Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically a multi-channel manual pipette holder. Background Technology

[0002] Pipettes are commonly used liquid transfer tools in laboratories. Multi-channel manual pipettes (such as 8-channel pipettes) are widely used in scenarios such as ELISA plate testing and microplate experiments because they can transfer multiple samples simultaneously. To avoid contamination or damage caused by haphazard placement of pipettes, laboratories usually use stands to store them. The storage method is simple: just hang the pipette's tabs on the hanging rod.

[0003] However, it has been found that common pipette stands have multiple aspiration needles under the pipetting assembly of multichannel pipettes. These pipette tips are usually conical hollow tubular structures. After the pipette is hung on the stand, these needles are exposed and dust can easily enter them, thus affecting subsequent liquid aspiration.

[0004] Therefore, it is necessary to provide a new multi-channel manual pipette holder to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-channel manual pipette holder that can block the port of the aspiration needle and prevent the pipette from easily slipping out.

[0006] To solve the above-mentioned technical problems, the multi-channel manual pipette holder provided by this utility model includes: two support bases, two standing plates fixedly installed on the top of the two support bases, two hanging beams fixedly installed on the side of the two standing plates that are close to each other, and multiple elastic buckles fixedly installed on the side of the two hanging beams that are far from each other. Each of the multiple elastic buckles has a slot on its inner wall on both sides. Multiple protective covers are provided between the two standing plates, each protective cover being located below the multiple elastic buckles. Rubber sealing gaskets are fixedly installed on the bottom inner wall of each of the multiple protective covers. A lifting unit is provided between the two standing plates to drive the protective covers upwards. The lifting unit includes a support plate fixedly installed between the two standing plates. A lifting screw is threaded onto the support plate, and a lifting block is threaded onto the lifting screw. Mounting panels are fixedly installed on both sides of the lifting blocks, and each of the multiple protective covers is fixedly connected to its corresponding mounting panel.

[0007] Preferably, vertical slide rods are fixedly installed on the opposite sides of the two standing plates, and sliding arms are slidably installed on the two vertical slide rods. The opposite sides of the two sliding arms penetrate the corresponding standing plates and are slidably connected to the corresponding standing plates. A common downward pressing connecting piece is fixedly installed on the opposite sides of the two sliding arms. Multiple limiting pressure pieces are fixedly installed on both sides of the downward pressing connecting piece. The multiple limiting pressure pieces are located below the multiple elastic buckles. A sponge pad is fixedly installed at the bottom of the multiple limiting pressure pieces. The lifting screw penetrates the downward pressing connecting piece and does not contact the downward pressing connecting piece.

[0008] Preferably, locking bolts are threaded onto the opposite sides of the two sliding arms, and the ends of the two locking bolts abut against the two vertical sliding rods respectively.

[0009] Preferably, the same end support plate is fixedly installed on the side of the two standing plates that are close to each other, and the bottom end of the lifting screw is rotatably connected to the end support plate.

[0010] Preferably, two limiting rods are fixedly installed on the top of the bearing plate, the bottom ends of the two limiting rods are fixedly connected to the end support plate, the two limiting rods pass through the lifting block and are slidably connected to it, and the limiting rods pass through the pressing connecting piece and do not contact the pressing connecting piece.

[0011] Preferably, the pressing connecting piece has an avoidance opening, and the lifting screw and the two limiting rods all pass through the avoidance opening and do not contact the inner wall of the avoidance opening.

[0012] Preferably, diagonal braces are fixedly installed on both sides of the two standing plates, and the bottoms of the four diagonal braces are fixedly connected to the corresponding support bases.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-7 The multi-channel manual pipette holder includes: two support bases 1, with two standing plates 2 fixedly mounted on the top of the two support bases 1. To improve stability and prevent tipping, diagonal braces are fixedly mounted on both sides of the two standing plates 2. The bottoms of the four diagonal braces are fixedly connected to the corresponding support bases 1. Two hanging beams 3 are fixedly mounted on the side of the two standing plates 2 that are close to each other, and multiple elastic buckles 4 are fixedly mounted on the side of the two hanging beams 3 that are far from each other, thus forming two rows of hanging components, which can increase the number of hanging components. The inner walls of the multiple elastic buckles 4 are provided with slots 5 on both sides, which can hold the pipette in the slots 5. The elastic buckles 4 also have a certain damping effect. Multiple protective covers 10 are provided between the two standing plates 2. The protective covers 10 are located below multiple elastic buckles 4. Each protective cover 10 has an open top and a rubber sealing gasket 11 is fixedly installed on the bottom inner wall of each protective cover 10. When the aspiration needle under the pipette enters the protective cover 10, it finally comes into contact with the rubber sealing gasket 11, thus forming a certain sealing effect and preventing dust. A lifting unit is provided between the two standing plates 2 to drive the protective covers 10 to rise. The lifting unit includes a support plate 6, which is fixedly installed between the two standing plates 2. A lifting screw 7 is threaded on the support plate 6, and a lifting block 8 is threaded on the lifting screw 7. Mounting panels 9 are fixedly installed on both sides of the lifting blocks 8, and multiple protective covers 10 are fixedly connected to the corresponding mounting panels 9.

