Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0033] Reference Figure 1-6The utility model is a metal hose for an ejection seat, comprising a bellows 1 and a first connecting pipe 3. Both ends of the bellows 1 are fixed with straight edge sections 2. The waveform of the bellows 1 is similar to an Ω shape. A connecting sleeve 4 is fixedly connected to the left side of the first connecting pipe 3. A liner ring 5 is arranged outside the straight edge section 2. The liner ring 5, the straight edge section 2 and the connecting sleeve 4 are welded by argon arc welding so that a weld seam exists on the outside. A first mounting sleeve 6 is fixedly connected to the right side of the first connecting pipe 3. The first mounting sleeve 6 is convenient for connecting with the second connecting pipe 9. Four limiting columns 7 are fixedly connected to the outside of the first mounting sleeve 6 to facilitate limiting the sealing ring 8. A sealing ring 8 is provided on the outside of the column 7, a second connecting tube 9 is provided on the right side of the first connecting tube 3, a second mounting sleeve 10 is connected to the fixed rod on the left side of the second connecting tube 9, and sealing sleeves 11 are provided on the outside of the upper and lower ends of the first mounting sleeve 6 and the second mounting sleeve 10, and the first mounting sleeve 6 and the second mounting sleeve 10 can be connected through the sealing sleeve 11. Connecting blocks 13 are fixedly connected on both sides of the two sealing sleeves 11 to achieve the effect of connection and fixing. The bottoms of the two upper connecting blocks 13 are fixedly connected to limiting blocks 14 to facilitate fixing the upper sealing sleeve 11, and disassembly components are provided on the tops of the two lower connecting blocks 13.

[0034] Reference Figure 4 The disassembly component includes a fixed plate 15, the bottoms of the two fixed plates 15 are fixedly connected to the connecting block 13, the top of the fixed plate 15 is provided with a slide groove 16, and two limit clamps 17 are slidably connected in the slide groove 16. Support plates 18 are fixedly connected on both sides of the fixed plate 15, and pull rods 19 are penetrated and slidably connected in the two support plates 18. The opposite ends of the two pull rods 19 are fixedly connected to the limit clamps 17. The disassembly component cooperates with the limit clamping block 14 to facilitate the rapid fixation of the two sealing sleeves 11, and facilitate the rapid disassembly of the first connecting pipe 3 and the second connecting pipe 9.

[0035] Reference Figure 3 , Figure 4 and Figure 6 The first connecting pipe 3 is arranged on the right side of the corrugated pipe 1, and the first connecting pipe 3 drives the connecting sleeve 4 to be inserted into the straight edge section 2. The sealing ring 8 is arranged between the first mounting sleeve 6 and the second mounting sleeve 10. A locking groove 12 is opened in the sealing sleeve 11. The inner wall of the locking groove 12 is slidably connected to the outside of the first mounting sleeve 6 and the second mounting sleeve 10. The locking groove 12 is trapezoidal. When squeezed, the first mounting sleeve 6 and the second mounting sleeve 10 can be connected more tightly, so that the connection effect is better. The connecting sleeve 4 is arranged in the straight edge section 2, and the two pull rods 19 are fixedly connected to the limit plate 20 at the opposite ends. The limit plate 20 is arranged on the outside of the support plate 18. The two pull rods 19 are both sleeved with springs 21 on the outside. The spring 21 is arranged between the support plate 18 and the limit clamp 17. The two limit clamps 17 can be driven to move relative to each other through the reset of the spring 21.

[0036] Working principle: when in use, when working, the bellows 1 has a straight edge section 2, the connecting sleeve 4 on the first connecting pipe 3 is inserted into the straight edge section 2, and then the liner ring 5 is pressed onto the straight edge section 2, and then the liner ring 5, the straight edge section 2, and the connecting sleeve 4 are welded by argon arc welding. The weld exists on the outside and is not in direct contact with the medium. The weld is also easy to handle. By using a bellows 1 with a smaller wall thickness, the flexibility and compression performance of the bellows 1 are increased, thereby reducing the rigidity and better adapting to the vibration and deformation inside the pipeline, thereby improving the compensation capacity of the bellows 1; the waveform is similar to the Ω shape, which is suitable for occasions with high pressure, small displacement, and small deflection. When the second connecting pipe 9 needs to be installed, the second installation sleeve 10 of the second connecting pipe 9 is aligned with the first installation sleeve 6 of the first connecting pipe 3, and then the two sealing sleeves 11 are put on the outside of the first installation sleeve 6 and the second installation sleeve 10, and squeezed to insert the limit blocks 14 on both sides of the upper sealing sleeve 11 When the two limit clamps 17 are pressed, the two limit clamps 17 slide to both sides in the slide groove 16, and the two limit clamps 17 press the springs 21 to both sides. After the limit clamp 14 enters the two limit clamps 17, the springs 21 reset, driving the two limit clamps 17 to move relative to each other again to limit the limit clamp 14, so that the first installation sleeve 6 and the second installation sleeve 10 can be fixed through the two sealing sleeves 11, and the locking groove 12 is trapezoidal, which can connect the first installation sleeve 6 and the second installation sleeve 10 more tightly when pressed, so that the connection effect is better. When disassembly is required, the limit plate 20 is pulled by hand to drive the pull rod 19 and the limit clamp 17 to move, release the restriction on the limit clamp 14, and facilitate the limit clamp 14 to be pulled out from the two limit clamps 17, and complete the disassembly of the sealing sleeve 11.
