Abstract
The invention provides a four-station control switch capable of being simply operated by one hand. The four-station control switch solves the problem that a four-station control switch is operated by two hands. The four-station control switch comprises a handle, a pressure spring, a pull rod, a groove-shaped sliding track, a limiting component, four contacts used for four-station control, wherein an arc-shaped through groove covering four contact stations is formed on the inner side of the groove-shaped sliding track; four sunk notches corresponding to the four contact stations are formed in the arc-shaped through groove; the handle is axially connected with the pull rod through the pressure spring; a guide bump is fixedly and radially arranged on a side wall of the pull rod; and the guide bump is limited to move in the arc-shaped through groove and matched with the four sunk notches in size. With the adoption of the control switch, folding and releasing of a security instruction plane wing flap are realized by simple one hand operation.
Description
Technical field
The present invention relates to four control switchs in a kind of aircraft flap control system.
Background technology
Four control switchs in aircraft flap control system, for instruction aircraft flap 0 °, the folding and unfolding work of 10 °, 20 °, 30 °.Control overflow: during positive operation, allows directly to pull by 0 ° or 10 ° or 20 ° or 30 °, but when oppositely pulling must or 20 ° or 10 ° have stop pause, after having an additional move, just can enter subsequent work position.
Four control switch many employings external position-limiteds of general middle-size and small-size aircraft, must pull open spacing by other hand when oppositely pulling, and need work during operation with two hands simultaneously.Its course of work is loaded down with trivial details.Therefore, need a kind ofly four control switchs of singlehanded simple operations to solve this problem.
Summary of the invention
The invention provides a kind of can four control switchs of singlehanded simple operations, solve the problem with two manual manipulations, four control switchs.
The invention provides following solution:
A kind of can four control switchs of singlehanded simple operations, comprise handle, stage clip, pull bar, grooved slide rail, limit assembly, for four control four contacts, the inner side of grooved slide rail is the arc-shaped slot of covering four contact stations, corresponds to four contact stations and be formed with four sagging notches respectively in arc-shaped slot; Described handle by stage clip with pull rod shaft to being connected, be fixedly installed guiding projection in the sidewall radial direction of pull bar, described guiding projection is limited in arc-shaped slot and moves, and mates with described four sagging notch sizes; If operation forward is the direction of guiding projection movement from left to right in arc-shaped slot, then the right flank being positioned at two middle notches in four notches is provided with chamfering; Described limit assembly has two groups, is fixedly installed in the top of two notches with chamfering respectively; Often organize limit assembly to form by return spring and locating part, wherein the right flank of locating part bottom stops guiding projection mobile generation left in arc-shaped slot, the left surface of locating part bottom is provided with chamfering, smoothly to opening locating part when return spring can make guiding projection move right; The upper end of described stage clip is fixedly installed compressing tablet, and when guiding projection sinks into described notch, this compressing tablet can contact by stage clip reset response and corresponding contact are stable.
During operation four control switchs, as at 0 ° or 10 ° or 20 °, when needs forward is pulled, first mention handle from original position, just can directly pull required service position after disengaging, midway can pass over or 10 ° or 20 °.
When oppositely pulling, directly can not pull 0 ° from 20 ° or 30 °, to stop at 10 ° or 20 ° of limited location structure barrier, only have one to unclamp 10 ° or 20 ° and recur to the additional move of handle, just can enter 0 ° of station.
These four control switchs can singlehanded simple operations, the folding and unfolding of safety command aircraft flap.
Accompanying drawing explanation
Fig. 1 is four control switch structural representations of the present invention.
Wherein, 11-contact; 12-handle; 13-compressing tablet; 14-stage clip; 15-pull bar; 16-slide rail, A is limit assembly and associated mounting location.
Fig. 2 is the enlarged drawing in A portion in Fig. 1, i.e. the scheme of installation of limit assembly.
Wherein, 21-locating part; 22-return spring; 23-guide (guiding projection).
Embodiment
Below in conjunction with principle schematic, four control switchs are described in detail:
During positive operation, mention handle 12, by the orbiting motion that the guide 23 be fixed on pull bar 15 retrains along slide rail 16, the location of instruction release handle needed, pull bar 15 and guide 23 fall in the corresponding notch of slide rail 16 in the effect of stage clip 14, compressing tablet 13 make contact 11, provides the control command of wing flap service position.During positive operation, guide 23 slip from left to right, can make it lift to the locating part 21 opening limit assembly and upper pressure return spring 22, after guide 23 slips over, and locating part 21 return under the effect of return spring 22.
During reverse operating, equally, handle 12 is mentioned; by the orbiting motion that the guide 23 be fixed on pull bar 15 retrains along slide rail 16; when guide 23 slides into limit assembly along C track, due to the barrier effect of locating part 21 pairs of guides 23, handle 12 can not continue to pull.Only have and unclamped by handle 12, guide 23 glides along B track and falls in notch under the effect of stage clip 14, now mentions handle 12 again, and guide 23 just can make the locating part 21 of limit assembly lift, thus completes the reverse operating of additional move.
Claims (1)
1. four control switchs of an one-hand operation, it is characterized in that: comprise handle, stage clip, pull bar, grooved slide rail, limit assembly, for four control four contacts, the inner side of grooved slide rail is the arc-shaped slot of covering four contact stations, corresponds to four contact stations and be formed with four sagging notches respectively in arc-shaped slot; Described handle by stage clip with pull rod shaft to being connected, be fixedly installed guiding projection in the sidewall radial direction of pull bar, described guiding projection is limited in arc-shaped slot and moves, and mates with described four sagging notch sizes; If operation forward is the direction of guiding projection movement from left to right in arc-shaped slot, then the right flank being positioned at two middle notches in four notches is provided with chamfering; Described limit assembly has two groups, is fixedly installed in the top of two notches with chamfering respectively; Often organize limit assembly to form by return spring and locating part, wherein the right flank of locating part bottom stops guiding projection mobile generation left in arc-shaped slot, the left surface of locating part bottom is provided with chamfering, smoothly to opening locating part when return spring can make guiding projection move right; The upper end of described stage clip is fixedly installed compressing tablet, and when guiding projection sinks into described notch, this compressing tablet can contact by stage clip reset response and corresponding contact are stable.
