A magnetic adsorption extraction support

Abstract

This utility model relates to the field of support technology, and more particularly to a magnetic adsorption extraction support, comprising a base, a fixing seat, a reagent tube, and a magnetic block. The fixing seat is fixedly connected to the base, and the fixing seat has multiple arc-shaped grooves. The reagent tube is placed in the arc-shaped grooves, and the magnetic block is embedded in the arc-shaped grooves. By pressing down on the top plate, the top plate drives the sliding rod, the first conical block, and the second conical block to move down, thereby compressing the first elastic element. The inclined surface of the first conical block presses against the two limiting blocks, causing it to move outward against the second elastic element. After the first conical block passes the two limiting blocks, the second elastic element rebounds, causing the limiting blocks to reset and lock above the first conical block, locking the top plate in the pressed position. This ensures that the limiting ring presses against the reagent tube, preventing the reagent tube from loosening due to vibration or slight impact.

Description

Technical Field

[0001] This utility model relates to the field of stent technology, and in particular to a magnetic adsorption extraction stent. Background Technology

[0002] An extraction support is generally a laboratory instrument or device used to support, fix, or assist a sample and maintain stability during the extraction process.

[0003] Patent CN218078029U discloses a test tube holder. It includes a stable base, a test tube tray mounting bracket fixedly mounted on the top of the stable base, a draining platform fixedly mounted on one side of the top of the test tube tray mounting bracket, and a mounting plate fixedly mounted on the inner wall of one side of the draining platform. The mounting plate has a sliding mounting groove inside. When using this patent, test tubes are placed on the test tube tray. However, in the aforementioned prior art, during storage, vibration or slight collisions can cause the test tubes to shake, leading to splashing of contents and cross-contamination of samples.

[0004] Therefore, there is a need to provide a magnetic adsorption extraction holder that prevents shaking. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents mentioned above, which are prone to shaking of reagent tubes during storage due to vibration or slight collision, resulting in splashing of contents and cross-contamination of samples, this utility model provides a shaking-proof magnetic adsorption extraction holder.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a magnetic adsorption extraction support, comprising a base, a fixed seat, a reagent tube, and a magnetic block. The fixed seat is fixedly connected to the base, and the fixed seat has multiple arc-shaped grooves. The reagent tube is placed in each arc-shaped groove, and the magnetic block is embedded in each arc-shaped groove. The support also includes a sliding plate, a first elastic element, a sliding rod, a top plate, a limiting ring, a first conical block, a second conical block, a limiting block, a guide rod, and a second elastic element. The fixed seat has a sliding groove, and the sliding plate is slidably disposed within the sliding groove. A sliding rod is fixedly connected to the moving plate. A first elastic element connects the sliding plate to the fixed seat. A top plate is fixedly connected to the sliding rod. A limit ring is fixedly connected to the upper part of the sliding rod. A second conical block is slidably arranged on the sliding rod. The limit ring is located above the second conical block. A first conical block is slidably arranged on the sliding rod. Two guide grooves are opened on the fixed seat. A guide rod is slidably arranged in the guide groove. A limit block is fixedly connected to the guide rod. A second elastic element is sleeved on the guide rod. The two ends of the second elastic element are connected to the fixed seat and the limit block, respectively.

[0007] Furthermore, it also includes buffer dampers, connecting rings and collars. Multiple buffer dampers are provided on the top plate, and collars are provided between the multiple buffer dampers. Multiple collars are provided on the connecting ring.

[0008] Furthermore, it also includes rubber blocks, with rubber blocks installed on the top plate.

[0009] Furthermore, it also includes anti-slip pads, with anti-slip pads embedded in the base.

[0010] Furthermore, the rubber block is equipped with anti-slip texture.

[0011] Furthermore, the limiting block is trapezoidal.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By pressing down on the top plate, the top plate drives the sliding rod, the first conical block and the second conical block to move down, and the first elastic element is compressed accordingly. The inclined surface of the first conical block squeezes the two limiting blocks, so that it overcomes the second elastic element and moves outward. After the first conical block passes the two limiting blocks, the second elastic element rebounds and drives the limiting blocks to reset, so that it is locked above the first conical block, locking the top plate in the pressing position, so that the limiting ring presses the reagent tube and prevents the reagent tube from loosening due to vibration or slight collision.

