Abstract
The utility model relates to a kind of Manual fan, comprise in order to hand-held supporting frame, support frame as described above is equipped with transmission shaft along support frame as described above length direction, described transmission shaft is fixedly connected with impeller through after supporting frame, described transmission shaft is arranged with at least one in order to drive the first bevel gear of drive axis, support frame as described above one side warp beam is held supporting base, bearing and link and is connected with the second bevel gear, and described first bevel gear and the second bevel gear engage each other formative gear pair.The utility model structural design is simple, and use efficient and convenient, the utility model is applicable to the construction site such as mine, bomb shelter, particularly when power supply system is broken, second bevel gear drives the first bevel gear to rotate, thus drives transmission shaft, wheel rotation, plays and goes out wind action fast.
Description
Technical field
The utility model relates to a kind of Manual fan.
Background technique
Blower fan is that the custom of China to gas compression and gas conveying machinery is called for short, and usually said blower fan comprises ventilator, blower, wind-driven generator etc.Existing blower fan main structural components is impeller, support, motor, belt pulley, joint control, driving component etc., main dependence motor provides mechanical energy, and mechanical energy is converted to gas pressure energy and kinetic energy, but in the field that construction environment is severe, the particularly construction site such as mine, bomb shelter, once motor breaks down or power supply system goes wrong, during repairing, blower fan cannot work, and delays construction.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, Manual fan convenient to use.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of Manual fan, comprise in order to hand-held supporting frame, support frame as described above is equipped with transmission shaft along support frame as described above length direction, described transmission shaft is fixedly connected with impeller through after supporting frame, described transmission shaft is arranged with at least one in order to drive the first bevel gear of drive axis, support frame as described above one side warp beam is held supporting base, bearing and link and is connected with the second bevel gear, and described first bevel gear and the second bevel gear engage each other formative gear pair.
Further, support frame as described above is provided with fixing rod in the bilateral symmetry of transmission shaft, and two fixing rods are fixedly connected with bearing support block.
Further, on described transmission shaft, spacer sleeve is provided with two the first bevel gears, and two the first bevel gears are meshed with the top of the second bevel gear, bottom respectively.
Further, described impeller comprises the arc shaped blade that some annular space are arranged.
Further, described second bevel gear is provided with the handle rotating the second bevel gear.
Compared with prior art, the utility model has following beneficial effect: the utility model structural design is simple, use efficient and convenient, the utility model is applicable to the construction site such as mine, bomb shelter, particularly when power supply system is broken, second bevel gear drives the first bevel gear to rotate, thus drives transmission shaft, wheel rotation, plays and goes out wind action fast.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
