Description
Technical field
The present invention is about a kind of wind dispelling device, especially a kind of blade for ceiling fan.
Background technique
Ceiling fan is due to not only preventing take up ground space, but also has good air agitation effect, widely public to be used.It is existing
Some ceiling fans have a shaft, a wheel hub, multiple blades and multiple safety cables.The wheel hub is rotatably engaged in the shaft；It should
Multiple blades are respectively provided with a first end and a second end, which is linked to the wheel hub, the first end and the second end it
Between be communicated with a channel；Multiple safety cable is respectively arranged in the channel of each blade, and each safety cable one end is connected to the wheel hub,
Each safety cable other end is positioned at the second end of each blade.It whereby, can by each safety cable when which rotates
Setting, falls ground prevent leaf destruction or to be detached from the wheel hub.
However, safety cable must be stretched through by the first end of blade when assembling each blade and each safety cable, pass through the logical of blade
In the second end of blade, process is more time-consuming and inconvenient for repositioning behind road.For large-scale ceiling fan, to be applicable in big face
Certain air quantity can be maintained when product space, the length of blade of the large size ceiling fan is longer；When so that assembling each blade and each safety cable
More time-consuming work consuming causes inconvenience in operation, while also causing the convenience of overall package and efficiency bad.
In view of this, existing blade for ceiling fan still has improvedd necessity really.
Summary of the invention
To solve the above problems, it is direct for safety cable to wear ditch equipped with one the object of the present invention is to provide a kind of blade for ceiling fan
It is placed in channel, to promote the effect of assembling convenience.
Present invention directionality as described below or its approximate term, for example, "front", "rear", " upper (top) ", " under (bottom) ",
"inner", "outside", " side " etc., the direction of Primary Reference attached drawings, each side's tropism or its approximate term are only to aid in illustrating
And understand various embodiments of the present invention, it is non-to limit the present invention.
Blade for ceiling fan of the invention, comprising: a blade body, with an opposite proximal ends and a distal shaft end；
One channel extends to the distal shaft end by the proximal ends；And one worn ditch, positioned at the upside or downside of the blade body, this is worn
Ditch extends to the distal shaft end by the proximal ends, this is worn ditch and is connected to the channel.
Therefore, blade for ceiling fan of the invention extends to the distal shaft end by the proximal ends using the channel, and this wears ditch connection
The channel；It is intended to assemble the safety cable when blade for ceiling fan, this is worn ditch and can laterally stretch through for the safety cable, makes the safety cable can
Ditch is worn by this and is directly placed in the channel, is stretched through, to avoid there is the safety cable by the proximal ends of the blade body again by being somebody's turn to do
Channel is pulled to not being easily assembled and the problem of time-consuming work consuming of the distal shaft end.When assembling whereby, can be promoted and dismantling the safety cable
Operation ease and efficiency, meanwhile, suitable for the large-scale ceiling fan of particular/special requirement.
Wherein, the blade body is integrally formed, which has one to be connected in the short side direction portion windward
With a diversion division, which is formed in this windward in portion, this is worn ditch and is located at portion and the diversion division connection windward.Such as
This, has effects that operation smooth degree when promoting the blade body and safety cable combination.
Wherein, on the short side direction of the blade body, the blade body have first length, this windward portion with should
Diversion division connection to this windward portion far from the diversion division one end distance be second length, second length this first
1/5-3/5 times of length.In this way, can reduce the overall weight of the blade body, have effects that promote ceiling fan rotation efficiency.
Wherein, the first end with second end in the portion windward do not connect to form this and wear ditch.In this way, the simple structure and be convenient for
Assembling has effects that reduce manufacturing cost.
Wherein, which is connected with the second end integrated molding in the portion windward, the diversion division and this windward portion the
This is formed between one end and wears ditch, this wears the upside that ditch is located at the blade body.In this way, user is under blade for ceiling fan of the present invention
Side can't see this and wear ditch, and the blade for ceiling fan is made to have the effect of more complete appearance.
Wherein, which is connected with the second end integrated molding in the portion windward, the diversion division and this windward portion the
This is formed between one end and wears ditch, this wears the downside that ditch is located at the blade body.In this way, have can reduce dust by this wear ditch into
The effect of entering the channel.
Wherein, which is equipped with multiple lockholes at the neighbouring proximal ends.In this way, the blade body can be promoted by having
With locking item linking steady character the effect of.
It wherein, separately include an at least reinforcement rib, which connects the inner wall opposite in portion windward.
In this way, having effects that can be promoted the structural strength in the portion windward.
