Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1 to Fig. 5, a kind of fan blade device assembly, what comprise axle bed 1 and be arranged at axle bed 1 drives axle 2, also comprise fan blade 3, described fan blade 3 is provided with blocked hole 32, described upper end of driving axle 2 is stretched out axle bed 1 and is connected with deck 4, and described fan blade 3 is by blocked hole 32 and deck 4 clamping, and the bottom of described deck 4 is connected with the spring support 5 for supporting fan blade 3.In most of the cases, due to fan blade 3 take up space larger, for the ease of packaging, carry and the consideration such as transport, fan blade 3 generally can be pulled down, when this fan blade 3 assembly of devices uses, the blocked hole 32 of fan blade 3 is aimed at deck 4 and is inserted in, when being inserted in bottom deck 4, make fan blade 3 compress spring support 5, then carry out rotating and eliminate the pressure compressing spring support 5 and fan blade 3 and deck 4 can be made to be formed connect and fix; When dismantling, fan blade 3 being compressed spring support 5 downwards again, then reversely rotates, making the clamping between fan blade 3 and deck 4 misplace thus remove clamping relation, take off fan blade 3.
As can be seen from the action of above-mentioned mounting or dismounting fan blade 3, this fan blade 3 assembly of devices in use, directly fan blade 3 and deck 4 are carried out clamping quickly and easily fan blade 3 to be arranged on and to drive on axle 2, without the need to instrument and screw etc. during installation, structure is simple, easy to assembly, simultaneously, dismounting is also suitable easy, and owing to not needing scattered finding to assemble, so, also can not there is the phenomenons such as screw loss.
Certainly, in order to improve the structure of this fan blade 3 assembly of devices further, described bottom of driving axle 2 is connected with driving mechanism 6, described driving mechanism 6 comprises the first gear 61, second gear 62 and drive motors 63, described first gear 61 with drive axle 2 and be fixedly connected with and engage with the second gear 62, described second gear 62 is arranged on the output shaft of drive motors 63.During work, drive motors 63 drives the second gear 62 to rotate, and the second gear 62 drives the first gear 61, makes to drive axle 2 and realizes rotating, drive axle 2 and drive fan blade 3 further.Utilize the assembly structure after improving further in this programme, the versatility of this assembly of devices can be made stronger.
In the technical program, described blocked hole 32 is provided with the first screens 33, and described deck 4 is provided with the second screens 41 be mutually engaged with the first screens 33; Described first screens 33, second screens 41 is L shape or " J " font.When assembling, the first screens 33 is engaged mutually with the second screens 41, thus deck 4 and fan blade 3 compact siro spinning technology are fixed, and wherein the first screens 33, second screens 41 is L shape for best, and this shape is convenient.
In the technical program, described spring support 5 comprises discshaped body 51, and described discshaped body 51 is provided with at least two shell fragments 62.Described discshaped body 51 can be that plastic material is one-body molded with shell fragment 62, certainly, when shell fragment 62 is metal, the structure be embedded also can be adopted to be connected with discshaped body 51, all can realize elastic reset effect.
In the technical program, described deck 4 is provided with through hole 42, described in drive axle 2 and be provided with first through hole 21 corresponding with through hole 42, described deck 4 utilizes screw bolt passes through hole 42, first through hole 21 and drives axle 2 and be fixedly connected with.This connected mode utilizing bolt will drive axle 2 and deck 4, its structure is more reliable, and drive axle 2 when rotating, the output of moment of torsion can respond faster on fan blade 3, and can extenuate and bear larger torsional forces between fan blade 3 and deck 4.
In the technical program, one end of described fan blade 3 is provided with the first mark 31, and the upper surface of described deck 4 is provided with the second mark 43.It is corresponding setting that this first mark 31 and second identifies 43, better can identify, preventing the phenomenons such as dislocation, misloading when assembling.
Meanwhile, the upper end of driving axle 2 described in is also connected with end cap 7.This end cap 7 can play the effects such as dust-proof, waterproof, has preferably decorative effect concurrently.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
