Abstract

The invention discloses a prop gun and a method for safely using the prop gun, and belongs to the technical field of prop guns. The prop gun is loaded with a real bullet, so that death and injury caused by fire escape can not occur any more. The invention adopts 3 modes: the first is to use only the bent tube, the second is to use only the folded tube, and the third is to combine the bent tube and the folded tube together to form the gun barrel with the inside of a labyrinth structure. The labyrinth structure can lead the gunpowder gas to be discharged from the chamber, and the bullet is lost in the labyrinth. The gunpowder gas which is sprayed out from the muzzle and does not burn fully meets oxygen in the air, and continues burning to form muzzle flame which is more vivid. The inner diameter of the gun barrel is smaller than the caliber of the bullet of the real gun, and the bullet of the real gun cannot be shot out of the gun port. The bullet can not go out of the muzzle, so that the bullet is safer. Tesla valve: the air flow of the curved arrow can slow down the air flow speed of the straight arrow, so that the explosive gas discharging speed is reduced, the explosive gas discharging speed is slow, the discharging speed of the bullet is slow, and the bullet is not powerful when the bullet is continuously shot in multiple times.

Description

Safety life-like prop gun

Technical Field

The invention discloses a prop gun and a method for safely using the prop gun, and belongs to the technical field of prop guns.

Background

Publication No. CN213555371U, title of the invention: the gun with the empty-bag film and video prop has a solid barrel structure, is safe, does not have muzzle flame, needs special effect in later period to increase the muzzle flame, and is not vivid.

Publication No. CN2171842Y, title of the invention: the novel safety prop gun is fixed by pins and can ventilate the blocking device, and the flame at the muzzle can be penetrated out. Compared with the scheme of the invention which only adopts a thin tube, the structure of the invention is more complex.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the problems, the safe prop gun and the method for safely using the prop gun are provided to solve the defects, and when the prop gun is used for shooting, safety and reality are both considered.

In order to achieve the purpose, the technical scheme of the invention is as follows:

adopt 3 kinds of modes: the first is to use only the bent tube, the second is to use only the folded tube, and the third is to combine the bent tube and the folded tube together to form the gun barrel with the inside of a labyrinth structure. The labyrinth structure can lead the gunpowder gas to be discharged from the chamber, and the bullet is lost in the labyrinth. The gunpowder gas which is sprayed out from the gun mouth and does not burn fully meets oxygen in the air, and continues burning to form gun mouth flame which is more vivid.

The inner diameter of the gun barrel is smaller than the caliber of the bullet of the real gun, and the bullet of the real gun cannot shoot out of the gun mouth. When shooting, the complete real gun bullet can not be ejected from the muzzle, and accidents can not be caused.

The technical scheme is summarized as a word: the technical scheme of the invention is 'dredging'.

The first generation of the invention prevents the ejection of the bullet heads by designing: the barrel of the gun is small in pipe, when a 9 mm bullet is used in a real gun, a section of the pipe of the gun barrel, which is close to the gun chamber, of the gun barrel adopts a thin pipe, for example, the inner diameter of the thin pipe is only 3 mm, and the bullet head of the 9 mm bullet cannot be shot. The diameter of the gun barrel close to the muzzle can be as large as that of a real gun so as to avoid influencing the shooting effect.

Hidden danger of first generation design: if the bullet uses a "sub-caliber bullet", for example, the bullet is a needle bullet with a diameter of 2 mm, a sub-caliber armor piercing bullet similar to a tank, or can be ejected from a straight barrel with an inner diameter of 3 mm.

The second generation design: the inner structure of the gun barrel is an S-shaped pipe. The S-shaped pipe is bent to an opening at one end of the gun chamber and an opening at one end of the gun mouth, and the sight of eyes cannot pass through the S-shaped pipe. A straight, needle-like rigid bullet of sufficient strength that it is impossible to eject it from the S-shaped channel.

Hidden danger of the second generation design: if the bullet is a spherical bullet, it can be ejected from a barrel with an S-shaped inner wall, similar to the spherical bullet used in earlier firearms.

And (3) third generation design: the shape of the barrel tube, with the shape of the "map of great wall marker", replaces the S-shape.

Hidden danger of third generation design: the spherical bullet may not be shot out of the bore; the gun barrel can also be shot out of the gun chamber because the gun barrel is always pushed by gunpowder gas, but the speed is reduced once the spherical bullet collides with the inner wall of the gun barrel, so that the speed is greatly reduced even if the gun barrel is shot out of the gun chamber.

