Description
Technical field
A kind of rack for test tube is the utility model is related to, belongs to experimental instrument technology.
Background technology
Rack for test tube is one of most common chemical experimental instrument, and it is mainly used for playing test tube support, placed,
It is a very useful instrument in experimental implementation.
In research work, it is sometimes necessary to the test tube just cleaned is inverted on rack for test tube and carries out drying processing, is tried
The mouth of pipe often directly contacts the bottom plate face of rack for test tube, and test tube interior is easy to be contaminated；The water droplet dripped in dry process is straight
Connect in the bottom plate for flowing to rack for test tube, when water is more, can also be flowed to along bottom plate outside rack for test tube, to other experimental facilities
Pollute.
In addition, test tube of the prior art, can play a part of be only test tube is played one straight up or to
Under placement purposes, there is no fixing function to test tube, when needing to vibrate invisible spectro material manually, mix, shake up
During operation, test tube can only be taken out one by one, the operations such as completion is vibrated, mixed, shaking up, then put back to rack for test tube again.So
Operation, not only time-consuming for experiment, and efficiency is low, and during test tube is taken out and puts back to, its original is on rack for test tube
Position be easy to be placed mistake, cause experiment to go wrong.
Therefore, a kind of new technology of exploitation is needed badly, to solve problems of the prior art.
Utility model content
In order to solve the above problems, the utility model provides a kind of rack for test tube, including connected by support body upper strata, in
Layer, bottom；Fixed test tube hole corresponding to having on upper strata and middle level；The test tube hole in middle level is inverted round table shape, the test tube in middle level
The internal diameter in hole diminishes from top to bottom；Bottom is collecting tank.
In one embodiment, the height of the test tube hole in the middle level is 0.5cm-2cm.
In one embodiment, guide rail is provided with two parallel edges on the upper strata of the rack for test tube, guide rail is provided with
The stair shape framework that can be dismantled and move；The test tube hole on upper strata arranges arrangement, and each row's test tube hole is located at the stair shape frame
Between two stair rods of frame.
In one embodiment, each stair rod of the stair shape framework is vertically connected on two parallel branch simultaneously
On stay.
In one embodiment, fixing device is provided with the guide rail of the rack for test tube, stair shape framework can consolidated
The a certain position being scheduled on guide rail.
In one embodiment, the fixing device is buckle.
In one embodiment, the collecting tank be seamlessly connected by 4 pieces of mutually level baffle plates and rectangle bottom plate and
Into.
The beneficial effects of the utility model：
(1) rack for test tube of the present utility model, the test tube hole in middle level is inverted round table shape, and the internal diameter in hole diminishes from top to bottom；
When the test tube just cleaned, which is inverted in, to carry out drying processing on rack for test tube, because the internal diameter in hole diminishes, the port card of test tube exists
The center section of middle level test tube hole, the bottom plate face of rack for test tube will not be directly contacted, so as to prevent test tube interior to be easy to
Contaminated problem.
(2) rack for test tube of the present utility model, bottom use the set-up mode of collecting tank；The water droplet dripped in dry process is straight
Connect on the collecting tank for flowing to rack for test tube, without being flowed to along bottom plate outside rack for test tube, it is therefore prevented that water flows out and caused to it
Its experimental facilities is polluted or damaged.
(3) rack for test tube of the present utility model, upper strata are provided with the stair shape framework that can be dismantled and move；The test tube hole in middle level
Arrangement is arranged, each row's test tube hole is located between two stair rods of the stair shape framework；When needing to invisible spectro material
When the operation such as being vibrated, mixed, being shaken up manually, it is not necessary to which test tube is taken out to completion these operations one by one, it is only necessary to
Stair shape framework is entered into line slip along guide rail, make the stair rod of stair shape framework and test tube are adjacent, produce certain pressure and
Frictional force, then stair shape framework is fixed on this position with buckle；Because the stair rod of stair shape framework produces to test tube
Raw certain pressure, test tube will not occur in test tube hole it is violent rock, vibrate, mix, shake up etc. and to operate so as to facilitate
Progress；Meanwhile it also avoid experiment error caused by test tube places mistake.
Brief description of the drawings

Fig. 2 is the schematic diagram of the front view of rack for test tube of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1-2, it is the schematic diagram of rack for test tube of the present utility model.
Rack for test tube of the present utility model, including connected by support body 1 upper strata 4, middle level 2, bottom 3；On upper strata 4 and middle level 2
Fixed test tube hole corresponding to having；The test tube hole 5 in middle level 2 is inverted round table shape, and the internal diameter in hole diminishes from top to bottom；Bottom 3 is
Collecting tank.
Alternatively, the collecting tank is seamlessly connected with rectangle bottom plate by 4 pieces of mutually level baffle plates and formed.
Alternatively, guide rail 7 is provided with two parallel edges on the upper strata 4 of the rack for test tube, guide rail 7 is provided with and can dismantled
With mobile stair shape framework 6；The test tube hole on upper strata 4 arranges arrangement, and each row's test tube hole is located at the two of the stair shape framework 6
Between individual stair rod.
Alternatively, each stair rod of the stair shape framework 6 is vertically connected on two parallel support bars simultaneously.
Alternatively, fixing device, such as buckle are provided with the guide rail 7 of the rack for test tube, stair shape framework can consolidated
The a certain position being scheduled on guide rail.
Operation principle of the present utility model：
First, for test tube airing：
Test tube is inverted, is inserted into from the test tube hole on upper strata in the test tube hole in middle level.Because the test tube hole in middle level is inversion
Round table-like, the internal diameter in hole diminishes from top to bottom；When the test tube just cleaned, which is inverted in, to carry out drying processing on rack for test tube, due to
The internal diameter in hole diminishes, and the port card of test tube will not directly contact the bottom plate of rack for test tube in the center section of middle level test tube hole
Face, so as to prevent test tube interior to be easy to contaminated problem.In addition, bottom can be by the way of collecting tank；Dried
The water droplet dripped in journey is flowed directly on the collecting tank of rack for test tube, without being flowed to along bottom plate outside rack for test tube, it is therefore prevented that
Water flows out and causes other experimental facilities are polluted or damaged.
2nd, the vibration for the test tube equipped with liquid, mix, shake up：
Test tube equipped with liquid is inserted into the test tube hole in middle level from the test tube hole on upper strata.By stair shape framework along leading
Rail enters line slip, makes that the stair rod of stair shape framework and test tube are adjacent, produce certain pressure and frictional force, then by stair shape
Framework is fixed on this position with buckle；Because the stair rod of stair shape framework produces certain pressure to test tube, test tube is not
Can occur in test tube hole it is violent rocks, so as to facilitate the progress for vibrating, mixing, the operation such as shaking up.
Although the utility model is disclosed as above with preferred embodiment, it is not limited to the utility model, any
Person skilled in the art, is not departing from spirit and scope of the present utility model, can all do various change and modification, therefore this
What the protection domain of utility model should be defined by claims is defined.
