Description

Barrel mediation structure

Technical Field

The utility model relates to a firearms maintenance technical field specifically indicates a barrel mediation structure.

Background

The barrel is one of the main components of the firearm, and is usually made of a heat-resistant and non-deformable metal tube, and is connected to the chamber, so that when the bullet is fired, the expanding gas generated by the explosion or pressure of gunpowder or other power can push the bullet through the barrel, and finally the bullet becomes a high-speed projectile to be ejected.

Due to the special structural characteristics of the gun barrel, the cleaning of the interior of the gun barrel has certain difficulty. The existing gun barrel wiping is generally implemented by connecting a strip-shaped copper rod with a brush and then penetrating into a gun barrel to wipe back and forth. However, in the method, firstly, the copper wire is relatively hard, secondly, the cost is high, and the copper rod cannot be deformed and bent, so that great inconvenience is brought to soldiers and soldiers in firearm maintenance.

In view of the above problems, application No.: 201810874810.8 discloses a multifunctional barrel wiping structure, which comprises a wiping handle, a wiping rod, a first wiping head, a second wiping head and a third wiping head; the first wiping head, the second wiping head and the third wiping head are all provided with a hairbrush head and a first male joint detachably connected to the first female joint. Compared with the prior art, the efficiency of wiping the gun barrel by the soldier is improved, but in the wiping process, the wiping material is easily clamped in the gun barrel and is difficult to take out. Because there is not the instrument of suitable clearance plug, some adopt the mode of burning by fire, metal pole striking will clean the material and burn or strike, cause the outer bonderizing layer of barrel to drop, barrel material hardness reduces, and the barrel inner wall is impaired, leads to gun to damage unable the use.

Therefore, a barrel unblocking structure for clearing the blockage in the long gun barrel is needed in order to solve the technical problems described above.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is overcome the defect of above-mentioned technique, provide a barrel mediation structure, the purpose is connected drill bit and other instruments through the connecting rod, and is equipped with the protection tube in order to reach the technological effect of protection barrel inner wall at drill bit outer lane cover, objective solution the barrel clean the maintenance in-process clean the technical problem of material card jam in the barrel.

In order to solve the technical problem, the utility model provides a technical scheme does: a barrel dredging structure comprises a connecting rod and a drill bit, wherein the drill bit is a long drill bit, a protective tube is sleeved outside the drill bit, and an inner square hole matched with the connecting rod is formed in one end of the neck of the drill bit;

one end of the connecting rod is provided with a square head matched with the inner square hole, and the other end of the connecting rod is provided with a hexagonal connecting column.

Furthermore, the drill bit is a twist drill which is made of stainless steel.

Compared with the prior art, the utility model the advantage lie in:

the utility model connects the drill bit with other tools through the connecting rod, drives the drill bit to rotate in the gun barrel to clean up the blockage, and achieves the technical effect of dredging the gun barrel; the protective tube sleeved on the outer ring of the drill bit can effectively prevent the inner wall of the gun barrel from being damaged when a blockage is cleared. The utility model has the advantages of simple and reasonable design, convenient operation can with other instrument cooperations such as pistol drill, the practicality is strong.
