However, the food samples may be contaminated or deteriorated if they come into contact with air or moisture during storage, which may affect the test results.
[0003] For reference Figures 1-3 The original food sample storage box has a box body 1 and a box cover 2. The box cover 2 is rotatably connected to the box body 1 at one end. The other end of the box cover 2 is provided with a buckle 3 for locking with the box body 1 when the box cover 2 is closed. A tube rack 4 is placed in the box body 1. The tube rack 4 is provided with a plurality of sample tubes 5. The tube rack 4 includes a lower flat plate 4-1 and an upper flat plate 4-2.

Therefore, the sample tubes 5 may shake and collide when the storage box is moved, transported, or carried.
[0006] Third, since there is also a 0.5 mm gap between the sample tubes 5 and the insertion holes 4-21, the sample tubes 5 and the tube rack 4 will move up and down relative to each other. When the sample tubes 5 move upward in the insertion holes 4-21 of the tube rack 4, they will hit the box cover 2. When they fall, they will collide with the lower flat plate 4-1. Therefore, the sample tubes 5 may shake and collide when the storage box is moved, transported, or carried.
[0007] Fourth, the tube rack 4 is inserted into the box body 1 or taken out from the box body 1, and the hand is not good to hold, the operation is not safe, and it is not convenient. Utility model content

[0035] The utility model will be further described below in combination with the drawings and examples:
[0036] Example one: can see Figures 4-12 A food sample storage box, comprising a box body 1 and a box cover 2, one end of the box cover 2 is rotatably connected with the box body 1, the other end of the box cover 2 is provided with a buckle 3 for locking with the box body 1 when covering, a tube rack 4 is placed in the box body 1, a plurality of sample tubes 5 are inserted on the tube rack 4, and the key point is:
[0037] The box cover 2 is provided with two tube rack pressing plates 6 for pressing the left and right sides of the tube rack 4 respectively and a sample tube pressing cover 7 for pressing each sample tube 5; the sample tube pressing cover 7 is located between the two tube rack pressing plates 6, and the two ends of the sample tube pressing cover 7 are slidably connected with the two tube rack pressing plates 6, and a spring 8 is arranged between the sample tube pressing cover 7 and the inner top wall of the box cover 2.
[0038] The working principle of the embodiment is as follows: in the open state of the box cover 2, the tube rack 4 with a plurality of sample tubes 5 inserted is first placed in the box body 1, then the box cover 2 is turned to cover completely, and then the buckle 3 is locked to achieve storage.
[0039] During the turning of the box cover 2 to cover, the two tube rack pressing plates 6 inside the box cover 2 will press the left and right sides of the tube rack 4 respectively, and the sample tube pressing cover 7 will press all the sample tubes 5 on the tube rack 4. Because the spring 8 exerts an elastic force on the sample tube pressing cover 7, and the two ends of the sample tube pressing cover 7 are slidably connected with the two tube rack pressing plates 6, the sample tube pressing cover 7 elastically presses all the sample tubes 5 in a floating manner rather than rigidly contacting and pressing, which not only ensures that the normal pressing function can be smoothly realized, but also avoids hard contact damage to the sample tubes 5. In particular, it can avoid the problem that when the two tube rack pressing plates 6 press the left and right sides of the tube rack 4, the sample tube pressing cover 7 cannot press all the sample tubes 5 on the tube rack 4, and the floating elastic pressing can overcome this problem.
[0040] In addition, in the embodiment, the tube rack 4 is stably pressed and relatively fixed in the box body 1 by being pressed left and right by the two tube rack pressing plates 6, which can limit the relative movement between the tube rack 4 and the box body 1 in the left and right, front and back, and up and down directions, thereby reducing or avoiding the problem that the sample tubes 5 will shake and collide when the storage box is moved, transported or carried;
[0041] At the same time, since the sample tube 5 is pressed by the sample tube pressing cover 7 on the tube rack 4, the sample tube 5 is in the insertion hole 4-21 of the tube rack 4 and is limited to relative movement between the sample tube 5 and the tube rack 4, and when the sample tube 5 moves upward in the insertion hole 4-21 of the tube rack 4, the sample tube 5 will collide with the box cover 2, thereby further reducing or avoiding the problem that the sample tube 5 will shake and collide when the storage box is moved, transported or carried.
[0042] Therefore, the embodiment can solve the technical problems that the sample tube and the tube rack, and the tube rack and the box body or / and the box cover are prone to shake and collide with each other.

