Description

The concertina type USB flash disk

Technical field

The utility model relates to the USB flash disk that uses on a kind of computer, and particularly a kind of over cap, USB flash disk main body, shell connect together, and only needs can open by a simple motion USB flash disk of over cap.

Background technology

Various ways is stamped in the protection of existing USB flash disk; what generally adopt is over cap and each self-separation of shell; in use; pull out the USB interface of over cap insertion computer; cause over cap to lose easily like this; thereby cause dust or rubbish to enter the USB flash disk socket, cause damage, even might make the loss of data of depositing in the USB flash disk.

Summary of the invention

The purpose of this utility model provides a kind of concertina type USB flash disk, and shell, main body, the over cap of USB flash disk connected together, and prevents to lose when the user from using over cap.

The scheme that its technical problem that solves the utility model adopts is: USB flash disk is made up of shell, main body, over cap three parts.Two sliding trays are left at the back side of shell, and one of them is shaped as straight line, and another is three sections broken line shapes; Can slide smoothly after making the USB flash disk main body put into the USB flash disk shell, shell left surface the first half also leaves a rectilinear sliding tray.One column salient point is arranged on the one side of over cap, be used for connecting shell, promptly put into the sliding tray of broken line shape on the shell back side; In the lower right of its column salient point a circular hole is arranged, be used for connecting main part, promptly be enclosed within on the column salient point of USB flash disk main body, and then the column salient point that will package circular hole is put into rectilinear sliding tray on the shell back side.Side in the USB flash disk main body is provided with a semicircular salient point that the user can be promoted, put it in the rectilinear sliding tray of shell side, when promoting this semicircle salient point, the USB flash disk main body moves vertically upward along rectilinear sliding tray, and this moment, the circular hole of over cap also moved vertically upward along sliding tray; The sliding tray of broken line shape makes the column salient point on the over cap move as camber line obliquely, thereby drives the whole protecting lid to left avertence, finally makes over cap slide to a side of USB flash disk main body.For over cap can be opened fully, linear sliding tray and broken line shape sliding tray equal in length, and the top is in same horizontal plane; In order to prevent the USB flash disk main body when opening or closing, not slip that can be random, the two ends of broken line shape sliding tray are respectively level and linear.

The beneficial effects of the utility model are: over cap simple in structure, easy to use, as can not lose USB flash disk can play a very good protection to the USB flash disk socket.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1, referring to accompanying drawing 1, in the one side of USB flash disk over cap a column salient point (1) is housed, and there is a circular hole (2) its lower right; One side of USB flash disk over cap is an opening, can not stop it to continue to move up in the USB flash disk main body moves up process with the side of guaranteeing over cap; Less than the top of sliding tray (5) distance to cover top portion, when guaranteeing that the USB flash disk over cap is opened fully, its outside is lower than the USB flash disk shell to circular hole (2) to the distance on USB flash disk over cap right side.

Embodiment 2, referring to accompanying drawing 2, the one side of USB flash disk main body is provided with a column salient point (3), its distance to USB flash disk main body top equates with the distance of circular hole (2) to USB flash disk over cap top, column salient point (3) equates with the distance of circular hole (2) to USB flash disk over cap right side to the distance on USB flash disk main body right side, to guarantee that circular hole (2) is enclosed within on the column salient point (3), makes over cap contact fully with the USB flash disk main body; One side of USB flash disk main body is equipped with semicircular salient point (4); it is to the distance at USB flash disk main body top; should greater than sliding tray (5) bottom to the distance of cover top portion and circular hole (2) to the over cap left side apart from sum; when semicircle salient point (4) when being pushed to the top; guarantee that the USB flash disk over cap can be opened fully; slide to a side of USB flash disk main body simultaneously, and become the obtuse angle, the USB plug of USB flash disk and the USB interface of computer are engaged fully with the USB flash disk main body.

Embodiment 3, referring to accompanying drawing 3, sliding tray (5) and sliding tray (6) arranged on the shell back side, and sliding tray (5) is a linear, and sliding tray (6) is three sections broken line shapes, both equal in length, and length is slightly larger than the length of USB flash disk USB plug; The top of the top of sliding tray (5) and sliding tray (6) is on the same horizontal plane, to guarantee that the USB plug of USB flash disk is in above the USB flash disk shell fully when over cap is opened fully; Sliding tray (5) bottom equals the distance of circular hole (2) to USB flash disk over cap top to the distance of cover top portion; The level interval of sliding tray (5) bottom bottom sliding tray (6) equals the level interval of column salient point (1) and circular hole (2); Sliding tray (5) bottom equates with the vertical interval of circular hole (2) with the vertical interval and the column salient point (1) of sliding tray (6) bottom; with guarantee the USB flash disk over cap, that main body is connected with shell is suitable; and when column salient point (1) and (3) were in two sliding trays bottoms, the USB flash disk over cap can be closed fully.Put into the USB flash disk shell for assurance USB flash disk main body, can slide smoothly, shell left side the first half leaves a rectilinear sliding tray (7), and its bottom is a little less than the bottom of sliding tray (5).
