Technical Field

[0001] The utility model relates to the technical field of chemical instruments, in particular to a high-sealing spiral integrated aseptic liquid transfer device. Background Art

[0002] A liquid transfer device, also known as a pipette, is a common chemical instrument. It is a measuring tool for transferring liquid from an original container to another container. It is generally used as a device for weighing and transferring a certain amount of liquid.

[0003] After the existing pipette extracts the medicine, its liquid extraction port is connected to the chamber storing the medicine, and the liquid extraction port is exposed to the outside world, so the extracted medicine may come into contact with the outside air. If it is contaminated by impurities in the air, the medicine will be scrapped. There is room for improvement. Utility Model Content

[0004] The utility model aims to provide a high-sealing spiral integrated aseptic liquid transfer device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highly sealed spiral integrated sterile liquid transfer device, including a liquid storage tube, characterized in that: the liquid collection port of the liquid storage tube is equipped with a closing component, the closing component includes a mounting sleeve mounted on the outside of the liquid collection port of the liquid storage tube, a thread groove is provided on the circumferential inner wall of the mounting sleeve, and a thread line matching the thread groove is provided on the circumferential outer wall of the liquid collection port, a mounting ring is fixedly connected to the bottom of the circumferential inner wall of the mounting sleeve, a closing block is provided on the inner walls on both sides of the mounting ring, and the two closing blocks are arranged to overlap each other.

[0006] As a further preferred embodiment of the present technical solution, a rubber ring is placed on the inner wall of the bottom of the installation sleeve, and the rubber ring is matched with the liquid extraction port of the liquid storage tube.

[0007] After extracting the medicine once, the liquid taking port of the liquid storage tube can be closed to ensure that the medicine therein will not be affected by the external environment, which is beneficial to ensure the purity of the medicine. After the liquid is taken out, the flipped closing block will return to its original state without being subjected to external force, and the two closing blocks will overlap each other again, thereby forming a protection between the medicine and the external space to avoid contact between the medicine and the external space. In addition, the installation sleeve can be removed because it is connected by a threaded groove, ensuring that the cleaning process is more convenient.

[0008] As a further preferred embodiment of the present technical solution, a mounting tube is provided on the top of the liquid storage tube, and an extraction component is installed inside the mounting tube.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in the present embodiment, a highly sealed spiral integrated aseptic liquid transfer device comprises a liquid storage tube 1, characterized in that: a closing component 5 is installed at the liquid taking port of the liquid storage tube 1, the closing component 5 comprises a mounting sleeve 501 which is sleeved on the outside of the liquid taking port of the liquid storage tube 1, a thread groove 504 is provided on the circumferential inner wall of the mounting sleeve 501, and a thread line matching the thread groove 504 is provided on the circumferential outer wall of the liquid taking port, a mounting ring 502 is fixedly connected to the bottom of the circumferential inner wall of the mounting sleeve 501, and a closing block 503 is provided on the inner walls on both sides of the mounting ring 502, and the two closing blocks 503 are arranged to overlap each other.

[0024] A rubber ring 505 is placed on the inner wall of the bottom of the installation sleeve 501 . The rubber ring 505 is matched with the liquid extraction port of the liquid storage tube 1 , and can increase the airtightness between the installation sleeve 501 and the liquid storage tube 1 .

[0025] After the liquid is taken out, the flipped sealing block 503 will return to its original state when no external force is applied, and the two sealing blocks 503 will overlap each other again, thereby forming a protection between the liquid medicine and the external space to prevent the liquid medicine from contacting the external space. In addition, the mounting sleeve 501 can be removed because it is connected by the threaded groove 504, ensuring that the cleaning process is more convenient.

[0026] like Figure 1 and Figure 4 As shown, a mounting tube 2 is provided on the top of the liquid storage tube 1, and an extraction component 6 is installed inside the mounting tube 2.

[0027] The extraction component 6 includes a screw 601 rotatably connected to the inner wall of the bottom of the mounting cylinder 2, the screw 601 is threadedly connected to a piston disk 603, the piston disk 603 is slidably connected in the mounting cylinder 2, and a plurality of limit rods 602 are slidably inserted in the piston disk 603, and the plurality of limit rods 602 are fixedly connected inside the mounting cylinder 2.

[0028] A top cover 3 is sleeved on the outer wall of the top of the installation cylinder 2, and the top cover 3 is coaxially fixed with the screw rod 601. Since the diameter of the top cover 3 is large, it can ensure that the screw rod 601 is driven more easily.

[0029] By moving the top cover 3 to make it rotate on the top of the installation tube 2, the top cover 3 will drive the screw 601 to rotate, and the piston disk 603, which is restricted from rotating by multiple limit rods 602, will be driven by the screw 601 to translate upward, and the liquid storage tube 1 will generate negative pressure, causing the sealing block 503 to flip inward and start to extract the liquid medicine. The movement of the piston disk 603 is achieved by the screw 601, which can ensure that the amount of liquid taken is more accurate.

[0030] like Figure 4 As shown, a reinforcement ring 604 is fixedly connected to the inner wall of the circumferential outer wall of the mounting cylinder 2, and one end of the top of the screw 601 is rotatably connected to the inside of the reinforcement ring 604, so that the state of the screw 601 is more stable, ensuring that the operation process is smooth enough.

[0031] like Figure 1 As shown, the inner wall of the liquid storage tube 1 is provided with scale lines 4, and the scale lines 4 are arranged vertically.

[0032] The utility model provides a high-sealing spiral integrated aseptic liquid transfer device, the specific working principle of which is as follows:

[0033] When the device is working, it is only necessary to hold the installation tube 2, and then rotate the top cover 3 on the top of the installation tube 2, and the top cover 3 will drive the screw 601 to rotate, and the piston disk 603, which is restricted from rotating by multiple limit rods 602, will be driven by the screw 601 to translate upward, and the liquid storage tube 1 will generate negative pressure, so that the sealing block 503 will flip inward to start extracting the medicine. The movement of the piston disk 603 is achieved by the screw 601, which can ensure that the amount of liquid taken is more accurate. After the liquid is taken, the flipped sealing block 503 will no longer be affected by external force and will return to its original state. The two sealing blocks 503 overlap each other again, thereby forming a protection between the medicine and the external space to avoid contact between the medicine and the external space. In addition, the installation sleeve 501 is connected by the threaded groove 504, so it can be removed, ensuring that its cleaning process is more convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
