When the rear seat member 20 is positioned at the foremost end of the impact simulation chamber 10, the second mechanical seal portion is positioned in front of the first exhaust hole 44 and the second exhaust hole 45, and only allows gas to be output from the pin outlet hole 42 during the process of filling the high-pressure gas into the gas passage 43; when the rear seat member 20 moves to the rear end of the impact simulation cavity 10, the first exhaust hole 44 and the second exhaust hole 45 move out of the valve cavity, the first exhaust hole 44 and the second exhaust hole 45 are respectively used for exhausting high-pressure gas in the gas channel 43 and the valve cavity 21 after moving out of the valve cavity, because the first exhaust hole 44 is separated from the valve cavity 21 before the second exhaust hole 45, the high-pressure gas can be quickly exhausted from the first exhaust hole 44, the generated sound simulates the sound explosion effect, in fact, through reasonably setting the ratio of the inner diameter of the first exhaust hole 44 to the inner diameter of the valve needle 40, the vivid sound explosion effect can be realized, and the sound effect is more suitable for the sound effect of actual firing of a firearm. Wherein, the second mechanical seal part is an O-shaped seal ring.

Referring to fig. 5, 6, 11 and 17, the limit section 211 of the valve cavity 21 is assembled with the striker 30, and the striker 30 is used for directly receiving an external force and conducting the force to the valve element 121 through the valve needle 40. The front end outer diameter of the striker 30 is larger than the rear end outer diameter, the front end of the striker 30 is slidably fitted in the valve cavity 21 between the stopper section 211 and the needle 40, and the front end of the striker 30 and the stopper section 211 form a stopper fit, so that the striker 30 is always restricted in the valve cavity 21 and cannot be separated from the rear seat member 20 when moving backward. The rear end of the striker pin 30 is slidably fitted in the stopper section 211 and extends rearward to the outside of the backseat member 20. The portion of the striker 30 extending to the outside of the rear seat member 20 is used for retracting into the limiting section 211 when receiving the external force, and further the valve needle 40 is abutted against the valve core 121 to be separated from the air outlet 1232 of the air valve 12, so as to realize the conduction of the air valve 12. The front end of the striker 30 is in abutting engagement with the rear end face of the needle 40 when the rear seat member 20 is at the front limit position in the impact simulation chamber 10, and at this time, the length of the striker 30 extending to the outside of the rear seat member 20 is consistent with the stroke of the valve element 121 required for the valve 12 to be conducted.

When the firing pin 30 is impacted, the valve pin 40 is driven to abut against the valve core 121, so that the air valve 12 is conducted; valve needle 40 guides high-pressure gas of high-pressure gas source to get into air flue 43 by going into pinhole 41 when pneumatic valve 12 switches on, export and strike rear seat spare 20 by gas play pinhole 42 again, force rear seat spare 20 to the back extreme position motion of assaulting simulation chamber 10, it is stifled and produce recoil impact effect to strike the tail that is located the rear end of simulation chamber 10 for the recoil of simulation real firearms when the percussion, make the emulation firearms of pneumatic form can have the recoil effect that more is close to real firearms at the shooting in-process, make the training effect of shooting more effective.

Referring to fig. 2 and 3, a partial needle section of the valve needle 40 close to the valve element 121 is set to be a conical needle section, referring to fig. 3, the conical needle section is correspondingly arranged at the air outlet 1232, the outer diameter of the conical needle section is reduced along the length direction of the valve needle 40 close to the valve element 121, so that a gradually increasing gap is formed between the outer circumferential surface of the conical needle section and the inner wall of the air outlet 1232, the gap forms an exhaust flow channel for high-pressure gas to enter the needle hole 41, and the needle hole 41 is arranged at the conical needle section. Through setting up the toper needle section, be favorable to reducing the required stroke of case 121 when opening pneumatic valve 12, only need case 121 and the preceding terminal surface of venthole 1232 to have when less gap this moment, just can allow pneumatic valve 12 to switch on, correspondingly, striker 30 needs the length of exposing outside rear seat spare 20 under initial condition can further reduce to reduce the space occupation of impact simulation device along the firearm fore-and-aft direction in casing 70.

Further, referring to fig. 3 and 11, the needle inlet holes 41 are preferably arranged in a plurality, such as three needle inlet holes 41, at intervals along the circumferential direction of the valve needle 40; preferably, an annular buffer groove 12322 is further formed in the inner wall of the air outlet 1232 along the circumferential direction, and the buffer groove 12322 is disposed corresponding to the air inlet 41. When the air valve 12 is switched on, high-pressure gas firstly moves backwards along the hole depth direction of the air outlet hole 1232, then is intercepted due to the sealing effect of the first mechanical sealing part 12321, and then is temporarily gathered in the buffer storage groove 12322, the buffer storage groove 12322 can uniformly distribute the high-pressure gas released by the air outlet hole 1232 to each needle inlet hole 41, so that the high-pressure gas is synchronously filled into the air passage 43 from each needle inlet hole 41, the efficiency of the gas entering the valve needle 40 is improved, and the firing efficiency is improved. If the simulation firearm is applied to the simulation firearm, the simulation firearm has the advantage that the recoil and the sonic boom effect can occur with less reaction time after the trigger is pulled, so that the shooting effect is more vivid.

