Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, and more specifically, to a reagent kit for nucleic acid extraction. Background Art

[0002] A test kit is a container for chemical reagents used to detect chemical components, drug residues, virus types, etc. It is generally used by hospitals and pharmaceutical companies. It usually processes a large number of samples in batches in order to achieve a higher sample detection processing speed.

[0003] In the prior art, after sampling is completed, the sample needs to be placed in a reagent rack, and all the reagent racks are placed in a test kit for sealing and grouping testing. During this process, when the reagent rack needs to be taken out, a raised bottom plate is usually used to push the reagent rack out so that the operator can take the required reagent rack from the test kit. However, this method causes the bottom plate to occupy a large space. After the reagent rack is placed in the test kit, there is no place to put the bottom plate. After the bottom plate is connected to the test kit, the reagent rack is unstable and easy to tip over. The three need to be used together, but it is not convenient to combine and carry.

[0004] Therefore, it is necessary to provide a nucleic acid extraction kit to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a nucleic acid extraction kit to solve the problems raised in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

Several of the top blocks are detachably connected to the top surface of the bottom box, and the installation positions of the several top blocks respectively correspond to the positions of the several receiving slots.

[0008] The technical solution of the present invention is further configured as follows: a groove is provided at the bottom end of the top block, a convex portion is provided at the top end of the top block, and the convex portion is located in the groove of the adjacent top block.

[0009] The technical solution of the present invention is further configured as follows: a plurality of positioning blocks for connecting with the grooves are fixedly connected to the top surface of the bottom box, and a distance exists between the top end of the positioning block and the bottom end of the reagent rack.

[0010] The technical solution of the present invention is further configured as follows: guide frames for accommodating the top block and the positioning block are provided on both sides of the bottom end of the reagent box.

[0011] The technical solution of the present invention is further configured as follows: a sliding door is provided on the side wall of the bottom box for sliding to open the interior thereof.

[0012] The technical solution of the present invention is further configured as follows: a plurality of limit bars are fixedly connected to the top end of the side wall of the reagent rack, the bottom surfaces of the limit bars are against the top surface of the reagent reagent box, and a plurality of obstruction bars are fixedly connected to the bottom end of the side wall of the reagent rack, the obstruction bars are located below the limit bars and there is a gap between the two.

[0013] The technical solution of the present invention is further configured as follows: a convex ball for contacting the top block is provided on one side of the bottom end of the reagent rack, and a distance exists between the convex ball and the positioning block.

[0021] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention. Example

[0022] refer to Figures 1 to 4 As shown, the utility model provides a nucleic acid extraction kit, including a box cover, a reagent kit 1, a bottom box 4 and several reagent racks 2. The reagent kit 1 is provided with several array-distributed receiving slots 3, the reagent racks 2 are located in the receiving slots 3, the bottom box 4 is located below the reagent kit 1, and the bottom box 4 contains top blocks 5 whose number corresponds to the number of receiving slots 3. The several top blocks 5 are detachably connected to the top surface of the bottom box 4, and the installation positions of the several top blocks 5 correspond to the positions of the several receiving slots 3 respectively.

[0023] refer to Figures 1 to 4 As shown, a groove 6 is provided at the bottom end of the top block 5, and a convex portion 7 is provided at the top of the top block 5. The convex portion 7 is located in the groove 6 of the adjacent top block 5, so that the ends of the two adjacent top blocks 5 facing each other are in a nested state, so as to save space and ensure that all the top blocks 5 can be accommodated in the bottom box 4. A plurality of positioning blocks 8 for connecting with the groove 6 are fixedly connected to the top surface of the bottom box 4. There is a gap between the top of the positioning block 8 and the bottom end of the reagent rack 2. In this way, the positioning block 8 can facilitate the installation of the top block 5 through the groove 6. When the top block 5 is accommodated, When the reagent box 1 is put into the bottom box 4, the positioning block 8 will not contact the reagent rack 2, thereby avoiding affecting the reagent rack 2. Guide frames 9 for accommodating the top block 5 and the positioning block 8 are provided on both sides of the bottom end of the reagent box 1. The guide frames 9 are used to ensure that no matter when the top block 5 is stored or when the top block 5 is installed on the positioning block 8, when the bottom box 4 is connected to the reagent box 1, the guide frames 9 can play a restrictive role on the bottom box 4, allowing the bottom box 4 to overlap with the reagent box 1. A sliding door 10 is provided on the side wall of the bottom box 4 to slide open its interior, which is used to prevent the top block 5 from falling out of the bottom box 4.

[0024] refer to Figures 1 to 4As shown, the top of the side wall of the reagent rack 2 is fixedly connected to a plurality of limit bars 11, and the bottom surfaces of the limit bars 11 are against the top surface of the reagent reagent 1. The bottom end of the side wall of the reagent rack 2 is fixedly connected to a plurality of obstruction bars 12. The obstruction bars 12 are located below the limit bars 11 and there is a gap between the two. Through the limit bars 11, after the reagent rack 2 enters the receiving groove 3, the limit bars 11 can support it to ensure that the top ends of all reagent racks 2 are located in the same plane, which is convenient for sealing and cutting films. The obstruction bars 12 are used to prevent the reagent rack 2 from directly detaching from the receiving groove 3 when it is lifted by the top block 5, thereby improving the protection effect of the reagent rack 2. One side of the bottom end of the reagent rack 2 is provided with a convex ball 13 for contacting the top block 5. There is a gap between the convex ball 13 and the positioning block 8. The presence of the convex ball 13 ensures that when the top block 5 is installed on the positioning block 8 to lift the reagent rack 2, it will contact the convex ball 13 before the convex ball 13, thereby lifting one end of the reagent rack 2, making the reagent rack 2 tilted for easy removal.

[0025] refer to Figures 1 to 4 As shown, when the reagent rack 2 needs to be taken from the reagent kit 1, the bottom box 4 can be separated from the reagent kit 1 first, and then the sliding door 10 can be slid open to take out several top blocks 5 nested in each other from the bottom box 4 and install them on each positioning block 8 respectively. Then, the guide frame 9 at the bottom end of the reagent kit 1 can be aligned with the top blocks 5 on both sides to push out the reagent rack 2 above, so that the reagent rack 2 is in an inclined state, which is convenient for taking. If the reagent kit 1 needs to be carried to the sampling site or laboratory, the top block 5 can be removed from the positioning block 8 and placed in the bottom box 4, so that the bottom box 4 can overlap with the bottom end of the reagent kit 1 and will not affect the reagent rack 2, thereby facilitating its carrying.
