[0048] The following is combined Figures 1-4 The following describes embodiments of the present invention.
[0049] According to an embodiment of the present invention, in one aspect, a sample tube drawer assembly is provided, such as... Figure 1 , Figure 2 As shown, the sample tube drawer assembly includes a drawer body 100, which is adapted to be slidably mounted on the frame of the screening device. When the drawer body 100 is pulled out relative to the frame of the screening device, it facilitates the emptying of sample tubes and enables manual operation; when the drawer body 100 is pushed back relative to the frame of the screening device, the drawer body 100 is retracted into the frame of the screening device.
[0050] The drawer body 100 includes: side panels 110 and bottom panel 120.
[0051] The side panel 110 is adapted to be slidably connected to the frame; the bottom plate 120 and the side panel 110 together form a placement cavity, the bottom plate 120 is constructed as a deformable structure, and one side is connected to the side panel 110, and the other side is adapted to be connected to the frame; when the drawer body 100 is pulled out, the bottom plate 120 is adapted to open so that the placement cavity is connected to the sample tube sliding channel of the screening device; when the drawer body 100 is pushed back, the bottom plate 120 is adapted to close to avoid the internal structure of the screening device.
[0052] In the above embodiment, the bottom plate 120 in the side 110 of the drawer body 100 is designed as a deformable structure. When the drawer body 100 is pulled out, the bottom plate 120 opens to connect the placement cavity with the sample tube sliding channel of the screening device, so that the sample tube placed in the placement cavity can be tilted into the screening device through the bottom plate 120 of the drawer body 100, which is convenient for manual operation. When the drawer body 100 is pushed back, the bottom plate 120 can be gathered to avoid the internal structure of the screening device, thereby saving the internal space of the screening device and avoiding affecting the internal layout of the screening device.
[0053] Specifically, such as Figure 1 , Figure 2As shown, the base plate 120 is connected to the side panel 110 on one side and to the frame on the other side, and is constructed as a deformable structure. When it is necessary to pour sample tubes into the screening device, the operator pulls the side panel 110 to pull out the drawer body 100, that is, pulls the drawer body 100 out relative to the frame of the screening device. The base plate 120 will gradually open in the direction away from the frame until the placement cavity of the drawer body 100 is connected to the sample tube sliding channel of the screening device. After pouring sample tubes into the screening device, the operator pushes the side panel 110 to push the drawer body 100 back, that is, pushes the drawer body 100 back relative to the frame of the screening device. The base plate 120 will gradually converge in the direction closer to the frame, thereby avoiding the internal structure of the screening device, until the side panel 110 of the drawer body 100 is completely reset.
[0054] Furthermore, this embodiment does not limit the specific structural form of the base plate 120, which is constructed as a deformable structure. In one embodiment, the base plate 120 is constructed as a flexible structure, such as a rubber structure; in another embodiment, the base plate 120 is constructed as multiple rigid structures that are movably connected, such as multiple plates that are movably connected.

[0056] In the above embodiment, the base plate 120 is constructed as a plurality of folding plates 121 that are rotatably connected in sequence, so that it can be deformed according to the pushing and pulling movement of the drawer body 100 relative to the frame, resulting in a simple structure and stable connection.
[0057] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, when it is necessary to pour sample tubes into the screening device, the operator pulls out the drawer body 100 by pulling the side panel 110.

After pouring sample tubes into the screening device, the operator pushes the drawer body 100 back by pushing the side panel 110. Multiple folding plates 121 connected in sequence fold in sequence, thereby fully folding the bottom plate 120 to avoid the internal structure of the screening device.
[0058] Furthermore, two adjacent folding plates 121 arranged in sequence are rotatably connected by hinges 122.
[0059] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment does not limit the number of folding plates 121 that are sequentially rotated and connected. The number of folding plates 121 can be two, three, four, or even more.
[0060] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment, the number of folding plates 121 is two.
[0061] In the above embodiment, two rotatably connected folding plates 121 are provided to form the base plate 120, which simplifies the structure of the base plate 120.
[0062] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, when it is necessary to pour sample tubes into the screening device, the operator pulls the drawer body 100 out by pulling the side panel 110, and the two folding plates 121 rotate downward in sequence so that the bottom plate 120 gradually opens in the direction away from the frame; after pouring sample tubes into the screening device, the operator pushes the drawer body 100 back by pushing the side panel 110, and the two folding plates 121 rotate upward in sequence so that the bottom plate 120 gradually closes in the direction closer to the frame.
[0063] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the side panel 110 includes two first plates 111 disposed opposite to each other and a second plate 112 connected between the two first plates 111. The first plates 111 are adapted to be slidably connected to the frame, and the second plate 112 is adapted to be driven to push and pull the drawer body 100.
[0064] In the above embodiment, the side panel 110 is constructed by two first plates 111 arranged opposite to each other and a second plate 112 connected between the two first plates 111.

[0068] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the folding plate 121 near the second plate 112 is rotatably connected to the first plate 111. When multiple folding plates 121 connected in sequence are unfolded or folded in sequence, the folding plate 121 near the second plate 112 also rotates relative to the first plate 111 to avoid motion interference with the first plate 111 and ensure smoothness. Similarly, the folding plate 121 away from the second plate 112 is rotatably connected to the frame. When multiple folding plates 121 connected in sequence are unfolded or folded in sequence, the folding plate 121 away from the second plate 112 also rotates relative to the frame to ensure smoothness.

The folding plate 121 is rotatably connected to the first plate 111 through the cooperation of the rotating shaft and the shaft hole; the folding plate 121 away from the second plate 112 is rotatably connected to the frame through a hinge 122.
[0070] In some embodiments, such as Figure 1 , Figure 3 As shown, the base plate 120 is tilted towards the sample tube sliding channel.
[0071] In the above embodiment, the base plate 120 is inclined toward the sample tube sliding channel so that the sample tube placed in the placement cavity can be smoothly tilted by gravity.
[0072] Specifically, such as Figure 1 , Figure 3 As shown, the base plate 120 is tilted upward relative to the horizontal plane.
