In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "set", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] As Figures 1 to 5As shown in the figure, the pipette tip storage and induction device of the present utility model includes: a base 1, on which a positioning rod 2 is arranged; a first storage part 3 and a second storage part 4, the first storage part 3 and the second storage part 4 are respectively rotatably arranged on the positioning rod 2, and a number of storage spaces 5 are formed in the first storage part 3 and the second storage part 4 in the vertical direction, and a pipette tip box 6 is arranged in the storage space 5; a positioning component, which is arranged in the base 1 and the first storage part 3 and the second storage part 4. When the first storage part 3 and the second storage part 4 rotate around the positioning rod 2 and fit together to close the storage space 5, or when the first storage part 3 and the second storage part 4 rotate around the positioning rod 2 to open their respective storage spaces 5 to a predetermined position, the positioning component can increase the resistance to the movement of the first storage part 3 and the second storage part 4, so as to limit the rotation of the first storage part 3 and the second storage part 4 around the positioning rod 2.

[0029] See Figure 1 、 Figure 2 , the structures of the first storage part 3 and the second storage part 4 are the same. Only the first storage part 3 is taken as an example below to describe the structures of the first storage part 3 and the second storage part 4.

[0030] See Figure 2 、 Figure 4 、 Figure 5 , the first storage part 3 is a rectangular structure with an opening on one side. The inside of the first storage part 3 is divided by a number of partitions in the vertical direction to form a number of storage spaces 5. A pipette tip box 6 is placed in each storage space 5 from the opening. It can be understood that the storage specifications of the pipette tip boxes 6 placed in each storage space 5 can be inconsistent, so as to facilitate the first storage part 3 and the second storage part 4 to store different specifications of pipette tips.

[0031] See Figure 2 , both the first storage part 3 and the second storage part 4 can rotate around the positioning rod 2. However, the rotation positions of the first storage part 3 and the second storage part 4 are restricted by the positioning component. That is, when the first storage part 3 and the second storage part 4 are in contact with each other and at a predetermined position, they will be restricted by the positioning component, increasing the resistance when the first storage part 3 and the second storage part 4 are opened. At the same time, when the first storage part 3 or the second storage part 4 rotates and separates and rotates to a certain angle, under the action of the positioning component, the rotation positions of the first storage part 3 and the second storage part 4 will be subject to a certain resistance, so as to realize the limitation of the positions of the first storage part 3 and the second storage part 4 after being opened, facilitating the experimenter to take out the pipette tip box 6, which has practicability.

[0032] In one or more embodiments, the positioning assembly includes a first magnet respectively disposed at the bottom of the first storage portion 3 and the bottom of the second storage portion 4, a second magnet 71 disposed at the first position 101 on the base 1, and a third magnet 72 disposed at the second position 102 on the base 1. The first position 101 and the second position 102 are located on the rotation paths of the first storage portion 3 and the second storage portion 4, and the first magnet attracts the second magnet 71 and the third magnet 72 magnetically.

[0033] See Figures 1 to 3 , first magnets are disposed at the bottoms of the first storage portion 3 and the second storage portion 4 on the sides close to each other. The first position 101 of the base 1 is the position when the storage spaces 5 of the first storage portion 3 and the second storage portion 4 are closed by fitting together. The second position 102 of the base 1 corresponds to a certain position when the first magnet rotates around the positioning rod 2. That is, there are two second positions 102 of the base 1, corresponding to the first storage portion 3 and the second storage portion 4 respectively.

[0034] In the initial state, the storage spaces 5 of the first storage portion 3 and the second storage portion 4 are closed by fitting together, and the first magnets disposed at the bottoms of the first storage portion 3 and the second storage portion 4 attract the second magnet 71 at the first position 101 of the base 1 magnetically.

[0035] When it is necessary to open the first storage portion 3 and the second storage portion 4 to take out the pipette tip box 6, the experimenter can rotate the first storage portion 3 and the second storage portion 4 in opposite directions to separate them. At this time, the first magnet no longer attracts the second magnet 71 at the first position 101 of the base 1. When the first storage portion 3 or the second storage portion 4 moves to the second position 102, the first magnet at the bottom of the first storage portion 3 or the second storage portion 4 attracts the third magnet 72 at the second position 102 of the base 1, so as to realize the limitation of the position of the first storage portion 3 or the second storage portion 4, reduce the problem that the first storage portion 3 or the second storage portion 4 moves when the experimenter takes out the pipette tip box 6, and improve the use effect of the present application.

[0036] In one or more embodiments, a pressing cover 9 for pressing and closing the top surface of the pipette tip box 6 is disposed at the top of each storage space 5 through an elastic member 8; the elastic member 8 is a spring or an elastic steel; a wedge surface 11 is formed on the surface of the pressing cover 9 on the side far from the opening of the storage space 5, and a clamping portion 61 adapted to the wedge surface 11 is formed at the top end of the pipette tip box 6; the first storage portion 3 and the second storage portion 4 are provided with chutes corresponding to the parts in each storage space 5, and a push block 12 is slidably installed in the chutes.

[0037] See Figure 5, when the pipette tip box 6 is completely within the storage space 5, the engaging portion 61 of the pipette tip box 6 is adapted to the wedge-shaped surface 11 of the gland 9, and the elastic member 8 is in a compressed state; by the limitation of the position of the pipette tip box 6 by the gland 9, the stability of the pipette tip box 6 placed in the storage space 5 can be ensured, which is convenient for transportation and taking.

[0038] When it is necessary to take out the pipette tip box 6, by pushing the push block 12 in the direction of the interior of the storage space 5, so that the push block 12 presses the side of the pipette tip box 6, making the engaging portion 61 of the pipette tip box 6 located directly below the gland 9. At the same time, a part of one side of the pipette tip box 6 extends out of the storage space 5. At this time, by taking the part of the pipette tip box 6 that extends out of the storage space 5, the pipette tip box 6 can be taken out of the storage space 5, which has the characteristics of simple structure and convenient operation and has practicability.

[0039] In one or more embodiments, each storage space 5 is configured with a telescopic rod 13 for connecting the top surface of the storage space 5 and the top surface of the gland 9. See Figure 5 , by connecting the storage space 5 and the gland 9 through the telescopic rod 13, a restriction on the gland 9 only in the vertical direction can be formed, avoiding the problem that the position of the gland 9 is offset when the pipette tip box 6 is taken out of the storage space 5.

[0040] In one or more embodiments, the first storage part 3 and the second storage part 4 are made of hard plastic or glass.

[0041] In one or more embodiments, the gland 9 is made of polyethylene material.

[0042] In one or more embodiments, a label area is formed on the surface of the pipette tip box 6 near the opening of the storage space 5. By attaching a label to the label area of the pipette tip box 6, it is convenient for the staff to quickly distinguish the information of the pipette tips stored in each pipette tip box 6.

[0043] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
