Description

Technical Field

[0001] This utility model relates to the field of shooting equipment, and in particular to a cold self-generated gas crossbow launching device. Background Technology

[0002] The crossbow is an ancient cold weapon and an important component of ancient chariot warfare. It was a powerful long-range weapon in ancient times. A strong crossbow could reach a range of 600 meters, while a large bed crossbow could reach a kilometer. Compared to sniper rifles, modern crossbows have the advantage of being silent and stealthy; compared to bows and arrows, crossbows have stronger penetrating power, longer range, and higher accuracy. However, both ancient and modern crossbows have drawbacks such as long preparation time, large size, and short range for smaller ones. For the structure of a gas crossbow, refer to the Chinese invention patent application number CN201610277360.5, entitled "Compressed Gas Powered Support Arm Crossbow." The cold-launched self-generated gas crossbow is a new type of crossbow launcher designed using low-temperature propellant and cold-launcher structural technology. Compared to traditional crossbows, it lacks the crossbow body and limbs, and its appearance is similar to a traditional gun. Compared to a gun, this device eliminates the sound of firing because the gas produced during launch is not released into the air. Furthermore, the gas generated during launch is absorbed into a gas tank, providing energy for the cylinder's reset. Excess gas is slowly released into the air through multiple mechanisms, eliminating the sound of air release and achieving a silent firing effect. Existing cold, self-generated gas crossbow launching devices suffer from drawbacks such as complex structure and inconvenient operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple, practical and easy-to-operate cold self-generated gas crossbow launching device.

[0019] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figures 1 to 2As shown, the present invention discloses a cold self-generated gas crossbow launching device, including a body 1 and a gas generator 2, a cylinder assembly 3, a trigger 4 and an arrow 5 respectively disposed on the body 1. The gas generator 2 and the arrow 5 are detachably connected to the body 1. The gas generator 2 is connected to the cylinder assembly 3 and the trigger 4 respectively. The cylinder assembly 3 is used to push the arrow 5 to launch.

[0021] As can be seen from the above description, the beneficial effects of this utility model are as follows: A cold self-generated gas crossbow launching device has a simple structural design, mainly including a gas generator 2, a cylinder assembly 3, a trigger 4, and an arrow 5. When in use, the gas generator 2 generates gas to quickly link the cylinder assembly 3 to move forward, thereby pushing the arrow 5 to move forward quickly to complete the firing. Since the gas generation and release processes of the gas generator 2 are realized in a sealed cavity, there is no external gas release, so the firing is silent, simple, practical, and easy to operate.

[0022] In an optional embodiment, the cylinder assembly 3 includes a cylinder body 31 and a gas storage tank 32. The cylinder body 31 is connected to the gas generator 2 and the gas storage tank 32 respectively. A piston is provided inside the cylinder body 31. The piston is connected to a push rod, which is used to push the arrow 5 to launch.

[0023] As can be seen from the above description, the cylinder includes a cylinder body 31 and a gas storage tank 32. During firing, the gas generator 2 generates gas to quickly push the piston and push rod forward, thereby propelling the arrow forward rapidly. When the piston is in position, the gas generated by the gas generator 2 is absorbed by the gas storage tank 32.

[0024] In an optional embodiment, the cylinder body 31 is provided with a first air port and a second air port. The first air port is connected to the gas generator 2, and the second air port is connected to the air storage tank 32. The first air port is provided with a pneumatic valve.

[0025] As described above, during reset, excess gas can be released slowly through multiple release vents within the device, resulting in a silent reset. By switching the pneumatic valve, the cylinder's operating state returns to the reset state. Opening the port connecting the cylinder to the gas generator 2 releases excess gas into the air, and the gas in the gas tank 32 pushes the piston back to reset.

[0026] In an optional embodiment, the cylinder 31 is connected to the gas generator 2 and the gas storage tank 32 respectively via the air guide pipe 6.

[0027] In an optional embodiment, the gas generator 2 includes a generator body 21 and a power supply, both of which are mounted on the body 1 and connected to each other.

[0028] As can be seen from the above description, the power supply plays the role of providing power for system control.

[0029] In an optional embodiment, the fuselage 1 is provided with a guide groove 11 for guiding the arrow 5 and an arrow guide groove 12 perpendicular to the guide groove 11 for mounting the arrow 5.

[0030] As can be seen from the above description, the function of the guide groove 11 is to guide the trajectory of the special arrow, and the function of the arrow feeding groove 12 is to realize semi-automatic or fully automatic arrow feeding.

