[0008] Two limiting rings are symmetrically arranged at both ends of the steel pipe body. Two first clamping frames and two second clamping frames are symmetrically arranged between the two limiting rings. Multiple second reinforcing strips that contact the outer wall of the steel pipe body are provided between the two first clamping frames and between the two second clamping frames. The two ends of the first clamping frames are connected and fixed to the two ends of the second clamping frames, and the limiting rings can limit the first clamping frames and the second clamping frames.

[0009] Furthermore, an improvement of this utility model is that the first reinforcing strip has an arc-shaped structure.

[0010] Furthermore, an improvement of this utility model is that the second reinforcing strip is a cylindrical structure.

[0011] To make the limiting ring more securely installed, the improvement of this utility model is that the limiting ring is welded to the outer wall of the steel pipe body.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a tube for ultra-high pressure gas storage airbags, which has the following beneficial effects:

[0016] The reinforced ring and the first reinforcing strip provide a support structure for the reinforced ring on the inner wall. The multiple second reinforcing strips provide a protective structure for the steel pipe body on the outer wall, which can improve the rigidity and pressure resistance of the steel pipe body, thereby improving the service life and stability of the steel pipe body during use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 The ultra-high pressure gas storage safety airbag tube of this utility model includes a steel pipe body 1. The steel pipe body 1 is provided with a plurality of reinforcing rings 2 inside, and a plurality of first reinforcing strips 3 that contact the inner wall of the steel pipe body 1 are provided between the plurality of reinforcing rings 2.

[0026] Two limiting rings 4 are symmetrically arranged at both ends of the steel pipe body 1. Two first clamping frames 5 and two second clamping frames 12 are symmetrically arranged between the two limiting rings 4. Multiple second reinforcing strips 6 that contact the outer wall of the steel pipe body 1 are provided between the two first clamping frames 5 and between the two second clamping frames 12. The two ends of the first clamping frames 5 are connected and fixed to the two ends of the second clamping frames 12. The limiting rings 4 can limit the first clamping frames 5 and the second clamping frames 12.

[0027] In this structure, the reinforcing ring 2 and the first reinforcing strip 3 provide a support structure for the reinforcing ring 2 on the inner wall of the reinforcing ring 2. The multiple second reinforcing strips 6 provide a protective structure for the steel pipe body 1 on the outer wall of the steel pipe body 1, which can improve the rigidity and pressure bearing capacity of the steel pipe body 1, thereby improving the service life of the steel pipe body 1 and the stability of the steel pipe body 1 during use.

[0028] The limiting ring 4 can limit the first clamping frame 5 and the second clamping frame 12. The materials of the first clamping frame 5, the second reinforcing strip 6, the reinforcing ring 2 and the first reinforcing strip 3 can be the same as those of the steel pipe body 1, such as alloy steel or stainless steel.

[0029] In this embodiment, the first reinforcing strip 3 is an arc-shaped structure, and the second reinforcing strip 6 is a cylindrical structure.

[0030] In this embodiment, the limiting ring 4 is welded to the outer wall of the steel pipe body 1, which makes the limiting ring 4 more securely installed.

[0031] In this embodiment, the second clamping frame 12 has positioning grooves 9 at both ends, and a slot 10 is provided on the inner wall of the positioning groove 9. The first clamping frame 5 has positioning blocks 7 at both ends that are inserted into the positioning grooves 9. The positioning blocks 7 have cavities inside, and springs are provided inside the cavities. One end of the spring has a locking block 8 that cooperates with the slot 10. The second clamping frame 12 has screw holes 11 at both ends located at the top of the positioning grooves 9, and the screw holes 11 communicate with the positioning grooves 9. When it is necessary to align the first clamping frame 5 with the second clamping frame 12, the positioning blocks 7 are inserted into the positioning grooves 9. At this time, the springs can provide... The locking block 8 provides a spring force. Through the cooperation of the locking block 8 and the locking groove 10, the positioning block 7 can be fixed in the positioning groove 9, thereby making the first clamping frame 5 and the second clamping frame 12 more firmly connected and improving the stability of the second reinforcing strip 6 during use. The locking block 8 can be a trapezoidal structure. When it is necessary to disassemble the first clamping frame 5 and the second clamping frame 12, take the specified bolt and make the bolt pass through the screw hole 11. As the bolt is turned, the locking block 8 can compress the spring and push the locking block 8 out in the locking groove 10. At this time, the positioning block 7 can be pulled out in the positioning groove 9, which makes it easy to separate the first clamping frame 5 and the second clamping frame 12.
