Description

Technical Field

[0001] This invention belongs to the field of reagent kit technology, specifically to a reagent kit for gene detection and extraction. Background Technology

[0002] Gene detection extraction kits are tools for storing reagent tubes containing extracted biological samples of DNA or RNA, so that they can be transported to the laboratory for gene detection.

[0003] To ensure the stability of reagent tubes during transport and to accommodate reagent tubes of different sizes, clamping mechanisms are configured on the reagent kit. For example, patent CN217599171U discloses a biological gene detection kit for extracting microbial DNA, which includes a box body with a placement block inside. The top surface of the placement block has several placement slots. Fixing plates are symmetrically fixed on both sides above the slot openings. Two fixing plates are fixedly installed with first springs on their adjacent sides. One end of each of the two first springs is fixedly connected to a first magnet and a second magnet, respectively. Rubber pads are fixedly installed on the adjacent sides of the first magnet and the second magnet. The first magnet and the second magnet have opposite magnetic properties. This biological gene detection kit for extracting microbial DNA, by setting up fixing plates, first springs, telescopic rods, first magnets, second magnets, and rubber pads, can clamp and fix reagent tubes of different sizes, thereby keeping them stable and preventing them from colliding with the inner wall of the placement slots and causing damage.

[0004] While the aforementioned patent can better protect the reagent tubes, it requires separating the first and second magnets in each group when handling batches of reagent tubes, which is quite troublesome and increases the workload of the staff. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a reagent kit for gene detection and extraction. Pressing the transmission rod simultaneously controls all mounting seats to move downwards. During the downward movement of the mounting seats, they are restricted by the inclined first sliding groove and move to both sides, thereby increasing the distance between the two mounting seats and facilitating the operator to pick up and put down the reagent tubes. After releasing the transmission rod, the first spring drives the mounting seats upwards, and the clamps on the mounting seats clamp and fix the reagent tubes, greatly reducing the labor intensity of the operator.

[0006] The technical solution adopted in this utility model is as follows:

[0011] Preferably, the support plate has an installation groove, the lower end of the transmission rod abuts against the installation groove, and the lower end of the transmission rod is fixedly fitted with a bearing, the outer ring of the bearing abutting against the side wall of the installation groove.

[0012] Preferably, the box body is provided with a box lid, the two sides of the box lid are provided with hooks, and the box body is provided with a spring lock.

[0013] Preferably, the top outer edge of the lid is provided with a first annular notch, and the bottom of the box body is provided with a first slot.

[0014] Preferably, the top outer edge of the box body is provided with a second annular notch, and the bottom of the box lid is provided with a second slot.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] Pressing the transmission rod simultaneously controls all mounting seats to move downwards.

[0028] The following is combined Figures 1-6 This utility model will be described in detail.

[0029] Example

[0030] A reagent kit for gene detection and extraction includes a housing 1, in which a mounting block 3 is fixedly disposed. Several reagent tube placement slots 11 are vertically disposed in the mounting block 3. Clearance slots 10 are provided on both sides of each reagent tube placement slot 11. Mounting seats 16 are movably disposed within the clearance slots 10. Clamps 19 are provided on the opposite faces of the two mounting seats 16. A first sliding groove 9 is inclinedly disposed within the clearance slots 10, gradually tilting downwards towards the outer side of the reagent tube placement slots 11. A sliding device is slidably disposed on the first sliding groove 9. A first slider 15 is provided, connected to a mounting base 16. A connecting rod 17 is connected to the mounting base 16, and a second slider 4 is connected to the bottom of the connecting rod 17. A working cavity 8 is provided between the bottom of the mounting block 3 and the box body 1. A support plate 6 is movably arranged in the working cavity 8. A second sliding groove 5 is provided on the support plate 6 to cooperate with the second slider 4. The second sliding groove 5 is arranged along the direction of the two mounting bases 16 moving towards each other. A first spring 7 is connected to the bottom of the support plate 6, and a transmission rod 13 that movably passes through the mounting block 3 is connected to the support plate 6. The cooperation between the first sliding groove 9 and the first slider 15, and the cooperation between the second slider 4 and the second sliding groove 5, are both existing technologies. The slider can only slide in the groove and cannot disengage from the groove.

