Dual cartridge feed mechanism

Abstract

The barrel is located at the front of the gun body, the firing mechanism at the rear, and the magazine well is located in the middle. Two magazines are inserted into the magazine well in series. When the rear magazine is empty, there are no bullets obstructing the barrel, allowing the firing mechanism to move forward via a drive head, pushing the slide and the left and right magazine ejectors. When the cones on the left and right magazine ejectors push open their corresponding muzzle brakes, the empty rear magazine automatically detaches. After the rear magazine detaches, the firing mechanism and the front magazine can be pulled back and moved along the track to the original position of the rear magazine using both hands simultaneously. Once the front magazine is in position and locked by the muzzle brakes and positioning devices, the trigger can be pulled to fire again. Simultaneously, a third magazine can be removed and inserted into the inner hole at the front of the magazine well during continuous firing, thus reducing the time spent pausing fire due to magazine changes.

Description

Technical Field

[0001] This invention relates to a magazine feeding mechanism, and more particularly to a dual-magazine feeding mechanism that can shorten magazine changing time by connecting two magazines in series. Background Technology

[0002] Currently, it is known that firearms may pause firing during magazine changes, and the length of this pause directly affects the safety of soldiers. Summary of the Invention

[0003] To overcome the shortcomings of existing firearms with long magazine replacement times, this invention provides a dual-magazine feeding mechanism. This mechanism shortens magazine replacement time by connecting magazines in series, thereby improving the firearm's combat effectiveness and ensuring the safety of soldiers.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention includes a gun body, a magazine, a recoil stop, a magazine ejector, a positioning device, a firing mechanism, a barrel, a bullet, a boss, a slider, a drive head, a track, a groove, a top cone, and a spring.

[0005] The gun body has a cylindrical structure, and the magazine well has a rectangular shell structure. The barrel is located at the front axis of the gun body, and the firing mechanism is located at the rear axis of the gun body. A drive head is connected to the lower rear of the firing mechanism. A slider is located in a groove inside the gun body and corresponds to the position of the drive head on the firing mechanism. A return spring is installed between the slider and the gun body. The magazine well is vertically connected to the middle of the gun body. Two lifting tracks, one lower at the front and one higher at the rear, are respectively provided on the left and right inner shell walls of the magazine well. These tracks are raised tracks formed by two parallel sections of slide rails at the front and rear and a middle section of upward-sloping slide rail. Several grooves are cut into each of the left and right tracks to vertically cut through them. Bosses corresponding to the grooves on the tracks are provided at the upper ends of the left and right outer surfaces of the magazine. The magazine has a traditional straight magazine structure. Several recoil stoppers are respectively installed on the left and right outer shell walls of the receiver, corresponding to the grooves on the track. The recoil stoppers are longitudinally arranged hook-shaped spring plate structures. The upper end of the recoil stopper is connected to the outer shell wall of the receiver, and the lower hook end of the recoil stopper is inserted into the groove on the track through a through hole in the receiver shell wall and is flush with the track. Two magazine ejectors are respectively installed at the rear end of the left and right outer shell walls of the receiver. The magazine ejectors are long strip plate structures, perpendicular to the recoil stoppers, and positioned between the rear end of the receiver and the outer shell wall of the receiver. Each magazine ejector has a top cone corresponding to each recoil stop it contacts. The rear end of each magazine ejector is connected to a slider located in the gun body via a horizontal axis. Two positioning devices are respectively installed at the rear end of the left and right inner shell walls of the receiver. The positioning devices are spring plate structures and are parallel to the magazine ejectors. The front end of the positioning device is connected to the shell wall of the receiver, and the rear end of the positioning device bends and extends into the inner hole of the receiver, corresponding to the position of the boss on the magazine. When the two magazines are inserted into the front and rear positions of the magazine holder, respectively, the magazines slide through the groove on the magazine holder track via the boss and are locked by the anti-recoil device.

[0006] During firing, the firing mechanism pushes the bullets from the rear magazine into the barrel and fires them. Because the bullet's tail protrudes beyond the rear end of the barrel, it obstructs the firing mechanism, preventing the drive head on the firing mechanism from driving the slider in the gun body. When the rear magazine is empty, the barrel is no longer obstructed by bullets, allowing the firing mechanism to push the slider and the left and right magazine ejectors forward via the drive head. As the ejector cones on the left and right magazine ejectors push open their corresponding muzzle devices, the empty rear magazine automatically detaches.

