Abstract

The invention discloses a folding propeller with limiting structures and belongs to the technical field of aviation devices. The folding propeller with the limiting structures comprises a propeller clamp and propeller blades, wherein the propeller blades are rotationally connected with two sides of the propeller clamp, propeller blade limiting structures are arranged on the folding propeller, U-shaped openings are formed in tail ends of two sides of the propeller clamp in the horizontal direction, roots of the propeller blades are rotationally arranged in the U-shaped openings through a vertical shaft, and each propeller blade limiting structure is arranged between the propeller clamp and the corresponding propeller blade. In the transportation process, the folding propeller can keep a folding state reliably, various problems caused by swinging of the propeller blades in the transportation process are prevented, the folding propeller can be in an unfolding state reliably during flying through the limiting structure as is required, smooth take-off is guaranteed, and the folding propeller with the limiting structures has a good technical effect.

Description

technical field

[0001] The invention relates to a folding paddle, in particular to a folding paddle with a limiting structure, and belongs to the technical field of aviation devices. Background technique

[0002] Folding propellers are widely used in aircraft due to their convenient storage and transportation, and reliable work after unfolding according to requirements. At present, the traditional installation mechanism of folding propellers mainly includes propeller clips and shafts (the shafts are usually replaced by screws), among which the propeller The clip is installed on the power shaft of the aircraft. The two ends of the propeller clip are U-shaped openings. There are fixed shafts or rotating shafts in the up and down direction at the U-shaped openings of the propeller clips. The fixed shaft or rotating shaft is usually replaced by a long screw. It is used to install the propeller. There is a shaft hole at the root of the propeller. Under the restriction of the prop...