[0031] The clearance groove 10 contains a movable mounting base 16, and clamps 19 are mounted on the opposite surfaces of the mounting bases 16. The clamps 19 play an important role when it is necessary to fix or release the reagent tube 100. It is worth noting that the clearance groove 10 also has a specially designed inclined first slide groove 9. This layout causes not only vertical displacement but also horizontal position change as the first slider 15 slides along the first slide groove 9, thereby changing the distance between the two mounting bases 16.

[0032] This device also includes a complex linkage mechanism: the mounting base 16 is connected to the support plate 6 located in the working chamber 8 via a connecting rod 17. The working chamber 8 is a space located between the mounting block 3 and the bottom of the housing 1, in which the support plate 6 is movably mounted. A second groove 5 is formed on the support plate 6, specifically designed to match the movement trajectory of the second slider 4, which is one of the components fixed to the bottom of the connecting rod 17. This design ensures that even during complex movements, the various components can cooperate smoothly without jamming.

[0033] The operator presses the transmission rod 13, which pushes the support plate 6 downward and compresses the first spring 7. The support plate 6 pulls all the mounting seats 16 downward through the second slider 4 and the connecting rod 17. The mounting seats 16 also move horizontally under the constraint of the first sliding groove 9 and the first slider 15, thereby increasing the distance between the two mounting seats 16, making it easier for the operator to pick up and put down the reagent tube 100. After the reagent tube 100 is placed, the transmission rod 13 is released, and the first spring 7 drives the mounting seat 16 upward. The clamp 19 on the mounting seat 16 clamps and fixes the reagent tube 100, greatly reducing the labor intensity of the operator.

[0034] Furthermore, to achieve the automatic reset function, a first spring 7 is installed below the support plate 6. This spring 7 quickly returns to its original shape after the external pressure is released, driving the entire mechanism back to its initial state. More importantly, to facilitate pressing operations, a circular handle is installed at the top of the transmission rod 13, allowing for easier and more accurate application of the required force. Additionally, considering that the connecting rod 17 needs sufficient space to complete horizontal displacement, a through slot 18 is specifically provided at the bottom of the mounting block 3.

[0035] The clamp 19 includes a guide groove 191 formed on the mounting base 16. A guide block 193 is movably disposed in the guide groove 191. A second spring 192 is connected to the tail end of the guide block 193, and an arc-shaped clamping plate 195 is connected to the front end of the guide block 193. The arc-shaped clamping plate 195 can automatically adjust its position according to the size of the reagent tube 100 in cooperation with the guide block 193 and the second spring 192, thereby clamping reagent tubes 100 of different sizes and ensuring the stability of the second spring 192; the second spring 192 also plays a role in shock absorption.

[0036] A rubber pad 194 is provided on the side of the arc-shaped clamp 195 away from the guide block 193. The rubber pad 194 can increase the friction between the arc-shaped clamp 195 and the reagent tube 100, prevent the reagent tube 100 from slipping, and also prevent the reagent tube 100 from being damaged by the arc-shaped clamp 195.

[0037] The transmission rod 13 is rotatably connected to the support plate 6. A stop bar 14 is horizontally fixed on the transmission rod 13. An L-shaped groove 12 is provided on the mounting block 3 to cooperate with the stop bar 14 and restrict the upward movement of the transmission rod 13. When the transmission rod 13 is pressed down, it is difficult to maintain the pressed state manually. Therefore, the L-shaped groove 12 is provided to cooperate with the stop bar 14 on the transmission rod 13 to lock the transmission rod 13. That is, during the pressing of the transmission rod 13, the stop bar 14 slides along the vertical part of the L-shaped groove 12. Then, the transmission rod 13 is rotated to move the stop bar 14 to the horizontal part of the L-shaped groove 12, thereby restricting the upward movement of the transmission rod 13.

[0038] Two stop levers 14 can be provided, located on both sides of the transmission rod 13 respectively. Correspondingly, two L-shaped grooves 12 are also provided, so that the force on the transmission rod 13 is more even.

