As shown in Figure 1, air pistol constant-voltage equipment of the present utility model comprises gas cylinder Connection Block 1, the decompression body 5 of fixedlying connected with this gas cylinder Connection Block 1, and in the present embodiment, gas cylinder Connection Block 1 is connected by screw 4 with decompression body 5.
As Fig. 4 and shown in Figure 6, gas cylinder Connection Block 1 is respectively arranged with cavity I 101 and cavity II 501 with the inside of decompression body 5.As shown in Figure 1, gas cylinder Connection Block 1 is after body 5 is connected with decompression, described cavity I 101 and cavity II 501 formation air supply chambers 13; Dish spring 3 is sleeved on the piston rod 61 back in piston 6 is installed in air supply chamber 13.
As shown in Figure 4, gas cylinder Connection Block 1 is provided with first air flue 102 for the inside of an end that is connected with gas cylinder 7, and these first air flue, 102 1 ends are communicated with first gas port 103, and the other end is communicated with air supply chamber 13; Outer setting has cannelure I 107, as shown in Figure 1, in this cannelure I 107 sealing ring 15 is installed.
As shown in Figure 6, the inside of decompression body 5 is provided with the 4th air flue 502.As shown in Figure 2, the 4th air flue 502 1 ends are communicated with air supply chamber 13, the other end is communicated with pressure stabilizing chamber 14, an end that is communicated with air supply chamber 13 preferably is set to horn mouth, this bell-mouthed design not only is convenient to gases at high pressure and is flowed to the 4th air flue 502 from the 3rd air flue 603, has also increased the lifting surface area of gas to piston end surface 606 simultaneously.
As shown in Figure 5, piston 6 is provided with second gas port 601, second air flue 602 and the 3rd air flue 603 that is interconnected successively, the diameter of second air flue 602 and the 3rd air flue 603 can be identical, the diameter of preferred second air flue 602 is convenient to flowing of gases at high pressure less than the diameter of the 3rd air flue 603 when inflation in the present embodiment.End at piston rod 61 also is provided with groove 604, as shown in Figure 1, is provided with sealing gasket 2 in this groove 604.The outside of piston rod 61 and pistons end 62 is respectively arranged with cannelure II 605, is provided with sealing ring 15 in this cannelure II 605.
As shown in Figure 4, an end that also is provided with the steam vent 104, first exhaust duct 105 and second exhaust duct, 106, the first exhaust ducts 105 and second exhaust duct 106 that are interconnected successively in the gas cylinder Connection Block 1 is communicated with air supply chamber 13; Steam vent 104 is arranged between two cannelure I 107.
Describe the course of work of air pistol constant-voltage equipment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, screw 4 is after body 5 is connected with decompression with gas cylinder Connection Block 1, and dish spring 3 is in compressive state, and piston 6 is under the effect of dish spring 3 spring power, pistons end 62 is in the position near the 4th air flue 502, between sealing gasket 2 and first air flue 102 certain slit is arranged.As shown in Figure 2, during inflation, with gas cylinder 7 with after this air pistol constant-voltage equipment is connected, gas cylinder valve rod 8 is backed down, gases at high pressure in the gas cylinder along the direction of arrow among Fig. 1 successively through first gas port 103 and first air flue 102, enter in the air supply chamber 13 through the slit between sealing gasket 2 and first air flue 102 then, pass through piston interior second gas port 601, second air flue 602 and the 3rd air flue 603 then again successively after, by entering pressure stabilizing chamber 14 behind the 4th air flue 502.When the air pressure in the pressure stabilizing chamber 14 acquires a certain degree, piston end surface 606 overcomes dish spring 3 under the effect of gas pressure spring is tried hard to recommend moving piston 6 and is moved to the direction of first air flue 102, be installed in the sealing gasket 2 of piston rod 61 ends with the gas outlet sealing of first air flue 102, gases at high pressure in the gas cylinder no longer enter air supply chamber 13, thereby the pressure in air supply chamber 13 and the pressure stabilizing chamber 14 is no longer increased, keep constant.
As shown in Figure 2, during locking, cocking, trigger shaft 12 are freed back bump air valve stem 10 venting, realize shooting.After air valve stem 10 is clashed into by trigger shaft 12, compressed gas valve spring 9; After shooting was finished, air valve stem 10 resetted under the effect of air valve spring 9, thereby pressure stabilizing chamber 14 is airtight.
Simultaneously, because the gas pressure in the shooting back pressure stabilizing chamber 14 reduces, piston 6 moves to the direction of the 4th air flue 502 under the effect of dish spring 3, thereby the gas outlet of first air flue 102 is opened, gases at high pressure in the gas cylinder begin again to flow in air supply chamber 13 and the pressure stabilizing chamber 14, repeat above-mentioned inflation, venting, shooting course.
During inflation, because piston 6 overcomes the required gas pressure unanimity of spring power of dish spring 3 at every turn, so the gas pressure of each preshot also is constant in the pressure stabilizing chamber 14, thereby has guaranteed fire accuracy.When the gas pressure in the gas cylinder is not enough, need pulls down gas cylinder it is inflated.
After match is finished, pull down gas cylinder, as shown in Figure 3, since pull down gas cylinder moment air supply chamber 13 and pressure stabilizing chamber 14 in still have gas, first air flue 102 still is in the state of sealed pad 2 sealings, therefore, gas is discharged by second exhaust duct 106 in the gas cylinder Connection Block 1, first exhaust duct 105 and steam vent 104 successively along the direction of arrow among Fig. 3.
After match was finished and pulled down gas cylinder, unnecessary gases at high pressure can be got rid of in air supply chamber 13 and the pressure stabilizing chamber 14, noresidue, and situation about still can fire after having avoided gas cylinder to remove has been got rid of potential safety hazard.
In sum, air pistol constant-voltage equipment of the present utility model can guarantee that shooting meets the bullet amount of match regulation in match or training, and gas pressure is constant when shooting at every turn, has guaranteed fire accuracy.
In addition owing to be provided with special exhaust passage, match finish pull down gas cylinder after, unnecessary gases at high pressure in air supply chamber and the pressure stabilizing chamber can be got rid of, noresidue, situation about still can fire after having avoided gas cylinder to remove has been got rid of potential safety hazard.
This air pistol constant-voltage equipment is simple and compact for structure, easy for installation, stable performance.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described; although with reference to preferred embodiment the utility model is had been described in detail; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model; and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the protection domain of the present utility model.
