Description

A kind of telescopic USB flash disk

Technical field

The utility model relates to storing apparatus, is specifically related to a kind of telescopic USB flash disk.

Background technology

In the prior art; mobile USB flash disk is little with its volume, and storage capability is big, movably advantage; be extensive use of in the IT industry; existing mobile USB flash disk structure all is that the dish core is fixed in the housing usually, and the plug of dish core exposes, when not using; over cap is set in the end of housing comes protective disc core plug; there is following defective in the mobile USB flash disk of this structure: over cap and housing are released states, use inconvenience, and over cap is lost easily.

The utility model content

The purpose of this utility model is, a kind of telescopic USB flash disk is provided, and this telescopic USB flash disk does not need the independent protection lid can realize coiling the reliably protecting of core plug yet, and is easy to use.

The technical scheme that the utility model provides is as follows: construct a kind of telescopic USB flash disk, comprise housing, be arranged on the dish core in the described housing, described dish core can skid off or slide into from described housing, be provided with the opening that the inserted terminal for described dish core stretches out at the front end of described housing, the adjacent position of described dish core and described housing is provided with the control device of the described dish core slip of control.

In above-mentioned telescopic USB flash disk, described control device is to be provided with internal thread in the second half section of described inner walls, is provided with the external thread that is meshed with described internal thread in the second half section of described dish core, is provided with knob on the breech face of described dish core.

The utlity model has following advantage: the dish core in the telescopic USB flash disk adopts the flexible structure that skids off to be connected with housing; only need during use dish core is skidded off from housing and can use, after using, will coil core and take in that housing is interior to get final product; do not need to put again the independent protection lid, easy to use.
