Description
Technical field
The utility model is related to chemical experiment instrument field, and specially a kind of high school student is with convertible test tube drying frame.
Background technology
Relatively easy due to testing in high school chemical experiment, generally only a small amount of solid or liquid drug progress chemistry is anti-
Should, for observation of students experimental phenomena, this experiment is typically to be carried out in test tube, therefore high school chemical experiment, and test tube is student
One of experiment equipment being in the most contact.After the completion of experiment, experimenter will scrub to test tube, then again by the examination brushed
The pipe mouth of pipe is inserted into downwards rack for test tube overhead solid carbon dioxide point one by one.After test tube dries completely, experimenter will will also try one by one again
Pipe is turned and is reinserted on rack for test tube.Test tube very inconvenience is so dried, it is necessary to take a substantial amount of time wait,
It is very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of high school student with convertible test tube drying frame, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：
A kind of high school student is with convertible test tube drying frame, including base, support bar and test tube rack, the left and right two of base
End, which is arranged between two support bars, two support bars, is provided with test tube rack, and test tube rack includes connecting rod and cross bar,
Two cross bars of connection symmetrical above and below between two connecting rods, two connecting rods are connected in support bar by axis of rotation respectively
Portion, test tube rack can be rotated by rotating shaft with any angle on support bar, corresponding above and below two cross bars to be uniformly provided with
Elastic rubber ring is provided with some test tube holes, test tube hole, the outboard end of a support bar rotates connection connecting pin, connection by shipping and reselling on another market
Pin is L-type structure, and the spacing hole being engaged with connecting pin is provided with close to the connecting rod of connecting pin.
It is corresponding above and below two cross bars uniformly to be tried provided with 5~8 as the utility model further technical scheme
Pore.
Compared with prior art, the utility model is simple in construction, and test tube card is placed on test tube rack, and can stand upside down inclination
Dry, sky does invisible spectro ponding, accelerate test tube and dry speed, it is easy to operate, quick.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the high school student of the utility model with convertible test tube drying frame；
Fig. 2 is a kind of left view of the high school student of the utility model with the drying test tube state of convertible test tube drying frame.
In figure：1- bases, 2- support bars, 3- connecting rods, 4- rotating shafts, 5- cross bars, 6- test tube holes, 7- elastic rubber rings, 8-
Connecting pin, 9- ships and resell on another market, 10- spacing holes.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Fig. 1~2 are referred to, a kind of high school student is placed with convertible test tube drying frame, including base 1, support bar 2 and test tube
Frame, the left and right ends of the base 1, which are arranged between two support bars 2, two support bars 2, is provided with test tube rack,
The test tube rack includes two cross bars 5 of connection symmetrical above and below, two companies between connecting rod 3 and cross bar 5, two connecting rods 3
Extension bar 3 is rotatably connected on the middle part of support bar 2 by rotating shaft 4 respectively, and the test tube rack can be existed by rotating shaft 4 with any angle
Rotated on support bar 2, two cross bars are corresponding about 5 to be uniformly provided with some test tube holes 6, the test tube hole 6 provided with elasticity
Rubber ring 7, the outboard end of a support bar 2 connects connecting pin 8 by 9 rotations of shipping and reselling on another market, and the connecting pin 8 is L-type structure, close to even
The connecting rod 3 of pin 8 is provided with the spacing hole 10 being engaged with connecting pin 8.
The test tube mouth of pipe brushed is inserted into the test tube hole 6 on cross bar 5 one by one upwards, the upper and lower part difference of test tube
Above and below being engaging on two cross bars 5, due to being fixed with elastic rubber ring 7, therefore the outer wall and bullet of test tube on the inwall of test tube hole 6
Property rubber ring 7 contact after have certain frictional force, can slightly be exerted oneself during insertion.After test tube is plugged, due to by elastic caoutchouc
The extruding of circle 7, test tube will not slide because of self gravitation, then tilt test tube rack so that Open Side Down for test tube, now uses
Connecting pin 8 cooperates with spacing hole 10, so that fixed test tube rack so that invisible spectro water, which is directly put upside down, to drain off, convenient
After test tube rapid airing, test tube airing, connecting pin 8 is removed, test tube rack is put down, test tube is taken out, arrangement is put well.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
, can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses
Various changes can be made.
