Description

Technical Field

[0001] The utility model relates to the technical field of phospholipid sampling, in particular to a telescopic phospholipid sampler. Background Art

[0002] Phospholipids, also known as phospholipids or phospholipids, are lipids containing phosphoric acid and belong to the class of complex lipids. Phospholipids are the primary components of biological membranes and are divided into two main categories: glycerophospholipids and sphingomyelins, composed of glycerol and sphingosine, respectively. Phospholipids are amphiphilic molecules, with a hydrophilic nitrogen- or phosphorus-containing head at one end and a long, hydrophobic (lipophilic) hydrocarbon chain at the other. Due to production factors or temperature fluctuations, barreled lecithin can sometimes be solid. The relatively small opening of lecithin barrels makes sampling from within these barrels inconvenient. Utility Model Content

[0034] Example 2

[0035] See also Figure 1 and Figure 8 The utility model provides a technical solution: a scale 39 is provided on the outside of the insertion rod 2, the top of the insertion rod 2 extends to the top of the outer tube 1, and handles 46 are fixedly connected on both sides of the outer tube 1 to facilitate the operator to push the outer tube 1 and pull the outer tube 1 to move.

[0036] In summary, when the telescopic phospholipid sampler is used, the extension length of the collet 25 is adjusted according to the diameter of the phospholipid barrel, and then the operator rotates the second ball screw 29 so that the second ball screw 29 drives the first plug 30 to move, so that the bottom end of the first plug 30 moves out of the first column groove 31, and then the operator pulls the second storage box 28 to move, so that the second storage box 28 drives the first connecting block 27 and the telescopic column 24 to move, and adjusts the extension length of the collet 25. When the collet 25 extends to the specified length, the operator resets and rotates the second ball screw 29 so that the second ball screw 29 drives the first plug 30 to move, so that the bottom end of the first plug 30 is inserted into the corresponding first column groove 31, thereby adjusting the telescopic column 24 and the collet 25. The position is limited, and then the two collets 25 are placed on the barrel edge of the lecithin barrel to limit the position of the disc 3, and then the outer tube 1 is passed through the mounting groove 18 and inserted under the disc 3. In this process, the sampling tube 35 and the outer side of the outer tube 1 pass through the arc-shaped wiping block 21, and the arc-shaped wiping block 21 cleans and wipes the outer side of the sampling tube 35 and the outer tube 1. Then, the sampling tube 35 is inserted into the phospholipid inside the lecithin barrel, so that the phospholipid enters the sampling tube 35, so that the phospholipid pushes the second push block 41, the mounting seat 40 and the insertion rod 2 to move upward. The operator can obtain the amount of phospholipid sampled inside the sampling tube 35 by observing the scale 39 on the outside of the insertion rod 2 extending out of the outer tube 1. When the amount of phospholipid inside the sampling tube 35 reaches the requirement, the operator operates The operator rotates the first ball screw 5 so that the first ball screw 5 drives the bottom end of the second plug post 33 to move out of the second column groove 34. At this time, the support spring 9 pushes the first push block 7 to drive the push post 8, the second connecting block 32, the first storage box 6, the second mounting block 17 and the arc-shaped wiping block 21 to move toward the driving groove 4. Therefore, when the outer tube 1 and the sampling tube 35 are pulled out from the phospholipid barrel, the outer tube 1 and the sampling tube 35 will not contact the arc-shaped wiping block 21, thereby preventing the dirt on the surface of the arc-shaped wiping block 21 from contacting the surface of the outer tube 1 and the sampling tube 35. Then, after the outer tube 1 and the sampling tube 35 are taken out from the inside of the disc 3, the operator takes the outer tube 1 and the sampling tube 35 to the sample storage dish, and then the operator pushes the insertion rod 2 so that the insertion rod 2 pushes the mounting seat 4 0 and the second push block 41 push the phospholipid inside the sampling tube 35 out, so that the phospholipid falls into the sample storage dish for subsequent phospholipid sample testing, and remove the collet 25 from the edge of the phospholipid barrel, thereby removing the phospholipid barrel on the disc 3, and then the operator pulls the moving rod 13 to move upward, so that the moving rod 13 drives one end of the card column 14 to move out of the card slot 16, and then rotates the rotating block 12 to rotate the rotating block 12 to one side of the first mounting block 11, and then the second mounting block 17 and the arc-shaped wiping block 21, the bottom plate 19 and the rubber pad 22 can be taken out from the moving slot 10 and the mounting slot 18, and then the operator pulls the first storage box 6 to move, so that the first storage box 6 drives the second connecting block 32 and the first push block 7 and the push column 8 to move,The push column 8 pushes the first mounting block 11 to move, and then the operator rotates the first ball screw 5, so that the first ball screw 5 drives the second plug column 33 to reset and rotate, so that the bottom end of the second plug column 33 is inserted into the second column groove 34, thereby limiting and fixing the positions of the second connecting block 32, the first pushing block 7, the push column 8 and the first mounting block 11, and then putting the new second mounting block 17 and the arc-shaped wiping block 21 into the movable groove 10, so that the bottom plate 19 and the rubber pad 22 are located in the mounting groove 18, and then the operator resets and rotates the first mounting block 11 so that the clamping column 14 is located above the clamping groove 16, and then the operator releases the moving rod 13. At this time, the first limit spring 15 pushes the clamping column 14 to move downward, so that the clamping column 14 drives the moving rod 13 to move downward, so that the bottom end of the clamping column 14 is inserted into the clamping groove 16, thereby connecting the first mounting block 11 and the second mounting block 17.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
