Spring 36.When the inflation of gas-flow closure circle is not very sufficient, be conducive to driving the rotation of swivel, but be unfavorable for high-performance sealed；Inflation
When sealing ring inflation is very sufficient, sealing effectiveness is fabulous, but (friction is big, rotate laborious, and fills now to be unfavorable for driving the rotation of swivel
The very sufficient sealing ring of gas easily causes to scrape damage because driving the relative rotation of swivel and adjustment hole, extrudes impaired).And actually used
In, seldom (accounting is extremely low), under most times, car key is motionless to the rotation time of car key, is not even inserted in
In key hole.Scheme in the present embodiment, it is possible to allow the inflation of gas-flow closure circle very sufficient when car key need not be moved,
Prolonged high leakproofness is ensured, and when car key is rotated (when driving swivel to rotate), the appropriate degree for reducing inflation is reduced
The rotation difficulty for rotating is driven, while reducing the impaired possibility of gas-flow closure circle.It is described as follows：After car key is inserted, need
Continuation inwardly promotes car key so as to press pressure regulation bar, pressure regulation bar is moved towards outside adjustment hole, and by cross bar band piston
Push rod is moved together, and piston push rod drives and pushes away the movement of gas piston, now air cavity volume increase (pushing away gas spring to be compressed), due to gas
Chamber with connected with charging connector by conduit, so a part of gas flow to air cavity in gas-flow closure circle, the tensioning of gas-flow closure circle
Degree is reduced, now beneficial to the rotation for driving swivel；When not rotating, gas piston reset is pushed away in the presence of gas spring is pushed away, pushed away
During gas piston reset, the outside rollback a small distance of car key is driven by piston push rod, cross bar, pressure regulation bar, and while air cavity
Interior a part of gas is also pressed towards gas-flow closure circle, and gas-flow closure circle is fully heaved, is tensioned, and can maintain high sealing at ordinary times
Property.
