Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear, the present utility model will be further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

Please refer to Figures 1 to 5 together to describe the quick installation and removal structure of the fan blade provided by the present invention. The fan blade quick installation and disassembly structure includes a hanging plate 1 and a fan blade 2. The hanging plate 1 is provided with at least one radial elastic piece 4 that can be radially expanded. The radial expansion direction of the radial elastic piece 4 is in the same direction as that of the hanging plate 1. The radial direction is consistent; the plug-in part 201 of the fan blade 2 is provided with a socket 203. The plug-in end of the fan blade 2 extends into the hanging plate 1 through the limit hole 101 on the side wall of the hanging plate 1. The socket 203 is inserted in the radial direction. The shrapnel 4 is elastic.

The utility model provides a quick installation and disassembly structure for fan blades. A radial elastic piece 4 is fixed on the hanging plate 1, and a socket 203 adapted to the radial elastic piece 4 is provided at the plug-in part 201 of the fan blade 2. During installation, The plug-in part 201 passes through the limiting hole 101 on the hanging plate 1 in the radial direction, and presses and pushes the radial elastic piece 4 in the radial direction, so that the radial elastic piece 4 bends and elastically deforms until the radial elastic piece 4 is at the socket 203. Without being suppressed, the fan blade 2 can be elastically reset by extending from the socket 203, and the fan blade 2 can be connected to the hanging plate 1; when disassembling, the fan blade 2 is pulled radially outward, and the fan blade 2 exerts a reaction force on the radial elastic piece 4. By pushing forward, the radial elastic piece 4 bends and deforms again until it is pulled out from the socket 203, and the fan blade 2 can be detached from the hanging plate 1.

The quick installation and disassembly structure provided by this embodiment is simple in structure and easy to assemble. During the installation and disassembly process of the fan blade 2, the fan blade 2 does not need to be fastened and installed with the screws 5, nor does it need to be disassembled and installed with the help of tools, only by hand.

An elastic compression gap is formed between the parts 404, and the radially reinforced elastic part 403 is located on the side close to the center of the suspension plate 1. The elastic force of the radial elastic part 404 is relatively weak in the radial direction. In order to prevent the fan blade 2 from protruding from the radial elastic part 404 when the centrifugal force is large, a radially reinforced elastic part 403 is also provided. By strengthening the radial elastic part 403 and the double-layer elasticity of the radial elastic part 404, when the outward centrifugal force of the fan blade 2 needs to overcome the double-layer elasticity, the difficulty increases, thus avoiding the problem of the fan blade 2 coming out, and improving the efficiency of the fan blade 2 after installation. of firmness.

In some embodiments, as shown in FIGS. 4 to 5 , the radially reinforcing elastic part 403 protrudes in the direction of the radial elastic part 404 to form a limiter for the limiter plug part 201 on one side toward the center of the suspension plate 1 slot 405. When the socket 203 of the plug-in part 201 is plugged into the radial elastic part 404 and the radial reinforcing part, the plug-in part 201 is just located at the limiting groove 405, and the limiting groove 405 plays a role in the axial displacement of the plug-in part 201. The limiter function, the limiter groove 405 and the limiter hole 101 on the hanging plate 1, together ensure the axial position of the fan blade 2 after installation and operation, and prevent the fan blade 2 from warping or tilting, which will affect the fan. Normal rotation of leaf 2 works.

In some embodiments, as shown in FIGS. 1 to 5 , the lower end of the radially reinforced elastic part 403 has a support part 402 extending radially toward the center direction of the suspension plate 1 , and the support part 402 is parallel to the radial fixed part 401 . In the same way, when the plug-in part 201 is plugged into the radial elastic piece 4, there will be a certain distance between the front end of the plug-in part 201 and the bottom of the suspension plate 1.

The firmness after installation and the reliability of the fan blade 2 during operation.

When the user wants to replace the fan blade 2 or remove it for cleaning, his or her hand or a hand-held tool presses the chordal elastic piece 3 and presses downward, the chordal elastic piece 3 can elastically deform and expand outward, and the chordal elastic part 302 leaves the fan. The bayonet 202 on the blade 2 can be quickly disassembled by pulling the fan blade 2 outward; when it is necessary to install the fan blade 2, the plug-in part 201 of the fan blade 2 is pushed into the hanging plate 1 and plugged in. The part 201 has a trapezoidal structure, and the inclined surfaces on both sides of it contact the chord-direction elastic part 302 and gradually push the chord-direction elastic part 302 outward, so that the chord-direction elastic part 302 opens until it meets the bayonet 202, and the chord-direction elastic part 302 302 is reset and locked in the bayonet 202. At the same time, the front end of the plug-in part 201 pushes and presses the radial elastic part 404 until the radial elastic part 404 meets the socket 203 and is reset and inserted into the socket 203. Then the fan can be Leaf 2 is installed in place.
