Description

Dumb bullet removing device of shell-free firearm

The technical field is as follows: the invention relates to a firearm device, in particular to a dummy ammunition removing device of a shell-less firearm.

Background

The caseless shell firearm has the outstanding advantages of light weight, metal saving and the like, but because the strength of the explosive column is low, when a dumb shell appears, the dumb shell cannot be pulled out by adopting a shell pulling hook like a shell-carrying bullet, and some caseless shell firearms use a rotary type chamber to remove the dumb shell, but the structure is complex, the transverse size is large, and the front end of the chamber and the barrel are not integrated, so the gas leakage is easy. Through extensive search, the technical scheme which is the same as the technical scheme of the invention is not found.

Detailed Description

Example 1:

as shown in fig. 1-5, a device for removing the dead bullet from the shell-less firearm is characterized in that: a circular arc-shaped ejector pin 2 is arranged below the tail end of a gun barrel 1, the inner arc of the ejector pin 2 faces backwards, the center of the circular arc of the ejector pin is used as a hinged point, the ejector pin is hinged on a machine box 4 through a swing arm 3 and is in rotating fit, a return torsion spring 5 is arranged, the ejector pin rotates upwards around the hinged point, the head end of the ejector pin is upward, the ejector pin penetrates through the pipe wall at the bottom of the gun barrel in front of a cartridge chamber 1a and keeps a certain distance with the cartridge chamber, the pipe wall penetrates into a gun barrel chamber 1b (figure 1), the head end of the ejector pin is connected with an ejector convex bamboo shoot 6, the ejector convex bamboo shoot is a section of a cone, the small end of the ejector pin is connected to the front lower part of the ejector pin and is obliquely embedded into the inner wall of the cartridge chamber to be in movable fit, and the part protruding out of the inner wall of the cartridge chamber is milled to form an upper side surface 6a (figure 2) which is the same as the circular arc surface of the inner wall of the cartridge chamber; a truncated cone-shaped pit matched with the bullet pushing convex bamboo shoot is correspondingly formed in the inner wall of the chamber; under the action of the return torsion spring, the bullet-pushing convex bamboo shoots are normally in a state of being embedded into the gun barrel, point to the top end of the bullet of the outcropping shell-free bullet 7 in the bullet chamber towards the back upper side, and the upper side surface of the bullet is aligned with the circular arc surface of the inner circle of the chamber, so that the integrity of the inner wall of the chamber is ensured without influencing shooting. When shooting, the truncated-cone-shaped bullet-pushing convex bamboo shoots cling to the truncated-cone-shaped pits on the inner wall of the chamber, and can generate strict sealing on gunpowder gas; when a dummy bullet appears in the bullet chamber, the rear pull handle 8 enables the rear seat of the frame 9 to be in place (figure 3), the push rod is pushed upwards by a hand to rotate upwards around the hinged point of the push rod, the push convex bamboo shoot is driven to rotate towards the entrance direction of the bullet chamber (figure 4), the head end of the push convex bamboo shoot contacts the top end of the bullet head of the dummy bullet, the dummy bullet is pushed to move backwards until the push convex bamboo shoot rotates to the entrance of the bullet chamber, the bullet chamber is pushed out by the dummy bullet (figure 5), then the hand is loosened, and the push rod and the push convex bamboo shoot reset under the action of the reset torsion spring. The device has simple structure and light weight, can not only remove the dumb ammunition without shell ammunition, but also can remove the dumb ammunition of a combustible cartridge ammunition, has the same appearance and lower strength, and can not remove the dumb ammunition by adopting the existing means.

Example 2:

as shown in fig. 6-10, according to the device for removing the dummy ammunition of the caseless shell firearm described in embodiment 1, the head end of the ejector pin 2 is inserted into the barrel chamber 1b (fig. 6) by passing upward through the tube wall of the barrel bottom located in front of the chamber 1a and close to the chamber, the head end is connected with an ejector pin 6, the ejector pin is a truncated cone, the small end is connected with the ejector pin forward and downward and is obliquely embedded into the inner wall of the chamber for movable fit, the part of the ejector pin protruding from the inner wall of the chamber is milled to form an upper side surface 6a same as the arc surface of the inner wall of the chamber, and the part of the ejector pin protruding from the front end surface of the chamber is cut off to form a head end surface 6b (fig. 7) aligned with the front end surface of the chamber; the corresponding opening on the inner wall of the chamber is provided with a truncated cone-shaped pit matched with the bullet-pushing convex bamboo shoot, the lower side of the front end face of the chamber is also provided with a notch matched with the end face of the bullet-pushing convex bamboo shoot, and the rest structures are as described above. The bullet-pushing convex bamboo shoots are embedded into the gun barrel at ordinary times, the upper side faces of the bullet-pushing convex bamboo shoots are flush with the circular arc face of the inner circle of the chamber, the integrity of the inner wall of the chamber is guaranteed, the head end face of the bullet-pushing convex bamboo shoots and the front end face of the chamber are flush, the bullet-pushing convex bamboo shoots abut against the lower side of the front end face of the embedded shell-free bullet 10 in the chamber, and the integrity of the front end face of the chamber is guaranteed. When a dead bullet appears in the bullet chamber (figure 8), the rear pull handle 8 enables the rear seat of the machine frame 9 to be in place (figure 6), the bullet pushing rod is pushed upwards, the bullet pushing convex bamboo shoots rotate towards the entrance direction of the bullet chamber, the head end faces of the bullet pushing convex bamboo shoots contact and push the head end faces of the dead bullet to move backwards (figure 9) until the bullet chamber is pushed out (figure 10), and the bullet pushing rod and the bullet pushing convex bamboo shoots reset after the hands are loosened.

Example 3:

as shown in the figure: 11. 12, according to the embodiment 1, the swing arm 3 of the device for removing the dead shell of the shell-less shell firearm is connected with a guy cable 11, the guy cable is connected backwards with the head end of a longitudinal pull rod 12, the pull rod is positioned below the root of the handle 8 and is movably connected with the case 4, the back side of the root of the handle is provided with an elastic arched poking piece 13, the lower edge of the elastic arched poking piece in the free state is slightly higher than the upper edge of a protruding part 12a which is upward at the tail end of the pull rod (fig. 11). When a dummy bullet appears in the bullet chamber (figure 11), a rear pull handle 8 enables a machine frame 9 to be at the rear, meanwhile, a thumb presses a flat poking piece to enable the lower edge of the flat poking piece to move downwards and is lower than the upper edge of the protruding part of the tail end of the pull rod, when a poking piece random handle moves backwards, the thumb presses the protruding part of the tail end of the pull rod behind the flat poking piece, the pull rod and the pull rope are driven to move backwards together, the pull rope pulls a swing arm to enable a bullet pushing rod to rotate upwards around a hinge point of the bullet pushing rod, and the bullet pushing convex bamboo shoots are driven to push the dummy bullet to move towards the entrance direction of the bullet chamber until the dummy bullet is pushed out of the bullet chamber (figure 12); when the machine frame is re-advanced, the pull rod and the pull rope are loosened, and the spring pushing rod and the spring pushing convex bamboo shoot are reset under the action of the reset torsion spring. By adopting the measures, the dumb bomb can be synchronously removed when the handle is pulled backwards, and the action is convenient and natural.
