Description

Technical Field

[0001] This utility model belongs to the field of simulation teaching aids technology, specifically to a loading and firing structure for a simulated artillery. Background Technology

[0002] As China's military strength continues to grow and its military capabilities continue to improve, a number of military enthusiasts have emerged across the country, and many military simulation bases have sprung up in various places, mainly for family trips or hobbies.

[0003] Water rockets, also known as pneumatic water-jet rockets or water-propelled rockets, work by injecting gas into a sealed rocket body filled with water. As the gas pressure inside the rocket body increases, it bursts open the stopper at the bottom of the bottle, causing water to spray out rapidly and giving the rocket body an upward thrust. The rocket body rises and is launched like a rocket, hence the name water rocket. Based on the principle of water rockets, simulation teaching aids such as rocket launchers, mortars, and artillery can be made.

[0004] However, as a teaching aid, simulated artillery not only needs to be as realistic in appearance as possible, but its operation also needs to be as similar as possible to the actual operation in order to achieve better teaching results and provide a better user experience. The current simulated artillery does not have an ideal imitation effect and still needs to be improved. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a loading and firing structure for a simulated artillery piece. This application provides the following technical solution:

[0006] The device includes a gun body, a gun barrel mounted on the gun body, a shell loaded in the gun barrel, a launching base mounted on the tail of the shell, the launching base being detachably snapped into the gun barrel, and an excitation structure provided in the gun barrel for triggering the launching base to launch the shell.

[0007] The launching base includes a one-way valve communicating with the projectile, a breech cover is installed at the breech end of the gun barrel, and an inflation device is also provided on the gun body. The inflation device includes an inflation head installed inside the breech cover, and the inflation head is sealed and plugged into the one-way valve.

[0008] The launching base includes a ball bearing holder, which is equipped with a water and air supply pipe connected to the one-way valve. The ball bearing holder has several balls for securing the projectile. The ball bearing holder is covered with a sliding sleeve for controlling the movement of the balls. The sliding sleeve reciprocates along the ball bearing holder to move the balls away from and secure the projectile.

[0009] The barrel is provided with a mounting groove, and a retaining plate is fixed on the ball bearing seat. The retaining plate is provided with multiple protrusions around its perimeter. The mounting groove is provided with an insertion port corresponding to the shape of the retaining plate. The retaining plate is inserted into the mounting groove through the insertion port and then rotated to achieve installation and fixation.

[0010] The triggering structure includes a fixed ring fixed inside the gun barrel, a movable ring and an electric push rod on the fixed ring, one end of the movable ring being hinged to the fixed ring and the other end being hinged to the electric push rod; the electric push rod pushes the movable ring closer to the sliding sleeve to trigger the firing base to fire the projectile.

[0011] A knob handle is fixed on the locking plate, and the one-way valve is located in the middle of the knob handle. The knob handle is plate-shaped and its end is inclined to the outside.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] The projectile is equipped with a launch base at its tail and a triggering mechanism inside the breech. The triggering mechanism activates the launch base to fire the projectile. The triggering mechanism is concealed within the gun body, allowing for a more realistic design of the gun's shape. The operation involves loading the projectile and launch base into the breech, triggering the launch base to fire the projectile, and then retracting the launch base from the breech. This includes three steps: loading, firing, and retracting the breech, which better simulates the operation of an artillery piece and provides a better user experience. An inflation device is also included to inflate the projectile. The projectile is loaded first and then inflated, meaning the projectile is loaded uninflated during loading to prevent accidental firing and ensure usability.

[0023] Please refer to Figure 1-3 As shown, this utility model provides a loading and launching structure for a simulated artillery piece; it includes an artillery body 1, a gun barrel 11 mounted on the artillery body 1, a projectile 2 inside the gun barrel 11, a launching base 21 mounted on the tail of the projectile 2, the launching base 21 being detachably snapped into the gun barrel 11, and an excitation structure 3 provided inside the gun barrel 11, the excitation structure 3 being used to trigger the launching base 21 to launch the projectile 2.

[0024] The launching base 21 includes a one-way valve 211 that communicates with the projectile 2. A breech cover 12 is installed at the rear of the gun barrel 11. An inflation device 4 is also provided on the gun body 1. The inflation device 4 includes an inflation head 41 installed inside the breech cover 12. The inflation head 41 is sealed and plugged into the one-way valve 211.

