Description
Technical field
The utility model relates to a kind of wind fairing head that can be alone or dual-purpose, refer in particular to a kind of singlehanded control and treat that charging air inlet inserts one and connects mouth, the wind fairing head that can directly inflate, whereby greatly to promote operation smoothness and the convenience of alone or dual-purpose wind fairing head when inflating.
Background technique
Previous dual-purpose wind fairing head just as shown in case before No. 095107665th, TaiWan, China application, No. 097203517 etc. patent as,, before this patent, case all has following shortcoming:
One, the front case of this patent is when inflating, must control with a hand holding body and treat that charging air inlet inserts arbitrary mouth that connects, and then utilize an other hand propulsion spanner, with treating charging air inlet so that actuating of moving down of inner cylinder pressure connects mouth folder bundle, finally, just can inflate, this kind of palpus is also not convenient through the pattern of bimanualness, truly has the sense of wasting time and energy.
Two, before this patent case see through that cylinder pressure moves down and nozzle connecting axis forced to move to distortion, with " indirectly ", actuate the folder bundle that connects mouth radial deformation and treat charging air inlet, it is quite limited that this connects mouth radial-deformation, so connect mouth folder bundle, treats that the strength of charging air inlet is quite limited, so when inflating, as easy as rolling off a log have a gas leakage problem.
Three, before this patent, the overall structure of case is really too complicated, causes manufacture and assembly cost to have the shortcoming that cannot reduce.
In view of this, the design people is for not attaining perfect caused many disappearances and inconvenience in above-mentioned wind fairing head structural design, and deeply design, and active research improvement has a fling at and development and Design goes out this case.
Model utility content
The purpose of this utility model be to provide a kind of can be alone single mouth formula wind fairing head and direct press type bivalve mouth automatic switchover wind fairing head that can be dual-purpose, can one-handed operation and the charging air inlet for the treatment of of different types is inflated, can treat charging air inlet by powerful Shu Gu, can the gas leakage situation when inflating be down to minimumly, greatly promote operation smoothness and the convenience of alone or dual-purpose wind fairing head when inflating.
In order to reach above-mentioned purpose, solution of the present utility model is:
