Abstract

The utility model relates to a multi-functional hinge used for the connection of aero-space, civil and other quickly removable hinge type large hatch covers and structure parts with rotation, limiting and stopping requirements in the machinery industry. The hinge comprises a support, a rotating shaft, a stop pin, a spacer pin, a slide way, a stop handle and a rotating arm; the support is in an inverted T shape; the vertical wall of the support is provided with positioning holes for the installation of the rotating shaft and the spacer pin; the spacer pin is arranged in a positioning hole; one side of the base of the support is a sloping side corresponding to an organism; the other side of the base is provided with a lug; the side of the lug is provided with a stop pin hole; a surface which is vertical to the stop pin hole is provided with the slide way and a stop slot; one end of the rotating arm is arranged on the other positioning hole of the support by the rotating shaft; and the other end of the rotating arm is fixed on a hatch cover of an airplane. The multi-functional hinge has the functions of spacing, stopping and the like, is installed in an embedded way, not only reduces the resistance of the airplane and saves the structure space of the organism, but also reduces the structure weight.

Description

Multifunctional hinge

Technical field

The utility model is used for having rotation between the mechanical components industry, the multifunctional hinge that is connected between the Aeronautics and Astronautics of spacing and stop requirement, the large-scale flap of quick-release hinge type such as civilian and the structural element.

Background technology

In airplane design, the functional requirement of the switch that general flap adopts conventional hinge hinge, brace apparatus and stopping means to wait to satisfy flap, spacing and stop.Conventional hinge hinge, brace apparatus and stopping means independently, separate; The hinge hinge mainly satisfies the rotation requirement of flap, Yi Bian be fixed on the body covering, Yi Bian on flap; Brace apparatus is after flap is opened to the position, the flap support fixation is lived, on one side it be fixed on the housing construction, Yi Bian on flap; Stopping means is that the prevention flap is opened excessive back and damaged with the airframe surface, or prevents that raceway for wiring on the flap draws situation such as bad and the flap opening angle restraint device that is provided with generally is fixed on the body surface.They are contained in the different position of housing construction respectively.This cover system is for the aircraft configuration with hyperbolic degree, and common hinge hinge is difficult to guarantee requirements such as the fairing of aircraft external surface, sealing, and strut system and stopping means will occupy the equipment component installing space, and multiple spot is installed more complicated simultaneously.

Summary of the invention

The purpose of this utility model provides and a kind ofly can guarantee requirements such as the fairing of aircraft external surface, sealing, and it is little that strut system and stopping means take up space, the easy-to-install multifunctional hinge.Technical solution of the present utility model is, hinge is made up of bearing, turning cylinder, latch, spacer pin, sliding tray and locking handle and cursor, bearing is " ⊥ " shape, has the locating hole that turning cylinder and spacer pin are installed on the vertical wall of bearing, and spacer pin places a locating hole; The base of bearing is and the corresponding hypotenuse of housing construction on one side, on the another side of base lug is installed, the side of lug has lock pin aperture, has sliding tray and back stop slot on the face vertical with lock pin aperture, communicates between lock pin aperture, sliding tray and the back stop slot three; One end of cursor is installed in another locating hole of bearing with turning cylinder, and the other end of cursor is fixed on the aircraft flap; Latch places lock pin aperture, and latch is provided with the threaded mounting hole that is connected with locking handle.Back stop slot curves downwards and places the terminal of sliding tray and communicate with sliding tray.The beneficial effect that the utlity model has is, the utility model rolls into one functions such as spacing, stop, buries installation in the hinge, can reduce aircraft drag, save the housing construction space, can alleviate construction weight again, installation and maintenance simultaneously and manufacturing are simpler, and cost is cheaper.

The specific embodiment

Hinge is made up of bearing 1, turning cylinder 2, latch 12, spacer pin 3, sliding tray 8 and locking handle 13 and cursor 10, bearing 1 is " ⊥ " shape, have the locating hole that turning cylinder 2 and spacer pin 3 are installed on the vertical wall of bearing 1, spacer pin 3 places a locating hole; Spacer pin 3 is installed on the bearing 1 by this locating hole, thereby cursor 10 is run into spacer pin 3 realization limit functions in rotation process.The base 15 of bearing 1 is and housing construction 4 corresponding hypotenuses 5 on one side, and bearing 1 is fixed on the motionless structural member such as body.

Lug 6 is installed on the another side of base 15, and the side of lug 6 has lock pin aperture 7, has sliding tray 8 and back stop slot 9 on the face vertical with lock pin aperture 7, communicates between lock pin aperture 7, sliding tray 8 and back stop slot 9 threes; One end of cursor 10 is installed in bearing 1 another locating hole with turning cylinder 2, and cursor 10 is connected with turning cylinder 2 by this locating hole, can rotate freely between cursor 10 and the turning cylinder 2.The other end of cursor 10 is fixed on the parts that aircraft flap 11 grades can open, and cursor 10 planforms can satisfy in the waterproof of flap 11 and the hinge buries function; Latch 12 places lock pin aperture 7, can horizontally slip.Latch 12 is provided with the threaded mounting hole 14 that is connected with locking handle 13, and locking handle 13 is installed on the latch 12 by the threaded mounting hole of latch 12, and scribbles anaerobic adhesive.Locking handle 13 drives latch 12 and by the sliding tray 8 of the locking handle on the bearing 1 13 latch 12 is sent in the locating hole on the other one side on the bearing 1.Back stop slot 9 communicates with sliding tray 8 at the end of travel of the sliding tray 8 of locking handle 13, and latch 12 is rotated down the back stop slot 9 of locking handle 13 being put into latch 12, prevents that latch 12 from horizontally slipping.During use,

1. flap is opened

All connectors around the flap 11 are unclamped, flap 11 is opened, the locking handle 13 of hinge is positioned at the front position of heading before confirming, flap 11 is opened to spacing position, mobile locking handle 13 inserts latch 12 in the another side locating hole of bearing 1, and locking handle 13 is rotated down the back stop slot 9 of putting into fixed handle 13, unclamps flap 11, flap 11 stops operating owing to action of gravity is pressed on the latch 12, is in the needed stop state of opening.

2. flap closes

Flap 11 is turned to spacing position, locking handle 13 is rotated the back stop slot 9 that leaves locking handle 13, enter in the sliding tray 8 of latch 12.Mobile locking handle 13 is closed flap 11 to the other end of sliding tray 8, connects flap 11 connector all around.