[0031] In an optional embodiment, the arrow 5 includes an arrow body 51, one end of which is provided with an arrowhead 52, and the outer wall of the other end of the arrow body 51 is provided with a balancing elastic tail fin 53. The other end of the arrow body 51 is provided with a detachable clamping member 54, which covers the outside of the balancing elastic tail fin 53. The outer diameter of the clamping member 54 is smaller than the inner diameter of the guide groove 11.

[0032] As described above, during preparation, the clamping slot tightens the balancing elastic tail fin 53 at the tail, and the balancing elastic tail fin 53 is not deployed. After launch, because the size of the clamping slot is larger than the size of the tail of the guide slot 11, the clamping slot disengages from the elastic tail fin of the balancing elastic tail fin 53, and the balancing elastic tail fin 53 deploys, adjusting the drag center of the arrow to the geometric center of gravity, thereby stabilizing the flight of the arrow body 51. The clamping slot will fall out freely after the arrow body 51 flies out and the push rod in the cylinder assembly 3 retracts.

[0033] In an optional embodiment, the fuselage 1 is provided with a sight for aiming.

[0034] As can be seen from the above description, sights play a role in improving aiming accuracy.

[0035] In an alternative embodiment, the sight is a mechanical sight or an optical sight.

[0036] In an optional embodiment, the fuselage 1 is provided with a stock 13.

[0037] As can be seen from the above description, the stock 13 serves to provide support and thus improve shooting stability.

[0038] Please refer to Figures 1 to 2 As shown, the first embodiment of this utility model is: a cold self-generated gas crossbow launching device, including a body 1 and a gas generator 2, a cylinder assembly 3, a trigger 4 and an arrow 5 respectively disposed on the body 1. The gas generator 2 and the arrow 5 are detachably connected to the body 1. The gas generator 2 is connected to the cylinder assembly 3 and the trigger 4 respectively. The cylinder assembly 3 is used to push the arrow 5 to launch.

[0039] The cylinder assembly 3 includes a cylinder body 31 and a gas storage tank 32. The cylinder body 31 is connected to both the gas generator 2 and the gas storage tank 32. A piston is installed inside the cylinder body 31, and the piston is connected to a push rod, which is used to launch the arrow 5. The cylinder body 31 has a first air port and a second air port. The first air port is connected to the gas generator 2, and the second air port is connected to the gas storage tank 32. The first air port is equipped with a pneumatic valve. The cylinder body 31 is connected to both the gas generator 2 and the gas storage tank 32 via a guide pipe 6. The gas generator 2 includes a generator body 21 and a power supply. Both the generator body 21 and the power supply are mounted on the body 1 and connected to each other. The body 1 has a guide groove 11 for guiding the arrow 5 and an arrow guide groove 12 perpendicular to the guide groove 11 for mounting the arrow 5. The arrow 5 includes an arrow body 51, with an arrowhead 52 at one end and a balancing elastic tail fin 53 on the outer wall of the other end. A detachable clamping member 54 covers the balancing elastic tail fin 53 at the other end of the arrow body 51, and the outer diameter of the clamping member 54 is smaller than the inner diameter of the guide groove 11. The fuselage 1 is equipped with a sight for aiming. The sight can be a mechanical sight or an optical sight. The fuselage 1 is equipped with a stock 13.

[0040] The cold, self-generated gas crossbow launching device of this embodiment resembles a firearm in appearance. It can be operated semi-automatically or fully automatically, with a total length of less than 1000 mm, and less than 600 mm after folding the stock 13. The gas generator 2 adjusts the burning rate of the gas-generating agent inside the gas generator 2 according to the acceleration characteristics of the arrow, quickly and fully accelerating the arrow to the ideal speed. During firing preparation, the power switch is off, and the gas generator 2 is in a safe state. During operation, the power is turned on, and aiming is achieved through mechanical sights, or an external laser red dot sight or optical sight. Pressing the trigger 4 (power switch) initiates the rapid generation of high-pressure, low-temperature gas by the gas generator 2, pushing the piston and simultaneously propelling the arrow forward at high speed. Upon reaching the limit, the high-pressure, low-temperature gas is recovered and stored in the gas tank 32. When piston reset is required, the gas in the gas tank 32 is released, pushing the piston back to its original position, and simultaneously pushing the arrow into place in the magazine, ready for the next firing. A new gas launcher can be used for a new firing.

[0041] In summary, the cold self-generated gas crossbow launching device of this utility model has a simple structural design, mainly including a gas generator, a cylinder assembly, a trigger, and an arrow. In use, the gas generator generates gas to quickly drive the cylinder assembly forward, thereby propelling the arrow forward rapidly to complete the firing. Since the gas generation and release processes of the gas generator are realized in a sealed cavity, there is no external gas release, so the firing is silent. It is simple, practical, and easy to operate.