[0013] 2. The buffer damper provides a smooth and controllable downward pressure and absorbs vibrations to prevent rigid impacts from damaging the reagent tubes. The limiting ring ensures that each reagent tube is pressed down independently and evenly, preventing it from popping out or shifting from the arc groove during operation.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1: A magnetic adsorption extraction scaffold, see reference Figures 1-4 As shown, the device includes a base 1, a fixed seat 2, a reagent tube 301, and a magnetic block 4. The fixed seat 2 is welded to the top of the base 1. Multiple arc-shaped grooves 3 are evenly spaced on the fixed seat 2, and the reagent tube 301 is placed in each arc-shaped groove 3. The magnetic block 4 is embedded in the arc-shaped groove 3 and attracts the reagent tube 301. The device also includes a sliding plate 6, a first elastic element 7, a sliding rod 8, a top plate 801, a limiting ring 802, a first conical block 9, a second conical block 10, a limiting block 13, a guide rod 12, and a second elastic element 14. A sliding groove 5 is opened in the middle of the fixed seat 2, and the sliding plate 6 is slidably arranged in the sliding groove 5. The sliding rod 8 is welded to the top of the sliding plate 6. The first elastic element 7 connects the sliding plate 6 and the fixed seat 2. The top of the sliding rod 8 is connected by bolts. The system is equipped with a top plate 801, a limiting ring 802 fixedly connected to the upper part of the sliding rod 8, a second conical block 10 slidably mounted on the sliding rod 8, the limiting ring 802 being located above the second conical block 10, the second conical block 10 slidably mounted on the upper part of the sliding rod 8, and a first conical block 9 slidably mounted on the lower part of the sliding rod 8. The first conical block 9 is an inverted cone, and the second conical block 10 is a regular cone. The fixed base 2 has guide grooves 11 on both the left and right sides, and a guide rod 12 slidably mounted in the guide grooves 11. A limiting block 13 is fixedly connected to the end of the guide rod 12, and a second elastic element 14 is sleeved on the guide rod 12. The two ends of the second elastic element 14 are respectively connected to the fixed base 2 and the limiting block 13. The limiting block 13 is located below the first conical block 9 and can be locked above the second conical block 10.

[0021] See Figure 1 , Figure 2 and Figure 4 As shown, it also includes a rubber block 18, and a rubber block 18 is provided on the top of the top plate 801.

[0022] See Figure 2 As shown, it also includes an anti-slip pad 19, which is embedded in the bottom of the base 1.

[0023] See Figure 1 and Figure 2 As shown, the rubber block 18 has an anti-slip texture.

[0024] See Figure 2 and Figure 3 As shown, the limiting block 13 is trapezoidal.

[0025] When using this support, the anti-slip pad 19 utilizes high-friction materials such as rubber or silicone to increase the friction between the support and the experimental table surface. In the initial state, the sliding rod 8 and the sliding plate 6, supported by the first elastic element 7, keep the top plate 801 in the raised position, facilitating the placement of the reagent tube 301. When it is necessary to fix the reagent tube 301, press the top plate 801 downwards. The top plate 801 drives the sliding rod 8, the first conical block 9, and the second conical block 10 to move downwards. The first elastic element 7 is compressed accordingly. The inclined surface of the first conical block 9 presses against the two limiting blocks 13, causing it to move outwards against the second elastic element 14. After the first conical block 9 passes the two limiting blocks 13, the second elastic element 14 rebounds, causing the limiting blocks 13 to reset and lock above the first conical block 9, locking the top plate 801 in the pressed position. This causes the collar 17 to press down on the reagent tube 301, preventing the reagent tube 301 from loosening due to vibration or slight impact. When it is necessary to release, press the top plate 801 firmly. The top plate 801 drives the sliding rod 8, sliding plate 6, first conical block 9, and second conical block 10 to move downwards, compressing the first elastic element 7. The second conical block 10 presses the limiting block 13 outwards and presses the second elastic element 14. After the second conical block 10 passes the two limiting blocks 13, the first elastic element 7 returns to its original position, causing the sliding rod 8, sliding plate 6, first conical block 9, and second conical block 10 to move upwards. The bottom of the limiting block 13 first abuts against the top of the second conical block 10, and the sliding rod 8 drives the sliding plate 6 to move downwards. 6 and the first conical block 9 continue to move upward. When the first conical block 9 contacts the second conical block 10, the first conical block 9 pushes the second conical block 10 to slide upward. The second conical block 10 pushes open the limiting block 13. The sliding rod 8 drives the first conical block 9 and the second conical block 10 to continue to move upward. The first conical block 9 passes the limiting block 13, thereby restoring the sliding rod 8 and the top plate 801 to their initial height. The rubber block 18 set on the top of the top plate 801 provides a soft and comfortable touch when pressed.

[0026] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes a buffer damper 15, a connecting ring 16 and a collar 17. Multiple buffer dampers 15 are evenly spaced at the bottom of the top plate 801, and a connecting ring 16 is arranged between the multiple buffer dampers 15. Multiple collars 17 are evenly spaced at the bottom of the connecting ring 16, and the number of collars 17 is equal to the number of reagent tubes 301.

[0027] When the top plate 801 is pressed and locked, the buffer damper 15 and the connecting ring 16 descend accordingly, so that the collar 17 is fitted onto or pressed on the top of the reagent tube 301. This allows the buffer damper 15 to provide a smooth and controllable downward pressure and absorb vibration, preventing rigid impact from damaging the reagent tube 301. The collar 17 ensures that each reagent tube 301 is pressed independently and evenly, preventing it from popping out or shifting from the arc groove 3 during operation. At the same time, the adsorption force of the magnetic block 4 further ensures the stability of the bottom of the reagent tube 301.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
