Abstract

The present invention changes the traditional form of a grenade and a firearm. According to the present invention, a firearm pipe shoots out bullet heads and bullet cases, which increases the utilization rate of a material and also brings the prospect of improving and simplifying a structure of the firearm. The purposes of more accurate shooting and farther range are reached because a firearm chamber is changed into an extension part (lengthening 1/3-1/10) of the firearm pipe, and simultaneously, the firearm can work underwater in a closed mode because the bullet cases are not processed. Preferably, the bullet cases make soft contact with the firearm pipe during the shooting. The service life of the firearm pipe is prolonged, and chance is also provided for the development of the firearm without rifles, a triangle rocket missile, etc.

Description

Grenade

The present invention relates to grenade and firearms.Belong to the grenade technical field.

Traditional rifle (big gun) bullet comprises normally hard, a heavy metal bullets, and device has shell case one end of gunpowder in one, the other end of shell case be sealing and include a detonating cap.Rifle (big gun) bullet is that the back from rifle (big gun) thorax pushes, so the front end of inspection (big gun) bullet is placed between rifle (big gun) pipe, shell case is placed in rifle (big gun) thorax.Striker bump detonating cap when rifle (big gun) causes the gunpowder explosion in the shell case, makes bullet disengaging shell case and manages ejaculation along rifle (big gun).The empty-cartridge-case detonating cap of ining succession is retained in the rifle (big gun) afterwards, and the moving or ejection device of armrest is removed.

In the prior art, when bullet by rifle (big gun) when pipe, come off and make the distortion of rifle (big gun) pipe with regard to having the pettiness material in rifle (big gun) pipe.For example the rifle in bullet contact rifle (big gun) pipe makes bullet rotation when operation.The result that these materials come off spills the gas that produces because of gunpowder explosion between rifle (big gun) pipe and bullet, bullet will slow down like this along speed and swing that rifle (big gun) pipe penetrates, perhaps make bullet in rifle (big gun) pipe, depart from the axial-movement of setting.Further be that those materials from the loss of rifle (big gun) inside pipe wall finally cause rifle (big gun) tube failure.In addition, because bullet high-speed motion and manage with rifle (big gun) in rifle (big gun) pipe contacts, come off with the material of seasonal rifle (big gun) inside pipe wall, rifle (big gun) pipe will become more and more hotter.This just causes rifle (big gun) pipe to be distorted, and the high heat that produces can make the gunpowder blast ahead of time before percussion in rifle (big gun) bullet.---select from " the ammunition kingdom " the 12nd page, the 13rd page of weapon industry publishing house/1998 year publication in January.

Purpose of the present invention is in order to overcome the shortcoming of prior art, provides that a kind of bullet is fast along the speed that rifle (big gun) pipe penetrates, swing is high, alleviate the grenade of gun barrel heating.

Purpose of the present invention can reach by taking following measure: rifle (big gun) bullet, the bonnet that comprises detonating cap in comprising in the shell case of placing gunpowder in normally hollow out interior, heavy fore-end and one, this bonnet is attached to also separating with shell case on the shell case, it is characterized in that: the front end ledge of rifle (big gun) bullet and formation of shell case, the ledge of front end is as the prolongation of shell case periphery, and the ledge of front end is than other part lumping weights.

Purpose of the present invention also can reach by taking following measure:

Shell case forms with metal.

Shell case forms with plastic cement.

The thin material telogenesis of shell case exterior wall.

The length of bonnet is less than half of body outside length.

The length of bonnet is less than 1/4th of body length.

Shell case is around the peripheral flange of bonnet, forms prevent to get loose fastening.

Bonnet can be placed within the shell case.

The full-size of bonnet is less than the interior bore of rifle (big gun) pipe, can pass through rifle (big gun) pipe after emission.

Shell case reduces gradually along its length.

The shell case exterior wall is crooked, so that the bigger part of diameter is arranged on body.

Maximum gauge before the shooting is a little greater than the interior bore of rifle (big gun) pipe.

