Grenade structure

The present invention relates to a grenade structure, in particular to a grenade body made of a foam material, and the grenade body is automatically exploded when it is shot at a high speed, so that the BB bomb stored inside the projectile is in a flared manner. Target person.

The game that imitates war has lasted for a long time. The reason is that in the gun battle game, people can satisfy the stimulating and passive driving purposes.

The current common survival game is mainly through wearing camouflage clothing, carrying firearms that can be used to fire BB bombs or paintballs for shooting games, and in the process of dodging and chasing, it is like visiting the war scene.

Currently, field games use BB or paintball toy guns, all using pressurized air as the power source. The same gun grenade firing is also operated by the air pressure system inside the transmitter.

The working principle of the general grenade is to set up a gas storage cylinder and a plurality of storage cylinders for pre-storing high-pressure gas inside the projectile. When the grenade launcher triggers the projectile, the valve of the gas-storage cylinder is opened and the high-pressure gas is released. Most of the BB bombs or paintballs are sprayed out instantly. For example, the patent case of Taiwan Patent No. M284872 "BB bomb/painted grenade with high pressure gas continuous pressure structure" or the patent case of "Grenade structure of toy gun" of M422666.

However, as shown in Figure 1, the grenade 100 has a smooth surface and uses high-pressure gas to push the BB projectile. It is easy to fail due to insufficient high-pressure gas tightness or insufficient pressure, and the structure is complicated and costly. High, poor market competitiveness, and the device that requires the gas pressure of the grenade itself, such as a high-pressure gas cylinder. The cylinder must be hard and compact in order to load the high pressure. In addition to increasing the flight load, it is also due to its mass relationship. Incorporating Newton's law of motion, the force of the impact when hitting the target after firing is very large. If it is bombed with the target, it will cause significant harm to the body.

Accordingly, the main object of the present invention is to provide a grenade structure comprising a grenade body and a grenade head cover, the grenade body and the grenade head cover are all formed of a foamed material to form a light weight and burstable thickness, and squat After being shot and blasted, it will not cause harm to the human body.

A second object of the present invention is to provide a grenade structure in which the grenade body and the grenade head cover are assembled to each other, and the rough surface of the foamed material is used to make the tight fit assembly easy when combined.

A further object of the present invention is to provide a grenade structure in which the outer portion of the grenade body is further provided with a rifling type of dent, which provides a rapid rotation of the grenade body when it is ejected from the barrel, which not only accelerates the grenade body The speed of flight, and the debris generated during the explosion of the grenade body in flight, can continue to maintain a spiral flight, so that most of the BB bombs stored inside the missile body fly spirally to the target, reaching the mesh The purpose of scattering.

A further object of the present invention is to provide a grenade structure in which an inertial device is provided inside the grenade body, and a thimble is driven via the inertial device to explode the gunpowder chamber, thereby injecting most of the BB or paintballs.

A further object of the present invention is to provide a grenade structure in which an inertial device disposed inside a grenade body is composed of a spring and an inertial element fixed to the free end of the spring, and the ejector pin is mounted on the grenade in a movable manner. Within the shaft bore of the body, thereby initiating the thimble against the gunpowder chamber by controlling the firing speed of the grenade body.

In order to enable your review committee to further understand and understand the purpose, shape, construction device, features and functions of this new model, the following examples are combined with the drawings, which are described in detail as follows:

According to the grenade structure of the present invention, as shown in FIG. 2, the grenade 1000 is provided with a bullet cover 300 at the front end of the grenade body 200. The outer surface ring of the grenade body 200 is provided with an arc shape and a side slope and a body curvature. A barrel 400 is arranged in close proximity to the barrel of the transmitter (not shown), and a bullet cover 300 is disposed at the front end of the grenade body 200.

Referring to FIG. 3, the grenade of the present invention has a shaft hole in the center of the grenade body 200. 201, a thimble 51 is disposed in the shaft hole 201, and an inertia device 52 is disposed at the front end of the shaft hole 201. The bottom end of the shaft hole 201 is connected to a gunpowder chamber 53. An isolation layer 54 is disposed between the gun chamber 53 and the shaft hole 201. The inside is filled with gunpowder and is a confined space. The periphery of the shaft hole 201 is provided with a plurality of spaced-apartment elastic storage slots 21, and the inside of the elastic storage tank 21 can be filled with BB bombs or paintballs or the like.

