Technical problem to be solved in the utility model is：There is provided a kind of can preferably preserve filter membrane and prevent on filter membrane The powder sample storage box of dust releasing.

In order to solve the above technical problems, the technical solution adopted in the utility model is：Powder sample storage box, including upper end The rectangular box of opening, box opening end are provided with case lid, it is characterised in that powder sample storage is provided with the casing Layer, several V-shaped grooves are provided with the powder sample accumulation layer upper surface, two inclined-planes of V-groove press from both sides into 90 degree~120 degree Angle.

As a kind of preferable scheme, cushion, both ends are respectively arranged with two end faces that the V-shaped groove is parallel to each other Cushion on face offsets.

As a kind of preferable scheme, the cushion includes liner and outer cover, and the liner is flexible sponge, The outer cover is the smooth cotton in surface.

As a kind of preferable scheme, cushion is provided between the powder sample accumulation layer and casing inner bottom surface, should Cushion is by several elastic component matrix distributions on casing inner bottom surface.

As a kind of preferable scheme, the elastic component is sponge.

As a kind of preferable scheme, Damp-proof box is provided with the case lid inner top surface, is provided with the box body of Damp-proof box Multiple apertures.

As a kind of preferable scheme, the case lid is hinged on the side at box opening end, and box opening end is provided with close Strip of paper used for sealing, case lid lower surface is corresponding with sealing strip, and casing and case lid are tightly connected by sealing strip.

The beneficial effects of the utility model are：Filter membrane after doubling twice, formed knuckle for 90 degree or slightly larger than 90 degree, The bucket shape of upper end open, knuckle is downwardly into V-shaped groove, simple to operate, is taken conveniently, is kept filter membrane opening upwards, transporting Jolt or tilt even if being run into during defeated, also can effectively prevent dust from departing from filter membrane, so as to improve final accuracy of detection.

Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.

Powder sample storage box as depicted in figs. 1 and 2, includes the rectangular box 1 of upper end open, and the openend of casing 1 is set It is equipped with case lid 2, it is characterised in that powder sample accumulation layer 3, the upper end of powder sample accumulation layer 3 are provided with the casing 1 It is provided with several V-shaped grooves 4 on face, two inclined-planes of V-groove 4 are into 90 degree~120 degree angles.

Filter membrane 9 is wrapped up after doubling twice with clean A4 paper, is formed knuckle as 90 degree or is opened slightly larger than 90 degree, upper end The bucket shape of mouth, deposits in clean hermetic bag, then inserts knuckle downward communication seals bag in V-shaped groove 4 in the lump, operation letter It is single, take conveniently, keep bucket shape opening upwards, jolt or tilt even if being run into transportation, also can effectively prevent dust Depart from filter membrane 4, so as to improve final accuracy of detection.

It is respectively arranged with cushion 5 on two end faces that the V-shaped groove 4 is parallel to each other, the phase of cushion 5 in both ends of the surface Support, filter membrane 9 is inserted between two cushions 5, and cushion 5 plays clamping action to filter membrane 9, fixes filter membrane 9, prevents that filter membrane from being run Go out V-shaped groove 4.

The outer cover 5-2, the liner 5-1 that the cushion 5 includes liner 5-1 and is coated on outside liner 5-1 are with bullet Property sponge, the outer cover 5-2 is the smooth cotton in surface.

Sponge elasticity is moderate, and elasticity too conference makes in dust insertion filter membrane, and elasticity is too small not to have fixation, smooth cotton Cloth is easy to filter membrane to insert, and cotton moisture sorption effect is good, can prevent that filter membrane is moist.

Cushion 6 is provided between the powder sample accumulation layer 3 and the inner bottom surface of casing 1, the cushion 6 is by several bullets Property part 6-1 matrix distributions are on the inner bottom surface of casing 1.

Cushion 6 further improves stability of the filter membrane 9 in storage box.

The elastic component 6-1 is sponge, good buffer effect, and cost is low.

Damp-proof box 7 is provided with the inner top surface of case lid 2, multiple aperture 7-1 are provided with the box body of Damp-proof box 7, it is moistureproof Drier can be placed in box 7, keeps drying in storage box, prevents that powder sample is moist.

The case lid 2 is hinged on the side of the openend of casing 1, and the openend of casing 1 is provided with sealing strip 8, the lower surface of case lid 2 Corresponding with sealing strip 8, casing 1 and case lid 2 are tightly connected by sealing strip 8, are improved the sealing in storage box, are prevented air In aqueous vapor enter in cartonning.

Operation principle of the present utility model is：The secondary doubling of filter membrane that dust will be adsorbed with, make knuckle at 90 degree~120 degree Between, then knuckle is downwardly into V-shaped groove 4 between two cushions 5, filter membrane 9 is fixed, then covers case lid 2, Bian Kejin Row transfer, also will can first be put into hermetic bag memory storage after filter membrane doubling, filter membrane 9 then is inserted into V-shaped groove 4 together with hermetic bag It is interior.

When needing to take out filter membrane 9, as long as directly extracting, operation is very simple and convenient, while can be effective Prevent dust from departing from filter membrane in transportation, make final testing result more accurate.
