The purpose of the invention is realized as follows:
a single-row magazine supporting plate structure comprises a supporting plate body,
the upper end surface of the bullet supporting plate body is an inclined plane with a high front part and a low back part, and the middle part of the upper end surface of the bullet supporting plate body is longitudinally provided with an arc groove which is used for being matched with the surface of a bullet to form surface contact;
the lower end face of the bullet supporting plate body is a plane and is used for being matched with the bullet supporting spring;
the front end of the bullet supporting plate body extends downwards to form an arc head, the rear end of the bullet supporting plate body is provided with a limiting plate extending downwards, chamfers are formed between the limiting plate and the outer side surface of the bullet supporting plate body to form an arc tail, the arc head and the arc tail are used for enabling the bullet supporting plate body to rotate in the magazine, and the arc head is used for being matched with the bullet holding opening to limit the bullet supporting plate body;
the spring support spring plate is characterized in that a groove used for accommodating the end of the first ring of the support spring is horizontally arranged between the limiting plate and the inner side surface of the spring support plate body, a boss is arranged in the middle of the lower end surface of the spring support plate body, and a hole used for inserting the head of the support spring is formed in the boss.
Preferably, the rotation angle of the projectile body in the magazine is greater than 15 °.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
the bullet supporting plate is reliably connected with the bullet supporting spring, the installation and the disassembly are simple and quick, the bullet supporting plate is positioned left and right in the magazine and can be turned over front and back according to the bullet supply requirement. The bullet supporting plate has the characteristics of simple structure, remarkable effect and the like, and is widely suitable for the bullet supporting plate design of various gunneries.
Drawings
FIG. 1 is a schematic view of a magazine construction;
FIG. 2 is a schematic structural view of the elastic supporting plate of the present invention;
FIG. 3 is a view taken along line A of FIG. 2;
fig. 4 is a view from direction B of fig. 2.
Detailed Description
Referring to fig. 1, a schematic diagram of a magazine structure is shown, wherein: 1-cartridge body; 2-supporting the elastic plate; 3-support spring; 4-magazine bottom cover.
Referring to fig. 2-4, the magazine supporting plate structure of the single-row magazine comprises a magazine supporting plate body, wherein the upper end surface of the magazine supporting plate body is an inclined plane with a high front part and a low rear part, and an arc groove is longitudinally arranged in the middle of the upper end surface of the magazine supporting plate body and is used for being matched with the surface of a bullet to form surface contact; the lower end face of the bullet supporting plate body is a plane and is used for being matched with the bullet supporting spring; the front end of the bullet supporting plate body extends downwards to form an arc head, the rear end of the bullet supporting plate body is provided with a limiting plate extending downwards, chamfers are formed between the limiting plate and the outer side surface of the bullet supporting plate body to form an arc tail, the arc head and the arc tail are used for enabling the bullet supporting plate body to rotate in the magazine, and the arc head is used for being matched with the bullet holding opening to limit the bullet supporting plate body; the spring support spring plate is characterized in that a groove used for accommodating the end of the first ring of the support spring is horizontally arranged between the limiting plate and the inner side surface of the spring support plate body, a boss is arranged in the middle of the lower end surface of the spring support plate body, and a hole used for inserting the head of the support spring is formed in the boss.
The spring supporting plate is provided with a groove H1 for accommodating the spring support, a hole phi matched with the spring support is added, the head of the spring support is inserted into the hole, and the first ring of the spring support is clamped into the groove H1, so that the spring supporting plate is not easy to separate from the spring support; in addition, the length direction of the bullet supporting plate is provided with an arc groove R3 and an angle alpha, so that the bullet shell can be well attached; in addition, the front end of the bullet supporting plate is provided with a large arc (arc head) R2, so that the bullet head end of the bullet supporting plate can be turned over at a large angle (at least 15 degrees) which is similar to the bullet bottom end as the center of a circle in the magazine according to the requirement of a bullet feeding route; the rear end of the bullet supporting plate body is provided with an arc tail (the rear end of the bullet supporting plate body is provided with a limiting plate extending downwards, the limiting plate and the outer side surface of the bullet supporting plate body are chamfered to form the arc tail) R1, R2 is more than 2 times of R1, and R1 has the function of avoiding the interference between the bullet supporting plate and the inner wall of the magazine when the bullet supporting plate is turned up and down by taking the bullet bottom end of the bullet supporting plate as a circle center; the straight line section below the R1 ensures reliable vertical translation and positioning of the bullet supporting plate in the magazine; and the arc head (with the height of H3) is blocked by the bullet embracing opening when no bullet exists in the magazine, so that the bullet supporting plate can be prevented from escaping from the bullet embracing opening, and the bullet supply reliability is ensured.
In actual work, the height H2, the width H4 and the length L of the boss where the insert supporting spring hole is positioned can be adjusted according to the space of the supporting spring; in the B-direction view, R3 and H5 can be adjusted in size according to the size of the cartridge case.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
