Abstract

The invention discloses a convenient to unfold and fold metal fan blade which comprises a fixed seat, a fan blade hinge joint sleeve embedded in the middle of the fixed seat, a plurality of fan blades, a screw rod in pivot joint with the lower end of the fan blade hinge joint sleeve, a sliding sleeve in threaded connection with the screw rod, a connecting rod and a rotary knob fastened to the lower end of the screw rod, wherein the fan blades are in hinge joint with the peripheral surface of the fan blade hinge joint sleeve in the circumferential direction; two ends of the connecting rod are in hinge joint with the fan blades and the sliding chutes; the rotary knob is in pivot joint with the lower end of the fixed seat; and a sliding chute for unfolding and folding the fan blades is formed in the peripheral surface of the fixed seat. According to the structural design, the screw rod is rotated through the rotary knob to drive the sliding sleeve to move up and down in the length direction of the screw rod, so that the fan blades are folded and unfolded through the function of the connecting rod, and various trouble caused by the fan blade dismantling process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of metal fan blades, in particular to a conveniently retractable metal fan blade device. Background technique [0002] In the prior art, the large metal fan blades used in factories must be stored and stored separately during transportation. When in use, they must be installed together with the driving part of the fan before they can be used normally. Due to the length of the metal fan blades It is relatively long, so when it is installed and disassembled, it will bring a lot of inconvenience, and it is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a metal fan blade device that is convenient to unfold, transport and use. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A convenient metal fan blade device, comprising a fixed seat, a fan blade hinged sleeve buried in the middle o...
