Description

Technical Field

[0001] This utility model relates to the field of simulated gun technology, and in particular to a safe firing and sound-emitting device for prop guns used in film and television. Background Technology

[0002] In film and television shooting, stage performances and other scenarios, prop guns are important tools for creating plot conflicts and creating a tense atmosphere. Among them, dramas involving gunfights, military, police and gangster plots have increasingly strict requirements for the authenticity and professionalism of props. As an indispensable key prop in such works, the performance and presentation of simulated guns directly affect the quality of the film and the audience's sense of immersion.

[0003] In gunfight movies, an electric spark ignites a combustible mixture in a combustion chamber to achieve the effect of a real gun being fired, producing smoke and sound at the muzzle, and this effect can be repeated multiple times.

[0004] Existing prop gun safety firing and sound-generating devices for film and television productions only achieve a single explosion effect during use, with no smoke emanating from the muzzle. This requires tedious editing to achieve the desired effect. Furthermore, connecting the various gas cylinders requires multiple twists of the connectors, lacking a function for quickly connecting the gas pipes to the pipeline. Therefore, a new prop gun safety firing and sound-generating device for film and television productions is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0025] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a safe firing and sound-emitting device for a prop gun used in film and television dramas, including a gun shell 1, a combustion and explosion mechanism 2 disposed inside the gun shell 1, and a locking mechanism 3 disposed inside the combustion and explosion mechanism 2.

[0026] The combustion and explosion mechanism 2 includes an oxygen cylinder 203 disposed inside the gun housing 1, a butane cylinder 204 disposed on one side of the oxygen cylinder 203, a gas pressure regulating valve 202 adapted to the butane cylinder 204 installed inside the gun housing 1, a circuit board 201 disposed inside the inner cavity of the gun housing 1, a combustion and explosion chamber 207 disposed on the front side inside the gun housing 1, and a first solenoid valve 205, a current converter 208, a second solenoid valve 209 and a third solenoid valve 210 disposed on one side of the combustion and explosion chamber 207.

[0027] Specifically, the gas pressure regulating valve 202 is connected to the second solenoid valve 209 and the third solenoid valve 210 via pipes. The oxygen cylinder 203 is connected to the first solenoid valve 205 via pipes. The circuit board 201 is electrically connected to the first solenoid valve 205, the current converter 208, and the second solenoid valve 209 via wiring harnesses. The third solenoid valve 210 is electrically connected to the circuit board 201 via wiring harnesses. The combustion chamber 207 is connected to the first solenoid valve 205, the current converter 208, the second solenoid valve 209, and the third solenoid valve 210 via pipes. The gas pressure regulating valve 202 is connected to the butane cylinder 204 via pipes. Under the action of the gas pressure regulating valve 202, the stability of the gas emitted from the butane cylinder 204 is controlled to prevent accidents. The control of the first solenoid valve 205, the current converter 208, the second solenoid valve 209, and the third solenoid valve 210 by the circuit board 201 ensures that the gas discharged into the combustion chamber 207 is balanced, sufficient for a single combustion explosion, and has a certain degree of safety.

[0028] Specifically, the gun casing 1 is equipped with a battery 213, a third solenoid valve 210 adapted to the circuit board 201, a power switch 212 and a trigger 211, and a barrel 206 adapted to the combustion chamber 207 is installed on one side of the gun casing 1. Under the action of the battery 213, a certain amount of power is provided to the circuit board 201, and the timing of the combustion explosion is controlled by pulling the trigger 211.

[0029] Specifically, the battery 213 is electrically connected to the circuit board 201 via a wiring harness, and the power switch 212 is connected to a wiring harness. The trigger 211 is electrically connected to the circuit board 201 via a wiring harness. Under the action of the power switch 212, the current input to the circuit board 201 can be disconnected, so that when the battery 213 is not in use, excessive discharge is prevented, which would affect the next use.

[0030] Further, manually turn on the power switch 212 to transmit the energy from the battery 213 to the circuit board 201 via the wiring harness. Install both the oxygen cylinder 203 and the butane cylinder 204 into the gun housing 1 and connect the corresponding pipes. The butane cylinder 204 discharges gas to the gas pressure regulating valve 202, which then sends the gas to the second solenoid valve 209 and the third solenoid valve 210. The second solenoid valve 209 and the third solenoid valve 210 then send the gas through pipes to the combustion chamber 207. The oxygen cylinder 203... 03. Gas is delivered to the first solenoid valve 205 through a pipeline. After passing through the first solenoid valve 205, the gas is delivered to the combustion chamber 207 through a pipeline. At this time, the two gases are mixed. The trigger 211 is manually pulled to issue a command to the circuit board 201. The circuit board 201 controls the operation of the first solenoid valve 205, the current converter 208, the second solenoid valve 209, and the third solenoid valve 210 through the wiring harness to ignite the mixed gas in the combustion chamber 207. The resulting smoke is discharged from the barrel 206. Example

[0031] Reference Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The snap-fit ​​mechanism 3 includes a connecting pipe 302 disposed on one side of the oxygen cylinder 203. A second flange 305 is installed at the output end of the oxygen cylinder 203. A first flange 303 adapted to the second flange 305 is disposed on one side of the connecting pipe 302. A sealing gasket 306 is disposed on the opposite side of the first flange 303 and the second flange 305.

