Abstract
The utility model relates to the technical field of automotive mufflers, in particular to a heat isolation plate structure of an automotive muffler. The heat isolation plate structure comprises an outer muffler shell and a heat isolation plate, wherein the muffler shell and the heat isolation plate have cambered surfaces; the heat isolation plate covers the muffler shell; holes are formed in four corners of the heat isolation plate; nuts are respectively fixed at positions of the muffler shell, which are matched with the holes; the heat isolation plate is fixed on the muffler shell through bolts; and pads are arranged between the nuts and the walls of the holes in the heat isolation plate. By the heat isolation plate structure of the automotive muffler, the holes in the heat isolation plate are used as fixing holes; the nuts are fixed on the muffler shell according to the positions of the holes, and the heat isolation plate is fixed on the muffler through the bolts; a distance between the heat isolation plate and the muffler is adjusted through the pads; the structure of the heat isolation plate is simplified; the whole structure is easy to assemble and arrange; and the cost is effectively reduced.
Description
Technical field
The utility model relates to the automotive muffler technical field, is specifically related to a kind of baffle of vehicle silencer structure.
Background technique
Silencing apparatus in the course of the work, the heat that distributes is very big, adopts in the industry thermal baffle to carry out heat insulation processing usually.Existing thermal baffle is arranged near the body platform the silencing apparatus or near the component assembly; This layout since at muffler shell body and thermal baffle not at same place; Thermal baffle needs enough length just can reach the effect that makes silencing apparatus heat insulation; Have the thermal baffle complex structure, arrange that difficulty is big, materials are many, the defective that cost of production is high.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned defective, provide a kind of simple in structure, arrange easily, baffle of vehicle silencer structure that cost is low.
To achieve these goals; The baffle of vehicle silencer structure of the utility model design; Comprise muffler shell body and thermal baffle, said muffler shell body and thermal baffle are arc shaped surface, and said thermal baffle covers on the muffler shell body; Four angle ends of said thermal baffle are provided with perforate; The position that said muffler shell body matches with perforate is fixed with nut respectively, and said thermal baffle is equipped with pad through being bolted on the muffler shell body between the hole wall of said nut and thermal baffle perforate.
In technique scheme, two perforates in the said thermal baffle upper left corner and the upper right corner are circular port, and two perforates in the said thermal baffle lower left corner and the lower right corner are slotted eye.
The utility model is provided with perforate as fixed hole on thermal baffle; On the muffler shell body according to the fixed-site nut of perforate; Through bolt thermal baffle is fixed on the silencing apparatus, and passes through the distance of pad adjustment thermal baffle and silencing apparatus, simplified the structural type of thermal baffle; Total is easy to install and arrange, effectively reduces cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the local sectional structure schematic representation that amplifies in A place among Fig. 1;
Among the figure: 1, muffler shell body; 2, thermal baffle; 3, nut; 4, bolt; 5, pad.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:
Baffle of vehicle silencer structure as depicted in figs. 1 and 2; Comprise muffler shell body 1 and thermal baffle 2, muffler shell body 1 is arc shaped surface with thermal baffle 2, and thermal baffle 2 covers on the muffler shell body 1; Four angle ends of thermal baffle 2 are provided with perforate; The position that muffler shell body 1 matches with perforate is welded with nut 3 respectively, and thermal baffle 2 is fixed on the muffler shell body 1 through bolt 4, between the hole wall of nut 3 and thermal baffle 2 perforates pad 5 is installed.
The utility model is according to the arcuate structure of thermal baffle; Two perforates in thermal baffle 2 upper left corners and the upper right corner are set to circular port; Two perforates in thermal baffle 2 lower left corners and the lower right corner are set to slotted eye, have strengthened thermal baffle 2 and have been fixed on the intensity on the muffler shell body 1.
The utility model is through the distance of pad 5 adjustment thermal baffles 2 with suppressor case 1; And thermal baffle 2 is fixed on the suppressor case 1 through bolt 4; Avoided being fixed on the body platform thermal baffle 2 or on other component assembly and the structure complexity that causes; Simplify the structural type and layout difficulty of thermal baffle 2, effectively reduced cost.
The content of not doing in this specification to describe in detail belongs to related domain professional and technical personnel's known prior art.
