Description

Technical Field

[0001] The utility model relates to the technical field of biological laboratories, in particular to a liquid transfer gun support which is convenient for taking and placing. Background Art

[0002] A biological laboratory, also known as a biosafety laboratory, is a place where experiments related to biology are conducted. A pipette is a type of pipette, commonly used to transfer small or trace amounts of liquid in biological laboratories. When sampling in the laboratory, one usually holds the pipette in one hand and the solution container in the other, and inserts the pipette into the container to take out a quantitative solution. In addition, each experiment usually requires the extraction of multiple solutions for the experiment. After the experiment is completed, people usually use a pipette stand to temporarily put the pipette on hold.

[0003] The existing pipette holder generally limits the position by relying on the aperture matched with the pipette and the flange on the top of the pipette. This fixing method not only has poor stability, but also because the amount of extracted solution in the experiment is different, the size and specifications of the pipette used are also different. The existing pipette holder has a limited limiting range for the pipette and cannot maintain a stable limiting effect for pipettes of different outer diameters. Therefore, different specifications of holders need to be used to fix the pipette each time, and the efficiency of taking and placing is low. Therefore, a pipette holder that is easy to take and place is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, two through grooves are provided on one side of the adjustment box close to the hollow frame, and rotating blocks are fixedly installed on opposite sides of the two limiting screws.

[0010] Furthermore, the pipette body is located between two arc-shaped clamping plates, a slot is provided inside the rotating rod, and the slot is adapted to the fixed plug rod.

[0019] See also Figure 1-3 In this embodiment, a pipette holder that is easy to take and place includes a base plate 1 and two pipette bodies 5. A support plate 2 is fixedly installed on the top of the base plate 1, and hollow frames 3 are fixedly installed on the left and right sides of the support plate 2. Adjustment boxes 4 are fixedly installed on the opposite sides of the two hollow frames 3, and fixed structures 6 are provided in the two adjustment boxes 4.

[0020] The fixed structure 6 includes a rotating rod 601, which is rotatably installed on the inner bottom wall of the adjustment box 4. A gear 602 is fixedly mounted on the surface of the rotating rod 601. Racks 603 are meshed on the front and rear sides of the gear 602. Moving bars 604 are fixedly mounted on the opposite sides of the two racks 603. Limiting screws 605 are threadedly connected inside the two moving bars 604. Arc-shaped clamping plates 606 are fixedly mounted on the opposite sides of the two limiting screws 605. A vertical plate 607 is fixedly mounted on the top of the adjustment box 4. A fixed plug 608 is inserted into the vertical plate 607, and a spring 609 is mounted on the surface of the fixed plug 608.

[0021] like Figure 1 and Figure 2 As shown, a rotating plate is fixedly installed on the top of the rotating rod 601, and the rotating plate is provided to facilitate the rotation of the rotating rod 601. The inner bottom walls of the two adjustment boxes 4 are fixedly installed with rotating seats, and the rotating seats are provided to facilitate the stable rotation of the rotating rod 601.

[0022] like Figure 1 and Figure 2 As shown, a slider is fixedly installed on the side of the moving bar 604 away from the hollow frame 3, a slide rail is provided on the side of the adjustment box 4 away from the hollow frame 3, and a slider is slidably installed on the slide rail. Through this arrangement, the moving bar 604 can slide stably.

[0023] like Figure 1 and Figure 2 As shown, two through slots are provided on one side of the adjustment box 4 close to the hollow frame 3, and the movable bar 604 extends to the inside of the hollow frame 3 through the through slots. Rotary blocks are fixedly installed on the opposite sides of the two limit screws 605, and the limit screws 605 can be rotated conveniently by the rotary blocks.

[0024] like Figure 2 and Figure 3As shown, the pipette body 5 is located between two arc-shaped clamping plates 606, a slot is provided inside the rotating rod 601, and the slot is adapted to the fixed plug rod 608, so that the fixed plug rod 608 can be inserted into the slot to fix the rotating rod 601, thereby preventing the failure of fixing the pipette body 5 due to the self-rotation of the gear 602.

[0025] like Figure 1 and Figure 3 As shown, one end of the spring 609 is fixedly connected to the surface of the vertical plate 607, and the other end is fixedly connected to the surface of the fixed plug rod 608. Two fixed plates are fixedly installed on the top of the bottom plate 1, and water collecting tables are installed on the top of the two fixed plates by bolts. The water collecting table is provided to catch the solution accidentally leaked from the pipette body 5 to prevent the solution from contaminating the bracket.

[0026] When implementing, follow these steps:

[0027] 1) First pull the fixed rod 608 to separate it from the rotating rod 601, thereby releasing the restriction on the movement of the rotating rod 601;

[0028] 2) Then, the rotating rod 601 is rotated, and the rotating rod 601 drives the two moving bars 604 to move relative to each other through the gear 602 and the two racks 603;

[0029] 3) After moving to a suitable distance, the fixed rod 608 fixes the rotating rod 601 through the reset action of the spring 609;

[0030] 4) Finally, hold the pipette body 5 with one hand so that it is located between the two arc-shaped clamping plates 606 , and use the other hand to rotate the limit screw 605 , and fix the pipette body 5 through the arc-shaped clamping plates 606 according to the specifications of the pipette body 5 .

[0031] To sum up, the easy-to-take-and-place pipette holder is provided with a fixing structure 6. When the pipette body 5 needs to be fixed on the pipette holder, the fixing rod 608 is pulled to disengage the rotating rod 601, and the gear 602 is driven to rotate by rotating the rotating rod 601. The gear 602 drives the two moving bars 604 to move relative to each other through the two racks 603. After moving to a suitable fixed position, the fixing rod 608 is released. The fixing rod 608 fixes the rotating rod 601 through the resetting action of the spring 609 to prevent the gear 602 from rotating. Then, the pipette body 5 is placed between the two arc-shaped clamping plates 606. According to the specifications of the pipette body 5, the rotating limit screw 605 drives the two arc-shaped clamping plates 606 to stably clamp the pipette body 5. Through the above-mentioned arrangement, the device can clamp pipette bodies 5 of different outer diameters without the need to replace different pipette holders, thereby improving the efficiency of taking and placing, and having practicality.
