Abstract
The utility model discloses a chamber mechanism of a firearm. The chamber mechanism of the firearm comprises a frame, a chamber, a mandrel, a cam, a pull rod, a barrel, an ejector rod and a return spring; the mandrel is rotatably connected with a mandrel hole in the frame, one end of the mandrel is fixedly connected with the chamber, and the other end is fixedly connected with the cam; the chamber is provided with a plurality of chamber holes; the cam is provided with a rotation groove, the middle portion of the rotation groove is a spiral groove, and both ends of the rotation groove are straight grooves; the pull rod and the frame are in slip assembly, and one end of the pull rod is provided with a pull rod pin matching with the rotation groove of the cam; the barrel is fixedly connected with the frame and arranged below the cam, and one end of the barrel penetrate the frame; the ejector rod is connected with an ejector rod hole of the frame; the return spring is mounted on the ejector rod, one end of the return spring abuts against a stopper of the ejector rod, and the other end abuts against the frame; when the pull rod slips on the frame, the pull rod abuts against the end surface of the ejector rod to push the ejector rod to stretch into the chamber hole. The chamber mechanism of the firearm solves the problem of bullet ejector of a chamber turning firearm firing shell-free bullets and is simple in structure.
Description
Technical field
The utility model relates to a kind of firearms, especially a kind of cartridge chamber mechanism of firearms.
Background technology
The cartridge chamber of existing Zhuan Tang mechanism firearms, bullet of every transmitting all will rotate and once change thorax, the complex structure of this cartridge chamber mechanism, and existing Zhuan Tang mechanism firearms are all metal cartridge bullets of transmitting, and can not launch caseless cartridge, caseless cartridge does not have the rigidity root edge of metal cartridge bullet, can not extract by extractor pull, now fixing cartridge chamber firearms carry out caseless cartridge and extract more difficultly, and this mechanism is for solving the problem that extracts of caseless cartridge.
Summary of the invention
The purpose of this utility model is to provide a kind of problem that extracts that solves revolver guns tool transmitting caseless cartridge, and the cartridge chamber mechanism of firearms simple in structure.
Above-mentioned purpose, the technical solution of the utility model is: a kind of cartridge chamber mechanism of firearms, comprise the body of a gun, cartridge chamber, mandrel, cam, pull bar, gun barrel, ejector and back-moving spring, core axle hole in mandrel and the body of a gun is rotationally connected, one end of mandrel is fixedly connected with cartridge chamber, the other end is fixedly connected with cam, cartridge chamber is provided with multiple cartridge chambers hole, cam is provided with rotation slot, the interlude of rotation slot is helicla flute, the two ends of rotation slot are straight trough, pull bar and body of a gun slippage assembling, one end of pull bar is provided with the stay rod pin coordinating with the rotation slot of cam, gun barrel is fixedly connected on the body of a gun, and be positioned at cam bottom, and stretch out outside the body of a gun one end of gun barrel, the ejector hole load of ejector and the body of a gun, back-moving spring is sleeved on ejector, and the backstop of one end and ejector offsets, the other end and the body of a gun offset, when pull bar is on the body of a gun when slippage, the end face of pull bar and ejector offsets, and promote ejector and stretch in cartridge chamber hole.
Adopt after said structure, in the time that revolver guns tool need to load caseless cartridge, after firearms battery has fired, while pushing away boring, as long as pull pull bar, the stay rod pin band moving cam of pull bar rotates, cam driven mandrel rotates, mandrel drives cartridge chamber to rotate, last pull bar compressing ejector, ejector is stretched in cartridge chamber hole, shell case in cartridge chamber hole is released, realize the process that once extracts, in the time that the rotation slot of cam is made, the interlude of rotation slot is helicla flute, the two ends of rotation slot are straight trough, in the time that stay rod pin is positioned on straight trough, cam can not rotate, therefore ejector can stretch into ejection in cartridge chamber hole, therefore above simple in structure, and realize the problem that extracts of revolver guns tool transmitting caseless cartridge.
Brief description of the drawings
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the expanded view of Fig. 1 cam.
Detailed description of the invention
The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.
Referring to Fig. 1, shown in 2, a kind of cartridge chamber mechanism of firearms, comprise the body of a gun 1, cartridge chamber 2, mandrel 3, cam 4, pull bar 5, gun barrel 6, ejector 7 and back-moving spring 8, mandrel 3 is rotationally connected with the core axle hole 1-1 in the body of a gun 1, one end of mandrel 3 is fixedly connected with cartridge chamber 2, the other end is fixedly connected with cam 4, cartridge chamber 2 is provided with multiple cartridge chambers hole 2-1, cam 4 is provided with rotation slot 4-1, the interlude of rotation slot 4-1 is helicla flute 4-1-1, the two ends of rotation slot 4-1 are straight trough 4-1-2, pull bar 5 and the body of a gun 1 slippage assembling, one end of pull bar 5 is provided with the stay rod pin 5-1 coordinating with the rotation slot 4-1 of cam 4, gun barrel 6 is fixedly connected on the body of a gun 1, and be positioned at cam 4 bottoms, and stretch out outside the body of a gun 1 one end of gun barrel 6, the ejector hole 1-2 load of ejector 7 and the body of a gun 1, back-moving spring 8 is sleeved on ejector 7, and the backstop 7-1 of one end and ejector 7 offsets, the other end and the body of a gun 1 offset, when pull bar 5 is on the body of a gun 1 when slippage, pull bar 5 offsets with the end face of ejector 7, and promote ejector 7 and stretch in the 2-1 of cartridge chamber hole.
Referring to Fig. 1, shown in 2, when the utility model uses, in the time that revolver guns tool need to load caseless cartridge, after firearms battery has fired, while moving back boring, as long as pull pull bar 5, the stay rod pin 5-1 of pull bar 5 rotates because of the effect band moving cam 4 of helicla flute 4-1-1, cam 4 is with moving mandrel 3 to rotate, last mandrel 3 drives cartridge chamber 2 to rotate, when the stay rod pin 5-1 of last pull bar 5 is positioned at straight trough 4-1-2, stay rod pin 5-1 oppresses ejector 7, ejector 7 is stretched in the 1-2 of cartridge chamber hole, shell case in the 1-2 of cartridge chamber hole is released, the center line of cartridge chamber hole 2-1 and the center line of ejector 7 same axially on, therefore above simple in structure, and realize the problem that extracts of revolver guns tool transmitting caseless cartridge.
