Description

one

This invention relates to the field of snorkeling.

Known hydropneumatic guns for submarine hunting include a barrel with a harpoon, a chamber for seawater, a piston, a lever, a trigger, and a handle. However, the placement of the center of gravity in front of the handle and the need to turn the cocking lever forward to set the shooting mechanism on the combat platoon reduce the accuracy and strength of the gun and degrade the performance of the gun.

The purpose of the invention is to increase bo accuracy and improve the performance of the gun.

For this purpose, the proposed rifle was fitted with a trigger mechanism in a slider, placed in a hollow body with CANNOT grooves and articulated by means of an axis and a short arm of a cocking lever fixed to the body.

FIG. 1 shows the proposed gun, the position of the parts after the shot; in fig. 2 - the same, the position of the parts when cocking the lever; in fig. 3 the same, the position of the parts before the shot.

Claims (1)

The shotgun contains a chamber 1 for outboard WATER, into which a piston 2 is placed with c-sealing rings 3 and a stem 4 terminating in TAIL 5. The chamber 1 is plugged with a sleeve 6 fitted with rings 7 for sealing the stem and a ring 8 for sealing the working volume of the chamber. The hollow body 9c is screwed into the sleeve 6 with two longitudinal grooves. In the housing 9, there is a shear-knot assembly consisting of a slider 10 and a sear 11. The lever 12 of the platoon is attached to building 9. The short arm of the lever. 13 and 13 is pivotally connected to the slider. The axis 14 passes through the longitudinal grooves in the housing 9 and CROSSING the transverse hole in the slider 10. The trigger mechanism also has a trigger lever 15, connected by a pull 16 with the trigger 17, located in the handle 18. Tg 16 is covered with a protective casing 19, the breech of the barrel 20 is enclosed in a cylindrical casing. 21, in which the distance adjustment device 22 is located. The range adjustment of the bo is carried out by changing the area of the windows in the wall of the barrel, intended for the exit of water. An axial bore with a check valve is made in the piston rod to fill the gun with compressed air before using the chamber. To place the rifle on a platoon, it is necessary to withdraw the platoon lever 12 to the rearmost position (see FIG. 2). In this case, the slider 10 moves forward in the housing 9 and the sear 11 drops over the stem of the stem 5 of the rod 4. When the lever 12 is moved to the initial position (see Fig. 3), the slider moves to the extreme rear position with the piston. During the movement of air in the blotch space, chamber 1 is compressed. At the same time, the chamber space in front of the piston is filled with seawater. There are holes in the wall of the latter to exit the air displaced when the chamber is filled. Shotgun ready to shoot. When the trigger 17 is pressed, the piston 2 is released and moves forward under the action of compressed air, pushing the harpoon out of the barrel with the pressure of water in the chamber. Claims Hydropneumatic speargun, soy & barrel with a harpoon, seawater chamber, piston, cocking lever, trigger and grip, characterized by the fact that in order to improve the accuracy of the bo and improve performance, the gun in it whispered The trigger mechanism is installed in a slider, placed in a hollow body with through grooves and pivotally connected by an axis and a short arm, with a cocking lever, reinforced, on the body "N Have
