Abstract
The funnel stand of a kind of use for laboratory adjustment height and size, comprise support (1) and the middle empty pallet (2) equipped with support (1), described support (1) upper end is provided with screw thread, described middle empty pallet (2) is provided with lifting nut (5) with support (1) cooperation place, in the middle of described middle empty pallet (2), be fitted with movable bracket (3), described movable bracket (3) coordinates with the adjustment screw rod (4) being arranged on support (1); The utility model movable bracket is arranged to uniform trisection or the quartering, each decile is controlled by adjusting accordingly screw rod, so the centre bore of movable bracket can be realized for the size of funnel big or small freely adjusting, the funnel that can extensively be adapted to laboratory plurality of specifications model, has the features such as applied widely.
Description
Technical field
The utility model relates to a kind of simple rack of use for laboratory, more particularly, relates to the funnel stand of a kind of adjustment height and size.
Background technology
In conventional chemical analysis experiment; often can use funnel sample is carried out to filter operation; in general operation; all directly funnel to be inserted in to connect in liquid container to filter; the consequence brought of operation is thus: usually there will be the phenomenon that causes liquid receptacle ware to be toppled over because of crank class vessel such as (particularly) volumetric flasks, thereby affect experimental implementation.
Utility model content
The utility model, for prior art problem, discloses a kind of differing heights, different model specification funnel of being applicable to, the funnel stand of easy disassembly simultaneously.
Technique effect of the present utility model is intended realizing by following technology:
The funnel stand of a kind of use for laboratory adjustment height and size, comprise support (1) and the middle empty pallet (2) equipped with support (1), described support (1) upper end is provided with screw thread, described middle empty pallet (2) is provided with lifting nut (5) with support (1) cooperation place, it is characterized in that: in the middle of described middle empty pallet (2), be fitted with movable bracket (3), described movable bracket (3) coordinates with the adjustment screw rod (4) being arranged on support (1).
Adapt to for convenience the demand in place, described support (1) quantity can be set to 3-4 root, and described lifting nut (5) quantity is 3-4, and the quantity of support (1) is consistent with lifting nut (5) quantity.
For adapting to funnel and the container of plurality of specifications model, described movable bracket (3) is evenly divided into 3-4 group, and each group structure is identical, between group and group, is provided with gap, described adjustment screw rod (4) quantity is 3-4 root, and the group number of movable bracket (3) decile is consistent with adjustment screw rod (4) quantity.
Further, described gap length can be adjusted according to adjusting the propelling of screw rod (4) or release.
For increasing the stability of funnel stand, described support (1) lower end is provided with the lower margin (10) of indent, and described lower margin (10) outside is enclosed with corrosion-resistant hard rubber.
The beneficial effects of the utility model are:
1. this funnel stand is provided with the lifting nut of movable lifting between support and middle empty pallet, and middle empty pallet can, according to the big or small up-down adjustment of test occasion and test funnel, facilitate testing crew operation in vertical direction;
2. this funnel stand has designed movable bracket in the middle of middle empty pallet, movable bracket is comprised of uniform trisection or the quartering, each decile is controlled by adjusting accordingly screw rod, so the centre bore of movable bracket can be realized for the size of funnel big or small freely adjusting, the funnel that can extensively be adapted to laboratory plurality of specifications model, has the features such as applied widely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is another view of the utility model structure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The funnel stand of a kind of use for laboratory adjustment height and size, comprise support (1) and the middle empty pallet (2) equipped with support (1), described support (1) upper end is provided with screw thread, described middle empty pallet (2) is provided with lifting nut (5) with support (1) cooperation place, in the middle of described middle empty pallet (2), be fitted with movable bracket (3), described movable bracket (3) coordinates with the adjustment screw rod (4) being arranged on support (1).
Design principle of the present utility model is: movable bracket (3) is split into uniform 3-4 decile, each decile all has the adjustment of independent adjustment screw rod (4), several deciles, according to adjusting the propelling of screw rod (4) or the centre bore that release is combined into different sizes, so just can adapt to the funnel of different size size.
Particularly, during the utility model work, lifting nut (5) can be along support (1) oscilaltion, thereby the oscilaltion of empty pallet (2) in realizing, when funnel is larger, outwards screw out and adjust screw rod (4), owing to adjusting screw rod (4), form screw thread drive connection with hold-down support (20), so drive movable bracket (3) mobile, it is large that movable bracket (3) centre bore becomes, to adapt to larger funnel, when funnel is less, be, inwardly screw rod (4) is adjusted in precession, and movable bracket (3) centre bore diminishes, to facilitate the less funnel of adaptation.
The utility model goes for different funnels, and different liquid receptacle wares has and facilitates advantage easy to assemble, applied widely.
