Seeing also Fig. 1～Fig. 6, is the selected example structure of the utility model shown in the figure.
Present embodiment provides the fixing device of a kind of ceiling fan blade and vane frame, and it comprises:
One blade 1, it has at least two perforation 11 in an end.As seen from the figure, the blade 1 in present embodiment is to have three perforation 11, and three are bored a hole 11 with rounded projections arranged.
One vane frame 2, it has 11 the portion that wears 21 of respectively boring a hole that correspondence is inserted blade 1, and respectively wears portion 21 and have a stop part 211 in an end that wears and expose to perforation 11.In the present embodiment, this wears portion 21 and respectively is stand-alone assembly, and is fixed on the vane frame 2 in the spiral shell mode of establishing.Certainly, structurally also can be one-body molded in processing procedure with vane frame 2.
At least one locating piece 3, it establishes a limited part 31 respectively with the corresponding position that respectively wears portion 21, and each stop part 211 is to pass this perforation 11, and stopped by corresponding limited part 31 and pin down mutually and locating blade 1 and vane frame 2, at least one limited part 311 in several limited parts 31 is movable and can contracts inwardly and overhanging with respect to locating piece 3, locating piece 3 with this movable limited part 311 in overhanging with in when contracting, stop and break away from corresponding stop part 211 respectively, with the location of control vane frame 2 and blade 1 with separate.
As Fig. 4～shown in Figure 6, in the present embodiment, each stop part 211 comprises one first stop part 211a, and locating piece 3 stretches out on the blade 1 with each first stop part 211a, for stopping the substantially horizontal displacement of each corresponding limited part 31 with respect to blade 1; Each stop part 211 also comprises one second stop part 211b, it is to pass perforation 11 in the portion of wearing 21, and place 1 in this second stop part 211b and blade, and stopped by the limited part 21 on the blade 1, and 21 of each limited parts stop corresponding stop part 21 respectively in the opposite direction.
Employed locating piece 3 quantity are 1 in the present embodiment, certainly, can cooperate marriage relation decision locating piece 3 quantity of 2 of blade 1 and vane frame.
This movable limited part 311 is the middle positions that are positioned at locating piece in the present embodiment, and locating piece 3 has fixed limited part 312 in addition, this fixed limited part 312 is to be located in two ends, and movable and fixed limited part the 311, the 312nd is oppositely arranged in different spacing directions, for example in the present embodiment, fixed limited part 312 is to be embedded at the portion of wearing 21 towards these movable limited part 311 opposite directions, pins down mutually whereby in limited part 311,312 and when wearing portion 21 location.
Movable limited part 311 at locating piece 3 has a body of rod 311a, and be located in the containing groove 32 of locating piece 3 and overhanging with in contract, and body of rod 311a is in overhanging and be positioned the blocking position of stop part 211, to cooperate fixed limited part 312 locating blade 1 and vane frame 2.
The width of this stop part 211 is greater than these 11 external diameters of boring a hole, and the fixed limited part 312 of this locating piece 3 is to be embedded at 1 in stop part 211 and blade, and the body of rod 311a end of this movable limited part 311 outside containing groove 32 is pivoted with an Embedded Division 311b, to embed 1 in stop part 211 and blade.
This fixed limited part 312 is towards locating piece indent and curved, and this Embedded Division 3
11a also has indent and curved structure, fixed limited part 312 and this Embedded Division 311a, and the two is to accord with the first corresponding stop part 211a in 1 embedding of the second stop part 211b and blade.
This movable positioning part 311 is provided with a driving lever 311c in body of rod 311a, locating piece 3 has one and accords with driving lever 311c and stir the elongate slots 33 that direction is offered, and offer a restraining groove 34 that is communicated with and stops driving lever 311c with it in elongate slots 33 sides, this restraining groove 34 is opened in the driving lever 311c position that this Embedded Division 311b embeds stop part 211.
See also Fig. 4～Fig. 6, in the present embodiment, it is the perforation 11 of the portion that wears 21 of this vane frame 2 being passed blade 1, the stop part 211 of the portion's of wearing 21 ends is exposed to outside the blade 1, and this locating piece placed 21 in the portion that respectively wears, and make fixed limited part 312 be embedded at the corresponding portion that wears 21 and be positioned 1 in its stop part 211 and blade.Afterwards, again the end is provided with the body of rod 311a of Embedded Division 311b, towards wearing portion 21 positions, makes this Embedded Division 311b be positioned 1 in stop part 211 and blade by stirring this driving lever 311c, again with driving lever 311c in relative position is pulled restraining groove 34, and restriction body of rod 311a is in this position.Therefore, when the limited part 31 of locating piece 3 is positioned 1 in the portion of wearing 21 and blade, as the limited part 31 that touches even push locating piece 3 accidentally, then, locating piece 3 can not come off owing to making each limited part 31, and limited part as shown in the figure 311 and two limited parts 312 provide rightabout stopping, therefore can be provided in respectively to wear 21 effects that pin down mutually of portion.
Structure with present embodiment is an example, when blade 1 is outwards taken out with respect to vane frame 2, stop by this two limited part 312, and when blade 1 pushes away in respect to vane frame 2, then can stop, so can not cause as having equidirectional stopping between the blade of prior art and vane frame and may cause the problem that comes off accidentally by this limited part 311.
So be not difficult to find that by above-mentioned explanation major advantage of the present utility model is, the simple and easy combining structure of blade and vane frame be provided, and have and avoid blade to break away from the Security of vane frame accidentally.
Certainly, still there are many examples in the utility model, therebetween the only variation on the details.See also Fig. 7, Fig. 8, it is second embodiment of the present utility model, wherein this locating piece 3 also has one and accords with driving lever 311c and stir the elongate slots 33 that direction is offered, and places in the containing groove 32 with an elastic top support member 4, and body of rod 311a end is shored towards wearing portion's 21 directions.
By above-mentioned structure as seen, the body of rod 311a of present embodiment is when stretching out, be that elastic top support member 4 in itself and the containing groove 32 is towards wearing portion's 21 application of forces, make so before using, only need stir driving lever 311c earlier and to contract in the body of rod 311a, when locating piece 3 is decontroled driving lever 311c during in the appropriate location, and body of rod 311a is stretched out and make Embedded Division 311b embed 1 in stop part 211 and blade, to reach the effect identical with first embodiment.
See also Fig. 9, Figure 10, it is the 3rd embodiment of the present utility model, wherein this stop part 211 is holes, this fixed limited part 312 is to be convexly equipped with one for inserting cylinder 312a in the stop part 211 (hole) towards stop part 211 directions respectively, and 311 of this movable limited parts to have a cylinder 311d in body of rod 311a overhanging and penetrate in the stop part 211 (hole) with respect to containing groove 32.
In the present embodiment, also can be and between the body of this limited part 311 and locating piece 3 as first embodiment, cooperate restraining groove 34 and location body of rod 311a all can cooperate the limited part 311d of present embodiment and 312a to reach the effect as the first two embodiment with driving lever 311c in containing groove.
See also Figure 11, Figure 12, it is the 4th embodiment of the present utility model, wherein, be limited part 311d, 312a and stop part 211 (hole) with the 3rd embodiment, and the utilization as second embodiment's elastic component 4, in this containing groove 32, shore body of rod 311a, to reach embodiment's identical effect as described above.
