Thus the utility model can reduce dust excluding plate by setting idler wheel in the both sides of one end of dust excluding plate by idler wheel
Resistance in rotation process improves the flexibility of dust excluding plate rotation.
The phase prior art, the beneficial effects of the utility model are dust can be effectively prevent to enter USB jack, and structure letter
Single, flexibility is good, user-friendly.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to the structure shown in these attached drawings.
Fig. 1 is the structure diagram of dust-proof one embodiment of USB charger of the utility model；
Fig. 2 is the explosive view of Fig. 1；
The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.
Specific embodiment
The utility model proposes a kind of dust-proof USB chargers.
With reference to Fig. 1-2, the structure diagram of one embodiment of USB charger dust-proof for the utility model Fig. 1, Fig. 2 Fig. 1
Explosive view.
As shown in Figs. 1-2, in the utility model embodiment, which includes shell 100 and charging electricity
Road plate (not shown), charging circuit board are set in shell 100.Cover board 200 of the opening equipped with L-type of shell 100, cover board 200
Lateral part is equipped with USB jack 210, and shell 100 is equipped with the plug (not shown) being connect with power supply with respect to one end of its opening,
USB jack 210 is electrically connected with plug with charging circuit board.
The lateral part of cover board 200 is equipped with the dust excluding plate 300 for covering USB jack 210, the first end of dust excluding plate 300
Both sides be equipped with shaft, each shaft be equipped with idler wheel 310.The vertical section of cover board 200 is equipped with the first storage tank 220, houses
The both sides of slot, which are respectively equipped with, to be placed in two idler wheels, 310 corresponding sliding slot 230, idler wheel 310 in its corresponding sliding slot 230.
When not in use, dust excluding plate 300 is covered in USB jack 210.In use, dust excluding plate 300 is rotated up, when dust excluding plate 300
After 90 ° of Plane Rotation where USB jack 210, dust excluding plate 300 is equal with the sliding slot 230 of 220 both sides of the first storage tank