[0018] In the above method, in order to achieve a holding effect on the pipette and prevent it from easily slipping off the hanging beam 3 after being inserted into the elastic buckle 4, vertical slide rods 12 are fixedly installed on the opposite sides of the two standing plates 2. Sliding arms 13 are slidably installed on each of the two vertical slide rods 12. The sides of the two sliding arms 13 that are close to each other penetrate the corresponding standing plate 2 and are slidably connected to it. A single downward pressing connecting piece 14 is fixedly installed on the side of the two sliding arms 13 that are close to each other. Multiple limiting pressure pieces 15 are fixedly installed on both sides of the downward pressing connecting piece 14. These multiple limiting pressure pieces 15 are respectively located below the multiple elastic buckles 4. Each of the multiple limiting pressure plates 15 has a sponge pad 16 fixedly installed at its bottom. The lifting screw 7 passes through the lower pressure connecting plate 14 and does not contact the lower pressure connecting plate 14. By lowering the sliding arm 13, the multiple limiting pressure plates 15 can be lowered. When the sponge pad 16 contacts the top plane of the lower half of the pipetting assembly of the multichannel pipette, a pressing and holding effect will be formed. After the limiting pressure plates 15 form a holding effect on the pipette, in order to form a fixing effect on the sliding arm 13, locking bolts 17 are threaded on the side of the two sliding arms 13 that are far apart from each other. The ends of the two locking bolts 17 abut against the two vertical slide rods 12 respectively.

[0019] In this method, in order to make the lifting block 8 form a stable linear lifting, the same end support plate is fixedly installed on the side of the two standing plates 2 that are close to each other. The bottom end of the lifting screw 7 is rotatably connected to the end support plate. Two limit rods are fixedly installed on the top of the bearing plate 6. The bottom ends of the two limit rods are fixedly connected to the end support plate. The two limit rods pass through the lifting block 8 and are slidably connected to it. The limit rods pass through the pressing connecting piece 14 and do not contact the pressing connecting piece 14.

[0020] In this method, in order to prevent interference between the pressing connecting plate 14 and the lifting screw 7, a clearance opening is provided on the pressing connecting plate 14. The lifting screw 7 and the two limit rods all pass through the clearance opening and do not contact the inner wall of the clearance opening.

[0021] The working principle of the multi-channel manual pipette holder provided by this utility model is as follows: When placing a multichannel pipette, first take out one pipette and insert it into one of the elastic clips 4. During the insertion process, the opening of the elastic clip 4 deforms first and finally fully engages with the slot 5 inside the elastic clip 4. Then press down until the hanging lug on it presses against the hanging beam 3. Then, insert the remaining pipettes into the corresponding elastic clips 4 in the same way. Then, first rotate the two locking bolts 17 in reverse to separate them from the corresponding vertical slide rods 12. Then, let the sliding arm 13 move down with the lower pressure connecting piece 14. Finally, let the sponge pads 16 on the multiple limiting pressure pieces 15 contact the lower half of their respective pipettes, locking the pipettes so that they cannot be lifted. Then, retighten the two locking bolts 17 so that the two locking bolts 17 re-engage and lock with the corresponding vertical slide rods 12. Then, turn the lifting screw 7 clockwise, and the lifting block 8 will lift up multiple protective covers 10, so that the aspiration needles under multiple pipettes can enter the corresponding protective covers 10 and come into contact with the rubber sealing gaskets 11 on the bottom inner wall of the protective cover 10, thus completing the placement of the pipettes.

[0022] Compared with related technologies, the multi-channel manual pipette holder provided by this utility model has the following advantages: This utility model provides a multi-channel manual pipette holder. Through the cooperation of the hanging beam 3, elastic buckle 4 and limiting pressure plate 15, the pipette can be reliably held in place, ensuring a stable hanging effect on the hanging beam 3 and preventing it from easily falling off. Furthermore, after the pipette is hung on the hanging beam 3, the protective cover 10 can wrap around the aspiration needle, and the rubber sealing gasket 11 provides good dust protection by contacting the tip of the needle.
