SUMMARY OF THE INVENTION However, the configuration of the air gun having the retracting mechanism disclosed in the prior art 1 to 4 is to provide a ram at least at the rear of the gun, and a trigger lever or a safety block for transmitting the trigger action. The ram will rotate and strike the striker from the rear to move the striker and the valve pin toward the front of the gun, thereby injecting the gas in the valve body chamber toward the valve pin to perform the launch and retraction of the projectile 9. Therefore, the air gun having the retracting mechanism includes components such as a ram, a safety block, a trigger lever, a supply nozzle, a member for providing a bullet link, and the like, and the like, and the structure is complicated. Further, these members must be operated every time the projectile is fired, and the wear of the member is apt to occur, and the problem of durability and durability is often caused. In addition, the air gun having the retracting mechanism disclosed in the prior art 1 has the function of compressing gas as the force for pushing the cylinder toward the rear of the gun, and then acts on the muzzle side of the bullet, so that the ejection of the bullet nine May occur on the way back from the cylinder. If the launch of the missile 9 is carried out on the way back from the cylinder, the air gun will have a poor elasticity for the mark $E. -8- 201003028 In order to solve the above problems, the present invention provides an air gun having an untwisting mechanism, which is provided with a magazine, a compressed gas source, a sliding member, a cylinder, an inner barrel, a valve body, and a trigger to use a compressed gas to fire an ammunition. Nine, and an air gun having an untwisting mechanism, wherein: the valve body is a valve body chamber capable of sealing and storing a compressed gas supplied from a compressed gas source, and is disposed in the valve body chamber before and after the gun a release valve for moving in the direction; a release valve having a valve through hole penetrating the front and rear direction of the gun, and a gas supply hole for opening or closing the valve body chamber and the valve through hole in the forward and backward direction of the gun; The retraction of the inner barrel causes the release valve to move toward the rear of the gun to open the gas supply hole of the release valve, and the compressed gas is ejected from the valve body chamber toward the valve through hole to perform the ejection and retraction of the bullet nine. effect. The utility model provides an air gun with an untwisting mechanism, which is provided with a magazine, a compressed gas source, a sliding member, a cylinder, an inner barrel, a valve body, a barrel bolt and a trigger, and uses the compressed gas to launch the bomb nine, and has the unloading The air gun of the mechanism is characterized in that: the valve body has a valve body chamber that can seal a space in which compressed gas is supplied from a compressed gas source, and a valve that moves in the valve body chamber in the longitudinal direction of the gun is provided in the valve body chamber; The release valve has a valve through hole 'through the longitudinal direction of the gun and is provided with a valve body chamber and a valve penetrating as it moves toward the front and rear of the gun. L open or closed gas supply hole; and a striker, located on the muzzle side of the release valve, has a needle through hole extending through the front of the gun -9-201003028 and can move toward the front and rear of the gun, with the inner gun The retraction of the tube causes the release valve to move in the direction of the rear of the gun; the action of the barrel latch (acting with the action of the trigger) causes the inner barrel to move 'to move the needle toward the rear of the gun as the inner barrel retreats, The release valve is moved toward the rear of the gun, thereby opening the gas supply hole of the release valve, and the compressed gas is ejected from the valve body chamber toward the valve through hole to perform the launching and untwisting action of the spring 9. According to the present invention, a conventionally used ram of a air gun having an untwisting mechanism, a safety block, a trigger lever, a nail supply member, a member for providing a bullet link, and the like, and the like are not required, and the member thereof is not required. It is less than the conventional technology, so it can reduce the manufacturing cost and reduce the failure caused by these components, and has the effect of improving the durability of the air gun. In addition, the conventional air gun having the retracting mechanism rotates the ram to make the air gun into a launchable state as the sliding member retreats, but the present invention does not allow the ram to rotate when the sliding member retreats. Therefore, the recoil energy of the slider is smaller than conventionally, and the compressed gas can be used more efficiently. Further, the compressed gas of the present invention is different from the prior art 1 in that the projectile 9 can be launched before the cylinder is retracted, so that the deviation of the air gun caused by the cylinder retreat can be suppressed, and the influence on the set elasticity can be reduced. This improves the performance of the air gun.

