Fig. 1 is the structural schematic diagram of fixed noise-decreasing device.
Fig. 2 is the structure size figure of upper holding ring, lower holding ring.
Fig. 3 is assembling schematic diagram when fixed noise-decreasing device fixes gas cylinder.
Reference numeral in figure：Lower cushion 1, studs 2, upper cushion 3, nut 4, gasket 5, upper holding ring 6, lower folder
Held in ring 7, supporting rack 8, bolt hole 9.
Specific implementation mode
Present invention is further described in detail below in conjunction with the accompanying drawings.Following embodiment is practical implementation, is only used for
Clearly illustrate technical scheme of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, it includes for holding to wind the fixation noise-decreasing device of composite cylinder acoustic emission detection entirely for carbon fiber
Weight and fixed supporting rack 8, and two groups of hold assemblies being fixedly attached to supporting rack 8 and be vertically arranged in parallel；Every group of clamping
Component is made of the upper holding ring 6 and lower holding ring 7 of polyamide material, and the two has the arc opening being oppositely arranged, arc
Spatial position between opening is as the holding tank for placing gas cylinder；It is set respectively in the both side ends of upper holding ring 6 and lower holding ring 7
