[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a sample storage device for food testing, including a storage box 1 and a storage cabinet 19. Four groups of first mounting slots 2 are opened at the lower part of the storage box 1. Universal wheels 3 are installed with threads inside the first mounting slots 2 to facilitate the movement of the lowermost storage box 1. Four groups of second mounting slots 4 are opened at the lower part of the storage box 1. A support frame 5 is rotatably installed inside the second mounting slot 4. A contact plate 6 is installed on the inner rotating shaft of the lower part of the support frame 5. When the support frame 5 is rotated to a vertical direction and the contact plate 6 inside the support frame 5 is rotated to a horizontal direction, the contact plate 6 makes the universal wheel 3 leave the ground to ensure the fixation of the storage box 1. A threaded hole is opened in the middle of the contact plate 6 12. Four groups of threaded rods 13 that match the threaded holes 12 are rotatably installed on the upper side of the storage box 1. A rotating disk 14 is fixedly welded to the outer side of the lower part of the threaded rod 13. By rotating the rotating disk 14, the threaded rod 13 is rotated into the threaded hole 12 at the lower part of the upper storage box 1 to complete the connection between the upper and lower groups of storage boxes 1. Friction lines are provided on the outer side of the rotating disk 14 to facilitate rotating the rotating disk 14 in a narrow space. An embedding groove 15 is provided on one side of the storage box 1. An embedding block 16 that matches the embedding groove 15 is fixedly welded on the other side of the storage box 1. The two groups of storage boxes 1 are connected by inserting the embedding block 16 of the storage box 1 on one side into the embedding groove 15 of the storage box 1 on the other side.

[0022] Four sets of fixing plates 7 are fixedly welded to the lower part of the storage box 1. The height of the fixing plates 7 is less than the extended height of the universal wheels 3. A locking rod 9 is slidably installed inside the fixing plates 7. A locking hole 11 that cooperates with the locking rod 9 is opened inside the support frame 5 to ensure that the support frame 5 is fixed in the vertical direction and can block the second installation slot 4 to prevent the retracted support frame 5 from escaping from the second installation slot 4; a fixing piece 8 is fixedly welded to one end of the locking rod 9, and a spring 10 is fixedly welded between the fixing piece 8 and the fixing plate 7. The spring 10 is sleeved on the outside of the locking rod 9. The spring 10 ensures that the locking rod 9 is inserted into the locking hole 11 by pulling the fixing piece 8; a box door 17 is installed on the front shaft of the storage box 1, and a handle 18 is fixedly welded on the front side of the box door 17 for easy removal of storage Samples in the storage box 1; several groups of mounting rails 20 that match the storage box 1 are fixedly welded inside the storage cabinet 19, which makes it convenient to install the storage box 1 into the storage cabinet 19, refrigerate the storage box 1, and facilitate the preservation of samples. Grooves 21 are provided at the upper and lower ends of the mounting rails 20 to facilitate the insertion of the universal wheels 3 and the threaded rods 13; a rotating shaft 22 is rotatably installed on both sides of the lower part of each group of mounting rails 20, and a limiting plate 23 is fixedly welded at the other end of the rotating shaft 22. A torsion spring 24 is fixedly welded between the limiting plate 23 and the mounting rail 20, and the torsion spring 24 is sleeved on the outside of the rotating shaft 22. The torsion spring 24 drives the rotating shaft 22 to rotate, so that the limiting plate 23 remains in the vertical direction, which is used to shield the storage box 1 and prevent the storage box 1 from detaching from the mounting rail 20.

[0023] Working principle: When the utility model is in use, the storage box 1 is taken out from the inside of the storage cabinet 19, and the support frame 5 is rotated to the vertical direction. The spring 10 ensures that the locking rod 9 is inserted into the locking hole 11 by pulling the fixing plate 8, so that the support frame 5 is fixed in the vertical direction, and the contact plate 6 inside the support frame 5 is rotated to the horizontal direction. The contact plate 6 makes the universal wheel 3 leave the ground, ensuring that the storage box 1 is fixed. By rotating the rotating disk 14, the threaded rod 13 is rotated to the threaded hole 12 at the bottom of the upper storage box 1 to complete the connection between the upper and lower groups of storage boxes 1. By inserting the embedding block 16 of the storage box 1 on one side into the embedding groove 15 of the storage box 1 on the other side, the connection between the left and right groups of storage boxes 1 is realized, and the universal wheel 3 of the lowest storage box 1 is exposed, which is convenient for transporting the storage box 1.
