Abstract
The invention discloses a cabin door mounting seat. According to the cabin door sensor mounting seat, one end of a sliding sleeve provided with a sliding surface is positioned in a supporting sleeve; one end of a target seat provided with a sliding surface is arranged in the sliding sleeve and is in sliding fit with the inner surface of the sliding sleeve; an inner spring is arranged in an inner hole of the sliding sleeve and is matched with an end face of the sliding surface end of the target seat; a fine adjustment bolt is arranged at the other end of the inner hole of the sliding sleeve; an outer spring is sleeved on the outer surface of one end of the sliding sleeve; and an induction surface of the target seat is positioned at one end of the target seat and is matched with the end face of the target seat. During use, a sensor is arranged on a mounting box, and the requirement of the effective working distance of the sensor is met through the fine adjustment bolt; when a cabin door handle is rotated anticlockwise, a rocker is driven to rotate to a horizontal position, a door fork presses down a tongue piece, and the distance between the induction surface of the sensor and the target is always in an inductive range under the action of the inner spring; and when the cabin door handle is rotated clockwise, the target is separated from a working area under the action of the outer spring, and the sensor warns opening of the cabin door. According to the tests, when the cabin door is opened and closed every 100 times averagely, the error indication phenomenon time of a warning lamp is zero.
Description
Technical field
The present invention relates to aeroplane structure design field, specifically a kind of hatch door sensor installation seat.
Background technology
The afterbody hatch door of certain type machine is the entrance door of fuselage deck store, and its Main Function is that the maintenance for deck store structure and control system provides passage.Aircraft is in flight course, and this door and other hatch door common guarantee fuselage interior are airtight, on its frame door, are provided with door lock and alarm switch, and when hatch door is during in correct off-position, alarm switch extinguishes the stand by lamp of driving cabin; When hatch door is in an open position, alarm switch makes stand by lamp bright aobvious, and whole process realizes by the mechanical motion between door lock and alarm switch.
Original structure is that door fork directly contacts with alarm switch.Owing to manufacturing assembly precision, the reason such as in flight course the working range of the distortion of housing construction under inside and outside differential pressure effect and switch itself is less, if adopt original structure may occur the phenomenon that stand by lamp mistake is indicated.
Summary of the invention
For overcoming the deficiency that there will be the indication of stand by lamp mistake existing in prior art, the present invention proposes a kind of hatch door sensor installation seat.
