Background technique
Flabellum is the constituent of desk fan and ceiling fan, by driven by motor, rotates the parts producing wind.But present most of ceiling fan is comparatively large because of flabellum, need take larger space and flabellum easily piles up dust.Along with the requirement of people to clean aesthetic is more and more higher, clean, the little household electric appliance that take up room more and more favored, and foldable ceiling fan due to installing/dismounting inconvenient.For this reason, we provide the scalable ceiling fan of a kind of flabellum, there is flabellum scalable, be not easy to be stained with ash, and save space.
Application number is: the Chinese patent of 201320594732.9, discloses the scalable ceiling fan of a kind of flabellum, comprises, and comprises base, swing pipe, rotating disk, connecting sheet, the first flabellum and the second flabellum, and described swing pipe one end is fixed on base, and the other end fixes rotating disk; Described connecting sheet connects rotating disk and the first flabellum; It is characterized in that: described first flabellum is hollow structure, and the inside is provided with guiding groove and restraining groove; Described second flabellum is hollow structure, and arranged outside has guide pad and limiting stopper; Described second flabellum is arranged in the first flabellum, is fixed on the first flabellum by spring.Ceiling fan is received in the first flabellum when off position to utilize the tractive force of spring to ensure, minimizing takes up room, and is not easy to be stained with ash, during work, under centrifugal action, stretches out from the first flabellum, expands fan blade area, increases pectinid effect.
The deficiency that this patent exists is: because built-in spring will often stretch, be easy to damage in long-term using process, above-mentioned patent is particularly inconvenient when replacing spring, needs to reach in the second flabellum with instrument, and also cumbersome when overall package; Dust easily takes in the second flabellum when retraction by this first flabellum.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of industrial flabellum, and this industrial flabellum can be convenient for changing spring, and easy to assembly.
For achieving the above object, the utility model provides following technological scheme: a kind of industrial flabellum, comprise fan hub, described fan hub outer peripheral surface is provided with some blades equably, described blade comprises first body and the second lamellar body, one end of described first lamellar body is provided with the chute communicated with the other end, described second lamellar body is slidably arranged in chute, the outer peripheral surface of described fan hub is provided with inserting groove, described first lamellar body coordinates with inserting groove grafting, described first lamellar body is interfixed by bolt and fan hub, the diapire of described inserting groove and the inner of the second lamellar body are respectively equipped with the first drag hook and the second drag hook, stretched spring is provided with in described chute, the two ends of described stretched spring are respectively equipped with the retainer ring be socketed on the first drag hook and the second drag hook.
The utility model is preferred: the outer end of described first lamellar body is provided with the mounting groove communicated with chute, is provided with the rubber ring contacted with the second lamellar body in described mounting groove.
The utility model is preferred: described first drag hook and the second drag hook are L-type, and its free end is all inconsistent with the inwall of chute.
The utility model is preferred: described first lamellar body is provided with restraining groove near one end of inserting groove, and restraining groove communicates with chute, and described second lamellar body is provided with limiting stopper, and limiting stopper is slidably arranged in restraining groove.
Compared with prior art, the beneficial effects of the utility model are: after the stretched spring in the first lamellar body has damaged, can to outward winding bolt, first lamellar body is extracted in inserting groove, in the process of taking out, first lamellar body can be gone out from slippage the second lamellar body, thus make both separately, the retainer ring at stretched spring two ends is taken off from the first drag hook and the second drag hook respectively, the retainer ring at new stretched spring two ends is set to respectively on the first drag hook and the second drag hook, again the second lamellar body is turned back to in the first lamellar body, first lamellar body turn back to fix with bolt in inserting groove just passable, blade divides in order to two lamellar bodies by arranging like this, and the first lamellar body can disassemble from fan hub, thus just do not need to reach in chute with instrument when replacing stretched spring, make when replacing stretched spring more convenient, more convenient when overall package.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model industry flabellum embodiment is described further.
A kind of industrial flabellum, comprise fan hub 1, described fan hub 1 outer peripheral surface is provided with some blades 2 equably, described blade 2 comprises the first lamellar body 3 and the second lamellar body 4, one end of described first lamellar body 3 is provided with the chute 5 communicated with the other end, described second lamellar body 4 is slidably arranged in chute 5, the outer peripheral surface of described fan hub 1 is provided with inserting groove 6, described first lamellar body 3 coordinates with inserting groove 6 grafting, described first lamellar body 3 is interfixed by bolt 7 and fan hub 1, the diapire of described inserting groove 6 and the inner of the second lamellar body 4 are respectively equipped with the first drag hook 8 and the second drag hook 9, stretched spring 15 is provided with in described chute 5, the two ends of described stretched spring 15 are respectively equipped with the retainer ring 10 be socketed on the first drag hook 8 and the second drag hook 9.
By adopting technique scheme, after the stretched spring 15 in the first lamellar body 3 has damaged, can to outward winding bolt 7, first lamellar body 3 is extracted in inserting groove 6, in the process of taking out, first lamellar body 3 can be gone out from slippage the second lamellar body 4, thus make both separately, the retainer ring 10 at stretched spring 15 two ends is taken off from the first drag hook 8 and the second drag hook 9 respectively, the retainer ring 10 at new stretched spring 15 two ends is set to respectively on the first drag hook 8 and the second drag hook 9, again the second lamellar body 4 is turned back to in the first lamellar body 3, first lamellar body 3 turns back to the interior bolt 7 of inserting groove 6 and fixes just passable, arranging 2 points, blade in order to two lamellar bodies like this, and the first lamellar body 3 can disassemble from fan hub 1, thus just do not need to reach in chute 5 with instrument when replacing stretched spring 15, make when replacing stretched spring 15 more convenient, more convenient when overall package.
The outer end of described first lamellar body 3 is provided with the mounting groove 11 communicated with chute 5, is provided with the stretched spring 12 contacted with the second lamellar body 4 in described mounting groove 11.
By adopting technique scheme, when flabellum stops operating time, the second lamellar body 4 bounces back, and in the process of retraction, stretched spring 12 can carry out wiping to its surface, can effectively prevent dust from bringing in chute 5.