The high pressure gas container A is a grip provided on the air gun body 1 in this embodiment. 2 is installed in the handle 2, and if the gas supply port C is opened by the pin in the handle 2, the compressed gas in the high pressure gas container A flows into the valve body gas from the gas supply port C through the gas passage. The interior of the chamber 17a is in a state of full state in an initial state. Next, an internal front view showing one cycle of the air gun having the untwisting mechanism of the present embodiment is shown in FIG. 2 to FIG. And Fig. 11 to Fig. 18 (corresponding to a partial enlarged view of Fig. 2 to Fig. 9). Fig. 2 and Fig. 1 show that the user manually performs the state from Fig. 1 The wrench 13 is pulled toward the rear end side of the gun. Thus, the wrench 13 is rotated about the wrench shaft 13 3 a, and the upper front end portion 1 3 b of the wrench 13 abuts the wrench of the barrel bolt 9 The abutting portion 9a is pushed and pushed. At the same time, the barrel casing 8 pushes the barrel spring pad 7 toward the muzzle side. The spring pad 7 will move toward the muzzle side while compressing the barrel spring. At the same time, the inner barrel 5 and the barrel shell 8 will also move toward the muzzle side. The receiver will be shown in Fig. 3 and Fig. 12. 13 further pulls toward the rear end side of the gun. The upper front end portion 1 3b of the trigger 1 3 is disengaged from the -15-201003028 trigger abutment portion 9 a of the barrel latch 9 , and the abutment of the trigger 1 3 and the barrel latch 9 is given. When the state of FIG. 2 and FIG. 1 is released, the spring 9 w is biased toward the upper side of the magazine spring 16 in the magazine 15 and cannot abut against the lower outer peripheral surface of the inner barrel 5 Move to the chamber 11. When the state of the third figure and the twelfth figure is changed, the lower opening portion 1 1 a of the chamber 1 1 is opened as the inner barrel 5 moves toward the muzzle side, and the bullet 9 is opened from the lower opening 1 1 a is inserted into the chamber 1 1 . 4 and FIG. 3, the spring pressure of the barrel spring 6 pushes the barrel spring pad 7 toward the rear end side of the gun as the abutment of the trigger 13 and the barrel latch 9 is released. Make it move. The spring pressure of the barrel spring 6 is transmitted through the barrel spring pad 7, and the inner barrel 5 and the barrel case 8 are integrally moved toward the rear end side of the gun. If the inner barrel 5 is further moved toward the rear end side of the gun, the spring 9 that is attached to the chamber 11 is inserted into the inner diameter from the rear end side of the inner barrel 5. At the same time, the next spring 9 W 2 in the magazine 15 will abut against the outer peripheral surface of the rear end of the inner barrel 5. Next, Fig. 5 and Fig. 14 will be described. The inner barrel 5 is further moved toward the rear end side of the gun from the state of Fig. 4 and Fig. 3 . Thus, the grip end locking portion 7a formed in the lower portion of the barrel spring pad 7 abuts against the barrel spring washer retreat preventing portion 2b formed in the grip 2, and stops moving backward toward the rear end side of the gun. mobile. Although the barrel spring washer 7 has stopped retreating, the inner barrel 5 and the barrel shell 8 continue to move toward the rear end side of the gun due to the inertial force of the movement caused by its own weight, so the barrel spring washer 7 and the barrel shell 8 will separate. -16- 201003028 The inner barrel 5 @ g @ which continues to move rearward by inertial force enters the inner peripheral surface of the chamber 1 1 and then impacts the striker 22, pushing it against the rear side of the gun to move it . Next, Fig. 6 and Fig. 15 will be described. If the inner barrel 5 is retracted and the needle 2 2 is retracted toward the rear of the gun, the release valve 19 fitted with the striker 2 2 is also retracted toward the rear side of the gun. The air supply port 19b communicates with the valve body air chamber 17a as the retreat' flange portion i9a of the relief valve 19 opens the valve gasket 20. The gas filled in the valve body chamber 17a is introduced into the valve through hole 190 through the gas supply hole i9b, and a part of the gas flows into the inner barrel 5 through the needle through passage 22a from the front through hole, and the air pressure thereof is 5 The inside of the bullet nine W is fixed at the muzzle. Then, Fig. 7 and Fig. 16 will be explained. After the valve body air chamber 17a flows into the valve through hole 1 90 through the body supply hole 19b, the other portion flows into the rear through hole 190a, and the cylinder pressure receiving surface 23a is discharged from the rear end of the relief valve 19. Push. By this pressing, both the slider 23 and the slider 3 which is integrally formed with the cylinder 23 are retracted together. When the member 3 and the cylinder 23 are retracted, since the gas in the valve body chamber 17a is continuously discharged against the rim of the retracting spring 12, the slider which is provided at the lower portion of the muzzle side of the slider 3 is continued. When the locking portion 3b abuts against the slider retreat preventing portion 2a of the grip 2, the movement of the slider 3 is stopped. At this time, the residual gas in the cylinder 23 is discharged to the atmosphere from the port side opening portion of the cylinder 23. Then, Fig. 8 and Fig. 7 are explained. When the spring of the retracting spring 12 is received, the slider 3 starts moving forward toward the muzzle side. The forward moving end, the tenth 22 collision will be away from the current flow 190b barrel gas gas mouth cylinder sliding pressure retreat. The gun pressure connected to the reverse -17-201003028 allows the rear portion of the valve body 17 to be inserted into the cylinder 23, and when the cylinder pressure receiving surface 23a in the cylinder 23 abuts against the rear end surface of the valve body 17, the forward movement stops. Next, Fig. 9 and Fig. 18 will be described. If the user leaves the trigger 1 3 from the state of Fig. 8 and Fig. 7 and receives the spring pressure of the trigger spring 14, the trigger 13 will rotate clockwise with the trigger shaft 1 3 a as the center and return. Original position (state of Figure 1). As the trigger 13 returns to its original position, the barrel latch 9 is pushed up by the upper front end portion 14b of the trigger 1 3 . Then, when the barrel case locking portion 9b of the barrel stopper 9 abuts against the barrel latch locking portion 8a of the barrel case 8, the barrel stopper 9 is in a locked state. After returning from the state of FIG. 9 to the initial state of FIG. 1 , the operations of FIGS. 2 to 9 are sequentially performed, and a series of transmission operations can be repeatedly performed.
