Description

Technical Field

[0001] The utility model relates to the technical field of temperature control boxes, in particular to a temperature control box for extracting and purifying reagents. Background Art

[0002] The extraction and purification of reagents generally refers to the process of separating and obtaining target compounds from complex mixtures. This process is very common in the fields of chemistry, biochemistry, drug research and development, etc. Common methods include solvent extraction, column chromatography, gel filtration, centrifugal separation, etc.; During the process of extracting and purifying reagents, a temperature control box is required to store the extraction test tubes at a constant temperature.

[0003] When the temperature control box in real life stores the extraction test tubes at a constant temperature, the extraction test tubes are placed on a test tube rack, and the test tube rack is placed in the compartment of the temperature control box. When it is necessary to store or take out the extraction test tubes, the entire test tube rack needs to be taken out to facilitate the storage or taking out of the extraction test tubes. After that, the entire test tube rack needs to be put back into the temperature control box again. This method is time-consuming and laborious, and the operation is relatively cumbersome, which is not convenient for quickly storing and taking out the extraction test tubes; Therefore, we propose a temperature control box for extracting and purifying reagents to solve the above problems.

[0009] Preferably, the rotating groove at the bottom side of the lower clamping plate is arranged in an arc-shaped structure, and the depth value of the positioning groove is twice the depth value of the rotating groove. When the two positioning rods are separated from the corresponding positioning grooves, the tops of the two positioning rods are convenient to move in the corresponding rotating grooves, so as to limit the rotation of the two lower clamping plates.

[0010] Preferably, the plugging elastic mechanism includes a circular frame and a spring. The circular frame is movably installed in the circular frame cover. One end of the spring is fixedly installed on the top side of the circular frame, and the other end of the spring is fixedly installed on the inner wall of the top side of the circular frame cover. The circular frame is fixedly connected with the corresponding two positioning rods. Through the plugging elastic mechanism, the two positioning rods are respectively inserted into the corresponding two positioning grooves, so as to position and fix the positions of the two groups of rotating rods, upper clamping plates and lower clamping plates.

[0011] Preferably, a plurality of circular frame covers are respectively located at the bottom sides of the corresponding reagent tube bodies. There is a gap between the circular frame and the inner wall of the stepped frame, and the depth value of the gap is the same as the depth value from the inner wall of the rotating groove to the inner wall of the positioning groove.

[0014] For the temperature control box for the extraction and purification reagent, the reagent tube body storing the extraction and purification reagent is stored at a constant temperature through the temperature control box body. When the corresponding reagent tube body needs to be taken, by pressing down the corresponding circular frame, the bottom side of the circular frame abuts against the bottom wall of the stepped frame. At this time, the two positioning rods on the circular frame are separated from the corresponding two positioning grooves, and at this time, it is convenient to take out the reagent tube body, with simple, fast, time-saving and labor-saving operation; when the reagent tube body is clamped in the arc-shaped grooves of the corresponding two groups of upper clamping plates and lower clamping plates, the reagent tube body is clamped and fixed, which is convenient for the reagent tube body to be stably placed and stored in the temperature control box body.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-5, A temperature-controlled box for extraction and purification reagents, comprising a temperature-controlled box body 1, a reagent tube body 2 and a reagent tube plug 3. A chamber 4 is arranged inside the temperature-controlled box body 1, and a stepped rack 5 is arranged inside the chamber 4. A plurality of rotating rods 6 are respectively rotatably installed on the inner walls of the stepped rack 5. Upper clamping plates 7 and lower clamping plates 8 are respectively fixedly installed on the plurality of rotating rods 6. The same reagent tube body 2 is inserted between two groups of upper clamping plates 7 and lower clamping plates 8. A reagent tube plug 3 is inserted on the reagent tube body 2. A rotating groove 9 is opened on the bottom side of the lower clamping plate 8, and a positioning groove 10 is opened on the inner wall of the rotating groove 9. A plurality of circular frame covers 11 are fixedly installed on the inner wall of the stepped rack 5. Two positioning rods 14 are installed in the circular frame cover 11 through an insertion elastic mechanism. The insertion elastic mechanism comprises a circular frame 12 and a spring 13. The circular frame 12 is movably installed in the circular frame cover 11. One end of the spring 13 is fixedly installed on the top side of the circular frame 12, and the other end of the spring 13 is fixedly installed on the inner wall of the top side of the circular frame cover 11. The circular frame 12 is fixedly connected with two corresponding positioning rods 14. Through the insertion elastic mechanism, the two positioning rods 14 are respectively inserted into the two corresponding positioning grooves 10 to position and fix the positions of the two groups of rotating rods 6, upper clamping plates 7 and lower clamping plates 8; the top ends of the two positioning rods 14 are respectively inserted into the corresponding positioning grooves 10.