[0007] After the rear magazine falls off, you can use your left and right hands to pull the firing mechanism backward and push the front magazine along the track to the position of the original rear magazine. When the front magazine is in place and locked by the anti-recoil device and the locator, you can pull the trigger to fire again. At the same time, during continuous firing, you can take out the third magazine and insert it into the inner hole at the front of the magazine well, thus shortening the time that the firing is interrupted due to changing magazines.

[0008] The beneficial effect of this invention is that by using a series of magazines, the time required to change magazines is shortened, thereby improving the combat effectiveness of the firearm and ensuring the safety of soldiers. Attached Figure Description

[0023] exist Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 10 , Figure 12In this design, the gun body 1 has a cylindrical structure, and the magazine 2 has a rectangular shell structure. The barrel 8 is located at the front axis of the gun body 1, and the firing mechanism 7 is located at the rear axis of the gun body 1. A drive head 12 is connected to the lower rear end of the firing mechanism 7. A slider 11 is located in a groove inside the gun body 1 and corresponds to the position of the drive head 12 on the firing mechanism 7. A return spring 13 is provided between the slider 11 and the gun body 1. The magazine 2 is vertically connected to the middle of the gun body 1. Two lifting tracks 14, one lower at the front and one higher at the rear, are respectively provided on the left and right inner shell walls of the magazine 2. The tracks 14 are raised tracks formed by two parallel slide rails at the front and rear and a middle section of upward-sloping slide rail. Several grooves 15 are provided on the left and right tracks 14 to vertically cut through the tracks 14. The upper ends of the left and right outer shell surfaces of the magazine 3 are provided with bosses 10 that correspond to the grooves 15 on the tracks 14. The magazine 3 has a traditional straight magazine structure. Several anti-recoil devices 4, corresponding to the grooves 15 on the track 14, are respectively provided on the left and right outer shell walls of the receiver 2. The anti-recoil devices 4 are longitudinally arranged hook-shaped spring plate structures. The upper end of the anti-recoil device 4 is connected to the outer shell wall of the receiver 2, and the lower end of the anti-recoil device 4 is inserted into the groove 15 on the track 14 through a through hole opened in the shell wall of the receiver 2 and is flush with the track 14. Two magazine ejectors 5 are respectively provided at the rear end of the left and right outer shell walls of the receiver 2. The magazine ejectors 5 are long strip plate structures. The magazine ejectors 5 are perpendicular to the anti-recoil devices 4 and are located between the rear end of the receiver 2 and the outer shell wall of the receiver 2. Each of the left and right magazine ejectors 5 is provided with a top cone 16 corresponding to each contacting anti-recoil device 4. The rear end of each of the left and right magazine ejectors 5 is connected to the slider 11 located in the gun body 1 through a horizontal axis. Two locators 6 are respectively located at the rear ends of the left and right inner shell walls of the magazine holder 2. The locators 6 are spring plate structures and are set parallel to the magazine ejector 5. The front end of the locator 6 is connected to the shell wall of the magazine holder 2, and the rear end of the locator 6 is bent and extends into the inner hole of the magazine holder 2, corresponding to the position of the boss 10 on the magazine 3. When the two magazines 3 are inserted into the front and rear ends of the inner hole of the magazine holder 2 respectively, the magazines 3 slide through the groove 15 on the track 14 of the magazine holder 2 via the boss 10 and are locked by the anti-reverse device 4.

[0024] exist Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12During firing, the firing mechanism 7 pushes the bullet 9 from the rear magazine 3 inside the magazine holder 2 into the barrel 8 and fires it. Simultaneously, because the tail end of the bullet 9 in the barrel 8 extends beyond the rear end of the barrel 8, it obstructs the firing mechanism 7, preventing the drive head 12 on the firing mechanism 7 from driving the slider 11 in the gun body 1. When the bullet 9 in the rear magazine 3 is depleted, the barrel 8 is no longer obstructed by the bullet 9. Therefore, the firing mechanism 7 can then push the slider 11 and the left and right magazine ejectors 5 forward together via the drive head 12. When the respective cones 16 on the left and right magazine ejectors 5 push open their corresponding anti-recoil devices 4, the rear magazine 3, now empty of bullet 9, automatically detaches. After the rear magazine 3 falls off, you can use your left and right hands to pull the firing mechanism 7 backward and push the front magazine 3 along the track 14 to the original position of the rear magazine 3. When the front magazine 3 is in place and locked by the anti-recoil device 4 and the locator 6, you can pull the trigger to fire again. At the same time, during continuous firing, you can take out the third magazine 3 and insert it into the inner hole at the front of the magazine holder 2, thus shortening the time of pausing firing due to changing the magazine 3.
