Description

The utility model relates to the field of armament, namely to boxes for cartridge strips.

According to GOST 28653-90, for automatic small arms with fully automated reloading, a cartridge box and cartridge strip are used as an element to ensure the functioning of automatic small arms for firing and storing ammunition (cartridges).

The cartridge box of a machine gun is a box for placing small arms cartridges loaded into a cartridge belt fed from it when firing at a machine gun. The cartridge belt of a machine gun is a belt with sockets for placing small arms cartridges or cartridges connected to each other by flexible links.

A cartridge box for automatic small arms is known, which contains an ammunition compartment made of a metal body with side walls, a bottom and a hinged lid with a hinged valve. On the opposite side of the housing from the lid flap there is an additional receiving compartment for used cartridge strip. The receiving compartment is made of fabric material and is fixed to the body of the ammunition compartment using an upper guide frame and a lower support bracket (invention patent RU 2793990).

The well-known cartridge box provides the ability to fire from a machine gun and accept spent cartridge strips, increases the rate of fire during reloads and eliminates interference with the movement of a soldier. At the same time, the cartridge box is represented by a metal body, which is characterized by metallic noise when the cartridges collide with the box lid, i.e. when moving, it unmasks a serviceman with noise from the impact of cartridges with a metal body, especially at night. In addition, under mechanical influence (a fall from a height, heavy objects falling on it), it loses its original shape, and, therefore, is characterized by insufficiently high combat survivability of the box under external influence.

A known box for cartridge tape contains a metal body with side walls and a bottom; inside the metal body there is a tab made of soft elastic material adjacent to the walls and bottom of the box, and the tab is fixed in the body by means of T-shaped protrusions located on it that fit into the through slots on the side walls of the case, and the width of the slots is less than the wide part of the protrusions themselves (invention patent RU No. 2512790).

The well-known cartridge box allows for quick laying of the cartridge strip due to the design possibility of tilting the entire lid of the box, and also provides the ability to fire a machine gun from the box. The disadvantage of this design is that the box itself is represented by a metal case, and to reduce the metallic sound, an insert made of soft elastic material is additionally installed in the box, which is attached to the case using special fasteners, which increases the number of components required during assembly, and, consequently, the weight cartridge box. In addition, the known cartridge box does not exclude metallic noise when cartridges collide with the box lid, i.e. does not completely eliminate the risk of unmasking a serviceman, and with mechanical impact on the cartridge box there is a high risk of loss of the original shape (jamming of individual parts of the body and other deformation), and, therefore, the cartridge box may be completely or partially unsuitable for firing a machine gun from the box, i.e. .e. complete or partial loss of combat survivability of the box.

The technical objective of the claimed utility model is to increase the efficiency of operating a cartridge box in combat conditions by maintaining the ability to quickly lay the cartridge strip and fire from the box while simultaneously increasing the combat survivability of the cartridge box under external influence and reducing the factor of unmasking a serviceman by eliminating metallic noise from the impact of cartridges with the walls of the box.

The technical result is to increase the operating efficiency of the cartridge strip box in combat conditions due to:

- reducing the unmasking factor when moving a serviceman by eliminating the metallic sound when cartridges collide with the walls of the box;

- ensuring the preservation of the shape of the cartridge box when the machine gun with the box falls onto the ground or a hard surface for the possibility of firing “from the box”

- reducing the weight of the cartridge box.

The technical task is achieved in that the box for the cartridge belt contains a body with a window for the cartridge belt, the case has a neck with a lid, side and end walls and a bottom, two hooks and a latch are mounted on the lid for mounting on a machine gun bracket, characterized in that the window for The cartridge belt is made with a folding flap, consisting of two upper and lower sections spring-loaded relative to each other, connected by a hinge, at the ends of which there are axle shafts, and the lower section is additionally hinged to the body, the ribs of the side walls are equipped with support hooks, into which they are inserted in the closed position axle shafts of the hinge, the body is made of elastically deformable plastic and equipped with stiffening ribs, the neck of the body along the perimeter is permanently connected to the lid, which is made of hard plastic.

Any rubber-like polymer can be used as an elastically deformed plastic, for example polyethylene, polypropylene, maflex, which are suitable for casting and molding.

