The inner wall of the support pad matches with annular groove one, has gap between outer wall and annular groove two.
The outer wall of the support pad is provided with annular ball groove, is matched with and several abuts with annular groove two in annular ball groove
Ball.
Annular slider is provided in the annular mounting groove and between gasket.
The inside and outside diameter of the annular slider is respectively smaller than the inside and outside diameter of annular mounting groove.
The internal diameter of the hole card spring is more than the aperture of connecting hole one.
The ball and annular slider are all made of polytetrafluoroethylene material.
It is described the utility model has the beneficial effects that：
Compared with conventional art, ring connector is fixed in nut by the utility model by fixed cover, and gasket is logical
It crosses hole card spring and is fixed in the annular mounting groove of bamboo connector, therefore can be gradually after the damage of the gasket of tire pressure pipe fitting
Dismounting is replaced；It is arranged on the annular groove one of bamboo connector and is in two matched support pad of annular groove, support pad
It can abut in connecting hole two and with the realization of step two, spring is provided between support pad and fixation, when detecting tire pressure, tire
After gas nozzle is abutted with the gasket of tire pressure pipe fitting, excessive abutting dynamics compresses bullet by support pad on bamboo connector between the two
Spring, to which into row buffering, such gasket would not be deformed damage because the dynamics that cranked tire valve abuts is excessive, while bullet
The reaction force of spring can also increase the leakproofness abutted between gasket and cranked tire valve；
Compared with conventional art, the utility model is provided with annular slider between gasket and annular mounting groove, when close
When abutting to a certain extent between packing and cranked tire valve, opposite turn can occur between gasket and bamboo connector by annular slider
It is dynamic, and gasket is static relative to cranked tire valve, will not thus cause to rotate between gasket and cranked tire valve
Friction, the damage for effectively avoiding gasket too fast because of pivoting friction；It is provided with ball between support pad and annular groove two,
Avoid that interim card occurs between annular groove during support pad moves, ensure mobile smooth-going, simultaneously support gasket and
Ball is all made of to compare wear resistant smooth using polytetrafluoroethylene material.
