[embodiment]

Below in conjunction with accompanying drawing the embodiment embodiment is described in further detail.

Please refer to Fig. 3 and Fig. 4, a kind of portable USB flash disk comprises shell 10, sliding part 20 and fixture 30.Fixture 30 is connected in the shell 10, and sliding part 20 is slidingly mounted in the receiving space between shell 10 and the fixture 30.

Shell 10 is a die casting, is roughly the groove shape structure of a cuboid, comprises bottom surface 12 and the vertically extending sidewall 14 in three limits along the bottom surface.One end of shell 10 is provided with opening, be used for skidding off for sliding part 20, bottom surface 12 be provided with fixing hole 120 in the opposite centre position, an end end of opening.The wall 142 that sidewall 14 comprises vertical connection bottom surface 12 with vertically is connected wall 142 and with bottom surface 12 parallel and flanges 144 extension in shell 10.Form guide-track groove 140 between bottom surface 12, wall 142 and the flange 144.The relative end with openend of shell 10 is provided with lanyard hole 16 in addition, is convenient to hang USB flash disk with rope, to be convenient for carrying.

Fixture 30 is a working of plastics, also is roughly rectangular groove shape structure, matches with shell 10, forms a containing cavity jointly, to accommodate described sliding part 20.Fixture 30 both sides are provided with the guide rail 36 adaptive with guide-track groove 140, and guide rail comprises retainer 360, sliding part 362 and access portion 364.Access portion 364 is circular-arc, and its end height is convenient to guide rail 36 and is slipped into guide-track groove 140 less than the height of guide-track groove 140.Sliding part 360 height are highly the same with guide-track groove 140.Retainer 360 height are a little more than guide-track groove 140 height.Retainer 360, sliding

part

362 and 364 smooth connections of access portion.Being convenient to fixture 30 so further tightens with shell 10.

Fixture 30 bottoms are provided with square hole 32, and square hole 32 both sides respectively are provided with 34, one corresponding of two clamp bar slots and are arranged at square hole 32 heads, and another is located at square hole 32 afterbodys.Fixture 30 ends and corresponding position, described fixing hole 120 position are provided with projection 300, when fixture 30 when guide-track groove 140 slides in the shell 10, elastic deformation can take place in projection 300, when fixture 30 and shell 10 are seated, projection 300 springs back in the fixing hole 120, and fixture 30 is fixed in the described shell 10.

Sliding part 20 comprises body 22 and slide key 24, in one embodiment, body 20 can be one to be provided with the working of plastics of containing cavity, one end is provided with opening, USB flash disk storage element device is located in the described containing cavity, and USB interface is located in the described opening, slides by working of plastics, drive USB flash disk storage element device and skid off, so that use.

In another embodiment, body 22 also can be a USB flash disk storage element device itself.

Slide key 24 rectangular shapes can certainly be other shapes, as long as be convenient to slide.Slide key 24 1 ends and body 22 are affixed, and body 22 is provided with breach in slide key 24 fixed positions, and an end perk that makes slide key 24 be connected with body 22 is also unsettled.One end both sides of slide key 24 perks respectively are provided with a card ear 26, and body 22 corresponding card ears 26 positions also are provided with breach, make card ear 26 unsettled, are convenient to press downwards.Card ear 26 cooperates with described draw-in groove 34, can block body 22, because slide key 24 parts are unsettled, when needs use USB flash disk, pressing slide key 24 just can make card ear 26 break away from draw-in groove 34, when sliding part 20 skidded off the precalculated position, card ear 26 was upspring and is blocked draw-in groove 34, so just can prevent that sliding part from use sliding.

Please refer to Fig. 1 and Fig. 2, in the above-described USB flash disk, can omit sliding part 20, constitute a kind of fastening structure by shell 10 and fixture 30, the structure of same shell and fixture, shape also can be made change according to actual needs, as long as fixture is provided with projection, shell is provided with the fixing hole that cooperates with projection.By projection and cooperating of fixing hole realizing fastening effect, all fall into protection range of the present utility model.This fastening structure also can be applicable to other fields such as mobile phone, MP3.

This fastening structure, in the shell of packing into after the set column elastic deformation on the fixture, when being seated, column springs back to the fixing hole the inside, thereby realizes fasteningly, and this fastening structure is succinctly convenient, and assembling is efficient.Overcome in the past and to have realized technical problems such as the inconvenience of fastening effect and inefficacy easily by adhesions such as glue.

The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
