[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-2 This utility model provides an embodiment of a portable support for chemical engineering experiments, including a shell 1 for connecting various components. A test tube rack assembly 2 is provided on the upper part of the shell 1 for holding test tubes used in chemical engineering experiments. A storage groove 11 is provided in the middle of the shell 1 for storing the test tube rack assembly 2. The height of the storage groove 11 is the same as the thickness of the support plate 22 and the frame plate 21 after folding. It can limit the position of the frame plate 21 and the support plate 22. The test tube rack assembly 2 includes a frame plate 21. Support plates 22 are provided on the left and right sides of the bottom surface of the frame plate 21. The frame plate 21 and the two support plates 22 can together form a test tube rack.

[0027] Furthermore, the bottom of the shelf plate 21 is fixedly connected to an installation strip 212, which is used to connect with the support plate 22. The front and rear parts of the installation strip 212 are provided with installation ports 213, which are used to connect with the connecting blocks 222. The top of the support plate 22 is fixedly connected with two connecting blocks 222. The middle of the two connecting blocks 222 is rotatably connected to a connecting shaft 223, which is used to connect the support plate 22 and the shelf plate 21. The connecting shaft 223 passes through and is rotatably connected to the installation strip 212. The middle of the shelf plate 21 has a first test tube port 211, which is used to place larger reagent tubes when the test tube rack is opened. The middle of the support plate 22 has a second test tube port 221, which is used to place smaller reagent tubes when the test tube rack assembly 2 is closed.

[0028] like Figures 3-4 As shown, the top surface of the outer shell 1 is fixedly connected to the left and right sides of the top surface with a limiting frame 14. The middle part of the shell has a groove that matches the support plate 22. The lower part of the support plate 22 is inserted into the limiting frame 14. The front left and right sides of the storage groove 11 are provided with connecting grooves 13, which are used to cooperate with various components. The diameter of the opening side is smaller than the diameter of the locking bead 12, and the inner wall diameter is adapted to the locking bead 12. The locking bead 12 is slidably connected in the middle of the connecting groove 13, which is used to cooperate with the limiting position when the test tube rack assembly 2 is retracted. The locking bead 12 and the connecting groove 13 are fixedly connected together with a spring 15.

[0029] Working principle: When in use, if the support needs to be folded up, simply pull the test tube rack assembly 2 towards the upper part of the outer shell 1, so that the two support plates 22 are disengaged from the limiting frame 14. Then, fold the two support plates 22 towards the frame plate 21, so that the support plates 22 and the frame plate 21 are folded up. Then push the folded test tube rack assembly 2 into the storage slot 11. The sides of the frame plate 21 and the support plates 22 push the locking bead 12 together, thereby squeezing the spring 15 and pushing the locking bead 12 into the connecting slot 13, so that the test tube rack assembly 2 can be completely installed into the storage slot 11. When the test tube rack assembly 2 is completely installed into the storage slot 11, the spring 15 will push the locking bead 12 to reset, so that the locking bead 12 is locked in front of the folded test tube rack assembly 2 to restrict its position.

[0030] Meanwhile, if it is necessary to use the stand to place smaller reagent tubes, simply invert the outer shell 1 so that the two limiting frames 14 are in contact with the table or ground, and then insert the smaller reagent tube into the second test tube opening 221 on the test tube rack assembly 2.

[0031] If you need to use the test tube rack assembly 2, simply pull the test tube rack assembly 2 outward to detach it from the storage slot 11, then open the rack plate 21 and the support plate 22, and then insert the two support plates 22 into the two limiting frames 14 respectively. Then place the outer shell 1 on the table or the ground, and then insert the larger test tube into the first test tube opening 211.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
