Description

Technical Field

[0001] The utility model relates to the technical field of cell storage devices, and in particular to a cell storage device with a protective function. Background Art

[0002] A cell storage device generally refers to equipment used to preserve biological samples, cell cultures, and biomedical samples. Currently, most cell storage devices on the market use frozen storage methods, such as placing cells into test tubes, and then placing the test tubes into freezing equipment to complete the cell storage work.

[0003] However, existing cell storage devices generally only provide simple protection for cells and test tubes used to store cells through boxes. Once such storage devices collide during transportation, the test tubes inside them are likely to fall out of the test tube racks, causing the test tubes to hit the boxes, or the test tubes to collide with each other, resulting in test tube breakage and cell damage. Utility Model Content

[0004] The utility model provides a cell storage device with a protective function, which solves the problem in the related art that the test tube hits the box body or the test tubes hit each other.

[0008] Furthermore, a plurality of auxiliary frames are arranged on the frame body, each of the auxiliary frames is fixedly connected to the frame body, and a sliding opening for sliding connection of the second connecting rod is arranged on the auxiliary frame.

[0009] Furthermore, the fixing assembly includes a fixing piece, a fixing slot, and a fixing hole. The fixing slot passes through an end of the auxiliary frame away from the frame body, and the fixing hole is opened at an end of the second connecting rod close to the fixing slot. The fixing piece abuts against the fixing hole and is slidably connected to the fixing slot.

[0010] Furthermore, the fixing member is in a right-angled trapezoidal structure on a vertical projection plane, and one end of the fixing member away from the mounting groove is an upper bottom of the fixing member.

[0011] Furthermore, the reset structure includes a positioning rod, a positioning hole, and an elastic member. The positioning hole is opened at one end of the frame away from the mounting groove. The positioning rod is fixedly connected to the lower pressure body and slidably connected in the positioning hole.

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-2 As shown, this embodiment proposes a cell storage device with a protective function, which mainly includes a box body 1, a test tube rack 2 is arranged inside the box body 1, and the test tube rack 2 includes a plurality of rack bodies 21, each rack body 21 is provided with a mounting groove 211, and each mounting groove 211 is provided with a clamping structure 3, that is, the test tube loaded into the mounting groove 211 is clamped by the clamping structure 3, so as to prevent the test tube inside the box body 1 from being separated from the test tube rack 2 due to the action of inertia when the box body 1 is hit, causing each test tube to hit the box body 1 or the test tube rack 2, or even each test tube hits each other to cause the test tube to be damaged, resulting in damage to the cells inside the test tube, so that this embodiment has protective performance.

[0030] like Figure 3 , Figure 4 , Figure 6 As shown, each clamping structure 3 in this embodiment includes a lower pressure body 31 and a plurality of clamping bodies 32 for clamping test tubes. The lower pressure body 31 is located at the bottom of the installation groove 211 and is slidably connected to the frame body 21. When the test tube is installed in the staff box installation groove 211, the lower pressure body 31 is forced to slide downward, thereby triggering the linkage structure 4 provided between each clamping body 32 and the lower pressure body 31. With the structural characteristics of the linkage structure 4, while transmitting the force brought by the downward pressure of the lower pressure body 31, the direction of the force will be changed, thereby pushing each clamping body 32 to clamp the test tube.

[0031] That is, in the process of installing the test tube, the present embodiment can conveniently control the clamping structure 3 to clamp and fix the test tube, avoiding the need for additional operation on the clamping structure 3 to achieve the fixation of the test tube, thereby improving the convenience of the present embodiment during use; at the same time, an arc-shaped groove should be provided on the lower pressure body 31 to facilitate the cooperation with the test tube, and the arc-shaped structure of the arc-shaped groove can be used to evenly disperse the pressure, reduce the force on the test tube, and prevent the test tube from being damaged during use, thereby improving the safety of the present embodiment.

