Abstract
The utility model relates to a bracing rod, and belongs to the design technique of airplane structures. The bracing rod comprises a hinge support seat, a sliding rail, an angle section and a quick-release pin, wherein the hinge support seat is of a single-lug structure; the sliding rail is of a flat plate structure, one end of the sliding rail is of a double-lug structure, a rail groove is formed in the central line of the flat plate in the length direction, and a location hole is formed in the top of the rail groove; a through groove for mounting the quick-release pin by a sliding pin bolt mounting hole is formed in the angle section, the double-lug structure of the sliding rail is connected with the single-lug structure of the hinge support seat in a matching manner, a pin bolt can move along the rail groove in the sliding rail through the sliding pin bolt mounting hole in the angle section and the rail groove in the sliding rail, an opening is formed at the topmost end of the sliding rail, a steel wire rope passes through the hole, and the quick-release pin is tied to the top of the sliding rail through the steel wire rope. The bracing rod can be designed according to the structure of a specific covering cap, the sliding rail of the bracing rod can be used for fixing the bracing rod after the covering cap is closed, the space of the interior structure of an airplane is not occupied, and special fixing devices do not need to be designed; the bracing rod is machined by adopting sheet metal parts and sheet materials, and is light in weight and low in cost.
Description
Technical field
The invention belongs to aeroplane structure design technology, be specifically related to a kind of servo-actuated hinge strut.
Background technology
General lid strut is mostly chosen existing finished product or standard component, and structurally arrange that proprietary fastening devices fixes strut, the advantage of this strut can directly be chosen exactly in standard component handbook or finished product catalogue, only need to design corresponding fastening devices, and design work amount is little; Shortcoming is exactly that this class strut has corresponding specification, cannot according to design idea, choose completely, is exactly secondly that this class strut need to reserve corresponding space and is fixed, and the weight and the cost that are exactly in addition this class strut are all higher.
Summary of the invention
The object of the invention is: aircraft maintenance lid (not separation-type lid) is after opening, all need to be fixed support, this servo-actuated hinge strut has solved safeguards that lid opens the problem of rear fixed support, this strut is the unlatching campaign along with lid by the slide rail that carries, by Quick-release pin, locate, need not take interior of aircraft structure space; After lid closure, strut moves to initial position, nor needs on aircaft configuration, to design the fastening devices of strut again, can save interior of aircraft space; This strut assembly is selected sheet metal component and sheet material machining, and lightweight, cost is low.
Technical scheme of the present invention is: a kind of strut, it is characterized in that, and comprise rocker bar bearing, slide rail, angle section, Quick-release pin; Rocker bar bearing is monaural structure, and slide rail is slabbed construction, and one end is ears structure, on dull and stereotyped length direction center line, has rail groove, and a locating hole is set on rail groove top; On angle section, process sliding pin installing hole, the groove of Quick-release pin is installed, slide rail ears structure is connected with the monaural respective outer side edges of rocker bar bearing, pin is by the rail groove on sliding pin installing hole and slide rail on angle section, can slide along the rail groove on slide rail, in the perforate of slide rail top, by this hole of steel wire penetrating, and by Quick-release pin by wire rope rope on slide rail top.
The invention has the beneficial effects as follows: this strut can design according to concrete port cover structure, is not subject to the specification limits of standard component or finished product; The slide rail that this strut carries can, in lid closure afterwards for fixing strut, not take interior of aircraft structure space, again the fastening devices of design specialized; This strut adopts sheet metal component and sheet material machining, and lightweight, cost is low.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: a kind of strut, comprises rocker bar bearing, slide rail, angle section, Quick-release pin; Rocker bar bearing is monaural structure, and slide rail is slabbed construction, and one end is ears structure, on dull and stereotyped length direction center line, has rail groove, and a locating hole is set on rail groove top; On angle section, process sliding pin installing hole, the groove of Quick-release pin is installed, slide rail ears structure is connected with the monaural respective outer side edges of rocker bar bearing, pin is by the rail groove on sliding pin installing hole and slide rail on angle section, can slide along the rail groove on slide rail, in the perforate of slide rail top, by this hole of steel wire penetrating, and by Quick-release pin by wire rope rope on slide rail top.
Rocker bar bearing is fixed on body, determine the open angle of lid, the second, the movement locus coupling by the movement locus of lid and strut along rocker bar bearing, determines the position of locating hole in the length, strut of strut rail groove and the angle section installation site in lid inner side.
Fixed hinge bearing on body, as shown in Figure 1; Slide rail is connected with rocker bar bearing, as shown in Figure 2; The movement locus of the movement locus of slide rail and lid is coupled, as shown in Figure 3.In Fig. 3, when being coupled, should first lid be moved to angle θ along lid movement locus from lid initial position; Then slide rail is moved to angle section and lid joint face can be fitted with lid medial surface along slide rail movement locus; Wherein the radius of motion of slide rail is the distance of slide rail hinge point to slide rail locating hole center; The position of angle section on slide rail should guarantee that the locating hole of slide rail inserts in region at the Quick-release pin of angle section, and the sliding pin installing hole of angle section is in the rail groove of slide rail; Now angle section is the installation site of angle section in mouth covering position; During actual installation, can to the installation site of angle section, adjust by the radius of motion that changes slide rail.Just can complete thus the design and installation of this strut, Figure 4 shows that the state signal of strut when lid is closed.Fig. 5 has provided the structural representation of angle section.
