Technical Field

The invention relates to the technical field of aircrafts, in particular to a three-switch linkage pressing mechanism capable of self-resetting.

Background

When the aircraft takes off, a take-off button head needs to be pressed to provide a take-off state electric signal (state retention) for a flap system; when the aircraft enters a cruising state, operating the retraction button head, quickly disconnecting the electric signal in the take-off state and providing the electric signal in the retraction state for the flap system (state keeping); when an aircraft lands, a landing button head is operated, a retracting state electric signal is quickly disconnected, and a landing state electric signal (state keeping) is provided for a flap system. The structure is complex, the micro switch is unreliable in work, the structural layout is not compact enough, the assembly and disassembly are difficult, the coaxiality of the rocking plate is poor, and the reliability is low when the button head is reset and pressed.

Disclosure of Invention

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention discloses a three-switch linkage pressing mechanism capable of self-resetting, which is characterized in that a pressing mechanism is arranged on a base; a microswitch is installed at the lower end of a support, an angle piece is installed on the side face of the microswitch, a sleeve is inserted into the upper end of the support and is screwed into a nut for connection, a reset button is fixedly connected with the upper end of a connecting rod, a spring B is sleeved on the lower end of the connecting rod and is inserted into the sleeve, a gasket is sleeved on the upper end of a rack and is screwed into a button head, a spring A is sleeved on the middle of the rack and is inserted into the support, the lower end of the rack is inserted into the angle piece on the side face of the microswitch, a short spring plunger is installed in the middle of the rack, a rocker plate is placed behind the support, two ends of the rocker plate are screwed into screws respectively for hinging, and two ends of the spring B are hung on a cotter pin and the rocker plate respectively.

The middle part of the rack is provided with wavy teeth, and the side surface of the rack is provided with right-angle steps.

The front end of the rocking plate is respectively provided with a hook and a boss.

The hook-shaped gear arranged at the front end of the rocking plate is clamped into the wavy gear arranged on the rack.

The link is movable up and down.

The rack is movable up and down.

The rocking plate can rotate on the bracket by taking the screw as a center.

Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: a microswitch is installed at the lower end of a support, an angle piece is installed on the side face of the microswitch, a sleeve is inserted into the upper end of the support and is screwed into a nut for connection, a reset button is fixedly connected to the upper end of a connecting rod, a spring B is sleeved on the lower end of the connecting rod and is inserted into the sleeve, a gasket is sleeved on the upper end of a rack and is screwed into a button head, a spring A is sleeved on the middle of the rack and is inserted into the support, the lower end of the rack is inserted into the angle piece on the side face of the microswitch, a short spring plunger is installed in the middle of the rack, a rocker plate is placed behind the support, the two ends of the rocker plate are screwed into screws respectively for hinging, and the two ends of the spring B are hung on a cotter pin and the rocker plate respectively. The button head is pressed, a spring A at the lower end of the button head is compressed, the button head pushes a rack, the rack drives a short spring plunger to move downwards, the short spring plunger presses a microswitch, a hook-shaped part arranged at the front end of a rocking plate is clamped into a wavy tooth arranged on the rack and locked at a pressing position, and a response electric signal is output; when the reset button is pressed, a spring B below the reset button is compressed, the reset button drives a connecting rod to move downwards, the connecting rod pushes a boss arranged at the front end of a rocking plate, the rocking plate rotates on a support by taking a screw as a center, a hook-shaped part arranged at the front end of the rocking plate is separated from a wavy tooth arranged on a rack, the rack moves upwards, a short spring plunger is separated from a microswitch, and a button head is reset; the microswitch stops outputting the electric signal. The locking of the button head is realized by a wavy toothed groove on the rack and a hook-shaped groove arranged at the front end of the rocking plate. Because the short spring plunger has certain flexible volume, through the short spring plunger position on the regulation rack, can ensure that the switch during operation is in the overtravel scope, can guarantee the reliable output of corresponding signal of telecommunication. The device has the advantages of small volume, compact structure, convenient assembly and disassembly and high reliability.
