[0027] In order to better understand the purpose, structure and function of the utility model, the novel micro-expansion nano-sealing device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a novel micro-expansion nano-sealing device of the utility model comprises a connecting column 2, an external thread is provided on the surface of the connecting column 2, an internal thread ring 3 is installed on the surface of the connecting column 2, a magnet ring 7 is bonded to the top of the internal thread ring 3, a shaft rod 8 is welded on the top of the internal thread ring 3, a baffle 9 is welded on the other end of the shaft rod 8, and a baffle ring 5 is sleeved on the surface of the shaft rod 8. By installing the baffle ring 5, the baffle ring 5 is rotated with the shaft rod 8 as the center until the baffle ring 5 and the shaft rod 8 reach the longest diameter. At this time, the baffle ring 5 can be used to limit the novel micro-expansion nano-sealing device inside the hole and ensure that it will not fall into the hole. It does not need to be held, and it is very convenient to use. A cavity 6 is provided inside the baffle ring 5, and the magnet ring 7 is located inside the cavity 6. The baffle ring 5 is made of metal iron. Under the premise that the baffle ring 5 is made of metal iron, when the magnet ring 7 is located in the cavity 6 inside the baffle ring 5, the magnetic attraction effect can be used to fix the baffle ring 5 on the internal thread ring 3, which is very convenient to use.

[0029] The first fixing ring 10 and the second fixing ring 11 are sleeved on the surface of the connecting column 2, the first fixing block 12 is welded on the top of the first fixing ring 10, the second fixing block 13 is welded on the top of the second fixing ring 11, the external threaded rod 14 is welded on the side of the second fixing block 13, the external threaded rod 14 passes through the first fixing block 12, and the nut 15 is installed on the surface of the external threaded rod 14, and the nut 15 is located on the side of the first fixing block 12. The bottom of the first fixing ring 10 and the second fixing ring 11 are both welded with an external threaded ring 16, and the surface of the external threaded ring 16 is sleeved with a protective sleeve 18. A nano airbag bag 1 is installed at one end of the connecting column 2, and the nano airbag bag 1 is located inside the protective sleeve 18. By installing the protective sleeve 18, during the operation of the new micro-expansion nano-sealing device, the protective sleeve 18 can be used to protect the nano airbag bag 1 so that it will not be hit, and the protective performance is strong when used.

[0030] A fixing rod 20 is welded on the top of the retaining ring 5, and a ball head 19 is welded on the other end of the fixing rod 20. The retaining ring 5 is in a ring-shaped distribution form. By installing the fixing rod 20, when the retaining ring 5 needs to be rotated, the fixing rod 20 can be used as a force point and the fixing rod 20 can be directly moved by hand, which is very convenient to use.

[0031] An anti-sliding block 4 is welded on the surface of the internal thread ring 3, and the anti-sliding block 4 is distributed in a ring shape. By installing the anti-sliding block 4, when the internal thread ring 3 is rotated, the friction between the internal thread ring 3 and the palm can be increased through the anti-sliding block 4, so that the hand will not slip when the internal thread ring 3 is rotated, and the stability is strong during use.

[0032] A limiting ring 17 is welded on the surface of the connecting column 2, and the limiting ring 17 is symmetrically distributed. Both ends of the first fixing ring 10 and the second fixing ring 11 are fitted with the limiting ring 17. By installing the limiting ring 17, the limiting ring 17 can provide a limiting effect for the first fixing ring 10 and the second fixing ring 11, so that after the first fixing ring 10 and the second fixing ring 11 are installed on the connecting column 2, they will not move up and down, and have strong stability when used.

[0033] The first fixing blocks 12 are symmetrically distributed, and the externally threaded rods 14 are symmetrically distributed. The externally threaded rods 14 are used to install the first fixing ring 10 and the second fixing ring 11. At this time, after the externally threaded rods 14 are used to fix the first fixing ring 10 and the second fixing ring 11 to each other, a stable installation effect can be provided, thereby improving stability during use.

[0034] The working principle of the novel micro-expansion nano-pore sealing device is as follows: when using the novel micro-expansion nano-pore sealing device, the internal thread ring 3 should be installed through the external thread on the surface of the connecting column 2, and then the novel micro-expansion nano-pore sealing device can be placed inside the hole that needs to be sealed. Before the novel micro-expansion nano-pore sealing device is embedded in the hole that needs to be sealed, the retaining ring 5 can be rotated with the shaft 8 as the center until the retaining ring 5 and the shaft 8 reach the longest diameter. At this time, the retaining ring 5 can be used to limit the novel micro-expansion nano-pore sealing device inside the hole and ensure that it will not fall into the hole. It does not need to be held by hand, and it is very convenient to use. After that, the micro-expansion nano-pore sealing device can be used normally to perform the hole sealing operation. When the retaining ring 5 is not needed, When the retaining ring 5 is rotated back to its original position with the shaft 8 as the center, until the magnet ring 7 is located in the cavity 6 inside the retaining ring 5, the retaining ring 5 can be fixed on the internal threaded ring 3 by utilizing the magnetic attraction effect. When a large number of micro-expansion nano-sealing devices need to be transported, the first fixing ring 10 and the second fixing ring 11 can be embedded between the limiting ring 17, and then the external threaded rod 14 is passed through the first fixing block 12 and fixed with the nut 15. Finally, the protective sleeve 18 is sleeved on the nano airbag bag 1, and the protective sleeve 18 is rotated to be installed on the external threaded ring 16. At this time, during the operation of the novel micro-expansion nano-sealing device, the protective sleeve 18 can be used to protect the nano airbag bag 1 so that it will not be hit, and the protective performance is strong during use.
