[0002] When performing derivatization measurements in the laboratory, centrifuge tubes need to be placed in an ice-water bath. Currently, the testing industry commonly uses storage baskets with ice packs for derivatization, but the temperature of the ice-water bath is uncontrollable, affecting the accuracy of the data. Therefore, a water bath thermostat is needed to hold the centrifuge tubes in an ice-water bath. Centrifuge tubes are usually placed on tube racks inside the water bath, but most existing tube racks cannot accommodate centrifuge tubes of different sizes. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a centrifuge tube water bath constant temperature device, so that the tube rack in the water bath can adapt to centrifuge tubes of different specifications.

[0005] Furthermore, the tube rack has two layers of clamping plates, namely an upper clamping plate and a lower clamping plate; the lower clamping plate has a sliding groove, and the upper clamping plate is connected to a slider, which is inserted into the sliding groove so that the upper clamping plate can slide along the sliding groove.

[0006] Furthermore, the tube placement holes on the upper and lower plates are both square holes, and the length direction of the sliding groove is consistent with the diagonal direction of the tube placement hole.

[0007] Furthermore, a locking mechanism is provided on the lower card plate, which can lock and fix the positions of the upper card plate and the lower card plate.

[0008] Furthermore, the locking mechanism includes locking bolts disposed at the end of the sliding groove, and one locking bolt on each side of the upper plate at opposite corners. The two locking bolts can cooperate to abut against the upper plate to lock the position of the upper plate.

[0009] Furthermore, the water bath contains an oscillating basket, and the device body contains an oscillation mechanism that drives the oscillating basket to move; a support foot is provided below the lower plate, and the lower plate can be placed in the oscillating basket by means of the support foot.

Attached Figure Description

[0012] Appendix Figure 1 A schematic diagram of the overall structure of the water bath constant temperature device;

[0013] Appendix Figure 2 This is a schematic diagram of the pipe rack structure. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As attached Figures 1 to 2 The centrifuge tube water bath constant temperature device includes a device body 1, a water bath tank 2 on the device body 1, and a tube rack 3 for placing centrifuge tubes in the water bath tank 2.

[0016] The tube rack 3 includes at least two layers of clamping plates, each with several tube insertion holes 4. Taking the two-layer clamping plates as an example, the tube insertion holes 4 on the two layers of clamping plates are vertically opposite each other. When centrifuge tubes are placed on the tube rack 3, the centrifuge tubes are inserted into the tube insertion holes 4 of each layer of clamping plates in sequence. The clamping plates of different layers can move relative to each other, changing the relative area of ​​the tube insertion holes 4 of each layer, thereby clamping the centrifuge tubes to accommodate centrifuge tubes of different specifications. Thus, through the design of multiple clamping plates, the tube rack 3 of this utility model can adapt to centrifuge tubes of different specifications, improving the versatility of the tube rack 3.

[0017] As attached Figure 2 In one embodiment, two layers of clamping plates are provided on the pipe rack 3, namely an upper clamping plate 5 and a lower clamping plate 6. A sliding groove 7 is provided on the lower clamping plate 6, and a slider 8 is connected to the upper clamping plate 5, with the slider 8 correspondingly inserted into the sliding groove 7, so that the upper clamping plate 5 can slide along the sliding groove 7 on the upper clamping plate 5, thereby changing the relative area of ​​the pipe placement hole 4 on the upper clamping plate 5 and the lower clamping plate 6.

[0018] Specifically, the tube insertion holes 4 on the upper clamping plate 5 and the lower clamping plate 6 are both square holes. The intersection area of ​​the tube insertion holes 4 on the upper clamping plate 5 and the lower clamping plate 6 will also form a square hole. The tube insertion hole 4 can be inserted into the intersection area of ​​the tube insertion holes 4 on the upper clamping plate 5 and the lower clamping plate 6. The boundary of the intersection area limits the centrifuge tube, thereby clamping the centrifuge tube and preventing the centrifuge tube from shaking in the tube insertion hole 4 during the operation of the water bath constant temperature device.

[0019] Both the upper clamping plate 5 and the lower clamping plate 6 have square holes, and the intersecting area of ​​the upper clamping plate 5 and the lower clamping plate 6 is also a square hole. Since the cross-section of the centrifuge tube is circular, the four sides of the square holes can limit the centrifuge tube, so the clamping effect of the tube rack 3 on the centrifuge tube is better. The length direction of the sliding groove 7 is consistent with the diagonal direction of the tube placement hole 4, so the intersecting area of ​​the upper clamping plate 5 and the lower clamping plate 6 can remain square during the movement of the upper clamping plate 5.

[0020] The lower clamping plate 6 is provided with a locking mechanism, which can lock and fix the positions of the upper clamping plate 5 and the lower clamping plate 6, so that the upper clamping plate 5 and the lower clamping plate 6 cooperate to clamp the centrifuge tube.

[0021] As attached Figure 2 In the illustrated embodiment, there is a sliding groove 7 at each diagonal end of the upper clamping plate 5. The locking mechanism includes a locking bolt 9 disposed at the end of the sliding groove 7. A threaded hole is provided on the inner wall of the sliding groove 7, and the locking bolt 9 is installed in the threaded hole, so that one end of the locking bolt 9 extends into the sliding groove 7. There is a locking bolt 9 at each diagonal end of the upper clamping plate 5, so the locking bolts 9 in the two sliding grooves 7 can be diagonally opposed to the upper clamping plate 5 from both ends, thereby fixing the position of the upper clamping plate 5.

[0022] The water bath 2 contains a vibrating basket 10, and the device body 1 contains a vibrating mechanism that drives the vibrating basket 10 to move. A support leg 11 is provided below the lower clamping plate 6, and the lower clamping plate 6 can be placed in the vibrating basket 10 through the support leg 11. When the vibrating basket 10 vibrates, it also drives the centrifuge tubes on the tube rack 3 to vibrate, so that the material in the centrifuge tubes can be cooled more evenly by the ice water bath.

[0023] The device body 1 is equipped with a compressor, which can dissipate heat from the liquid in the water bath 2 and maintain the liquid temperature in the water bath 2 to achieve a constant temperature function.

[0024] When placing the centrifuge tubes on the tube rack 3, first loosen the locking bolt 9, then insert the centrifuge tubes into the tube placement holes 4 of the upper and lower clamping plates, and then tighten the locking bolt 9 so that the upper and lower clamping plates can secure the centrifuge tubes. When the water bath constant temperature device is working, add ice water to the water bath 2, place the tube rack 3 with the centrifuge tubes inserted into the shaking basket 10, and the shaking mechanism and compressor work to achieve shaking and temperature control.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
