[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a test tube storage device, including a box body 1, a foam frame 2 is installed inside the box body 1, support frames 3 are installed on both sides corresponding to each other inside the foam frame 2, a test tube rack 4 is inserted on the tops of the two support frames 3, a plurality of test tube holes 5 are opened inside the test tube rack 4, test tube bodies 6 are inserted inside the plurality of test tube holes 5, a cooling groove 13 is opened inside the box body 1 and on one side of the foam frame 2, an ice pack 14 is placed inside the cooling groove 13, which is convenient for reducing the temperature inside the box body 1 and the foam frame 2, and avoiding the deterioration of the sample inside the test tube body 6. A heat preservation board 15 is installed inside the box body 1 and on one side of the cooling groove 13, which is beneficial to strengthening the heat preservation and heat insulation effect of the box body 1. A tube cap 7 is arranged on the top of the test tube body 6. A plurality of sliding grooves 9 are opened on the outside of the plurality of test tube holes 5 inside the test tube rack 4, positioning rods 10 are slidably connected inside the plurality of sliding grooves 9, one end of the positioning rod 10 extends into the test tube hole 5, one end of the positioning rod 10 is provided with an inclined surface, a first spring 11 is installed inside the sliding groove 9, and one end of the first spring 11 is connected to the other end of the positioning rod 10. Under the action of the inclined surface at one end and the deformation of the spring at the other end, when the inclined surface at one end of the positioning rod 10 is squeezed by the test tube body 6, it can automatically displace, which is convenient for clamping and fixing test tube bodies 6 of different sizes, and is beneficial to preventing the test tube body 6 from detaching when the box body 1 is collided by an external force. A high-density sponge pad 12 is laid at the bottom of the support frame 3 inside the foam frame 2, which can absorb the flowing liquid sample and prevent it from leaking outwards. A box cover 8 is installed on the top of the box body 1, and a sealing gasket 22 is installed on the inner side of the box cover 8, which is beneficial to improving the sealing performance between the box body 1 and the box cover 8. A positioning groove 16 is opened inside the support frame 3, a fixed insertion hole 17 is opened inside the support frame 3 and on one side of the positioning groove 16. Positioning members 23 are installed on both sides corresponding to each other at the bottom of the test tube rack 4, the positioning members 23 are inserted into the positioning groove 16, a limiting groove 18 is opened inside the positioning member 23, a bolt 19 is slidably connected inside the limiting groove 18, one end of the bolt 19 is arc-shaped, one end of the bolt 19 is inserted into the fixed insertion hole 17, a second spring 20 is installed inside the limiting groove 18, and one end of the second spring 20 is connected to the other end of the bolt 19. When the positioning member 23 is inserted into the positioning groove 16, the arc surface at one end of the bolt 19 inside the positioning member 23 is squeezed and automatically moves backwards, and squeezes the second spring 20 to deform it. When the bolt 19 displaces to the position of the fixed insertion hole 17, the second spring 20 pushes the bolt 19 to reset, and makes one end of it inserted into the fixed insertion hole 17 to fix the bolt 19. Similarly, for the reverse operation, when the test tube rack 4 is pulled out upwards, the bolt 19 can be pulled out of the fixed insertion hole 17 to release the fixation between the positioning member 23 and the support frame 3, which is convenient for the installation and disassembly of the test tube rack 4. Handles 21 are installed on both sides corresponding to each other at the top of the test tube rack 4, which is convenient for holding the test tube rack 4.

[0022] In summary, for this test tube storage device, during use, place the test tube rack 4 in the foam frame 2 inside the box body 1. After it is positioned above the foam frame 2 and the two support frames 3, press the test tube rack 4 so that the bottom positioning member 23 thereof is inserted into the positioning groove 16 inside the support frame 3. At the same time, the arc surface at one end of the plug 19 protruding inside the positioning member 23 is automatically pushed backward by the extrusion of the positioning groove 16. When it reaches the position of the fixed insertion hole 17 on one side of the positioning groove 16, under the action of the second spring 20 at the other end of the plug 19, the plug 19 is pushed to reset, and one end of it is inserted into the fixed insertion hole 17, fixing the support frame 3 and the test tube rack 4 together. Similarly, since a plurality of test tube holes 5 are formed inside the test tube rack 4, and a plurality of sliding grooves 9 are provided on one side of the plurality of test tube holes 5 inside the test tube rack 4, a positioning rod 10 is slidably connected inside each of the plurality of sliding grooves 9. One end of each of the plurality of positioning rods 10 is located inside the test tube hole 5 and is beveled. Therefore, when the test tube body 6 containing the liquid food sample is inserted into the test tube hole 5, the bevel surfaces at one ends of the plurality of positioning rods 10 are automatically pushed backward by the extrusion, squeezing the first spring 11 at the other end, deforming it. The first spring 11 pushes the positioning rod 10 to clamp the test tube body 6. By repeating the operation, a plurality of test tube bodies 6 can be respectively fixed in a plurality of test tube holes 5. Covering the box cover 8 on the box body 1 can store the plurality of test tube bodies 6. According to requirements, an ice pack 14 can be placed in the cooling groove 13 inside the box body 1 to reduce the temperature inside the box body 1 and the foam frame 2. At the same time, a high-density sponge pad 12 is laid at the bottom of the plurality of test tube bodies 6 inside the foam frame 2. Therefore, when the test tube body 6 leaks the sample due to damage or poor sealing, the high-density sponge pad 12 quickly absorbs the sample liquid.
