Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Please refer to fig. 1 to 6, the utility model discloses a blade, including the air inlet end 210 and the air-out end 220 of setting back to back, the length of air inlet end 210 is greater than the length of air-out end 220, still include windward 230 and leeward 240 of setting back to back, windward 230 is close to the first reinforcing plate 231 of one side fixedly connected with of air inlet end 210, a plurality of first reinforcing strips 232 have been arranged at the interval of one side of first reinforcing plate 231 leeward 230, leeward 240 is close to one side fixedly connected with second reinforcing plate 241 of air inlet end 210, a plurality of second reinforcing strips 242 have been arranged at the interval of one side of second reinforcing plate 241 leeward 240, leeward 240 is close to one side fixedly connected with third reinforcing plate 243 of air-out end 220, a plurality of third reinforcing strips 244 have been arranged at the interval of one side of third reinforcing plate 243 leeward 240.
The utility model discloses an in the embodiment, one side that is close to the air inlet end at the windward side sets up first reinforcing plate, set up first enhancement strip on first reinforcing plate, one side that is close to the air inlet end on the leeward side sets up the second reinforcing plate, set up the second enhancement strip on the second reinforcing plate, one side that is close to the air-out end on the leeward side sets up the third reinforcing plate, set up the third enhancement strip on the third reinforcing plate, the abrasion resistance of blade has been improved, can protect the blade better in fan operation process, can guarantee the long-time stability of moving of fan. The first reinforcing plate, the second reinforcing plate and the third reinforcing plate can be, but are not limited to, wear-resisting plates, and the wear-resisting strength of the blade is further improved. First enhancement strip, second enhancement strip and third enhancement strip can but not be limited to for the build-up welding, have reduced the processing degree of difficulty of blade, are convenient for produce and make the blade. First reinforcing plate passes through welded fastening at the windward side, and second reinforcing plate and third reinforcing plate are all through welded fastening at the leeward side. In fan working process, when the dust granule got into the clearance between the blade, can carry out great impact to one side that windward side and leeward side are close to the air inlet end, when the dust granule goes out from the clearance between the blade, can strike one side that leeward side is close to the air-out end, consequently, strike great position at the dust granule to the blade and strengthen, can avoid the weight of too big increase blade, simultaneously, control blade's manufacturing cost.
Further, the windward side 230 and the leeward side 240 are both cambered surfaces. The blades are streamline, the wind resistance of the blades is reduced, the impact of dust particles on the blades is reduced, and the service life of the blades and the running stability of the fan are guaranteed.
Further, the length direction of the first reinforcing bar 232 is parallel to the length direction of the air inlet end 220. The wear-resisting strength of the blade is improved, and the service life of the blade and the running stability of the fan are ensured.
Further, the length direction of the second reinforcing strip 242 is parallel to the length direction of the air inlet end 220. The wear-resisting strength of the blade is improved, and the service life of the blade and the running stability of the fan are ensured.
Further, the length direction of the third reinforcing bar 244 is parallel to the length direction of the air outlet end 220. The wear-resisting strength of the blade is improved, and the service life of the blade and the running stability of the fan are ensured.
Further, the second reinforcing plate 241 is fixedly connected to the third reinforcing plate 243. The overall strength of the second reinforcing plate and the third reinforcing plate is improved, and the possibility that the second reinforcing plate and the third reinforcing plate are separated from the leeward side in the process of the fan is reduced.