[0032] Specifically, the second flange 305 has a sealing groove on the opposite side of the first flange 303 that is adapted to the sealing gasket 306. The sealing gasket 306 is adapted to the sealing groove of the second flange 305 and the sealing gasket 306. Because there is a certain pressure inside the oxygen cylinder 203, after the first flange 303 is tightly attached to the side of the second flange 305, the sealing gasket 306 prevents air leakage at the joint between the second flange 305 and the first flange 303, thus ensuring the normal operation of the combustion and explosion.

[0033] Specifically, a snap ring 301 is fitted on the outer surface of the oxygen cylinder 203, and a snap block 304 adapted to the snap ring 301 is installed on the outer surface of the first flange 303. Snap blocks 307 are symmetrically arranged on the inner surface of the snap block 304. L-shaped grooves adapted to the snap block 304 are distributed circumferentially on the outer surface of the snap ring 301. A slot adapted to the snap block 307 is opened at the top of the L-shaped groove. After the snap block 304 is pushed into the L-shaped groove of the snap ring 301, a rotational force is applied to the snap block 304 to snap the two snap blocks 307 into the corresponding slots, thus fixing the snap block 304.

[0034] Furthermore, the two snap-fit ​​blocks 304 are placed vertically. The oxygen cylinder 203 drives the second flange 305 to move from left to right from the relative center of the two snap-fit ​​blocks 304, so that the center of the connecting pipe 302 and the center of the oxygen cylinder 203 are at the same level. The sealing gasket 306 is placed on the opposite side of the second flange 305 and the first flange 303. The snap-fit ​​blocks 304 are snapped into the corresponding L-shaped grooves in the snap-fit ​​ring 301. The first flange 303 is rotated, which drives the snap-fit ​​blocks 304 to rotate. The snap-fit ​​blocks 304 drive the corresponding two snap-fit ​​blocks 307 to rotate. Under the action of the two snap-fit ​​blocks 307, the two snap-fit ​​blocks 307 are snapped into the corresponding slots in the L-shaped grooves. After both snap-fit ​​blocks 304 are rotated and fixed, the connection between the second flange 305 and the connecting pipe 302 is completed.

[0035] Working principle: When the film crew needs to use firearms during filming, first, place the two locking blocks 304 vertically. The oxygen cylinder 203 drives the second flange 305 to move from left to right from the relative center of the two locking blocks 304, so that the connecting pipe 302 and the center of the oxygen cylinder 203 are at the same level. Place the sealing gasket 306 on the opposite side of the second flange 305 and the first flange 303, and then lock the locking blocks 304 into the corresponding L-shaped grooves in the locking ring 301. Rotate the first flange 303, and the first flange 303 will drive the locking blocks... When block 304 rotates, the locking block 304 drives the two corresponding locking blocks 307 to rotate. Under the action of the two locking blocks 307, the two locking blocks 307 are engaged into the corresponding L-shaped grooves. After both locking blocks 304 are rotated and fixed, the connection between the second flange 305 and the connecting pipe 302 is completed. The butane bottle 204 can also be connected to the corresponding pipe using the above method. After the oxygen bottle 203 and the butane bottle 204 are connected, the oxygen bottle 203 and the butane bottle 204 are installed into the inner cavity of the gun housing 1, and then manually... The power switch 212 is turned on, and the energy from the battery 213 is transmitted to the circuit board 201 via the wiring harness. The oxygen cylinder 203 and butane cylinder 204 are both installed into the gun housing 1, and their corresponding pipes are connected. The butane cylinder 204 discharges gas to the gas pressure regulating valve 202. The gas pressure regulating valve 202 has a conventional structure, identical to existing publicly disclosed designs. The gas pressure regulating valve 202 sends gas to the second solenoid valve 209 and the third solenoid valve 210. The second solenoid valve 209 and the third solenoid valve 210 then send the gas to the combustion chamber via pipes. In the explosion chamber 207, oxygen cylinder 203 sends gas through a pipeline to the first solenoid valve 205. After passing through the first solenoid valve 205, the gas is sent through a pipeline to the combustion chamber 207. At this time, the two gases are mixed. Manually pulling the trigger 211 applies a command to the circuit board 201. The circuit board 201 controls the operation of the first solenoid valve 205, the current converter 208, the second solenoid valve 209, and the third solenoid valve 210 through the wiring harness, which ignites the mixed gas in the combustion chamber 207. The resulting smoke is discharged from the barrel 206.
