Technical Field

[0001] This utility model specifically relates to the field of experimental auxiliary tools for culture media, and more specifically to an auxiliary tube for adding pH adjuster to culture media. Background Technology

[0002] In fields such as microbial culture, cell fermentation, and biopharmaceuticals, the pH value of the culture medium is a key environmental parameter that affects the growth activity of microorganisms, the efficiency of cell metabolism, and the synthesis of target products. It needs to be precisely controlled to a suitable range using pH adjusters. Generally, a dropper is used to draw up the pH adjuster and then add it to the culture medium.

[0003] However, if the traditional pH adjustment agent addition tube is designed as an integrated unit, or if the hollow extraction tube is fixedly connected to the main structure, it needs to be replaced when the hollow extraction tube is damaged due to collision or wear. In addition, the addition tube will come into contact with different types of regulators in the experiment. If it is reused, it will lead to cross-contamination, which will affect the accuracy of the culture medium adjustment. Again, it is necessary to replace the addition tube. This results in the high cost of using traditional addition tubes. Utility Model Content

[0031] The detachable reagent extraction tube 5 has a hollow extraction tube 51, and the top end of the hollow extraction tube 51 is symmetrically provided with an extension mounting plate 53. Each of the extension mounting plates 53 has an open groove 54 at the end away from the hollow extraction tube 51.

[0032] Furthermore, the two open slide grooves 54 are staggered, and the longitudinal interface of the T-shaped locking post 8 is T-shaped. A rubber sleeve is also fixedly connected to the outside of the T-shaped locking post 8, so that the T-shaped locking post 8 and the open slide groove 54 are interference fit through the rubber sleeve.

[0033] By adopting the above technical solution, a clean, removable reagent extraction tube 5 is placed under the hollow handle 2, and the sealing ring 52 is aligned with the bottom of the concave slot 7 for insertion and engagement. Then, the hollow extraction tube 51 is rotated, which drives the extension mounting plates 53 on both sides to rotate until the T-shaped locking pin 8 is engaged in the open sliding groove 54 at the end of the extension mounting plate 53, thus quickly connecting the removable reagent extraction tube 5 and the hollow handle 2. Therefore, it is easy to quickly replace the hollow extraction tube 51 when it is damaged or contaminated by other reagents.

[0034] Furthermore, the inner side of the hollow handle 2 is hollow, and the side of the hollow handle 2 is provided with a through groove 3 that communicates with the inner side. In addition, the inner side of the hollow handle 2 is also slidably fitted with a negative pressure extraction rod 6.

[0035] Furthermore, the negative pressure extraction rod 6 has a sliding connecting rod 61 that passes through the hollow handle 2.

[0036] The movable ring 63 extends through the through groove 3 to the side of the hollow grip 2 on the side away from the connecting cap 62, and the movable ring 63 slides in conjunction with the through groove 3.

[0037] More specifically, the top of the detachable conical head 64 is integrally provided with a threaded connecting rod 66, and the end of the sliding connecting rod 61 is provided with a threaded hole that is threadedly engaged with the threaded connecting rod 66. A rubber sealing sleeve 65 is also fixedly connected to the outside of the detachable conical head 64.

[0038] Furthermore, the end of the sliding link 61 extends to the inner side of the hollow extraction tube 51, and the detachable conical head 64 slides in cooperation with the inner side of the hollow extraction tube 51, while the outer side of the rubber sealing sleeve 65 is in contact with the inner side of the hollow extraction tube 51.

[0039] By adopting the above technical solution, the detachable conical head 64 is rotated, which drives the threaded connecting rod 66 above to rotate. Through the threaded engagement between the threaded connecting rod 66 and the end of the sliding connecting rod 61, the detachable conical head 64 is removed from below the sliding connecting rod 61, thereby disassembling the detachable conical head 64 and facilitating its rapid replacement, thus ensuring the speed of replacement.

[0040] Furthermore, both sides of the bottom of the hollow grip 2 are integrally provided with extension connecting seats 4, and the bottom of each extension connecting seat 4 is integrally set with the T-shaped locking post 8.

The bottom shape of the detachable conical head 64 corresponds to the bottom shape of the hollow extraction tube 51, ensuring that the detachable conical head 64 can fit against the inner bottom of the hollow extraction tube 51 when it slides downward, thereby completely discharging the regulator and preventing residue from remaining inside.

[0044] Furthermore, a reinforcing protrusion 55 is integrally provided at the connection between the hollow extraction tube 51 and the extension mounting plate 53. One end of the opening groove 54 is provided with an opening that extends to the side of the extension mounting plate 53, and the reinforcing protrusion 55 is located on the side away from the opening.

[0045] The working principle of this utility model is as follows: In use, firstly, the detachable conical head 64 is fixedly connected to the lower part of the sliding connecting rod 61 through the threaded connection between the threaded connecting rod 66 and the sliding connecting rod 61. Then, a clean, removable reagent extraction tube 5 is placed below the hollow handle 2, and the sealing ring 52 is aligned with the bottom of the concave slot 7 for insertion. Then, the hollow extraction tube 51 is rotated, causing the extension mounting plates 53 on both sides to rotate until the T-shaped locking pin 8 is engaged in the open sliding groove 54 at the end of the extension mounting plate 53, quickly connecting the removable reagent extraction tube 5 and the hollow handle 2. Simultaneously, the rubber sealing sleeve 65 is inserted into the hollow extraction tube 51. On the side, through the cooperation of the moving ring 63 and the sliding link 61, the rubber sealing sleeve 65 is pushed to the bottom of the inner side of the hollow extraction tube 51.
