Abstract
The invention belongs to the technical field of micromotor tools, and particularly relates to a blade support of a micromotor. The blade support of the micromotor comprises a plate body, wherein the front surface of the plate body is in a circular shape, the middle part of the plate body is provided with a circular recess part, and the middle part of the circular recess part is provided with a circular lug boss; a triangular connecting rack is arranged between a blade fixed head and the back surface of the plate body; a through hole is formed along the central axis of the blade fixed head and is communicated with an axle hole; a clamping groove is formed in the lower part of the blade fixed head, and the clamping groove and the lower part of the blade fixed head are in arc transition. The blade support disclosed by the invention is fixed on a rotating shaft and is unlikely to drop during high-speed operation, thereby enhancing the safety of the micromotor.
Description
Technical field
The invention belongs to micro motor apparatus technical field, relate 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 object of the invention is to solve above-described technical problem, a kind of fan blade holder of micro motor is provided, 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 present invention 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.
The present invention 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 invention.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