Any material suitable for these purposes can be used as a rigid plastic for the manufacture of the lid, for example, reinforced thermoplastic plastic, in particular, polyamides of grades RA-6, RA-6,6 RA-4.10 (fiberglass 50%), volgamid grades PA6- GF30 (30% fiberglass), PA-B3T7 (impact-resistant), POKETON brand polyketone (M330A), Maskon POM13 brand polyacetal, polystyrene (30% butadiene) and other similar materials that provide high rigidity and strength to the lid. The lid may be manufactured by casting or molding by any known methods.

To further increase rigidity, the neck of the body can be made thicker during the casting of an elastically deformable material, or it can be additionally reinforced with a perforated metal strip pressed into the neck along its perimeter.

The lid is permanently connected to the neck of the body, for example, by means of metal rivets installed around the perimeter, ensuring structural rigidity. The permanent connection of the cover to the body can be made by any known methods.

The box for the cartridge strip on the walls of the case is equipped with vertical stiffeners, which are made in the form of thickenings along the height of the case. The corners of the body are also made thicker along the height of the body, serving as stiffening ribs. The bottom of the body is equipped with horizontal and vertical stiffeners.

The box for the cartridge strip is additionally equipped with a carrying handle made, for example, of fabric material.

The window for the cartridge strip is made on the end wall of the housing with a folding flap. The upper section of the folding flap has left and right side protrusions, and the ribs of the side walls adjacent to the said end wall are equipped in the upper part with reciprocal grooves in which the said side protrusions are placed in the closed position and are designed for gripping with the hand and opening the upper section.

The flap is made of elastically deformable plastic, with the ability to open in the direction opposite to the latch hooks located on the lid. The end wall is preferably made beveled, which makes it possible to make a window for the cartridge strip of the largest possible area.

A comparison of the proposed technical solution with the prototype shows that it differs in the following features:

-the window for the cartridge strip is made with a folding flap;

- the flap consists of two upper and lower sections spring-loaded relative to each other;

- the upper and lower sections are connected to each other by a hinge, at the ends of which there are axle shafts;

- the lower section is additionally hinged to the body;

- the ribs of the side walls are equipped with support hooks, into which the hinge axles are inserted in the closed position of the end wall;

- the body is made of elastically deformable plastic;

- the body is equipped with stiffening ribs;

- the neck of the body is rigidly connected to the lid along the perimeter;

- the cover is made of hard plastic.

Therefore, we can assume that the claimed utility model meets the “novelty” criterion.

The utility model can be manufactured using known equipment, so it meets the “industrial applicability” criterion.

Figure 1 schematically shows the inventive box for cartridge strip, main view, Figure 2 also shows a side view, Figure 3 shows the inventive box in isometry with a window for cartridge strip, closed by a hinged flap on the end wall, Fig. Fig. 4 shows a model sample of the inventive box with an open upper section of the flap; Fig. 5 shows a model sample of the inventive box with a fully open flap; Fig. Figure 6 shows the inventive box, rear view. Figure 7 shows the inventive box with a loaded cartridge strip, the end of which is extended in the direction of the hooks with a latch on the lid.

The box for cartridge tape contains a body 1 made of elastically deformable plastic, namely maflex by casting with a neck 2, on which a cover 4 made of hard plastic, for example polyamide, is installed using rivets 3. The housing 1 has side walls 5.6 (Fig. 2), end walls 7.8 and a bottom 9. To increase the strength of the connection of the neck 2 with the lid 4, the thickness of the neck 2 of the housing along the entire perimeter is greater than the thickness of the side walls 5.6 of the housing (by not shown in the figure). The end wall 7 contains two spring-loaded sections 10 relative to each other, the upper 11 and lower 12 sections of the flap, which performs the function of a window behind the cartridge strip (Figure 2). Sections 11, 12 are connected by a hinge 13, at the ends of which there are axle shafts 14 and 15, and the lower section 12 is connected to the body 1 by means of an additional hinge 16 (Fig. 3). In the middle part of the ribs of the side walls 5,6 there are support hooks 17, 18 In the closed position of the end wall 7, the axle shafts 14, 15 are inserted into support hooks 17,18 (Fig. 5) on the corresponding ribs 27 and 28 of the side walls 5 and 6. On the upper section 11 there are side projections 19, 20, which in the closed position placed in grooves 23 and 24 located on the edges of the side walls 5 and 6 and are designed to grip the upper section 11 with the hand when opening the flap. To increase rigidity, the body 1 and the bottom have stiffening ribs 21. The box for the cartridge belt is equipped with a belt 22 for carrying the cartridge box.

