Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is a main TV structure schematic diagram of the present utility model;

Fig. 2 is that master of the present utility model looks cross-sectional view;

Fig. 3 is a backsight structural representation of the present utility model;

Fig. 4 is a perspective view of the present utility model.

The specific embodiment

The structure of the utility model hand charging tube is formed shell by engineering plastics ABS, and thickness of shell is not less than 2mm, meet national small domestic appliance second standard, and shock resistance is good, and is indeformable.Inside is equipped with swing type hand pressure lever 3, this purpose mainly is in order to realize manual push type lever, meet ergonomic designs, the comfort level of palm, can the maximum stroke of realizing hand, and after the continuous operation many hours, finger does not have aches, and arm does not have the effort sensation, considers the electrically fast and impulsive force of manual compression, so structure has reinforcement, inside is fixed with simultaneously and drags gear 4, drags gear bar profile such as chain form, when pushing work, the swing type hand pressure lever drives simultaneously and drags the gear bar, drag the gear bar and in fixing circumference, become to move back and forth, when past action presses down, utilize the reset function of spring, palm is loosening, and the swing type hand pressure lever resets.

Double-deck gear wheel, with double-deck gear, cog 5 and lower gear 6, the function of operating principle is when dragging the work of gear bar, drive lower gear simultaneously, the number of teeth of lower gear is 10 teeth, just when the depressing fast of palm, about about circumference 300 degree of pinion quick rotation, people's manual compression rotating speed is about 25rm/min, by dragging the lower gear that is transferred to double-layer gear of gear bar, rotating speed is 250rm/min just, owing to adopted double-layer gear, double-layer gear is also with regard to corresponding rotation simultaneously, and this belongs to the connection lever, the number that cogs of double-layer gear is 80 teeth, just when center of circle of double-layer gear rotation was all, the gear that cogs was under the situation of same reference, and the number of teeth has changed the variation of 250X80 tooth.Double-layer gear is owing to taken on the intermediate link effect, so the engineering plastics POM of the wear-resisting anti-action of material selection, with the general material of existing small domestic appliance, and the centre adds the balance pipe position, deducts the unnecessary off-centre that rotation drove simultaneously and vibrates.

It on the rotating shaft commutator 8 miniature gear, gear is in respect of 12 teeth, press the rotating speed of gear wheel, pinion rotating speed 1600 changes, running up like this is enough to allow 8 magnetic pole dc generators send very strong electric weight, in fact because the merit consumption of centrifugal swing bar, also reduce many energy, but it is still very strong to drive dc generator, the rotating shaft commutator mainly still is an intermediate, be a rotating lever that drives transmission because under the situation of high speed rotating, centrifugal swing bar 7 be one can a fixing spill spin block, under the high speed rotating speed, produce stronger centrifugal action, the inertia that drives simultaneously on the eight magnetic pole direct current generators 9 increases the weight of flywheel 10, and inertia increases the weight of flywheel inside and adopted contrary rotation tooth-like.

Inertia increases the weight of flywheel accepted the strength of centrifugal swing bar after, running simultaneously, owing to be to run up, after manual mode stops, the rotating shaft commutator shuts down simultaneously, be added with lubricated oil condition in the middle of utilizing, the centrifugal swing bar breaks away from the rotating shaft commutator, inertia increases the weight of flywheel and continues rotation at a gallop, eight magnetic pole generators have obtained the effect of cutting magnetic line, according to right-hand law, the magnet steel magnetic pole of eight magnetic pole generator magnetic poles and stator sends direct current, uses for outside, because be hand, resetting of spring can allow the centrifugal swing bar break away from the contrary rotary teeth that inertia increases the weight of flywheel quickly, realized the reciprocal motion that goes round and begins again like this, and inertia increases the weight of flywheel simultaneously always all in running, have only when external strength stops, be palm when not compressing, inertia increases the weight of flywheel and is still keeping the inertia rotation, is supporting the generated energy of dc generator simultaneously.

A parts switch lock is arranged to switch 11 in lower part of frame; be to be used for blocking resetting of swing type hand pressure lever; main purpose is for swing type hand lever is limited in the housing like this, is used at ordinary times not time spent safeguard measure, prevents that dust and other foreign matters from entering enclosure interior.

The electric weight of eight magnetic pole dc generators output through commutation diode, is delivered directly on the rechargeable battery 12, also be parallel on the lamp holder serial component 13 simultaneously, with the luminous lighting diode, fluorescent tube has had the voltage and the function of current in the lamp holder serial component, begin luminously, realize the function of illumination.

At the rechargeable battery output, a switch 14 is arranged, mainly be power switch, mainly be when not needing when manual, still can export electric weight and make for light emitting diode and be used for illumination.

Out-put supply interface 15 is an independent equipment, is an electronic diode output equipment by anti-reverse short circuit, is mainly used to the interface to miniature toy and the power supply of communication mini-plant.
