The invention discloses a kind of bent stormy air gun, it is characterized in that, the hands guiding valve that including rifle head, is connected with rifle head bottom air inlet, be connected with hands guiding valve bottom air inlet and for the high-pressure rubber pipe of gas transmission be arranged on bottom high-pressure rubber pipe and for the snap joint male being connected with gas source connector；Inflation union joint that described rifle head by a hemispherical bend connecting fitting, is arranged on this bend connecting fitting front end, it is arranged on the suction nozzle of this bend connecting fitting rear end and the venturi component within this bend connecting fitting is installed forms.Present configuration is small and exquisite, takes up room little during work, and the apolegamy of hands guiding valve greatly reduces labor intensity and the operating time of operator, and the design of over-voltage protecting function eliminates the potential safety hazard causing air bag to burst because of inflatable bag inflating excess.
Description
Technical field
The present invention relates to charge gun technical field, particularly to a kind of bent stormy air gun.
Background technology
During logistics transportation; the cargo damage of inside is caused in order to prevent from mutually colliding between container; staff often uses a kind of Filling air bag; Filling air bag is placed between container gap; when container jolts, it is possible to play certain cushioning effect, effectively absorb vibrations; alleviate the shaking amplitude of container, thus the purpose of goods in reaching guard box.
Filling air bag can use a kind of special charge gun when inflation.
Traditional charge gun, its gas outlet is less, and sealing effectiveness is poor, and does not use venturi principle, and therefore, traditional charge gun aeration speed is slow, and often filling an air bag will take a long time, and this greatly reduces work task efficiency.
Patent name is the patent of a kind of Quick inflating gun (publication number: 102352956A), have employed venturi principle, the aeration speed of existing charge gun is promoted to a new level in charge gun scheme disclosed in it.
Nowadays, the aeration speed of charge gun have become as row in an important indicator, often improve 1 second the most difficult.
But personnel's research, nowadays uses the charge gun of venturi principle much after deliberation, but the charge gun that employing venturi principle is made equally, and its aeration speed but has the biggest great disparity.
Conventional its monnolithic case size of charge gun is relatively big, and when needing to work in narrow gap, conventional charge gun is often due to gun body is longer, it is impossible to fills in gap, and is that inflation work brings the biggest difficulty.
And, existing charge gun is when inflation, and workman needs the gas-filled switching tube button always pinning on handle, until Filling air bag is charged to suitable air pressure and can let go.Present arms the most for a long time and actuation of keys; greatly consume the muscle power of staff; virtually greatly reduce the work efficiency rate of staff; and existing charge gun does not has over-pressure safety device; the range estimation of staff and feel experience is relied on to judge during inflation, once inflatable bag inflating excess, it is easily caused filling bag explosion; even can cause casualties time serious, staff is brought great potential safety hazard.
Summary of the invention
