Description

Technical Field

[0001] The utility model relates to the technical field of detection and testing equipment, in particular to a pipette rack with a wastewater collection function. Background Art

[0002] Pipettes are often used during inspection and testing. During the use or drying of the pipette, some solution or water will inevitably remain at the end. Under the action of gravity, the residual solution or water will drip to the bottom of the pipette rack, which may cause the bottom of the pipette rack to be corroded, making it difficult to clean it subsequently. In addition, the contact position between the existing pipette rack and the pipette end is usually conical. However, during use, the pipette end may be damaged during the process of taking and placing due to improper operation of the staff, resulting in insufficient sealing of the pipette end, which may easily leak from the pipette. In addition, the solution residue may accumulate in the conical hole in the pipette rack. Due to its small size, it is difficult to clean subsequently. Therefore, it may cause inaccurate experimental data when the pipette is used subsequently. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a pipette rack with a wastewater collection function, which can increase the service life of the pipette and the pipette rack and facilitate cleaning of the pipette rack.

[0004] The technical solution of the utility model is: a pipette rack with a wastewater collection function, comprising a bracket body, a plurality of connecting rods fixedly connected to the bracket body, a first support plate fixedly connected to the connecting rods, a second support plate fixedly connected to the connecting rods, a waste liquid collection bucket connected to the bottom of the second support plate, a connecting pipe connected to the waste liquid collection bucket and a waste liquid collection bin connected to the connecting pipe, the first support plate is located directly above the second support plate, the first support plate is provided with a plurality of limiting holes evenly distributed on the first support plate, the second support plate is provided with a plurality of tapered holes evenly distributed on the second support plate, and the central axes of the limiting holes correspond one-to-one with the central axes of the tapered holes respectively.

[0005] By adopting the above technical solution, when the pipette needs to be placed on the pipette rack, first, align the idler end of the pipette with the limiting hole and insert it, and then insert the end of the pipette into the tapered hole. When the waste liquid or water remaining on the pipette flows out from the pipette wall, since a waste liquid collecting bucket is provided at the bottom of the second support plate, the waste liquid will flow into the waste liquid collecting bucket through the tapered hole, and finally, it will be transmitted to the waste liquid collecting bin through the connecting tube connected to the waste liquid collecting bin. This can prevent the bottom of the pipette rack from being corroded and damaged by the residual waste liquid. When cleaning, only the waste liquid collecting bin and the connecting tube need to be cleaned, which greatly reduces the difficulty of cleaning.

[0006] The present invention is further provided with a connecting block at the bottom of the second supporting plate, the connecting block is in a circular ring shape, and the connecting block is threadedly connected to the waste liquid collection bucket.

[0007] By adopting the above technical solution, since the connecting block is threadedly connected to the waste liquid collecting bucket, after the pipette rack is used for a long time, the waste liquid collecting bucket can be removed from the bottom of the second support plate and cleaned separately, which can further reduce the difficulty of cleaning the entire pipette rack and increase the service life of the pipette rack.

[0008] The utility model is further configured as follows: a rubber sleeve is provided on the tapered hole, and the rubber sleeve is adapted to the shape and size of the tapered hole.

[0009] By adopting the above technical solution, since a rubber sleeve is provided on the conical hole, the rubber sleeve can protect the pipette placed on the pipette rack, thereby preventing the pipette from being damaged due to severe friction between the end of the pipette and the conical hole due to careless operation by the staff, thereby increasing the service life of the pipette placed on the pipette rack.

[0010] The utility model is further configured as follows: it also includes a rubber pad and several fixing blocks fixedly connected to the rubber pad, the rubber sleeve is evenly distributed on the rubber pad, the rubber pad and the rubber sleeve are integrally formed, the cross-sectional shape of the rubber pad is adapted to the cross-sectional shape and size of the second support plate, the second support plate is provided with several first positioning grooves, the first positioning grooves are adapted to the shape and size of the fixing blocks, and the first positioning grooves correspond one-to-one to the positions of the fixing blocks respectively, when the fixing blocks are respectively clamped on the first positioning grooves, the positions of the rubber sleeves correspond one-to-one to the positions of the tapered holes respectively.

[0011] With the above technical solution, when the fixing blocks are respectively clamped on the first positioning grooves, the positions of the rubber sleeves correspond one-to-one to the positions of the tapered holes. Therefore, when the pipette rack needs to be cleaned, the rubber pad can be pulled out, thereby allowing the fixing block to withdraw from the first positioning groove. At the same time, since the rubber sleeves are evenly distributed on the rubber pads, the rubber sleeves will also withdraw from the tapered holes after the rubber pads are pulled out. This makes it convenient for users to further clean the rubber sleeves and the tapered holes, avoiding waste liquid from remaining at the joint between the rubber sleeves and the tapered holes, thereby ensuring that the pipette ends used subsequently will not be contaminated with residual waste liquid, thereby improving the accuracy of the experiment.

