Abstract

The invention relates to methane projectiles with and without the use of warheads, and in particular to triggers of underwater weapons. The purpose of the invention is to increase the safety of weapons in operation by eliminating the possibility of triggering of trigger 2 in the atmosphere. The trigger mechanism of the underwater weapon contains a trigger 1, the first 4 and second 8 pistons with rods 3 and 9, respectively, placed in cylindrical holes 5 and 10, communicating with each other, and a whisper 11 connected to the rod 9. placed in the housing 6. The channels 5 are made in the hole 5. For firing a shot, it is necessary that the cavity of the hole 5 is filled with water that flows through the drain holes 7. In the absence of water in the hole 5, air is compressed by the piston 4, the pressure force of which is insufficient to overcome the resistance laziness of the spring 13 and movement of the piston 8 with the rod 9 and the sear 11.1 zp f-ly, 2 ill.

Description

Fig 2

The invention relates to methane projectiles with and without the use of warheads, namely, triggers for underwater weapons.

There is known a spearfire firearm containing a trigger mechanism and a shutter in the form of a glass, the walls of which are made of windows, while the receiver has safety holes located so that when the shutter is in the extreme position they are aligned with the windows in shutter 1.

The disadvantage of these weapons is the lack of protection against firing in the atmosphere.

Known trigger mechanism for underwater weapons containing a housing, a spring-loaded trigger mounted in it, a spring-loaded rotary whisper with a cock, and a piston with a rod located in a cylindrical bore of the housing with through drain channels 2.

The disadvantage of the prototype is that it does not provide complete protection against the production of unauthorized shots in the atmosphere, which adversely affects the safety of weapons in operation.

The purpose of the invention is to increase the safety of weapons in operation by eliminating the possibility of triggering the trigger in the atmosphere.

For this, in a trigger mechanism comprising a housing, a spring-loaded trigger mounted therein, a spring-loaded rotary whisper with a cocking cock and a piston with a rod placed in a cylindrical bore of the housing with through drain channels, a second cylindrical hole in communication with the first cylindrical hole is made in the housing, the mechanism is equipped with a second piston with a rod installed in the second cylindrical bore of the housing, the rotary whisper pivotally connected to the rod of the second piston, and the trigger oic hook is formed with a shank and shank mounted in this first cylindrical housing bore with a reciprocating movement therein and is connected to the rod of the first piston, wherein the drainage channels are arranged between the first and second pistons. In addition, the mechanism is also equipped with a “finger”, which is fixedly mounted with the housing, while on the rod

the first piston has a longitudinal groove under the finger.

In FIG. 1 shows the trigger of an underwater firearm

figure 2 - trigger underwater spring weapons.

The trigger mechanism consists of a trigger 1 with a spring 2 connected to the rod 3 of the first piston 4. Last

0 is placed in a cylindrical hole 5 of the weapon body 6. In the cylindrical hole 5, through drain channels 7 are made connecting the inner cavity of the cylindrical hole 5 with the external medium 5. The second piston 8 with the rod 9 is installed in the second cylindrical bore 10 in communication with the cylindrical bore 5. The diameter of the second piston 8 is calculated depending on

0 of the diameter of the first piston 4, the trigger pull of the first and second pistons and the force required to move the sear 11 The sear 11 is mounted on the axis 12 sec

5 is rotatable, spring-loaded by spring 13 and pivotally connected to stem 9.

A restrictive groove 14 is made in the rod 3, in which the pin 15 is placed. It is rigidly fixed in the housing 6.

In the trigger mechanism of a submarine firearm, a sear 11 is held by a spring-loaded trigger 16.

The trigger mechanism of underwater weapons5 works as follows.

Before the shot, water, due to the presence of through drain channels 7, is located in the cavity of the cylindrical hole 5. To fire the shot, press

0 on the trigger 1. In this case, the piston 4. moving along the cylindrical hole 5, begins to squeeze out water 1, through the drain channels 7. until it blocks them. With further pressure on the trigger

5, hook 1 will begin to move the second pore 8 with the rod 9, turning the sear 11 on the axis 12. When using the trigger in firearms, the sear will release the trigger 16, which, having hit

0 brisk, will make a shot. In a spring weapon, a sear 11 releases a harpoon 17. which, under the action of a war spring, is ejected from the barrel.

When finding underwater weapons EI

5 there is no water in the atmosphere in the cavity of the cylindrical hole 5, since it flows out through the drain channels 7. When you press the trigger 1, the air leaves the drain channels until they are blocked by the piston 4 and then starts to compress. Odnaks ol

the trigger is limited by the length of the groove 14 and is designed so that the pressure force of the compressed air on the piston 8 is insufficient to overcome the resistance of the spring 13 and move the piston 8 with the rod 9 and the sear 11 A shot in the atmosphere will not occur.

Thus, this trigger mechanism of underwater weapons provides high operational safety and is universal, i.e. it can be used in spring (pneumatic) and firearms underwater weapons
