Abstract
The utility model relates to an electric fan, particularly spring power fan, composed of fan blades, a power and speed changing mechanism. The fan blades are installed on a fan shaft which is connected with a power shaft through the speed changing mechanism, wherein, a mainspring spring is arranged on the power shaft, and one end of the power shaft is provided with a handle. The mainspring spring can be screwed by rotating the handle, so that the spring can store energy; when the handle is loosened, the mainspring spring can drive the power shaft, the fan shaft can be rotated through the speed changing mechanism, and the fan can be operated. Accordingly, the fan can be rotated without electricity. The utility model has the advantages of electricity saving, high safety and convenience. The utility model which is free from the restriction of electricity can be used at any time and at any site.
Description
The utility model relates to a kind of electric fan, specifically is Spring power fan.
Fan on the market all is to adopt electric power as the energy without exception now.Though this fan is simple to operate, and is multiple functional, it must be could use under the situation that electricity is arranged.And always holding in the palm a long electric wire, neither attractive in appearance, inconvenient again, when fan is far away apart from power supply, just must connect power supply by one even several wire board, as long as and a bad connection arranged, fan just can not change, and makes the people feel reliable inadequately, also lacks Security.In the place that does not have power supply or electricity consumption inconvenience and the restricted place of electricity consumption (as students' dormitory, field etc.), people can only hope electric fan and heave a sigh.
The purpose of this utility model just provides a kind of Spring power fan, and it does not need power supply, but adopts spring as power, and power saving is safe and reliable, especially can almost use whenever and wherever possible without restriction, to satisfy people's needs.
The technical solution of the utility model is made up of flabellum, power and gear, and flabellum is contained on the fan shaft, and fan shaft connects with line shaft by gear, it is characterized in that being equipped with on line shaft clockwork spring, and line shaft one end is equipped with handle.
According to technique scheme, thereby tighten clockwork spring by handle rotational power axle, make the spring stored energy, when handle turns to a certain degree, clockwork spring is in the state of screwing, when spring stores enough energy, and release handle, clockwork spring just drives line shaft and makes fan shaft rotation, fan work by gear.Like this, need not electric power, can make fan rotation, not only can power saving, safe and reliable, not can use by the restriction of electric power whenever and wherever possible, very convenient, to satisfy people's needs.
On the line shaft between line shaft of the present utility model and the gear, ratchet mechanism is housed, like this, ratchet mechanism makes line shaft a direction to rotate, the direction that promptly tightens clockwork spring is rotated, and simultaneously, line shaft is when tightening the clockwork spring rotation, can not drive gear and fan rotates, like this, when tightening clockwork spring, very laborsaving by handle rotational power axle.
The utility model is equipped with knob at an end of fan shaft, constitutes assistant starting mechanism.Handle with sleeve promptly tightens clockwork spring, does not start entire mechanism if clockwork spring tightens the back for the moment by line shaft, can pass through the knob fan shaft, and assistant starting makes fan reliably working under the driving of clockwork spring.
Handle of the present utility model is that be made of interior bar and overcoat can adjustable structure, and rotary joint is housed on the handle.Like this, during handle with sleeve,, can reach the labour-saving purpose, not the time spent, handle be shortened the handle elongation.Joint on the handle can make handle stretch and use, and is perhaps folding.
The stop cap is housed on the gear of the present utility model, and when clockwork spring tightens, drive fan is rotated, carry out work, when not needing fan work, the stop cap on the gear is pressed, fan is quit work, and the energy on the clockwork spring use in order to continuing behind the next brake off.
Therefore, the Spring power fan that the utility model provides is simple in structure, modern design, and it does not need electric energy, but adopt the energy of clockwork spring as fan, not only power saving, safe and reliable, not can use by the restriction of power supply whenever and wherever possible, place for power failure or electricity consumption inconvenience, and the place of electricity consumption The limited time system, bring great convenience to the user, to satisfy people's needs.
Describe in detail below in conjunction with embodiment's accompanying drawing.
At first accompanying drawing is described:
Fig. 1 represents rear view of the present utility model;
Fig. 2 represents plan structure schematic representation of the present utility model,
The A-A sectional view of Fig. 3 presentation graphs 2.
Referring to accompanying drawing, the utility model is made up of flabellum, power, ratchet mechanism and gear, and wherein flabellum 7 is contained on the fan shaft 6, at an end of fan shaft 6 knob 9 is housed also.Ratchet mechanism 4 is housed on line shaft 3, ratchet mechanism 4 connects with fan shaft 6 by gear 5 again, gear 5 is a gear shift, clockwork spring 2 is housed on line shaft 3, one end of line shaft 3 is equipped with handle 1, the adjustable structure that bar and overcoat constituted in handle 1 was served as reasons, and turning joint 12 is housed, stop cap 8 is housed on the gear 5.
During use, by the turning joint on the handle 1 12 handle 1 is stretched, and then with handle 1 elongation, handle with sleeve 1, drive line shaft 3 rotations and make clockwork spring 2 accumulation of energys, because the effect of ratchet mechanism 4, line shaft 3 can only rotate along the direction that clockwork spring is screwed, and gear is motionless, when handle 1 turns to when almost changeing motionless, illustrate that clockwork spring 2 has been in the state of screwing, store enough energy, handle 1 should stop operating this moment, clockwork spring 2 releases energy, drive line shaft 3, make fan shaft 6 rotations by ratchet mechanism and gear shift 5, fan is started working.If want to allow fan quit work, press stop cap 8, gear shift 5 forces fan shaft 6 and forces line shaft 3 to stop operating by ratchet mechanism 4, when desiring to start once more, extracts stop cap 8 and gets final product.If can not start fan work after clockwork spring 2 discharges at once, can adopt assistant starting, promptly by knob 9 rotary fan axles 6.To start fan work.
Claims (5)
1, a kind of Spring power fan is made up of flabellum, power and gear, and flabellum is contained on the fan shaft, and fan shaft connects with line shaft by gear, it is characterized in that being equipped with on line shaft clockwork spring, and line shaft one end is equipped with handle.
2, Spring power fan according to claim 1 is characterized in that on the line shaft between line shaft and the gear ratchet mechanism being housed.
