Abstract
The utility model relates to a manual power generation charging device, in particular to an automatic hand-pulled power generation device. The automatic hand-pulled power generation device comprises a base plate (1), a power generator (2) and a hand-pulled driving force generation device (3) fixed on the base plate (1); the power transmission between the hand-pulled driving force generation device (3) and the power generator (2) is performed through a transmission device (4); the hand-pulled driving force generation device (3) comprises a return box (31); a mandrel (32) and a deboost spring (33) for restoring force are arranged in the return box (31); the mandrel (32) of the deboost spring is provided with a clamping groove structure (34); and the spring (33) is fixed in the clamping slot structure (34) on the mandrel (32). Through the improvement of the hand-pulled power generation device that the mandrel and a shaft sleeve are designed as a whole body, and a slot is formed on the mandrel for fixing the spring used for wire return, so as to greatly improve the production efficiency in the production process; and the return box and an iron plate are separately processed and are riveted combined, thereby considerably improving the production efficiency and greatly reducing the fraction defective.
Description
Technical field
The utility model relates to a kind of charging unit of manual generating, especially a kind of hand-pulling type self-generating device.
Background technique
At present,, a kind of electricity generating device of hand-pulling type is arranged on the market, but thereby battery is charged by pulling self power generation in order under no civil power situation, battery to be charged.
The patent No. be ZL200720058124.0 patent disclosure a kind of hand-pulling type electricity generating device, wherein, transmission device central shaft and axle sleeve two-part for separating, in the as installed process, need to assemble, substrate is one with time power box, owing to want punching press and stretch to finish synchronously and could realize, in the process of specific implementation great difficulty is arranged in process of production, cost of production and reject ratio are all very high.
Summary of the invention
One of the purpose of this utility model provides a kind of manufacturing efficiency height, the hand-pulling type electricity generating device that reject ratio is low.
To achieve these goals, the utility model adopts following technological scheme:
It comprises substrate (1) and is fixed on the generator (2) on the substrate (1) and pulls power generating apparatus (3), pull between power generating apparatus (3) and the generator (2) by transmission device (4) power transmission, comprise a power box (31) pulling power generating apparatus (3), be provided with an axle (32) in the described time power box (31) and be used for the clockwork spring (33) of Hui Li, its improvement is: the described axle of clockwork spring (32) is provided with a draw-in groove structure (34), and described clockwork spring (33) is fixed in the draw-in groove structure (34) on the axle (32).
In the said structure, riveted is fixed between described time power box (31) and the substrate (1).
Hand-pulling type electricity generating device of the present utility model advanced to improve axle and axle sleeve was designed to one, fixing clockwork spring of using of loop line of fluting on this, effect has bigger change than before improving, improved manufacturing efficiency in process of production greatly, now return power box and iron plate separate machined, two-part riveted joint combination, manufacturing efficiency increases substantially like this, and reject ratio descends greatly.
Description of drawings
Fig. 1 is the utility model hand-pulling type electricity generating device embodiment's a perspective view;
Fig. 2 is the utility model hand-pulling type electricity generating device embodiment's an internal mandrel structural representation;
Fig. 3 is the utility model hand-pulling type electricity generating device embodiment's a side structure schematic representation.
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As depicted in figs. 1 and 2, it comprises embodiment of the present utility model substrate 1 and is fixed on the generator 2 on the substrate 1 and pulls power generating apparatus 3, pull between power generating apparatus 3 and the generator 2 by transmission device 4 power transmission, comprise power box 31 one time pulling power generating apparatus 3, return between power box 31 and the substrate 1 and formed a containing space, this containing space is used for placement and pulls power generating apparatus, be provided with an axle 32 and the clockwork spring 33 that is used for Hui Li in the described time power box 31, the described axle 32 of clockwork spring is provided with a draw-in groove structure 34, and described clockwork spring 33 is fixed in the draw-in groove structure 34 on the axle 32.
As shown in Figure 2, in order to be that the processing of part is easier, to return between power box 31 and the substrate 1 riveted described in the present embodiment and fix.From but return power box 31 and substrate 1 can separate machined, improved manufacturing efficiency.
Advanced to improve axle and axle sleeve were designed to one, fixing clockwork spring of using of loop line of fluting on this, transmission device central shaft and axle sleeve two-part have in the past been solved for separating, in the as installed process, need the problem of assembling, effect had bigger change before improving, improved manufacturing efficiency in process of production greatly.To return power box and iron plate separate machined in addition, two-part riveted joint combination, solved original substrate and be one with time power box, in process of production owing to want punching press and stretch to finish synchronously and could realize, in the process of specific implementation, great difficulty is arranged, the drawback that cost of production and reject ratio are all very high, thus manufacturing efficiency is increased substantially, and reject ratio descends greatly.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (2)
