Background technique:
At present, the technology about electric fan existing and that once had has been made very fruitful effort to energy-saving fan, also once designs many outstanding technological schemes.Such as being declared by Chen Lulu of the Decree of Patent Office of China in 2011, notice of authorization number is CN202056076U, China Patent No. (ZL) is: No. 201120155867.6 model utility, title are the utility model patents of " electric fan ", the technological scheme that adopts.At the technical elements of electric fan, be of great value innovation and creation, it has solved the technical problem that existing electric fan can't change height by the technological scheme that a height-adjustable expansion device is established in electric fan body bottom, still, also has many deficiencies:
It can't solve fan running needs electric power, the problem of waste electric energy.
Summary of the invention:
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, easy to use, need not the energy-saving fan of electricity consumption.
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises support and screw rod, it is characterized in that: the up and down two ends of screw rod are provided with positive stop key, be provided with the weight that cooperates with spiral on the spiral of screw rod, the weight side is provided with guide pad; Screw rod outer frame top is provided with guide sleeve, is provided with the guiding groove that matches with guide pad in the guide sleeve; Be provided with the drive sprocket that matches with the positive stop key of screw rod in the support; Drive sprocket links to each other with driven sprocket by chain, driven sprocket links to each other with the lower end of driving shaft, the top of driving shaft is stretched out support and is arranged in the fan guard, the upper end of driving shaft is provided with initiatively umbrella tooth, be provided with the driven umbrella tooth that matches with active umbrella tooth in the fan guard, driven umbrella tooth links to each other with fan blade.
As a kind of preferred version of the present utility model, described weight is 5kg.
The beneficial effects of the utility model:
1, simple in structure:
The up and down two ends of screw rod of the present utility model are provided with positive stop key, are provided with the weight that cooperates with spiral on the spiral of screw rod, and the weight side is provided with guide pad; Screw rod outer frame top is provided with guide sleeve, is provided with the guiding groove that matches with guide pad in the guide sleeve; Be provided with the drive sprocket that matches with the positive stop key of screw rod in the support: drive sprocket links to each other with driven sprocket by chain, driven sprocket links to each other with the lower end of driving shaft, the top of driving shaft is stretched out support and is arranged in the fan guard, the upper end of driving shaft is provided with initiatively umbrella tooth, be provided with the driven umbrella tooth that matches with active umbrella tooth in the fan guard, driven umbrella tooth links to each other with fan blade.Its member is few, and the utility model is simple in structure thus.
2, easy to use:
When the utility model uses, together be positioned over guide sleeve in together with weight screw rod, weight descends under Action of Gravity Field, drives screw rod and rotates, and screw rod drives drive sprocket by positive stop key and rotates, drive sprocket rotates by the chain-driving driven sprocket, driven sprocket drives driving shaft and rotates, and driving shaft drives initiatively umbrella tooth rotation, and initiatively the moving driven umbrella tooth of umbrella cingulum rotates, the moving fan blade of driven umbrella cingulum rotates, thereby realizes the function of fan.After weight falls within minimum point, screw rod of the present utility model can be taken out, reverses its direction is inserted in the drive sprocket again, weight again by peak to the whereabouts, repeatedly above-mentioned action, can keep always the blowing, operating method is simple, and is easy to use.
3, energy saving:
The utility model need not to use electric energy, reaches the purpose of energy saving.
