Embodiment 1

[0083] A machine gun self-positioning sliding seat for military helicopters is documented, such as figure 1 shown, it includes:

[0084] seat base 1;

[0085] The sliding seat 2 is provided with a sliding guide rod 3; one end of the sliding guide rod 3 is fixedly connected with the sliding seat 2, and the other end is rotatably connected with the positioning seat 4 through a hinge structure to guide The sliding seat 2 is driven and slidably arranged on the seat base 1 along the arc guide track;

[0086] The machine gun frame 5 is rotatably arranged on the positioning seat 4 for fixing the machine gun;

[0087] The positioning mechanism includes: a first positioning hole 6 arranged on the sliding guide rod 3, a second positioning hole 7 arranged on the seat base 1 and matched with the first positioning hole 6, and A positioning pin 8 that is slidably arranged in the first positioning hole 6 and is inserted into the second positioning hole 7 ; side and at the central positio...

Embodiment 2

[0099] A machine gun self-positioning sliding seat for military helicopters is described, comprising:

[0100] seat base 1;

[0101] Sliding seat 2, the sliding seat 2 is provided with a sliding guide rod 3; one end of the sliding guide rod 3 is fixedly connected with the sliding seat 2, and the other end is connected with the positioning seat 4 through a hinge structure to guide The sliding seat 2 is driven and slidably arranged on the seat base 1 along the arc-shaped guide track;

[0102] The machine gun frame 5 is rotatably arranged on the positioning seat 4 for fixing the machine gun;

[0103] The positioning mechanism includes: a first positioning hole 6 provided on the sliding guide rod 3, a second positioning hole 7 provided on the seat base 1 and adapted to the first positioning hole 6, and The positioning pin 8 that is slidably arranged in the first positioning hole 6 and is mated with the second positioning hole 7; side and is located at the central position in th...

Embodiment 3

[0106] The difference between this embodiment and embodiment 1 is that, as Figure 4 As shown, the positioning seat 4 includes: a fixed base plate 12, a rotating column 13 fixedly arranged on the fixed base plate 12; The rotating column 13 is sleeved and connected in rotation; the pop-up airbag 9 is embedded in the side of the collar 15 close to the sliding guide rod 3 . The pop-up airbag 9 is an annular cylindrical airbag matching the shape of the sliding guide rod 3 .

[0107] In this embodiment, the collar 15 is provided with an accommodating groove for accommodating the pop-up airbag 9, and the pop-up airbag 9 is bonded to the wall of the accommodating groove; When the pop-up airbag 9 is inflated, the pop-up airbag 9 overcomes the adhesive force and moves out of the accommodating groove.

Abstract

A machine gun automatic positioning sliding seat for military helicopters, comprising: a seat base; a sliding seat, a sliding guide bar is arranged on the sliding seat; The first positioning hole on the sliding guide rod, the second positioning hole that is arranged on the seat base and matches the first positioning hole, and the positioning hole that is slidably arranged in the first positioning hole and mated with the second positioning hole pin; the first positioning hole is arranged on the side of the sliding guide rod close to the positioning seat and is located at the central position of the sliding guide rod in its width direction; a collision protection mechanism. The above-mentioned structure solves the problem that the rotation angle of the rotating gun frame in the prior art is relatively small, cannot meet the shooting requirements at a large angle, and requires the operator to realize the angle rotation by himself, which affects the shooting accuracy.

Description

technical field [0001] The invention relates to the technical field of aircraft machine gun supporting mechanisms, in particular to a machine gun automatic positioning sliding seat for military helicopters. Background technique [0002] Military helicopters need to set up machine guns at the warehouse door during flight, and fighters sit on the machine gun seat in the cabin and turn the position to attack targets outside the cabin. The machine gun auxiliary equipment of the existing military helicopter usually achieves attacks on targets from different angles outside the cabin of the military helicopter by arranging a rotating gun mount for fixing the machine gun. However, the above-mentioned rotating gun mount has the following problems: 1. The rotation angle is small, and it cannot meet the shooting requirements of a larger angle under the condition that the position of the aircraft remains unchanged. 2. When shooting the target through the above-mentioned rotating gun st...
