All adopt the aircraft door mechanism of soft pulley, cable control mechanism also not find at present both at home and abroad, but will occur, if but adopt above-mentioned handle mechanism to be connected with the soft steering unit of hatch door; This handle mechanism can well address this problem, and a pulley is installed in the middle of the handle, and cable wire is walked around pulley and is fixed on handle one end; When pulling the handle rotation; Cable wire drives pulley rotating, is fixed by connecting element after handle turns an angle, and handle is spacing.

This mechanism design principle is ingenious; Satisfy the requirement of aircraft door handle design; Can regulating handle power big or small through regulating pulley size and the long relation of handle bar; Be applicable to the aircraft door handle mechanism design use of adopting the soft operation of wire rope pulley, the hatch door handle mechanism design that can be used for rigid connecting rod operation is equally used.

The utility model content

The purpose of the utility model: design the cooresponding handle mechanism of hatch door a kind of and the soft manipulation of employing pulley cable wire; Intensity and toughness satisfies the relevant design requirement; And handle mechanism is wanted ability regulating handle power size, and taking cabin space can not be too big; Reliable spacing measure will be arranged after simultaneously, handle is opened.

The technical scheme of the utility model is:

A kind of type aircraft hatch door handle mechanism is characterized in that, comprises handle box, handle, locating part, pulley, cable wire, cable wire ball-and-socket type joint, extension spring, extension spring seat; The handle box is fixed on the airframe structure, and handle and pulley are coaxial to be installed on the handle box, has the pulley mounting groove in the middle of the handle; Place pulley in the pulley mounting groove, handle, pulley can rotate around installation shaft, and tiller grip has cable wire to pass through the hole; Cable wire walks around pulley and the cable wire ball-and-socket type joint is fixed on tiller grip, has cylindrical guide on the handle, and cylindrical guide moved in the deep-slotted chip breaker on the handle box when handle rotated; Locating part is installed on the handle box; Can rotate around installation shaft, locating part one end is connected with extension spring one end, and the extension spring other end is connected with extension spring seat on being fixed on the handle box.

The utility model beneficial effect is: designed the handle mechanism that a kind of soft hatch door steering unit is used, principle is novel, arranges compact ingenious; The utility model is suitable for equally and is connected with rigid hatch door kinematic mechanism, and commonality is good; The said handle mechanism handle of the utility model power is adjustable, handle has spacing measure, satisfies handle and uses relevant designing requirement, has expanded the thinking and the method for new handle design.

Wherein, 1-handle box, 2-handle, 3-locating part, 4-pulley; The 5-cable wire, 6-cable wire ball-and-socket type joint, 7-extension spring, 8-extension spring seat, 9-handle, pulley mounting hole; 10-locating part mounting hole, the 11-deep-slotted chip breaker, 12. pulley mounting grooves, 13-handle mounting hole, 14. cable wires pass through the hole; The cylindrical guide of 15-, 16-locating part mounting hole, 17-tension spring hook seat, 18-extension spring dog hole.

The specific embodiment

Through the specific embodiment the utility model is further described below:

This aircraft door handle mechanism is made up of handle box 1, handle 2, locating part 3, pulley 4, cable wire 5, cable wire ball-and-socket type joint 6, extension spring 7, extension spring seat 8.

Have a deep-slotted chip breaker 11 and handle, pulley mounting hole 9 and locating part 3 mounting holes on the sidewall of handle box 1, be fixedly mounted on the airframe structure.The mounting groove 12 that handle 2 front ends have a pulley 4 and handle mounting hole 13 and a cable wire that is used for passing cable wire 5 are through hole 14; Front end one side has cylindrical guide 15; Handle 2 passes through handle, pulley mounting hole 9 and the 1 coaxial installation of handle box on the handle 2 with pulley 4; This moment, the cylindrical guide 15 on it was in deep-slotted chip breaker 11 tops of handle box 1, and pulley 4 is in 12 li of the pulley mounting grooves of handle 2.Cable wire 5 is walked around pulley 4 and is fixed on cable wire ball-and-socket type joint 6 on the termination of handle 2 through the hole with the cable wire that passes on the handle 2, and the other end can be connected with the aircraft door kinematic mechanism through cable connector.Locating part 3 is a hook shape, and front end has a locating part mounting hole 16, and there is protruding tension spring hook seat 17 with holes the rear end, through the mounting hole 16 of front end and the locating part mounting hole 10 coaxial installations on the handle box 1.Extension spring 7 one ends are connected with hole on the locating part 3 rear end tension spring hook seats 17, and the other end is connected with the extension spring dog hole 18 of extension spring seat 8 on being fixed on handle box 1.

When pulling handle 2; Cylindrical guide on the handle 2 moves towards the other end from deep-slotted chip breaker 11 tops on the handle box 1; After rotating about 87 °, contact, rotate, when locating part 3 hook upper surfaces entering hook bottom is walked around in cylindrical guide 15 rotations of handle 2 thereby promote locating part 3 with locating part 3 hook upper surfaces; Because extension spring 7 applies the opposing torque effect, handle 2 is locked.

After handle 2 is locked, pushes locating part 3 towards extension spring 7 prolonging directions cylindrical guide and locating part 3 hooks on the handle 2 are broken away from, pull handle 2 and can return to the home position, at this moment, locating part 3 is withdrawn into original position under the effect of extension spring 7.

During concrete the application, can change lever operated power through the arm of force length of regulating handle 2 and the diameter of pulley 4, the angle that handle 2 rotates can be regulated through the deep-slotted chip breaker length that changes on the handle box 1.
