DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] Reference Figure 1-4A high and low grade concrete interception device includes an air bag 1 and a connecting block 2 11. The top of the air bag 1 is fixedly connected to the air pipe 2. The outer edge of the air bag 1 is fixedly installed with a Velcro 1 8. The outer edge of the Velcro 1 8 is adhered with a Velcro 2 9. The side of the Velcro 2 9 away from the Velcro 1 8 is fixedly installed with a connecting block 10. The side of the connecting block 10 away from the Velcro 2 9 is provided with a square hole 13. The side of the connecting block 2 11 close to the connecting block 10 is fixedly installed with an insert block 12. The outer side of the connecting block 10 is provided with a through hole 1 4. Two sliding grooves 15 are symmetrically provided on the inner wall of the through hole 14. A receiving groove 16 is provided on the inner wall of the connecting block 10 and communicates with the through hole 14. A disc 17 is fixedly installed on the inner wall of the receiving groove 16. One end of four springs 18 is fixedly connected to the outer side of the disc 17. The other end of the four springs 18 is fixedly connected to a disc 2 19. An insertion rod 20 is slidably connected to the inner wall of the through hole 14. Two clamping blocks 21 are symmetrically fixedly installed on the outer edge of the insertion rod 20. A positioning disk 22 is fixedly installed on the end of the insertion rod 20 away from the clamping block 21.

[0031] See Figure 2 The inner wall of the trachea 2 is fixedly equipped with a sealing gasket 3, and the inner wall of the sealing gasket 3 is rotatably connected to a ball valve 4. A ball port 5 is opened through the inner wall of the ball valve 4, and the outer edge of the ball valve 4 is fixedly connected to a valve stem 7, so that the position of the ball port 5 can be adjusted by rotating the valve stem 7 to drive the ball valve 4 to rotate on the inner wall of the sealing gasket 3, so that the inner wall of the trachea 2 can be sealed when the airbag 1 is in the inflated state, and the sealing effect of the ball valve 4 on the inner wall of the trachea 2 can be guaranteed by the sealing gasket 3 to ensure that the gas will not leak easily.

[0032] See Figure 1 A high-grade concrete structure 23 and a low-grade concrete structure 24 are symmetrically fixedly installed on both sides of the airbag 1, so that it can provide an interception effect on high-grade and low-grade concrete.

[0033] See Figure 3 and Figure 4 The plug block 12 is inserted into the inner wall of the square hole 13. The inner wall of the plug block 12 is also provided with a through hole 14 and two slide grooves 15. The side of the connecting block 10 close to the square hole 13 is in contact with the side of the connecting block 2 11 close to the plug block 12, so that the plug block 12 can be inserted into the inner wall position of the square hole 13 to quickly realize the connection between the connecting block 10 and the connecting block 2 11, thereby facilitating the connection and combination of multiple airbags 1. It is installed in the middle position of the high-grade concrete structure 23 and the low-grade concrete structure 24 to provide an interception effect on the high and low-grade concrete at different positions.

[0034] See Figure 4The second disc 19 is slidably connected to the inner wall of the receiving groove 16. The outer diameter of the second disc 19 is adapted to the inner wall diameter of the receiving groove 16, so that the end of the insertion rod 20 close to the card block 21 squeezes the second disc 19 to move the card block 21 to the inner cavity position of the receiving groove 16, and the second disc 19 can abut the card block 21 when the card block 21 is completely moved to the inner cavity of the receiving groove 16 and is staggered with the positions of the two sliding grooves 15, thereby ensuring that the card block 21 will not easily fall off the inner wall of the receiving groove 16.

[0035] See Figure 4 The outer diameter of the insertion rod 20 is adapted to the inner wall diameter of the through hole 14, and the two blocking blocks 21 are slidably connected to the inner walls of the two slide grooves 15, so that after the insertion rod 20 is inserted into the inner wall position of the through hole 14, the insertion block 12 can be stably positioned at the inner wall position of the square hole 13, thereby ensuring that there will be no gap when plugging in, and no shaking will occur at will.

[0036] See Figure 4 The distance between the side of the positioning plate 22 close to the insertion rod 20 and the connecting block 10 is consistent with the thickness of the block 21. A handle is fixedly installed on the side of the positioning plate 22 away from the insertion rod 20, so that after the two blocks 21 abut against the inner wall of the accommodating groove 16, the side of the positioning plate 22 close to the insertion rod 20 will also fit tightly with the outer side of the connecting block 10, so that the insertion block 12 can be stably positioned on the inner wall of the square hole 13.

[0037] See Figure 2 The outer edge of the air pipe 2 is fixedly equipped with a fixed tube 6, and the valve stem 7 is rotatably connected to the inner wall of the fixed tube 6, so that the valve stem 7 can be positioned during rotation, thereby ensuring the stability of the valve stem 7 during rotation, and thus ensuring that it will not easily deviate or swing in position during rotation.

[0038] Working principle: When using the device, first, the air pump can be used to inflate the trachea 2, and then the airbag 1 can be inflated to an expanded state. Then, the valve stem 7 can be rotated to drive the ball valve 4 to rotate until the opening of the ball mouth 5 fits with the inner wall of the sealing gasket 3, thereby sealing the inner cavity of the trachea 2 to ensure that the gas in the inner cavity of the airbag 1 will not leak easily. By taking the connecting block 10, the Velcro 2 9 on the outer edge is bonded to the Velcro 1 8, and then the connection between the connecting block 10 and the airbag 1 can be achieved. By taking the connecting block 2 11, the plug 12 is inserted into the inner wall of the square hole 13, and then the insertion rod 20 is inserted into the inner wall of the through hole 14 and the two card blocks 21 are inserted into the inner walls of the two slide grooves 15, until the insertion rod 20 is close to the card block 21. One end of the disc 2 is squeezed to move the block 21 completely to the inner cavity position of the accommodating groove 16, and then the handle is turned to stagger the position of the block 21 with the two slide grooves 15, and then the elastic force of the spring 18 is used to abut the block 21, ensuring that the block 21 will not fall off easily on the inner wall of the accommodating groove 16, so that the insertion block 12 can be stably positioned on the inner wall of the square hole 13, realizing the connection between the connecting block 10 and the connecting block 2 11, and then the other air bags 1 can be bonded to the outer position of the connecting block 2 11, so as to facilitate the connection and combination of multiple air bags 1, and install them to the middle position of the high-grade concrete structure 23 and the low-grade concrete structure 24 to provide interception effect on high and low-grade concrete at different positions.
