Abstract
Self-locking device is hindered the present invention relates to a kind of increasing for wing flap or slat handle, for improving the man-machine handling during pilot driver.Existing structure realizes manipulation demand using movable friction plate, static friction piece, during wing flap or slat handle use, steering force change greatly, it is unstable, when manipulating to wing flap or slat requirement graduation position, feel is resetted without obvious, and when steering force is unsatisfactory for use requirement, need analytical product to be debugged, adjustable is poor.The present invention is designed by reasonable compact structure layout and configuration, realized using the structure of steel ball plus cylindroid helical-coil compression spring and manipulate and reset feel, guide groove is provided with version is installed simultaneously, bearing is raised (or downward) along guide groove direction, to correct position, make the hexahedron boss clamping stagnation of bearing in six side's grooves of locking nut, steering force adjustment and structure self-locking can be realized.
Description
Technical field
Self-locking device is hindered the present invention relates to a kind of increasing for wing flap or slat handle, for improving in pilot driver mistake
Man-machine handling in journey.
Background technology
Increasing resistance self-locking device in wing flap or slat handle is mainly used in realizing the manipulation of driver, resets feel.It is existing
Structure realizes manipulation demand using movable friction plate, static friction piece, during wing flap or slat handle use, steering force change
Greatly, it is unstable, when manipulating to wing flap or slat requirement graduation position, feel is resetted without obvious, and when steering force is unsatisfactory for making
During with requiring, analytical product is needed to be debugged, adjustable is poor.
The content of the invention
Present invention seek to address that pilot control power is unstable in wing flap or slat control crank, manipulate to correspondence scale position
Feel is resetted when putting unobvious, and steering force is not easy to the technical problems such as adjustment.
The present invention's is used for the increasing resistance self-locking device of wing flap or slat handle, including locking nut, bearing, cylindrical screw pressure
Contracting spring, gag lever post, steel ball, steel ball seat and shell；The shell is circular cylindrical structure, there is circular boss inside it,
The steel ball, steel ball seat, cylindroid helical-coil compression spring, bearing and locking nut are sequentially installed with the downside of the boss, it is convex at this
The gag lever post that can be operated in a plane is installed on the upside of platform；Its operation direction of the lower end edge of the gag lever post is with one
The stopper slot of row rounding off.
The locking nut is connected by screw thread with the lower openings of the shell, has six faces recessed in the locking nut
Groove.
The lower end of the bearing is hexahedron boss, can be connected with six face groove, have cylindrical projection in its upper end.
The present invention is designed by reasonable compact structure layout and configuration, using steel ball plus the knot of cylindroid helical-coil compression spring
Structure, which is realized, manipulates and resets feel, while being provided with guide groove on version is installed, bearing raises (or downward) along guide groove direction, extremely
After correct position, make the hexahedron boss clamping stagnation of bearing in six side's grooves of locking nut, can realize steering force adjustment and
Structure self-locking.
Beneficial effect：The present invention solves wing flap or the steering force of slat handle changes big, unstable in use,
Reset feel unobvious, and steering force is not easy to the technical problems such as adjustment.The present invention adds cylindroid helical-coil compression spring using steel ball
Structure realizes the Control requirements of wing flap or slat handle, during product use, and steering force is stable, manipulates to correspondence scale position
When putting, feel is resetted substantially, without the special attention of driver, and steering force debugging is easy to be steerable, without being carried out to product
Exploded, you can realize debugging, manpower, financial resources and material resources are saved relative to standing state.

Shell
Embodiment
As shown in figure 1, for wing flap or slat handle increasing hinder self-locking device, the device include locking nut 1, bearing 2,
Cylindroid helical-coil compression spring 3, gag lever post 4, steel ball 5, steel ball seat 6 and shell 7；The shell 7 is circular cylindrical structure, in it
There is circular boss in portion, and the steel ball 5, steel ball seat 6, cylindroid helical-coil compression spring 3, bearing are sequentially installed with the downside of the boss
2 and locking nut 1, the gag lever post 4 that can be operated in a plane is installed on the upside of the boss；Under the gag lever post 4
Hold a series of stopper slot for operating direction that there are rounding ofves along it.
The locking nut 1 is connected by screw thread with the lower openings of the shell 7, has six faces in the locking nut 1
Groove.
The lower end of the bearing 2 is hexahedron boss, can be connected with six face groove, have cylindrical projection in its upper end.
During product normal work, pilot control gag lever post motion, gag lever post acts on steel ball, makes steel ball from current scale
Ball-and-socket, which is moved to, requires graduation position ball-and-socket.In manipulation process, driver is firstly the need of overcoming cylindroid helical-coil compression spring
Spring resistance, makes steel ball depart from current location ball-and-socket, and then push/pull manipulates gag lever post, manipulates to when requiring graduation position, is pressed
Contracting spring discharges Partial shrinkage power and acts on steel ball, and driving steel ball is moved in corresponding ball-and-socket, so as to be provided to driver
Certain reset feel.
When wing flap or slat stick control power are unsatisfactory for product use requirement, along the guide groove direction on shell by bearing
Prop, locking nut is raised to (when steering force is less than normal) in the axial direction with adjustment spanner or lowered (when steering force is bigger than normal), is adjusted
It is whole to unclamp bearing to after correct position, while the hexahedron boss clamping stagnation for making bearing is realized in six side's grooves of locking nut
Steering force is adjusted and structure self-locking.
