Diameter of the diameter of the upper inwall less than lower inwall；
The upper V-groove includes two symmetrically arranged upper oblique line section cell walls, by upper arc between two upper oblique line section cell walls
Line segment cell wall connects, upper oblique line section cell wall be 40～50 ° with the inclined angle alpha of horizontal plane；
The lower V-groove includes lower vertical section cell wall and oblique line segment cell wall, lower vertical section cell wall and oblique line segment cell wall
Between by lower arc cell wall connect, lower vertical section cell wall perpendicular to shield ring body lower surface arrange, oblique line segment cell wall with
The angle of inclination beta of horizontal plane is 40～50 °；
The cannelure includes horizontal segment cell wall, vertical section cell wall, oblique line section cell wall and lower horizontal segment cell wall, upper level
Section cell wall and lower horizontal segment cell wall are arranged perpendicular to shroud ring body outer wall.
Further, described inclined angle alpha is 45 °.
Further, described angle of inclination beta is 43 °.
Further, length of the length of described upper horizontal segment cell wall more than lower horizontal segment cell wall.
The invention has the beneficial effects as follows：Present configuration is simple, reasonable in design, easy to operate；Shroud ring inner body wall by
Stepped upper inwall and lower inwall composition, shroud ring body upper surface offer V-groove, and shield ring body lower surface is opened
The lower V-groove of ring-type is provided with, the vertical car of shroud ring body outer wall has cannelure, and the diameter of upper inwall is less than the diameter of lower inwall,
This structure precision is higher, easy to process, and error is less so that shroud ring coordinates tight with internal combustion engine part, and good dustproof effect makes
With life-span length, it is not necessary to which Jing is often changed, improve production efficiency is cost-effective.
