Abstract

FIELD: weapons and ammunition.

SUBSTANCE: pneumatic arms comprises a barrel and a magazine with a seat to locate a bullet. The magazine is equipped with a ledge, the lower surface of which has a fixing section, representing a part of a circumference, the diametre of which is equal to the external diametre of the breech barrel part, and the centre matches the centre of the magazine seat circumference. The lower surface of the magazine ledge is also equipped with a section having a shape of radius surface, the centre of which is a pin. The pin is installed in the magazine slot installed as capable of rotation relative to the pin and longitudinal displacement within the slot, where the spring is installed. The spring presses the magazine with the lower surface of the ledge to the breech part of the barrel.

EFFECT: higher accuracy of fire, elimination of deformation and increased bullet speed.

Description

The invention relates to weapons technology, in particular to pneumatic weapons with a magazine for bullets.

Known multi-charged airguns (patent No. 2235264, class. F41B 11/00, RU), in which the store, comprising a housing and a cartridge for bullets, is spring loaded with a latch made in the form of a two-armed lever, one shoulder of which interacts with the cartridge, and the second with clip in which the store is inserted.

Known pneumatic weapons (patent No. 2092767, class F41B 11/00, RU), taken as a prototype, containing a barrel, a bolt with a rammer made in the form of a stepped rod, a feed mechanism, including a clip (magazine) with sockets for bullets and with a gear comb interacting with a spring-loaded latch, made in the form of a two-shouldered lever, and with a rammer. The teeth of the comb comb carry out the orientation of the bullet relative to the barrel channel, and a spring-loaded latch ensures that the clip is fixed in a certain position.

A disadvantage of the known pneumatic guns is that their design does not provide high accuracy of the orientation of the bullet when it is sent to the barrel relative to the axis of the barrel. A sufficiently long chain of displacements of interacting parts during the preparation and production of a shot makes it possible to skew the bullet when it is sent to the barrel, which leads to an increase in resistance to the movement of the bullet, to its deformation. As a result, the stability of the initial bullet’s flight speed decreases and, accordingly, the accuracy of fire decreases.

The objective of the claimed invention is to increase operational characteristics, in particular accuracy of fire, by eliminating the possibility of deformation of the bullet and increasing the stability of the initial velocity of the bullet.

The problem is solved due to the fact that in a pneumatic weapon containing a barrel and a magazine with a slot for placing a bullet, the magazine is equipped with a protrusion, the lower surface of which has a fixing section representing a portion of a circle whose diameter is equal to the outer diameter of the breech of the barrel, and the center coincides with the center of the circumference of the magazine’s nest, and a section having the shape of a radiused surface, the center of which is a pin placed in the groove of the magazine, which can be rotated relative to the pin and longitudinal nnnogo movement within the groove in which the spring is installed, pressing the store with the lower surface of the protrusion to the breech.

Using the claimed invention will improve the reliability and accuracy of sending a bullet into the barrel. The direct connection of the bullet socket with the barrel (without intermediate links) increases the accuracy of their alignment and, therefore, ensures the reliable supply of bullets to the barrel without distortions and deformations, which increases the stability of the initial speed of the bullet and the accuracy of fire.

The claimed invention is illustrated by drawings, which depict:

figure 1 - pneumatic weapons, General view;

figure 2 - section aa in figure 1, the position of the store before sending the bullet into the barrel;

figure 3 - section aa in figure 1, the position of the magazine before loading the bullet into the magazine slot.

Airgun contains a barrel 1 (figure 1) and a magazine 2 with a slot 3 (figure 3) for placing a bullet (not shown). Shop 2 (figure 2) is mounted to rotate relative to the pin 4, placed in the groove 5 of the store 2, and with the possibility of longitudinal movement within the groove 5. Shop 2 is equipped with a protrusion 6 (figure 3), the lower surface of which has a fixing section 7 representing a part of a circle whose diameter is equal to the outer diameter of the breech 8 of the barrel, and the center coincides with the center of the circle of the nest 3 of the store 2 (figure 2), and a section 9 having the shape of a radius surface, the center of which is the pin 4. In this case, in the groove 5 stores 2 posted spring 10, pressing the magazine 2 with the lower surface of the protrusion 6 to the outer surface of the breech 8 of the barrel 1. Magazine 2 has a protrusion 11, with which the user rotates the magazine 2 (counterclockwise) relative to the pin 4, and the protrusion 12 (figure 3) to rotate magazine 2 in the opposite direction (clockwise).

Airgun works as follows. When exposed to the protrusion 11 (figure 2) in the direction of the arrow, the magazine 2 rises, compressing the spring 10 and deactivates the surface of the fixing section 7 of the magazine ridge 6 with the breech 8, rotates around the pin 4 and takes the socket 3 away from the barrel ( figure 3) to accommodate the bullet.

After loading the bullet into the slot 3, the magazine is rotated to its original position by acting on the protrusion 12 in the direction of arrow C. During the rotation, the magazine with the surface of the section 9 having the shape of a radiused surface, the center of which is pin 4, slides over the surface of the breech 8 of the barrel. Upon reaching the fixing section 7, the magazine 2 (figure 2) under the influence of the spring 10 moves downward, fixing relative to the breech 8 of the barrel.

Claims (1)

Airgun containing a barrel and a magazine with a slot for placing a bullet, characterized in that the magazine is equipped with a protrusion, the lower surface of which has a fixing section representing a portion of a circle whose diameter is equal to the outer diameter of the breech of the barrel, and the center coincides with the center of the circle of the magazine’s nest, and a portion having the shape of a radiused surface, the center of which is a pin placed in a groove of a magazine mounted to rotate relative to the pin and longitudinally move to the limit ah groove, in which a spring is installed, pressing the store with the lower surface of the protrusion to the breech.
