Bore Cleaning Device

Abstract

Disclosed is a gun bore cleaning device that improves the strong structure not to a fastened portion is not released at the time of reciprocating strikes of a cleaning brush, adds a shock damping structure, and provides benefits of a cost by minimizing its weight and use of materials. The gun bore cleaning device includes a hollow striking pipe; a hammer portion connected to a front end of the striking pipe, with a front portion protruding outward from the striking pipe and a rear portion being inserted into the striking pipe; a striking rod disposed in the striking pipe and penetrating the hammer portion to slide in forward and rearward directions, of which a front end being is formed with a cleaning brush fastening groove, and a tapered portion having a diameter increased from toward the front is formed on a rear side of the cleaning brush fastening groove; a rear strike portion disposed in the striking pipe and coupled to a rear end of the striking rod to strike a rear end surface of the hammer portion when the hammer portion moves backward; and a front strike portion provided with a cleaning brush fastened to the cleaning brush fastening groove, and a locking portion formed obliquely to correspond to the tapered portion, and fixed to the outside of the striking rod, so that as a rear end there of is stroked by the hammer portion, a shock is transmitted to the cleaning brush. Since the structure is strong, and the impact is dispersed by the structure of the rear strike portion and the damping portion, thereby increasing its durability and reducing noise. Also, the cleaning brush (60) is easily maintained, and it provides benefits of its cost by minimizing its weight and use of materials.

Description

technical field [0001] The present invention relates to a bore cleaning device (bore cleaning device), in particular to a bore cleaning device capable of using the impact force generated by a driving structure to clean the bore through a cleaning brush. Background technique [0002] Generally speaking, the bore refers to the through hole in the barrel of various artillery (guns), such as howitzers, direct sight artillery, tank guns, trench guns, and the like. To maintain the performance of the gun, the barrel should be kept clean. [0003] In one prior art, Korean Patent (No. 10-1058503) discloses a two-way inner hole cleaning device using manually applied impact force. like figure 1 As shown, the traditional inner hole cleaning device includes a tubular body 110 , a striking hammer body 210 , a guide rod 310 , a built-in rear striking plate 410 , a front striking plate 510 and a cleaning brush 610 . [0004] The interior of the tubular body 110 is hollow, and has a clean...

Problems solved by technology

[0010] However, according to the conventional inner hole cleaning device, the guide rod 310 is screwed to the front beating plate 510 through the front beating plate fastening portion 311, so that the thread fastening portion may be loosened due to long-time reciprocating sliding strikes, This results in incomplete bore cleaning and even makes maintenance difficult

[0011] In addition, if the rear side of the hammer body 210 hits the built-in rear striking plate 410, the impact absorption effect obtained by the protrusion 214 is still limited to the noise generated by the impact, so the built-in Less durable rear strike plate 410

When the guide rod 310 keeps still (kept) all the time, and even accidentally slides and draws (drawn) in the tubular body 110, it makes it difficult to drive the inner hole cleaning device, and also leads to safety accidents

If only the cleaning brush 610 needs to be replaced, or even the inner hole cleaning device, it will cause unnecessary consumption of materials
