Description

The invention relates to equipment for spear fishing and is a pneumatic gun. A pneumatic weapon for spearfishing is known, containing a barrel, a harpoon, a pneumatic accumulator, coaxially disposed with a barrel, a casing, but not attached to a pneumatic accumulator mounted on the handle and mounted in the handle l. A disadvantage of the known device is the complexity of its design, due to the large number of parts and the need for their accurate fit during assembly. It is also known to have an air rifle for spearfishing, which contains a barrel with a piston placed inside it, a harpoon casing, a pneumatic accumulator, a muzzle box and a trigger mechanism 2. However, this device is characterized by the complexity of the design, due to the presence of the mechanism for locking the harpoon spaced apart in the barrel and the trigger mechanism installed in the handle, and insufficient safety of operation caused by the possibility of the stop-plate latching off the harpoon tip during its charging. The aim of the invention is to improve the safety of operation of the gun and simplify its design. The goal is achieved by the fact that in a pneumatic gun for spearfishing, we will keep the barrel with a piston inside it, a harpoon, a casing, a pneumatic accumulator, a muzzle and a trigger mechanism installed in the handle, the piston is equipped with a pusher with a flexible sleeve and boom mounted on its shaft. , connecting pusher with piston, and the casing is made movable in axial and angular directions ... On 4 "g. 1 shows a pneumatic gun in the position of the parts before charging, a general view; in fig. 2 - position of parts

shotgun before firing; in fig. 3 - the position of the parts of the gun after the shot.

The pneumatic gun for underwater contains a casing 1, in the front part of which water holes are drilled, and in the back part protrusions are made for closing with shaped grooves, a pneumatic accumulator 2 having figured grooves on a smaller outer diameter, and on the end face a device for filling 10 gun with compressed air (not shown), orut the end of the barrel 3 is hermetically connected to the pneumatic accumulator 2, and the other end has a narrowing restricting the movement of the piston 4 within the barrel 3. The piston 15 is rigidly connected to the push rod 5 and pusher 6 imekzhtsim seamed inside the elastic sleeve 7. The gun also includes a sear 8, the trigger 9, 20 of depreciation pro- clutch 10, muzzle 11, {harpoon 12 and a handle (not shown).

The gun works as follows.

In the position of the parts shown in FIG. 1, moving the piston 4, 25 of the push rod 5 and the push rod 6, rigidly connected to each other, is limited to the sear 8. The abutment end of the pneumatic accumulator 2 in or on the thigh, and holding the casing with both hands 1 relative to the barrel 3 in the direction of the pneumatic accumulator 2, until the projections of the casing 1 fall into the shaped grooves of the pneumatic accumulator 2, pos. Before that, the cover 1 is rotated in an arc 35 of compression relative to the pneumatic accumulator 2, connecting these parts together. With the axial movement of the casing 1 piston 4, rod thickness. The driver 5 and the pusher 6 are carried away in 40 motion relative to the barrel 3 by the sear 8 mounted on an axis in the handle of the gun. The piston 4, moving inside the barrel 3, compresses the air in the pneumatic accumulator 2. After that, the trigger 5 hook 9, the gun is put on a safety device, and a harpoon 12 is inserted into the casing 1, the refined shank of which is to prevent the gun is pinched in the hole at the elastic sleeve 7 of the pusher 6. The gun is ready to fire.

For a shot, the trigger 9 is pressed. The sear 8, which interacts with the trigger, goes down and releases the nausea 6. Under the pressure of compressed air, the piston 4, the pusher bar 5 and the pusher 6 move forward sharply, pushing the harpoon 12 out of the casing 1 and pushing the gun. The pusher 6 in the stroke stroke hits the depreciation pad 1O. In order to load the gun once more, it is necessary to remove pneumatic accumulator 2 from engagement with casing 1, pull pneumatic accumulator 2 until the pusher 6 takes the position shown in FIG. 1. Then the cycle repeats.

The proposed pneumatic gun for spearfishing is simpler in design, since it has fewer seals, there is no locking mechanism in the muzzle box, there is no rigid rod between the muzzle bottle and the handle, the gun is not provided with a rigid support plate for charging the gun. In addition, it has a higher operational safety compared with the known rifles, since there is no harpoon in the rifle at the moment of charging.
