[0041] It should also be noted that, in the embodiments of the present application, the same figure mark represents the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0042] The embodiment of the present invention provides a fan blade placement tool, such as Figure 1-Figure 3 and Figure 5 As shown, the fan blade placement tooling includes a base 100, a vertical rod 200 and a limiter 300. The vertical rod 200 is vertically fixed on the base 100. The outer diameter of the vertical rod 200 is smaller than the through hole in the middle of the fan blade 10 for connecting the motor shaft. The fan blade 10 can be strung on the vertical rod 200 through the through hole in the middle. The vertical rod 200 is formed by a plurality of rod sections 210 that are detachably connected. The opposite ends of the rod section 210 are respectively provided with a plug-in portion 211 and a connecting portion 212, wherein the plug-in portion 211 of one rod section 210 can be detachably connected to the connecting portion 212 of another rod section 210. The limiter 300 includes a clamping member 310 and a limiter rod 320 connected to the clamping member 310. The clamping member 310 can be clamped on the rod section 210 from the side of the rod section 210. The limiter rod 320 is used to support and limit the fan blade 10 located above the clamping member 310.

[0043] The fan blade placement tooling has a simple structure and low cost; Figure 5 As shown, the tested blades 10 can be strung on the pole 200 from top to bottom, saving floor space and making it easy to find; since the pole 200 is formed by a plurality of rod sections 210 that can be detachably connected, when a blade 10 on the pole 200 needs to be used, it can be easily connected. Figure 6 As shown, it is only necessary to lift a fan blade 10 above the fan blade 10 (shown as A in the figure) upward to the upper rod section 210 of the rod section 210 where the desired fan blade 10 is located, and then use the limiting member 300 to clamp the lower end of the upper rod section 210 to limit the other fan blades 10 above, and then separate the rod section 210 where the desired fan blade 10 is located from the rod section 210 above it, and the desired fan blade 10 can be removed. Compared with removing all other fan blades 10 above the desired fan blade 10 from the upper end of the vertical pole 200 one by one before obtaining the desired fan blade 10, the operation is simpler.

[0044] Among them, the length of the rod section 210 can be designed according to the hub thickness of the fan blade 10. If the rod section 210 is too long, it will be inconvenient to separate the rod section 210 where the required fan blade 10 is located from the previous rod section 210 when searching for the required fan blade 10 later. If the rod section 210 is too short, the processing cost will be relatively high. Therefore, the length of the rod section 210 should be such that four fan blades 10 can be strung on it.

[0045] The rod section 210 can be formed by machining a metal rod, or by integrally injecting plastic.

[0046] In one embodiment, if Figure 2 As shown, the plug-in portion 211 includes a threaded column, and the connecting portion 212 includes a threaded hole adapted to the threaded column.

[0047] With this arrangement, two adjacent rod sections 210 can be threadedly connected via the threaded column and the threaded hole, and the connection method is simple and reliable.

[0048] In one embodiment, if Figure 3 As shown, the plug-in portion 211 includes a plug-in post, and the connecting portion 212 includes a connecting hole. The plug-in post and the connecting hole have an interference fit or a snap-fit ​​connection. This arrangement facilitates the rapid connection and separation of two adjacent rod sections 210. When the plug-in post and the connecting hole have an interference fit, the outer diameter of the plug-in post is slightly larger than the inner diameter of the connecting hole. When the plug-in post and the connecting hole are snap-fitted together, a slot can be provided on the inner wall of the connecting hole, and an elastic protrusion can be provided on the outer wall of the plug-in post. When the plug-in post is inserted into the connecting hole, the elastic protrusion on the plug-in post snaps into the slot on the inner wall of the connecting hole.

[0049] In one embodiment, if Figure 1 and Figure 7As shown, the base 100 includes a bottom plate 110 and a positioning block 120. A positioning groove 1101 is provided in the middle of the upper surface of the bottom plate 110. A fixing hole 11011 is provided at the bottom of the positioning groove 1101 for fixing the lower end of the vertical pole 200. The lower end of the positioning block 120 is installed in the positioning groove 1101. The positioning block 120 and the bottom plate 110 can be connected by screws. A through hole 1201 is provided in the middle of the positioning block 120 for the lower end of the vertical pole 200 to pass through.

[0050] Since the vertical pole 200 is relatively long, the rigidity of the connection between the vertical pole 200 and the bottom plate 110 is poor due to the connection and accommodation only by the lower end of the vertical pole 200 and the fixing hole 11011 on the bottom plate 110. In the embodiment of the present application, by providing a positioning block 120, the stability of the vertical pole 200 can be improved after the lower end of the vertical pole 200 passes through the through hole 1201 in the middle of the positioning block 120, and the positioning block 120 acts as a reinforcing rib / rib.

[0051] Among them, the bottom plate 110 can be made of a metal plate. The metal plate is heavier, which makes the base 100 more stable and improves the stability of the entire fan blade placement tooling.

[0052] Furthermore, the size of the bottom plate 110 is larger than that of the fan blade 10 , thereby further improving the stability of the base 100 .

[0053] In one embodiment, if Figure 1 、 Figure 4 and Figure 6 As shown, the clamping member 310 includes a C-shaped clamping ring made of elastic material. One end of the limiting rod 320 is fixed to the side of the outer wall of the C-shaped clamping ring opposite to the opening of the C-shaped clamping ring.

[0054] During use, if the clamping member 310 is installed on the rod section 210, hold the limiting rod 320 and push the opening of the C-shaped clamping ring against the side wall of the rod section 210, and the C-shaped clamping ring can be clamped on the rod section 210; if the clamping member 310 is removed, hold the limiting rod 320 and pull it outward.

[0055] In one embodiment, if Figure 1 and Figure 6 As shown, the lower surface of the base 100 is provided with a magnet 400, a suction cup or a self-adhesive pad.

[0056] By setting a magnet 400 on the lower surface of the base 100, the base 100 can be adsorbed on the iron workbench, thereby improving the stability of the fan blade placement tooling; by setting a suction cup or a self-adhesive pad on the lower surface of the base 100, the stability of the base 100 on the workbench can be improved, thereby preventing the fan blade placement tooling from tipping over during use.

[0057] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible without departing from the spirit of the present invention, and these variations and improvements are within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