[0023] Specifically, the cross-section of the stepped rack 5 is arranged in a stepped structure. A plurality of steps are arranged on the stepped rack 5, which is convenient for the staff to quickly find the reagent tube body 2 storing the extraction and purification reagents on the stepped rack 5.

[0024] Specifically, the upper clamping plates 7 and lower clamping plates 8 on the rotating rod 6 are both provided with arc-shaped grooves. The reagent tube body 2 is inserted into the arc-shaped grooves of the two corresponding groups of upper clamping plates 7 and lower clamping plates 8. When the reagent tube body 2 is inserted into the arc-shaped grooves of the two corresponding groups of upper clamping plates 7 and lower clamping plates 8, the reagent tube body 2 storing the extraction and purification reagents is limited and stored.

[0025] Specifically, the rotating groove 9 on the bottom side of the lower clamping plate 8 is arranged in an arc-shaped structure. The depth value of the positioning groove 10 is twice the depth value of the rotating groove 9. When the two positioning rods 14 are separated from the corresponding positioning grooves 10, it is convenient for the top ends of the two positioning rods 14 to move in the corresponding rotating groove 9 to limit the rotation of the two lower clamping plates 8.

[0026] Further, the plurality of circular frame covers 11 are respectively located at the bottom sides of the corresponding reagent tube bodies 2. A gap is arranged between the circular frame 12 and the inner wall of the stepped rack 5, and the depth value of the gap is the same as the depth value from the inner wall of the rotating groove 9 to the inner wall of the positioning groove 10. When the circular frame 12 is pressed down to abut against the inner wall of the stepped rack 5, at this time, the two positioning rods 14 are separated from the two corresponding positioning grooves 10.

[0027] Specifically, a box door 15 is provided on one side of the temperature-controlled box body 1, and a glass observation window 16 is provided on the box door 15. Through the glass observation window 16, the situation of the reagent tube body 2 storing and extracting the purified reagent at a constant temperature inside the temperature-controlled box body 1 can be observed in real time.

[0028] During use: The reagent tube body 2 is stored at a constant temperature by the temperature-controlled box body 1. When the corresponding reagent tube body 2 inside the temperature-controlled box body 1 needs to be taken, the staff opens the box door 15. Multiple reagent tube bodies 2 are stored and placed on the step rack 5, which is convenient for the staff to quickly find the reagent tube body 2 to be taken. By pressing the corresponding round frame 12, the spring 13 is deformed and stretched by the force, until the bottom side of the round frame 12 fits against the bottom wall of the step rack 5. At this time, the two positioning rods 14 on the round frame 12 are disengaged from the corresponding two positioning grooves 10. The staff holds the reagent tube body 2 by hand and takes out the reagent tube body 2 outward, so that the reagent tube body 2 drives the two groups of rotating rods 6, the upper clamping plate 7 and the lower clamping plate 8 to rotate, so that the reagent tube body 2 is disengaged from the arc-shaped grooves on the two groups of upper clamping plates 7 and lower clamping plates 8, thus realizing the quick taking of the reagent tube body 2. When the reagent tube body 2 is clamped in the arc-shaped grooves of the corresponding two groups of upper clamping plates 7 and lower clamping plates 8, the clamping and fixing of the reagent tube body 2 are realized, which is convenient for the stable placement and storage of the reagent tube body 2 in the temperature-controlled box body 1.
