elastic pad 8 generate a large friction with the inner wall of the slot on the floor, thereby The position of the buckle body 1 is stabilized, which is convenient for the subsequent floor connection. The buckle body 1 will not move and cause position deviation when subjected to force. In addition, when the side of the buckle body 1 corresponding to the lower part of the slot 3 is connected to the floor, the buckle body 1 is directly inserted into the slot on the floor. The thickened elastic pad 7 and the inclined elastic pad 8 are subjected to force and the hydraulic oil inside is injected into the expansion pad 13, thereby contracting to adapt to the slot on the floor. After the thickened elastic pad 7 and the inclined elastic pad 8 enter the slot on the floor, the thickened elastic pad 7 and the inclined elastic pad 8 rebound by themselves. The elastic pad 14 rebounds and injects hydraulic oil back into the thickened elastic pad 7 and the inclined elastic pad 8. The thickened elastic pad 7 and the inclined elastic pad 8 are filled with liquid and expanded to engage with the slots on the floor, so that the operation of inserting the buckle body 1 with the bottom plate set on the ground is more convenient and quick, avoiding the problem of reduced efficiency caused by sliding insertion and the problem of sliding difficulty caused by the large friction between the thickened elastic pad 7, the inclined elastic pad 8 and the slots on the floor. When another floor is inserted into the buckle body 1, the inner wall of the slot of the other floor is attached to the elastic pad 14, so that The expansion pad 13 will not expand to accommodate the hydraulic oil in the thickened elastic pad 7 and the inclined elastic pad 8, so that the thickened elastic pad 7 and the inclined elastic pad 8 remain in a liquid-filled and expanded state to stabilize the connection with the floor. In addition, when the filler is filled in the filling hole 9, the filler is squeezed on the annular pad 16 through the ring 15. The annular pad 16 is deformed by force to seal the internal space, thereby cutting off the connection between the connecting pipe 17 and the connecting pipe 2 18, further ensuring that the thickened elastic pad 7 and the inclined elastic pad 8 will not be detached from the slot on the floor due to the discharge of hydraulic oil due to force.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
