Expansion release, reexpansion release can be carried out to the gases at high pressure in the first anechoic chamber by the second anechoic chamber.Disappear first
Under the cooperation of tone chamber and the second anechoic chamber, noise caused by blast can be made to reduce nearly half left and right, be effectively protected user's
Hearing.
2nd, external screw thread is designed with the connection ring in the utility model, the first anechoic chamber and second is disappeared using connection ring
Tone chamber's set connects, more convenient when dismounting nail pipe is safeguarded.
3rd, the secondary noise-reducing structure in the utility model can be achieved by connection ring and two silencer covers, both have knot
The advantages that structure is simple, cost is cheap, noise is enough greatly reduced in and can, is advantageous to scale manufacture.
4th, the first silencer cover in the utility model only has sound deadening, and stress is little；And the second silencer cover is except noise reduction
Effect is outer, is also connected with nail pipe and nailing device rear portion, stress is larger in use.Therefore, the thickness of the first silencer cover is less than
The structure of the thickness of second silencer cover, advantageously reduces cost and weight.The external diameter of the external diameter of first silencer cover, the second silencer cover
With the structure of the external diameter all same of connection ring, this three is set to connect together rear outer surface smoother, in use return spring
Motion is more smooth.
5th, the volume of the first anechoic chamber in the utility model is 15 cm3, the volume of the second anechoic chamber is 35cm3, not
Nailing device is carried out under larger change, the volume of anechoic chamber can be made to reach 50 cm3（The volume sum of Liang Ge anechoic chambers）, this
Be the equal of the volume of 3 times of existing anechoic chambers, significantly reduce using noise.
6th, the utility model sets 2-10 a diameter of 1-4mm biography stomata in connection ring, can make the first anechoic chamber
Interior gases at high pressure quickly expand to the second anechoic chamber, reach the purpose of fast and effective noise reduction.
