Description

Technical Field

[0001] This utility model relates to a sample storage device, and more particularly to a biological sample storage device applied in the field of biological sample storage technology. Background Technology

[0002] Biological samples typically refer to plant flowers, leaves, stems, roots, seeds, etc., and animal samples include human body fluids such as urine, blood, saliva, bile, gastric juice, lymph, and other secretions of organisms, as well as hair, muscles, and some tissues and organs such as thymus, pancreas, liver, lungs, brain, stomach, kidneys, etc., and various microorganisms. Currently, storage devices are often used in the market to store biological samples.

[0003] Chinese patent CN218752230U discloses a cryogenic storage device for biological sample testing. When in use, the device uses a lead screw to drive the device and a V-shaped connection between the support disc and the moving blocks on both sides to move the entire support rod and the test tubes placed on it out of the internal area of ​​the refrigerator. With the rotation of the placement disc, it is convenient for the experimenter to find and retrieve the sample test tubes and to place them.

[0004] Existing biological sample storage devices generally lack the ability to clamp and limit the position of sample tubes, resulting in strong shaking during transportation and making it easy for sample tubes to shift or shake. Utility Model Content

[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that biological sample storage devices in the prior art generally do not have the energy to clamp and limit the sample tubes, and the shaking is relatively strong during transportation, which can easily cause the sample tubes to shift and shake.

[0006] To address the aforementioned problems, this utility model provides a biological sample storage device, including a storage box. A sealing cap is detachably connected to the top of the storage box via a latch. A vibration-damping pad is fixedly connected to the bottom of the storage box. Telescopic rods are fixedly connected to the four corners of the top of the vibration-damping pad. A tray is detachably connected to the top of the telescopic rods. The tray has through holes corresponding to the telescopic rods, through which the telescopic rods pass. A nut is connected to the movable end of the telescopic rod above the tray. A vibration-damping spring is fitted onto the surface of the telescopic rod between the vibration-damping pad and the tray. A test tube rack with reagent tubes inserted is placed on the top of the tray. A set of second compression springs is symmetrically fixedly connected to the inner wall of the storage box. A clamp is fixedly connected to the end of the second compression spring away from the inner wall of the storage box, and the clamp abuts against the side of the test tube rack.

[0007] In the aforementioned storage device, by setting a telescopic rod and a vibration damping spring, the reagent tubes placed on the tray can be buffered and vibration damped. Furthermore, by adjusting the up and down of the tray to change the extension and contraction of the vibration damping spring, the vibration damping effect can be adjusted.

[0008] As a further improvement of this application, the top of the pallet is symmetrically provided with grooves, and the bottom of the clamp is slidably connected to the grooves by a slider.

[0009] As a further improvement to this application, a first compression spring is symmetrically fixedly connected between the slide sidewall and the slider, and the clamping plate is designed with multiple sizes.

[0010] As a further improvement of this application, the movable end surface of the telescopic rod is threaded, and the nut is threadedly connected to the movable end of the telescopic rod.

[0011] As another improvement of this application, a handle is fixedly connected to the top of the sealing cap, and retractable and adjustable shoulder straps are connected to both ends of the storage box.

[0012] As a further improvement to this application, a transparent card box is fixedly connected to the front of the storage box, and a label is inserted inside the card box.

[0013] In summary, after the reagent tubes are inserted into the test tube rack and positioned, the test tube rack is placed on the tray at the bottom of the storage box. The tray is automatically clamped by two clamps on the inner wall of the storage box through a second compression spring, thus positioning the test tube rack on the tray. During the handling of the storage box, any shaking can be buffered and damped by the telescopic rod and the vibration damping spring. The clamps are movable, so they do not affect the purpose of vibration damping. The tray can be moved up and down on the telescopic rod and fixed by the threaded nut, thereby adjusting the extension and retraction of the vibration damping spring and changing the vibration damping effect.

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figures 1-4 and Figure 6 A biological sample storage device is shown, including a storage box 1. A sealing cover 3 is detachably connected to the top of the storage box 1 via a latch 4. A vibration damping pad 7 is fixedly connected to the bottom of the storage box 1. Telescopic rods 8 are fixedly connected to the four corners of the top of the vibration damping pad 7. A tray 19 is detachably connected to the top of the telescopic rod 8. A through hole corresponding to the telescopic rod 8 is opened on the tray 19, and the telescopic rod 8 passes through the through hole. A nut 10 is connected to the movable end of the telescopic rod 8 above the tray 19. A vibration damping spring 9 is sleeved on the surface of the telescopic rod 8 between the vibration damping pad 7 and the tray 19. A test tube rack 15 with reagent tubes 16 inserted is placed on the top of the tray 19. A set of second compression springs 14 are symmetrically fixedly connected to the inner wall of the storage box 1. A clamp 13 is fixedly connected to the end of the second compression spring 14 away from the inner wall of the storage box 1, and the clamp 13 abuts against the side end of the test tube rack 15.

[0025] The movable end of the telescopic rod 8 has a threaded design, and the nut 10 is threadedly connected to the movable end of the telescopic rod 8.

[0026] Working principle: After the reagent tube 16 is inserted into the test tube rack 15 for positioning, the test tube rack 15 is placed on the tray 19 at the bottom of the storage box 1. The tray 19 is automatically clamped by the two clamps 13 on the inner wall of the storage box 1 through the second compression spring 14, thereby positioning the test tube rack 15 on the tray 19. During the transportation of the storage box 1, if shaking occurs, the reagent tube 16 on the test tube rack 15 can be buffered and damped by the telescopic rod 8 and the damping spring 9. The clamps 13 and the test tube rack 15 are movable ends, so they do not affect the purpose of damping. The tray 19 can be moved up and down on the telescopic rod 8 and is fixed by the threaded nut 10, thereby adjusting the extension and retraction of the damping spring 9, adjusting the spring force, and changing the damping effect.

[0027] By setting the telescopic rod 8 and the damping spring 9, the reagent tube 16 placed on the tray 19 can be buffered and damped. The extension and contraction of the damping spring 9 can be changed by adjusting the tray 19 up and down to achieve the effect of adjusting the damping.

[0028] Second implementation method:

[0029] Figure 1 and Figure 5 The top of the tray 19 is symmetrically provided with a sliding groove 11, and the bottom of the clamp 13 is slidably connected to the sliding groove 11 via a slider 17. A first compression spring 12 is symmetrically fixed between the side wall of the sliding groove 11 and the slider 17. The clamp 13 is designed in multiple sizes. The top of the sealing cover 3 is fixedly connected with a handle 18. The two ends of the storage box 1 are connected with retractable and adjustable shoulder straps 2. The front end of the storage box 1 is fixedly connected with a transparent card box 5, and a label 6 is inserted into the card box 5.

[0030] Working principle: When multiple test tube racks 15 are placed, they can be stacked on the tray 19. At this time, the clamping plate 13 slides and adjusts in the slide groove 11 through the first compression spring 12 and the slider 17 to clamp the test tube rack 15. With the help of the second compression spring 14, the positioning effect can be improved, and the instability caused by the excessive height of the stacked test tube racks 15 can be avoided. After storing the same batch of reagent tubes 16 in the storage box 1, the information label 6 of the batch containing biological samples can be inserted into the card box 5 to facilitate information identification during transportation. During transportation, it can be easily transported by carrying it on the shoulder with the shoulder strap 2.

[0031] By setting the first compression spring 12 and the slide 11, the stacked test tube racks 15 can be reinforced, and a card box 5 is set on the storage box 1. The corresponding information tag 6 can be inserted into the card box 5 according to the biological sample stored, which is convenient for identification.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
