Abstract

The invention discloses a rubber sealing device for a pressure increasing valve of an automobile brake device. The rubber sealing device comprises an outer side sealing ring body, an inner side adjusting ring body, a bottom connecting ring body and a rotary adjusting mechanism. For the rubber sealing device disclosed by the invention, a whole sealing main body is composed of the outer side sealingring body, the inner side adjusting ring body and the bottom connecting ring body, and the bottom connecting ring body is connected to the lower end between the outer side sealing ring body and the inner side adjusting ring body, so that the outer side sealing ring body, the inner side adjusting ring body and the bottom connecting ring body can define an adjusting annular groove; the adjusting annular groove enables radial extrusion strengths of the outer side sealing ring body and the inner side adjusting ring body to get an adjusting space; and an adjusting threaded column drives an abutting head to extrude the inner side adjusting ring body by rotating the adjusting threaded column, so that the outward extrusion strengths of the outer side sealing ring body and the inner side adjustingring body are improved, and then the sealing effect is greatly improved.

Description

technical field [0001] The invention relates to a rubber sealing device for a booster valve of an automobile braking device. Background technique [0002] The car braking device compulsorily decelerates until the car stops during the driving process, or maintains a certain speed when the car goes down a long slope to ensure that the car can stop on the slope reliably. The vacuum booster is the key device of the braking system. The booster valve is an auxiliary booster device for the vacuum booster. With the improvement of domestic automobile safety regulations and the enhancement of people's safety awareness, the booster valve of the vacuum booster is becoming more and more important, and the gasket for the booster valve is also It is its key component; the existing sealing device is generally an annular gasket structure, its structural abutment strength cannot be adjusted, and the radial extrusion strength itself cannot be adjusted, which makes the sealing effect unsatisfac...
