A support part is arranged at the bottom of the reagent tube body to provide support for the reagent tube body, so that the reagent tube can stand upright on the desktop without a reagent rack, which is convenient to use. And through the setting of the connecting protrusion and the connecting groove, it is convenient to connect multiple reagent tubes together for easy carrying.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A vertical reagent tube includes a reagent tube body and a cover body that are detachably connected. The bottom of the reagent tube body bulges downward to form a protrusion part. A support part is formed at the bottom of the reagent tube body. The shape of the support part is cylindrical and covers the periphery of the protrusion part. A plurality of scale lines are arranged on the side wall of the reagent tube body.

[0006] Further, a plurality of connecting protrusions and connecting grooves are formed on the cover body. The connecting protrusions and the connecting grooves are arranged at intervals. The connecting protrusions are used for plugging into the connecting grooves of another cover body so that multiple cover bodies can be connected together.

[0007] Further, three connecting protrusions and three connecting grooves are arranged on the same cover body. The connecting protrusions and the connecting grooves are evenly distributed circumferentially along the center line of the cover body.

[0008] Further, the cross-sectional shape of the connecting protrusion is set as a trapezoid, and the shape of the connecting groove is adapted to the shape of the connecting protrusion.

[0009] Further, the size of the connecting protrusion is smaller than the size of the connecting groove, so that there is an activity gap between the connecting protrusion and the connecting groove when the connecting protrusion is plugged into the connecting groove.

[0010] Furthermore, the protrusion thickness of the connecting protrusion is set to be a difference between 1 / 15 and 1 / 10 of the radius of the cover body.

[0011] Furthermore, the outer diameter of the reagent tube body is smaller than the outer diameter of the cover body and twice the depth of the connecting groove.

[0012] Furthermore, the shape of the protrusion is set to be conical or arc-shaped.

[0013] Furthermore, the cover body and the reagent tube body are threadedly connected, and a sealing ring is arranged in the cover body. When the cover body is connected to the reagent tube body, the open end of the reagent tube body can abut against the sealing ring.

[0025] As Figure 1 shown, a vertical reagent tube in this embodiment includes a reagent tube body 1 and a cover body 2 that are detachably connected. A convex portion 102 is formed by the bottom of the reagent tube body 1 bulging downward. A support portion 101 is formed at the bottom of the reagent tube body 1. The shape of the support portion 101 is cylindrical and wraps around the periphery of the convex portion 102. A plurality of scale lines 103 are provided on the side wall of the reagent tube body 1. The shape of the convex portion 102 is set to be conical or arc-shaped. In the present utility model, a support portion 101 is provided at the bottom of the reagent tube body 1 to provide support for the reagent tube body 1, so that the reagent tube can stand upright on the desktop away from the reagent rack, which is convenient to use. And the setting of the convex portion 102 avoids generating dead corners at the bottom of the reagent tube, reduces the residue of the reagent liquid at the bottom of the reagent tube, and is convenient for cleaning the reagent tube. At the same time, the setting of the scale lines 103 is convenient for directly reading the volume of the reagent liquid inside the reagent tube.

[0026] Please refer to Figure 2 , the cover body 2 and the reagent tube body 1 are threadedly connected (not shown in the figure). An installation groove is provided inside the cover body 2, and a sealing ring 3 is installed in the installation groove. When the cover body 2 is connected to the reagent tube body 1, the open end of the reagent tube body 1 can abut against the sealing ring 3.

[0027] Please refer to Figure 3 andFigure 1 , a plurality of connecting protrusions 201 and connecting grooves 202 are formed on the cover body 2. The connecting protrusions 201 and the connecting grooves 202 are arranged at intervals. The connecting protrusions 201 are used for inserting into the connecting grooves 202 of another cover body 2 so that a plurality of cover bodies 2 can be connected into one body. The utility model can facilitate the connection of a plurality of reagent tubes into one body through the arrangement of the connecting protrusions 201 and the connecting grooves 202, utilize the connection of a plurality of reagent tubes to provide support for each other, and it is not easy for the plurality of reagent tubes to fall after connection, which is convenient for improving the stability of the placement of a plurality of reagent tubes, avoiding the overturning of the reagent tubes caused by external vibration, and is also convenient for storage. In addition, the detachable connection method does not affect the normal use of the reagent tubes.

[0028] In this embodiment, three connecting protrusions 201 and three connecting grooves 202 are provided on the same cover body 2, so that one cover body 2 can be connected to 6 cover bodies 2 at the same time with one cover body 2 as the center. The connecting protrusions 201 and the connecting grooves 202 are evenly distributed circumferentially along the center line of the cover body 2, and the space between a plurality of reagent tubes is fully utilized to complete the connection.

[0029] The outer diameter of the reagent tube body 1 is smaller than the difference between the outer diameter of the cover body 2 and twice the depth of the connecting groove 202. Considering that when a plurality of reagent tubes are connected, it is necessary to prevent the reagent tube body 1 from blocking the connecting groove 202, so the above-mentioned dimensional requirements are generated. The protruding thickness of the connecting protrusion 201 is set between 1 / 15 and 1 / 10 of the radius of the cover body 2. The protruding thickness of the connecting protrusion 201 will affect the depth of the connecting groove 202, and the two change in the same proportion. If the protruding thickness of the connecting protrusion 201 is too large, the overall size of the cover body 2 will be too large and inconvenient to use. If the protruding thickness of the connecting protrusion 201 is too small, the connection effect will be affected.

[0030] The cross-section of the connecting protrusion 201 is defined as the first cross-section, and the shape of the first cross-section is set as a trapezoid. Specifically, the first cross-section includes a first upper base and a first lower base. The length of the first upper base is less than that of the first lower base. The first upper base is connected to the cover body 2, and one side of the first lower base faces the outside of the cover body 2. The shape of the connecting groove 202 is adapted to the shape of the connecting protrusion 201. That is to say, the connecting groove 202 is correspondingly set as a dovetail groove, and its cross-section is defined as the second cross-section, and the second cross-section is correspondingly trapezoidal. The second cross-section includes a second upper base and a second lower base. The size of the connecting protrusion 201 is smaller than the size of the connecting groove 202. Here, the size refers to that the size of the first upper base is less than the size of the second upper base, and the size of the first lower base is less than the size of the second lower base, and the sides are parallel to each other. When the connecting protrusion 201 is inserted into the connecting groove 202, there is an activity gap 4 between the connecting protrusion 201 and the connecting groove 202. The setting of the activity gap 4 is mainly considered to facilitate disassembly and avoid jamming. And when one of the cover bodies 2 is impacted, each cover body 2 can be buffered through the activity gap 4 to reduce the damage of the cover body 2.

[0031] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
