[0029] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0031] The present application provides a sample container adapter which can be compatible with tubular containers and cup-shaped containers, so as to stably place the above-mentioned containers on a sample support, avoiding frequent replacement of corresponding adapters due to different detection objects, and making the detection steps more complicated. The tubular container can be a centrifugal tube, and the cup-shaped container can be a sample cup or a Hitachi cup.

[0032] As shown in the drawings, Figure 1 The sample container adapter includes a containing cavity 1 and a positioning body 2 connected with each other, and the containing cavity 1 and the positioning body 2 extend in the same direction. The containing cavity 1 can be provided as a cylindrical cylinder, that is, a circular opening is arranged on one side of the containing cavity 1, an end face of one end of the opening is provided as a limiting step 7, the opening extends on the other side along the height direction of the containing cavity 1, forming an inner cavity with a depth smaller than the height of the containing cavity 1, so that the other side of the containing cavity 1 has a closed bottom cover, a positioning groove 3 is arranged on the inner side of the bottom cover of the containing cavity 1, and an elastic member 4 extending inward is arranged on the inner wall of the containing cavity 1. After the sample container is placed into the containing cavity 1, the elastic member 4 applies a pushing force to the sample container, so that the fitting degree of the sample container to the inner wall of the containing cavity 1 is more closely, and the position of the sample container in the containing cavity 1 is kept stable. In addition, the bottom cover of the containing cavity 1 is connected with the positioning body 2, and the positioning body 2 can also be provided as a cylindrical pipe. The positioning body 2 can be inserted into the positioning hole 9 of the sample support, so as to fix the whole sample container adapter on the sample support.

[0033] As described above, the sample container types include cup-shaped containers and tubular containers. When a tubular sample container is used, Figure 2 and Figure 3As shown, the tapered bottom of the tubular container 100 is matched with the size of the positioning groove 3 of the accommodating cavity 1, when the tubular container 100 extends into the bottom of the accommodating cavity 1, the bottom of the tubular container 100 is placed in the positioning groove 3, the outer wall of the bottom of the tubular container 100 is attached to the groove of the positioning groove 3, the position of the bottom of the tubular container 100 is locked, the sidewall of the tubular container 100 is resisted by the elastic member 4, and is tightly attached to the inner cavity of the accommodating cavity 1, so that the tubular container 100 remains in the vertical state.

[0034] The opening end of the accommodating cavity 1 naturally has an annular end face, which is arranged as a limiting step 7, as shown in the drawings Figure 4 As shown, for the cup-shaped container 200 with a stepped structure, after being placed in the sample container adapter, the limiting step 7 bears the stepped structure of the cup-shaped container 200, thereby determining the position of the port of the cup-shaped container 200 in the height direction of the sample container adapter, and the distance from the port to the bottom of the cup-shaped container 200 is fixed, and the limiting step 7 determines the position of the cup-shaped container 200 in the accommodating cavity 1.

[0035] In addition, the accommodating cavity 1 and the positioning body 2 are both cylinders, the axes of the two cylinders coincide, and the outer diameter of the accommodating cavity 1 is larger than the outer diameter of the positioning body 2, the end face 8 of the accommodating cavity 1 facing the positioning body 2 is attached to the end face of the positioning hole 9 of the sample holder, and the end face 8 here is an annular step face, that is, an annular step face is formed at the connection between the accommodating cavity 1 and the positioning body 2, and the annular step face separates the sample container adapter into two parts, after the positioning body 2 is inserted into the positioning hole 9 of the sample holder, the annular step face is attached to the end face of the positioning hole 9 of the sample holder, so that the accommodating cavity 1 is always outside the sample holder, avoiding the part of the accommodating cavity 1 extending into the positioning hole 9, the position of the sample container deviating, and the detection device failing to complete the sampling work of the sample in the sample container.

[0036] In order to ensure the stable position of the sample container in the sample container adapter, the setting direction of the sample container is consistent with the setting direction of the accommodating cavity 1, the sample container is vertically arranged in the accommodating cavity 1, and the bottom of the sample container is limited by the positioning groove 3, thereby ensuring the position of the sample container in the sample container adapter in the height direction; in order to avoid the gap between the inner cavity sidewall of the accommodating cavity 1 and the outer wall of the sample container being too large, the elastic member 4 resists the outer wall of the sample container to prevent the sample container from being skewed in the inner cavity of the accommodating cavity 1; similarly, the setting direction of the sample container adapter as a whole will also affect the position of the sample container, therefore, the outer diameter of the positioning body 2 is attached to the inner wall of the positioning hole 9 of the sample holder, the end face 8 (i.e. the annular step face) of the positioning body 2 is attached to the end face of the positioning hole 9, and the combination of the sample container adapter and the sample container can stably remain in the vertical state on the sample holder, and the height of the sample container relative to the fixing hole is determined, so that the detection device can normally sample and detect the sample to be tested.

