Abstract
A packaging shell for a hot end of an exhaust system comprises a straight cylinder part, a first flared part and a second flared part, wherein the first flared part is connected with the straight cylinder part and is positioned at one end of the straight cylinder part, the second flared part is connected with the straight cylinder part and is positioned at the other end of the straight cylinder part, the straight cylinder part is further provided with a plurality of reinforcing ribs distributed along the circumferential direction, and each reinforcing rib extends along the axial direction parallel to the straight cylinder part. Compared with the prior art, the utility model discloses a set up along a plurality of strengthening ribs that circumference distributes, each strengthening rib along being on a parallel with the axis direction of straight section of thick bamboo portion extends to improve the intensity of casing, increased the ability of resistance to deformation.
Description
Technical Field
The utility model relates to a packaging shell for exhaust system hot junction belongs to engine exhaust aftertreatment technical field.
Background
The hot end of the exhaust system, which typically includes a housing and a carrier encapsulated therein, is susceptible to deformation and failure from the high temperature exhaust gases due to the proximity of the hot end of the exhaust system to the engine.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stronger, the encapsulation casing that is used for exhaust system hot junction of anti deformability.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a packaging shell for a hot end of an exhaust system comprises a straight cylinder part, a first flared part and a second flared part, wherein the first flared part is connected with the straight cylinder part and is positioned at one end of the straight cylinder part, the second flared part is connected with the straight cylinder part and is positioned at the other end of the straight cylinder part, the straight cylinder part is further provided with a plurality of reinforcing ribs distributed along the circumferential direction, and each reinforcing rib extends along the axial direction parallel to the straight cylinder part.
As the utility model discloses further modified technical scheme, each strengthening rib is followed the radial evagination of straight section of thick bamboo portion.
As a further improved technical scheme of the utility model, each strengthening rib all is rectangular form.
As a further improved technical solution of the present invention, each of the reinforcing ribs is located in the axial direction of the straight cylinder portion between the first flared portion and the second flared portion.
Compared with the prior art, the utility model discloses a set up along a plurality of strengthening ribs that circumference distributes, each strengthening rib along being on a parallel with the axis direction of straight section of thick bamboo portion extends to improve the intensity of casing, increased the ability of resistance to deformation.
Drawings
Fig. 1 is a schematic perspective view of a package housing for a hot end of an exhaust system according to the present invention.
Detailed Description
Referring to fig. 1, the present invention discloses a packaging casing 100 for a hot end of an exhaust system, which includes a straight cylinder portion 1, a first flared portion 2 connected to the straight cylinder portion 1 and located at one end of the straight cylinder portion 1, and a second flared portion 3 connected to the straight cylinder portion 1 and located at the other end of the straight cylinder portion 1, wherein the straight cylinder portion 1 is further provided with a plurality of reinforcing ribs 11 distributed along a circumferential direction, and each reinforcing rib 11 extends along an axial direction a parallel to the straight cylinder portion 1.
Specifically, each of the reinforcing ribs 11 projects outward in the radial direction of the straight cylinder portion 1. Each rib 11 is elongate for ease of manufacture. Each of the ribs 11 is located between the first flared portion 2 and the second flared portion 3 in the axial direction a of the straight tube portion 1 so as to avoid an influence on the first flared portion 2 and the second flared portion 3.
Compared with the prior art, the utility model discloses a set up along a plurality of strengthening ribs 11 that circumference distributes, each strengthening rib 11 along being on a parallel with the axis direction A of straight section of thick bamboo portion 1 extends to improve casing 100's intensity, increased the ability of resistance to deformation, solved its axial stiffness in the lower problem of hot state.
The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical personnel in the technical field, and although the present specification has described the present invention in detail with reference to the above embodiments, the skilled personnel in the art should understand that the technical personnel in the technical field can still modify or substitute the present invention, and all the technical solutions and modifications thereof that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
