Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the attached drawings.

The utility model provides an idle call silencer convenient to dismouting as shown in fig. 1-4, including muffler main part 2, first ring flange 6, second ring flange 7, first ring flange 6 has seted up through-hole 8 on the surface, second ring flange 7 has seted up through-hole 8 on the surface, the quantity of through-hole 8 is established to a plurality ofly, bolt 4 and 5 fixedly connected with second ring flanges 7 of fixation nut are passed through to 6 sides of first ring flange, bolt 4 and 5 both of fixation nut match each other, bolt 4's length is longer than first ring flange 6 and 7 superimposed thicknesses of second ring flange slightly, bolt 4's diameter is less than through-hole 8's diameter slightly, be connected with air inlet 1 on the 7 inner walls of second ring flange.

2 one end of muffler main part is connected with air inlet 1, and the 2 other ends of muffler main part are connected with gas outlet 3, and the appearance of air inlet 1 and gas outlet 3 all sets up to tubaeform, and the size of a dimension of air inlet 1 and gas outlet 3 is unanimous, and air inlet 1 and gas outlet 3 are the symmetry setting.

The silencer body 2 comprises silencing holes 2001, a first silencer 2002, a second silencer 2003, a third silencer 2004 and a silencer cavity 2005, the interior of the silencer body 2 is hollow, the silencing holes 2001 are formed in the silencer body 2, the number of the silencing holes 2001 is set to be a plurality of, the silencing holes 2001 are filled with sound absorbing cotton, the first silencer 2002 is installed in the silencer cavity 2005 of the silencer body 2, the second silencer 2003 is installed on the outer side of the first silencer 2002, the third silencer 2004 is arranged on the outer side of the second silencer 2003, the first silencer 2002 and the third silencer 2004 are symmetrically arranged with respect to the second silencer 2003, and the silencer cavity 2005 is formed in the silencer body 2.
