Description

Technical Field

[0001] The utility model relates to a kit, in particular to a kit for nucleic acid detection of respiratory pathogens. Background Technique

[0002] Detection kits are generally used in hospitals and pharmaceutical enterprises. During the use of detecting respiratory diseases in the human body, it is necessary to use a kit to store reagents.

[0003] In the prior art, for a kit for detecting respiratory diseases, the reagents are only vertically placed inside the placement rack. Even after closing the box lid, the reagent tubes inside the box are still in an unfixed state. The kit is prone to external factors, causing the reagent tubes to shake, resulting in poor stability of the reagent tubes. Content of the Utility Model

[0004] The purpose of the embodiment of the utility model is to provide a kit for nucleic acid detection of respiratory pathogens, aiming to solve the technical problems proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A kit for nucleic acid detection of respiratory pathogens includes a box body. A base is arranged inside the box body, and an installation groove for placing reagent tubes is opened on the base;

[0007] The base is provided with an adjustment cavity. A support shaft is rotatably supported inside the adjustment cavity, and a plurality of eccentric cams are installed on the support shaft;

[0008] A support rod is fixedly supported inside the adjustment cavity. An arc-shaped clamping plate is supported on the support rod through an elastic member, and the arc-shaped clamping plate is used for tightly fixing the waist of the reagent tube.

[0009] Further, the arc-shaped concave surface of the arc-shaped clamping plate has a rubber layer, which can avoid damaging the reagent tube when the arc-shaped clamping plate is used to tightly fix the reagent tube.

[0010] Further, the elastic member includes a spring. The spring is sleeved on the support rod. One end of the spring is connected to the inner side wall of the adjustment cavity, and the other end of the spring is connected to a support plate. The support plate is integrally formed on one side of the arc-shaped clamping plate.

[0011] Further, through holes are opened on the support plate, and the support rod passes through the through holes.

[0012] Further, one side of the box body is provided with a box lid through a hinge for opening and closing.

[0013] Further, a pressure rod is slidably arranged up and down on the base. A straight tooth surface is arranged on the pressure rod, and a gear meshing with the straight tooth surface is coaxially and fixedly installed on the support shaft.

[0014] Further, a guide post is provided at the top end of the pressure rod. The guide post is slidably arranged on the pressing plate, and one end of the pressing plate is hinged to the top of the base.

[0015] Compared with the prior art, the beneficial effects of the nucleic acid detection kit for respiratory tract pathogenic bacteria of the present utility model are as follows:

[0016] First, when the box cover is closed on the box body, the box cover moves the pressing plate downward, and then pushes the pressure rod downward to realize the downward movement of the pressure rod in the vertical direction. Under the meshing and linkage action of the gear and the straight tooth surface, the support shaft rotates, and then drives the eccentric cam to push the arc-shaped clamping plate to move, so as to tightly fix the reagent tube, ensuring the stability of the reagent tube in the box body;

[0017] Second, when the box cover is opened, under the reset and support action of the elastic member, the pressing plate resets and moves upward. At this time, after the box cover is opened, the reagent tube can be conveniently taken out from the corresponding installation groove, and the operation is convenient. Description of the Drawings

[0032] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] The following details the specific implementation of the present utility model in conjunction with specific embodiments.

[0034] As Figures 1-3 shown, in an embodiment of the present utility model, a nucleic acid detection kit for respiratory tract pathogenic bacteria, the detection kit includes a box body 100, a base 300 is arranged in the box body 100, and an installation groove 301 for placing a reagent tube 400 is opened on the base 300; one side of the box body 100 is provided with a box lid 200 in a hinge-opening and closing manner.

[0035] Further, as Figure 2 , Figure 4 and Figure 5 shown, the base 300 is provided with an adjustment cavity 302, a support shaft 307 is rotatably supported in the adjustment cavity 302, and a plurality of eccentric cams 309 are installed on the support shaft 307; a support rod 501 is also fixedly supported in the adjustment cavity 302, and an arc-shaped clamping plate 500 is supported on the support rod 501 through an elastic member, and the arc-shaped clamping plate 500 is used to tightly fix the waist of the reagent tube 400.

[0036] Wherein, the arc-shaped concave surface of the arc-shaped clamping plate 500 has a rubber layer 505, which avoids damaging the reagent tube 400 when the arc-shaped clamping plate 500 is used to tightly fix the reagent tube 400.

[0037] Please continue to refer to Figures 4-7, in the embodiment of the present utility model, the elastic member includes a spring 503. The spring 503 is sleeved on the support rod 501. One end of the spring 503 is connected to the inner side wall of the adjustment cavity 302, and the other end of the spring 503 is connected to the support plate 504. The support plate 504 is integrally formed on one side of the arc-shaped clamping plate 500;

[0038] Preferably, a through hole 502 is formed on the support plate 504, and the support rod 501 passes through the through hole 502.

[0039] Optionally, the spring 503 provided by the present utility model can be in multiple segments. The multiple segments of the spring 503 are all sleeved on the support rod 501 and are used for elastically supporting the arc-shaped clamping plate 500. After the arc-shaped clamping plate 500 generates displacement under the pushing action of the eccentric cam 309, with the release of the eccentric cam 309 on the arc-shaped clamping plate 500, the arc-shaped clamping plate 500 can be reset. When the arc-shaped clamping plate 500 is reset, it no longer presses and fixes the reagent tube 400.

When the pressure rod 304 moves in the vertical direction, under the meshing and linkage action of the gear 308 and the straight tooth surface 306, the support shaft 307 rotates, and then drives the eccentric cam 309 to push the arc-shaped clamping plate 500 to move, so as to press and fix the reagent tube 400.

[0041] Furthermore, a guide post 305 is arranged at the top end of the pressure rod 304. The guide post 305 is slidably arranged on the pressing plate 303, and one end of the pressing plate 303 is hinged to the top of the base 300. When the box cover 200 is closed on the box body 100, the box cover 200 moves the pressing plate 303 downward, and then pushes the pressure rod 304 downward, so as to realize the downward movement of the pressure rod 304 in the vertical direction; wherein, when the box cover 200 is opened, under the reset support action of the elastic member, the pressing plate 303 is reset and lifted. At this time, after the box cover 200 is opened, it is convenient to take out the reagent tube 400 from the corresponding installation groove 301.

[0042] The above solutions are only descriptions of a preferred example, but are not limited thereto. When implementing the present utility model, appropriate replacements and / or modifications can be made according to the needs of users.
