Please refer to FIG. 5 to FIG. 8, a cuvette holder 10 provided by an embodiment of the present invention includes: a holder body 100, a cuvette groove 200 is provided on the rack surface 110 of the holder body 100, and the cuvette groove 200 is used for The cuvette 300 is accommodated.

The two ends of the notch 210 of the cuvette groove 200 are respectively provided with supporting platforms, which are respectively the first supporting platform 120 and the second supporting platform 130. The cuvette 300 is respectively provided with a first supporting platform 120 and a second supporting platform 130. The flange 310 and the second flange 320, when the cuvette groove 200 accommodates the cuvette 300, the first support platform 120 supports the first flange 310, and the second support platform 130 supports the second flange 320, so that the reaction The cup 300 rides between the first support platform 120 and the second support platform 130 .

Wherein, the first supporting platform 120 is provided with a sliding surface 121 , and when the cuvette groove 200 accommodates the cuvette 300 , the sliding surface 121 abuts against the first flange 310 so that the cuvette 300 has a tendency to slide down. This is because when the cuvette 300 is placed in the cuvette groove 200, the first flange 310 rides on the lower surface 121, and the cuvette 300 will have a downward sliding tendency due to its own gravity, and will be in a stable state (reaction When the weight of the cup 300 and the received upward frictional force are balanced), the first flange 310 and the lower surface 121 are both slightly deformed.

Referring to FIG. 4 , the cuvette 300 is roughly in the shape of a hollow cuboid with one end open, including a bottom 301 , two opposite end cup walls 302 and two opposite side cup walls 303 , and the cup mouth is roughly rectangular. Referring to FIG. 5 , the corresponding cuvette slot 200 is a cuvette slot 200 with a rectangular cross section and a certain depth, including two opposite end inner walls 201 and two opposite side inner walls 202 . The two ends of the notch 210 of the cuvette groove 200 are respectively provided with a first support platform 120 and a second support platform 130, and the cuvette 300 is provided with a first flange 310 and a cup wall near the cup mouth. The second flange 320 corresponds to the first supporting platform 120 and the second supporting platform 130 respectively. As shown in Figure 4, the two ends of the rectangular cup opening of the cuvette 300 are respectively provided with the first flange 310 and the second flange 320, one end face cup wall 302 corresponds to the first flange 310, and the other end face The cup wall 302 corresponds to the second flange 320 . In some other embodiments, the cuvette 300 may also be provided with an annular flange extending in the circumferential direction at the cup mouth or the cup wall near the cup mouth, that is, the two opposite side walls 303 of the cuvette 300 There is also a flange on it. When the cuvette 300 is accommodated in the cuvette slot 200 , the portions of the ring flange corresponding to the first supporting platform 120 and the second supporting platform 130 are respectively the first flange 310 and the second flange 320 .

The sliding surface 121 can be a flat surface, a concave arc surface or a convex arc surface, etc., as long as it makes the cuvette 300 have a tendency to slide down when abutting against the first flange 310 . In one embodiment, the lower surface 121 is a plane, and the inclination angle of the lower surface 121 relative to the horizontal plane is 10° to 60°. By designing the lower surface 121 as a plane and designing the angle between the plane and the horizontal plane to be 10° to 60°, it is easier to keep the cuvette 300 in a stable state.

The first supporting platform 120 is provided with a sliding surface 121 , and when the cuvette 300 is accommodated in the cuvette slot 200 , the sliding surface 121 abuts against the first flange 310 so that the cuvette 300 has a tendency to slide down. It can be understood that the cuvette 300 shakes because the cuvette 300 moves upward in the vertical direction. When the cuvette 300 is accommodated in the cuvette holder 10 , relative to the horizontal plane, the downwardly inclined lower surface 121 can prevent the cuvette 300 from shaking. This is because when the cuvette 300 shakes and moves upward in the vertical direction, the frictional contact between the first flange 310 and the lower surface 121 causes the cuvette 300 to be subjected to a downward contact friction force, and the cuvette 300 is under its own gravity. It is not easy to shake under the combined resistance of the contact friction force. However, if the first flange 310 rests on a horizontal surface, the cuvette 300 will not receive a downward contact friction force. The cuvette holder 10 can prevent the cuvette 300 from shaking in the cuvette slot 200 without adding additional parts such as shrapnel, avoiding uncertain factors caused by adding shrapnel and other parts, and has high reliability.

