The installation support comprises a supporting board, wherein the supporting board is connected with a floor board through a guide rail and is connected with a flat board through a horizontal guide groove; a seat board is connected with the lower end of a machine gun support through the flat board; an oblique guide rail is connected with the flat board through a cylindrical piece; a U-shaped piece is connected with the oblique guide rail through a transition piece; and the lower surface of a handle is in threaded connection with the U-shaped piece, and the upper surface of the handle is welded and provided with a clamping piece of a cabin door machine gun. Compared with the prior art, the installation support provided by the utility model has the characteristics that the applicability is strong, the generality is good, the structure is simple, the operation is easy, and the like.
Description
Technical field
The utility model relates to the airplane design field, relates in particular to a kind of helicopter hatch door machine gun mounting bracket.
Background technology
Helicopter hatch door machine gun is that machine gun is installed on the helicopter, is used for the ground enemy being implemented to attack on the helicopter of flight.Because its cost is little, alerting ability is high, advantages of simple structure and simple, has all obtained good application at home and abroad on the helicopter.Existing hatch door machine gun is to be fixed on the floor by column, and its regulatory function is to realize by the ball pivot on the column.The machine gunner adopts the semi-crouch formula in the operation, causes that it is difficult to handle reposefully the hatch door machine gun on the helicopter in motor-driven, long-time manipulation easily causes fatigue, and it is abundant not to regulate the machine gun pitching, the Level tune angle that obtain by ball pivot.
The utility model content
The technical problems to be solved in the utility model: design a kind of helicopter hatch door machine gun mounting bracket, be suitable for different passenger cabin size helicopters, have preferably pitching and Level tune angle, can guarantee the long-time steadily manipulation of chaufeur.
The technical solution of the utility model: a kind of helicopter hatch door machine gun mounting bracket, comprise stay bearing plate, be connected with the floor by guide rail; Stay bearing plate is connected with dull and stereotyped by horizontal guide slot; Seat board is connected with machine gun bearing lower end by dull and stereotyped; Oblique guide rail is connected with dull and stereotyped by columnar member; U-shaped spare is connected with oblique guide rail by transition piece; Handle lower surface and U-shaped spare are spirally connected, the holder of handle upper surface welded and installed hatch door machine gun.
The beneficial effects of the utility model: the characteristics such as compared with prior art, a kind of helicopter hatch door of the utility model machine gun mounting bracket has that applicability is strong, commonality good, simple in structure, easy operating.

Fig. 1 is a kind of helicopter hatch door of the utility model machine gun mounting support structure schematic diagram.
Fig. 2 is the utility model horizontal guide slot structural representation.
Fig. 3 is the utility model holder structural representation.
Fig. 4 is the utility model guide rail connection diagram.
Fig. 5 is the dull and stereotyped annex map of the utility model.
The specific embodiment
Shown in accompanying drawing 1～5, this kind helicopter hatch door machine gun mounting bracket base portion comprises stay bearing plate 3, and in order to support level guide groove 4 and machine gun support upper end, it is to be connected with floor 1 by guide rail 2.Horizontal guide slot is in order to realize the rotation in the horizontal direction of machine gun support.Seat board 6 is taken a seat in order to the machine gunner, and it is to be connected with machine gun bearing lower end by dull and stereotyped 5.Oblique guide rail 8 reaches up and down side-to-side movement in order to what realize the machine gun support, and has guaranteed that this support can satisfy the installation of different size passenger cabin; It is to be connected with dull and stereotyped 5 by columnar member 7.Hatch door machine gun 11 rotates up and down along the axis of U-shaped spare 10, and U-shaped spare is to be connected with oblique guide rail by transition piece 9.The hatch door machine gun is to be connected on the machine gun support by holder 12, and the machine gunner is by handle 13 to the manipulation of machine gun support.
The length of guide rail is by the decision of passenger cabin size, and it is by the embedding nut on the floor and the screw on the guide rail with being connected of floor, is to add part braking roll 20 by machine with being connected of stay bearing plate.Have tapped bore on the stay bearing plate, be convenient to be connected with braking roll; Stay bearing plate can adopt Type of Welding with being connected of horizontal guide slot, also can adopt the form of being spirally connected.Horizontal guide slot contains guide groove 14 and articulated joint 15; The guide groove closed at both ends, the arc length degree is determined by the angle that horizontally rotates of hatch door machine gun design; Articulated joint upper end band is by screw thread, installs the nut of screwing on behind the flat board, and the hatch door machine gun just can be done around this hinge the rotation of certain angle in horizontal extent like this.Be welded with structure 22 on the flat board, foot-operated for the chaufeur conduct; Dull and stereotyped is to lean on pipe 21 with being connected of panel seat, wherein has tapped bore on the panel seat.The pipe lower end has outside thread, and the upper end has negative thread.The panel seat size determines according to Human physiology; Have four holes on it, after inserting for pipe, connect with screw.Columnar member lower end and three angle section welding, angle section and flat board can weld, and can be spirally connected; There are three perforates the upper end, for being connected with oblique guide rail.Oblique guide rail has several adjustment holes, and transition piece can be done up and down and move forward and backward along adjustment hole together with other mechanism on it.U-shaped spare is the axle that leans on a certain size size with being connected of transition piece; One end of axle is connected with spring reset mechanism, and the other end is fixed by bearing pin or bolt and self lock nut; The hatch door machine gun is done to rotate up and down around this axle, reverts to horizontality under the normality.Handle and U-shaped spare are fixed by bolts and nuts, with being connected of holder can be by angle section or directly fix with bolts and nuts.Holder comprises support 16, in order to supporting and to raise the hatch door machine gun, thus convenient operation; Boss 17 is threaded on it; Same screwed handle 18 extruding blocks 19, thus reach the fixedly purpose of hatch door machine gun 11.Fixing in order to ensure hatch door machine gun and holder also can in addition perforate on support, with further fixing hatch door machine gun.
