Description

Technical Field

[0001] This invention relates to the field of PCR kit technology, and more particularly to an adjustment device for PCR kits based on multi-size test tubes. Background Technology

[0002] Existing reagent kits typically have fixed reagent tube racks that can only hold tubes of a single diameter. Furthermore, the depth of the reagent slots in existing kits is fixed, preventing the placement of tubes of varying heights. This undoubtedly increases the limitations of the kits. In addition, the clamping mechanisms in existing kits usually use two clamping plates to hold and secure the tubes. However, if the two clamping plates clamp the tubes too tightly, it can damage them and make it difficult to insert or remove them. If the clamping plates do not clamp the tubes tightly, they can cause them to wobble within the slots, making it impossible to stably store them within the kit. This also undoubtedly increases the limitations of the kits.

[0003] A regulating device for a PCR kit and a PCR kit, disclosed in publication number CN114803086B, are described. The regulating device includes a support unit, a support unit, several clamping units, two driving units, and a driving unit. The support unit supports the lower end of the reagent tube; the support unit is positioned above the support unit and corresponds vertically to it, and is used to accommodate the upper end of the reagent tube; several clamping units are slidably fitted onto both sides of the support unit, and are used to clamp and fix the upper end of the reagent tube; the two driving units are slidably connected laterally to both ends of the support unit, and are used to drive the support unit to reciprocate vertically; the two ends of the driving unit are respectively connected to the two driving units for transmission, and are used to drive the support unit to reciprocate vertically. This invention has a simple and reasonable structure, solving the problems of existing kits being unable to store reagent tubes of different diameters and heights, and the limitations of existing clamping structures within the kits.

[0004] The above technical solution can effectively adapt to test tubes of various sizes. However, in actual operation, it can only adapt to one size of test tube at a time and cannot adapt to multiple sizes of test tubes simultaneously. At the same time, it cannot effectively achieve the mixing of materials in the test tubes, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustment device for a PCR kit based on multi-size test tubes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustment device for a PCR kit based on multi-size test tubes includes a box assembly, a sealing plate hinged to one side of the upper end of the box assembly, and an I-shaped ring piece detachably connected inside the sealing plate.

[0008] A rubber connector is fixed to the lower end of the I-shaped ring component, and a stainless steel box is inserted into the lower end of the rubber connector. The stainless steel box is located inside the box assembly, and a vibration component is installed at the bottom inside the box assembly. The vibration component is connected to the stainless steel box.

[0009] A control component is installed on one side of the housing assembly, and the control component is connected to the vibration component;

[0010] The stainless steel box contains a test tube insertion plate. Multiple fixing clips are fixed at equal intervals on both ends of one side of the test tube insertion plate. The test tube insertion plate is equipped with a rotating mechanism. The rotating mechanism has two sliding plates, which share a sliding mechanism. The sliding plates are equipped with an adaptation mechanism, which has multiple screws. One end of each screw is fixed with a movable clip, and each movable clip corresponds to one of the multiple fixing clips.

[0011] Compared with the prior art, the present invention can effectively adapt to test tubes of various sizes, simultaneously clamp test tubes of various sizes, and effectively protect the test tubes to avoid external influences; at the same time, it can control the stainless steel box to drive the test tubes inside to vibrate, so that the reagents inside the test tubes can be vibrated and mixed.

[0012] Preferably, the box assembly has notches on both sides, a pressure plate is rotatably connected in the notch, and an abutment plate is slidably installed in the notch. The upper end of the abutment plate abuts against the lower end of the notch, and the lower end of the pressure plate abuts against the upper end of the I-shaped ring. The I-shaped ring has mounting openings on both sides, and a positioning mechanism is provided in the mounting opening. The positioning mechanism has a push plate and an L-shaped plate. The L-shaped plate is located on one side of the rubber connector and the stainless steel box body. One end of the push plate abuts against a limit plate, and the limit plate and the abutment plate are fixedly connected.

[0013] Furthermore, the operation of the positioning mechanism allows the push plate to abut against the limiting plate, which in turn moves the lower end of the notch, causing the notch to rotate. The rotation of the notch abuts against the upper end of the I-shaped ring, effectively limiting the position of the I-shaped ring and preventing it from moving upward.

[0014] Preferably, connecting plates are fixed on both the inner and outer walls of the upper end of the stainless steel box, and the connecting plates are disposed through the rubber connector.

[0015] Furthermore, the rubber connector is flexible, which makes it easy for the connecting plates on the stainless steel box to be inserted into the corresponding positions and to make effective contact with the stainless steel box. When vibration occurs, the movement of the stainless steel box is transmitted to the rubber connector, which can effectively isolate the vibration and stabilize the box assembly and sealing plate.