[0032] The clamping bodies 32 are evenly distributed around the mounting groove 211, so that the clamping force exerted on the test tube by the clamping structure 3 in this embodiment can act evenly on the test tube, and can avoid the existence of clamping dead angles, thereby ensuring the clamping performance of the clamping structure 3; and, the clamping bodies 32 in this embodiment should preferably be made of elastic material, and with the help of the elastic potential energy of the elastic material, the test tube can be avoided from being damaged due to excessive clamping force during the process of clamping the test tube by the clamping structure 3, and the elastic material has certain flexibility and adaptability, and can adapt to test tubes of different shapes and specifications; at the same time, since the interior of the box body 1 may be in a low-temperature environment during storage, in order to ensure the service life of the clamping body 32, the elastic material constituting the clamping body 32 should preferably be made of low-temperature and wear-resistant elastic materials such as fluororubber.

[0033] At the same time, a reset structure 5 is provided between the lower pressure body 31 and the frame body 21, that is, when the staff takes the test tube out of the installation groove 211, the lower pressure body 31 without external force can reset itself, thereby facilitating the secondary use of this embodiment.

[0034] The reset structure 5 in the present embodiment includes a positioning rod 51, a positioning hole 52, and an elastic member 53. The elastic member 53 is fixedly connected between the frame 21 and the lower pressure body 31. The elastic member 53 is preferably a compression spring, that is, the reset structure 5 in the present embodiment is reset by the elastic force of the compression spring. Compared with reset devices such as cylinders and motors, the reset is performed by the elastic force of the spring, which not only reduces the economic cost but also saves the internal space of the frame 21; the positioning hole 52 is opened at one end of the frame 21 away from the installation groove 211, the positioning rod 51 is fixedly connected to the lower pressure body 31 and slidably connected in the positioning hole 52, and the cooperation between the positioning hole 52 and the positioning rod 51 can prevent the lower pressure body 31 from deviating from the center of the installation groove 211 due to the elastic force of the elastic member 53, thereby affecting the installation of the test tube, thereby ensuring the stability of the overall structure of the present embodiment.

[0035] The linkage structure 4 includes a first link 41 and a second link 42. The first link 41 is fixedly connected to the lower pressure body 31, and a linkage portion is provided on the first link 41. A direction-changing groove 411 is provided on the linkage portion to prevent the existence of the direction-changing groove 411 from damaging the strength of the first link 41 itself, thereby ensuring the stability of the overall structure of the linkage structure 4. The direction-changing groove 411 is obliquely provided on the linkage portion, and an end of the direction-changing groove 411 close to the clamping body 32 is higher than an end of the direction-changing groove 411 away from the clamping body 32. A linkage block 421 is provided on the second link 42, and the linkage block 421 is located in the direction-changing groove 411, and the linkage block 421 is slidably connected to the direction-changing groove 411. A linkage block 421 is provided on the second link 42, and the linkage block 421 is located in the direction-changing groove 411, and the linkage block 421 is slidably connected to the direction-changing groove 411. The second link 42 is slidably connected to the frame 21.

[0036] With this structural design, when the lower pressure body 31 is forced to slide down, the first connecting rod 41 will be driven to slide down together, and the first connecting rod 41 and the second connecting rod 42 are connected to each other by means of the redirecting groove 411 and the linkage block 421. The second connecting rod 42 should also slide down together, but because the second connecting rod 42 is slidably connected to the frame 21, that is, the second connecting rod 42 is constrained by the frame 21 and cannot move. Therefore, during the sliding of the first connecting rod 41, the force generated by the sliding will mainly act on the linkage block 421 slidably connected to the redirecting groove 411, driving the linkage block 421 to move in the redirecting groove 411, thereby driving the second connecting rod 42 to move in the direction of the mounting groove 211, and the clamping body 32 is fixedly connected to one end of the second connecting rod 42 close to the mounting groove 211. The movement of the second connecting rod 42 in the direction of the mounting groove 211 means that the clamping body 32 moves toward the mounting groove 211. If a test tube is installed in the mounting groove 211, the test tube will be clamped.

[0037] That is, the linkage structure 4 in this embodiment realizes the linkage between the lower pressure body 31 and the clamping body 32 through the connecting rod structure. Compared with other linkage structures, the overall structure of the connecting rod structure is relatively simple, which facilitates the later maintenance and repair of the linkage structure 4. It only needs to ensure the lubrication degree of each connecting part to ensure that the linkage structure 4 can work for a long time and has high stability and reliability.