Of course, in order to produce the sonic boom effect, the first exhaust hole 44 and the second exhaust hole 45 may not be provided, that is, the valve needle 40 only has the inlet needle 41, the outlet needle 42 and the inner air passage 43, and the length of the valve needle 40 is shorter than that of the valve needle 40 in the above-mentioned embodiment, so as to ensure that the rear end of the valve needle 40 just moves out of the valve cavity 21 while the rear seat member 20 hits the tail plug 11, and a gap for exhaust is formed between the rear seat member 20 and the rear end of the valve needle 40. The sonic boom effect can also be produced by rapid venting through this gap.

Referring to fig. 5 and 6, the tail plug 11 is preferably detachably mounted at the rear end of the impact simulation chamber 10, because the tail plug 11 is required to receive the impact of the rear seat member 20 to generate recoil at each shot, so that the rear seat member 20 is likely to need to be replaced after a period of use, and the detachable mounting is obviously convenient for replacing the tail plug 11.

The reason that the recoil part 20 can be forced to move backwards after being impacted by the high-pressure gas is that after the high-pressure gas is output from the needle outlet 42 of the valve needle 40, the high-pressure gas directly impacts the front end face of the gas needle 30 to force the striker 30 to move backwards, so that the striker 30 abuts against the recoil part 20 and drives the recoil part 20 to move towards the rear end of the impact simulation cavity 10, in the process, the rear end of the striker 30 extends out of the recoil part 20 to prevent the striker 30 from being damaged by the impact of the tail plug 11 and the striker 30, therefore, a containing groove 112 is arranged on the tail plug 11 corresponding to the striker 30 and used for temporarily containing an extending part of the rear end of the striker 30, and the depth of the containing groove 112 is matched with the length of the striker 30 extending out of the recoil part 20 when the recoil part 20 is reset.

Referring to fig. 5 and 6, an O-ring is disposed between the large end of the striker 30 and the limiting section 211 to form a seal between the striker 30 and the limiting section 211, so that the recoil assembly 20 can sufficiently receive the impact force generated by the high pressure gas, thereby simulating a better recoil impact effect.

When the shift shaft 68 is set to the automatic mode, the first sear 621 and the second sear 622 are deactivated, and the full-automatic sear 65 is automatically triggered by the rear seat member 20.

In the initial use or manual mode, manual loading by manually pulling the puller handle 231 back at each shot is required. The loading process is as follows: an operator pulls the puller handle 231 towards the rear end of the air storage chamber 50, when the puller handle 231 moves, the recoil rod 23 and the connecting seat 24 pull the rear seat member 20 towards the rear of the impact simulation cavity 10, in the process, the rear seat member 20 can extrude the lower hammer 61, the hammer 61 is pushed into the lock groove 623 between the first iron resistor 621 and the second iron resistor 622, the lock head 611 on the hammer 61 is clamped into the lock groove 623 formed by the first iron resistor 621 and the second iron resistor 622, the locking of the hammer 61 is completed, and the 'loading' is completed. In this state, the power accumulating assembly 67 connected to the hammer 61 is just in the energy accumulating state, and the compression spring as the first returning member is also compressed. When the operator releases the pulling handle 231, the compression spring returns to the natural state, and pulls the pulling handle 231, the recoil rod 23, the connecting seat 24 and the rear seat member 20 forward, and if the locking head 611 of the hammer 61 is disengaged from the locking groove 623, the rear seat member 20 will move forward under the elastic restoring force of the compression spring until the rear seat member 20 returns to the initial position (the foremost end of the impact simulation chamber 10), and in the initial position, the rear seat member 20 abuts against the valve core base 123 of the air valve 12 and keeps the striker 30 and the needle 40 inserted into the valve cavity 21 of the rear seat member 20, and the rear end of the striker 30 protrudes rearward from the valve cavity 21. When waiting for the operator to fire, the hammer 61 is released and then strikes the rear end surface of the striker 30, so that the rear end of the striker 30 is retracted into the valve chamber 21, and then the gas valve 12 is opened, and high-pressure gas is injected into the valve chamber through the valve needle by the gas valve 12 being conducted, so that the rear seat member 20 is forced to move toward the rear limit position of the impact simulation chamber 10.

In this embodiment, there is no real cartridge clip, but only the shape of the cartridge clip, so-called "loading", is actually to pull the handle 231 to move the rear seat 20 backward, and push the hammer 61 into the lock slot 623 to achieve the locked state, so as to prepare for the next firing.

The pneumatic shooting equipment that this embodiment provided can simulate the recoil and the sound effect of real firearms vividly through pneumatic mechanism, improves the use experience and the training effect of the simulated shooting equipment of production by a wide margin. Meanwhile, due to the adoption of the pneumatic mechanism, the service life of the shooting simulator is greatly prolonged, and the use cost is greatly reduced. The pneumatic shooting equipment can also truly simulate the automatic loading of a full-automatic gun and the switching process of a manual mode and a full-automatic mode, and further improves the use experience and the simulation effect of equipment. The pneumatic shooting equipment in the embodiment has higher universality, and can be assembled into different types of full-automatic firearms by virtue of small-amplitude structural improvement and matching with different types of profile modeling shells.
