Abstract
The utility model belongs to the technical field of micromotor appliances, particularly relates to a fan blade support of a micromotor, and discloses the fan blade support of the micromotor. The fan blade support of the micromotor comprises a plate body, wherein the front side of the plate body is round, a round sinking part is formed in the middle of the plate body, a round boss is arranged in the middle of the round sinking part, a fan blade fixing head is connected onto the back side of the plate body, the fan blade fixing head is a circular-truncated-cone-shaped piece which gradually shrinks from top to bottom, triangular connecting frames are arranged between the fan blade fixing head and the back side of the plate body, a through hole is formed in the central axis of the fan blade fixing head, the through hole is communicated with an axial hole, a clamping slot is formed in the lower part of the fan blade fixing head, and the clamping slot is in arc transition with the lower part of the fan blade fixing head. According to the fan blade support of the micromotor, the fan blade support is fixed on a rotating shaft and does not fall off in the high-speed operation, so that the safety of the motor is improved.
Description
Technical field
The utility model belongs to micro motor apparatus technical field, relates in particular to a kind of fan blade holder of micro motor.
Background technique
The holder of micro motor fan blade is the important composition parts of micro motor, and its main effect is to hold fan page.Current micro motor fan blade holder, in the process of installing, is designed to fan blade head the size of rotating shaft, is arranged in rotating shaft.This type of design, the stipule of just keeping watch is set in rotating shaft, and such design makes, in process that motor runs up, easily to cause fan blade coming off from rotating shaft, affects performance and the Security of motor.And the design of fan blade holder exists defect, fan blade holder is simple being set in rotating shaft, is easy to come off.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of fan blade holder of micro motor is provided, and its technological scheme is as follows:
A fan blade holder for micro motor, is characterized in that, the fan blade holder of described micro motor comprises plate body, the front of plate body is circular, the middle of plate body offers circular depression, and the middle of circular depression is provided with round boss, and the middle of round boss offers axis hole; The edge of plate body is evenly distributed with some holder posts, and the top of holder post is arc convex; The back side of plate body is connected with fan blade gland, fan blade gland is a truncated cone part from top to bottom shrinking gradually, between fan blade gland and the plate body back side, be provided with triangle connecting rack, on the central axis of fan blade gland, offer through hole, described through hole communicates with axis hole, the bottom of fan gland offers draw-in groove, and draw-in groove and bottom fan blade gland are arc transition.
The utility model when in use, rotating shaft plug with axis hole and through hole draw-in groove in, the bottom of rotating shaft is provided with fastener, and together with the draw-in groove of fan gland fastens with fastener, has played the effect of fixing fan blade holder.Triangle connecting rack can well make whole fan blade holder more stable, there will not be slight crack in high speed rotating.
Model utility can make fan blade holder be fixed in rotating shaft, is unlikely to come off in running up, and improves the Security of motor.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
