DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 2As shown, the utility model provides a portable extraction tube, comprising: an extraction tube body 2 for storing extraction liquid, a piston 7 and a moving mechanism are sequentially installed in the extraction tube body 2 along the axial direction, one end of the moving mechanism extends to the outside of the extraction tube body 2, and a storage bin 16 for negative pressure storage is formed between the end of the extraction tube body 2 away from the moving mechanism and the piston 7, and the moving mechanism is used to adjust the axial length of the piston 7 in the storage bin 16.

[0022] As described above, when using the extraction tube body 2, piston 7 and moving mechanism provided by the utility model, the piston 7 forms a storage bin 16 for storing the extraction liquid inside one end of the extraction tube body 2. The position of the piston 7 in the storage bin 16 can be adjusted by the moving mechanism. When the piston 7 moves toward one side of the moving mechanism, it is convenient to absorb the extraction liquid outside the extraction tube body 2 into the storage bin 16. When the piston 7 is pushed outward, it is convenient to push the extraction liquid out of the storage bin 16.

[0023] In the present utility model, combined with Figure 2 As shown, a needle tube 6 for leading out or leading in the extracting liquid protrudes from one end of the extracting tube body 2 of this embodiment, and one end of the needle tube 6 extends into the storage bin 16 .

[0024] As mentioned above, when using the needle tube 6 provided by the utility model, the needle tube 6 can prevent the extraction liquid from flowing out through the needle tube 6 when the piston 7 in the storage bin 16 is not subjected to force. When the extraction liquid needs to be taken out, the needle tube 6 is directly aimed at the receiving object, which facilitates the extraction liquid to be directly introduced into the receiving object and prevents the extraction liquid from being scattered outside the receiving object.

[0025] Further, in order to protect the needle tube 6, refer to Figure 1-2 As shown, a sealing cap 3 for protecting the needle tube 6 is detachably mounted on one end of the extraction tube body 2, and a rubber cone 5 that can be inserted into the needle tube 6 is disposed on the inner side of the sealing cap 3. When the needle tube 6 is not in use, the sealing cap 3 is used to protect the needle tube 6. During this process, the rubber cone 5 on the sealing cap 3 is pressed and inserted into the needle tube 6, thereby preventing the extraction liquid in the storage bin 16 from overflowing through the needle tube 6.

[0026] Further, in order to detachably mount the sealing cap 3 on the outside of the needle tube 6, refer to Figure 2 As shown, one end of the extraction tube body 2 is provided with an external thread seat 4, the sealing cap 3 is screwed on the external thread seat 4, and one end of the needle tube 6 passes through the external thread seat 4. The external thread seat 4 provides a mounting position for the sealing cap 3 on the extraction tube, so that the sealing cap 3 covers the outside of the needle tube 6.

[0027] In the present utility model, combined with Figure 2-4As shown, the moving mechanism of this embodiment includes a screw rod 14, a connecting sleeve 8 and a guide member, the guide member is used to axially guide the movement of the piston 7, one end of the connecting sleeve 8 is installed at the axis center of one end of the piston 7, one end of the screw rod 14 is rotatably installed on one end of the extraction tube body 2, and a threaded hole 15 for accommodating the screw rod 14 is opened on the axial center line of the connecting sleeve 8.

[0028] As mentioned above, when using the moving mechanism provided by the utility model, the screw rod 14 in the moving mechanism is rotatably installed at one end of the extraction tube, and the connecting sleeve 8 is screwed on the screw rod 14 through the threaded hole 15. When the screw rod 14 is rotated, the connecting sleeve 8 is driven to move along the axial direction on the screw rod 14 through the worm gear principle, thereby driving the piston 7 to adjust its position in the storage bin 16.

[0029] Further, in order to drive the screw rod 14 to rotate, refer to Figure 2 As shown, a knob 1 for driving a screw rod 14 to rotate is installed at one end of the extraction tube body 2, an annular groove 12 is provided on the inner wall of the end of the extraction tube body 2, and a rotating seat 13 that can rotate in the annular groove 12 is provided at one end of the knob 1. The knob 1 is rotatably installed on the extraction tube through the rotating seat 13 and the annular groove 12. Since the knob 1 is connected to one end of the screw rod 14, the screw rod 14 can be driven to rotate when the knob 1 is rotated.

[0030] Further, in order to guide the axial movement of the piston 7, refer to Figure 2-4 As shown, the guide member includes a mounting frame 11 and a guide rod 10 mounted on the mounting frame 11. The mounting frame 11 is mounted on the inner wall of the extraction pipe body 2. A guide hole 9 for accommodating the guide rod 10 is provided in the axial direction on the connecting sleeve 8. The guide rod 10 and the connecting sleeve 8 are installed in parallel through the mounting frame 11. Two guide rods 10 are provided in the figure, and one guide rod 10 can also be provided. The guide rod 10 extends to the inside of the connecting sleeve 8 through the guide hole 9, so that the piston 7 moves in the axial direction on the guide rod 10 through the connecting sleeve 8. A through hole for the screw rod 14 to pass through is provided on the mounting frame 11 in the figure to prevent the mounting frame 11 from affecting the rotation of the screw rod 14.
