[0002] Reagent tubes are used to hold liquid reagents, and they need to be positioned or moved after being filled with reagents. Currently, there are reagent kits or reagent tube racks, but the diameters of the reagent tubes vary. When a smaller reagent tube is placed into the mounting hole on a larger reagent rack, it can cause the tube to wobble and shift its position, making it difficult to ensure the tube's proper placement. Utility Model Content
[0003] To address the shortcomings of the existing technology, this invention proposes a chemical reagent tube placement assembly.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A chemical reagent tube placement assembly, characterized in that it comprises:
[0006] A base, wherein an installation chamber is formed in the middle of the base, and a cover plate is provided on the base, wherein an insertion hole is provided on the cover plate;
[0007] A retainer is installed in the installation chamber. The retainer has a fixing section, and the installation chamber has a fixing groove that mates with the fixing section. The retainer also has a retaining hole for inserting a reagent tube. The lower end of the retaining hole has a retaining arm that applies pressure to the reagent tube.
[0008] The mounting chamber is equipped with a rotating component that mates with the retaining component. The rotating component is mounted on the base via a rotating rod. When the rotating component rotates, its lower end pushes the retaining arm, causing the lower end of the retaining hole to open.
[0009] In this chemical reagent tube placement assembly of the present invention, the retaining member is composed of a transverse section and an inclined section, the retaining hole is provided on the transverse section, the transverse section is provided with a first arc-shaped portion, the retaining hole is provided with a second arc-shaped portion, and a rotation area that cooperates with the rotating rod is formed between the first arc-shaped portion and the second arc-shaped portion.
[0010] In this chemical reagent tube placement assembly of the present invention, the inclined section is provided with a punching hole, and the fixing section is disposed in the punching hole.
[0011] In this chemical reagent tube placement assembly of the present invention, the inclined section and the retaining arm are connected by a third arc-shaped portion, and an elastic region is formed between the inclined section and the retaining arm.
[0012] In this chemical reagent tube placement assembly of the present invention, the retaining arm is provided with a contact section, the contact section and the retaining arm are connected by a fourth arc-shaped part, the contact section is provided with an arc-shaped segment in the middle, and the arc-shaped opening that mates with the reagent tube is formed in the middle of the arc-shaped segment, and the arc-shaped opening is located at the lower end of the retaining hole and the insertion hole.

[0014] The chemical reagent tube placement assembly of this utility model has the following beneficial effects: The assembly uses a retaining member to apply pressure and limit the position of the reagent tube. Simultaneously, before inserting the reagent tube, a rotating member needs to be rotated, thereby causing the retaining arm on the retaining member to deform under force. Through the cooperation of the retaining arm and the second arc-shaped part, reagent tubes of different diameters can be clamped, ensuring that reagent tubes of different diameters do not wobble when placed in the retaining hole. This prevents the reagent tube from shifting position in the retaining hole during transfer of the placement assembly, thus avoiding liquid spillage and improving the stability of the reagent tube position.

[0024] 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.
[0025] like Figures 1 to 9 As shown, this chemical reagent tube placement assembly of the present invention includes a base 1, a retaining member 2, and a rotating member 3. The retaining member 2 and the rotating member 3 are disposed in the middle of the base 1. The retaining member 2 is used to restrict the position of the reagent tube, while the rotating member 3 is used to push the retaining arm 4 on the retaining member 2 to deform under force, facilitating the insertion of the reagent tube. Then, the elastic force of the retaining arm 4 pushes the rotating member 3 to reset, and applies pressure to position the reagent tube placed in the retaining hole 5, thus restricting the position of the reagent tube.
[0026] A mounting chamber 6 is formed in the middle of the base 1. A cover plate 7 is provided on the base 1. The cover plate 7 can be fixed to the base 1 with screws. An insertion hole 8 is provided on the cover plate 7. A notch 9 is provided at one end of the mounting chamber 6 to facilitate the rotation of the rotating part 3. Thus, the rotating part 3 pushes the retaining arm 4 on the retaining part 2 to deform.
[0027] The retainer 2 is disposed in the mounting chamber 6. The retainer 2 has a fixing section 10 and a punching hole 12 on the inclined section 11. The fixing section 10 is disposed in the punching hole 12. The mounting chamber 6 has a fixing groove 13 that mates with the fixing section 10. The retainer 2 also has a retaining hole 5 for inserting a reagent tube. The lower end of the retaining hole 5 has a retaining arm 4, which applies pressure to the reagent tube.
[0028] The retainer 2 consists of a transverse section 14 and an inclined section 11. A retaining hole 5 is provided on the transverse section 14. A first arcuate portion 15 is provided on the transverse section 14, and a second arcuate portion 16 is provided inside the retaining hole 5. A rotation area 18 is formed between the first arcuate portion 15 and the second arcuate portion 16 to cooperate with the rotating rod 17. The position of the retainer 2 is restricted by the cooperation of the fixed section 10, the first arcuate portion 15, and the second arcuate portion 16.
[0029] The inclined section 11 and the retaining arm 4 are connected by a third arc-shaped portion 19, forming an elastic region 20 between them. The third arc-shaped portion 19 is placed on the bottom wall of the mounting chamber 6. When the rotating member 3 pushes the retaining arm 4, the retaining arm 4 moves towards the inclined section 11, compressing the elastic region 20, and causing the third arc-shaped portion 19 to slide on the bottom wall of the mounting chamber 6. Since the fixed section 10 is inserted into the fixed groove 13 and its position remains unchanged, after the inclined section 11 moves a small distance, its position becomes fixed, causing the retaining arm 4 to gradually deform under force and generate elastic potential energy.
[0030] The retaining arm 4 is provided with a contact section 21, which is connected to the retaining arm 4 through a fourth arc-shaped part 22. The contact section 21 is provided with an arc-shaped section 23 in the middle, and an arc-shaped opening 24 that mates with the reagent tube is formed in the middle of the arc-shaped section 23. The arc-shaped opening 24 is located at the lower end of the retaining hole 5 and the insertion hole 8.
[0031] A compression region 25 is formed between the contact section 21 and the retaining arm 4. When the reagent tube is inserted into the mounting chamber 6 through the insertion hole 8 and the retaining hole 5, the bottom of the reagent tube can push the contact section 21 to deform it, and the compression region 25 shrinks. The reagent tube is held by the clamping region 26 located between the second arcuate portion 16 and the contact section 21.
[0032] The mounting chamber 6 is equipped with a rotating component 3 that cooperates with the retaining component 2. The rotating component 3 is mounted on the base 1 via a rotating rod 17. When the rotating component 3 rotates, it pushes the retaining arm 4 through the lower end of the rotating component 3, causing the lower end of the retaining hole 5 to open.
[0033] The rotating component 3 is provided with a rotating ring 27, and a hinge hole 28 is formed in the middle of the rotating ring 27 to cooperate with the rotating rod 17. The lower end of the rotating component 3 is provided with symmetrically arranged push plates 29, which are located on both sides of the holding hole 5. A receiving area 291 for inserting a reagent tube is formed between the push plates 29 and the push plates 29.
[0034] Additionally, the rotating rod 17 can be set to a longer length according to actual needs, connecting multiple bases 1 together to achieve the assembly of multiple bases 1, which is beneficial for placing multiple reagent tubes.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
