Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nucleic acid extraction, in particular to a novel magnetic frame. Background Art
[0002] Magnetic bead extraction methods are divided into automated and manual extraction. Magnetic bead extraction is highly compatible with automated machines and is more suitable for projects with larger sample sizes. Automated extraction is the most commonly used method, but it requires specialized equipment—a nucleic acid extractor. When the sample size is small, automated extraction can cause instrument wear and waste of consumables. Manual extraction using a magnetic rack is more suitable. While existing conventional magnetic racks can meet general experimental needs, they still have many shortcomings.
[0003] Most magnetic stands have a single magnetic attraction position and a lower magnetic attraction range. When processing experiments with a large number of single samples, uneven elution will occur, resulting in sample waste. Utility Model Content
[0004] The utility model aims to solve the problem that most magnetic racks in the prior art have a single magnetic attraction position and a lower magnetic attraction range, which causes uneven elution and waste of samples when processing experiments with a large number of single samples.
[0005] In order to solve the above problems, the technical solution adopted by the present invention is:
[0006] A new type of magnetic rack comprises a base, a support plate is provided at one end of the base, an upper limit plate is fixedly connected to the upper end of the support plate, a number of test tubes are evenly arranged in the base and the upper limit plate, a position adjustment structure is provided on the support plate, the position adjustment structure comprises a slot plate slidably connected to the support plate, a pair of inclined slots are symmetrically provided at both ends of the slot plate, a first adjustment plate and a second adjustment plate slidably connected to the support plate are provided at one end of the test tube, a fixing pin is respectively provided on the first adjustment plate and the second adjustment plate and a magnetic column corresponding to the test tube is also respectively provided on the first adjustment plate and the second adjustment plate.
[0007] The position adjustment structure also includes a screw rotatably connected to the support plate, a fixed shaft block is provided at one end of the slot plate, the inner wall of the fixed shaft block is fixedly connected to a screw barrel threadedly connected to the screw, and both ends of the support plate are respectively provided with limit rods slidably connected to the slot plate.
[0008] Both ends of the first adjustment plate and the second adjustment plate are respectively provided with mounting slot blocks, the magnetic columns are detachably installed between the mounting slot blocks, and both ends of the first adjustment plate and the second adjustment plate are respectively provided with sliding pins slidably connected to the inner wall of the support plate.
[0009] A plurality of grooves are evenly arranged on the base, and a plurality of through holes corresponding to the grooves are evenly opened on the upper limit plate.
[0010] The utility model has novel structure, ingenious design, simple and convenient operation, and has the following advantages compared with the existing technology:
[0011] The first adjustment plate and the second adjustment plate move toward each other to adjust the positions of the mounting shaft blocks at both ends of the first adjustment plate and the second adjustment plate. Since the magnetic column is set on the mounting shaft block, the position of the magnetic column can be adjusted by changing the position of the first adjustment plate and the second adjustment plate, which effectively solves the problem that the magnetic position of the magnetic frame is single and the magnetic attraction range is lower, and when processing experiments with a large amount of single samples, there will be uneven elution, resulting in sample waste.

DETAILED DESCRIPTION
[0017] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0018] like Figure 1-4As shown, a new type of magnetic rack comprises a base 2, a support plate 1 is provided at one end of the base 2, an upper limit plate 3 is fixedly connected to the upper end of the support plate 1, a number of test tubes 4 are evenly arranged in the base 2 and the upper limit plate 3, a position adjustment structure is provided on the support plate 1, and the position adjustment structure includes a slot plate 7 slidably connected to the support plate 1, a pair of inclined slots 10 are symmetrically provided at both ends of the slot plate 7, and a first positioning plate 13 and a second positioning plate 14 slidably connected to the support plate 1 are provided at one end of the test tube 4, a fixing pin 18 is respectively provided on the first positioning plate 13 and the second positioning plate 14 and is limitedly slidably connected to the inclined slot 10, and a magnetic column 15 corresponding to the test tube 4 is also provided on the first positioning plate 13 and the second positioning plate 14.
