Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 3, the present embodiment provides a fan blade mounting device for a centrifugal fan, including a bottom plate 1 and a telescopic supporting rod 4; a fixed seat 2 is fixedly connected to the bottom plate 1, a sliding seat 3 is slidably connected to the bottom plate 1, and the sliding seat 3 is arranged opposite to the fixed seat 2; the side surface of the sliding seat 3 is provided with a positioning placing hole 31; a first sliding hole 21 is formed in one side, close to the sliding seat 3, of the fixed seat 2, a second sliding hole 22 is formed in the fixed seat 2, and the first sliding hole 21 is communicated with the second sliding hole 22; the telescopic support rod 4 comprises a limiting part 41 and a supporting part 42; the limiting part 41 can be connected in the second sliding hole 22 in a sliding manner, and the supporting part 42 can be connected in the first sliding hole 21 in a sliding manner; a return spring 5 is arranged in the second sliding hole 22, and the return spring 5 is positioned between the bottom of the second sliding hole 22 and the limiting part 41; the telescopic supporting rod 4 and the positioning placing hole 31 are coaxially arranged.
The positioning placing hole 31, the supporting part 42 and the first sliding hole 21 are all the same in cross section, and the positioning placing hole 31 and the first sliding hole 21 are correspondingly arranged in shape and position; the limiting part 41 and the second sliding hole 22 have the same cross section and are both non-circular cross sections, so that the telescopic support rod 4 is prevented from rotating, and the position of the rotating shaft hole relative positioning placing hole 31 of the fan blade is influenced.
The support portion 42 is a combination of a circular shaft and a linear block, and the linear block is located on the side of the circular shaft.
One side of the sliding seat 3, which is positioned on the fixed seat 2, is connected with an electric cylinder 6, a supporting seat 7 is connected on the electric cylinder 6, and the supporting seat 7 is positioned below the positioning placing hole 31; an arc-shaped groove 71 is arranged on the supporting seat 7.