[0016] Preferably, the lower end of the L-shaped plate extends into the stainless steel box body, and a positioning rod is fixed to the lower end of the L-shaped plate. The positioning rod passes through the I-shaped ring and the rubber connector and extends into the rubber connector.

[0017] Furthermore, the movement of the L-shaped plate allows the positioning rod to pass through the I-shaped ring and the rubber connector. The rubber connector can also reduce vibration transmission and effectively ensure the stability of the rubber connector's position, thus ensuring the stability of the stainless steel box.

[0018] Preferably, the positioning mechanism includes an opening that is slidably installed in the mounting port, with fixing plates fixed on both sides of the opening, a plug rod that is slidably sleeved in the fixing plate, a spring that is sleeved on the plug rod, and the two ends of the spring that are fixed to the plug rod and the opening respectively. Insertion holes are provided on opposite side walls of the mounting port, and the two openings extend into the two insertion holes respectively.

[0019] Furthermore, the operator can move the insertion rod by squeezing the spring component, thereby pushing the opening to move. When the insertion rod aligns with the insertion hole, it can be inserted into the hole, defining the position of the opening. The movement of the opening can also drive the corresponding component to operate, causing the pressure plate to flip.

[0020] Preferably, the lower end of the push plate abuts against the bottom of the notch.

[0021] Furthermore, the push plate prevents the I-shaped ring from moving downwards, and the pressure plate prevents the I-shaped ring from rising, effectively limiting the position of the I-shaped ring to ensure the stability of the stainless steel box.

[0022] Preferably, the rotating mechanism includes a column fixed to the middle of one side of the test tube insertion plate, a rocker arm rotatably sleeved on the column, a knob installed on the rocker arm, and sliding members rotatably connected to both ends of the rocker arm, with the two sliding members respectively slidably sleeved on two sliding plates.

[0023] Furthermore, the knob allows the lever to control the sliding component, which in turn moves the slide plate to separate the fixed frame and the moving clamp, facilitating the clamping of the test tube later.

[0024] Preferably, the sliding mechanism includes four sliding sleeves that are respectively disposed through both ends of the two sliding plates, and a U-shaped rod is slidably sleeved on the two sliding sleeves on the same side. The U-shaped rod is fixedly connected to the test tube insertion plate.

[0025] Furthermore, the U-shaped bar ensures that the skateboard can move smoothly.

[0026] Preferably, the adaptation mechanism includes a plurality of first springs fixed to one side of the slide plate, a plurality of screws respectively sleeved in the plurality of first springs, the lower end of the first springs being fixed to one end of the screws, and a nut being screwed onto the screw, the nut being located on the side of the slide plate away from the first springs.

[0027] Furthermore, by rotating the nut, the screw can move stably along the slide plate, which in turn drives the movable clamp fixed to it to move towards the corresponding fixed clamp, so as to clamp the test tube. At the same time, by adjusting the distance between the movable clamp slide plate, it can accommodate test tubes of various sizes, so as to achieve the purpose of clamping test tubes of different sizes simultaneously.

[0028] Preferably, a second spring is fixed between the two slide plates; one end of both the fixed clamp and the movable clamp is arc-shaped.

[0029] Furthermore, the second spring can push the two slides to separate and move when no external force is applied, so that the moving clamp on the slide can move towards the corresponding fixed clamp, so that the moving clamp and the fixed clamp can firmly clamp the test tube.

[0030] The beneficial effects of this invention are:

[0031] 1. The operator can move the insertion rod by squeezing the spring component, thereby pushing the opening to move. When the insertion rod aligns with the insertion hole, it can be inserted into the insertion hole, limiting the position of the opening. The movement of the opening can drive the corresponding component to operate, causing the push plate to abut against the limiting plate. This causes the abutting plate to move against the lower end of the notch, causing the notch to rotate. The rotation of the notch can abut against the upper end of the I-shaped ring component, effectively limiting the position of the I-shaped ring component and preventing it from moving upward.

[0032] 2. The rubber connector is flexible, allowing the connecting plate on the stainless steel box to be easily inserted into the corresponding position and to effectively contact the stainless steel box. During vibration, the movement of the stainless steel box is transmitted to the rubber connector, effectively isolating vibration and stabilizing the box assembly and sealing plate. The movement of the L-shaped plate allows the positioning rod to pass through the I-shaped ring and the rubber connector. The rubber connector can also reduce vibration transmission and effectively ensure the stability of the rubber connector's position installation without affecting the vibration of the stainless steel box, thus ensuring the quality of the connection between the stainless steel box and the rubber connector.