[0019] When the present invention is in use, the test tube 4 is respectively arranged between the base 2 and the upper limit plate 3. According to the length of the test tube 4, the position adjustment structure is controlled to work, and the slot plate 7 slides along the surface of the support plate 1. During the sliding of the slot plate 7, the inclined slots 10 at both ends of the slot plate 7 slide through the limited position with the fixed pin 18, thereby driving the first adjustment plate 13 and the second adjustment plate 14 at one end of the fixed pin 18 to move inward, and adjust the position between the magnetic columns 15 on the first adjustment plate 13 and the second adjustment plate 14 to increase the magnetic attraction position and magnetic attraction range of the magnetic frame, effectively avoiding the phenomenon of uneven elution when processing experiments with a large amount of single samples, resulting in the problem of sample waste.
[0020] The position adjustment structure also includes a screw 8 rotatably connected to the support plate 1, a fixed shaft block 9 is provided at one end of the slot plate 7, and a screw barrel 11 threadedly connected to the screw 8 is fixedly connected to the inner wall of the fixed shaft block 9, and a limiting rod 6 slidably connected to the slot plate 7 is provided at both ends of the support plate 1.
[0021] like Figure 2 As shown, a turning handle 19 is provided at one end of the screw rod 8, and the turning handle 19 drives the screw rod 8 to rotate. During the rotation of the screw rod 8, the screw rod 8 is threadedly engaged with the screw barrel 11 in the fixed shaft block 9, thereby driving the fixed shaft block 9 to move along the axial direction of the screw rod 8. Since the fixed shaft block 9 and the slot plate 7 are fixedly connected, the slot plate 7 is driven by the fixed shaft block 9 to slide along the surface of the support plate 1, and the limiting rod 6 plays a role in limiting the movement of the slot plate 7.
[0022] Both ends of the first adjustment plate 13 and the second adjustment plate 14 are respectively provided with mounting slot blocks 5, and the magnetic columns 15 are detachably installed between the mounting slot blocks 5. Both ends of the first adjustment plate 13 and the second adjustment plate 14 are respectively provided with sliding pins 12 that are slidably connected to the inner wall of the support plate 1.
[0023] like Figure 3As shown, the first adjustment plate 13 and the second adjustment plate 14 move toward each other to adjust the position of the mounting slot blocks 5 at both ends of the first adjustment plate 13 and the second adjustment plate 14. Since the magnetic column 15 is set on the mounting slot block 5, the position of the magnetic column 15 can be adjusted by changing the position of the first adjustment plate 13 and the second adjustment plate 14, which effectively solves the problem that the magnetic position of the magnetic frame is single and the magnetic range is lower. When processing experiments with a large amount of single samples, there will be uneven elution, resulting in sample waste.
[0024] The base 2 is evenly provided with a plurality of grooves 16 , and the upper limit plate 3 is evenly provided with a plurality of through holes 17 corresponding to the grooves 16 .
[0025] like Figure 4 As shown, the test tube 4 can pass through the through hole 17 and fall into the groove 16 , and the through hole 17 and the groove 16 are used to fix the position of the test tube 4 .
[0026] The working process of the present invention is as follows: when the present invention is in use, the test tube 4 is respectively arranged between the base 2 and the upper limit plate 3, and the test tube 4 can pass through the through hole 17 and fall into the groove 16. The through hole 17 and the groove 16 are used to fix the position of the test tube 4. According to the length of the test tube 4, the screw rod 8 is driven to rotate by the rotating handle 19. During the rotation of the screw 8, the screw barrel 11 in the fixed shaft block 9 is threadedly engaged to drive the fixed shaft block 9 to move along the axial direction of the screw 8. Since the fixed shaft block 9 and the slot plate 7 are fixedly connected, the through hole 17 and the groove 16 are used to fix the position of the test tube 4. The fixed shaft block 9 drives the slot plate 7 to slide along the surface of the support plate 1. During the sliding of the slot plate 7, the inclined slots 10 at both ends of the slot plate 7 slide by limiting with the fixed pin 18, thereby driving the first adjustment plate 13 and the second adjustment plate 14 at one end of the fixed pin 18 to move inward, and adjusting the position between the magnetic columns 15 on the first adjustment plate 13 and the second adjustment plate 14 to increase the magnetic attraction position and magnetic attraction range of the magnetic frame, effectively avoiding the problem of uneven elution when processing experiments with a large amount of single samples, resulting in sample waste.
