Abstract

Disclosure relates to a bidirectional gun bore cleaning device for rapidly cleaning the bore of a gun barrel with less manpower by using a striking force (impact energy) of a striking hammer to easily move a cleaning brush in the bore. The bidirectional gun bore cleaning device is coupled to an end of the existing cleaning rod when being used.

Dependent claims

A bidirectional gun bore cleaning device using a manual impact force and configured to be coupled to an end of a cleaning rod for cleaning a bore of a gun barrel, the bidirectional gun bore cleaning device comprising:

a hollow tubular body (110) comprising a cleaning rod coupling portion (111) at a rear end thereof for coupling with the end of the cleaning rod (11), and a screw coupling portion (112) at a front end thereof;
a striking hammer body (210) comprising a rear hammer portion (211) having threads for coupling with the screw coupling portion (112) formed on the front end of the tubular body (110), a front hammer portion (212) formed in one piece with the rear hammer portion (211) and protruding forward, and a guide-rod passage hole (213) formed through center regions of the rear hammer portion (211) and the front hammer portion (212);
a guide rod (310) inserted in the striking hammer body (210) through the guide-rod passage hole (213) and slidable back and forth therein, the guide rod (310) comprising a front striking plate coupling portion (311) which is formed at a front end thereof and protrudes forward from the striking hammer body (210);
an internal rear striking plate (410) coupled to a rear end of the guide rod (310) and placed in the tubular body (110), the internal rear striking plate (410) functioning as a weight;
a front striking plate (510) comprising a striking face (511) formed on a rear end thereof and coupled to the front striking plate coupling portion (311) of the guide rod (310) for being struck by the front hammer portion (212) of the striking hammer body (210), and a cleaning brush coupling portion (512) formed on a front end thereof;
and
a cleaning brush (610) coupled to the cleaning brush coupling portion (512) of the front striking plate (510),
wherein if the cleaning rod (11) is pushed toward, the front hammer portion (212) of the striking hammer body (210) collides with the striking face (511) of the front striking plate (510) so that a striking force is transmitted to the cleaning brush (610), and if the cleaning rod (11) is pulled backward, a rear end of the rear hammer portion (211) of the striking hammer body (210) collides with the internal rear striking plate (410) so that a striking force is transmitted to the cleaning brush (610).