[0039] A mounting groove 21 is provided on the support plate 6. The lower end of the transmission rod 13 is a ball head that abuts against the mounting groove 21. A bearing 20 is fixedly sleeved on the lower end of the transmission rod 13. The lower end face of the bearing 20 does not contact the bottom of the mounting groove 21, and the outer ring of the bearing 20 abuts against the side wall of the mounting groove 21. By providing a mounting groove 21 on the support plate 6, the ball head of the lower end of the transmission rod 13 can abut against the mounting groove 21. The bearing 20 is fixedly sleeved on the lower end of the transmission rod 13, and the lower end face of the bearing 20 does not contact the bottom of the mounting groove. This design aims to reduce friction during the movement of the transmission rod 13, thereby improving transmission efficiency and stability. The abutment of the outer ring of the bearing 20 against the side wall of the mounting groove 21 ensures that the movement direction of the transmission rod 13 remains consistent and avoids deviation. The ball head design of the transmission rod 13 reduces the friction between the transmission rod 13 and the mounting groove 21, facilitating rotation. The transmission rod 13 contacts the support plate 6 through the ball head and transmits pressure to the support plate 6, while the bearing 20 does not bear the pressing force, but only maintains the rotatability of the transmission rod 13.

[0040] The box body 1 is provided with a box lid 2, and hooks 206 are provided on both sides of the box lid 2. The box body 1 is provided with a spring lock 101 that cooperates with the hooks 206. The hooks 206 and the spring lock 101 cooperate to detachably connect the box lid 2 to the box body 1, effectively protecting the reagent tube 100 inside the box body 1.

[0041] The spring-loaded latch 101 includes the following structure: Outer shell: typically made of metal or high-strength plastic, used to secure the internal components of the latch. Hook: a movable part that engages with the corresponding hook 206 via the spring's elasticity to achieve locking. Spring: the core component, providing elasticity to keep the latch in the locked state; when the release button is pressed, the spring is compressed, and the latch retracts. Release button / pull ring: a manually operated part that unlocks the latch by pressing or pulling. When the spring-loaded latch 101 is locked, the spring is in its naturally extended state, and the latch is pushed out by the elasticity, engaging with the hook 206 to form a mechanical lock. During the unlocking process of the spring-loaded latch 101, pressing the release button or pulling the pull ring compresses the spring, causing the latch to retract and disengage from the lock groove, thus releasing the lock.

[0042] The top outer edge of the lid 2 is provided with a first annular notch 205, and the bottom of the box body 1 is provided with a first slot 102 that mates with the first annular notch 205. The first annular notch 205 on the lid 2 can be inserted into the first slot 102 at the bottom of another box body 1, so that the two reagent kits can be placed stably one above the other.

[0043] The top of the lid 2 has a receiving groove 203, in which a flexible handle 202 is installed. Both ends of the flexible handle 202 are connected to sliding rods 201. The side wall of the receiving groove 203 has a third sliding groove 204 for the sliding rods 201 to slide. The receiving groove 203 at the top of the lid 2 provides an embedding space for the flexible handle 202, allowing it to be stored in the receiving groove 203 when not in use. The sliding rods 201 connect to both ends of the flexible handle 202, allowing it to slide within the receiving groove 203. The third sliding groove 204 on the side wall of the receiving groove 203 allows the sliding rods 201 to slide within the third sliding groove 204, making it easy to pull out or retract the flexible handle 202. The design of the flexible handle 202 provides a convenient way to lift the lid 2 and the box body 1; the operator can easily lift the lid 2 and the box body 1 by pulling out the flexible handle 202. The design of the slide bar 201 and the third slide groove 204 ensures smooth operation of the flexible handle 202 when pulled out or retracted. Furthermore, the flexible handle 202 is made of rubber, providing a comfortable feel and anti-slip effect. This application provides a convenient and comfortable extraction method by providing a receiving groove 203 and a flexible handle 202 on the top of the lid 2. The design of the slide bar 201 and the third slide groove 204 ensures smooth sliding of the flexible handle 202, further improving the convenience of operation and user experience. When stacking reagent kits, the flexible handle 202 can slide to both sides via the slide bar 201 and be stored in the receiving groove 203, ensuring the flatness of the upper surface of the lid 2, thus ensuring that the reagent kits can be stacked stably.

[0044] The top outer edge of the box body 1 is provided with a second annular notch 103, and the bottom of the box cover 2 is provided with a second slot 207 that mates with the second annular notch 103. The second annular notch 103 mates with the second slot 207, so that the box body 1 and the box cover 2 can be stably locked and connected into a whole, avoiding the situation where the box cover 2 becomes loose or falls off due to collision or vibration.
