Barrel for prohibiting paintball from dropping therefrom

#The present invention relates to a barrel of a paintball gun, which can prohibit the paintball from dropping therefrom.

#The barrel and the breech of a conventional paintball gun are combined by the threaded means. And the conventional paintball guns of both open-bolt type and closed-bolt type have the disadvantage: whenever a paintball is loaded in the breech without projecting at once, the paintball is very possible to slide within or even drop out of the barrel, which troubles the users a lot.

#Practically, the afore mentioned disadvantage is mitigated by installing a barrel with a bore diameter slightly smaller that the average diameter of the paintball. However, The narrowed barrel increase the friction to the projectile, so that the projection range is seriously reduced. What is worth, the paintball could possibly be stuck in the barrel or even cracked due to the size error of the paintball.

#FIG. 1 is a drawing showing a barrel of the present invention combining with a breech of the conventional paintball gun;

#FIG. 2 is a partial explosive drawing of a barrel in accordance with the first embodiment of the present invention;

#FIG. 3 is a partial diagram showing a barrel in accordance with the first embodiment of the present invention;

#Please refer to FIG. 1, the paintball gun includes a breech, and in the front of the breech is formed with a paintball loading hole. A portion in front of the loading hole is a first combining portion to combine with a barrel, i.e. a barrel 1 of the present invention.

#Please refer to FIG. 2 and FIG. 3. The barrel 1 of the present invention includes a main body 10 and an elastic ring 20. A rear end of the main body 10 is formed with a second combining portion 11 to combine with the first combining portion of the breech. An outer periphery of the combining portion 11 is formed with a threaded section, so as to be screwed onto the breech. An extension 12 with a smaller outer diameter than that of the main body 10 is extended rearward from the combining portion 11. A bore 13 penetrates the main body 10, the combining portion 11 and the extension 12.

#Around an outer periphery of the extension 12 is radially recessed to be formed with an annular groove 14 in which at least one non-circular slot 15 is formed, and the slot 15 communicates the annular groove 14 to the bore 13 proximately. Though the slot 15 is formed non-circularly, a plurality of slots may still be annularly arranged around the bore 13, as shown in figures. In addition, a perimeter of the elastic ring 20 is slightly smaller than that of the annular groove 14. The elastic ring 20 is disposed in the annular groove 14, and a part of the elastic ring 20 sinks into the slot 15 and is received in the bore 13. In other words, the elastic ring 20 is partially inserted and received in the bore 13 via the slot 15 from the annular groove 14. Since the elastic ring 20 is gradually inserted in the slot 15 and the bore 13 in a circular route, the insertion is described as sinking.