[0033] 3. By connecting the control component and the vibration component, the control component can control the operation of the vibration component to make the stainless steel box vibrate, which helps to drive the test tube to vibrate so that the materials in the test tube can be mixed.

[0034] 4. The knob can be used to adjust the lever, which allows the slider to move the two slides relative to each other, moving the moving clamp away from the fixed clamp for easier placement of test tubes; the second spring can effectively push the slide back to its original position, allowing the moving clamp to move towards the fixed clamp and clamp the test tubes; it is suitable for test tubes of various sizes.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

In actual production and preparation, a corresponding elastic hinge device is installed between the sealing plate 1 and the box assembly 2 to help ensure that the sealing plate 1 and the box assembly 2 can rotate and close as needed. An I-shaped ring 4 is detachably connected inside the sealing plate 1, which can quickly complete the installation and disassembly of the I-shaped ring 4 and ensure the firmness of the connection between the I-shaped ring 4 and the box assembly 2.

[0047] In this embodiment, notches 8 are provided on both sides of the box assembly 2. A pressure plate 3 is rotatably connected within the notch 8, and an abutment plate 9 is slidably installed within the notch 8. The upper end of the abutment plate 9 abuts against the lower end of the notch 8. The lower end of the pressure plate 3 abuts against the upper end of the I-shaped ring 4. Mounting openings 17 are provided on both sides of the I-shaped ring 4. A positioning mechanism is provided within the mounting opening 17. The positioning mechanism is equipped with a push plate 16 and an L-shaped plate. The L-shaped plate is located between the rubber connector 5 and the stainless steel... On one side of the box body 6, one end of the push plate 16 abuts against the limiting plate 15, and the limiting plate 15 and the abutting plate 9 are fixedly connected; the lower end of the push plate 16 abuts against the bottom of the notch 8; during actual production, the operation of the positioning mechanism can make the push plate 16 abut against the limiting plate 15, and can make the abutting plate 9 abut against the lower end of the notch 8 and move, causing the notch 8 to rotate. The rotation of the notch 8 can abut against the upper end of the I-shaped ring part 4, effectively limiting the position of the I-shaped ring part 4 and preventing it from moving upward.

[0048] In this embodiment, the positioning mechanism includes an opening 14 slidably installed in the mounting port 17. Fixing plates 13 are fixed to both sides of the opening 14. An insert rod 11 is slidably sleeved within the fixing plates 13. A spring 12 is sleeved on the insert rod 11, with both ends of the spring 12 fixed to the insert rod 11 and the opening 14, respectively. Insertion holes 10 are provided on opposite sidewalls within the mounting port 17, and the two openings 14 extend into the two insertion holes 10. The operator can move the insert rod 11 by squeezing it, causing it to press against the spring 12, thereby pushing the opening 14 to move. When the insert rod 11 aligns with the insertion hole 10, it can be inserted into the insertion hole 10, thus defining the position of the opening 14. Furthermore, the movement of the opening 14 can drive the corresponding component to operate, causing the pressure plate 3 to flip.

[0049] In this embodiment, a rubber connector 5 is fixed to the lower end of the I-shaped ring 4, and a stainless steel box 6 is inserted into the lower end of the rubber connector 5. Connecting plates 18 are fixed to the inner and outer walls of the upper end of the stainless steel box 6. The connecting plates 18 are disposed through the rubber connector 5. The lower end of an L-shaped plate extends into the stainless steel box 6, and a positioning rod 19 is fixed to the lower end of the L-shaped plate. The positioning rod 19 passes through the I-shaped ring 4 and the rubber connector 5 and extends into the rubber connector 5. The stainless steel box 6 is located inside the box assembly 2, and a vibration assembly 7 is installed at the bottom of the box assembly 2. The vibration assembly 7 is connected to the stainless steel box 6. The rubber connector 5 has a flexible... The L-shaped plate allows the connecting plate 18 on the stainless steel box 6 to be inserted into the corresponding position and to make effective contact with the stainless steel box 6. When vibration occurs, the movement of the stainless steel box 6 is transmitted to the rubber connector 5, which can effectively isolate vibration and stabilize the box assembly 2 and the sealing plate 1. The movement of the L-shaped plate allows the positioning rod 19 to pass through the I-shaped ring 4 and the rubber connector 5. The rubber connector 5 can reduce the transmission of vibration and effectively ensure the stability of the rubber connector 5's position installation without affecting the vibration of the stainless steel box 6, and also ensure the stability of the connection between the stainless steel box 6 and the rubber connector 5.

