Abstract
The utility model discloses an upright exhaust silencer, comprising a silencing shell body fastened by two metal shells and a filter element arranged in the inner chamber of the shell body. A side of the silencing shell body is provided with protection plates with intervals along the axial direction. The protection plates are connected through connecting pins and connecting holes arranged on a longitudinal turning side of the silencing shell body. The upright exhaust silencer is characterized in that the peripheral surfaces of the connecting holes are integral structures which are arranged by an extruding method. The utility model has the advantages that the longitudinal turning side of the silencing shell body is connected with the integral structures of the inner peripheral surfaces of the connecting holes. Therefore, the upright exhaust silencer avoids the phenomenon of the air leakage at the combining slits of the connecting holes. At the same time, the strength of the silencing shell body is also raised, and the service life is longer.
Description
Technical field:
The utility model relates to exhaust muffler for internal combustion engine, particularly relates to a kind of vertical muffler.
Background technique:
Use at present the vertical muffler on internal-combustion engine, after its muffler shell mostly is and is fastened by two metallic cases, with two metallic cases longitudinally flange be welded.For heat insulation, be arranged at intervals with protection apron vertically in muffler shell one side, protection apron is connected with attachment hole on being opened in the vertical flange of muffler shell by connecting pin, and the existing deficiency of vertical muffler of this structure is to be opened in attachment hole inner peripheral surface on the vertical flange of muffler shell to exist and leak gas in conjunction with the slit.This has not only influenced erasure effect, and has reduced the working life of muffler shell.
The model utility content:
The purpose of the utility model is to provide a kind of vertical muffler at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model is achieved in that
Vertical muffler described in the utility model, comprise that two metallic cases fasten the filter core in the muffler shell that forms and the chamber that sets within it, be arranged at intervals with protection apron vertically in muffler shell one side, described protection apron is connected with attachment hole on being opened in the vertical flange of muffler shell by connecting pin, it is characterized in that described attachment hole inner peripheral surface is an overall structure.
Advantage of the present utility model is the attachment hole inner peripheral surface on the vertical flange of muffler shell is arranged to overall structure by the impact extrusion molding mode, thereby has avoided locating gas leak phenomenon from attachment hole in conjunction with the slit; Also improve simultaneously the intensity of muffler shell, prolonged working life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure, vertical muffler described in the utility model, comprise that two metallic cases fasten the filter core in the muffler shell 1 that forms and the chamber that sets within it, be arranged at intervals with protection apron 2 vertically in muffler shell 1 one sides, described protection apron 2 is connected with attachment hole 5 on being opened in muffler shell 1 vertical flange 4 by connecting pin 3, described attachment hole 5 adopts the manufacturing of impact extrusion molding mode, and making inner circumferential surface is overall structure.
