Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
As shown in Figs 1-4, the utility model includes pedestal 1 and pieces of cloth 2, and pedestal 1 is equipped with 3, two couples of 4 and of supporting block of sandbox
Two columns 5 are rotatably equipped with shaft 6 between each pair of supporting block 4, for each pair of supporting block 4, in one of supporting block 4
Equipped with screw hole 7, screw rod 8 is screwed in screw hole 7, the inner end of screw rod 8 is pushed against in shaft 6, and two columns 5 are located at two pairs of supports
Between block 4, cross bar 9 is equipped between every column 5, two cross bars 9 and two shafts 6 are parallel to each other, and sandbox 3 is located at two opposition
Between column 5, sand is loaded in sandbox 3；One end of pieces of cloth 2 is fixed therein in a shaft 6, and the other end of pieces of cloth 2 is successively
From the upside of two cross bars 9 around being wound in another shaft 6 later, on pieces of cloth 2 from one end close to a wherein shaft 6 to
One end close to another shaft 6 is successively arranged multiple groups test tube hole 10, and the diameter of each group test tube hole 10 is all different, same group of examination
The aperture of all test tube holes 10 in pore 10 is identical.
As depicted in figs. 1 and 2, one end of shaft 6 is installed with knob 11 after passing outwards through supporting block 4.Knob 11, side are set
It will pass through 11 rotating shaft 6 of knob, keep rotating shaft 6 more convenient.
As shown in Fig. 2, knob 11 is equipped with skid resistance strip 12.Skid resistance strip is arranged by antiskid effect in skid resistance strip 12
12, it is more convenient when rotating knob 11.
As shown in Fig. 2, from pieces of cloth 2 close to one end of a wherein shaft 6 to pieces of cloth 2 close to one end of another group of test tube,
The diameter of each group test tube hole 10 is incremented by successively.It only needs to a direction rotating shaft 6, by the test tube hole 10 right above sandbox
Aperture will be gradually increased or be gradually reduced, the test tube hole 10 of suitable diameter easy to find.
As shown in figures 1 and 3, bearing 13 is installed in each column 5, cross bar 9 is rotatably connected by bearing 13
On column 5.When cloth is mobile relative to cross bar 9, cloth can and cross bar 9 generate friction, cross bar 9 can with the movement of cloth and
Rotation reduces cross bar 9 to the resistance of cloth, cloth movement is made to get up more smoothly.
When using a kind of rack for test tube provided by the utility model, suitable dust-free sterile sand is contained in sandbox 3 first,
