Abstract
The utility model discloses a fan leaf structure, including impeller and blade, the impeller is plastics integrated into one piece, and the shaping of the impeller outside has a plurality of leaf forks, and the leaf fork is for the slope of impeller cross section, and the blade passes through the screw to be connected fixedly with the leaf fork, and the leaf fork root is provided with the location chimb that is used for fixing a position the blade. In this kind of fan leaf structure, impeller and fork adopt plastics integrated into one piece, and the blade passes through the screw to be connected with the fork, makes the blade installation location more convenient, and the fork is difficult to warp, takes place the shake when preventing the fan leaf from rotating, and maintenance and replacement cost are lower.
Description
Technical Field
The utility model relates to a fan assembly structure, especially a fan leaf structure.
Background
A common fan blade structure includes an impeller and blades, and the impeller is connected to the blades through a blade fork. In the prior art, the impeller and the blade fork are made of metal, the blade fork is easy to deform under the action of external force, so that the blades of the fan shake when rotating, the fan cannot be normally used, and the maintenance and replacement cost is high.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a fan leaf structure can avoid the fork to warp, and the shake when preventing the fan leaf from rotating, maintenance and replacement cost are lower.
In order to solve the technical problem, the utility model discloses a fan leaf structure, including impeller and blade, the impeller is plastics integrated into one piece, and the shaping of the impeller outside has a plurality of leaf forks, the leaf fork inclines for the impeller cross section, the blade passes through the screw and is connected fixedly with the leaf fork, and the leaf fork root is provided with the location chimb that is used for fixing a position the blade.
The blade fork is provided with a first positioning protrusion and a second positioning protrusion, and the blade is provided with a first positioning hole and a second positioning hole which are correspondingly matched with the first positioning protrusion and the second positioning protrusion, so that the blade is more accurately installed and positioned.
The back of the impeller is provided with a central shaft hole, a metal sleeve is embedded in the central shaft hole, and the metal sleeve is provided with a fixing screw hole. The impeller is connected with the motor shaft through the metal sleeve, so that the impeller can be prevented from being worn too fast, and the mounting structure is more stable.
The back of the blade fork is provided with a plurality of criss-cross reinforcing ribs; the blade is provided with a groove which is consistent with the shape of the blade. The structure can obviously improve the structural strength of the blade fork and the blade, and prevent the deformation of parts.
The utility model has the advantages that: in this kind of fan leaf structure, impeller and fork adopt plastics integrated into one piece, and the blade passes through the screw to be connected with the fork, makes the blade installation location more convenient, and the fork is difficult to warp, takes place the shake when preventing the fan leaf from rotating, and maintenance and replacement cost are lower.