[0038] At the same time, the distance between the first connecting rod 41 and the center position of the lower pressure body 31 should be greater than or equal to the same distance as the stroke length of the second connecting rod 42, thereby ensuring the movement requirement of the second connecting rod 42 and preventing the second connecting rod 42 from interfering with other parts during the movement. Therefore, a connecting rod 311 is provided between the lower pressure body 31 and the first connecting rod 41, and the connecting rod 311 is fixedly connected to the lower pressure body 31, and the first connecting rod 41 is fixedly connected to the connecting rod 311. In this way, the distance between the first connecting rod 41 and the center position of the lower pressure body 31 is ensured, and the volume of the lower pressure body 31 is reduced as much as possible, so that the staff can drive the lower pressure body 31 to move by installing a test tube. If necessary, a certain force can be given to the lower pressure body 31 again with the help of the test tube to drive the lower pressure body 31 to move.

[0039] A plurality of auxiliary frames 212 are provided on the frame body 21, and each auxiliary frame 212 is fixedly connected to the frame body 21. A sliding opening 2121 is provided on the auxiliary frame 212 for the second connecting rod 42 to be slidably connected, that is, the second connecting rod 42 is constrained by the auxiliary frame 212 rather than the frame body 21. Therefore, even if the second connecting rod 42 is small in size, it can be at different horizontal heights. When the clamping structure 3 clamps the test tube, it cooperates with the accommodating and constraining effect of the mounting groove 211 on the test tube, and clamps the test tube in multiple places, thereby improving the clamping effect of the clamping structure 3. In addition, after the volume of the second connecting rod 42 is reduced, it is also convenient for the first connecting rod 41 to drive the second connecting rod 42 to move.

[0040] At the same time, in order to keep the clamping body 32 in the state of clamping the test tube, Figures 4 to 7 As shown, in this embodiment, a fixing assembly 6 is provided between the second connecting rod 42 and the frame 21 to prevent the lower pressure body 31 from being affected by the reset structure 5 and being reset during the clamping process (when the test tube still needs to be clamped), thereby affecting the normal use of the clamping structure 3.

[0041] The fixing assembly 6 in this embodiment includes a fixing member 61, a fixing groove 62, and a fixing hole 63. The fixing groove 62 penetrates the end of the auxiliary frame 212 away from the frame body 21, and the fixing hole 63 is opened at the end of the second connecting rod 42 close to the fixing groove 62. The fixing member 61 abuts against the fixing hole 63 and is slidably connected with the fixing groove 62. That is, when the fixing member 61 slides to the corresponding position in the fixing groove 62, it abuts against the fixing hole 63. With the help of the fixing hole 63 and the fixing groove 62, the fixing member 61 is constrained at the same time, so that the second connecting rod 42 cannot move, completing the second connecting rod 42. 42 has a fixing effect, so that the clamping body 32 always maintains the state of clamping the test tube, ensuring the stability of the overall structure of this embodiment; and when the fixed state needs to be cancelled, each fixing member 61 can be taken out from each fixing groove 62 in turn. At the same time, in order to facilitate the removal of each fixing member 61, one end of each fixing member 61 away from the fixing hole 63 should be provided with a grasping portion for facilitating the staff to take the fixing member 61, that is, the fixing member 61 in this embodiment can be divided into a grasping portion and a fixing portion according to its effect, so that the fixing member 61 can carry out specific work in this embodiment.

[0042] The fixing member 61 is in a right-angled trapezoidal structure on the vertical projection plane, and the end of the fixing member 61 away from the installation groove is the upper bottom of the fixing member 61. Due to the matching relationship between the fixing member 61 and the fixing hole 63, the fixing hole 63 is in a triangular structure on the vertical projection plane. When the fixing member 61 is completely abutted against the fixing hole 63 under the influence of gravity, the fixing constraint of the fixing member 61 on the second connecting rod 42 is unidirectional, so that the second connecting rod 42 has a relatively high degree of freedom in other directions except for the constraint in a specific direction, which fully guarantees the flexibility of the second connecting rod 42 in this embodiment.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
