DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, a detection cup includes a lid 1, an insert plate 2 and a cup body 3. The cup body 3 is a thin-walled structure, including a cup body portion 3-1, a transition portion 3-2 and a cup mouth portion 3-3 connected in sequence from bottom to top. The cup mouth portion 3-3 is cylindrical and has an external thread. The outer surface of the cup body portion 3-1 is a rectangular parallelepiped or a regular quadrangular pyramid with a larger upper portion and a smaller lower portion. The internal thread on the lid 1 is connected to the external thread of the cup mouth portion 3-3 of the cup body 3 by a thread.

[0027] The diameter of the cup mouth part 3-3 is larger than the diagonal length of the top of the cup body part 3-1; so that the projection of the cup body part 3-1 on the horizontal plane is completely inside the projection of the cup mouth part 3-3 on the horizontal plane; the top edge of the transition part 3-2 is a circle that matches the bottom of the cup mouth part 3-3; the bottom edge of the transition part 3-2 is a square that matches the bottom of the cup mouth part 3-3; the transition part 3-2 uses a slope that gradually expands from bottom to top to achieve a transition connection between the cup body part 3-1 and the cup mouth part 3-3; this connection form that avoids right angles helps to improve the strength of the cup body 3 (especially the transition part 3-2), and at the same time, reduces the adsorption force between the cup body and the production mold, making the production of the cup body 3 more stable.

[0028] like Figure 3 and Figure 4As shown, the cup body part 3-1 has four planar cup walls. Three of the cup walls are three detection surfaces; the fourth cup wall is an identification surface. The plug plate 2 is made of transparent material, including three unit plugs that are integrally formed and arranged in sequence; the unit plugs are planar; two adjacent unit plugs are connected by a folded edge that allows flipping. The three unit plugs are respectively fixed on the inner side walls corresponding to the three detection surfaces of the cup body part 3-1. The inner side surfaces of the three unit plugs are provided with reagent strip mounting slots 8 that are arranged in sequence along the horizontal direction. A detection reagent strip is installed in each reagent strip mounting slot 8.

[0029] Internal ribs 7 are vertically arranged on both sides of the inner side wall corresponding to the identification surface of the cup body part 3-1. The two internal ribs 7 are respectively close to the two opposite detection surfaces of the cup body part 3-1, and form two U-shaped card slot structures respectively. The three unit plugs are respectively a middle plug 2-1 and two end plugs 2-2. The two end plugs 2-2 are respectively connected to the two sides of the middle plug 2-1. The edges of the two end plugs 2-2 away from the middle plug 2-1 are respectively inserted into the two U-shaped card slot structures for constraint.

[0030] like Figure 3 and Figure 4 As shown, the inner side surfaces of the two end inserts 2-2 are provided with protrusions 6. The protrusions 6 are located at the top of the side of the end insert 2-2 away from the middle insert 2-1. The protrusions 6 on the two end inserts 2-2 correspond to the two inner ribs 7 respectively. The protrusions 6 press against the corresponding inner ribs 7, so that the edge of the side of the end insert 2-2 away from the middle side plate is tightly constrained in the corresponding U-shaped card groove structure, ensuring that the outer side of the insert can fit tightly on the inner wall of the cup body part 3-1, preventing the insert from falling off during transportation;

[0031] like Figure 5 As shown, the bottom of the edge of the two end plugs 2-2 away from the middle side plate is provided with a bevel 9, so that the two end plugs 2-2 can be smoothly inserted into the corresponding U-shaped slot structure, thereby completing the rapid assembly of the plug 2 and the cup body 3.

[0032] A concave label slot 4 is provided at the bottom of the outer wall corresponding to the identification surface of the cup body part 3-1; a temperature label is fixed in the label slot 4. The temperature label is used to detect and display the temperature of the sample. A sample volume scale is also printed on the outer wall corresponding to the identification surface of the cup body part 3-1. A triangular indicator 5 is provided on the top of the outer wall corresponding to any detection surface of the cup body part 3-1. The triangular indicator 5 is in the shape of an equilateral triangle, and one of the corners is set downward. The triangular indicator is used to facilitate the pasting and alignment of the cup wall label. In some preferred schemes, the triangular indicator 5 is set on the detection surface in the middle of the three detection surfaces.

[0033] In some embodiments, words such as "open", "close" or arrow patterns for identifying the direction of opening and closing the cover may be added to the surface of the cover 1.

[0034] In some embodiments, the bottom of the cup mouth part 3-3 and the edge of the lid 1 are provided with mutually matching deformable contact pieces. As the lid 1 is tightened, the deformable contact piece on the lid 1 gradually approaches the deformable contact piece on the cup mouth part 3-3 along the spiral line; until the deformable contact piece on the lid 1 passes over the deformable contact piece on the cup mouth part 3-3, an obvious click sound is emitted between the two deformable contact pieces; at this time, the inner cavity of the detection cup meets the set sealing requirements; the click sound is used to indicate to the user that the lid has been tightened.

[0035] The working principle of the utility model is as follows:

[0036] Unscrew the cover 1, add the liquid sample into the cup 3; the liquid sample contacts the sample adding area at the bottom of each detection reagent strip. Then, reinstall the cover 1 to the top opening of the cup 3, and each detection reagent strip detects one or more targets in the liquid sample.
