Detailed Description

As shown in fig. 1-11, a caseless shell-less bullet gun with intermittent chamber-changing, its case 1 is used to combine all parts, on it is fixedly connected with barrel 2, locking iron 3, and inserted with bullet case 5 of column-shaped caseless bullet 4, its frame 6 is inserted in a frame base 7 fixed on the case and can be moved forward and backward, its tail end is supported against a recoil spring 8, and its head end is inserted and connected with a gun machine 9 which can be telescopically slided, and the above-mentioned all parts and their matching relationship and working principle are all the existent technology, and said gun is mainly characterized by that: a cylindrical cartridge chamber body 10 is arranged at the tail end of the gun barrel, the axis of the cylindrical cartridge chamber body is positioned above the gun barrel and is parallel to the gun barrel, and two cartridge chambers T1 and T2 are symmetrically arranged in the cylindrical cartridge chamber body and can be alternately aligned with the gun barrel along with the rotation of the cylindrical cartridge chamber body; the outer wall of the cartridge chamber body is sleeved with a cartridge chamber sleeve 11 for rotary fit, and the cartridge chamber sleeve is connected to a sleeve seat 12 (figures 1, 3 and 6) inserted in the case; a pawl 13 is arranged on the outer wall of the cartridge chamber body and is sleeved with a ratchet 14, and the ratchet can drive the pawl to rotate in a single direction together with the cartridge chamber body through ratchets arranged on the inner wall of the ratchet; the upper part of the ratchet wheel is connected with a pull rope 15 and a return tension spring 16 which respectively go down along the left side and the right side (figures 1, 4 and 6); the pull rope is pulled to the right side of the firearm after reaching the bottom of the ratchet wheel, passes through an L-shaped deflection sleeve 17 fixedly connected with a sleeve seat, turns 90 degrees backwards to be parallel to the barrel, and is connected with the head end of a longitudinal pull rod 18, the pull rod is inserted into a pull rod seat 19 fixedly connected with a receiver, and the head end is provided with an upward pull rod convex bamboo shoot 18a (figures 1 and 6); the lower end of the reset tension spring is connected to the turning sleeve; the upper side of a toggle piece 20 is fixedly connected with the upper side of the back of the root of the machine handle 21, the middle part of the toggle piece is arched and elastic, the lower side is a free end and is close to the lower side of the back of the root of the machine handle, and when the toggle piece is in a free state, the lower edge of the toggle piece is slightly higher than the upper edge of the convex bamboo shoot of the pull rod (figures 1 and 6); the transverse position of the poking piece is the same as that of the pull rod convex bamboo shoot (figure 2), and when the gun is locked, the poking piece is positioned in front of the pull rod convex bamboo shoot and the distance between the poking piece and the pull rod convex bamboo shoot is slightly larger than the unlocking distance of the gun (figure 5).

This is further explained below in connection with the firing process of the gun.

When using one chamber (like T1 chamber) of two chambeies to shoot and the chamber temperature is not high, need not to trade the chamber, can use this chamber to shoot (fig. 5) in succession, be equivalent to using the shooting of current fixed chamber firearm, its shooting action except take out shell action, the backseat of frame, reentry, the circulation action of the shooting such as unblanking, shutting of bolt, and bullet firing all are the same with current firearm: before shooting, the locking convex bamboo shoot 9a on the bolt forms locking with the locking clamp, pull the stock backward and make the frame move backward (namely the backseat), the setting groove 6a on the frame oppresses the shaping convex bamboo shoot 9b on the bolt to make the bolt rotate and unlock, after the backseat is in place (figure 6), the recoil spring promotes the frame and bolt to move forward again, the bolt carries on the bullet pushing (figure 7), after pushing the bullet into the bore, its front end surface supports and presses the rear end surface of the barrel body, make the front end surface of the barrel body support the rear end surface of the barrel (figure 8), the frame continues moving forward, its setting groove oppresses the setting convex bamboo shoot again to make the bolt reverse, form locking with the locking clamp (figure 9); after the bullet is fired, the machine frame recoils and repeats the above actions. During the period, the poking sheet is in a free state, the convex bamboo shoots of the pull rod can not be touched when the poking sheet moves back and forth, and the pull rod, the pull cable and the chamber body are kept still.

When the temperature of the T1 cartridge chamber is higher, the chamber can be changed, and the chamber changing action is as follows: holding the handle by hand, pressing the middle part of the flat poking sheet by a thumb to arch up, so that the lower edge of the flat poking sheet moves downwards and is lower than the upper edge of the pull rod convex bamboo shoot (figure 10), pulling the handle backwards to enable the machine frame rear seat and drive the gun bolt to unlock, enabling the lower part of the poking sheet to touch the upper part of the pull rod convex bamboo shoot, pressing the pull rod convex bamboo shoot to move backwards together with a pull rod and a pull rope, enabling the pull rope to pass through a turning sleeve, pulling a ratchet wheel to rotate anticlockwise, enabling ratchets on the inner wall of the ratchet wheel to apply tangential pressure on a pawl on a bullet chamber body, driving the bullet chamber body to rotate anticlockwise by 180 degrees, simultaneously stretching a reset tension spring, enabling a high-temperature T1 bullet chamber to be rotated upwards to be cooled, and enabling a low-temperature T2 bullet chamber to be rotated downwards (figure 11); when the machine frame is reset, the bolt pushes the bullet, the reset tension spring is contracted, the ratchet wheel is pulled to rotate backwards, the pull rod and the pull rope are simultaneously pulled to reset forwards, the bolt is locked when the machine frame is reset in place, and the ratchet does not generate tangential pressure on the pawl when the ratchet wheel rotates, so that the bullet chamber body cannot be driven to rotate, the T2 bullet chamber can be continuously left below for shooting, and when a certain number of continuous shooting is carried out to enable the bullet chamber to generate high temperature, the actions can be repeated to change the chamber so as to reduce the temperature. In addition, when the dumb ammunition appears, the ammunition chamber with the dumb ammunition arranged below can be rotated to the upper part for removing the dumb ammunition by the chamber changing action.

Through the intermittent chamber changing, the high-temperature cartridge chamber is timely cooled, so that the spontaneous combustion of the shell-free cartridge is avoided, and the ablation of the cartridge chamber is reduced; the chamber changing action can be synchronously completed by using the opportunity of replacing the magazine and the rear pull handle, so that the gun magazine is convenient and natural and the normal shooting is not influenced; the chamber is changed intermittently, and the chamber is not changed once like a firearm with continuously changed chambers, so that the working energy consumption and the vibration of the firearm are reduced; the two ammunition chambers can prolong the service life of the ammunition chambers, and the ammunition chamber body and the accessories thereof can be made into an independent module so as to be convenient for quick replacement and further prolong the service life of the firearms; the shell-free bullet rifle has the advantages of simple structure and light weight, can be made into a shell-free bullet rifle with an intermittent chamber changing function, and can also be made into a light and heavy shell-free bullet rifle with an intermittent chamber changing function, so that the application range is further expanded, the weight of a weapon system is reduced, the bullet carrying amount is increased, and metal materials are saved.
