Description of the drawings
Fig. 1 is the front view of silencer for electric drill.
Fig. 2 is the half section structure diagram of silencer for electric drill.
Specific implementation mode
The utility model is further described in the following with reference to the drawings and specific embodiments.
Fig. 1 is the front view of silencer for electric drill.
Fig. 2 is the half section structure diagram of silencer for electric drill.
As depicted in figs. 1 and 2, silencer for electric drill, including：Transparent housing 10, silencing cotton 20, mixed packing 30,12
Hush pipe 40 and sucker 50.
Transparent housing 10 is semicircle, is made of organic glass, not only light, drop resistant is also convenient for observing internal shape
State.
The front and rear sides of transparent housing 10 have perforative electric drilling 11,12.The drill bit Z of electric drill from two electric drillings 11,
After 12 pass through, to operation made above.Electric drilling 11 is aperture, i.e., the variable aperture being mutually stacked using multi-disc metal blade
Aperture.A circular aperture is enclosed if adding by dry plate metal film stack.As long as rotating vane, pore size can be changed, pasted
Bench drill head, cotton-padded covering makes muffler is not worn at work to nor affect on electric drill work in the outer cover of polygon.Electricity
Drilling 12 can also use iris diaphragm structure.
There is Electric drill support 60 on the inner wall of the rear side of transparent housing 10.When electric drill operation, drill bit Z can be rested on electric drill
On holder 60, play a supporting role.
Silencing cotton 20 is arranged on the inner wall of transparent housing 10.Hush pipe 40 is distributed in the cavity of transparent housing 10.By
It is semicircle in transparent housing 10, muffler is not plane setting, is arranged for layer.Mixing filling is also filled up between muffler 40
Object 30 absorbs the noise for not entering hush pipe 40.Mixed packing 30 is that filter paper, cork and sand paper are constituted.
Impedance composite muffler or microperforated panel silencer may be used in hush pipe 40.This can certainly be used simultaneously
Two kinds of silencers are staggered in transparent housing 10.Impedance composite muffler is resistive structures and resistance structure according to certain
Mode combine, just constitute impedance composite muffler, using deadener or the sound absorption of sound absorption structure, make edge
The noise of pipe transmmision is decayed with distance, to reach noise elimination purpose.Impedance composite muffler takes into account resistant noise-reducing device pair
The good noise elimination effect of high-frequency noise and resistant noise-reducing device are to the good noise elimination effect of Low Medium Frequency noise.Microperforated panel is eliminated the noise
Device is the silencer of lining dress microperforated panel structure.It can eliminate pneumatic noise in wider frequency range, and have high temperature resistant, resistance to
Greasy dirt, corrosion resistant performance nor affect on work even if carrying large quantity of moisture in the gas flow.Since penetration hole diameter is small, plate face light
It is sliding, therefore silencer resistance damage is smaller than general dissipative muffler.
The rear side in transparent casing 10 is arranged in sucker 50, can be adsorbed on working face.When according to electric drill operation, it can adsorb
At an arbitrary position；It is also convenient for removing after fulfiling assignment, it can this more Reusability.
The operation principle of silencer for electric drill：
Sucker 50 is adsorbed on working face, the drill bit Z of electric drill rests on electric drill after the electric drilling 11 of transparent housing 10
On holder 60, then it is pierced by from electric drilling 12.When electric drill operation on working face, the noise of generation by multiple hush pipes 40 and
Silencing cotton 20 and mixed packing absorb, and efficiently reduce noise, prevent the generation of noise pollution.