As shown, the inertial device 52 is composed of a spring 521 and an inertial element 522 disposed at the free end of the spring 521, and the bottom of the spring 521 is fixed to the convex portion above the shaft hole 201.

Thereby, when the elastic force of the spring 521 is insufficient to support the inertial element 522 and the inertial element 522 is moved downward, the ejector pin 51 can be pushed by the inertial element 522, and the working end of the ejector pin 51 passes through the isolation layer 54 to ignite the gunpowder chamber. 53 internal gunpowder, and then the grenade body is blasted through the gunpowder, and then the BB or paintball stored inside the magazine 21 is injected, and when the thimble 51 acts on the gunpowder chamber 53, the ignition of the gun is triggered, and the range time is That is, the time when the gunpowder starts to reach the burst critical point, that is, the range and the time before and after the detonation need to cooperate with the time when the flight time of the pop-up hits reaches a preset distance, and then the projectile is exploded, and the work of the explosion is that the internal gunpowder is ignited and burned. In the differential manner, an internal pressure is generated inside the body of the grenade body 200, and the pressure value reaches a critical time period of the grenade body 200, and the time course of expanding the expansion of the grenade body 200 by the internal pressure is required. This time course is the detonation time course.

Please refer to FIG. 4 , the grenade of the present invention, since the grenade body 200 and the bullet cover 300 are both formed by foaming materials, the grenade body 200 and the bullet cover 300 are assembled in such a manner as to be engaged or bonded to provide a player. Self-assembling and determining the number of BB or paintballs placed in the magazine 21, wherein the front end of the grenade body 200 is a joint end, and the root portion 301 of the bullet cover 300 is provided with a sleeve combination, and both are foamed materials. The surface of the structure is rough, which facilitates the dry combination of hands and can be combined to obtain a fixed bonding force.

The grenade body 200 and the bullet cover 300 are all made of a foamed material, and a plurality of equiangularly spaced spacer teeth 400 are arranged around the outer circumference of the grenade body 200, and are integrally formed with the grenade body 200 as a foam material. The foam texture is fragile and is easily deformed by external force. In particular, the rigid object (such as the rifling body of the launcher barrel) has a corner portion to be cut, so that after the smashing, as soon as a strike is issued, the grenade body 200 The spacing between the teeth 400 and the rifling of the emitter barrel produces a grinding action that occurs on the premise that the width of the spacer 400 is the same as the barrel. When the line width dimension does not match, the spacer tooth 400 is easy to be worn with the barrel skein body by the foam material, and can be smoothly attacked and rotated by the specification of the barrel sill slope.

When the width of the spacer teeth 400 and the width of the barrel line are not adapted to the ambient temperature, or when the ratio of the foaming agent to the plasticizing material changes during the foaming operation, both of them are generated. As a result of the unsuitable scale, the spacer teeth 400 are easily squeezed by the squeezing action of the rigid rifling section of the barrel to solve the above problem.

Referring to FIG. 5, the grenade of the present invention has a sinusoidal slope and curvature on the outer surface of the grenade body 200, and is a plurality of equiangularly spaced spacer teeth 400 when it is shot out of the barrel. In the spiral state of flying while rotating, and when the grenade body 200 is quickly shot out of the barrel, the instantaneous acceleration causes the spring 521 inside the grenade body 200 to contract inward under the inertial force, so that the inertial element The 522 is pushed toward the ejector pin 51, and the ejector pin 51 is passed through the partition layer 54, and the gunpowder inside the gunpowder chamber 53 is detonated to explode the grenade body 200, thereby ejecting the BB projectile or the paintball stored inside the magazine.

As mentioned above, when the grenade body 200 is fired out of the barrel, it is a spiral flight state while flying, and the fragments of the grenade body 200 and the BB or paintballs after the explosion are also spiraled by inertia, thereby achieving The scattering strikes the target.

In summary, the grenade structure of the present invention has an unprecedented innovative structure, which is not found in any publication, and there is no similar product on the market, so that its novelty should be undoubted. In addition, the unique features and functions of this new model are far from comparable to the conventional ones, so it is indeed more progressive than the customary ones, and the patent application is in accordance with the provisions of the application requirements for new patents in the Chinese Patent Law.
