Description
Technical field
The utility model relates to a kind of External memory equipment of computing machine, relates in particular to a kind of USB flash disk.
Background technology
The most crucial position of USB flash disk just is its movement, movement comprises a pcb board+master control+crystal oscillator+capacitance-resistance electric capacity+USB head+LED head+FLASH (flash memory) chip, what in use directly contact computer USB interface is pcb board, to use the most frequently contact site, be tending towards in prior art is hidden in mostly to the use of USB flash disk pcb board design, so often bring the inconvenience of use and can't promptly and accurately patch, existing USB flash disk also ubiquitous a kind of drawback is exactly content size and the remaining storage space that specifically deposits in can't be the clearly cognitive dish.
The utility model content
In view of this, be necessary to provide a kind of being convenient to patch on the USB interface of computer, and be convenient to the USB flash disk of clearly cognitive inner residue memory space.
The utility model is to realize like this, a kind of USB flash disk comprises disk body, pcb board, locking key, a LED lamp, No. two LED lamps, No. three LED lamps, No. four LED lamps, the upper dignity at the two ends of described disk body respectively is provided with described pcb board, described pcb board expansion body extension is to the lower dignity at the two ends of described disk body, and described pcb board adopts embedded mode to be embedded in the described disk body in the end at the two ends of described disk body, a described LED lamp, described No. two LED lamps, described No. three LED lamps, described No. four LED lamps are installed on the described disk body, and be connected with the memory device of described USB flash disk inside, described locking key is arranged on the side of described disk body.
Further, described body structure is symmetrical up and down.
Further, a described LED lamp, described No. two LED lamps, described No. three LED lamps, described No. four LED lamps all are connected with described pcb board.
The advantage of the USB flash disk that the utility model provides is: the two ends of the utility model USB flash disk up and down dignity all are provided with pcb board, be convenient to patch on the USB interface of computer housing, reduce the unnecessary damage to USB flash disk that patches the mistake in the process and cause, the serviceable life of strengthening USB flash disk.
By a LED lamp, No. two LED lamps, No. three LED lamps, No. four LED lamps are set at disk body, cut all and be connected with the memory device of disk body inside, be convenient to observe the storage inside state, represent when No. one the LED lamp is bright that memory space is that 25%, No. two LED lamp represents that memory space is that 50%, No. three LED lamp represents that memory space is that 75%, No. four LED lamp represents that memory space is 100% when bright when bright when bright.
By in the disk body side locking key being set, without USB flash disk the time, locking key is closed, effectively the safety of the internal file of protection.
Description of drawings
Fig. 1 is the vertical view of the utility model USB flash disk.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the side view of Fig. 2.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 2 and Fig. 3, wherein Fig. 1 is the vertical view of the utility model USB flash disk 100, and Fig. 2 is the side view of Fig. 1, and Fig. 3 is the side view of Fig. 2.
Described USB flash disk 100 comprises disk body 10, pcb board 20, locking key 30, a LED lamp 1, No. two LED lamps 2, No. three LED lamps 3, No. four LED lamps 4, upper honorable 11 of the two ends of described disk body 10 respectively are provided with described pcb board 20, described pcb board 20 expansion body extensions are to lower honorable 12 of the two ends of described disk body 10, and described pcb board 20 adopts embedded mode to be embedded in the described disk body 10 in the end at the two ends of described disk body 10, a described LED lamp 1, described No. two LED lamps 2, described No. three LED lamps 3, described No. four LED lamps 4 are installed on the described disk body 10, and be connected with the memory device of described USB flash disk 100 inside, described locking key 30 is arranged on the side of described disk body 10.