The cross section that has of bomb body is non-circular and perpendicular to its axis.

The inside diameter of rifle (big gun) thorax roughly and the interior bore of rifle (big gun) pipe similar, as rifle (big gun) pipe of a prolongation, act on.

Rifle (big gun) thorax comprises the diameter of bore that can the remove similar insert of bore in rifle (big gun) pipe of making peace greatly.

Rifle (big gun) thorax comprises rifle.

Bonnet and any other material automatically move and leave the tail end of rifle (big gun) pipe owing to gas pressure in the pipe or thorax of inspection (big gun).

Shell case can be removed by the tail end of rifle (big gun) pipe.

The end of shell case does not have bonnet.

The endoporus in the cross section of rifle (big gun) pipe is a garden shape.

Rifle (big gun) pipe does not comprise rifle.

Compared with prior art, the present invention has following outstanding advantage:

(1) rifle (big gun) bullet penetrates parts---the shell case comprise an essence from rifle (big gun), comprises heavy front end ledge in interior and originally as the packing of placement gunpowder.This preferential part be other material from rifle (big gun) thus penetrate and make more effective force of bullet, but do not need other material to make rifle (big gun) bullet as the shell case that holds gunpowder that penetrates in addition.According to like this, just utilize the material of making rifle (big gun) bullet more efficiently.

(2) according to the present invention, the length of rifle (big gun) bullet is that comparison conventional gun (big gun) bullet is long, and this provides one to reach the front end ledge that weight requires easily just may for heavy material, and does not need to increase the size of rifle (big gun) bullet.The length that bullet length increases is no matter can make bullet keep stable and stoped bullet at rifle (big gun) pipe or in the aloft swing of air.

(3) best enforcement is front end ledge and formation of shell case of rifle (big gun) bullet, and in this case, the ledge of front end is the prolongation of shell case periphery, and the ledge of front end can be placed weight, reaches desired weight such as lead.

(4) be more preferably, shell case is that metal forms, even if but other material, for example plastic cement can use too.Enclose on the limit of shell case is to form with thin material better.This is preferential part, explosive force can make the limit enclose outside expansion, thereby contact to greatest extent with the inwall of rifle (big gun) pipe, the gases at high pressure that this produces because of gunpowder explosion with regard to Bao Zheng, can not escape at the periphery of bullet, therefore whole strength of producing of gunpowder explosion can act on and promote bullet and advance, and the result is that bullet has a higher speed and increased shooting distance.Because easy deformation is enclosed on the shell case limit of rifle (big gun) bullet, this just have light relatively contact the limit enclose and rifle (big gun) inside pipe wall between occur, with regard to the material of minimum wearing and tearing rifle (big gun) pipe, therefore increase the life-span of rifle (big gun) pipe.The heat that this slight contact produces when reducing bullet by rifle (big gun) pipe when being both.More preferably be that the shell case limit encloses be material manufacturing with soft, can reduce the damage of rifle (big gun) pipe more.Best part is that bonnet length is less than rifle (big gun) and plays 1/4～1/2 of length, and the bigger ratio of rifle (big gun) bullet penetrates from rifle (big gun), and the efficient of bullet useless material bigger and still less stays in the rifle (big gun).

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 5 is the structural representation that the present invention is used in combination with firearms.

Fig. 2 shows embodiments of the invention 1.As can be seen from Figure 2, rifle (big gun) bullet comprises bullet 11, generally tubular shell 12 and back lid 3, bullet 11 and shell 12 disjunctors, and shell case 12 is used to hold gunpowder 4, and shell 12 and bullet 11 are to adhere to or monoblock formation, and back lid 3 is provided with detonating cap 15; In Fig. 2, bullet 11 is to form the shell 12 of a prolongation and be filled with lead to increase the weight of the most advanced and sophisticated ledge of rifle (big gun) bullet, and shell 12 is to dwindle gradually, at head a diameter that further strengthens is arranged.Bonnet 13 is used for sealing the gunpowder shell, and the outer outgoing plane of bonnet 13 is made fastening, and 11 of shell case is roughly finished.

