Abstract

The invention discloses a bent stormy air gun which is characterized by comprising a spear, a hand slide valve, a high-pressure rubber tube and a quick male connector. The hand slide valve is connected with an air inlet in the bottom of the spear, the high-pressure rubber tube is connected with an air inlet in the bottom of the hand slide valve and is used for delivering air, and the quick male connector is mounted at the bottom of the high-pressure rubber tube and is used for being connected with an air source connector; the spear comprises a hemispherical bent connecting piece, an inflation connector, an air suction tube and a Venturi component, the inflation connector is mounted at the front end of the bent connecting piece, the air suction tube is mounted at the rear end of the bent connecting piece, and the Venturi component is mounted inside the bent connecting piece. The bent stormy air gun has the advantages that the bent stormy air gun is small in structure and is small in occupied space when working; owing to the optional hand slide valve, the labor intensity of operators can be greatly reduced, and the operation time of the operators can be greatly shortened; owing to the design of an overpressure protection function, potential safety hazards of bursting of an inflation bag due to the fact that the inflation bag is excessively inflated can be eliminated.

Description

A kind of elbow storm air gun

Technical field

The present invention relates to the charge gun technical field, particularly a kind of elbow storm air gun.

Background technology

In the logistics transportation process; cause inner cargo damage in order to prevent between container mutually colliding; the staff often can use a kind of Filling air bag; Filling air bag is placed between the container gap; when container jolts, can play certain cushioning effect, effectively absorbing vibration; alleviate the shaking amplitude of container, thereby reach the purpose 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), adopted venturi principle in its disclosed charge gun scheme, 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 adopt 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 charge gun commonly used is larger, and in the time need to working in narrow gap, charge gun commonly used is often longer due to the rifle body, can't fill in gap, and be that inflation work has brought very large difficulty.

And existing charge gun is when inflation, the 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 the filling bag explosion; even can cause casualties when serious, the staff has been brought to great potential safety hazard.

Summary of the invention

The concrete structure of inflation connector 13, can show fully in Fig. 1, specifically comprise: cross thimble 131, front cross 132, rear cross 133, thimble stage clip 134, front cross stage clip 135, the 3rd sealing ring 136, positioning sleeve 137, sealing gasket 138, the 4th sealing ring 139, collar 1312, collar stage clip 1311, back-up ring 1313 and some steel balls 1310, thimble stage clip 134 is enclosed within the rear end of cross thimble 131, front cross 132 and rear cross 133 are contained in respectively the front-end and back-end of cross thimble 131, front cross stage clip 135 is enclosed within on rear cross 133, be placed between front cross 132 and rear cross 133, positioning sleeve 137 is nested in front cross 132 outsides, and be connected with bend connecting fitting 11, the 4th sealing ring 139 is placed in the interface of positioning sleeve 137 and bend connecting fitting 11, sealing gasket 138 is placed in the front of front cross 132, positioning sleeve 137 is provided with some hole of beads, steel ball 1310 is placed in the hole of bead, collar stage clip 1311 is nested on described positioning sleeve 137, be placed in the back in the described hole of bead, back-up ring 1313 is nested on described positioning sleeve 137, be placed in the front in the described hole of bead, collar 1312 is nested in the outside of described positioning sleeve 137.

The internal structure of hand guiding valve 2, referring to Fig. 4 and Fig. 5, specifically is constructed as follows:

Hand guiding valve 2 comprises: body 21 and be enclosed within the sliding sleeve 22 on body; The internal chamber wall two ends of sliding sleeve tighten with body 21 and fit tightly, the outer wall of middle part outwardly convex and body forms an inner chamber body, the two ends of the internal chamber wall of sliding sleeve also are provided with respectively the 5th sealing ring 23 and the 6th sealing ring 24, for strengthening air-tightness and increase the frictional force between sliding sleeve 22 and body 21 outer walls, anti-anti-skid sheath 22 Automatic-fallings; Body 21 inside are comprised of mutual disconnected upper and lower two

parts cavity

211 and 212, the bottom of upper cavity 211 is provided with some air admission holes, the top of lower chamber 212 is provided with some ventholes, body 21 tops are provided with one for limiting the spacing preiection 213 of sliding sleeve slip highest order, and bottom is provided with one for limiting the limited location snap ring 214 of sliding sleeve 22 slip lowest orders.

The operation principle of hand guiding valve 2 is as follows:

When upwards promoting sliding sleeve 22 to highest order, position as shown in Figure 3, now, sliding sleeve 22 is communicated with the venthole of the air admission hole of upper cavity 211 and lower chamber 212 with the cavity between body 21, gas will circulate along the gas circuit shown in Fig. 3, thereby has realized the opening of hand guiding valve.

Then, promote again sliding sleeve 22 downwards to lowest order, position as shown in Figure 4, now, cavity between sliding sleeve 22 and body 21 can not be communicated to the air admission hole of upper cavity 211, and as shown in Figure 4, gas circuit is interrupted in inner chamber, and, due to the obstruct of the 5th sealing ring 23 and the 6th sealing ring 24, not there will be the phenomenon of gas leakage.

Explain over-voltage protecting function of the present invention below in conjunction with Fig. 6 and Fig. 7.

In Fig. 6, the arrow direction indication is, gas circuit trend when the present invention works; During inflation, gas is entered by the hand guiding valve, enters from the active air inlet of rifle head, then is entered by the air admission hole on endless belt, from muzzle, enters Filling air bag, and now, the inboard negative pressuren zone that forms of tongue piece, according to venturi principle; Tongue piece, to internal strain, forms passive air inlet duct; After air bag air pressure reaches the specified air pressure of setting; tongue piece outwards is out of shape; thereby gas outwards flows out from tongue piece; form passive gas outlet; as shown in Fig. 7 arrow points; unnecessary gas just can not continue to rush in air bag, has avoided owing to excessively inflating the air bag explosion caused, thereby has played the function of overvoltage protection.

The above-described preferred embodiment of utilizing describes the present invention in detail, but not limits the scope of the invention.Those skilled in the art can make trickle change and adjustment by after reading the present invention, and the main idea of the present invention of will can yet be regarded as place, also do not break away from the spirit and scope of the present invention.
