Abstract
The utility model discloses a waterproof fan blade of axial closed, including the fan blade body, with the integrative injection moulding's of fan blade body a plurality of fan blades, install the hollow mandrel at the inside center of fan blade body, the top surface of fan blade body is no trompil plane or curved surface enclosed construction, set up first mounting hole on the lateral wall of fan blade body, has seted up the second mounting hole corresponding with first mounting hole on hollow mandrel's the lateral wall, injection moulding of hollow mandrel and fan blade body and fan blade, the built -in screw rod that is used for locking motor shaft that is equipped with of second mounting hole. Need not offer the mounting hole at fan blade body top, when the fan blade body is installed, during motor shaft inserts hollow mandrel perpendicularly, then adopt the fastener be the enclosed construction with motor shaft and hollow mandrel fixed connection, fan blade body top up, this internal and flow into in the motor and emergence electric leakage accident along motor shaft effectively to prevent water from to get into the fan blade from the trompil at fan blade body top.
Description
Technical field
This utility model is related to fan technology field, more specifically, is to be related to a kind of axial enclosed waterproof fan blade.
Background technology
Fan is widely used in the productive life of people, and for aerofluxuss, radiating etc., and fan blade is the important portion in fan
Part.But the fan blade bodies top of traditional fan blade is generally offered for installing the perforate of machine shaft, fan blade body during installation
In horizontally disposed, machine shaft is horizontally inserted in the perforate of fan blade body, then using securing member by machine shaft and fan blade
Body is fixedly connected, and as motor and fan blade body are in being horizontally disposed with, water typically will not be from the perforate of fan blade bodies top
In vivo and flow into along motor along machine shaft and electric leakage accident occurs into fan blade sheet.If fan blade body is installed upward, motor
Rotating shaft is horizontally inserted in the perforate of fan blade body, then machine shaft is fixedly connected with fan blade body using securing member, electricity
Machine is under fan blade, and as motor shaft needs to rotate, the axial direction of motor is difficult to nature sealing, when outdoor use, easily leads
Water is caused fan blade sheet to be entered from the perforate of fan blade bodies top in vivo and is flowed in motor along machine shaft and electric leakage accident is occurred.
Therefore, easily cause, cause electric leakage accident.Therefore traditional fan blade should not adopt the installation upward of fan blade body
Mode.
Utility model content
The purpose of this utility model is to overcome drawbacks described above of the prior art, there is provided a kind of fan blade bodies top is envelope
Close structure, during the installation upward of fan blade body, can effectively prevent water from fan blade sheet is entered from the perforate of fan blade bodies top internal
And flow in motor along machine shaft and a kind of axial enclosed waterproof fan blade of electric leakage accident occurs.
For achieving the above object, the technical scheme that this utility model is provided is as follows：
A kind of axial enclosed waterproof fan blade, including fan blade body are provided, if the dry tablet with fan blade body integrated injection molding
Fan blade, is installed in the hollow mandrel at fan blade body interior center, and the top surface of the fan blade body is to seal without perforate plane or curved surface
Structure is closed, the first installing hole on the side wall of the fan blade body, is offered, is offered on the side wall of hollow mandrel and is installed with first
The second corresponding installing hole of hole, the hollow mandrel and fan blade body and fan blade single injection-molded, the second installing hole are built-in
It is provided with the screw rod for locking motor rotating shaft.
As preferred, in above-mentioned technical proposal, the fan blade is originally injection molded with several reinforcements in vivo.
Compared with prior art, the beneficial effects of the utility model are：By being nothing into top surface by fan blade body design
Perforate plane or curved surface enclosed construction, offer the first installing hole, on the side wall of hollow mandrel on the side wall of the fan blade body
Second installing hole corresponding with the first installing hole is offered, the hollow mandrel is once molded into fan blade body and fan blade
Type, is equiped with the screw rod for locking motor rotating shaft in the second installing hole.Installing hole, wind are opened up in fan blade bodies top without needs
When leaf body is installed upward, machine shaft is perpendicularly inserted in hollow mandrel, then using securing member from side by machine shaft
It is fixedly connected with hollow mandrel, fan blade bodies top is enclosed construction, can effectively prevent water from the perforate of fan blade bodies top
In vivo and flow into along motor along machine shaft and electric leakage accident occurs into fan blade sheet.
With reference to the accompanying drawings and examples a kind of axial enclosed waterproof fan blade described in the utility model is made furtherly
It is bright.
Description of the drawings
Fig. 1 is a kind of one of three-dimensional structure diagram of axial enclosed waterproof fan blade described in the utility model；
Fig. 2 is the two of the three-dimensional structure diagram of a kind of axial enclosed waterproof fan blade described in the utility model；
Fig. 3 is a kind of rearview of axial enclosed waterproof fan blade described in the utility model.
Specific embodiment
A kind of preferred example of axial enclosed waterproof fan blade described in the utility model is the following is, therefore this reality is not limited
With new protection domain.
Fig. 1, Fig. 2 and Fig. 3 are refer to, a kind of axial enclosed waterproof fan blade, including fan blade body 1 is shown in figure, with wind
If the dry tablet fan blade 2 of 1 integrated injection molding of leaf body, the hollow mandrel 3 of 1 inside center of fan blade body, the fan blade are installed in
The top surface of body 1 is, without perforate plane or curved surface enclosed construction, the first installing hole 4 to be offered on the side wall of the fan blade body 1,
Second installing hole 5 corresponding with the first installing hole 4, the hollow mandrel 3 and fan blade sheet are offered on the side wall of hollow mandrel 3
2 single injection-molded of body 1 and fan blade, is equiped with the screw rod 6 for locking motor rotating shaft, without needs in wind in the second installing hole 5
Installing hole is opened up at the top of leaf body 1, when fan blade body 1 is installed upward, in hollow mandrel 3, then machine shaft is perpendicularly inserted into
Machine shaft is fixedly connected with hollow mandrel 3 from side using securing member, is enclosed construction at the top of fan blade body 1, can be effective
Prevent water from fan blade sheet is entered from the perforate on 1, fan blade body top in vivo and is flowed into along motor along machine shaft and electric leakage thing is occurred
Therefore.
Preferably, in the present embodiment, several reinforcements 7 are injection molded with the fan blade body 1, so as to increase
The intensity of high wind leaf body 1.
Above-described embodiment is this utility model preferably embodiment, but embodiment of the present utility model is not by above-mentioned
The restriction of embodiment, it is other it is any without departing from the change made under spirit of the present utility model and principle, modify, replace
Generation, combination, simplification, should be equivalent substitute mode, are included within protection domain of the present utility model.
