[0015] 1. This inflatable tubular rubber strip features a hollow, inflatable bottom fixing strip, allowing for adjustable inflation to control its hardness and sealing performance. An inflation / deflation nozzle at the bottom of the fixing strip facilitates inflation and deflation. Two cylindrical rubber sealing strips, integrally formed with the bottom fixing strip, on either side of the top of the fixing strip, enhance the overall stability and sealing of the tubular rubber strip. The hollow interiors of these two sealing strips, connected to the bottom fixing strip, facilitate gas flow and inflation / deflation. A soft metal braided layer enhances the sealing strip's strength and toughness, preventing damage during use. An outer rubber layer on the soft metal braided layer provides excellent sealing and wear resistance. An anti-corrosion inner layer within the soft metal braided layer improves the sealing strip's corrosion resistance and extends its service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms "center", "vertical", "horizontal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0028] An inflatable tubular rubber strip, such as Figures 1-3As shown, the device includes a hollow, inflatable bottom fixing strip 10 and rubber sealing strips 20 located on both sides of the top of the bottom fixing strip 10. An inflation / deflation nozzle 30 for inflating / deflating the interior is installed at the bottom of the bottom fixing strip 10. The two sets of rubber sealing strips 20 are cylindrical tubes, and the bottom fixing strip 10 and the two sets of rubber sealing strips 20 are integrally formed. The two sets of rubber sealing strips 20 are hollow and connected to the interior of the bottom fixing strip 10. Each set of rubber sealing strips 20 includes a soft metal braided layer 21. A rubber outer layer 22 is provided on the outer wall of the soft metal braided layer 21, and an anti-corrosion inner layer 23 is provided inside the soft metal braided layer 21. By using the hollow, inflatable bottom fixing strip 10, the tubular rubber strip can be inflated as needed during use to adjust its hardness and sealing performance. The bottom fixing strip 10... The inflation / deflation nozzle 30 installed on the top facilitates inflation / deflation of the tubular rubber strip. The rubber sealing strips 20 located on both sides of the top of the bottom fixing strip 10 are cylindrical and integrally formed with the bottom fixing strip 10, making the entire tubular rubber strip structure more stable and providing better sealing. Simultaneously, the two sets of rubber sealing strips 20 are hollow and connected to the interior of the bottom fixing strip 10, facilitating gas flow and inflation / deflation. The soft metal braided layer 21 included in the rubber sealing strip 20 enhances its strength and toughness, making it less prone to damage during use. The rubber outer layer 22 on the outer wall of the soft metal braided layer 21 provides good sealing performance and wear resistance. The anti-corrosion inner layer 23 inside the soft metal braided layer 21 improves the corrosion resistance of the rubber sealing strip 20 and extends its service life.
[0029] Furthermore, the bottom fixing strip 10 includes an inner support layer 11 and a sealing outer layer 12 on the surface. By providing the inner support layer 11, the structural strength of the bottom fixing strip 10 is enhanced, enabling it to withstand greater pressure without easily deforming, thereby ensuring the stability and durability of the overall product. The sealing outer layer 12 effectively prevents gas from leaking from the surface of the bottom fixing strip 10, ensuring the sealing and durability after inflation.
[0030] Specifically, the thickness of the soft metal braided layer 21 is 1-3mm, the thickness of the rubber outer layer 22 is 1-2mm, and the thickness of the anti-corrosion inner layer 23 is 0.5-1.5mm, which improves stability.
[0031] It is worth noting that the bottom of the bottom fixing strip 10 is also provided with a wear-resistant thickened base 13, which improves the wear resistance of the bottom of the bottom fixing strip 10, prevents damage caused by long-term use or friction, and further extends the overall service life of the product.
[0032] The bottom of the air filling / draining nozzle 30 is coaxially connected to a hollow external threaded connector 31. The air filling / draining nozzle 30 is connected to a sealing cap 40 through the external threaded connector 31 to prevent impurities from entering and causing blockage, while also improving the sealing effect.
[0033] In addition, the outer wall of the sealing cap 40 is provided with a non-slip outer sleeve 41 with a thickness of 0.5-1mm, which makes the sealing cap 40 easier to grip when disassembling or installing, and avoids accidental drop or damage due to slipping.
[0034] The working principle of this inflatable tubular rubber strip:
[0035] First, check the overall condition of the tubular rubber strip to ensure that the bottom fixing strip 10, rubber sealing strip 20 and inflation / deflation nozzle 30 are not obviously damaged.
[0036] Next, air is injected into the bottom fixing strip 10 through the inflation / deflation nozzle 30; since the two sets of rubber sealing strips 20 are hollow inside and connected to the inside of the bottom fixing strip 10, the gas will also enter the rubber sealing strips 20.
[0037] As gas is introduced, the bottom fixing strip 10 gradually expands and plays a role in fixing and supporting; at the same time, the rubber sealing strip 20 also expands under the action of gas, its soft metal braided layer 21 provides strength and toughness, the rubber outer layer 22 is tightly attached to the sealing surface to achieve the sealing function, and the anti-corrosion inner layer 23 protects the internal structure from corrosion.
[0038] After use, the air can be released again through the inflation / deflation nozzle 30 for easy storage and future use.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
