The specific embodiment
Below in conjunction with accompanying drawing, air pistol constant-voltage equipment of the present invention embodiment is further described.
As shown in Figure 1, air pistol constant-voltage equipment of the present invention, comprises gas cylinder Connection Block 1, the decompression body 5 being fixedly 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 shown in Figure 4 and 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, after gas cylinder Connection Block 1 is connected with decompression body 5, described cavity I 101 and cavity II 501 form air supply chamber 13; Dish spring 3 is arranged in air supply chamber 13 after being sleeved on piston rod 61 together with piston 6.
As shown in Figure 4, gas cylinder Connection Block 1 is provided with the first air flue 102 for the inside of one end of being connected with gas cylinder 7, and these the first air flue 102 one end are communicated with the 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 one end are communicated with air supply chamber 13, the other end is communicated with pressure stabilizing chamber 14, the one end being communicated with air supply chamber 13 is preferably set to horn mouth, this bell-mouthed design is not only 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 the second gas port 601, the second air flue 602 and the 3rd air flue 603 being interconnected successively, the second air flue 602 can be identical with the diameter of the 3rd air flue 603, preferably the diameter of the second air flue 602 is less than the diameter of the 3rd air flue 603 in the present embodiment, is convenient to flowing of gases at high pressure when inflation.End at piston rod 61 is also provided with groove 604, as shown in Figure 1, in this groove 604, is provided with sealing gasket 2.The outside of piston rod 61 and pistons end 62 is respectively arranged with cannelure II 605, in this cannelure II 605, is provided with sealing ring 15.
As shown in Figure 4, be also provided with the steam vent 104, first row air flue 105 and the second row air flue 106 that are interconnected successively in gas cylinder Connection Block 1, one end of first row air flue 105 and second row air flue 106 is communicated with air supply chamber 13; Steam vent 104 is arranged between two cannelure I 107.
Below in conjunction with accompanying drawing, describe the course of work of air pistol constant-voltage equipment of the present invention in detail.
As shown in Figure 1, screw 4 is connected gas cylinder Connection Block 1 with decompression body 5 after, dish spring 3 is in compressive state, and piston 6 is under the effect of dish spring 3 spring power, pistons end 62, in the position near the 4th air flue 502, has certain gap between sealing gasket 2 and the first air flue 102.As shown in Figure 2, during inflation, after gas cylinder 7 is connected with this air pistol constant-voltage equipment, gas cylinder valve rod 8 is backed down, gases at high pressure in gas cylinder along the direction of arrow in Fig. 1 successively through the first gas port 103 and the first air flue 102, then through the gap between sealing gasket 2 and the first air flue 102, enter in air supply chamber 13, then again successively after the second gas port 601, the second air flue 602 and the 3rd air flue 603 in piston, by entering pressure stabilizing chamber 14 after the 4th air flue 502.When the air pressure in pressure stabilizing chamber 14 acquires a certain degree, the spring that piston end surface 606 overcomes dish spring 3 under the effect of gas pressure is tried hard to recommend moving piston 6 and is moved to the direction of the first air flue 102, be arranged on the sealing gasket 2 of piston rod 61 ends by the gas outlet sealing of the first air flue 102, gases at high pressure in gas cylinder no longer enter air supply chamber 13, thereby the pressure in air supply chamber 13 and pressure stabilizing chamber 14 is no longer increased, keep constant.
As shown in Figure 2, during locking, cocking, trigger shaft 12 is freed rear shock air valve stem 10 venting, realizes shooting.After air valve stem 10 is clashed into by trigger shaft 12, compressed gas valve spring 9; After having shot, air valve stem 10 resets under the effect of air valve spring 9, thereby pressure stabilizing chamber 14 is airtight.
Simultaneously, because the gas pressure in pressure stabilizing chamber 14 after shooting 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 the first air flue 102 is opened, gases at high pressure in gas cylinder start again to flow in air supply chamber 13 and pressure stabilizing chamber 14, repeat above-mentioned inflation, venting, shooting course.
During inflation, due to piston 6, to overcome the required gas pressure of the spring power of dish spring 3 consistent at every turn, so the gas pressure of pressure stabilizing chamber 14 interior each preshots is also constant, thereby guaranteed fire accuracy.When gas pressure in gas cylinder is not enough, need pulls down gas cylinder it is inflated.
After having competed, pull down gas cylinder, as shown in Figure 3, due to pull down gas cylinder moment air supply chamber 13 and pressure stabilizing chamber 14 in still have gas, the first air flue 102 is the state in sealed pad 2 sealings still, therefore, gas, along the direction of arrow in Fig. 3, is discharged by the second row air flue 106 in gas cylinder Connection Block 1, first row air flue 105 and steam vent 104 successively.
Competed and pulled down after gas cylinder, the interior unnecessary gases at high pressure of air supply chamber 13 and pressure stabilizing chamber 14 can be got rid of, noresidue, and situation about still can fire after having avoided gas cylinder to remove, has got rid of potential safety hazard.
In sum, air pistol constant-voltage equipment of the present invention, can guarantee that shooting meets the bullet amount of match regulation in match or training, and gas pressure is constant while shooting at every turn, has guaranteed fire accuracy.
In addition, owing to being provided with special exhaust passage, in match, complete and pull down after gas cylinder, unnecessary gases at high pressure in air supply chamber and pressure stabilizing chamber can be got rid of, noresidue, situation about still can fire after having avoided gas cylinder to remove, has got rid of potential safety hazard.
This air pistol constant-voltage equipment is simple and compact for structure, easy for installation, stable performance.
