[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-7 This utility model provides a quick-release cartridge case collection mechanism for machine guns, comprising a mounting rail 1, a movable clamping block 2, and a U-shaped mounting bracket 3. The mounting rail 1 has a wavy groove 4 inside, and the top of the inner wall of the U-shaped mounting bracket 3 has a device groove 5. A clamping mechanism is installed inside the device groove 5, which works in conjunction with the wavy groove 4 to clamp the U-shaped mounting bracket 3. A knob 7 is fixedly connected to the end of a rotating shaft away from the locking bolt 8 and mounted on the mounting rail 1. A fixing clamping block 6 is fixedly connected to the bottom end of the mounting rail 1. A rotating shaft is rotatably mounted inside the mounting rail 1, and one end of the rotating shaft is fixedly connected to the locking bolt 8. A cartridge case collector 9 is fixedly connected to one end of the U-shaped mounting bracket 3. The movable clamping block 2 is positioned relative to the locking bolt 8. A threaded hole 10 is provided at the position of bolt 8. The movable clamping block 2 is threadedly connected to the outer surface of the locking bolt 8 through the threaded hole 10, and the top of the movable clamping block 2 contacts the bottom of the mounting slide rail 1. Through the cooperation of the fixed clamping block 6, the movable clamping block 2, the locking bolt 8 and the threaded hole 10, the mounting slide rail 1 can be clamped and fixedly installed on the ammunition belt clamp, preparing for the convenient installation of the subsequent cartridge case collector 9. Through the cooperation of the wavy groove 4, the U-shaped mounting bracket 3 and the clamping mechanism, the cartridge case collector 9 can be quickly and conveniently clamped and installed on the mounting slide rail 1, so as to use the cartridge case collector 9 to collect the cartridge cases ejected from the ejection port, avoiding the cartridge cases from flying around and damaging the precision instruments on the armored vehicle or interfering with teammates.

[0028] Anti-slip rubber blocks 11 are fixedly connected to the opposite sides of the fixed clamping block 6 and the movable clamping block 2. By providing anti-slip rubber blocks 11 on the fixed clamping block 6 and the movable clamping block 2, the friction between the clamping block and the clip on the spring chain can be increased, thereby improving the stability of the mounting slide rail 1 clamped on the clip on the spring chain and preventing the mounting slide rail 1 from loosening and falling off.

[0029] The clamping mechanism includes a pressing rod 12 movably installed inside the device slot 5. A clamping spring 13 is fixedly connected between one end of the pressing rod 12 inside the U-shaped mounting bracket 3 and the inner wall of the device slot 5. A clamping block 14 is fixedly connected to the bottom end of the pressing rod 12, and a pressing block 15 is fixedly connected to one end of the pressing rod 12 outside the U-shaped mounting bracket 3.

[0030] The cartridge case collector 9 uses a cartridge case collecting net, and the bottom of the cartridge case collecting net is equipped with a zippered discharge port for easy discharge of the cartridge cases collected in the net.

[0031] The cartridge case collector 9 uses a cartridge case guide cover, with a cartridge case guide channel at one end to transport the collected cartridge cases to an external collection container for unified collection.

[0032] Working principle: During installation, first place the mounting slide rail 1 on top of the ammunition belt clamp of the Type 201 machine gun, so that the fixed clamping block 6 is located on one side of the ammunition belt clamp. Then, the top of the movable clamping block 2 contacts the top of the end of the mounting slide rail 1 away from the fixed clamping block 6, so that the threaded hole 10 on the movable clamping block 2 is aligned with the locking bolt 8. Then, turn the knob 7 to drive the rotating shaft and the locking bolt 8 to rotate. Under the limiting effect of the mounting slide rail 1 on the movable clamping block 2, it cannot rotate. Then, it moves along the axis of the locking bolt 8 to the side closer to the fixed clamping block 6. With the cooperation of the fixed clamping block 6 and the movable clamping block 2, the mounting slide rail 1 is clamped and fixedly installed above the ammunition belt clamp without damage, preparing for the convenient installation of the subsequent cartridge case collection part 9.

[0033] When the cartridge case collector 9 needs to be installed on the mounting rail 1, the user holds the U-shaped mounting bracket 3 and movably places it over the outside of the mounting rail 1. Then, the pressing block 15 is pressed towards the side close to the U-shaped mounting bracket 3, which in turn compresses the clamping spring 13 through the pressing rod 12, putting it into a compressed state and storing energy. The movement of the pressing rod 12 also moves the clamping block 14 away from the wavy groove 4, so as to adjust the position of the U-shaped mounting bracket 3. When the cartridge case collector 9 moves to the position of the ejection port of the Type 201 machine gun... When the cartridge case collector 9 is positioned opposite each other and fully covers the ejection port, the pressing block 15 is released. The spring force of the clamping spring 13 drives the clamping block 14 to move, so that the clamping block 14 abuts against the wave-shaped groove 4. The U-shaped mounting bracket 3 is clamped and installed on the mounting slide rail 1 by the cooperation of the clamping block 14 and the wave-shaped groove 4, thereby realizing the quick and convenient installation of the cartridge case collector 9. After installation, the bottom end of the cartridge case collector 9 is located above the charging handle of the Type 201 machine gun, so as not to affect the user's normal pulling of the charging handle.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
