The specific embodiment

As shown in Figures 1 and 2.The present invention is located at the exhaust guide groove 80 that the rifling spacer 70 of gun barrel inner tubal wall 60 and most are located at 70 of this rifling spacers respectively by most rings and is formed, wherein respectively these rifling spacer 70 end faces 71 surround the trajectory space that painted ball passes through, and can reduce the friction of painted ball and inner tubal wall 60; Exhaust guide groove 80 dredging flows make the paintball gun performance shoot kinetic energy preferably.Below will describe in detail:

Rifling spacer 70 is strip, is located on the gun barrel inner tubal wall 60 arranged in a straight linely, which is provided with arcuation end face 71, and each arcuation end face surrounds the empty chamber of a nonocclusive circle, and this sky chamber is enough to form the painted ball transmission channel.When painted ball is launched, can reduce frictional force, reduce the resistance that painted ball outwards penetrates, and transmitting range is increased.Because frictional force reduces, the chance that painted ball breaks lowers relatively.

Exhaust guide groove 80 is located between each rifling spacer 70, and these exhaust guide groove 80 bottoms can also be gun barrel inner tubal wall walls.Each exhaust guide groove 80 forms the empty chamber of exhaust.When painted ball was launched, the exhaust guide groove formed flow-guiding channel, but dredging flow and make the resistance of painted ball reduce to minimum can be brought into play the best shooting kinetic energy of paintball gun.When painted ball breaks, playing slag will have most to flow in the exhaust guide groove 80 very naturally.Though there is sub-fraction bullet slag to stay on the rifling spacer 70, when shooting once more, new painted ball can push exhaust guide groove 80 with the bullet slag that part resides on rifling spacer 70 end faces, will partly play slag and directly release gun barrel, thereby significantly reduce the chance of smooth bore.The present invention makes the bullet slag that the painted ball of new emission can be released on the rifling spacer or the exhaust guide groove is interior, has the effect of automatic cleaning bullet slag.Therefore the dismounting gun barrel cleaning of need not stopping in recreation plays slag.

Exhaust guide groove 80 can be to establish to the gun barrel tail end from the gun barrel front end, also can be a section of gun barrel front end.

In sum, the design of rifling spacer 70 of the present invention helps the resistance of reducing friction, and the emission kinetic energy of paintball gun can effectively be brought into play.Exhaust guide groove 80 forms the gas-flow resistance that flow-guiding channel can reduce painted ball, and the space that persists that plays slag can be provided when painted ball breaks, and can prevent that again new painted ball from breaking again, even the situation of card bullet takes place.

For the painted ball and the difference that adapt to various unlike materials (for example: use N are shot kinetic energy ₂Or CO ₂Deng gas with various, then paintball gun has different shooting kinetic energy) paintball gun, rifling spacer 70 can be done corresponding adjustment with exhaust guide groove 80.For example, enlarge or reduce the area of rifling spacer 70 end faces 71, promptly increase or reduce the contact area of rifling spacer and painted ball; Increase or reduce the height of rifling spacer 70, the modes such as volume that promptly increase or reduce the exhaust guide groove are adjusted.

Be illustrated in figure 3 as the stereogram of one section of second embodiment of the invention gun barrel front end, wherein rifling spacer 70a both sides are provided with chamfering 72a, can further reduce the contact area of painted ball and rifling spacer.When painted ball was launched, chamfering 72a is dredging flow further.When painted ball breaks, play slag and can fall into exhaust guide groove 80a along the chamfering of both sides, in the hope of further reducing the bullet slag on the end face 71a, thereby can reduce the chance of new painted ball smooth bore.

Be illustrated in figure 4 as the stereogram of one section of third embodiment of the invention gun barrel front end, wherein the variable fillet 73a that is designed to of chamfering 72a.

Be illustrated in figure 5 as the front view of one section of fourth embodiment of the invention gun barrel front end, wherein the cross section of rifling spacer 70b is circular-arc.It is minimum that the area that this kind design makes painted ball 100 contact with the rifling spacer reduces to.When painted ball is launched, better water conservancy diversion effect can be arranged.When painted ball breaks, play the easier exhaust guide groove 80b that falls into both sides of slag.