According to rifle of the present invention (big gun) bullet be used in improved or the rifle (big gun) of particular design on, the rifle (big gun) of usual increasing rifle (big gun) thorax diameter is changed similar rifle (big gun) thorax of an internal diameter and rifle (big gun) mouth of pipe footpath size.As Fig. 5 demonstration, rifle (big gun) comprises rifle (big gun) pipe 14 and rifle (big gun) thorax 17 that strengthens, and manages 14 when bullet along station rifle (big gun) and penetrates, and the thorax 17 of increasing is that traditional being used for keeps shell case in rifle (big gun).

According to the present invention, require improvement back shooting gun (big gun) bullet, insert 16 is placed in the thorax 17, the interior bore of insert 16 roughly and the interior bore of rifle (big gun) pipe 14 similar, the interior bore that comprises the insert 16 of rifle cooperates the interior bore of rifle (big gun) pipe 14.Since the insert 16 that installs a separation is in rifle (big gun) thorax 17, better not as changing rifle (big gun) thorax that endoporus is done on request, perhaps rifle (big gun) installs an indissociable thorax that does not have than large diameter.

Bonnet 13 comprises that the edge rib of increasing and projection remains in the shell case 12 through extruding.

Gunpowder 4 in shell case can be ignited with any traditional approach, for example striker bump detonating cap 15 or electron production spark.The gas that gunpowder 4 blasts produce makes shell case 12 separate from bonnet 13 with bullet 11, and penetrates by rifle (big gun) pipe 14 rotatably, and bonnet 13 is retained in rifle (big gun) thorax 15.

Because high pressure is created in rifle (big gun) pipe, the shell 12 of rifle (big gun) bullet outwards compressing enables closely to contact with the interior wall of rifle (big gun) pipe 14 and insert 16.This has just guaranteed that bullet by rifle (big gun) pipe 14 o'clock, does not have gas to leak around bullet, when bullet along rifle (big gun) pipe 14 and insert 16 by the time, in rifle (big gun) pipe 14 with insert 16 in rifle give its rotation of an axis linear.Leave the tail end of rifle (big gun) pipe 14 at rifle (big gun) bullet after, heavy bullet 11 makes rifle (big gun) bullet fly to target exactly and promptly.Shell 12 adhere to or and the afterbody of bullet 11 form en bloc, help bullet correctly to fly.When rifle (big gun) attack to target, shell 12 has strengthened the effectiveness of rifle (big gun) bullet after bullet 11.

Fig. 3 shows embodiments of the invention 2.As can be seen from Figure 2, tail-hood 23 is to be placed between the shell 22 of rifle (big gun) bullet, and rifle (big gun) bullet is placed in the rifle (big gun) identical with the method for first example.As different from Example 1: bonnet 23 comprises a part that extends to outside the shell case, at 24,26 and recessed grooves 27 of the edge rib that two projections are arranged on the extension between two edge ribs, the outside dimension of bonnet 23 and length all are less than the interior bore of rifle (big gun) pipe, guarantee that bonnet 23 by rifle (big gun) pipe with can being regardless of tendency.Bonnet 23 comprises detonating cap 25, and when detonating cap 25 is subjected to lighting of striker bump or other any method, gunpowder 4 blasts in the shell case make shell case shell 22 and bullet 21 rotatably along rifle (big gun) pipe 14 directive targets.Relatively the little bonnet 23 of bore is separated in the back together in rifle (big gun) pipe, rifle (big gun) bullet rifle (big gun) the pipe tail end that flies out at a gallop, gas in pipe sprays to atmosphere up hill and dale, therefore just there is one air-flow in managing, to go out, this just absorbs bonnet 23 and passes rifle (big gun) pipe 14, does to remove and get ready for entering of next rifle (big gun) bullet so automation ground is pipe 14 and insert 16.

