[ detailed description ] embodiments
A fan used on a stealthy fan lamp is disclosed as figures 1 to 6, and comprises a blade frame disc 1, a fan synchronizing gear 2 arranged in the middle of the blade frame disc 1, at least three blade mounting gears 3 and fan blades 4, and a reset piece (not shown in the figure) for resetting the fan blades 4, wherein the reset piece can be a tension spring with one end connected to the middle of the blade frame disc 1 and the other end connected with the blade mounting gears 3, or a torsion spring directly arranged on the blade mounting gears 3; the end of the fan blade 4 is locked and installed on the blade installation gear 3 through a fastener; a plurality of mounting holes 11 for mounting the blade mounting gear 3 are formed in the periphery of the blade carrier disc 1, in the present embodiment, there are four blade mounting gears 3 and four fan blades 4, there are also four mounting holes 11 in the blade carrier disc 1, and the mounting holes 11 are uniformly distributed in the peripheral position of the blade carrier disc; at least two elastic hooks 31 are arranged on each blade mounting gear 3, and the elastic hooks 31 on the blade mounting gears 3 are hooked on the blade frame disc 1 after the blade mounting gears 3 penetrate through corresponding mounting holes on the blade frame disc 1.
The utility model discloses when the equipment, earlier install fan synchromesh gear 2 on the middle part position of blade frame dish 1, pass the back from the corresponding mounting hole of blade frame dish 1 one by one with all blade installation gears 3 after that, make their elasticity in each other hold hook 31 and collude on blade frame dish 1, make their gear in each other mesh with the gear on the fan synchromesh gear 2 simultaneously, reuse fastener (screw, bolt etc.) is installed fan blade 4 locking one by one on blade installation gear 3 at last, accomplish with this the utility model discloses the equipment of each part.
It can be seen from the above that all the blade mounting gears 3 are mounted by hooking the elastic hooks 31 arranged on the blade mounting gears on the blade frame disc 1, and then the blade mounting gears 3 are not required to be fixed by hands when each fan blade 4 is mounted one by one, and the mounting of the fan blades 4 can be completed by directly locking the fastening piece by a tool, so that the whole fan is more convenient and quicker to assemble, and the production efficiency is greatly improved.
In the daily use process of the fan blades 4, the fan blades are continuously opened or closed to generate friction on the blade mounting gear 3, the blade mounting gear 3 is abraded after a long time, in order to avoid the abrasion, as shown in fig. 7, a wear-resistant gasket 5 is further arranged on the upper surface of the blade mounting gear 3, and the fan blades 4 are mounted on the blade mounting gear 3 and then are in contact with the wear-resistant gasket 5.
In the present embodiment, as shown in fig. 1 to 5 and 8 to 12, the fan synchronizing gear 2 is composed of a ring-shaped plate 21 and a plurality of sections of teeth 22 uniformly distributed on the side wall of the ring-shaped plate 21; the gear on the blade mounting gear 3 is an arc-shaped gear 32, two sides of the arc-shaped gear 32 are respectively provided with a blade opening limiting gear 33 and a blade folding limiting gear 34, and two sides of each section of gear on the fan synchronizing gear 2 are respectively provided with an opening limiting stop 23 and a folding limiting stop 24 which are used for the blade opening limiting gear 33 and the blade folding limiting gear 34 on the corresponding blade mounting gear 3 to contact; an arc-shaped pressing block 35 capable of pressing on the corresponding section of teeth on the fan synchronous gear 2 is arranged on the side wall of the blade mounting gear 3 below the arc-shaped teeth 32. Then the utility model discloses when the equipment, earlier place fan synchronizing gear 2 on the middle part position of blisk 1, install all blade installation gears 3 one by one on corresponding mounting hole 11 of blisk 1 after that, and make that the arc tooth 31 on their own lateral wall and fan synchronizing gear 2 on corresponding that section tooth meshing, arc briquetting 35 on every blade installation gear 3 can press on fan synchronizing gear 2 corresponding that section tooth simultaneously, with this will install fan synchronizing gear 2 on the middle part position of blisk 1. Can see, the utility model discloses saved the process that traditional stealthy fan need install fan synchromesh with a plurality of connecting pieces, thereby makeed the utility model discloses an equipment is simpler, and is swift, has further improved production efficiency.
In a normal state of the utility model, as shown in fig. 1 to 3, all the fan blades 4 are folded and hidden on the upper surface of the blade frame disc 1, and at this time, the blade folding limit teeth 34 on the blade mounting gear 3 are in contact with the folding limit baffle table 24 on one side of the section of corresponding teeth of the fan synchronizing gear 2; when people need to use the fan, the blade frame disc 1 starts to rotate, then all the fan blades overcome the acting force of the reset piece under the action of centrifugal force to be opened outwards, so that the corresponding blade mounting gears 3 are driven to rotate, and at the moment, all the fan blades 4 are simultaneously opened outwards under the action of the fan synchronous gear 2; when the blade opening limit teeth 33 on the blade mounting gear 3 rotate to contact the opening limit stop 23 on the other side of the section of teeth corresponding to the fan synchronizing gear 2 (as shown in fig. 11 and 12), the fan blades 4 cannot be opened outwards any more, and at this time, the fan blade carrier disk 1 can be continuously rotated to achieve the blowing effect. When the fan is not used, the blade frame disc can be slowly stopped, the centrifugal force can be slowly reduced, and the fan blades can be reset under the action of the reset piece until the fan is restored to the normal state. It can be seen that, in the process that the fan blades 4 are opened under the action of centrifugal force, the blade mounting gear 3 rotates to enable the blade opening limiting teeth 33 to slowly rotate to be in contact with the opening limiting baffle table 23 on one side of the section of teeth corresponding to the fan synchronizing gear 2, and at the moment, the fan blades 4 cannot be opened outwards any more (namely, the blades are completely opened); similarly, when the fan blades 4 are folded under the action of the reset piece, the blade folding limit teeth 34 can slowly rotate back to the folding limit stop 24 on the other side of the section of teeth corresponding to the fan synchronous gear 2 to contact, and at the moment, the fan blades are completely folded and hidden on the blade frame disc 1; that is, the blade opening limit teeth 33 and the blade retracting limit teeth 34 function to limit the outward opening and inward retracting of the fan blades, respectively.
In summary, the preferred embodiments of the present invention are not intended to limit the scope of the present invention, and all equivalent changes and modifications made according to the content of the claims of the present invention should belong to the technical scope of the present invention.
