Description

no fake drum

technical field

The utility model belongs to an ammunition feeding device for firearms, in particular to an ammunition drum without false ammunition.

Background technique

With the increase in the firepower requirements of individual automatic weapons in modern warfare, the infantry squad's demand for large-capacity drums has gradually emerged. In the industry, individual weapons with good firepower such as light machine guns have even appeared to replace the automatic rifles currently equipped in large quantities. Replacing individual weapons in such a large number not only brings disastrous consequences to logistics, but also lacks economy. At present, the main bomb feeding methods of the drum are as follows: (1) The scroll spring is used to drive the drum whose axis coincides with the drum shaft to pick the drum. This feeding method has fewer bullets and a smaller feeding capacity. ;(2) Elastic chain drum, the bullets are placed on the metal elastic chain, and the elastic chain is curled in the metal drum shell, which is actually a chain feeding method, which requires two people to use Cooperate, one person lifts the ammunition chain and one person shoots, which is inconvenient to use; (3) C-type drum, divided into two separate drums on the left and right, each drum can hold about 40-45 rounds, and the two drums can be used for more than 40 rounds. The single-row method will form a double row, entering the vertical bomb inlet part, and the bombs are powered by the scroll springs in the two drums, but 10-20 dummy bombs ranging from 10 to 20 rounds are required.

Detailed ways

A drum without false bullets, which includes a drum shell 1, a vertical support plate 2, a vertical support plate spring 3, a front ratchet 4, a push arm 5, a center shaft 6, a track arm 7, a rear ratchet 8, a push The arm bomb 9, the pin 10 and the fixed bottom cover, the two sides of the drum shell 1 are C-shaped drums, the middle is a vertical bomb supply chamber 13, the C-shaped drum and the vertical supporting plate spring chamber 13 are integral, and the drum shell 1 The inner opening push arm track 11 is arranged on the wall of the C-shaped drum, and the vertical support plate slot 12 is arranged on the two side walls of the vertical support spring chamber 13; the C-shaped drums on both sides are respectively provided with front ratchets 4. Push arm 5, center shaft 6, track arm 7, rear ratchet 8 and push arm spring 9, release hook 15 is arranged on push arm 5, push arm spring 9 is arranged at the end of push arm 5, push arm 5 is set On the small round hole 16 of the front ratchet 4, the track arm 7 is arranged on the central shaft 6, and the bolt passes through the central hole of the front ratchet 4, the central shaft 6, and the rear ratchet 8 to connect with the C-shaped drum; the vertical supporting plate spring chamber 13 is provided with a vertical support spring plate 2 and a vertical support spring plate spring 3, and the vertical support spring plate 2 is connected with the vertical support spring plate spring 3 by a hook;

The left and right sides of the vertical support spring plate 2 are provided with vertical support plate buckles 14, and the vertical support spring plate 2 is provided with an arc groove, the radius of curvature of the arc groove is the same as the radius of curvature at the bottom of the shell of the push arm bullet 9. same.

The vertical bracket buckle 14 is made of elastic steel sheet.

The parts in the described C-shaped drum are mostly made of high-strength engineering plastics and aviation aluminum alloys.

As shown in Figure 1, when the vertical bomb supply chamber 13 is filled with bullets, the spring support plate 2 is pressed to the bottom of the vertical bomb supply chamber, and the vertical support plate buckle 14 is automatically buckled with the vertical spring support plate slot 12, Implement locking. At this moment, the two feed openings blocked by the push arm bullet 9 on the push arm 5 arranged on the front ratchet 4 become movable parts, and the bullet is provided by the shape of the support spring plate 2 to divert the force to both sides, so that the bullet Enter the C-shaped drum. Thus, the loading process in the C-shaped drum begins. The bullet sequence moves along the inner wall of the arc-shaped drum under the pressure of the bullet inlet, and at the same time compresses the scroll spring to store energy. When the end position of the C-shaped drum is pressed, the loading is completed. When feeding bullets, the bullets cooperate with the ratchets on the front ratchet 4 and the rear ratchet 8, and are arranged in double circles inside the housing. Under the effect of the rotational torque provided by the spiral springs connecting the front ratchet 4 and the rear ratchet 8, the front ratchet 4 and the rear ratchet 8 rotate and feed bombs. When all the bullets in the C-shaped drum are supplied, the bullet supply openings on both sides will be blocked by the push arm bullet 9, and the release hook 15 will be released from the vertical lock of the vertical bullet supply chamber 13 along the push arm track 11 of the inner opening. The supporting plate buckle 14 releases the vertical support spring 3 of the vertical feed chamber 13, and now the last bullet has entered the vertical feed chamber 13, and the vertical feed chamber 13 is formed by the vertical feed chamber 13 inner wall, the push arm The bullet 9 and the spring support plate 2 form a closed vertical bullet supply route, and its structure is similar to that of the magazine. At this point, the vertical spring support plate spring 3 connected with the spring support plate 2 starts to work, pushing the remaining bullets in the vertical bullet supply chamber Move toward the feed port until it is pushed out of the drum by the machine gun.

As shown in Figure 7, the drum is in the feeding state, and the remaining bullets in the drum are 15 rounds.

As shown in Figure 8, the magazine is in the feeding state, and the remaining bullets in the drum are 13 rounds. 1 bullet 2 enters the vertical bullet feeding chamber 13, and all the bullets in the C-type magazine body have been shot. At this time, the push arm 5 The release hook 15 on the top slides along the inner opening push arm track 11 to the vertical support plate slot 12, triggers the vertical support plate buckle 14 on the vertical support plate 2, and releases the vertical support plate. Close the bomb supply port of the casing to form a closed vertical bomb supply space. At this time, the vertical spring support plate 2 is free, and the vertical spring support plate 2 is pushed upward by the vertical spring support plate 2 to continue feeding bombs.

As shown in Figure 9, the drum is in the feeding state, and the remaining bullets in the drum are 11 rounds. At this time, the vertical spring support plate 2 has carried out a stroke of an bullet position upwards under the promotion of the vertical spring support plate spring 3, and has Push the bullets 12 and 13 in Fig. 6 out of the drum.

As shown in Figure 10, the drum is in the feeding state, and the remaining bullets in the drum are 2 rounds. Now the vertical support spring 3 is close to the maximum relaxation state in the drum, and the vertical support spring 2 is pushed to the drum supply opening part, and the bullet 2 is in the state of waiting to enter the chamber.
