Figure 1 is the structure schematic diagram of the test tube water bath heat preservation device of the utility model.
Fig. 2 is a schematic connection diagram of the limiting rod and the connecting rod of the present invention.
In the figure, 1-a water bath box, 2-upright posts, 3-cross rods, 4-sliding channels, 5-limiting rods, 6-sliding chutes, 7-test tube holes, 8-connecting rods, 9-floating plate frames and 10-floating plate bodies.
Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and examples in the present application may be combined with each other without conflict.
The utility model relates to a typical embodiment provides a test tube water bath heat preservation device, as shown in figure 1, including water bath 1 and test tube support. The test tube support comprises a support frame and a floating plate, wherein the support frame comprises four stand columns 2 and a cross rod 3 fixedly connected with the stand columns 2. A sliding channel 4 is formed in the upright column 2 along the height direction of the upright column, a limiting rod 5 capable of sliding up and down along the sliding channel 4 is arranged in the sliding channel 4, and a sliding chute 6 communicated with the sliding channel 4 is formed in the side surface of the upright column 2; be provided with a plurality of test tube holes 7 that are used for fixed test tube on the kickboard, four bights of kickboard are provided with connecting rod 8, and connecting rod 8 links to each other with 5 middle parts of gag lever post.
In this embodiment, the kickboard can float on the surface of water, and when the liquid level altitude changed in the water bath 1, it reciprocated to drive the test tube by the kickboard to the lower part keeps relatively stable with interior and the test tube height that soaks of surface of water all the time in guaranteeing the test tube, thereby guarantees the reliability of experiment.
In addition, because the bottom of some water bath boxes is provided with a heating or heat conducting fastener, if the bottom of the test tube contacts the bottom of the water bath box, the sample is too high; with plastic test tubes, there is also a risk that the test tube will be damaged by melting.
