Description

Technical Field

[0001] The utility model relates to the field of automatic cartridge ejectors, in particular to a remotely controllable full-automatic cartridge ejector. Background Technique

[0002] When the existing separate-packed projectiles are loaded into the gun barrel, a cartridge loader is used for cartridge loading. Due to the large cartridge loading force, the copper cartridge belt on the outer ring of the projectile is directly stuck into the starting part of the rifling under the action of external force to achieve the purpose of sealing the gun barrel, which also directly leads to a large external force required for cartridge ejection. At present, most of them mainly use manual cartridge ejectors for cartridge ejection. The external part of the manual cartridge ejector is cylindrical and has the same size as the firearm caliber to facilitate the positioning of the manual cartridge ejector in the gun barrel. The internal part is a conical hollow to stagger the fuze and closely cooperate with the conical part of the projectile. When receiving force during cartridge ejection, the projectile can be directly pushed out.

[0003] During manual cartridge ejection, a wooden scrubbing rod is threadedly connected to the manual cartridge ejector, and the manual cartridge ejector is pulled to reciprocate in the gun barrel through the wooden scrubbing rod, or the rod is knocked with an external force to eject the projectile from the gun barrel. However, due to the large force received by the projectile when it is loaded into the gun barrel and the rifling is closely attached to the projectile cartridge belt, it is difficult to perform manual cartridge ejection, and sometimes the wooden scrubbing rod will be directly damaged. Moreover, in special environments such as plateaus, the physical strength of personnel is consumed greatly, and there are also certain safety hazards. It is difficult to perform cartridge ejection safely and quickly.

[0004] Therefore, it is necessary to provide a new remotely controllable full-automatic cartridge ejector to solve the above technical problems. Content of the Utility Model

[0027] The positioning plate 42 is installed at the impact hole position of the muzzle brake to fix the force receiving end, so as to provide a reaction force for the fully automatic cartridge extractor when ejecting the cartridge.

[0028] The positioning ring 41 is screwed on the connecting part of the support rod 31 for positioning in the gun chamber and bearing the radial force of the force support, ensuring that the force is concentrated on the actuator and the cartridge;

[0029] The inside of the cartridge extractor head 2 is a conical hollow setting, used to avoid the fuse and fit closely with the cartridge, so as to bear the backward ejection force when the actuator works.

[0030] Reference Figure 2 and Figure 3 As shown, two side plates 5 are symmetrically provided on the side wall of the positioning plate 42. Plug posts 51 are fixedly connected to both of the two side plates 5. Two plug ears 52 are symmetrically provided at the nozzle of the gun barrel 1.

[0031] It should be noted that: The positioning plate 42 is pressed against the muzzle, so that the plug posts 51 on the two side plates 5 are slidably inserted into the through holes in the two plug ears 52, and the positioning and installation are quickly completed.

[0032] Reference Figure 2 and Figure 3 As shown, through holes are provided on both of the two plug ears 52, and the two plug posts 51 are respectively slidably connected to the through holes on the two plug ears 52.

[0036] It should be noted that: When the inclined surfaces of the catch heads 53 on the two plug posts 51 move to abut against the two through holes, the two catch heads 53 can automatically retract into the two grooves. At the same time, the two catch heads 53 reset and extend out, and their planes abut against the two plug ears 52, so as to automatically complete the locking of the positioning plate 42.
