RU2558162C2 - Multi-barrelled shooting module - Google Patents

Abstract

FIELD: weapon and ammunition.

SUBSTANCE: invention relates to weapon equipment, namely to multi-barrelled shooting modules. The module contains an assembly of barrels, a slapper-and-trigger mechanism with a housing and a slapper. The slapper is installed on a rod which can perform a forward rotary motion. The rod guides a combat spring. Coaxially to the rod a bushing with a screw groove is installed. The rod is fitted with a ledge interacting with the screw groove of the bushing. The bushing and the rod are installed in free-wheeling couplings, external rings of which are rigidly fixed in the housing of the slapper-and-trigger mechanism, and internal ones rotate unidirectionally. The combat spring is clamped between two stoppers so that it resists to the progression of the rod in two directions, keeping an intermediate position of rest.

EFFECT: reduction of dimensions and weight of the weapon, design simplification and, as a result, reliability improvement.

Description

The invention relates to the field of weapons technology and can be used in samples of small arms.

Known multi-barrel firing module containing a block of trunks for equipment with cartridges, a node for locking the channels of the barrel, equipped with electrocapsules, and a contact group. The shot is carried out by applying an electrical signal through the contact group to each electrocapsule. When the electrocapsule is triggered, the energy of its powder gases initiates the cartridge capsule (RF Patent No. 2310805 of July 26, 2006).

The disadvantage of this design is the use of an additional element of equipment - an electrocapsule, which complicates the process of supplying ammunition, complicates the loading procedure and increases the cost of each shot, which is especially critical for multi-barrel weapons.

The closest analogue of the present invention, selected as a prototype, is a device that is a four-barrel self-cocking pistol containing a barrel block, a trigger mechanism with a hammer mounted on a longitudinal axis with discrete rotation, and a housing with a handle. The drummer is mounted on a guide rod, which simultaneously serves as the guide rod of the mainspring and the axis of rotation of the hammer, and is fixed in the housing. The shock mechanism is made in the form of spring-loaded strikers. On a spring-loaded striker screw grooves are made, communicating with each other in the form of a continuous pattern. Inside the drummer, a compression spring is placed on its axis. Rebound springs are placed on each striker. A pivot lock interacting with the profile grooves of the striker is installed in the gun body (US patent No. 3260009 class. 42-69 dated 12/23/1964).

The disadvantages of such a device are that the placement of rebound springs on each striker requires an increase in the dimensions and mass of the strikers and weapons in general; screw grooves, communicating with each other in the form of a continuous pattern, complicate the manufacture of the hammer, require additional structural elements that prevent the rotation lock from sliding along the grooves in the wrong direction, which complicates the design of the device as a whole and, as a result, reduces its reliability and increases the complexity manufacture. These disadvantages are especially apparent when designing a device with a large number of trunks, for example, 10 or more.

The objective of the invention is to reduce the size and mass of weapons, simplifying the design and, as a result, improving reliability and reducing the complexity of manufacturing.

To solve the problem in a multi-barrel firing module containing a block of barrels, a trigger mechanism with a body and a striker mounted on a guide rod, capable of translational-rotational movement and serving as a guiding spring of the mainspring, new according to the invention is that it is coaxial to the rod the drummer has a sleeve with a screw groove, the rod of the drummer is equipped with a protrusion interacting with the screw groove of the sleeve, the sleeve and rod of the drummer are installed in overrunning couplings, uzhnye rings are rigidly fixed in the housing of the trigger, and the inner rotating in one direction, the action spring is clamped between the two stops so that the translational motion of the rod resists impactor in two directions, keeping the rest position in the intermediate position.

The drive ensuring the operation of the device is an electromagnet, the rod of which is connected with the rod of the striker.

The invention is illustrated by drawings, where:

figure 1 shows a multi-barrel firing module, ready for use;

figure 2 shows the cocking of the trigger mechanism;

figure 3 shows the moment of production of the shot.

The proposed multi-barrel firing module contains a barrel unit 1, a trigger mechanism 2 with a body 3 and a drummer 4. The drummer is mounted on the rod 5. A mainspring is located on the rod 6. A sleeve 7 with a screw groove 8 is aligned with the rod, and the rod is provided with a protrusion 9, meshing with the groove of the sleeve. The sleeve is installed in the overrunning clutch 10, and the shaft is installed in the overrunning clutch 11. The outer rings of both overrunning clutches are rigidly fixed in the trigger housing, and the inner rings can only rotate clockwise when viewed from the rear. The mainspring is sandwiched between the stops 12 and 13 so that the firing pin is not brought to its extreme forward position at rest. The drive for triggering the trigger mechanism is an electromagnet 14, the anchor 15 of which is connected to the rod.

The operation of the device is as follows. For firing a shot, an electromagnet 14 is turned on. Anchor 15 moves backward in direction A, moving the rod 5. The rod, in turn, draws a stop 12 into compression, which compresses the mainspring 6. During backward movement, the protrusion 9 of the rod moves along the screw groove 8 bushings 7, turning the striker 4 in direction B by angle B and installing it opposite the barrel G. Bush 7 tends to turn in the opposite direction, but is kept from turning by overrunning clutch 10. After cocking, the electromagnet 14 is disconnected and the mainspring 6, being released, accelerates the rod 5 and the striker 4 forward in the direction D by means of the stop 12. When the moving parts reach their initial position, they gain maximum speed and continue to move forward by inertia, compressing the mainspring in the opposite direction by means of the stop 13. As a result of this movement, the striker 4 reaches its extreme forward position and a shot occurs, after which the mainspring returns the rod with the hammer to an intermediate position. When moving forward, the protrusion 9 of the rod 5, interacting with the groove 8, rotates the sleeve 7 in the direction E, thereby preparing the trigger mechanism to produce the next shot. When moving forward, the rod tends to turn in the opposite direction, which is prevented by the overrunning clutch 11.

Thus, the invention provides:

- reducing the dimensions and mass of the weapon by eliminating the release springs on each striker;

- simplifying the design and, as a consequence, increasing reliability and reducing the complexity of manufacturing by introducing standard overrunning clutches instead of the striker with grooves of a complex continuous pattern and additional structural elements that prevent the rotation lock from sliding along the grooves in the wrong direction.
