[0031] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0032] like Figure 1-3 As shown, a refrigerated centrifugal device that is convenient for taking and placing materials includes:

[0033] A freezing box body 1 is provided with a freezing centrifugal chamber in the freezing box body 1, and an opening is provided on the top of the freezing box body 1 which is connected to the freezing centrifugal chamber;

[0034] The freezing chamber cover 2 is hinged on the freezing chamber body 1 and is suitable for opening or closing the opening at the top of the freezing chamber body 1;

[0035] A centrifugal drive mechanism is installed in the refrigeration box 1 and is provided with a rotating shaft extending into the refrigeration centrifugal chamber;

[0036] A refrigeration assembly is installed in the freezing box 1 and is suitable for refrigerating the refrigerated centrifugal chamber;

[0037] The rotating connecting rod 3 is installed in the refrigerated centrifugal chamber. One end of the rotating connecting rod 3 is connected to the rotating shaft of the centrifugal drive mechanism. The other end is provided with a plurality of rotating transmission grooves at intervals on the circumference, and a limiting hole is provided at the center of rotation.

[0038] A quick-release test tube rack 4 is detachably mounted on the other end of the rotating connecting rod 3. The quick-release test tube rack 4 is provided with a plurality of rotating transmission lugs that cooperate with the rotating transmission grooves, and a limiting pin 41 that cooperates with the limiting hole;

[0039] The quick-release test tube rack 4 is provided with test tube holes suitable for mounting multiple test tubes.

[0040] In this embodiment, if Figure 1-3 As shown, the material is usually a test tube. During use, the quick-release test tube rack 4 is first removed from the rotating connecting rod 3 in the refrigerated centrifuge chamber, and then the test tube is hung on the quick-release test tube rack 4. After completing this step, the quick-release test tube rack 4 containing the test tube is reinstalled on the rotating connecting rod 3. By inserting the limit pin of the quick-release test tube rack 4 into the limit hole of the rotating connecting rod 3, the stability of the quick-release test tube rack 4 during operation can be ensured. Then close the refrigeration chamber cover 2, and the centrifugal drive mechanism cooperates with the rotating transmission groove of the rotating connecting rod 3 and the rotating transmission lug on the quick-release test tube rack 4 to realize the rotation of the quick-release test tube rack 4. After the centrifugation process is completed, the quick-release test tube rack 4 is taken out and the test tube is taken. The whole process greatly improves the convenience of taking and placing test tubes, making it easy to put test tubes and other materials into or out of the refrigerated centrifuge chamber.

[0041] During the centrifugation process, the refrigeration component provides the necessary low temperature environment for the frozen centrifuge chamber, ensuring the temperature stability of the material throughout the centrifugation process.

[0042] Specifically, such as Figure 1-3 As shown, a limit stopper 11 is also provided at the opening of the freezing box body 1;

[0043] The limit stopper 11 is adapted to abut against the freezing chamber cover 2 when the freezing chamber cover 2 is closed.

[0044] In this embodiment, if Figure 1-2 As shown, a stopper 11 is provided on the edge of the opening of the freezer compartment 1. When the freezer compartment cover 2 is closed, the top of the stopper 11 abuts against the bottom of the freezer compartment cover 2, acting as a limiter to prevent the freezer compartment cover 2 from being excessively pressed into the freezer compartment 1. The stopper 11 can be made of a hard material such as metal or plastic to ensure sufficient strength and wear resistance. When the stopper 11 abuts against the freezer compartment cover 2, a sufficient seal is formed to prevent the cold air inside the freezer compartment 1 from leaking out.

[0045] Specifically, such as Figure 1-3 As shown, the refrigerated centrifugal device for convenient material placement also includes a magnetic attraction matching component, which can be a structure as follows, including:

[0046] A magnetic component is mounted on the limit stopper 11;

[0047] The magnetic fitting part 21 is installed on the freezing chamber cover 2 .

[0048] In this embodiment, if Figure 1-3 As shown, magnetic coupling components, including a magnetic assembly and a magnetic coupling member 21, are provided on the stopper 11 and the freezer compartment cover 2, respectively. The magnetic assembly is mounted on the stopper 11, and the magnetic coupling member 21 is mounted on the corresponding freezer compartment cover 2. When the freezer compartment cover 2 is closed, the magnetic assembly and the magnetic coupling member 21 come into close proximity and are magnetically attracted, allowing the freezer compartment cover 2 to securely fit the opening of the freezer compartment 1, enhancing the seal and preventing cold air leakage.

