Abstract
The utility model discloses a kind of vacuum booster airtight construction, comprise housing, be arranged on the plinth on housing, and the vacuum lamp be connected on plinth, described housing is stepped hole for the through hole of erection joint seat, described plinth is provided with first boss corresponding with described stepped hole and second boss corresponding with housing exterior walls; The outer wall that described vacuum lamp contacts with plinth is provided with the barb of multiple ratchet-like, is also provided with the flange part be connected on described second boss.By the first boss and coordinating and the second boss and coordinating between housing exterior walls between stepped hole, form double sealing surface, strengthen the sealing property between plinth and housing, simultaneously, vacuum lamp outer wall is contacted by barb with between plinth, barb can enlarge active surface, ensures leak tightness, can prevent vacuum lamp from being extracted easily simultaneously.
Description
Technical field
The utility model relates to a kind of vacuum booster airtight construction, belongs to automobile technical field.
Background technology
Brake system effect is in the car very important, the traffic safety of people can be ensured, and the vitals of brake system is vacuum booster, its principle is the vacuum utilizing automotive engine or vacuum pump to produce, by the change of the difference of pressure between two different operating chamber epitheliums in a housing, play the effect of the thrust increasing master brake cylinder.Traditional vacuum booster and the connection pipe of driving engine there will be the problem of gas leakage, cause servo-unit to brake and react reduction.
Summary of the invention
For solving the problem, the utility model provides a kind of structure simple, the vacuum booster airtight construction that air-tightness is good.
The technical scheme that the utility model adopts for its problem of solution is:
A kind of vacuum booster airtight construction, comprise housing, be arranged on the plinth on housing, and the vacuum lamp be connected on plinth, described housing is stepped hole for the through hole of erection joint seat, described plinth is provided with first boss corresponding with described stepped hole and second boss corresponding with housing exterior walls; The outer wall that described vacuum lamp contacts with plinth is provided with the barb of multiple ratchet-like, is also provided with the flange part be connected on described second boss.
Preferably, the other end lateral wall of described vacuum lamp arranges a circle convex closure.
Further, the other end of described vacuum lamp is arranged with protecting sleeve.
The beneficial effects of the utility model are: by the first boss and coordinating and the second boss and coordinating between housing exterior walls between stepped hole, form double sealing surface, strengthen the sealing property between plinth and housing, simultaneously, vacuum lamp outer wall is contacted by barb with between plinth, barb can enlarge active surface, ensures leak tightness, can prevent vacuum lamp from being extracted easily simultaneously.
