CN203111514U - Ejection seat ejection signal collection device - Google Patents

Abstract

The utility model provides an ejection seat ejection signal collection device, relates to the aviation protective rescue field and aims at solving the problem that an existing ejection seat of a plane can not collect ejection starting signals. According to the technical scheme, the ejection seat ejection signal collection device comprises an adjustable screw, a microswitch, an installation support, a plug assembly, and a spring sheet, the adjustable screw is a screw which can be adjusted, is fixed with the end of the spring sheet, and abuts against a pin shaft in an ejection operation handle supporting seat after penetrating through a through hole in a seat beam and a through hole in the ejection operation handle supporting seat, the microswitch is fixed on the seat beam through the installation support and is located under the spring sheet, clearance exists between a contactor of the microswitch and the bottom of the spring sheet, and the microswitch is connected with the plug assembly. The ejection seat ejection signal collection device can collect ejection starting signals in the working process of the ejection seat, can know whether a pilot starts ejection on emergency conditions, and is suitable for various ejection seats.

Description

Ejection-seat ejection signal harvester

Technical field

The utility model relates to airway protection lifesaving field, relates in particular to a kind of ejection-seat ejection signal harvester.

Background technology

Ejection-seat plays indispensable effect as the visual plant of fleeing from aircraft for saving aviator's life under the aircraft emergency condition.In the aviation accident, because ammunition and the priming system of ejection-seat equipment are more, cartridge may weigh down under the effect of hitting ground at body works, and in this case, is difficult to the service condition of ejection-seat is accurately judged, accident analysis is caused puzzlement.

The utility model content

The purpose of this utility model is: a kind of ejection-seat ejection signal harvester is provided, ejection-seat ejection signal and ejection escape signal are gathered, be beneficial to the ejection-seat service condition is judged and the aircraft accident analysis.

The technical solution of the utility model is: a kind of ejection-seat ejection signal harvester comprises:

Expansion screw, micro-switch, mounting bracket, plug-assembly, spring leaf;

Expansion screw is an adjustable screw, fixes with the termination of spring leaf, props up the bearing pin that launches in the bar handle bearing after passing the seat crossbeam and launching through hole on the bar handle bearing; Micro-switch is fixed on the seat crossbeam by mounting bracket, is positioned at the spring leaf below, and the gap is left in its contact and spring leaf bottom, and micro-switch is connected with plug-assembly.

The beneficial effects of the utility model are: the utility model can be gathered in the ejection-seat working process and launch actuation signal, this signal can be inputed to aboard and fly the ginseng system and carry out record, can learn whether the aviator starts under the emergency condition and launch, the ejection-seat service condition is judged and the aircraft accident analysis provides strong evidence.

Description of drawings

The existing bar handle scheme of installation that launches of Fig. 1.

Fig. 2 the utility model launches actuation signal harvester scheme of installation.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

Launch the actuation signal harvester and be installed in and launch near the bar handle 1, gather signal by triggering micro-switch.Formed by expansion screw 4, micro-switch 5, mounting bracket 6, plug-assembly 7, spring leaf 8.Scheme of installation is seen Fig. 2.

Expansion screw 4 is an adjustable screw, fixes with the termination of spring leaf 8, props up the bearing pin 2 that launches in the bar handle bearing 11 after passing seat crossbeam 10 and launching through hole on the bar handle bearing 11; Micro-switch 5 is fixed on the seat crossbeam 10 by mounting bracket 6, is positioned at spring leaf 8 belows, and certain interval is left in its contact and spring leaf 8 bottoms, and micro-switch 5 is connected with plug-assembly 7.Spring leaf 8 one ends are fixed on the ejection-seat crossbeam 10 by screw assembly 9, and the other end is connected with expansion screw 4 by nut assembly 3, sees Fig. 1, Fig. 2.Its principle of work is as follows:

Flying the ginseng system on plug-assembly 7 and the machine is connected, after bar handle 1 is launched in pulling, the lock pin 2 that launches in the bar handle bearing 11 can be done cross motion to the inside, and promotion expansion screw 4 moves downward, thereby press down triggering micro-switch 5 by spring leaf 8, formation power on/off signal is exported from plug-assembly 7, is recorded in to fly in the ginseng system.

Claims (1)

1. an ejection-seat ejection signal harvester is characterized in that, comprising:

Expansion screw, micro-switch, mounting bracket, plug-assembly, spring leaf;

Expansion screw is an adjustable screw, fixes with the termination of spring leaf, props up the bearing pin that launches in the bar handle bearing after passing the seat crossbeam and launching through hole on the bar handle bearing; Micro-switch is fixed on the seat crossbeam by mounting bracket, is positioned at the spring leaf below, and the gap is left in its contact and spring leaf bottom, and micro-switch is connected with plug-assembly.
