The novel test tube rack comprises an upper supporting frame, a middle supporting frame, a lower bracket and a connecting rod, wherein the connecting rod is fixedly connected with the upper supporting frame, the middle supporting frame and the lower bracket; the connecting rod is higher than the upper supporting frame, and a higher part of the connecting rod is connected with a carrying handle; symmetric test tube insertion holes are respectively formed in the upper supporting frame and the middle supporting frame; the hole diameters of the test tube insertion holes are equal to the outer diameters of test tubes; a pored rubber plug into which a thermometer can be inserted is arranged on a part, close to the connecting rod, of the upper supporting frame; a thermometer positioning hole is formed in the middle supporting frame; the pored rubber plug corresponds to the thermometer positioning hole; test tube positioning holes are formed in the lower bracket; all insertion holes in the upper supporting frame and the middle supporting frame correspond to one another; the test tube insertion holes correspond to the test tube positioning holes in the lower bracket; the upper supporting frame, the middle supporting frame and the lower bracket are circular. The novel test tube rack is labor-saving, time-saving and safe.
Description
Technical field
The utility model relates to a kind of experimental apparatus, the rack for test tube that particularly a kind of novel heating water bath is used.
Background technology
The operation that often has test tube to heat in water-bath on student experimenting class.Common operator clamps test tube with test tube clamp and is then placed in water-bath, such operation must be operator's hand-held test tube clamp in whole water-bath process, and not so test tube will tilt in water-bath, is easy to slip in water, cause the solution in test tube to flow out, experiment is counted out.A water-bath, is all often that many students share, and a lot of people are crowded together hand-held test tube clamp, to experiment, cause very large inconvenience.In addition, many experiments all need to know the temperature of water-bath, at present the good method of neither one, place the thermometer of surveying bath temperature, can only with hand examination, touch water-bath by rule of thumb, estimate a general temperature, certainly will cause like this inaccuracy of experimental result.The shape of existing rack for test tube is not suitable for putting into water-bath, and a plurality of test tubes of heating water bath simultaneously, can not survey water temperature simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of a plurality of test tubes of heating water bath simultaneously, and can survey the rack for test tube of water temperature simultaneously.
The utility model is achieved in that a kind of a plurality of test tubes of heating water bath simultaneously, and can survey the rack for test tube of water temperature simultaneously, comprises upper bracket, medium-height trestle, bottom bracket, connecting rod four parts, and connecting rod is fixedly connected with upper bracket, medium-height trestle and bottom bracket.Connecting rod exceeds upper bracket, and the raised area connects a carrying handle.On upper bracket, medium-height trestle, be respectively equipped with symmetrical test tube jack, the aperture of test tube jack is suitable with the external diameter of test tube, at upper bracket, near connecting rod place, be provided with a rubber stopper with holes, thermometer can insert in rubber stopper, medium-height trestle is provided with thermometer locating hole, and perforated rubber stopper is corresponding with thermometer locating hole.Bottom bracket is provided with test tube locating hole.Upper bracket is corresponding with all jack positions of medium-height trestle, and test tube jack is also corresponding with the position of the test tube locating hole of bottom bracket.
Of the present utility model being characterised in that, upper bracket, medium-height trestle, bottom bracket are circular, are highly suitable in water-bath and use.
All test tube jacks of upper bracket, medium-height trestle are symmetrical, increase the steadiness of rack for test tube.
Upper bracket, medium-height trestle have corresponding test tube jack, and bottom bracket has test tube locating hole, can guarantee like this stability of test tube when heating water bath.
On support, there are a plurality of jacks, can meet the requirement of heating water bath simultaneously of a plurality of test tubes.
The position that connecting rod exceeds upper bracket is designed to handle, can easily rack for test tube be put into water-bath, also can easily rack for test tube be extracted in water-bath.
At upper bracket, near connecting rod place, be respectively provided with a rubber stopper with holes, can guarantee stability and the security of thermometer in whole water-bath process.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In figure, 1. upper bracket, 1a. test tube jack, 1c. thermometer, 1d. perforated rubber stopper, 2. medium-height trestle, 2a. test tube jack, 2a
1. thermometer locating hole, 3. bottom bracket, 3a. test tube locating hole, 4. connecting rod, one end of 4b. connecting rod, 5. handgrip.
The specific embodiment
Below in conjunction with accompanying drawing, at length the utility model is illustrated.
The utility model is a kind of rack for test tube of using for heating water bath, by upper bracket 1, medium-height trestle 2, bottom bracket 3, connecting rod, forms 4.Connecting rod 4 connect upper brackets 1, in 2 and bottom bracket 3.One end 4b of connecting rod 4 exceeds upper bracket 1, and handgrip 5 is fixed on exceeding on end 4b of connecting rod.On upper bracket, be connected with a rubber stopper 1d with holes, in this rubber stopper 1d, be inserted with thermometer 1c, medium-height trestle 2 is provided with a thermometer locating hole 2a
1, perforated rubber stopper 1d. and thermometer locating hole 2a
1corresponding.On upper bracket 1, be also provided with symmetrical a plurality of test tube jack 1a(jack quantity and can be made as 6 or 8), the external diameter of test tube jack 1a aperture and test tube is suitable, on medium-height trestle 2, be also provided with a plurality of test tube jack 2a, test tube jack 2a aperture is also suitable with the external diameter of test tube.Bottom bracket 3 is provided with a plurality of test tube locating hole 3a, and test tube jack 1a, test tube jack 2a and test tube locating hole 3a are mutually corresponding.During use, the test tube that installs reagent is inserted in test tube jack 1a, test tube jack 2a, hold handgrip 5, rack for test tube is put into water-bath.The utility model can avoid several operators to squeeze around a water-bath simultaneously; Also can avoid operator's hand-held test tube clamp always in whole water-bath experimentation; After water-bath is complete, can hold handgrip 5, at any time rack for test tube be proposed from water-bath, needn't worry to scald one's hand.Easy to use, save time, laborsaving, safety.
