Abstract
A bullet (or shell) features that both the head and case are shot out, other than only head, so increasing the utilization rate of matrial and simplifing the structure of gun. As the bore of gun becomes the part extended from gun barrel, higher sooting accuracy and longer range are realized. As the shell case does no need to dispose, so gun can work in closed condition or underwater. The soft contact between shell case and gun barrel can elongate the service life of gun barrel.
Description
The present invention relates to grenade and relate to firearms.
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 rifle (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 was removed before another rifle (big gun) bullet is packed into.
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 are directed at 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 is directed at rifle (big gun) pipe and distorts, and the high heat that produces can make the gunpowder blast ahead of time before percussion in rifle (big gun) bullet.
According to the present invention, rifle (big gun) bullet has comprised the front end ledge that gunpowder is housed usually at an interior shell case and a weight, and the bonnet that can separate that comprises detonating cap is attached on the shell case, and the arrangement that comes to this.In when shooting, the gunpowder explosion in the shell case, thereby the ledge that makes shell case comprise that rifle (big gun) plays front end separates from bonnet, and penetrates along rifle (big gun) pipe, just just rifle (big gun) that bullet provided was the same.
In the present invention, rifle (big gun) bullet penetrates parts one 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.
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 need not increase the size of rifle (big gun) bullet.The increase of bullet length helps improveing the degree of accuracy and the speed of bullet simultaneously, has also therefore increased the shooting distance of bullet.The length that bullet increases is no matter can make bullet keep stable and stoped bullet at rifle (big gun) pipe or in the aloft swing of air.
Best enforcement is front end ledge and formation of shell case of rifle (big gun) bullet, and in this case, the protuberance branch of front end is the prolongation of shell case periphery, and weight is placed by the protuberance branch of front end, reaches desired weight such as lead.
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, these gases at high pressure with regard to guaranteeing to produce because of gunpowder explosion, 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 simultaneously.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 is less than half that rifle (big gun) plays length, plays length and more preferably be less than rifle (big gun)
, the bigger ratio of rifle (big gun) bullet penetrates from rifle (big gun), and the material that the efficient of bullet is bigger and useless still less stays in the rifle (big gun).
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 that none size of bonnet is greater than rifle (big gun) bore, and bonnet is just easily by rifle (big gun) pipe like this, and it is all the same by rifle (big gun) pipe 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, and in this case, the gunpowder and the ignition charge of process water-proofing treatment are placed in the shell case, explode under the bump of striker, or ignite with traditional ignition method such as electric spark.
Select in one two under one the arrangement, after the emission of rifle (big gun) bullet, bonnet can be retained in the rifle (big gun), and in this case, bonnet can be with manually or with the ejection device removing.
Best enforcement be shell case slight contract carefully gradually, 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, and 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, this has facilitated provides a skewer to go into thing in conventional gun (big gun) thorax.Skewer is gone into the interior bore that thing has diameter of bore cooperation rifle (big gun) pipe, and uses as rifle (big gun) pipe of a prolongation.Traditional alternatively rifle (big gun) can be improved to providing make peace greatly rifle (big gun) pipe of a new interior diameter the same, and removes rifle (big gun) thorax that acts on as prolonging rifle (big gun) pipe.Further reach ground, rifle (big gun) can be designed to none than the supply of large diameter rifle (big gun) thorax.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 has just improved the degree of accuracy of rifle (big gun).After, the bullet that rifle (big gun) pipe shoots out is crossed in the footpath, and 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 etc.
The record of example of the present invention and prior art and contrast, and the accompanying drawing of reference is:
Fig. 1 shows the cross section of conventional gun (big gun) bullet.
Fig. 2 to 4 show that cross section root face plays according to rifle of the present invention (big gun) that example is finished and,
Fig. 2 A to 4A show that cross section basis and the roughly the same rifle (big gun) of which Fig. 2 to 4 play that example is finished and,
Fig. 5 shows that a cross section comprises that by rifle (big gun) thorax and part rifle (big gun) pipe rifle (big gun) bullet that is presented at Fig. 2 finishes.
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 in shell case 2 implodes.The gas that gunpowder 4 blasts produce forces bullet 1 rotation passing through rifle (big gun) pipe that separates from shell case.Shell case 2 tail ends 3 that sky gets off comprise that detonating cap 5 is retained in the rifle (big gun), advance rifle (big gun) thorax and rifle (big gun) machine door bolt must be regained so that withdraw from the shell case of crossing and allow new rifle (big gun) play skewer.
Fig. 2 shows first example of the present invention.Jie that rifle (big gun) bullet comprises says to generally tubular exterior wall 12 is used to hold gunpowder 4, and exterior wall 12 and 11 is to adhere to or monoblock forms.The example that shows at Fig. 2,11 is to form the exterior wall 12 of a prolongation and be filled with that plumbous exterior wall 12 is to dwindle gradually to increase the weight of the most advanced and sophisticated ledge of rifle (big gun) bullet, 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) caliber size.Show that as Fig. 5 rifle (big gun) comprises rifle (big gun) pipe 14 and rifle (big gun) thorax 15 that strengthens, and manages 14 when bullet along rifle (big gun) and penetrates, the thorax 15 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, skewer is gone into thing 16 and is placed in the thorax 15, the interior bore that skewer is gone into thing 16 roughly and rifle (big gun) pipe 14 and interior bore similar, the interior bore that the skewer that comprises rifle is gone into thing 16 cooperates the interior bore of rifle (big gun) pipe 14.Go into thing 16 in rifle (big gun) thorax 15 since install the skewer of a separation, 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.
Gunpowder 4 in shell case can be ignited with any traditional approach, for example striker bump detonating cap 15 or by electron production Da Hua.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 exterior wall of rifle (big gun) the bullet 12 outwards compressing interior wall that enables to go into rifle (big gun) pipe 14 and skewer thing 16 closely contacts.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 skewer go into thing 16 by the time, the rifle of going in the thing 16 with skewer in rifle (big gun) pipe 14 gives 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.Exterior wall 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, exterior wall 12 has strengthened the effectiveness of rifle (big gun) bullet after bullet 11.
Second example according to rifle of the present invention (big gun) bullet is presented at Fig. 3, and at this example, tail-hood 23 is to be placed between the exterior wall 22 of rifle (big gun) bullet.Rifle (big gun) bullet is placed in the rifle (big gun) identical with the method for first example.Bonnet 23 comprises a part that extends to outside the shell case, look like between the rib at two at 24,26 and recessed grooves 27 of the edge rib that two projections are arranged on the extension, 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 bullet make and play exterior wall 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 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 thing 16 is gone into for pipe 14 and skewer in automation ground.
The 3rd examples of implementation according to rifle of the present invention (big gun) bullet are presented at Fig. 4, this example second example of making peace greatly is similar, except shell case exterior wall 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 placed in and plays between the exterior wall 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 exterior wall (32) outside, edge rib 34,35 is born the injection in rifle (big gun) pipe, help to keep the location of the axis of rifle (big gun) bullet in 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 the slit can make rifle (big gun) bullet after percussion, the gas that is produced by blast leaks from body is peripheral.
Fig. 2 A, rifle (big gun) bullet that 3A and 4A the show Fig. 2 to 4 that makes peace greatly separately is similar, but described most advanced and sophisticated ledge 11a, 21a, 31a and shell case 12a, 22a, 32a be formed separately, and is bonded on the shell case.
