Description

Technical Field

[0001] The present invention relates to the field of machinery, and more particularly to the field of mechanical components, and specifically to a prop gun and its usage method. Background Art

[0002] There are numerous film crews in the film and television industry in our country, and there are also many war-themed dramas. War-themed dramas usually need to be equipped with props such as guns and cannons to restore war scenes. Currently, there are mainly two types of film and television prop guns: the first type is to use real guns, but without installing bullets, and only blank cartridges are fired; the second type is an externally simulated gun without a firing device, which only appears on camera during the performance and does not need to be fired. Among them, real guns are very strictly managed due to their killing ability, and the application procedures are very difficult, so general film crews are deterred. Although externally simulated guns are safe, they only look like real guns, and the film and television effects are poor. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a prop gun and its usage method, which can generate fire and explosion sounds, thus playing the role of replacing real guns.

[0004] The present invention is realized through the following technical solutions. A prop gun includes a gas supply device located inside the gun body for supplying combustible gas, a combustion chamber communicated with the barrel, and an intake pipe connecting the gas supply device and the combustion chamber. A valve structure that blocks the intake pipe and cooperates with the trigger is provided on the intake pipe. An igniter is also provided inside the combustion chamber. An ignition switch electrically connected to the igniter and arranged on the trigger is also provided inside the gun body. A limiting structure cooperating with the ignition switch is also provided inside the gun body. The time point when the cooperation between the trigger and the valve ends is the time point when the limiting structure triggers the ignition switch.

[0005] When the present invention is in use, the gas supply device flushes combustible gas into the valve. Pull the trigger, and the trigger opens the valve, making the intake pipe unobstructed, so that the gas in the gas supply device enters the combustion chamber. Continue to turn the trigger. At this time, the valve structure blocks the intake pipe, and at the same time, the limiting mechanism triggers the ignition switch. The igniter ignites the combustible gas in the combustion chamber. After the gas is ignited, an explosion sound and a fire light are emitted from the barrel, thus playing the role of replacing real guns and enhancing the film and television effects; at the same time, since the intake pipe is blocked, it plays a role in protecting the gas supply device.

[0006] Preferably, the gas supply device includes a pressure tank located inside the gun body. The pressure tank is filled with combustible gas and oxygen. The pressure tank is communicated with a mixing valve, and the mixing valve is communicated with the intake pipe.

[0007] When this preferred solution is in use, flammable gas and oxygen are directly filled into the pressure tank, so that there is a tank body inside the gun body, saving the space occupied by the gun body. Secondly, because it is a pressure tank, the mixed gas can directly enter the valve structure. At the same time, when the valve structure is opened, the mixed gas can directly enter the combustion chamber.

[0008] Preferably, the intake pipe includes a second air pipe communicating with the combustion chamber and a first air pipe communicating with the gas supply device. The valve structure includes a first air chamber with an air inlet communicating with the first air pipe and a second air chamber with an air outlet communicating with the second air pipe. A sliding rod is hermetically slidably connected in the first air chamber and the second air chamber. The trigger pushes the sliding rod through a connecting structure to block the air inlet of the first air chamber. A cavity is formed in the sliding rod, and a first opening and a second opening communicating with the cavity and located in the first air chamber and the second air chamber respectively are formed on the sliding rod. The first opening is located in the side wall of the first air chamber, and the second opening is located in the inner cavity of the second air chamber. The maximum moving distance of the second opening is adapted to the maximum moving distance of the sliding rod. The diameter of the first opening is smaller than the thickness of the side wall of the first air chamber, and the diameter of the second opening is smaller than the thickness of the side wall of the second air chamber.

[0009] When this preferred solution is in use, the mixed gas enters the first air chamber, pushes the sliding rod to slide, and makes the first air hole located in the side wall of the first air chamber, so that the side wall of the first air chamber blocks the first air hole. When the trigger is pulled, the sliding rod is driven to move towards the air inlet through the connecting structure. At this time, the first perforation moves into the inner cavity of the first air chamber. Under the action of pressure, the mixed gas enters the second air chamber along the cavity of the sliding rod, and enters the combustion chamber through the air outlet and the second air pipe, so as to realize the entry of the mixed gas into the combustion chamber. At the same time, the trigger continues to rotate, and the connecting structure drives the sliding rod to top on the air inlet, thus blocking the air inlet. At the same time, the second air hole enters the side wall of the second air chamber, thus forming two blockades, so as to play a role in protecting the flammable gas tank and the oxygen tank and ensuring the installation of the gun body.

