DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments;Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] Embodiment one

[0033] As Figures 1-4As shown, a gas cylinder includes a cylinder body 1, which also includes a nozzle 11, a shoulder 12, a body 13, a bottom 14, and a sealing cap 2. The sealing cap 2 is threadedly connected to the inner wall of the nozzle 11. An elastic liner 5 is fixed to the inner wall of the body 13. The elastic liner 5 is arranged circumferentially along the inner wall of the body 13. A buffer member 4 is provided inside the bottom 14. At least a partial buffer space 3 is provided between the buffer member 4 and the bottom 14.

[0034] The sealing cap 2 is threaded to the inner wall of the bottle mouth 11. An elastic liner 5 is fixed to the inner wall of the bottle body 13. The elastic liner 5 can be made of rubber and has flexibility and elasticity. The elastic liner 5 is arranged circumferentially along the inner wall of the bottle body 13. A buffer member 4 is provided inside the bottle bottom 14. At least a partial buffer space 3 is provided between the buffer member 4 and the bottle bottom 14. When the bottle body 1 is accidentally dropped during transportation or loading and unloading, it is subjected to impact at the moment it hits the ground. In traditional gas cylinders, the impact force directly acts on the gas inside, increasing the internal pressure and causing the cylinder body 1 to explode. However, this application provides an elastic liner 5 on the inner wall of the cylinder body 1. When the internal pressure increases, the pressure generated by the internal pressure acts on the elastic liner 5, preventing it from directly acting on the cylinder body 13. Correspondingly, when the internal pressure increases, the internal pressure can also act on the buffer member 4. The internal pressure can be absorbed by the buffer member 4, thereby improving the gas cylinder's resistance to high pressure and thus improving the safety of the gas cylinder.

[0035] Example 2

[0036] like Figures 1-4 As shown, the buffer component 4 includes a spring 42 and a buffer pad 41. The buffer pad 41 is disposed on the top of the spring 42. One end of the spring 42 is fixed to the inner wall of the bottle bottom 14, and the other end of the spring 42 is fixedly connected to the buffer pad 41. Several springs 42 are provided and are distributed in a ring array around the circumference of the bottle bottom 14. The buffer pad 41 is concave from the side to the middle. The concave arc of the buffer pad 41 is the same as the concave arc of the inner wall of the bottle bottom 14, which improves the gas cylinder's resistance to high pressure.

[0037] The sealing cap 2 includes a threaded plate 21. A first sealing plug 22 is fixed to the bottom of the threaded plate 21, and a second sealing plug 23 is fixed to the bottom of the first sealing plug 22. The first sealing plug 22 is conical, and the second sealing plug 23 is cylindrical. The height of the second sealing plug 23 is greater than the height of the first sealing plug 22, which improves the sealing performance of the gas cylinder. A threaded groove 110 is provided around the inner wall of the top of the nozzle 11 to facilitate the threaded sealing connection between the sealing cap 2 and the nozzle 11. The cylinder body 1 is integrally formed from the nozzle 11, the shoulder 12, the body 13, and the bottom 14 to ensure the strength of the cylinder body 1. A hexagonal groove 210 is provided at the center of the top of the threaded plate 21 to facilitate the disassembly and reassembly of the sealing cap 2 using a hexagonal wrench.

[0038] Example 3

[0039] like Figure 1 As shown, there is an inclination angle α between the bottle shoulder 12 and the bottle body 13. The inclination angle α ranges from 30° to 45°. Compared with the traditional flat shoulder, this design makes the bottle body 1 more rounded and full, and the overall body thick and sturdy. In addition, when the bottle body 1 needs to be inflated or deflated, the sealing cap 2 is connected to an air valve. The inflating or deflation of the bottle body 1 is achieved by opening and closing the air valve. This technology is existing technology.
