Abstract
The utility model discloses a bend storm air gun which is characterized by comprising a gun head, a hand sliding valve connected with an air inlet in the bottom of the gun head, a high-pressure rubber pipe connected with the air inlet in the bottom of the hand sliding valve and used for conveying air and a quick connector male head installed at the bottom of the high-pressure rubber pipe and used for being linked up with an air source connector. The gun head is composed of a hemi-spherical bend connecting part, an inflation connector installed at the front end of the bend connecting part, an air sucking pipe installed at the rear end of the bend connecting part and a venturi component installed in the bend connecting part. The bend storm air gun is small and ingenious in structure, the space occupied in operation is small, because of the hand sliding valve, labor intensity of an operator is greatly reduced, operation time is greatly shortened, and safety hidden risks caused by the fact that an inflation bag explodes due to the fact that the inflation bag is exceedingly inflated are eliminated by the adoption of the design of a overpressure protection function.
Description
Technical field
The utility model relates to charge gun technical field, particularly a kind of elbow storm air gun.
Background technology
In logistics transportation process; in order to prevent mutual collision between container, cause inner cargo damage; staff often can use a kind of Filling air bag; Filling air bag is placed between container gap; when container jolts, can play certain cushioning effect, effectively absorbing vibration; alleviate the shaking amplitude of container, thereby reach the object of goods in guard box.
Filling air bag can be used a kind of charge gun of special use when inflation.
Traditional charge gun, its gas outlet is less, and sealing effectiveness is poor, and does not adopt venturi principle, and therefore, traditional charge gun aeration speed is slow, often fills an air bag and all will spend long time, and this greatly reduces workman's operating efficiency.
Patent name be a kind of Quick inflating gun (publication number: patent 102352956A), in its disclosed charge gun scheme, adopted venturi principle, the aeration speed of existing charge gun is promoted to a new level.
Nowadays, the aeration speed of charge gun has become an important indicator in row, and every raising 1 second is all very difficult.
But personnel's research after deliberation, nowadays adopts the charge gun of venturi principle a lot, but the same charge gun that adopts venturi principle to make, and its aeration speed but has very large great disparity.
Its monnolithic case size of conventional charge gun is larger, and in the time need to working in narrow gap, conventional charge gun is often longer due to rifle body, cannot fill in gap, and be that inflation work has brought very large difficulty.
And existing charge gun is when inflation, workman need to pin the gas-filled switching tube button on handle always, until Filling air bag is charged to suitable air pressure, can let go.Long like this presenting arms and actuation of keys; greatly consumed staff's muscle power; virtually greatly reduce staff's work efficiency rate; and existing charge gun does not have over-pressure safety device; during inflation, rely on staff's range estimation and feel experience to judge, once inflatable bag inflating is excessive, easily cause filling bag explosion; when serious, even can cause casualties, staff has been brought to great potential safety hazard.
