[0002] As an important part of modern biotechnology, tissue culture technology plays a key role in plant breeding, seedling rapid propagation, genetic engineering and other fields. In tissue culture test, sample observation is an important link to obtain test data and judge test progress. Super-clean bench is a key equipment for aseptic operation and sample observation. Super-clean bench is usually equipped with a magnifying glass to improve observation accuracy and efficiency.

[0003] Existing magnifying glasses often rely on manual adjustment of the angle and position of the magnifying glass, increasing the complexity and time cost of operation. For situations requiring frequent switching of magnification or simultaneous observation of multiple samples, manual adjustment is particularly inconvenient. The magnifying glass and its bracket can hinder the operation of the experimenter during sample processing. For example, when adding reagents or adjusting the position of the sample, the presence of the magnifying glass can limit the space, increasing the difficulty and risk of operation. If the magnifying glass is moved to one side, the position of the magnifying glass needs to be adjusted again later.

[0004] Therefore, we provide a super-clean bench for tissue culture test to solve the above problems. SUMMARY

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] To address the inconvenience of adjusting existing workbenches for situations requiring frequent magnification switching or simultaneous observation of multiple samples, please refer to [link to relevant documentation]. Figures 1-2 , Figures 4-5 This utility model provides a clean bench for tissue culture experiments, including a bench body 4. An adjusting arm 1 is fixedly mounted on the bench body 4. A ball joint 2 is located at the end of the adjusting arm 1, and a mounting frame 3 is mounted on the ball joint 2. The adjusting arm 1 and the ball joint 2 cooperate to provide the mounting frame 3 with flexible multi-angle adjustment capabilities, allowing experimenters to adjust the mounting frame 3 to a suitable position according to their operating habits and observation needs. A conveying assembly 5 is provided inside the mounting frame 3, and multiple equally spaced magnifying components 6 are provided on the conveying assembly 5. The conveying assembly 5 is used to transport the corresponding magnifying components... The large component 6 is switched to be above the test sample to observe a single test sample or simultaneously compare multiple test samples through the magnification of the component 6 at different magnifications. The magnification component 6 includes a mounting base 601, a magnifying glass holder 602, and a magnifying glass body 603 that is magnetically attached to the magnifying glass holder 602. The magnifying glass holder 602 is rotatably connected to the mounting base 601 to switch between an upright and a flat position. The magnifying glass holder 602 remains upright when not in use and is adjusted to a flat position when observing test samples. The mounting frame 3, the conveying component 5, and the magnification component 6 are all made of lightweight materials, such as aluminum alloy, engineering plastics, or carbon fiber, to reduce the overall weight of the device.

[0030] Special note, such as Figure 1 As shown, the body 4 of the clean bench for tissue culture experiments is surrounded by sealed transparent glass. At least two pairs of sealed glove stations are provided on the front glass to ensure aseptic operation of the workbench. All operations involving the body 4 are performed using sealed gloves. The clean bench also involves other structures, such as ventilation devices. These are not improvements and are not within the scope of protection, so they are not shown in the figure.

[0031] The magnifying glass holder 602 includes a cylindrical body and a rotating body. The rotating body is provided with a rotating shaft, and a torsion spring 602c is sleeved on the rotating shaft. The cylindrical body is provided with a ring platform 602a for supporting the magnifying glass body 603. A plurality of first magnetic pieces 602b are fixedly provided on the ring platform 602a. A plurality of second magnetic pieces 603a that are attracted to the first magnetic pieces 602b are provided at the bottom of the magnifying glass body 603.

[0032] The display glass panel of the platform 4 is provided with a magnetic ring 401 that attracts the second magnetic sheet 603a to fix the magnifying glass body 603 taken out from the magnifying glass holder 602.

[0033] like Figure 3 As shown, the conveying assembly 5 includes two pulleys 501, a conveyor belt 502 wound around the two pulleys 501, and a motor 503 for driving one of the pulleys 501 to rotate. The pulley 501 is rotatably mounted inside the mounting frame 3, and the motor 503 is fixed to the top of the mounting frame 3. The top of the mounting frame 3 is also provided with a switch 504 for controlling the operation of the motor 503. The motor 503 can be a stepper motor to ensure accurate positioning of the amplification assembly 6.

[0034] In use, the magnifying glass body 603, which is fixedly attached to the glass panel of the display case 4, is removed and placed inside the magnifying glass holder 602. By adjusting the arm 1 and the ball joint 2, the mounting bracket 3 is adjusted to a suitable spatial position. At this time, the test sample can be observed through the magnifying glass body 603. Different magnifying components 6 are switched to be directly above the test sample through the conveying component 5, so as to achieve detailed observation of a single test sample at different magnifications. When observing multiple sets of test samples, multiple magnifying components 6 are conveyed to be directly above the test samples, so as to achieve simultaneous comparative observation of multiple sets of test samples, which greatly improves the observation efficiency and accuracy.

