Description

Double hose is prevented the duds pistol

Technical field

The utility model relates to the firearms technical field, and specifically a kind of double hose is prevented the duds pistol.

Background technology

The weapon that pistol exercises a public function as the police, sixty-four dollar question are at crucial moment the duds phenomenon to take place.In case of emergency, as: hostile takedown, Convention for the Suppression of Unlawful Seizure of Aircraft, violence-averse, particularly when the police closely stood facing each other with the suspect alone, requiring pistol to pull the trigger in moment must be successful, otherwise consequence is hardly imaginable.Existing automatic pistol is when if the duds situation occurring, then can only be press down hit mallet, the pulling sleeve is got rid of duds, make the bullet in the cartridge clip load again and can pull the trigger once more, but be not have such time and chance at this moment.Revolver has meets the characteristics that the duds situation can be changed the other bullet of percussion fast, but its existence shoots slow-footed shortcoming.Thus, how existing automatic pistol can not influence shooting meeting under the duds situation, and can get rid of duds fast, is that present firearms industry has a difficult problem to be solved.

Through to Chinese patent retrieval, do not find at present on automatic pistol, to be provided with and have the sublance pipe of kill capability, and utilize the percussion of sublance pipe to get rid of the technical scheme of duds fast.

Summary of the invention

The purpose of this utility model provides the anti-duds pistol of a kind of double hose, and what it can solve that existing automatic pistol exists is meeting influence shooting under the duds situation, and the problem that can't get rid of duds fast.

The purpose of this utility model is achieved through the following technical solutions: double hose is prevented the duds pistol, it comprise be respectively equipped with gun barrel, firing pin, hit mallet, the rifle body and the sleeve of trigger and guard ring, sleeve and rifle body are slidingly fitted, guard ring is hinged mutually with the rifle body, the sublance pipe is installed on the rifle body, and the sublance pipe is arranged on the bottom of gun barrel; Rifle body upper connecting rod cover, the pair that is provided with secondary firing pin hit bar and are installed in the bar cover, are slidingly matched each other, and secondary firing pin is arranged in the sublance pipe; Hit and offer half recess on the mallet; The rear side on rifle body top is offered recess; Switching mechanism is installed on the sleeve, on the sublance pipe transmission mechanism is installed, installation insurance mechanism on the rifle body; Switching mechanism front end and pair hit that bar is corresponding, the rear end respectively with hit that mallet and half recess are corresponding, the lower end is arranged in the recess; The transmission mechanism front end is connected with the sublance pipe, the rear end contacts with sleeve; Insurance institution's front end hits bar with pair respectively and the sublance pipe contacts, the rear end is hinged with trigger mutually by connecting pin.

For further finishing the purpose of this utility model, also can finish by the following technical programs: described sublance pipe comprises preceding gun barrel and the back seat pipe that is threaded mutually, offers hit pinhole on the back seat pipe, and secondary firing pin is arranged in the hit pinhole; Connect the supporting plate that is " U " shape on the guard ring, the bottom of gun barrel and back seat pipe before supporting plate is arranged on, and contact with it respectively; Resilient key is installed in the supporting plate, and resilient key contacts with back seat pipe rear end; Arc-shaped notch is offered in back seat pipe rear end, and arc-shaped notch communicates with the top of hit pinhole postmedian.Described switching mechanism comprises connecting lever and adjustment sheet, offers bar hole on the connecting lever, and it is protruding that the connecting lever lower end is provided with arc; Connect respectively on the sleeve and go up pivot pin and lower shaft pin, difference mounting spring on last pivot pin and the lower shaft pin, connecting lever is installed on the lower shaft pin by bar hole, is slidingly matched each other, and spring contacts with connecting lever and lower shaft pin respectively; Adjustment sheet is installed on the pivot pin, and spring contacts with adjustment sheet and last pivot pin respectively; Connect alignment pin on the connecting lever, it is recessed to offer arc on the adjustment sheet, and alignment pin and arc are recessed to cooperatively interact; It is corresponding that connecting lever front end and pair are hit bar, the connecting lever rear end respectively with hit mallet and half recess is corresponding, protruding being arranged in the recess of arc of connecting lever lower end.Described transmission mechanism comprises the gear frame that is circular arc, connects arc boss on the preceding gun barrel, and gear frame is arranged on the top of back seat pipe, and the gear frame front end is connected with arc boss, the rear end is corresponding with sleeve and contact.Described insurance institution comprises the connecting rod of mutual hinge and takes raker, connects locating shaft on the rifle body, takes raker and is installed on the locating shaft, is hinged each other; Connecting rod and company's pin are hinged; Take that the raker front end hits bar with pair respectively and the back seat pipe is corresponding and contact.

The beneficial effect that the utility model can produce: because of on existing automatic pistol, the sublance pipe being set, and the switching mechanism that matches with the sublance pipe, and offer on the mallet and corresponding half recess of switching mechanism hitting; This pistol is pulled trigger and is hit mallet bump firing pin when normal shooting, and the connecting lever upper end of switching mechanism this moment then enters in half recess that hits on the mallet, to avoid the being hit mallet bump, so do not influence the normal shooting of pistol; When the duds situation occurring, moment is pulled trigger more continuously, and the connecting lever rear end of switching mechanism this moment then breaks away from half recess, and corresponding with the no notch part that hits mallet, hit mallet bump connecting lever rear end this moment, connecting lever then forward the displacement transmission hit bar and pull the trigger bullet in the sublance pipe.Meanwhile, sleeve produces to return automatically under the effect of kick when the sublance pipe is pulled the trigger and removes, and the duds in the gun barrel is discharged, and another bullet in this moment cartridge clip then enters to be waited in the gun barrel to send out.Thus; the utility model disposes a sublance pipe again in the bottom of existing gun barrel; and on the rifle body, installed the match mechanism of percussion sublance pipe additional; in case the duds fault appears in gun barrel; the sublance pipe is in arm-to-arm at once, and it not only has certain lethality, but also can get rid of the duds in the gun barrel in percussion sublance pipe; make pistol moment can enter normal percussion state automatically, played the effect of rush-harvesting and rush-planting.The utility model be finished urgent public affair smoothly not only can for the police strong guarantee is provided, and the safety can guarantee that the police closely stands facing each other with the suspect alone the time, and extensive use can produce obvious social.
