Description

The utility model relates to stopper delays, that is, to mechanisms that keep the bolt in the rearmost position when all the cartridges in the magazine are used up.

The prior art shutter bolt (Manual CK-308.RE "Saiga-308-1" self-loading hunting carbine, page 13, Fig. 09-12, published at: https://kalashnikov.com/netcat_files/ 440/666 / OM_Saiga_308_l_rus.pdf) containing a spring-loaded lever mounted in the receiver on the axis. The slide lag allows you to put the movable parts of the gun on it to facilitate the connection of the loaded magazine. To do this, move the moving parts back to the stop and drown the bolt stop lever that protrudes behind the bottom of the receiver, and holding it with your hand gently release the moving parts. After this, you should attach the equipped magazine to the gun and remove the moving parts from the stopping delay. To remove the moving parts from the slide delay, move the moving parts back to the stop and release them sharply.

The disadvantage of this design is the low practical rate of fire of the weapon due to the impossibility of automatically setting the shutter mechanism on the shutter lag in the absence of an empty magazine

The closest is the bolt delay containing a lever mounted in the receiver on the axis and protruding beyond the bottom of the receiver of the weapon, and contains the shutter associated with the lever, located inside the collection case, and the lever is installed with the ability to interact with the gun store, and the shutter stops is connected to the lever detachably and contains a spring that acts on the shutter stop and on the lever. (Patent No. 97822, IPC F41A 17/42, Shutter Latency, Application 2010110596 dated March 19, 2010, publ. September 20, 2010, Bull. 26

The disadvantage of this design is:

1. Low practical rate of fire of the weapon due to the impossibility of automatic setting of the bolt mechanism on the slide delay in the absence of an empty magazine.

2. Deterioration of the connection of the shutter and the bolt (figure 1 additional materials) due to shock in the process of setting the bolt mechanism on the bolt delay by abruptly stopping the stop stop in the bolt gate mechanism.

The purpose of the proposed utility model is to increase the practical rate of fire of the weapon and the reliability of the bolt mechanism.

The technical solution is to install an automatic slide delay.

The technical solution is carried out in the installation of a mechanism that allows the bolt mechanism to be installed on the bolt delay, even in the absence of an empty magazine when assembling weapons into the fighting position and excluding shock effects on the bolt when jamming by stopping the slide frame into the bolt delay.

The device for automatic shutter lag is illustrated by the following graphic figures:

1. Automatic slide stop mechanism.

2. Changes required in the grip.

3. Changes required in the store.

4. Setting in automatic mode on the slide delay without the store.

5. The bend of the probe under the influence of the cartridge, which is located in the established shop in the mode of the slide arrest of the weapon.

6. Removal from an automatic slide delay when installing a magazine with a cartridge, carried out by moving the slide mechanism back.

7. Removal from the automatic slide delay when installing a magazine with a cartridge by pressing the trigger of the slide stop drive.

8. Setting automatically on the slide delay when the store is empty.

9. Withdrawal from an automatic stopping delay without a magazine by pushing the trigger of the drive of the stopping delay.

18. The deformed state of the probe

The device works as follows:

1. When preparing the carbine to the fighting position (FIG. 4), it is necessary to pull the handle 3 (not shown) of the slide mechanism 3 back towards the butt (not shown), after which the slide mechanism 3 moves forward under the influence of a return spring (not shown) and groove rests on the reinforced stop slide delay 3 and stands on the slide delay. Next, a magazine 11 (figure 5) is installed with the cartridges 7, while the probe 4 is bent under the influence of the cartridge 7 upwards 18. At the same time, the removal from the bolt delay does not occur due to the friction force that occurs at the point of contact between the bolt mechanism 10 (which is under the action of a return spring ) and reinforced stop 3 levers 1.

Further, the removal from the automatic slide delay can be done in two ways:

1) Acting on the lever (not shown) of the bolt mechanism 10, retract the bolt mechanism 10 back (figure 6). When this happens out of the interaction of the bolt mechanism and reinforced stop 3. lever 1, which rotates on the axis 2 counterclockwise under the influence of elastic forces (footnote 1 *) arising from the deformation of the probe 4 and does not block the movement of the bolt mechanism 10 forward and the bolt mechanism 10 due to the recoil spring (not shown), it moves forward and sends the cartridge 15 from the magazine 11 to the weapon barrel.

2) Acting on the trigger 6 of the drive 5 automatic slide delay down (figure 7), the lever 1 is forced to turn counterclockwise on the axis 2, while the reinforced stop 3 leaves the interaction with the slide mechanism 10, which is due to the return spring (not shown) moves forward and sends the cartridge 15 from the magazine 11 to the barrel of the weapon.

2. After shooting and emptying the magazine (figure 8), the probe 4 of the lever 1 goes down into the cut in the magazine case 16 due to the action of the return spring of the automatic slide delay 9. At the same time, the slide mechanism 10 moved to the rear end position under the action of powder gases , begins to move forward under the influence of the return spring (not shown) and rests against the reinforced stop of the slide delay 3 with a groove and stands on the slide delay.

3. Next, remove the magazine (figure 9) and, acting on the trigger 6 of the actuator 5 automatic shutter delay down, the lever 1 is forced to turn counterclockwise, while the reinforced stop 3 leaves the interaction with the shutter mechanism 10, which is due to the return spring ( not shown) moves forward and moves the weapon to the transport position.

4. If it is necessary to continue further firing after the end of the cartridges in the store and automatic shutter lag, you need to remove the magazine and carry out the sequence of actions in paragraphs 1-2.

The effectiveness of the proposed utility model is to increase the practical rate of fire of the weapon and the reliability of the bolt mechanism.

one*. The force of elasticity - the force that occurs in the body as a result of its deformation and tends to return it to its original (initial) state.
