Description

Bullet for gas injector {A bullet for gas operated shooter}

The present invention relates to a bullet for a gas injector, and in particular, a separate injection compressed gas is contained in a cylinder of a gas injector containing an injection chemical to eject the compressed gas built up by a blow from the rear to inject the chemical in the cylinder. It relates to a bullet for a gas injector to be made.

In general, as a bullet for a launch device for injecting a liquid medicine, a structure of a bullet for a firearm filed in Utility Model Registration No. 5991 in 1996 and registered as Utility Model Registration No. 127511 is known.

In addition, anesthesia guns for firing bullets containing anesthetics were known.

In the latter case, the anesthesia liquid has a built-in needle structure for the syringe, and the anesthesia gun is inserted into the skin of the animal and the liquid is injected at the same time.

In the former case, as illustrated in FIG. 5, a cylindrical cylinder 100, a primer 110 containing a gunpowder that is a predetermined length at the rear end of the cylinder 100, and the inside of the cylinder 100. It consists of a piston (120) for pushing the filled tear liquid and the like, and a cap (130) with a predetermined stopper (140) screwed to the tip opening of the cylinder (100).

Therefore, as the explosive explosion of the primer, the piston moves, the tear fluid is pushed out by the piston movement, and the tear liquid is injected while opening the stopper.

In the case of such a bullet, the piston pushes out the liquid to push it in, but the liquid inside the cylinder must be discharged only by the explosive force of the gunpowder. Therefore, the explosive structure and the explosive force treatment structure must be provided. It is no longer possible to use gas guns with bullets.

Therefore, there has been a demand for a chemical injection gas injector that does not use gunpowder, and in particular, a bullet structure for a gas injector capable of producing an explosive sound of the gunpowder is required.

In view of this, the present invention provides a bullet structure for completely ejecting the desired ejection agent as a bullet for a gas injector without residue, and in particular, the ejection structure of such an agent does not depend on the explosive power of the gunpowder and is self-accepted compression. It aims to provide a bullet structure made possible by gas, and to provide a bullet for a gas injector in which the explosion of the gunpowder only utters sound.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention covers the cylinder 200, the piston 300, and the back of the cylinder 200, while having a predetermined compressed gas ejection structure to the gas working part 400 for pushing the piston 300 Are distinguished.

The cylinder 200 forms an injection hole 204, which is opened and closed by a stopper 210 at the front end thereof, and the rear end forms an open cylinder having a screw 202 formed therein.

The piston 300 is located in the drug receiving space 202 of the cylinder 200 and pushes the medicine forward at a predetermined pressure. The flange 302 of the piston 300 is mounted with a rubber ring 310 having a hole 312.

The gas working part 400 for pushing the piston 300 while covering the rear of the cylinder 200 behind the piston 300 is again a gas receptor 410, a cover body 420, and a rear cover 430. ) And the striking member 440.

The gas receptor 410 is a cylindrical body in which the rear side is opened and the tip forms the gas injection hole 411. The rear inner peripheral surface of the gas receptor 410 is provided with a screw 412.

The cover body 420 for sealing the rear of the gas receptor 410 is formed at the rear end of the blow film 421 cut by a predetermined gas strike and the outer periphery of the protruding frame 425 and the screw 423 ( 424) are cylindrical bodies each formed.

The gas receptor 410 and the cover 420 is screwed into the opening facing each other opening.

When the gas receptor 410 is coupled to the cover 420, first, the spring 426, the metal ball 427, the washer 428, and the O-ring 429 are sequentially inserted into the gas filling chamber 422 of the cover 420. The cover body 420 containing the screw is screwed to the gas receptor 410. That is, the screw 412 and the screw 424 are screwed to the boundary of the protruding frame 425 of the cover body 420.

The combined structure of the gas receptor 410 and the cover body 420 eventually forms a gas receiving means so that when the compressed gas injection hole prepared in the gas injection hole 411 is pushed separately, the metal ball 427 is pressed and filled. The metal ball 427 is sealed by blocking the injection hole 411 in the filled state. When a predetermined pressure strikes the blow film 421 in this state, the blow film 421 is cut off, and the compressed gas is blown out through the cutout.

The present invention can also be implemented as a closed gas cylinder consisting of the gas receptor 410 and the cover body 420 as one.

In addition, the rear cover 430 is coupled to the remaining screw 423 side of the cover body 420.

That is, the rear cover 430 forms a blow hole 432 at the end side blocking the rear of the cylindrical body, the front is an open cylindrical body, and forms an outlet hole 434 on one side of the cylindrical main surface. The outflow hole 434 forms an outflow path of the compressed gas by the gas receptor 410 and the cover body 420.

The inner space 433 of the rear cover 430 has a built-in striking member 440 to move back and forth by a predetermined striking pressure. The striking member 440 protrudes the striking protrusion 442 and the cutting protrusion 444 of short diameter, respectively, at the front and rear ends of the disc shape, and an insertion groove into which the rubber ring 441 is inserted into the periphery of the disc shape. 443).

The rear cover 430 is screwed with the screw 423 of the cover body 420 through a screw 431 formed in the opening.

The striking member 440 is embedded before screwing the rear cover 430 and the cover body 420 as described above.

The present invention of such a configuration maintains the engagement cross-sectional state as shown in Figure 3a. Then, when a predetermined striking pressure is applied to the rear of the cylinder 200, the predetermined medicine contained in the cylinder 200 is ejected by acting as shown in FIG. 3B.

That is, when the blow hole of the gas injector is hit by the blow protrusion 442 of the blow member 440 located in the blow hole 432 of the rear cover 430, the blow member 440 is teleported to cover the cut protrusion 443. The striking film 421 of the sieve 420 is cut off. At this moment, the compressed gas filled with the cover body 420 and the gas receptor 410 is pushed out. The compressed gas moves through the gas passage a through the outlet hole 434 and at the same time the piston 300 Pushed). As the piston 300 pushes the medicine contained in the cylinder 200 with a strong pressure, the gusset 210 of the tip of the cylinder 200 is separated and the medicine is ejected at the same time.

In particular, the present invention is characterized by not using the explosive force of the gunpowder because the operation to cut the blow film 421 of the cover body 420 as described above is made by the blow hole of the gas injector.

However, even without using the explosive power of the gunpowder can produce a sound that is generated when the explosive is exploded. That is, when the bullet with the gunpowder 500 is mounted in the inner space 433 of the rear cover 430 as shown in FIG. 421). Therefore, while providing a vocal effect, such as explosive explosives, it provides a gas ejector bullet for ejecting the drug.

As such, the present invention improves the problem of the explosives of the gas injector bullet, which injects the conventional chemicals into the explosive force of the gunpowder, thereby providing a bullet structure that ejects the medicine with the compressed gas accommodated at the same time as the blow with the simple blow device. .

Such a compressed gas ejection type chemical injection structure provides a relatively safe chemical injection bullet without the need to change the structure required for explosives.
