[0025] As Figures 1-4 shown, sliding grooves 110 are opened on the inner walls at the left and right ends of the outer bottle body 104. Sliding bars 109 are fixedly connected to the outer walls at the left and right ends of the inner bottle body 105.

[0026] During implementation, by rotating the base 101 to separate it from the bottom of the outer bottle body 104, the arrangement of the sliding grooves 110 and the sliding bars 109 enables personnel to easily assemble the inner bottle body 105 and the outer bottle body 104 according to needs, so that the anti-rust coating on the outer surface of the inner bottle body 105 and the inner wall of the outer bottle body 104 can be repaired and supplemented, greatly improving the anti-rust performance. At the same time, the setting of the outer bottle body 104 further improves the protection during transportation. The overall structure is simple and stable, and it is convenient to use, with good practicality.

[0027] Embodiment 2:

[0028] As shown Figures 1-4 In the first embodiment, the present utility model provides an anti-rust steel cylinder technical solution: two sliding strips 109 are respectively located in two sliding grooves 110, and a support block 106 is provided at the bottom end of the inner cylinder 105.

[0035] In this technical solution, by rotating the top cover 102 to separate it from the top of the outer bottle body 104, gas storage and release of the inner bottle body 105 can be carried out. The sealing ring 107 and the sealing gasket 103 effectively ensure the sealing performance of the inner bottle body 105 inside the outer bottle body 104. By rotating the base 101 to separate it from the outer bottle body 104, the inner bottle body 105 can be taken out through the connection of the sliding bar 109 and the sliding groove 110, so that the inner wall of the outer bottle body 104 and the outer wall of the inner bottle body 105 can be coated with and repaired the anti-corrosion coating, ensuring that the gas is always stored in a stable anti-corrosion environment. When the base 101 is removed, by using the setting of the limiting groove 203 and the limiting ring 204, the outer protection plate 201 can be installed and disassembled. By adding an anti-corrosion coating to the outer protection plate 201, the overall anti-corrosion performance and the protection performance during transportation can be further improved.