DETAILED DESCRIPTION

[0014] like Figure 1 As shown, a pipette rack with a wastewater collection function includes a bracket body 1, several connecting rods 2 fixedly connected to the bracket body 1, a first support plate 3 fixedly connected to the connecting rod 2, a second support plate 4 fixedly connected to the connecting rod 2, a waste liquid collection bucket 5 connected to the bottom of the second support plate 4, a connecting pipe 6 connected to the waste liquid collection bucket 5 and a waste liquid collection tank 7 connected to the connecting pipe 6, the first support plate 3 is located directly above the second support plate 4, the first support plate 3 is provided with several limiting holes 8 evenly distributed on the first support plate 3, the second support plate 4 is provided with several tapered holes 9 evenly distributed on the second support plate 4, and the central axes of the limiting holes 8 correspond one-to-one with the central axes of the tapered holes 9 respectively. When the pipette needs to be placed on the pipette rack, first, align the idle end of the pipette with the limiting hole 8 and insert it, and then insert the end of the pipette into the tapered hole 9. When the waste liquid or water remaining on the pipette flows out from the pipette wall, since a waste liquid collecting bucket 5 is provided at the bottom of the second support plate 4, the waste liquid will flow into the waste liquid collecting bucket 5 through the tapered hole 9, and finally, it will be transmitted to the waste liquid collecting bin 7 through the connecting tube 6 connected to the waste liquid collecting bin 5. This can prevent the bottom of the pipette rack from being corroded and damaged by the residual waste liquid. When cleaning, only the waste liquid collecting bin 7 and the connecting tube 6 need to be cleaned, which greatly reduces the difficulty of cleaning.

[0015] A connecting block 10 is provided at the bottom of the second supporting plate 4 . The connecting block 10 is annular and is threadedly connected to the waste liquid collecting hopper 5 .

[0016] Since the connecting block 10 is threadedly connected to the waste liquid collecting hopper 5, after the pipette rack has been used for a long time, the waste liquid collecting hopper 5 can be removed from the bottom of the second support plate 4 and the waste liquid collecting hopper 5 can be cleaned separately, which can further reduce the difficulty of cleaning the entire pipette rack and increase the service life of the pipette rack.

[0017] A rubber sleeve 11 is provided on the tapered hole 9 , and the rubber sleeve 11 is adapted to the shape and size of the tapered hole 9 .

[0018] Since the rubber sleeve 11 is provided on the conical hole 9, the rubber sleeve 11 can protect the pipette placed on the pipette rack, preventing the pipette from being damaged due to severe friction between the end of the pipette and the conical hole 9 due to careless operation by the staff, thereby improving the service life of the pipette placed on the pipette rack.

[0019] It also includes a rubber pad 12 and several fixing blocks 13 fixedly connected to the rubber pad 12. The rubber sleeve 11 is evenly distributed on the rubber pad 12. The rubber pad 12 and the rubber sleeve 11 are integrally formed. The cross-sectional shape of the rubber pad 12 is adapted to the cross-sectional shape and size of the second support plate 4. The second support plate 4 is provided with several first positioning grooves 14. The first positioning grooves 14 are adapted to the shape and size of the fixing blocks 13, and the first positioning grooves 14 correspond one-to-one with the positions of the fixing blocks 13 respectively. When the fixing blocks 13 are respectively snapped onto the first positioning grooves 14, the positions of the rubber sleeves 11 correspond one-to-one with the positions of the tapered holes 9 respectively.

[0020] Since when the fixing blocks 13 are respectively engaged with the first positioning grooves 14, the positions of the rubber sleeves 11 correspond one-to-one to the positions of the tapered holes 9. Therefore, when the pipette rack needs to be cleaned, the rubber pads 12 can be pulled out, so that the fixing blocks 13 can be withdrawn from the first positioning grooves 14. At the same time, since the rubber sleeves 11 are evenly distributed on the rubber pads 12, after the rubber pads 12 are pulled out, the rubber sleeves 11 will also be withdrawn from the tapered holes 9. This makes it convenient for users to further clean the rubber sleeves 11 and the tapered holes 9, avoiding waste liquid from remaining at the joints between the rubber sleeves 11 and the tapered holes 9, thereby ensuring that the pipette ends used subsequently will not be contaminated with residual waste liquid, thereby improving the accuracy of the experiment.
