[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] The pneumatic launcher of the present invention includes a gas cylinder 3, multiple constant pressure mechanisms 1, and multiple launch tubes 2, wherein each constant pressure mechanism 1 corresponds to one launch tube 2. The gas cylinder 3 is filled with high-pressure gas, and the gas cylinder 3 is connected to the multiple constant pressure mechanisms 1 through a distribution module 4, so that the gas cylinder 3 can supply gas to the constant pressure mechanisms 1 respectively. Specifically, the distribution module 4... The device has an air inlet 41 and multiple air outlets 42. The side wall of the air inlet 41 has multiple connecting holes 431331, and each connecting hole 431331 corresponds to an air outlet 42. The air outlet 42 is equipped with a gas cylinder 3 and is connected to the air inlet 41. The constant pressure module has a constant pressure chamber 11. One end of the constant pressure chamber 11 is connected to the launch tube 2 through a nozzle 14. The end of the constant pressure mechanism 1 away from the launch tube 2 is inserted into the air outlet 42 of the diversion module 4. An air inlet channel 16 is opened at the end of the constant pressure chamber 11 away from the nozzle 14. The constant pressure chamber 11 is connected to the air outlet 42 of the diversion module 4 through the air inlet channel 16, so that the multiple air outlets 42 and the air inlet 41 are connected in parallel. The axial directions of the air outlets 42, air inlets 41, gas cylinder 3 and launch tube 2 are parallel, thereby reducing the radial volume of the launcher and making it easier to install the launcher on a motion platform such as a drone and control the movement of the launcher.

[0032] An outlet plug 12 and a constant pressure pipe 13 are installed inside the constant pressure chamber 11. The outlet plug 12 and the constant pressure pipe 13 can move along the length of the constant pressure chamber 11. The outlet plug 12 is conical, and its tip can be inserted into the nozzle 14. Specifically, the nozzle 14 includes a connecting port 141 and a pressurizing passage 142, and the diameter of the pressurizing passage 142 is smaller than the diameter of the connecting port 141. The tip of the outlet plug 12 can be inserted into the connecting port 141 and block the connecting port 141. To prevent gas from entering the nozzle 14 from the constant pressure chamber 11, the air intake channel 16 has a receiving hole 161 at one end near the constant pressure chamber 11. Multiple springs 15 are housed within the receiving hole 161, and the springs 15 are arranged in an overlapping manner. A force-bearing ring 132 extends radially outward from one end of the constant pressure tube 13, and the edge of the force-bearing ring 132 is sealed to the edge of the receiving hole 161. The force-bearing ring 132 changes with the air pressure within the constant pressure chamber 11 along the edge of the receiving hole 161. The hole 161 moves axially, and one end of the overlapping spring plates 15 abuts against the bottom of the receiving hole 161, while the other end abuts against the force ring 132. An air inlet plug 133 extends outward from the end of the constant pressure tube 13 near the force ring 132. The air inlet plug 133 is placed inside the receiving hole 161, and its end face abuts against the air inlet channel 16. A through hole 1331, communicating with the interior of the constant pressure tube 13, is opened on the side wall of the air inlet plug 133. A guide post is fixed on the side of the plug away from the tip. The guide post is inserted into the constant pressure tube 13, and its diameter is smaller than the inner diameter of the constant pressure tube 13. The tube opening has an outward flare 131. During operation, after each launch, the air pressure in the constant pressure chamber 11 is at its lowest point, allowing gas from the constant pressure tube 13 to enter the constant pressure chamber 11. The spring 15 in the receiving hole 161 pushes the constant pressure tube 13 into the constant pressure chamber 11, and the air inlet plug 133 opens the air inlet channel 16. Then, the gas in the gas cylinder 3 enters the constant pressure chamber 11 along the diversion module 4, the air inlet channel 16, and the constant pressure tube 13, causing the air pressure in the constant pressure chamber 11 to gradually increase. The force ring 132 squeezes the spring 15. When the air pressure in the constant pressure chamber 11 is greater than the supporting force of the spring 15, the force ring 132 moves into the receiving hole 161 until the air inlet plug 133 blocks the air inlet channel 16, preventing gas from the gas cylinder 3 from entering the constant pressure chamber 11. Thus, the spring 15... The elastic control of the air pressure intensity in the constant pressure chamber 11 prepares for the next launch, while ensuring that the internal air pressure of the constant pressure chamber 11 is the same for each launch, reducing the ballistic difference of each shot, and making it easier for the aiming personnel to control the launcher for aiming.

[0033] In order to quickly block the nozzle 14 after launching objects such as rope nets, a return spring 17 is fitted on the guide rod 121. One end of the spring abuts against the vent plug 12, and the other end abuts against the force ring 132 of the constant pressure tube 13. During operation, the guide rod 121 is attracted by the electromagnetic device, causing the guide rod 121 to move the plug away from the nozzle 14 while compressing the spring. The gas in the constant pressure chamber 11 flows out of the nozzle 14, ejecting the rope net or window-breaking bullet in the launch tube 2 and completing the firing. Afterward, the spring drives the vent plug 12 to reset and block the nozzle 14. At the same time, due to the decrease in air pressure in the constant pressure chamber 11, the spring 15 pushes the constant pressure tube 13, causing the air inlet plug 133 to open the air inlet channel 16, allowing the gas in the gas cylinder 3 to fill the constant pressure chamber 11.

[0034] The launch tube 2 and the nozzle 14 are detachably connected. In this embodiment, a screw connection design is adopted. The rope net or window-breaking projectile to be launched by this launcher is placed in the launch tube 2 in advance, and the rope net is launched by the gas sprayed through the nozzle 14. Those skilled in the art should know that the rope net needs to be folded and stored in advance before being placed in the launch tube, so as to achieve the effect of the rope net unfolding after launch. The folding and storage method of the rope net is consistent with the existing folding and storage method of the rope net in the weapon used to launch rope nets, and will not be described in detail here.

[0035] The electromagnetic device used to control the movement of the vent plug 12 can be set in the constant pressure chamber 11 or the diversion module 4, or it can be formed by winding a coil around the outside of the transmission path, or by winding a coil around the outside of the constant pressure tube 13. It can achieve the purpose of attracting the movement of the vent plug 12. Its specific power supply method and its own structure should be public technology known to those skilled in the art, and will not be described in detail here.

[0036] In order to facilitate the control and observation of the gas pressure in the constant pressure chamber 11, a pressure gauge is provided on the constant pressure chamber 11.

[0037] The pneumatic launcher of this invention allows for the installation of aiming, signal transmission, and reception equipment on one side of the launcher during use. This enables the operator to remotely control the launcher to aim at the target. The specific methods of signal transmission and remote control of the equipment are common knowledge to those skilled in the art and will not be elaborated upon here. After aiming is complete, the electromagnetic device can be activated, attracting the exhaust plug 12 to move and opening the nozzle 14, allowing gas to be ejected and completing the launch. Simultaneously, the intake plug 133 moves, opening the intake channel 16 and allowing gas to be pumped into the constant pressure chamber 11 through the gas cylinder 3 until a preset pressure is reached. The spring 15 is then compressed by the air pressure, and the intake plug 133 blocks the intake channel 16, completing the inflation process and preparing for the next shot.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