[0010] Preferably, the arrangement direction of the first air chamber and the second air chamber is parallel to the extending direction of the sliding rod. An air inlet is formed on the side wall of the first air chamber away from the second air chamber, and a first sealing ring for the sliding rod to penetrate through hermetically is arranged on the side wall of the first air chamber opposite to the air inlet. A second sealing ring is arranged on the side wall of the second air chamber close to the first air chamber. The sliding rod sequentially penetrates through the second sealing ring and the first sealing ring. The thickness of the first sealing ring is greater than the diameter of the first perforation, and the thickness of the second sealing ring is greater than the diameter of the second perforation.

[0011] Through the arrangement of the second sealing ring and the first sealing ring in this preferred solution, it is ensured that when the first air hole is located in the side wall of the first air chamber and the second air hole is located in the second side wall, the first air hole and the second air hole are blocked.

[0012] Preferably, a sleeve located in the inner cavity of the second air chamber is also fixedly connected to the sliding rod. The outer diameter of one end of the sleeve close to the second sealing ring is smaller than that of the other end of the sleeve, and the opening diameter of the second sealing ring is smaller than the outer diameter of the other end of the sleeve. A sleeve located in the inner cavity of the first air chamber is also fixedly connected to the sliding rod. The outer diameter of one end of the sleeve close to the first sealing ring is smaller than that of the other end of the sleeve, and the opening diameter of the first sealing ring is smaller than the outer diameter of the other end of the sleeve. A sealing pad is provided at one end of the sliding rod for blocking the air inlet.

[0013] In this preferred solution, since the outer circumferential surface of the sleeve is a conical surface inclined towards the first sealing ring or the second sealing ring, when the sliding rod moves, it plays a role in blocking the first sealing ring or the second sealing ring, making the sealing effect between the first sealing ring and the sliding rod and between the second sealing ring and the sliding rod better, thereby further improving safety.

[0014] Preferably, the connecting structure includes a limiting rod fixedly connected to the end of the sliding rod away from the air inlet and sealingly extending out of the second air chamber. The limiting rod is slidably and sealingly connected to the side wall of the second air chamber. A limiting plate is fixedly connected to the limiting rod, and the limiting plate extends into the rotation path of the trigger.

[0015] In this preferred solution, the transmission between the trigger and the sliding rod is realized through the arrangement of the limiting plate and the limiting rod.

[0016] Preferably, a spring is also sleeved on the limiting rod, and the two ends of the spring are respectively abutted against the limiting plate and the first air chamber.

[0017] In this preferred solution, through the arrangement of the spring, it is convenient to position the limiting plate and the trigger.

[0018] Preferably, the trigger is hinged to the gun body through a hinge shaft. A U-shaped block located above the hinge shaft is fixedly connected to the top end of the trigger. The limiting plate is located in the rotation path of the U-shaped block. In the use of this preferred solution, when the U-shaped block pushes the valve core, a part of the valve core passes through the center of the U-shaped block. Using the U-shaped block saves space, makes the overall structure more compact, and has better adaptability.

[0019] Preferably, the ignition switch is fixedly connected to the trigger, and an elastic strip is fixedly connected to the gun body and extends into the rotation path of the ignition switch.

[0020] In this preferred solution, the elastic strip is an M3 nylon screw. The advantages of the nylon screw are that it has insulation to avoid accidental short circuits. At the same time, the nylon screw has elasticity and wear resistance, preventing hard contact from damaging the ignition switch; preventing wear during long-term use, and at the same time, the distance can be adjusted through the screw to select the appropriate ignition timing.

[0021] A method for using a prop gun includes the following steps.

[0022] a. Combustible gas and oxygen are mixed and then charged into the pressure tank, and a certain pressure is maintained. The mixed gas enters the first air chamber through the gas mixing valve and the first air pipe. Due to the setting of the pressure tank, the mixed gas enters the first air chamber under the action of pressure. At this time, the first perforation is located within the first sealing ring;

[0023] b. Pull the trigger. The trigger rotates clockwise, the U-shaped block rotates clockwise, the slide rod passes through the perforation of the U-shaped block, and the U-shaped block is pushed against the limit plate;

[0024] c. The U-shaped block pushes the limit plate to move along the extension direction of the slide rod. At the same time, the limit plate compresses the spring, and the limit plate drives the slide rod to slide through the limit rod;

[0025] d. The slide rod slides forward. At this time, the first perforation moves into the inner cavity of the first air chamber. The mixed gas enters the second air chamber along the cavity of the slide rod under the action of pressure, and enters the combustion chamber through the air outlet and the second air pipe;