[0037] The positioning groove 3 is a structure for fixing the bottom of the sample container. Since the cross section of the bottom of the sample container is circular, the positioning groove 3 that is fitted with the bottom of the sample container should also be a circular groove. The axis of the positioning groove 3 should coincide with the axis of the containing cavity 1, so that the setting direction of the bottom of the sample container is along the axis direction of the containing cavity 1, that is, the sample container is vertically arranged in the containing cavity 1. The inner wall diameter of the positioning groove 3 gradually decreases along the depth direction of the positioning groove 3, and the maximum inner diameter of the positioning groove 3 is smaller than the inner diameter of the containing cavity 1, so that the inner wall of the positioning groove 3 can be as much as possible to be fitted with the bottom of the sample container, thereby ensuring the fixing effect of the positioning groove 3 on the position of the bottom of the sample container, and also avoiding that the maximum diameter of the inner wall of the positioning groove 3 is too large and the depth of the positioning groove 3 is limited, resulting in that the inclination angle of the gradually tapered inner wall of the positioning groove 3 is small, and the sample container can slide on the inner wall of the positioning groove 3, so that it is difficult to fix the state of the bottom of the sample container.

[0038] Further, the elastic member 4 is provided with an observation window 6 at the opposite side wall of the containing cavity 1. The observation window 6 is a rectangular groove penetrating through the side wall of the containing cavity 1. The setting direction of the observation window 6 is parallel to the axis of the containing cavity 1. The observation window 6 extends from the port of the containing cavity 1 to the bottom cover where the positioning groove 3 is arranged. The length of the observation window 6 is the same as the part of the sample container that extends into the containing cavity 1. The operator can observe the overall detection result in the sample container from the outside.

[0039] In addition, the containing cavity 1 is provided with a clamping member 5 on the outer wall. The clamping member 5 is composed of two elastic buckles. The setting direction of each elastic buckle is perpendicular to the containing cavity 1, and the two elastic buckles are symmetrically distributed on both sides of the observation window 6. The buckle includes an extension body and a clamping body. One end of the extension body is connected with the outer wall of the containing cavity 1, and the other end extends away from the end of the observation window 6. There is a certain distance between the end of the extension body and the observation window 6, so that the clamping member 5 has a space for placing the cover of the sample container. In addition, the end of the extension body is also provided with a clamping body. The clamping body and the extension body are arranged at a certain angle, and extend towards the end of the observation window 6. After the sample container is fixed in the containing cavity 1, the cover of the sample container is placed between the two elastic buckles. The cover is pressed, so that the cover is in contact with the inclined surface of the clamping body. With the pushing of the cover, each clamping body is pushed to the side. When the distance between the two clamping bodies is the same as the width of the cover, the cover is clamped into the inner side of the two clamping bodies. The two clamping bodies rebound to the original position, clamping the cover of the sample container between the two elastic buckles, and completing the fixation of the cover of the sample container, preventing the cover from being hindered when the detection equipment takes samples.

[0040] Please continue to refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 3 The elastic member 4 can be specifically arranged as an integral elastic protrusion uniformly distributed along the circumference of the containing cavity 1. The elastic protrusion extends towards the inside of the containing cavity 1. The outer side wall of the containing cavity 1 has a recessed groove 41. The recessed groove 41 and the elastic member 4 correspond one by one. The containing cavity 1 and the elastic member 4 are an integral forming structure.

[0041] In this way, the elastic protrusion and the overall structure of the mounting cavity 1 are reliable, and the use strength is improved.

[0042] In some embodiments, the positioning body 2 of the sample container adapter can also be provided with a chamfered bottom. When the sample container is installed, the positioning body 2 is inserted into the sample rack positioning hole 9. Since the outer diameter of the bottom provided with the chamfer is smaller, it is more convenient to insert the positioning hole 9.

[0043] The present application also provides a sample rack, as shown in the accompanying drawings Figure 5 The sample rack has a plurality of mounting holes, each mounting hole has a hole diameter matched with the positioning body 2 of the sample container adapter, and the depth of the mounting hole is consistent with the height of the positioning body 2. When the positioning body 2 is inserted into the positioning hole 9, the sample container adapter can be guaranteed to be vertically arranged in the sample rack.

[0044] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between the entities.

[0045] The principles and implementation modes of the present application are described by using specific examples in the present specification. The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in several ways. These improvements and modifications also fall within the protection scope of the present application.
