Abstract

The utility model discloses a portable charger. The portable charger comprises a housing, and also comprises a slide block support, a spring framework, an adapter plate, a circuit board and a power plug which are coaxially arranged from top to down in the housing. When the portable charger is in use, an output plug arranged outside the housing is pulled until a power line reaches a preset length, the spring framework is rotated to make a spring store energy, and the spring is prevented from releasing forces and rebounding by the clamp effect of a ratchet wheel and a stop block. When the charger is idle or carried, users can press a button to make the clamp effect of the ratchet wheel and the stop block disappear, and wind the power line on the spring framework again by utilizing the elastic effect of the spring. Through the above process, the power line can be effectively prevented from being disarranged or the power line can be prevented from being wound with other articles, the using process is relatively convenient, and at the same time the charger of the above structure is provided with relatively good portability.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in more detail.

The utility model discloses a kind of portable charger, in conjunction with shown in Fig. 1 to Fig. 8, it includes a housing 1 and is located in housing 1 and the slider bracket 4 coaxially arranging from top to bottom, one clockwork spring skeleton 5, one keyset 6, one wiring board 7 and an attaching plug 10, within clockwork spring skeleton 5, be fixed with clockwork spring, slider bracket 4 is extended with the end clamping through the rotating shaft 40 of clockwork spring skeleton 5 and this rotating shaft 40 and clockwork spring downwards, the lower end of clockwork spring skeleton 5 is provided with brush, keyset 7 is provided with annular contact 70 and this annular contact 70 and brush butt, keyset 6 is fixed on wiring board 7 and the two electric connection, wiring board 7 is fixedly connected on attaching plug 10, on clockwork spring skeleton 5, be wound with power line 8, one end of this power line 8 and brush are electrically connected, its other end is electrically connected through housing 1 and with the output plug 9 being positioned at outside housing 1, the upper end of this clockwork spring skeleton 5 is provided with ratchet 50, slider bracket 4 is provided with a slide block 3 and this slide block 3 is connected with slider bracket 4 Elastic Sliding, the bottom of slide block 3 is provided with guide vane end stop 31 and this guide vane end stop 31 engages with ratchet 50, the top of housing 1 is provided with a button 2, the bottom of button 2 is provided with the first wedge shape part 20, slide block 3 is provided with the second wedge shape part 30, the inclined-plane of the inclined-plane of the first wedge shape part 20 and the second wedge shape part 30 offsets and the two is slidably connected.

The charger of said structure is when assembling, and power line 8 is wound on clockwork spring skeleton 5, and meanwhile, clockwork spring is in lax or low-potential energy state, and output plug 9 is stuck in outside housing 1.During use, pull output plug 9 until the power line 8 outside housing 1 reaches sufficient length, clockwork spring skeleton 5 rotates to make spiral power spring storaging energy, under the snap action of ratchet 50 and guide vane end stop 31, can prevent that the clockwork spring power of letting out from rebounding.While packing up power line 8 after charging finishes, press the button 2 at housing 1 top, due to the inclined-plane of the first wedge shape part 20 and the inclined-plane of the second wedge shape part 30 offsets and the two is slidably connected, so under the impetus of button 2, can drive slide block 2 outwards to slide, guide vane end stop 31 is separated with the gear teeth of ratchet 50, and the snap action of the two disappears, clockwork spring is let out power bounce-back and is driven clockwork spring skeleton 5 to rotate, until power line 8 is wrapped on clockwork spring skeleton 5 and output plug 9 is stuck in outside housing 1.

In order to realize slide block 3, be connected with the Elastic Sliding between slider bracket 4, slide block 3 is provided with a spring 32, and one end of spring 32 and slide block 3 offset, and its other end and slider bracket 4 offset.But this is only a preferred embodiment of the present utility model, be not limited to the utility model, in other embodiment of the present utility model, this spring 32 can also replace with other flexible member, thereby realizes the Elastic Sliding effect between slide block 3 and slider bracket 4.

About being electrically connected, because clockwork spring skeleton 5 needs reciprocating rotation, be difficult to directly with cable, power line 8 is connected with wiring board 7, so the utility model is realized electric connection by the keyset 7 and the brush that cooperatively interact, as a kind of optimal way, the quantity of brush is two, the quantity of annular contact 70 is two and the two concentric setting, two brushes respectively with two annular contact 70 butts, make power line 8 be electrically connected to wiring board 7, this wiring board 7 is processed the external voltage of attaching plug 10 inputs, export afterwards constant direct voltage and pass through successively annular contact 70, brush, power line 8 and output plug 9 and transfer to power consumption equipment.
