As shown in fig. 1 and 2, the utility model discloses an automobile purification silencer, including

silencer barrel

1, 1 inside intake pipe 2 and the outlet duct 3 that is located of silencer barrel is equipped with catalyst converter carrier 5 between, silencer barrel 1's bottom surface is just being equipped with bar mouth 11 to 5 departments of catalyst converter carrier, bar mouth 11's outside is equipped with the apron 9 that covers the bar mouth, apron 9 installs more than one limiting plate 4 on the surface, the limiting plate 4 upper end all passes bar mouth 11 and extends to 1 inside of silencer barrel, limiting plate 4 sets up respectively in catalyst converter carrier 5's both sides, all be equipped with the spacing groove perpendicularly on limiting plate 4's the opposite face, catalyst converter carrier 5's both sides all insert in the spacing groove, silencer barrel 1's outside is equipped with and compresses tightly the arc 6 on the silencer barrel with the apron.

In this embodiment, outwards protrusion forms an arc 13 on the top surface of silencer barrel 1, is equipped with the spout of arc structure on the outer wall of arc 13, and the medial surface of arc 6 offsets with the outer wall of arc and the outer wall of apron, and slider 8 is all installed to spout department just to the medial surface of arc 6, and slider 8 one end slidable mounting is in the spout, and spring 7 is installed to slider 8's one end, and the spring 7 other end is installed on the internal face of spout.

In this embodiment, more than one rubber layer 12 is embedded in the surface of the cover plate 9, and the inner side surfaces of the rubber layers 12 are all abutted against the outer wall surface of the muffler cylinder 1, so that the sealing performance between the cover plate and the muffler cylinder is improved.

In this embodiment, the top surface of the catalyst carrier 5 abuts against the top surface inside the muffler cylinder 1, and the outer side surface of the limiting plate 4 abuts against the partition plate inside the muffler cylinder 1, so as to separate the air inlet pipe from the air outlet pipe.

In this embodiment, the cross-section of spout and slider 8 is the setting of dovetail structure, and the phase-match has avoided the slider to break away from in the spout between spout and the slider 8.

Because the catalyst carrier sets up between intake pipe and outlet duct, and separates between intake pipe and the outlet duct to the intake pipe combustion gas must pass through the catalyst carrier, effectual with gas purification.

Wherein, because the apron is fixed through the arc board pressure fastening, consequently when dismantling, as long as anticlockwise rotation arc, remove the back from the apron at the arc, can direct pull-down apron to take out limiting plate and catalyst converter carrier along the bar mouth, can be quick change it or wash, accomplish the back, the rethread catalyst converter carrier inserts, and release the arc, the arc can rethread removal to the apron lower extreme of spring through the bounce-back of arc, will lap rethread pushing down.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention.
