The present invention will be described in further detail with reference to specific embodiments thereof for the purpose of making apparent the objects, contents and advantages thereof.
The invention provides a gun body for launching fire extinguishing bombs, which comprises a gun muzzle brake 3, a gun barrel 1 and a gun tail 2 which are sequentially connected, and further comprises a connecting ring 4, a nut 5, a stop washer 6, a screw 7, a recoil collision block support arm 8, a collision block 9, a standing tooth 10, a key 11, a screw 12, a screw 13 and a washer 14;
the inner bore of the barrel 1 is divided into a medicine chamber part A, a slope chamber part B and a rifling part C from back to front, the medicine chamber part is used for accommodating a medicine cartridge, and the medicine cartridge is slightly conical in shape so as to be convenient for drawing out the medicine cartridge; the slope chamber part consists of two conical sections with different tapers, after the pills are filled in place, the belt is clamped into a section of slope chamber with a larger taper, so that the pills are ensured to have a correct initial position, the section of slope chamber with a smaller taper is arranged on the rifling and is the initial part of the rifling, and the slope chamber part has the functions of guiding the belt to be extruded into the rifling during launching and slowing down the abrasion of the initial part; the rifling part is provided with a plurality of right-handed mixed winding rifling lines which guide the projectile to rotate clockwise during launching so as to achieve the rotating speed required by stable flight of the projectile.
The size of the outer surface of the barrel 1 is gradually reduced from back to front in order to adapt to the change of the pressure in the bore, two sections of smooth cylindrical parts E at the rear part are guiding parts of the gun body, and the gun body slides back and forth along the cylindrical cradle by utilizing the parts when sitting and re-advancing. The outer cylinder at the tail end of the barrel 1 is matched with the gun tail 2, during installation, the mirror surface D at the tail end of the barrel 1 is attached to the mirror surface of the gun tail, the barrel is installed with the key 11 for preventing rotation, and then the barrel is screwed into the screw 12 for fixing. The front part of the barrel 1 is provided with a thread and anti-loose screw 7 mounting groove for mounting the muzzle brake 3.
The gun tail 2 is a square structure and is used for installing a gun bolt, fixing a semi-automatic device, and connecting the barrel 1 and a reverse recoil device (a parking machine and a re-advancing machine). The front part of the gun tail 2 is provided with threads to be connected with the connecting ring 4, and the mirror surface of the tail end surface of the barrel 1 is attached to the mirror surface of the gun tail 2 and is prevented from rotating by the key 11.