[0049] The magnetic component can be a permanent magnet, and the magnetic matching part 21 can be a metal that can be attracted by a magnet. In some embodiments, the magnetic component can be installed on the freezing chamber cover 2, and the magnetic matching part 21 can be installed on the limit block 11.

[0050] Specifically, such as Figure 1 and Figure 3 As shown, the quick-release test tube rack 4 is further provided with a pulling structure, which may be the following structure, including:

[0051] The pull ring 5 is hinged on the quick-release test tube rack 4.

[0052] In this embodiment, if Figure 1 and Figure 3 As shown, when the test tube needs to be taken out or placed, the quick-release test tube rack 4 can be lifted or lowered as a whole by holding the pull ring 5, which is very convenient to operate.

[0053] Specifically, such as Figure 2-3 As shown, the freezing chamber cover 2 is made of transparent material.

[0054] In this embodiment, if Figure 1-3 As shown, the freezing chamber cover 2 can be made of organic glass, or transparent plastic or the like. Such a design allows for clear observation of the interior of the freezing centrifuge chamber when the freezing chamber cover 2 is closed, facilitating real-time monitoring of the centrifugal process.

[0055] In addition, the transparent material is also beneficial to the lighting inside the freezing box 1, making the internal environment brighter and convenient for operation and observation.

[0056] According to actual needs, the degree of transparency of the freezing chamber cover 2 can be selected to be different, for example, using a translucent or colored transparent material to adapt to different observation and use environments.

[0057] Specifically, such as Figure 2-3 As shown, a handle 6 is also provided on the freezing chamber cover 2.

[0058] In this embodiment, if Figure 2-3 As shown, a handle 6 is provided on the top of the freezing chamber cover 2. The handle 6 can be made of metal or plastic. The provision of the handle 6 allows the operator to conveniently apply force by grasping the handle 6 when opening or closing the freezing chamber cover 2, greatly improving the convenience of opening and closing the cover.

[0059] The handle 6 is in the shape of an elongated strip, and some embodiments may also be designed according to actual needs, such as being in an arc shape, a ring shape, etc.

[0060] Specifically, such as Figure 1 As shown, the refrigerated centrifuge device for convenient material placement also includes a control panel, which includes a display device 61 and two control knobs 62.

[0061] In this embodiment, if Figure 1 As shown, the control panel is used to operate and control the operation of the entire refrigerated centrifuge equipment.

[0062] The display device 61 can be a liquid crystal display, an LED display, or other display element. It is used to display the current operating status of the device, temperature, rotation speed, centrifugation time, and other parameter information. It can also display operation menus and prompts. The size and resolution of the display device 61 should be reasonably designed according to actual conditions to ensure that the parameters displayed are clear and readable.

[0063] The control knob 62 is used to input and adjust various parameters of the device, such as speed, temperature, and centrifugation time. The control knob 62 can be a physical knob or a touch-sensitive knob, providing smooth operation. Depending on actual needs, two control knobs 62 can be designed, each controlling a different parameter. In some embodiments, the number of control knobs 62 is not limited to two and can be adjusted based on specific needs.

[0064] Specifically, such as Figure 1-2 As shown, the refrigeration component is a semiconductor refrigeration plate, and the refrigeration surface of the semiconductor refrigeration plate is in contact with the refrigeration centrifugal cavity of the refrigeration box body 1.

[0065] In this embodiment, if Figure 1-2 As shown, the cooling surface of the semiconductor refrigeration chip is directly attached to the inner wall of the refrigerated centrifugal chamber of the freezer box 1, maximizing refrigeration efficiency and quickly cooling the environment inside the centrifugal chamber to the desired low temperature. The semiconductor refrigeration chip does not require a compressor or refrigerant, and its structure is compact, silent, long-lasting, and environmentally friendly and energy-saving.

[0066] The cooling temperature and cooling capacity of the semiconductor refrigeration chip can be adjusted within a certain range according to actual needs by controlling the magnitude of the supply current. The refrigeration chip itself also has a temperature control protection device to prevent overcooling or overheating.

[0067] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific 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 scope of protection of the present invention.
