Abstract
The utility model discloses an inserting mechanism for a propeller machine arm of an aircraft. The inserting mechanism comprises a propeller machine arm consisting of two sections which are detachably connected; a detachable inserting structure is connected between the outer ends of the two sections; the inserting structure comprises a locating pin, an inner connector and an outer connecting sleeve, wherein the inner connector and the outer connecting sleeve are nested with each other; the inner connector is pushed horizontally in the axial direction and sleeved into the outer connecting sleeve so as to limit the circumference rotation of the inner connector; the locating pin vertically penetrates through the inner connector and the outer connecting sleeve so as to limit the axial movement of the inner connector. According to the inserting structure for the propeller machine arm of the aircraft, the propeller machine arm consists of a plurality of sections which are detachably connected.
Description
Technical field
The utility model relates to a kind of aircraft, particularly a kind of connected structure of aircraft propeller horn.
Background technology
Existing many rotor unmanned aircrafts structure is: in the middle of aircraft fuselage is positioned at, be distributed with a plurality of motors and motor cabinet at the aircraft fuselage excircle, screw propeller is housed on the motor, and motor is positioned at motor cabinet, and motor cabinet is structure as a whole by screw propeller horn and aircraft fuselage shell.Existing aircraft propeller horn is a whole pipe link, for a plurality of screw propellers are installed, then need enough large spacing between the screw propeller, therefore, the screw propeller horn tends to the length that is designed to grow, such screw propeller horn processing requires high: because the screw propeller horn is structure as a whole with the aircraft fuselage shell, the screw propeller horn of length is the depositing, transport of inconvenient aircraft also simultaneously.For this reason, the applicant has created the technology of present patent application.
The utility model content
The utility model purpose is in order to overcome the deficiencies in the prior art, to provide a kind of screw propeller horn that multistage is arranged, the connected structure of the aircraft propeller horn that removably connects between each section.
The purpose of this utility model is achieved through the following technical solutions:
The connected structure of aircraft propeller horn, comprise the screw propeller horn, the screw propeller horn forms by two sections that removably connect, be divided into first paragraph and second segment, first paragraph root and aircraft fuselage shell are connected as a single entity, second segment is connected to the first paragraph outer end, the second segment outer end is provided with the aircraft electrical support, between second segment the inner and the first paragraph outer end detouchable connected structure is arranged, this connected structure comprises locating dowel pin, interior connector and the outer adapter sleeve of mutual fit, it is interior to limit interior connector circular-rotation that outer adapter sleeve is inserted in the axial horizontal sliding of interior connector, and locating dowel pin vertically passes interior connector and outer adapter sleeve moves axially to limit interior connector.
Wherein, first paragraph and second segment are hollow tubular, and interior connector is two projections that are positioned at second segment the inner, and the projection upper and lower side is the plane edge that limits its circular-rotation; Outer adapter sleeve is positioned at the first paragraph outer end, is provided with the cavity volume that cooperates with interior connector outer rim in the outer adapter sleeve, and the axial horizontal sliding of interior connector is inserted in the cavity volume, thus connector and the locking of outer adapter sleeve circumferencial direction in realizing.
Improve: two through hole vertically passes interior connector and outer adapter sleeve both sides, and locating dowel pin has two, and two locating dowel pins are tightly placed in the two through hole respectively.
Improve: locating dowel pin stretches out outside the outer adapter sleeve after passing through hole, and locating dowel pin stretches out outer adapter sleeve one end and also has lockhole, and a pin interts and endwisely slips to limit locating dowel pin in lockhole.
The utility model has following advantage and effect with respect to prior art: the aircraft propeller horn forms by two sections that removably connect, the detouchable connected structure is arranged between two sections, connected structure comprises interior connector and the outer adapter sleeve of locating dowel pin, mutual fit, the axial horizontal sliding of interior connector is inserted in the outer adapter sleeve to limit interior connector circular-rotation, locating dowel pin vertically passes interior connector and outer adapter sleeve moves axially to limit interior connector, simple in structure, and the screw propeller horn is split as multistage, makes things convenient for depositing, transporting of aircraft.