Fig. 4 shows embodiments of the invention 3.As can be seen from Figure 4, this example embodiment 2 that makes peace greatly is similar, except shell case shell 32 is along curved in length, so rifle (big gun) bullet has a maximum gauge part in the centre position, comprise in the dead ahead of rifle (big gun) bullet and to increase the weight of part 31, for example device is plumbous at the tip of rifle (big gun) bullet, at this example, bonnet 33 is settled between the shell case shells 32, a flange setting and prevent that bonnet 33 is pushed in the shell case.Rifle (big gun) bullet is remained in rifle (big gun) thorax by the

edge rib

34,35 of shell case shell 32 outsides,

edge rib

34,35 is born the injection in rifle (big gun) pipe, help to keep the location of the axis in rifle (big gun) the ammunition pipe 14 simultaneously, and guarantee that rifle (big gun) bullet had been provided with the slit at 14 o'clock on every side by managing.Because after the slit can make the percussion of rifle (big gun) ammunition, the gas that is produced by blast leaks from body is peripheral.

Fig. 2 A shows embodiments of the invention 4.As different from Example 1: fixedly connected by ring groove between bullet and the shell, all the other are with embodiment 1.

Fig. 3 A shows embodiments of the invention 5.As different from Example 2: fixedly connected by ring groove between bullet and the shell, all the other are with embodiment 2.

Fig. 4 A shows embodiments of the invention 6.As different from Example 3: fixedly connected by ring groove between bullet and the shell, all the other are with embodiment 3.

Show that as Fig. 1 traditional rifle (big gun) bullet comprises bullet 1 to be done by heavy material, typically comprises a metal-back of filling lead or other material that relatively weighs inside.Shell case 2 is filled gunpowder 4, detonating cap 5 devices are in the tail end 3 of shell case 2, and in use, rifle (big gun) bullet is to be placed in the rifle (big gun) to be placed in rifle (big gun) pipe with bullet 1, the legacy shell case of the rifle of ining succession (big gun) bullet and detonating cap are contained in rifle (big gun) thorax, are headed on by rifle (big gun) machine door bolt.On rifle (big gun) bullet thorax, pull trigger, striker bump detonating cap 5 makes gunpowder 4 play cosmos 2 implodes.The gas that gunpowder 4 blasts produce forces from the bullet 1 that plays the cosmos separation and rotates by rifle (big gun) pipe.Shell case 2 tail ends 3 that sky gets off comprise that detonating cap 5 is retained in the rifle (big gun), and rifle (big gun) machine door bolt must be regained so that withdraw from the bullet cosmos of mistake and allow new rifle (big gun) bullet reeve rifle (big gun) thorax.

Best enforcement is to finish one well to be enclosed between bonnet and the shell case, and shell case is around the outer circle of back cap surface, causes prevent to get loose fastening.Shell case provides for example the ejaculation design or the flange of a circle around the outer surface of bonnet, a better seal just can be finished, and the external diameter of shell case is made the diameter of a fastening circle flange greater than bonnet, preferential part is that bonnet can be configured between the shell case, in this case, gunpowder explosion in shell case, bonnet is ejected shell case, shell case and bullet penetrate along rifle (big gun) pipe, when bullet leaves rifle (big gun) pipe, just have one very fast high pressure draught to go out from rifle (big gun) pipe tail end, this necessarily absorbs bonnet and follows bullet, and (big gun) pipe tail end penetrates automatically to pass through rifle.Therefore, just need not after emission with staff or provide the ejection device to vacate rifle (big gun) thorax, improvement use and safer just can be oversimplified and obtain to rifle (big gun).In this case, best enforcement is none size of bonnet and greater than rifle (big gun) bore, bonnet is just easily by rifle (big gun) pipe like this, and it is to manage all equally by rifle (big gun) rotationally.It is very important that bonnet can not be clipped in rifle (big gun) pipe, because when another bullet emission, but owing to the bonnet that before had been clipped in rifle (big gun) pipe causes and can not penetrate along rifle (big gun) pipe, will make rifle (big gun) manage blast.

