[0028] A rubber sleeve mechanism 9 is sleeved on the outer side of the limiting column 2, and the rubber sleeve mechanism 9 is placed on the support seat 1. Both ends of the connecting pipe 8 extend into the rubber sleeve mechanism 9. A pressure plate 10 is sleeved on the outer side of the limiting column 2, and the pressure plate 10 is placed on the rubber sleeve mechanism 9. The outer side of the external thread 3 is threadedly connected with a pressure cap 12. A groove 11 is opened on the upper end surface of the pressure plate 10, and the pressure cap 12 passes through the groove 11.

[0029] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the top of the extrusion column 6 is movably connected with a ball 7, four balls 7 are provided, and the four balls 7 are evenly distributed on the extrusion column 6 in the circumferential direction. When the pressure cap 12 is screwed downward, the pressure cap 12 squeezes the extrusion column 6 and the piston 5 to move downward. At this time, the ball 7 rolls, which facilitates reducing the friction between the pressure cap 12 and the extrusion column 6.

[0030] In this embodiment, Figure 2 and Figure 5 As shown, the rubber sleeve mechanism 9 includes a rubber sleeve body 901, and the rubber sleeve body 901 is placed on the outside of the limiting column 2, the rubber sleeve body 901 is placed on the support seat 1, and the pressure plate 10 is placed on the rubber sleeve body 901. The support seat 1 supports the rubber sleeve body 901, and the limiting column 2 limits the rubber sleeve body 901. After the two paving slabs are connected together using the rubber sleeve body 901, the pressure plate 10 can be placed.

[0031] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, a buffer channel 902 is provided on the rubber sleeve body 901. The buffer channel 902 makes the rubber sleeve body 901 hollow, thereby improving the buffering effect of the rubber sleeve body 901 to achieve the purpose of protection.

[0032] In this embodiment, Figure 2 , Figure 4 and Figure 6 As shown, the second airtight channels 903 are symmetrically opened on both sides of the bottom of the rubber sleeve body 901 , and the connecting pipe 8 extends into the head end of the second airtight channel 903 , and the connecting pipe 8 serves to connect the first airtight channel 4 and the second airtight channel 903 .

[0033] In this embodiment, Figure 2 , Figure 4 and Figure 6 As shown, an annular groove 904 is provided on the outer side of the rubber sleeve body 901, and the annular groove 904 is connected with the end of the second airtight channel 903, and an annular airbag 905 is fixed in the annular groove 904, and the annular airbags 905 are evenly spaced on the rubber sleeve body 901. When the rubber sleeve body 901 is used to connect two paving slabs together, the rubber sleeve body 901 extends into the connecting holes of the two paving slabs. When air is pressed into the annular groove 904, the annular airbag 905 automatically expands and presses against the connecting holes of the two paving slabs, which facilitates the role of strengthening the connection and makes the splicing and assembly effect tighter and firmer.

The elastic cord 906 serves to connect the annular airbag 905 and the rubber sleeve body 901. When the annular airbag 905 is expanded, the elastic cord 906 is stretched. When the cap 12 is turned on, the elastic cord 906 pulls the annular airbag 905 back into the annular groove 904 to facilitate the subsequent smooth disassembly of the rubber sleeve body 901. When the expanded annular airbag 905 is used to strengthen the connection between the two paving slabs, the anti-skid protrusion 907 made of rubber material can increase the friction, which is convenient for strengthening the connection between the annular airbag 905 and the wall of the connecting hole of the paving slab.

One side of the push block 16 is connected to a locking block 18 by a connecting rope 17, and the locking block 18 is connected to an inner wall of the pressure plate 10 by a compression spring 19. After the pressure cap 12 is screwed down to the bottom, the locking block 18 will automatically be stuck in the slot 14 under the action of the compression spring 19, which is convenient for locking the pressure cap 12. When the push block 16 is manually pushed to the left, the locking block 18 will move and leave the slot 14 under the pulling action of the connecting rope 17, which is convenient for unlocking the pressure cap 12.

[0037] The use method and advantages of the present invention: The paving slab connector that is convenient for replacing rubber sleeves has the following working process: like Figures 1 to 6 As shown: first, install the support seat 1 on the ground, put the two paving slabs together and let the limit column 2 pass through the connecting holes on the two paving slabs, then insert the rubber sleeve body 901 into the connecting holes on the two paving slabs and let the limit column 2 pass through the rubber sleeve body 901, then put the pressing plate 10 on the rubber sleeve body 901, insert the external hexagonal wrench into the hexagonal groove 13 and screw the pressing cap 12 to press the pressing plate 10, the pressing plate 10 presses and fixes the rubber sleeve body 901, after the pressing cap 12 is screwed to the bottom, the locking block 18 is automatically stuck in the slot 14, thereby locking the pressing cap 12, and in the process of screwing down the pressing cap 12, the pressing cap 12 squeezes the squeezing column 6 and the piston 5 to move downward, The annular airbag 905 automatically expands and presses against the connecting holes on the two paving slabs, thereby strengthening the connection. The anti-skid protrusion 907 can increase the friction. A buffer channel 902 is provided on the rubber sleeve body 901, which can enhance the buffering performance of the rubber sleeve body 901. If the rubber sleeve body 901 needs to be replaced, the push block 16 is manually pushed to the right. The locking block 18 moves to the left and leaves the slot 14 under the pulling action of the connecting rope 17, thereby unlocking the pressing cap 12. Then the pressing cap 12 is screwed up, and the elastic rope 906 pulls the annular airbag 905 back into the annular groove 904. After removing the pressing plate 10, the rubber sleeve body 901 can be removed for replacement.