[0025] The launching base 21 includes a ball bearing seat 212, inside which a water supply pipe 213 is provided. The water supply pipe 213 is connected to a one-way valve 211. The ball bearing seat 212 is provided with a plurality of balls 214 for clamping the projectile 2. The ball bearing seat 213 is covered with a sliding sleeve 215 for controlling the movement of the balls 214. The sliding sleeve 215 reciprocates along the ball bearing seat 212 to realize the movement of the balls 214 away from and clamping the projectile 2. Specifically, the launching base 21 can refer to a water rocket launching device for simulating a mortar disclosed in patent number CN201721635721.5.

[0026] The inflation device 4 also includes a water tank, a liquid pump, and an air pump (not shown in the figure). The water tank is connected to the inflation head 41 through the liquid pump and a pipe. The air pump is connected to the inflation head 41 through a pipe. The liquid pump draws water from the water tank and injects it into the inflation head 41. The air pump draws air and delivers it to the inflation head 41. Then, the water and air are injected into the shell 2 through the inflation head 41 via the one-way valve 211 and the water supply pipe 213, forming a high pressure inside the shell 2. It is not necessary to pre-inflate the shell 2 before loading it into the gun barrel, thus avoiding the shell 2 being accidentally bumped and squeezed by the sliding sleeve 215 during loading into the gun barrel 11, which would cause the shell 2 to fire prematurely. Furthermore, to ensure the realism of the shape of the artillery body 1, the water tank, liquid pump, and air pump can be hidden inside the artillery body 1.

[0027] The barrel 11 is provided with a mounting groove 111, and a retaining piece 216 is fixed on the ball bearing seat 212. The retaining piece 216 has multiple protrusions around its perimeter. The mounting groove 111 is provided with an insertion port corresponding to the shape of the retaining piece 216. The retaining piece 216 is inserted into the mounting groove 111 through the insertion port and then rotated to achieve installation and fixation.

[0028] The triggering structure 3 includes a fixed ring 31 fixed inside the gun barrel 11. The fixed ring 31 is provided with a movable ring 32 and an electric push rod 33. One end of the movable ring 32 is hinged to the fixed ring 31, and the other end is hinged to the electric push rod 33. The electric push rod 33 pushes the movable ring 32 close to the sliding sleeve 215 to trigger the firing base 21 to fire the shell 2.

[0029] The cannon body 1 is equipped with a controller, which is electrically connected to the electric push rod 33 and the liquid pump and air pump, and wirelessly connected to the remote control. The controller receives the wireless signal from the remote control to control the start and stop of the electric push rod 33 and the liquid pump and air pump.

[0030] A knob handle 217 is fixed on the locking plate 216, and a one-way valve 211 is located in the middle of the knob handle 217. The knob handle 217 is plate-shaped and its end is inclined to the outside.

[0031] In practice, the user loads the shell 2 into the breech 11, aligns the protrusion on the locking piece 216 with the groove at the loading entrance of the locking slot 111, inserts the locking piece 216 into the locking slot 111, and rotates the locking piece 216 using the knob 217 so that its protrusion is misaligned with the groove at the loading entrance of the locking slot 111, locking it into the locking slot 111. Then, the breech cover 12 is closed, and the inflation head 41 inside the breech cover 12 is connected to the one-way valve 211. At this time, the operator remotely controls the inflation device 4 to inject water and gas into the shell 2 through the inflation head 41 and the one-way valve 211 to form high pressure. At this time, the shell 2 is locked by the ball 214 and will not be fired due to high pressure. After the simulated switch (which is modeled after the actual cannon switch but only functions as a switch and cannot control the firing of the shell) is preset on the cannon body 1, the staff presses the button to activate the electric push rod 33, which pushes the movable ring 32. The movable ring 32 presses the sliding sleeve 215 to slide, causing the ball 214 to move away from the shell 2 and no longer lock the shell 2. The shell 2 is then fired under high pressure. The user then opens the breech cover 12, rotates the knob handle 217, and aligns the locking piece 216 with the groove of the mounting slot 111. The user then removes the locking piece 216 along with the firing base 21 and loads the next shell with the firing base 21 for the next firing experience.

[0032] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
