Cabin section connecting structure and aircraft

Abstract

The invention is applicable to the field of aircrafts, and provides a cabin section connecting structure and an aircraft. The cabin section connecting structure comprises: a first cabin section provided with a butt joint bolt, a second cabin section, a worm-wheel shaft, a first threaded sleeve, a second threaded sleeve, an explosive bolt, an abutting nut, and a worm. A mounting cavity is formed inone end of the second cabin section, and a mounting hole is formed in the side surface of the second cabin section; the worm-wheel shaft is rotationally arranged in the mounting cavity; the first threaded sleeve is in transmission connection with the worm-wheel shaft; the second thread sleeve is used for limiting the first thread sleeve in the second cabin section; the explosive bolt is connectedwith the second threaded sleeve, and the explosive bolt is fixed to the second cabin section through the second threaded sleeve; the first threaded sleeve is in transmission connection with the worm-wheel shaft; the abutting nut is fixedly connected with the first threaded sleeve; and the worm is mounted in the mounting hole and is in transmission connection with the worm-wheel shaft. According to the cabin section connecting structure, the worm is used for driving the worm wheel shaft to rotate, butt joint or separation of the second cabin section and the first cabin section is achieved; theoperation space needed for rotating the worm is located outside the second cabin section, an operation opening does not need to be additionally formed in the second cabin section, and good structuralstrength of the cabin section is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a cabin connection structure and an aircraft. Background technique [0002] During the flight of the multi-stage aircraft, some of the excess weight that has completed the flight mission needs to be thrown away in advance. The two revolving cabin sections that need to be separated from each other on the aircraft are generally connected and fixed by several explosive bolts distributed in the circumferential direction before separation. [0003] In the prior art, since the cabins of the aircraft that need to be separated from each other are directly connected and fixed by explosive bolts, when the two cabins are docked on the ground, it is necessary to put the explosive bolts into the cabin through the operating port opened in the cabin and pass them through. through the butt bolt hole, and use a special external hexagonal wrench to tighten through the operation port. After the e...
