[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a new explosion-proof metal hose, including a hose body 1, the left end of the hose body 1 is fixedly connected to a first connecting piece 11, the right end of the hose body 1 is fixedly connected to a second connecting piece 12, the surface of the first connecting piece 11 and the surface of the second connecting piece 12 are both fixedly connected to a flange 13, the surface of the hose body 1 includes:

[0026] The explosion-proof component 2 includes a protective layer 21, and a plurality of airbags 22 are provided on the surface of the protective layer 21. The airbags 22 are evenly distributed on the surface of the protective layer 21. The opposite sides of the plurality of airbags 22 are fixedly connected with a mounting layer 23. An air cavity 24 is provided on the surface of the mounting layer 23, and a plurality of ventilation holes 25 connected to the airbags 22 are provided on the inner wall of the mounting layer 23. The materials of the protective layer 21, the airbags 22 and the mounting layer 23 are all made of rubber.

[0027] The left end of the protective layer 21 and the left end of the installation layer 23 are both fixedly connected to the right side of the first connecting member 11 , and the right end of the protective layer 21 and the right end of the airbag 22 are both fixedly connected to the left side of the second connecting member 12 .

[0028] A protection spring 26 is sleeved on the surface of the mounting layer 23 . The left and right ends of the protection spring 26 are fixedly connected to the right side of the first connecting member 11 and the left side of the second connecting member 12 respectively.

[0029] A metal tube 27 is sleeved on the surface of the protection spring 26 , and the left and right ends of the metal tube 27 are fixedly connected to the right side of the first connecting member 11 and the left side of the second connecting member 12 respectively.

[0030] During use, after the hose body 1 explodes, the hose body 1 will generate an impact force after the explosion. At this time, the impact force generated by the hose body 1 reaches the protective layer 21. After the airbag 22 on the surface of the protective layer 21 is impacted, it is deformed. At this time, the gas in the airbag 22 enters the air cavity 24 in the mounting layer 23 through the vent 25. The gas in the air cavity 24 is squeezed and discharged through the vent pipe 28. During the process of the gas in the airbag 22 slowly being discharged, the impact force is buffered, thereby preventing the impact force after the explosion of the hose body 1 from being too large and affecting nearby equipment.

[0031] At the same time, under the action of the first connecting member 11 and the second connecting member 12, it is convenient to connect the two hose bodies 1, and under the action of the flange 13, it is convenient to fix the two hose bodies 1. Under the action of the protective spring 26, the bending degree of the hose body 1 is protected, and under the action of the metal tube 27, the surface of the hose body 1 is protected.

[0032] Example 2

[0033] Reference Figure 1-4 , which is the second embodiment of the present utility model, the right side of the upper side of the mounting layer 23 and the right side of the inner wall of the metal tube 27 are fixedly connected with a vent pipe 28, and an exhaust flow limiting component 29 is provided inside the vent pipe 28. The exhaust flow limiting component 29 includes a valve block 291, and a ball valve 292 is provided inside the valve block 291. A connecting rod 293 is fixedly connected to the upper side of the ball valve 292, and a limiting plate 294 is fixedly connected to the upper end of the connecting rod 293. A return spring 295 is fixedly connected to the lower side of the limiting plate 294 and the upper side of the valve block 291. The return spring 295 is sleeved on the surface of the ball valve 292 and the surface of the connecting rod 293.

[0034] The surface of the valve block 291 is fixedly connected to the inner wall of the vent pipe 28 .

[0035] During use, when the gas in the airbag 22 and the air cavity 24 is squeezed out, the gas at this time squeezes the ball valve 292 in the valve block 291 in the ventilation pipe 28. The squeezed ball valve 292 moves away from the valve block 291, and the return spring 295 is stretched. The ball valve 292 drives the connecting rod 293 and the limit plate 294 to move upward, so that the gas can be discharged outward through the valve block 291 and the ventilation pipe 28, and the valve block 291 and the ball valve 292 can slow down the flow rate of gas discharge, thereby slowing down the speed at which the airbag 22 deforms.

[0036] The remaining structures are the same as those of Example 1.