[0026] e. As the trigger continues to rotate, when the trigger rotates to the final position, the end of the slide rod close to the air inlet is pushed against the air inlet, thus blocking the air inlet. At the same time, the second perforation enters within the second sealing ring and is blocked by the second sealing ring. The front end of the sleeve within the second air chamber is inserted into the second sealing ring;

[0027] f. At the same time, when the trigger continues to rotate, the ignition switch is pushed against the elastic strip as the trigger rotates, deforming the elastic strip. As the trigger continues to rotate, the deformation of the elastic strip increases. When the trigger rotates to the final position, the elastic strip triggers the ignition switch, and the ignition switch ignites the mixed gas within the combustion chamber, causing the mixed gas to explode, generating a fire and an explosion sound, thus serving as a substitute for a real gun;

[0028] g. At the same time, when the trigger is not pulled, the slide rod and the trigger reset under the action of the spring, and the mixed gas re-enters the first air chamber again, facilitating the next firing.

[0029] The beneficial effects of the present invention are as follows: The gas supply device charges combustible gas into the valve. Pull the trigger, and the trigger opens the valve, making the air inlet pipe unobstructed, so that the gas within the gas supply device enters the combustion chamber. Continue to rotate the trigger. At this time, the valve structure blocks the air inlet pipe. At the same time, the limit mechanism triggers the ignition switch, and the igniter ignites the combustible gas within the combustion chamber. After the gas is ignited, an explosion sound and a fire are emitted from the barrel, thus serving as a substitute for a real gun and enhancing the film and television effect; at the same time, since the air inlet pipe is blocked, it plays a role in protecting the gas supply device; through the settings of the sleeve and the slide rod blocking the air inlet and the second perforation being located within the second sealing ring, the passage for the mixed gas to enter the combustion chamber is blocked, thus ensuring the safety of the gun body during use.

A limiting plate 5 is fixedly connected to the limiting rod 15, and the limiting plate 5 extends to the rotation path of the trigger 7.

[0047] A spring 16 is also sleeved on the limiting rod 15, and the two ends of the spring 16 respectively abut against the limiting plate 5 and the first air chamber 1.

[0048] The trigger 7 is hinged to the gun body through a hinge shaft. A U-shaped block 10 is fixedly connected to the top end of the trigger 7 and located above the hinge shaft. The limiting plate 5 is located on the rotation path of the U-shaped block 10, and the sliding rod 17 penetrates through the U-shaped block 10.

[0049] An ignition switch 8 electrically connected to the igniter is also fixedly connected to the trigger 7. An elastic strip 9 is fixedly connected to the gun body, and the elastic strip 9 extends to the rotation path of the ignition switch 8. The ignition switch 8 is a push-button switch, and the elastic strip is an M3 nylon screw.

[0050] The using method of the prop gun includes the following steps:

[0051] a. The combustible gas and oxygen are mixed and then flushed into the pressure tank 19 and maintained at a certain pressure. The mixed gas enters the first air chamber 1 through the mixing valve 20 and the first air pipe 12. Due to the setting of the pressure tank 19, the mixed gas enters the first air chamber 1 under the action of pressure. At this time, the first perforation is located within the first sealing ring 11, and the second perforation is located in the inner cavity of the second air chamber 2.

[0052] b. Pull the trigger 7, the trigger 7 rotates clockwise, the U-shaped block 10 rotates clockwise, the sliding rod 17 passes through the perforation of the U-shaped block 10, and the U-shaped block 10 abuts against the limiting plate 5.

[0053] c. The U-shaped block 10 pushes the limiting plate 5 to move along the extending direction of the sliding rod 17. At the same time, the limiting plate 5 compresses the spring 16, and the limiting plate 5 drives the sliding rod 17 to slide through the limiting rod 15.

[0056] f. At the same time, when the trigger 7 continues to rotate, the ignition switch 8 rotates with the trigger 7 and abuts on the elastic strip 9, deforming the elastic strip 9. As the trigger 7 continues to rotate, the deformation amount of the elastic strip 9 increases. When the trigger 7 rotates to the final position, the elastic strip 9 triggers the ignition switch 8, and the ignition switch 8 causes the igniter to ignite the mixed gas in the combustion chamber 4, so that the mixed gas explodes, generating a fire and an explosion sound, thus acting as a substitute for a real gun;

[0057] g. At the same time, when the trigger 7 is not pulled, under the action of the spring 16, the slide bar 17 and the trigger 7 reset, and the mixed gas re-enters the first air chamber 1 again, thus facilitating the next firing.