In the initial position, the box for the cartridge strip is located with the window for the cartridge strip on the end wall 7 open (Fig. 5). In this position, the upper section 11 and the lower section 12 of the flap are moved away from the body 1 by means of an additional hinge 16. The cartridge strip is loaded into the open window, and the free end of the cartridge strip is left outside the box in the direction of the lid 4 (Fig. 7) in close proximity to the hooks 25 with a latch 26, placed on the cover 4 and for attaching the box to the machine gun bracket, which are made of metal. In order to close the box, it is necessary to rotate section 12 on an additional hinge 16 and insert the axle shafts 14,15 into the support hooks 17,18. After this, rotate the upper section 11 on the hinge 13, and since it is spring-loaded relative to the lower section 12, it fits tightly to the free end of the cartridge strip and to the body 1.

In order to open the inventive box, it is necessary to pull the side projections 1920 towards you, removing them from the grooves 23 and 24, rotate the upper section 11 around the hinge 13, and continue rotating the section, while the axle shafts 14, 15 come out of the support hooks 17, 18. Next, both sections rotate on an additional hinge 16. The box with the sections removed from the body (open flap) is brought into position as shown in Fig.5.

The design feature of the proposed box is as follows. When a soldier moves, the cartridges collide with the walls of the box. If the box is made of metal, then it makes metallic sounds that unmask the soldier. In the claimed technical solution, the box body is made of elastically deformable plastic, so when the cartridges collide with the walls of the box, a muffled sound is produced. The following should also be noted. In combat conditions, the survivability of the box ensures offensive or return fire. If a machine gun falls on the ground or stones, if necessary, or a soldier is injured, or when landing from a parachute, the metal box may become deformed and become unsuitable for firing. In addition, when the metal box is deformed, cartridge strips, including those made of plastic, can be damaged, which deprives the soldier of the opportunity to return fire even if he manages to remove cartridge strips from the deformed box. Failure to fire can lead to the death of a soldier or unit and failure to complete the combat mission. In the claimed box, the material from which its body is made is elastically deformable, therefore, after a collision with cartridges or mechanical impact, the box restores its shape (“springs back”) and allows firing from a machine gun. To ensure the shaping of the box, the lid is made of hard plastic. The applicant, during various tests of the box, found that in the event of a strong collision of the cartridge box with the ground, the body can be torn off from the cover in the neck area, therefore, in order to strengthen it when manufactured by casting, it is better to strengthen the neck by thickening the wall of the neck, and make the connection of the box with the cover permanent, for example, using rivets, which significantly increases the rigidity of the box structure. Since in the design of the inventive box the lid is permanently connected to the neck of the body along its perimeter using rivets, for refilling the cartridge strip there is an end wall, which contains two sections spring-loaded relative to each other, hingedly connected to each other, while both the upper section and and a lower section, together with the upper section, forming a large area in the window for laying the cartridge strip, which makes it possible to quickly lay the cartridge strip. At the same time, the sections spring-loaded with each other provide the possibility of unhindered exit of the cartridge belt during firing through the upper edge of the upper section, i.e. in close proximity to the hooks with a latch, located on the cover and intended for attaching the machine gun. Since the inventive box is made of elastically deformable material and with a lid made of hard plastic, after possible external influences and deformations it confidently holds its shape and allows the soldier to fire “from the box”, which was also confirmed by fire tests, and also significantly lightens the box , because The weight of a plastic box is less than the weight of a similar metal box.

Thus, the inventive box for cartridge strip ensures an increase in the efficiency of operation of the box for cartridge strip in combat conditions by reducing the unmasking factor when moving a soldier by eliminating the metallic sound when cartridges collide with the walls of the box, preserving the shape of the box when the machine gun with the box falls on the ground or a hard surface due to the elastic properties of the body, the ability to fire “from the box” while simultaneously reducing the weight of the cartridge box, which plays a significant role in a combat situation.
