Abstract
The utility model discloses a novel undercarriage control handle, comprising a shell (1), a control handle (2), a microswitch (3), an electromagnet (4) and a mechanical locking mechanism (5). The handle is characterized in that the microswitch (3), the electromagnet (4) and the mechanical locking mechanism (5) are installed in the shell (1); the control handle (2) is connected with the microswitch (3) and the mechanical locking mechanism (5) and protrudes out of the shell (1); when the air-ground state of the aircraft is air, the electromagnet is energized to open the mechanical locking mechanism connected with the electromagnet and the control handle can be pulled from the position of putting down to the position of retracting; and when the air-ground state of the aircraft is ground, the electromagnet is deenergized and the mechanical locking mechanism locks the control handle so that the control handle can not be pulled from the position of putting down to the position of retracting. The handle has simple and practical principle, is reliably protected, reduces the risk of misoperation by using the electromagnet to cut off the signal source, reduces the possibility of mis-retracting of undercarriage ground and improves the safety of the aircraft.
Description
Technical field
The utility model belongs to undercarriage control field, is a kind of anti-handle of packing up in undercarriage ground that is used for.
Background technology
The gear up circuit of existing aircraft is controlled by the interlocking relay that simply contacts to earth, when wheel contacts to earth, this relay is with the gear up circuitry cuts, undercarriage can not be packed up on ground, and landing-gear control is not limited by the vacant lot state, aircraft is when ground, and handle can be pulled from " putting down " position to " packing up " position, and the anti-receipts measure in this kind undercarriage ground has two shortcomings:
The first, can not prevent that landing-gear control mistake from packing up operation, promptly do not take anti-receipts measure from the source of signal;
The second, adopt simple relay to realize the gear up connecting and disconnecting of the circuit, prevent that the undercarriage mistake is packed up behind ground contact.This kind measure is subjected to the influence that electromagnetic environment, voltge surge and relay lost efficacy easily, thereby causes anti-receipts measure to be lost efficacy.
Summary of the invention
The purpose of this utility model is: reduce the risk of landing-gear control misoperation, reduce the possibility that undercarriage ground mistake is packed up, the fail safe that improves aircraft.
The technical solution of the utility model is: a kind of novel landing-gear control, comprise housing 1, control crank 2, sensitive switch 3, electromagnet 4, mechanical lock mechanism 5, it is characterized in that sensitive switch 3, electromagnet 4, mechanical lock mechanism 5 are installed on housing 1 inside; Control crank 2 links with sensitive switch 3, mechanical lock mechanism 5 and gives prominence in housing 1 outside; When aircraft vacant lot state was " sky ", mechanical lock mechanism joining with it opened in the electromagnet energising, and control crank can be pulled from " putting down " position to " packing up " position; When the vacant lot state be " " time, electromagnet outage, mechanical lock mechanism locking control crank makes control crank not pull to " packing up " position from " putting down " position.
Advantage and the beneficial effect that the utlity model has are: the principle of the invention is simple and practical, and protection is reliable, by electromagnet shutoff signal source, has reduced the risk of misoperation, has reduced the possibility that undercarriage ground mistake is packed up, the fail safe that has improved aircraft.

Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1, a kind of novel landing-gear control comprises housing 1, control crank 2, sensitive switch 3, electromagnet 4, mechanical lock mechanism 5, it is characterized in that, sensitive switch 3, electromagnet 4, mechanical lock mechanism 5 are installed on housing 1 inside; Control crank 2 links with sensitive switch 3, mechanical lock mechanism 5 and gives prominence in housing 1 outside; When aircraft vacant lot state was " sky ", mechanical lock mechanism joining with it opened in the electromagnet energising, and control crank can be pulled from " putting down " position to " packing up " position; When the vacant lot state be " " time, electromagnet outage, mechanical lock mechanism locking control crank makes control crank not pull to " packing up " position from " putting down " position.
