Description
[technical field]
The utility model relates to a kind of portable power source, particularly a kind of device to the digital electronic goods charging.
[background technology]
Along with the fast development of electronic product, the electronic product of carrying is also more and more, such as mobile phone, panel computer etc.For electric energy being provided for the electronic product of carrying whenever and wherever possible, industry has designed the portable power source with energy storage function, charges for the electronic products such as mobile phone, panel computer whenever and wherever possible.Existing portable power source all is to carry out with connecting wire connection external charger by the USB interface of being located on the portable power source when accumulate charges.Usually, circuit board and power circuit are to be fixed on the housing with screw or buckle mode, and this complex structure is loosening easily.
[utility model content]
The purpose of this utility model is the deficiency that overcomes above-mentioned portable power source, provides a kind of simple in structure, tight portable power source.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of portable power source is provided, comprises housing, circuit board and power circuit, it is characterized in that: described housing is cylinder, and the outer rim of cylinder end is provided with screw thread; Also has a circular contiguous block, the diameter of circular contiguous block equates with the internal diameter of cylinder, circular contiguous block has a column type projection, circular contiguous block is inserted in the cylinder, the column type projection stops circular contiguous block against cylinder, circuit board is connected with circular contiguous block buckle with power circuit, and a gland with internal thread screws in cylinder end, and circular contiguous block is compressed.
Further improvement in the technical proposal is: described circuit board has two breach, and circular contiguous block stretches out two shell fragments with barb downwards, and the barb of shell fragment snaps in respectively two breach of circuit board.
Further improvement in the technical proposal is: described shell fragment is respectively arranged with stopper slot at root, and circuit board inserts in the stopper slot with fixing circuit board.
Further improvement in the technical proposal is: the end face of described circular contiguous block has the through hole of button installation switch, one end of push-button switch stretches out from through hole, the other end is corresponding to board switch, a junction is stretched out in the push-button switch side, there is a location hole end of connecting portion, the end face of circular contiguous block inwardly stretches out a reference column, and reference column is inserted in the location hole.
Further improvement in the technical proposal is: the end face of circular contiguous block has USB interface and charging inlet.
Further improvement in the technical proposal is: the other end of cylinder type shell is equipped with the LED lamp that is connected with power circuit.
The beneficial effects of the utility model are: the diameter of the circular contiguous block of the utility model equates with the internal diameter of cylinder, circular contiguous block has a column type projection, circular contiguous block is inserted in the cylinder, the column type projection stops circular contiguous block against cylinder, circuit board is connected with circular contiguous block buckle with power circuit, and a gland with internal thread screws in cylinder end, and circular contiguous block is compressed, thereby simple in structure, connect reliable.

[embodiment]
Shown in Fig. 1 to 9:
A kind of portable power source comprises housing, circuit board 1 and power circuit (not shown), and described housing is cylinder 2, and the outer rim of cylinder 2 ends is provided with screw thread; Also has a circular contiguous block 3, the diameter of circular contiguous block 3 equates with the internal diameter of cylinder 1, circular contiguous block 3 has a column type projection 4, circular contiguous block 3 is inserted in the cylinder 1, column type projection 4 stops circular contiguous block 3 against cylinder, like this, circular contiguous block 3 is placed in the cylinder 1 just, and because the barrier effect of column type projection 4 makes circular contiguous block 3 can not fall into cylinder 1 inside, circuit board is connected with circular contiguous block buckle with power circuit, one gland with internal thread screws in cylinder end, circular contiguous block is compressed (not shown gland is because this another technical staff of this screw connection structure formula knows).
Described circuit board has two breach 5, and circular contiguous block 3 stretches out two shell fragments 7 with barb 6 downwards, and the barb 6 of shell fragment 7 snaps in respectively two breach 5 of circuit board.
Described shell fragment is respectively arranged with stopper slot 8 at root, and circuit board inserts in the stopper slot 8 with fixing circuit board.
The end face of described circular contiguous block 3 has the through hole 10 of button installation switch 9, one end of push-button switch 9 stretches out from through hole 10, the other end is corresponding to board switch, a junction 11 is stretched out in push-button switch 9 sides, there is a location hole 12 end of connecting portion 11, the end face of circular contiguous block inwardly stretches out a reference column 13, and reference column 13 is inserted in the location hole 12.
The end face of circular contiguous block has usb 14 and charging inlet 15.
The other end of cylinder type shell is equipped with the LED lamp that is connected with power circuit.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