Best enforcement is that the bonnet of rifle (big gun) bullet forms with metal, even if other material, for example plastic cement can use equally.

Better enforcement is that rifle (big gun) bullet does not have bonnet, in this case, places in the shell case through the gunpowder and the ignition charge of water-proofing treatment, explodes under the bump of striker, or ignites with traditional ignition method such as electric spark.

Select in one two under the arrangement, after the emission of rifle (big gun) bullet, the bonnet people is retained in the rifle (big gun), and in this case, bonnet can be with manually or with the ejection device removing.

Contracting gradually that shell case is slight during best enforcement is thin, but the diameter that a part arranged is a little greater than the interior bore of rifle (big gun) pipe.In this case, manage when sagging when rifle (big gun), rifle (big gun) bullet can not fall, but works as gunpowder explosion, and the strength of generation enough changes shell case and makes it pass through rifle (big gun) pipe.In addition, this guarantees that rifle (big gun) bullet remains on the origin-location when the striker bump of rifle (big gun).During percussion, any displacement before rifle (big gun) bullet all can influence the ignition of ignition medicine.The overall diameter of shell case may be to strengthen gradually along its length, and the diameter at shell case rear portion is greater than the tip of rifle (big gun) bullet.But more preferably be shell case along its length to having one between the afterbody than the major diameter part, this plays improvement on the aerodynamic property for rifle (big gun), one of them is to pass air more efficiently.

It is circular that rifle (big gun) bullet has a cross section, or different shapes.Triangle for example, best enforcement is form fit rifle (big gun) bullet of the endoporus of rifle (big gun) pipe.

Detonating cap in the bonnet can perhaps have an ignition to ignite gunpowder by the striker percussion of rifle (big gun).Must pass through rifle (big gun) pipe as shell case, this is used for special rifle (big gun) with regard to the more tiny diameter of relative conventional gun (big gun) bullet is arranged.Because usual rifle (big gun) bullet has one than the big size of bore in rifle (big gun) pipe, rifle (big gun) bullet is remained in rifle (big gun) thorax.According to this preferential part, just make rifle (big gun) thorax that a diameter that reduces than conventional gun (big gun) thorax can be provided, so the internal diameter with rifle (big gun) pipe is identical to greatest extent for rifle (big gun) thorax, just having facilitated provides an insert in conventional gun (big gun) thorax.Insert has a diameter of bore to cooperate the interior bore of rifle (big gun) pipe, and use as the rifle (big gun) of prolongation pipe, traditional alternatively rifle (big gun) can be improved to providing make peace greatly rifle (big gun) pipe of a new diameter of bore the same, and removes rifle (big gun) thorax that acts on as prolonging rifle (big gun) pipe.Further, rifle (big gun) can be designed to none big internal orifice dimension rifle (big gun) thorax supply.Under any circumstance, the override part is that rifle (big gun) thorax comprises that the rifle deallocation closes rifle (big gun) pipe.It is identical with bore in rifle (big gun) pipe substantially that the result provides a rifle (big gun) thorax, and particularly rifle (big gun) thorax has rifle, and this rifle (big gun) that just extended is managed, thereby improved the degree of accuracy of rifle (big gun).After, through the bullet that rifle (big gun) pipe shoots out, it is farther that relatively rifle (big gun) thorax is not done the flight stability and the range that prolong rifle (big gun) pipe.Except being fit to the rifle (big gun) of a rifle (big gun) thorax, also be fit to the rifle (big gun) that has one group of parallel rifle (big gun) thorax to provide in the runner.In this case, a rifle (big gun) thorax can be adorned a rifle (big gun) bullet, and rotating wheel makes a rifle (big gun) bullet align rifle (big gun) pipe, and when bullet penetrates from rifle (big gun) thorax, runner rotates another rifle (big gun) bullet is managed over against rifle (big gun).

Rifle of the present invention (big gun) bullet can be used for the rifle (big gun) of virtually any size, comprises pistol, and rifle adds grand big gun etc.
