Plate is bolted, and the one end of the fixed plate away from installing plate is provided with the 3rd mounting hole and passes through bolt and gasoline engine body
Connection.
Principle：The fixed plate one end covered after muffler body forms installing plate towards away from the bending of muffler body direction, is pacifying
Be provided with one or more the first mounting hole in loading board, the flange bending place on blast pipe be also provided with one or more second
Among mounting hole, the first mounting hole and the second mounting hole at least one at be multiple holes, so pass through the first mounting hole and second
The bolt between different holes between mounting hole tightly adjusts blast pipe into the position in cavity, can not only change silencer
Overall width, its soundproof effect can also be changed；The flange arrangement of the flange of blast pipe one end installs the rear side of muffler body
Mode is changed to side mounting means, increases installation operation space, also more convenient when conveniently installing and dismantling.
Compared to prior art, the present invention has the advantages that：Blast pipe can stretch into the diverse location of intracavitary, energy
The spectral performance of silencer is enough controlled, good soundproof effect can be obtained in the frequency range of needs；On gas exhaust tube flange
Increase a bending mount point, the rear side mounting means of former silencer is changed to side mounting means, thus in installation silencer
When operation it is simpler, be easily installed and dismantle.

Embodiment
The technical solution of the utility model is described in detail as follows with reference to drawings and Examples
As shown in figure 1, a kind of silencer, including：Muffler body, blast pipe 9 and erecting device, the muffler body bag
Include the protecgulum 1 to form noise elimination cavity and bonnet 5 and noise elimination cavity be divided into the dividing plate 4 of first chamber and second chamber, it is described every
There is passage on plate 4 and be provided with relative with the position of an air inlet 6 and sizable depression, the He of air inlet 6 of muffler body
Gas outlet 2 is separately positioned on the bonnet 5 and protecgulum 1 of muffler body, and forms one by air inlet 6, first chamber, second
Chamber and gas outlet 2 are sequentially communicated the exhaust passage to be formed, and the first hush tube provided with passage is connected with inside the protecgulum 1
31, the second hush tube 32 provided with passage is connected with the dividing plate 4, and the wherein caliber of downtake pipe 31 is less than second row
The caliber of tracheae 32, after protecgulum 1, bonnet 5 and dividing plate 4 assemble, that is, the first hush tube 31 is caused to stretch into the second hush tube
In 32, material is thus formed compact structure, and beneficial to good soundproof effect is realized, dividing plate 4, the first hush tube 31 and second disappear
Hole on sound pipe 32 can increase the resistance that sound is propagated in atmosphere, and the waste gas of engine enters noise elimination cavity by blast pipe 9
