Abstract
The utility model discloses a portable fan which comprises a shell body. A driving gear and a driven gear are meshed with each other and mounted in the shell body. A gear shaft of the driving gear is fixedly connected on a clockwork mechanism on the inner wall of the shell body. A pull rope is further twined on the gear shaft of the driving gear. The pull rope stretches out of the shell body. One end of a gear shaft of the driven gear is rotatably and fixedly connected on a shaft seat on the inner wall of the shell body, and the other end of the gear shaft of the driven gear stretches out of the shell body and is connected with a fan blade mounting seat. Fan blades are fixed on the fan blade mounting seat. According to the portable fan, the pull rope is utilized to pull the gear shaft of the driving gear to rotate, thereby achieving exertion of force on the clockwork mechanism connected with the gear shaft of the driving gear. When the pull rope is loosened, the fan blades can be driven to rotate by means of elastic force released by the clockwork mechanism, and coordination between the driving gear and the driven gear. Therefore, the portable fan is simple in structure, convenient to use, and capable of being carried about.
Description
Technical field
The utility model relates to a kind of Portable fan.
Background technique
Existing fan mostly is greatly motoring formula fan, need energising during use, the use position of fan is subject to the restriction of electrical socket and wire, and the flexibility of its using scope and position adjustment is subject to larger restriction, and existing fan volume is generally larger, is not easy to carry.
Summary of the invention
Technical problem to be solved in the utility model provides Portable fan a kind of easy to carry, simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: Portable fan, comprise housing, driving gear and the driven gear of engagement are installed in the described housing, the gear shaft of described driving gear is fastened on the clockwork on the described inner walls, also be wound with stay cord on the gear shaft of described driving gear, described stay cord stretches out described housing; Gear shaft one end of described driven gear is rotationally connected the axle bed that is fixed on the described inner walls, and the gear shaft the other end of described driven gear stretches out described housing and is connected with the fan blade fitting seat, is fixed with fan blade on the described fan blade fitting seat.
As preferred technological scheme, described clockwork comprises the Reed type clockwork spring and for the clockwork axis that twines described clockwork spring, described clockwork axis one end rotates and is installed in the described housing, and the described clockwork axis the other end connects the gear shaft of described driving gear.
As to improvement of the technical scheme, described stay cord end is provided with and prevents that stay cord from entering the limiting stopper in the described housing.
Owing to adopted technique scheme, Portable fan, comprise housing, driving gear and the driven gear of engagement are installed in the described housing, the gear shaft of described driving gear is fastened on the clockwork on the described inner walls, also be wound with stay cord on the gear shaft of described driving gear, described stay cord stretches out described housing; Gear shaft one end of described driven gear is rotationally connected the axle bed that is fixed on the described inner walls, and the gear shaft the other end of described driven gear stretches out described housing and is connected with the fan blade fitting seat, is fixed with fan blade on the described fan blade fitting seat; The beneficial effects of the utility model are: utilize the gear shaft of stay cord pulling driving gear to rotate, thereby realize to the clockwork that is connected with the gear shaft of driving gear energetically, unclamp stay cord, elastic force by clockwork release, and the cooperation by driving gear and driven gear, drive fan blade and rotate, simple in structure, easy to use, can carry.
Description of drawings
Accompanying drawing is the utility model embodiment's structural representation;
Among the figure: the 1-housing; The 2-driving gear; The 3-driven gear; The 4-clockwork spring; The 5-clockwork axis; The 6-stay cord; The 7-limiting stopper; The 8-axle bed; 9-fan blade fitting seat; The 10-fan blade.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
As shown in drawings, Portable fan, comprise housing 1, driving gear 2 and the driven gear 3 of engagement are installed in the described housing 1, the gear shaft of described driving gear 2 is fastened on the clockwork on described housing 1 inwall, clockwork described in the present embodiment comprises Reed type clockwork spring 4 and for the clockwork axis 5 that twines described clockwork spring 4, described clockwork axis 5 one ends rotate and are installed in the described housing 1, and described clockwork axis 5 the other ends connect the gear shaft of described driving gear 2.Clockwork can arrange many groups, is provided with three groups in the present embodiment, to satisfy user's needs.
Also be wound with stay cord 6 on the gear shaft of described driving gear 2, described stay cord 6 stretches out described housing 1, and when fan did not use, stay cord 6 was to be wrapped on the gear shaft of driving gear 2, and clockwork is in releasing state simultaneously; Pull out stay cord 6, the gear shaft that stay cord 6 can drive driving gear 2 rotates, and gives clockwork energetically simultaneously, unclamps stay cord 6, and clockwork discharges, and drives simultaneously driving gear 2 backward rotation.Prevent that for making things convenient for use can arrange in described stay cord 6 ends one stay cord 6 from entering the limiting stopper 7 in the described housing 1.
Gear shaft one end of driven gear described in the present embodiment 3 is rotationally connected the axle bed 8 that is fixed on described housing 1 inwall, the gear shaft the other end of described driven gear 3 stretches out described housing 1 and is connected with fan blade fitting seat 9, be fixed with fan blade 10 on the described fan blade fitting seat 9, when driving gear 2 rotates, drive driven gear 3 rotations with driving gear 2 engagements, thereby fan blade fitting seat 9 and fan blade 10 are rotated, and then produce wind.
The utility model makes fan break away from dependence to electric power, helps the flexible adjustment of position of fan, and small volume is convenient to carry simultaneously.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