[0035] When a sample needs to be processed after observation, the magnifying glass body 603 can be moved to the side of the sample, completely eliminating its spatial obstruction to sample processing operations. When performing delicate operations such as sample cutting, inoculation, and reagent addition, the experimenter does not need to worry about collisions with the magnifying glass body 603 or interference from its position, and can complete various processing steps more freely and efficiently, significantly improving sample processing efficiency. After the processing operation is completed, the magnifying glass body 603 can quickly and accurately return to the top of the sample, reducing observation interruption time and helping the experimenter to capture the immediate changes after sample processing. At the same time, the precise reset movement ensures the consistency of the observation angle and magnification, avoiding observation errors caused by readjusting the position of the magnifying glass body 603, and ensuring the continuity and accuracy of observation data.

[0036] When not in use, the magnifying glass body 603 can be removed from the magnifying glass holder 602 and reattached to the glass panel of the display stand 4. The mounting bracket 3 can also be stored in the glass panel of the display stand 4 to avoid affecting the normal use of the display stand 4.

[0037] Example 2

[0038] Based on Embodiment 1, to facilitate the adjustment of the magnifying glass holder 602 from a vertical position to a horizontal position, such as... Figures 4-5As shown, the mounting base 601 has a flipping member 604 on its side for driving the magnifying glass holder 602 to rotate, and the mounting bracket 3 has a driving member 7 on its top that matches the flipping member 604; the flipping member 604 drives the magnifying glass holder 602 from an upright state to a flat state by means of the translation of the conveying assembly 5.

[0039] The flipping component 604 includes a bevel gearbox 604a fixed on the side of the mounting base 601, a first gear 604b and a second gear 604c fixed on the output shaft and input shaft of the bevel gearbox 604a, and the first gear 604b is fixed coaxially with the rotating shaft of the rotating body; the driving component 7 includes a rotating rod 701 and a rack 702 fixed at the end of the rotating rod 701, and the rack 702 meshes with the second gear 604c.

[0040] The driving component 7 also includes a fixed base 703 fixed to the top of the mounting frame 3, and one end of the rotating rod 701 is rotatably connected to the fixed base 703. Multiple driving components 7 are provided and are evenly distributed on the top of the mounting frame 3. When not in use, they can be adjusted to a vertical state. Based on actual needs, the driving component 7 at the corresponding position can be adjusted to a flat state so that the magnifying component 6 moved to that position can be adjusted to a flat state.

[0041] The magnifying glass mount 602 is initially in an upright position. When it is necessary to observe the test sample, the conveying component 5 drives the mounting base 601 of the corresponding magnifying component 6 to move horizontally. When the flipping part 604 of the magnifying component 6 comes into contact with the driving part 7 during the movement, the second gear 604c and the rack 702 begin to mesh. Since the rack 702 is fixed, the second gear 604c is forced to rotate, and then the rotational motion is transmitted to the first gear 604b through the bevel gear box 604a. The first gear 604b is coaxially fixed with the rotating shaft of the magnifying glass mount 602, so it drives the magnifying glass mount 602 to flip from the upright position to the flat position for observation of the test sample. After the observation is completed, the magnifying glass mount 602 returns to the upright position under the action of the torsion spring 602c.

[0042] The ability to switch between an upright and a flat position for the magnifying glass holder 602 ensures that when not in use, the upright position of the magnifying glass holder 602 will not affect the operation and observation of the adjacent flat position. Furthermore, by utilizing the kinetic energy of the conveying component 5, the magnifying glass holder 602 can be automatically flipped, improving work efficiency.

[0043] Example 3

[0044] Based on Examples 1 and 2, in order to improve the accuracy of sample observation in tissue culture experiments and to improve the ease of closing the 602f supplemental light, such as... Figures 5-6As shown, the bottom of the cylindrical body is provided with multiple supplementary lights 602f evenly distributed along the circumference, and the top of the rotating body is provided with a battery box 602e for supplying power to the supplementary lights 602f; the inner wall of the mounting base 601 is provided with a first metal contact 601a, and the side of the rotating body is provided with a second metal contact 602d that matches the first metal contact 601a. ​​When the rotating body is rotated to a flat position, the first metal contact 601a and the second metal contact 602d are connected to turn on the circuit of the supplementary lights 602f.

[0045] When the magnifying glass mount 602 is in an upright position, the first metal contact 601a and the second metal contact 602d are not in contact, the circuit of the supplementary light 602f is disconnected, and the battery in the battery box 602e is ready to power the supplementary light 602f but is not yet powered. When the conveying component 5 moves the magnifying component 6 to the target position and the driving component 7 flips the magnifying glass mount 602 to a flat position, the first metal contact 601a on the inner wall of the mounting base 601 engages with the second metal contact 602d on the side of the magnifying glass mount 602, closing the circuit of the supplementary light 602f. After observation is completed, the magnifying glass mount 602... 2. When flipped back to the upright position, the first metal contact 601a and the second metal contact 602d separate, and the circuit of the supplementary light 602f is disconnected again, stopping the power supply. The supplementary light 602f, which is evenly distributed along the circumference, can provide all-round, shadowless illumination, significantly improving the quality and accuracy of sample observation. The design of the mechanical contact realizes the automatic connection and disconnection of the circuit, eliminating the need to manually close the supplementary light 602f, simplifying the operation process and improving work efficiency. The supplementary light 602f is only activated when the magnifying glass holder 602 is in a flat position for observation, avoiding unnecessary energy consumption and extending battery life.

[0046] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
