Abstract

The invention provides an airplane radome in-and-out hatch door, which comprises a hatch door structure (1), a transmission structure (2), an assistance structure (3), a locking structure (4), and a hatch door installation structure (5). The hatch door structure (1) comprises a box like member (11) and multiple ribs (12) arranged in the box like member (11). In the box like member (11), a transmission shaft (21) is fixed on the ribs (12) through a support (25); inner / outer handles sleeve the middle part of the rotation shaft (21), rocking arms (22) sleeve two ends of the rotation shaft (21); the rocking arms are connected to a cam lock (41) that penetrates the outer frame of the box like member (11) through a connection rod (42); the hatch door installation structure (5) for connecting thehatch door structure (1) and a radome opening frame is installed on the ribs (12); the external surface of the box like member (11) is provided with a stop joint (43); and a stop screw (44) for adjustment is arranged on the stop joint (43). The structure is simple, the force transmission performance is good, and the opening and closing of two sides of a hatch door can be realized.

Description

technical field [0001] The invention belongs to the field of aviation technology, in particular to the field of aircraft radome, in particular to an aircraft radome entry and exit cabin door. Background technique [0002] In order to enter and exit the radome for equipment installation or maintenance, it is necessary to open the entry and exit hatch on the lower wall of the large radome. How to arrange the hatch locks to ensure smooth opening, safe locking, easy sealing, and effective load transmission are design difficulties. Especially for a rotating radome, if the access door opens outwards, accidental rotation will easily damage the bracket connected to the radome. In addition, if you open the hatch at high altitude, if you use a screwdriver to screw the multi-lock to open and close the hatch, it will be unsafe and inconvenient. Contents of the invention [0003] The object of the present invention is to provide an aircraft radome access door, which overcomes or allev...
