A gene sequencing kit

Abstract

This utility model discloses a gene sequencing reagent kit, including a box body, a cover plate, and a detachable placement plate. The lower end of the placement plate is equipped with an elastic clamping mechanism, consisting of three conical clamping plates and a support plate with a spindle-shaped guide roller, enabling automatic clamping upon test tube insertion and effortless insertion and removal. The bottom of the box body has a fixed base, which, through an interference fit of a strip-shaped protrusion within an annular ring, forms a double fixation with the upper clamping mechanism. This solves the problems of cumbersome operation and unstable fixation in existing technologies, making it suitable for efficient and safe handling of gene sequencing samples.

Description

Technical Field

[0001] This utility model relates to the field of gene sequencing technology, specifically a gene sequencing kit. Background Technology

[0002] During gene sequencing, the test tubes in the gene sequencing kit may become unstable after being removed from the kit, and external contact can cause them to shake, resulting in sample spillage. Existing gene sequencing kits, such as CN202321769685.7, use a lever-spring mechanism to drive a clamp to fix the test tubes, solving the problem of test tube shaking and sample spillage. However, they still have significant drawbacks: cumbersome operation, requiring manual pulling of the clamp to place / remove the test tubes, which is inconvenient for both hands; and insufficient stability, relying only on a single point of clamping, with no fixation at the bottom of the test tube, making it prone to shaking.

[0003] In view of the above-mentioned problems, the present invention aims to provide a reagent kit that can be operated with one hand, has double fixation, and is easy to insert and remove. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a gene sequencing kit, comprising:

[0005] The box body and a cover plate rotatably connected to the box body; a placement plate, detachably disposed in the middle layer of the inner cavity of the box body, the placement plate having test tube placement holes; an elastic clamping mechanism, fixedly disposed on the lower end face of the placement plate and disposed around the test tube placement holes, for clamping test tubes inserted into the test tube placement holes; a test tube placement slot, disposed at the bottom of the inner cavity of the box body; and a fixed base, disposed in the test tube placement slot, for fixing the bottom of test tubes inserted into the test tube placement slot.

[0006] As a preferred embodiment of this utility model, the elastic clamping mechanism includes a conical clamping plate, which is fixedly arranged around the test tube placement hole and is set at equal intervals of three; the minimum diameter of the hole formed by the bottom of the conical clamping plate is smaller than the diameter of the test tube, and the conical clamping plate clamps the test tube through elastic deformation.

[0007] As a preferred embodiment of this utility model, the elastic clamping mechanism further includes a support plate and a guide roller. The support plate is integrally formed on the bottom of the conical clamping plate. A square groove is formed in the middle of the support plate along its width direction. The guide roller is disposed in the square groove and rotatably connected to the support plate. The guide roller is used to convert the sliding friction between the test tube and the conical clamping plate into rolling friction when the test tube is inserted or removed.

[0008] As a preferred embodiment of this utility model, the guide roller is configured as a spindle-shaped structure that is thicker on both sides and thinner in the middle, so as to better fit the surface of the test tube.

[0009] As a preferred embodiment of this utility model, the fixed base is made of elastic material and includes an annular ring and an integrally formed annular protrusion. An annular groove is provided at the bottom edge of the test tube placement slot, and the annular ring and the annular protrusion are respectively fitted into the test tube placement slot and the annular groove.

[0010] As a preferred embodiment of this utility model, the inner circumferential surface of the annular ring is integrally formed with strip-shaped protrusions, four of which are vertically equidistant. The strip-shaped protrusions are interference-fitted with the bottom of the test tube and are used to elastically press the bottom of the test tube.

[0011] As a preferred embodiment of this utility model, the fixed base is made of rubber or silicone material, and the inner edge of the upper surface of the annular ring is set as an arc surface for easy assembly.

[0012] As a preferred embodiment of this utility model, the upper edge of the test tube placement hole is a flared conical opening to facilitate the placement of test tubes.

[0013] As a preferred embodiment of this utility model, the cover plate has an L-shaped structure with a right-angled folded edge at the front end to cover the opening of the box. This structure with an opening at the front of the box makes it easier for staff to pick up and place the box, and is more ergonomic.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] In this invention, the test tube can be directly inserted into the placement hole and elastically clamped by a conical clamping plate, eliminating the need for manual operation and making the operation more convenient. Placement / removal can be completed with one hand. The upper part is provided with radial clamping force by the conical clamping plate, and the bottom is elastically pressed by the strip-shaped protrusion to prevent shaking. The double fixation provides better stability. The spindle-shaped guide roller converts sliding friction into rolling friction, reducing insertion and extraction force by more than 30%. The flared conical round mouth guides the test tube into precise position, making insertion and extraction more effortless and accurate. Attached Figure Description

[0025] Placement plate 4: It is detachably snapped into the middle layer of the inner cavity of the box body 1, and has multiple test tube placement holes 3 evenly distributed on it. The upper edge of the test tube placement hole 3 is a flared conical opening 17 to facilitate the placement of test tubes.

[0026] Elastic clamping mechanism 5: fixed to the lower end face of the placement plate 4, and arranged around each test tube placement hole 3; elastic clamping mechanism 5 includes:

[0027] Conical clamping plates 8: Three are equidistantly arranged along the circumference of the test tube placement hole 3. The minimum diameter of the hole formed by their bottoms is smaller than the outer diameter of the test tube. The test tube is circumferentially clamped by elastic deformation.

[0028] Support plate 9: integrally formed on the bottom of the conical clamping plate 8, with a square groove 10 in the middle along the width direction;

[0029] Guide roller 11: It is rotatably connected to the square groove 10 via a rotating shaft, and has a spindle-shaped structure that is thicker at both sides and thinner in the middle, and rolls in contact with the surface of the test tube.

[0030] Test tube placement slot 6: Located at the bottom of the inner cavity of box 1, corresponding to the position of test tube placement hole 3;

[0031] Fixed base 7: Embedded in the test tube placement slot 6, used to support the bottom of the test tube;

[0032] The fixed base 7 is made of silicone material and includes:

[0033] Ring 14: Fitted into the test tube placement slot 6, with four vertically equidistant strip protrusions 16 integrally formed on the inner circumference surface, the strip protrusions 16 being interference fit with the bottom of the test tube;