[0046] When the box cover 2 is in the closed state, please refer to Figures 7-10 The insertion part 6-1 of the lower end of the two tube rack pressing plates 6 is inserted into the two notches 4-22 of the upper plate 4-2 of the tube rack 4, respectively, which can realize left and right insertion positioning and can avoid the displacement of the tube rack 4 and the box cover 2 or the box body 1. When the sample tube pressing cover 7 presses the sample tube 5 on the tube rack 4, the sample tube pressing cover 7 will slide upward relative to the guide rod 6-3, so that the spring 8 is further compressed, the elastic pressure is increased, and the position of the sample tube pressing cover 7 is determined according to the height of the cap top surface of the sample tube 5, and the spring 8 is automatically contacted and pressed, without additional manual operation.
[0047] When the box cover 2 is in the open state, please refer to Figures 11-12 After the sample tube pressing cover 7 is separated from the sample tube 5, the sample tube pressing cover 7 is finally blocked and constrained by the step surface of the contact position of the tube rack pressing plate 6 and the guide rod 6-3 under the action of the spring 8, and is automatically reset to the normal state, without additional manual operation.
[0048] Therefore, in the embodiment, only the box cover 2 needs to be rotated when the box cover 2 is stored and closed or opened, which is completely consistent with the use method of the prior art, and does not increase the trouble.
[0049] In addition, the two symmetrical notches 4-22 on the upper plate 4-2 of the tube rack 4 are very ingenious, which can cooperate with the insertion parts 6-1 at the lower end of the two tube rack pressing plates 6 to realize positioning and compression, reduce the risk of loosening, and when the box cover 2 is opened, the insertion parts 6-1 of the two tube rack pressing plates 6 will be away from the two notches 4-22, and at this time, the two notches 4-22 are held with both hands, and the tube rack (4) and the sample tubes (5) thereon can be easily taken out as a whole; in addition, the two notches 4-22 can also be held when the tube rack (4) and the sample tubes (5) thereon are put into the box body, and the two notches 4-2 are more loaded and stably stored, which plays multiple functions and different effects, and does not affect normal use.
[0050] See Figure 4 Further, the upper end of each tube rack pressing plate 6 is fixed to the inner top wall of the box cover 2 through two guide rods 6-3; the two guide rods 6-3 are arranged in parallel and spaced apart. The two ends of the sample tube pressing cover 7 are each in sliding cooperation with the two guide rods 6-3 (in combination with Figures 7-8 ), and are each acted on by two springs; that is, the sample tube pressing cover 7 is in sliding cooperation with four guide rods 6-3 and is acted on by four springs, which can improve the compression force and make the sliding more stable.
[0051] Embodiment three: this embodiment is basically the same as embodiment one or two, the difference lies in that:
[0052] See Figures 5-10 Further, the compression surface of the sample tube pressing cover 7 is provided with a first counterbore 7-2 for positioning and compression of the cap 5-1 of the sample tube 5. When closed, the first counterbore 7-2 cooperates with the cap 5-1 of the sample tube 5 to realize positioning and compression, double constraint effect, and avoid radial loosening.
[0053] See Figures 5-10 Further, the first counterbore 7-2 has a first elastic sleeve or a first elastic layer 7-3. Since the elastic material (such as rubber material) is in contact with the cap 5-1 of the sample tube 5, damage can be avoided, and a buffering protection effect can be achieved.
[0054] See Figures 5-10 Further, an upper surface of the lower plate 4-1 of the tube rack 4 is provided with a second counterbore 4-11 for positioning and compression of the bottom 5-2 of the sample tube 5. When in use, the second counterbore 4-11 cooperates with the bottom end of the sample tube 5 to realize positioning and compression, double constraint effect, and avoid radial loosening.
[0055] See Figures 5-10Further, the second sink hole 4-11 has a second elastic cap or a second elastic layer 4-12. Since the elastic material (such as rubber) is in contact with the bottom end 5-1 of the sample tube 5, damage can be avoided, and buffering protection can be achieved.
