When the manual insurance 1 is in the shooting position, the hammer 3 is shooting When the back seat of the bolt hits the hammer, it rotates clockwise backward from the vertical position under the action of the external force, and the compression amount of the hammer spring 4 increases when the hammer 3 rotates clockwise backward from the vertical position. The reserve energy is provided for the hammer 3. Forward rotation force.
[0054] The safety process of the manual safety device based on the hammer-type firing pistol of the present invention is as follows:
[0055] figure 1 When the manual insurance 1 is in the post-shooting position, the safety tooth 301 on the hammer is stuck on the iron blocking tooth 202 on the iron block, and the hammer 3 is in the firing position at this time. The upper end of the hammer spring 4 is pressed against the bottom of the hammer spring mounting hole 305 of the hammer, and the lower end is in contact with the disc 501 on the hammer spring rod. The ball crown 502 on the hammer spring rod rests on the hammer spring seat. On the spherical surface 602, the safety limit tooth 601 on the hammer spring seat is stuck to the safety positioning groove 103 on the manual safety. At this time, if the operator manually applies a clockwise force to the hammer 3, the hammer 3 will move forward. Rotating clockwise, the barrier iron 2 tends to rotate clockwise under the action of the barrier spring 8. The linkage teeth 302 and single-acting teeth 303 on the hammer squeeze the barrier iron 2 in turn; when the hammer 3 rotates to the hammer When the linkage teeth 302 of the hammer are higher than the iron teeth 202 on the barrier iron and the single-acting teeth 303 on the hammer are lower than the iron teeth 202 on the barrier iron, the operator cancels the clockwise force acting on the hammer 3, The hammer linkage tooth 302 on the hammer will jam the iron blocking tooth 202 on the blocking iron, and the hammer 3 is in the linkage ready-to-fire position at this time. When the hammer 3 rotates until the single-acting tooth 303 on the hammer is higher than the iron-blocking tooth 202 on the iron block, the operator cancels the clockwise force acting on the hammer 3, and the single-acting tooth 303 on the hammer will The iron blocking tooth 202 on the blocking iron is stuck, and the hammer 3 is in the single-action ready to be fired position at this time. The appeal action realizes that when the manual insurance 1 is in the shooting position, the hammer 3 stays in the firing position, the linkage waiting position, and the single-action waiting position.
[0056] in figure 1 The manual safety 1 in the position shown is turned clockwise to figure 2 , Figure 3a , Figure 3b In the position shown, the safety limit tooth 601 on the hammer spring seat is stuck on the inclined surface 105 behind the safety positioning slot 103 on the manual safety, and the anti-iron safety tooth 101 on the manual safety is stuck to the anti-iron limit on the anti-iron Teeth 201, the iron-barrier teeth 202 on the barrier iron block the safety teeth 301 on the hammer when the hammer is in the firing position; the iron-barrier teeth 202 on the barrier iron block the linkage teeth 302 of the hammer when the hammer is in linkage The position to be fired; when the iron stop tooth 202 on the stop iron jams the single-acting tooth 303 of the stuck hammer, the hammer is in the single-acting position to be fired; the hammer 3 is subjected to a single rightward action due to falling, scratching, etc. After the force is applied, the barrier iron 2 cannot be squeezed open, and the hammer 3 cannot be rotated clockwise; the barrier iron 2 alone cannot be squeezed open by the leftward force of the barrier iron safety teeth 101 on the manual insurance, and the barrier iron 2 cannot be rotated counterclockwise. At the same time, the barrier 2 also restricts the counterclockwise rotation of the hammer 3. The appeal action realizes the three-state safety function of the hammer 3 in the firing position, the linkage to be fired position, and the single action to be fired position.
[0057] Such as Figure 4 , 5 , 6 shows that when the single-acting tooth 303 on the hammer is stuck on the iron-barrier tooth 202 on the iron-barrier, the hammer spring 4 is in the maximum compression state. If the operator briefly applies a clockwise direction to the manual insurance 1 The function of the iron stopper limit tooth 201 is squeezed open by the hammer release tooth 102 on the manual insurance to make the iron stopper 2 rotate counterclockwise, the iron stopper tooth 202 on the iron stopper and the single-acting tooth 303 on the hammer Separate, the hammer 3 will rotate counterclockwise under the force of the hammer spring. After rotating a certain angle, the safety release tooth 304 on the hammer contacts the hammer limiting tooth 104 on the manual insurance, and the hammer 3 drives the manual insurance 1. Rotate clockwise, the blocking iron 2 rotates clockwise under the action of the blocking iron spring 8. When the hammer 3, the safety 1, and the blocking iron 2 rotate to Image 6 In the position shown, the safety release tooth 304 on the hammer 3 is separated from the hammer limit tooth 104 on the manual fuse 1, and the fuse limit tooth 601 on the hammer spring seat 6 is gradually jammed into the fuse positioning slot 103 for manual fuse Positioning makes the manual safety 1 rotate to the shooting position, and the linkage tooth 302 on the hammer is stuck on the iron blocking tooth 202 on the blocking iron 2. The above action can be used to rotate the manual insurance 1 to safely release the hammer 3 when there is a bullet in the breech of the pistol and the hammer 3 is ready to be fired to realize the function of releasing the hammer 3 from being fired. During the whole process, the rotation of the hammer 3 is restricted by the hammer limiting tooth 104 on the manual insurance, which can ensure the safety of the pistol during the shooting process.
