Abstract

The utility model relates to a check ring of a three-way catalyst. The check ring of the three-way catalyst is arranged in the three-way catalyst, is of an integrated structure and comprises a check ring body, check ring base parts symmetrically arranged at the two ends of the check ring body and check ring protruding parts perpendicular to the check ring base parts. The check ring of the integrated structure resolves the problem of displacement of a honeycomb carrier, thereby effectively prolonging the service life of the three-way catalyst and improving the conversion rate of the three-way catalyst.

Description

The stop ring of ternary catalyzing unit

Technical field

The utility model relates to auto parts and components field, particularly a kind of stop ring of ternary catalyzing unit.

Background technique

The stop ring of ternary catalyzing unit is arranged in ternary catalyzing unit, is one of key components and parts of ternary catalyzing unit, and referring to Fig. 1, between two honeycomb substrates of ternary catalyzing unit of the prior art, being provided with 1,2, two stop rings of two stop rings is separately independently.

Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:

Independently two stop rings, in the situation that repeatedly shaking, easily occur becoming flexible separately, cause two honeycomb substrates to occur play, and the stability of honeycomb substrate is affected, and has reduced its working life, thereby has reduced the working life of ternary catalyzing unit.

Summary of the invention

In order to solve the problem of prior art, the utility model embodiment provides a kind of stop ring of ternary catalyzing unit.Described technological scheme is as follows:

The utility model embodiment provides a kind of stop ring of ternary catalyzing unit, and the stop ring of described ternary catalyzing unit is arranged in ternary catalyzing unit,

The stop ring that the stop ring of described ternary catalyzing unit is structure as a whole;

The stop ring of described ternary catalyzing unit comprises stop ring body, is symmetricly set on the stop ring base portion at described stop ring body two end part, with the vertically disposed stop ring protuberance of described stop ring base portion.

Particularly, described stop ring protuberance all fits tightly and is connected with the side of two honeycomb substrates.

The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:

By the stop ring of integrative-structure is set, solve the problem that honeycomb substrate is subjected to displacement, thereby effectively extend the working life of ternary catalyzing unit, and improve the conversion ratio of ternary catalyzing unit.

Brief description of the drawings

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the stop ring of the ternary catalyzing unit of prior art;

Fig. 2 is the stop ring structural representation of the ternary catalyzing unit that provides of the utility model embodiment;

Fig. 3 is the installment state figure of the stop ring of the ternary catalyzing unit that provides of the utility model embodiment.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.

Embodiment

The utility model embodiment provides a kind of stop ring of ternary catalyzing unit, referring to Fig. 2, Fig. 3, the stop ring of ternary catalyzing unit is arranged in ternary catalyzing unit, be used for fixing two honeycomb substrates 4,5, the stop ring that the stop ring of ternary catalyzing unit is structure as a whole, the stop ring 3 of ternary catalyzing unit comprises stop ring body 31, is symmetricly set on the stop ring base portion 32 at stop ring body 31 two end part, with the vertically disposed stop ring protuberance 33 of stop ring base portion 32; Stop ring protuberance 33 all fits tightly and is connected with the side of two honeycomb substrates 4,5.The stop ring of integrative-structure plays fixed cellular carrier, prevents the effect of displacement, makes ternary catalyzing unit not fragile, and increase working life.

Wherein, the ternary catalyzing unit that the utility model embodiment provides has taken into full account under repeatedly shaking, independently stop ring is easily loosening, thereby cause the situation of honeycomb substrate displacement, by two respectively independently stop ring be designed to the stop ring of integral structure, fix two honeycomb substrates simultaneously, ensured honeycomb substrate in ternary catalyzing unit for a long time in stationary state, can not be subjected to displacement phenomenon, thus ensure and extended ternary catalyzing unit working life.

The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:

By the stop ring of integrative-structure is set, solve the problem that honeycomb substrate is subjected to displacement, thereby effectively extend the working life of ternary catalyzing unit, and improve the conversion ratio of ternary catalyzing unit.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