[0050] In this embodiment, a control component 20 is installed on one side of the box assembly 2, and the control component 20 is connected to the vibration component 7. By connecting the control component 20 and the vibration component 7, the control component 20 can control the operation of the vibration component 7 so that the stainless steel box 6 can vibrate.

[0051] In this embodiment, a test tube insertion plate 21 is installed inside the stainless steel box 6. Multiple fixing clips 22 are fixed at equal intervals on both ends of one side of the test tube insertion plate 21 to ensure the connection is firm. The test tube insertion plate 21 is provided with a rotating mechanism, and the rotating mechanism is provided with two sliding plates 27. The position of the two sliding plates 27 can be adjusted well by the rotating mechanism to facilitate the movement of the moving clip 23. The two sliding plates 27 are provided with a sliding mechanism to ensure that the sliding plates 27 can move smoothly. The sliding plates 27 are provided with an adaptation mechanism, and the adaptation mechanism is provided with multiple screws 28. One end of the screw 28 is fixed with a moving clip 23. The multiple moving clips 23 correspond one-to-one with the multiple fixing clips 22. The adaptation mechanism can improve the applicability of the product and better clamp the test tubes.

[0052] In this embodiment, the rotating mechanism includes a column 34 fixed to the middle of one side of the test tube insertion plate 21. A swing rod 31 is rotatably sleeved on the column 34. A knob 32 is installed on the swing rod 31. Sliding members 25 are rotatably connected to both ends of the swing rod 31. The two sliding members 25 are respectively slidably sleeved on two sliding plates 27. The operator drives the swing rod 31 to rotate through the knob 32. The swing rod 31 pulls the two sliding plates 27 to move relative to each other through the sliding members 25, which can separate the moving clamp 23 and the fixed clamp 22. In actual production, bolts can be added to the swing rod 31 so that the bolts can abut against the test tube insertion plate 21 so that the position of the swing rod 31 is fixed.

[0053] In this embodiment, the sliding mechanism includes four sliding sleeves 33 that are respectively disposed through both ends of the two sliding plates 27. A U-shaped rod 24 is slidably sleeved on the two sliding sleeves 33 on the same side. The U-shaped rod 24 is fixedly connected to the test tube insertion plate 21, which can ensure the stability of the movement of the sliding plate 27.

[0054] In this embodiment, the adaptation mechanism includes multiple first springs 29 fixed to one side of the slide plate 27, and multiple screws 28 respectively sleeved in the multiple first springs 29. The lower end of the first spring 29 is fixed to one end of the screw 28. A nut 26 is screwed onto the screw 28. The nut 26 is located on the side of the slide plate 27 away from the first spring 29. The first spring 29 can extend and retract to adapt to the movement of the screw 28. After adjustment, the nut 26 is rotated so that the nut 26 and the slide plate 27 abut against each other to fix the position of the moving clamp 23, ensuring the firmness of the test tube clamp, thereby achieving the purpose of simultaneously accommodating test tubes of various specifications.

[0055] In this embodiment, a second spring 30 is fixed between the two sliding plates 27, which can adapt to the movement of the sliding plates 27 and facilitate the quick reset of the sliding plates 27; one end of the fixed clamp 22 and the movable clamp 23 are both arc-shaped, which can quickly correspond to the test tube and facilitate the quick clamping and fixing of the test tube. In actual operation, the movable clamp 23 and the fixed clamp 22 are relatively long and can clamp at least half of the test tube.

[0056] In this invention, the operator rotates the lever 31 by turning the knob 32. The lever 31 pulls the two slide plates 27 relative to each other through the sliding member 25, which can separate the moving clamp 23 and the fixed clamp 22. After the fuse box is placed, the knob 32 is released. Under the action of the second spring 30, the slide plate 27 pushes the moving clamp 23 towards the fixed clamp 22 to clamp the fuse box. At the same time, the first spring 29 can extend and retract to adapt to the movement of the screw 28. After the adjustment is completed, the nut 26 is turned so that the nut 26 and the slide plate 27 abut against each other to fix the position of the moving clamp 23 and ensure the firmness of the test tube clamp.

[0057] By connecting the control component 20 and the vibration component 7, the vibration component 7 can be made to operate. The vibration component 7 can make the test tube inside the stainless steel box 6 vibrate back and forth, which can make the materials inside vibrate and mix, so as to improve the reaction efficiency and facilitate the PCR reagent detection reaction.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
