Abstract
The utility model discloses a flash memory, which comprises a casing, a PCB (printed board circuit) body and an interface, wherein the PCB (printed circuit board) body is connected with the interface, a pluggable device is arranged at the tail end of the casing, the pluggable device comprises a round hole, and the diameter of the round hole is 15 mm to 25 mm. With the combination of the flash memory and the pluggable device, the problem that the flash memory of the prior art is inconvenient for the aged, the children and the disabled with hand defect to plug and pull out is solved, and the flash memory of the utility model can be plugged and pulled out by a single finger, thereby being greatly convenient for the aged, the children and the disabled with hand defect.
Description
Technical field
The utility model relates to a kind of flash memories, relates in particular to the flash memories that a kind of the old and the children of being convenient to use.
Background technology
Flash memories is as a kind of medium of convenient and swift storage data, and is very popular on market at present.Its core structure is consistent basically, all is that PCB body and interface are fixedly connected in the enclosure.Shell generally all adopts the plastics material, adopts a lid to cover interface in order to protect interface simultaneously.But the handicapped personage of the old and the children and hand in use plugs very inconvenience.Existing Chinese patent notification number CN201499401U on June 2 2010 day for announcing, has announced a kind of anti-lost USB flash disk cap.It is to connect and prevent losing of USB flash disk lid a flexible cord is set between USB flash disk shell and USB flash disk lid.Chinese patent notification number CN201557337U on August 18 2010 day for announcing, has announced a kind of dual-purpose USB flash disk.It is that tail end at USB flash disk is provided with a rubber, to increase the function of USB flash disk.More than two kinds of utility models all do not solve the problem of plug inconvenience in the flash memories.
Summary of the invention
The purpose of this utility model is to provide a kind of flash memories easy to use, solves present the old and the children and the handicapped personage of hand and is using all very inconvenient problem of plug in the flash memories.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of flash memories comprises shell, PCB body and interface, and described PCB body is connected with interface, it is characterized in that, the tail end of shell is provided with plug-in and pull-off device, and described plug-in and pull-off device comprises circular hole, and the diameter of circular hole is 15mm-25mm.By the setting of circular hole on the rear-mounted installation, the user can insert a finger in the circular hole, just can plug flash memories easily then.
As preferably, described shell tail end is provided with the slot that is parallel to the interface cross section, and plug-in and pull-off device is provided with and the suitable cutting of described slot, and plug-in and pull-off device is connected with shell by transplanting a cutting.There is the personage who needs to load onto plug-in and pull-off device for the old and the children and the handicapped personage of hand etc., can selects to load onto or unload plug-in and pull-off device for unwanted personage.
As preferably, described PCB body dual-side is provided with the interface slide key, and the shell dual-side is provided with two tracks, and the slide key setting in orbit.PCB body and interface can be free to slide at track, when needing to use, PCB body and interface can be released, and when not required, can return PCB body and interface.Avoid the structure of flash memory lid, thereby avoided the generation of flash memory losing of cover.
As preferably, described slot is a dovetail groove, and the cross section of described cutting is a trapezium structure, transplants a cutting with slot suitable.Dovetail groove makes shell and plug-in and pull-off device bonding strength bigger.
As preferably, described plug-in and pull-off device is that the bottom surface is the column of U-shaped, and the curved portion of described U-shaped is a semicircle, and the center of circle of described circular hole overlaps with the center of circle of semicircle.Adopting the bottom surface is the column of U-shaped, makes whole flash memories more mellow and full, has saved the material of making simultaneously.
As preferably, the thickness of described plug-in and pull-off device is successively decreased to the tail end of plug-in and pull-off device by the tail end of shell.Under the constant prerequisite of intensity, adopt the thickness that successively decreases, saved manufactured materials, make profile more attractive in appearance simultaneously.
The beneficial effects of the utility model are: the flash memories that it has solved prior art in use plugs all the very problem of inconvenience for the old and the children and the handicapped personage of hand, the utility model can adopt single finger plug flash memories, greatly facilitates the handicapped personage of the old and the children and hand.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Among the figure: 1, shell, 2, PCB body and interface, 3, slide key, 4, plug-in and pull-off device, 5, circular hole, 6, cutting and slot.
Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described specifically:
In the embodiment shown in fig. 1, a kind of flash memories comprises shell 1, PCB body and interface 2, and described PCB body is connected with interface, and the tail end of shell 1 is provided with plug-in and pull-off device 4, and described plug-in and pull-off device comprises circular hole 5, and the diameter of circular hole is 20mm.The cross section that described plug-in and pull-off device is provided with is that trapezium structure is transplanted a cutting, and the interface cross section that is parallel to of shell tail end is provided with and the corresponding slot of slot.Plug-in and pull-off device is connected with slot 6 by transplanting a cutting with shell.Plug-in and pull-off device is that the bottom surface is the column of U-shaped, and its thickness is successively decreased to the tail end of plug-in and pull-off device by the tail end of shell.
During use, the user can insert a finger in the circular hole, just can plug flash memories easily then.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