Fourth-generation design: close to one side of muzzle, the corner of barrel, the inner tube extension is one section, produces the dead catch that a warhead entered and hardly comes out, forms "warhead trap", and the ball-type warhead that gets into "warhead trap" is hardly come out, just also is difficult to go out the thorax.

Hidden danger of fourth generation design: the number of warheads which can be trapped by the warhead trap is limited, and when a bullet has a plurality of spherical warheads and the number of warheads is more than the number of warheads which can be trapped by the warhead trap, the warheads can be discharged from the chamber. When shooting continuously, a plurality of spherical warheads of a plurality of bullets can be discharged from the chamber sooner or later.

Designing in the fifth generation: the barrel pipe is connected with a series of Z-shaped and reverse Z-shaped pipes, and the effect of preventing the bullet from leaving the chamber is better than that of a map mark of a great wall; the bullet trap can be used in combination or not.

Hidden danger of fifth generation design: after the gunpowder gas is ejected from the muzzle, the air pressure inside the gun barrel is reduced, the different surfaces of the spherical bullet have pressure difference, and the spherical bullet may move inside the gun barrel, at this time, if the next bullet is fired, the bullet of the next bullet compresses the gas in the gun barrel, and the bullet of the previous bullet still may be discharged, although the discharging speed is slow.

Design of the sixth generation: the 'Tesla valve' plus the barrel of the 'bullet trap' is adopted, and the 'bullet trap' can be omitted. The bore discharge speed of the propellant powder gas is reduced to be lower, and even if the bullet is discharged from the bore, the bullet has little power because the bore discharge speed is too low.

The various combinations of the inner tube shapes are not exhaustive and are not listed.

The single head (only one warhead) of the shotgun unlocks the bullet, and after the door lock is shot, the only warhead can be broken into powder, so that the warhead is prevented from rebounding to cause killing. The single-head unlocking bullet is made of metal powder into a bullet by a special process, obviously, if a large amount of metal powder is sprayed on a door lock, the door lock has no door opening effect, and the speed of the powdered metal is attenuated too fast in the air.

The safe use method of the prop gun comprises the following steps: 1. before each use, a fireman of a play group checks a prop gun and an empty package bullet by using instruments such as a metal flaw detector and the like when using actors and a director of the prop gun; the props are prevented from being unpacked by people, for example, the gun barrel of the props is changed into a real gun barrel, a blank packed bullet is changed into a real bullet, or the props are disguised as blank packed bullets and have bullets in the actual inner parts; after the check, the gunner, the actor and the director sign in turn. 2. When a play group shoots a gun battlefield, workers such as actors, cameramen, directors and the like wear the body armor as much as possible; the soft bulletproof garment with the bulletproof plugboard is not needed to be inserted, and playing and shooting are basically not affected; most of the time, only the front half part can be worn; unless a prop gun is required for shooting and the gun is fired at the back of the actor, the back is required to have a body armor.

Due to the adoption of the structure, the invention has the beneficial effects of safety and vividness.

Detailed Description

As shown in fig. 1, the shaded portion is a solid portion of the barrel. When the diameter of the bullet is much larger than that of the thin tube, for example, the bullet with the less deformable outer diameter of 9.02 mm of a 9 mm bullet cannot be shot from a barrel with the inner diameter of 3 mm. 3 mm is only one, but not the only one, of a number of selectable inner diameter diameters, and specific numbers are not listed.

As shown in fig. 2, when the barrel tube is shaped as a great wall geodesic, the spherical bullet may not be discharged; even if it is possible to discharge, the speed is certainly slower than that of a straight inner tube or an S-shaped inner tube.

As shown in fig. 3, the ball bullet is more difficult to get out of the chamber after entering the bullet trap.

As shown in fig. 4, the shaded portion is a solid portion of the barrel. The two circles are spherical warheads that sink into the warhead trap. The trap may trap one or several warheads.

As shown in fig. 5, the barrel channel is formed in a series of "Z" shapes joined by an inverted "Z" shape, which makes it more difficult to fire the round bullet than if the barrel channel were formed as a great wall map.

As shown in fig. 6, the barrel conduit is designed with a "tesla valve" plus "bullet trap". Tesla valve: the air flow of the bent arrow head can slow down the air flow speed of the straight arrow head, so that the chamber outlet speed of gunpowder gas is reduced, the chamber outlet speed of the gunpowder gas is slow, the chamber outlet speed of the bullet is slow, and the bullet does not have power when shooting continuously and frequently.

The labyrinth structure of the single part is too difficult to machine and a tiger-like design can be used. The tiger symbol is formed by combining two detachable parts, and the parts are tightly screwed together. For long-term use, the interior of the gun barrel is dirty; split into two pieces, is convenient for clean the gun barrel.