The lower surface 121 can be arranged in various ways. As an implementable manner, as shown in Fig. 5 and Fig. 6, the lower surface 121 is inclined along the width direction of the notch 210; The sides of the cuvette 300 abut to prevent the cuvette 300 from sliding down. It can be understood that when the reaction cup 300 is only provided with the first flange 310 and the second flange 320 at the two ends of the cup mouth, the side of the reaction cup 300 refers to the side wall 303 of the reaction cup 300, that is, the reaction cup One of the side cup walls on the 300. When the cuvette 300 is provided with an annular flange around its opening, the side of the cuvette 300 refers to the side flange of the cuvette 300 , that is, the flange corresponding to one of the side walls 303 of the cuvette 300 . The lower surface 121 is obliquely arranged on the first support platform 120 along the width direction of the notch 210. When the cuvette 300 rests on the first support platform 120 through the first flange 310, the first flange 310 abuts against the lower surface 121 , so that the cuvette 300 has a downward tendency, and the cuvette 300 slides down slightly until the side of the cuvette 300 abuts against the side inner wall 202 of the cuvette groove 200 . Thus, the first support platform 120 supports the first flange 310, the second support platform 130 supports the second flange 320, and the inner wall of the cuvette groove 200 abuts against the side of the cuvette 300, so that the cuvette 300 rests on the second In the cuvette slot 200 between the first support platform 120 and the second support platform 130 , the cuvette 300 can finally be stably accommodated in the cuvette slot 200 .

5 to 8, in one embodiment, the first support platform 120 is also provided with a avoidance part 122, the avoidance part 122 and the lower surface 121 are arranged opposite to the width direction of the notch 210, and the distance between the avoidance part 122 and the lower surface 121 Create an avoidance space. When the cuvette groove 200 accommodates the cuvette 300, the lower surface 121 abuts against the first side 311 of the first flange 310, and the avoidance space makes the second side 312 of the first flange 310 suspended (see FIG. 6 ), and the first side 311 is opposite to the second side 312 . The avoidance space is formed by setting the escape portion 122. When the cuvette 300 slides down slightly to the position where the side wall 303 of the cuvette 300 abuts against the side inner wall 202 of the cuvette groove 200, the second side 312 of the first flange 310 is suspended. The contact with the bracket body 100 is beneficial to ensure good contact between the side wall 303 of the cuvette 300 and the side inner wall 202 of the cuvette groove 200 . Since the side walls 303 of the cuvette 300 and the inner wall 202 of the cuvette groove 200 have a large contact area and many contact points, the cuvette 300 can be stably accommodated in the cuvette groove 200 without shaking. The escape portion 122 may be a right-angled groove disposed opposite to the lower surface 121 , and an escape space is formed between the right-angle groove and the lower surface 121 .

It can be understood that, as introduced in the background art, the gap between the wall of the cuvette 300 and the cuvette groove 200 is very small, so the sliding distance of the cuvette 300 must be very short. The reaction cup 300 slides down slightly for a certain distance as a whole, and the second flange 320 at the other end of the reaction cup 300 can have various states. The second flange 320 of the cuvette 300 can be moved down a certain distance with the cuvette 300, and the side of the cuvette 300 abuts against the inner wall of the cuvette groove 200, and the second flange 320 and the second supporting platform 130 are also in a position. contact state, and jointly with the first flange 310 to support the cuvette 300 on the cuvette slot 200 . If the cuvette 300 is directly placed at the position where the side wall 303 of the cuvette 300 is just in contact with the inner wall of the cuvette groove 200, then the cuvette 300 may hardly slide down, and the cuvette 300 may hardly slide down, and the cuvette 300 may not slide down when it is in contact with the holder body 100. The part is directly deformed slightly.

Please continue to refer to FIG. 5 and FIG. 6 , in some embodiments, the second supporting platform 130 may have a second lower surface 131 , and the second lower surface 131 abuts against the second flange 320 . The second lower surface 131 can be inclined along the width direction of the notch 210 , and the second lower surface 131 can also be inclined along the length direction of the notch 210 . Referring to FIG. 5 and FIG. 6 , the second sliding surface 131 is inclined along the width direction of the notch 210 , which is consistent with the direction of the slope of the sliding surface 121 . In some other embodiments, the inclination direction of the second lower surface 131 is opposite to that of the lower surface 121 .

In the embodiment shown in FIGS. 5 to 8 , the sliding surface 121 is inclined along the width direction of the slot 210 , the second sliding surface 131 is also inclined along the width direction of the slot 210 , and the direction of the slope of the second sliding surface 131 is consistent with that of the sliding surface 121 . When the cuvette 300 rests on the lower surface 121 and the second lower surface 131 , the cuvette 300 slides down slightly until the side wall 303 of the cuvette 300 abuts against the side inner wall 202 of the cuvette groove 200 . Thus, the first support platform 120 supports the first flange 310, the second support platform 130 supports the second flange 320, and the side inner wall 202 of the cuvette groove 200 abuts against the side wall 303 of the cuvette 300, so that the reaction The cuvette 300 is placed in the cuvette slot 200 between the first support platform 120 and the second support platform 130 , so that the cuvette 300 can be stably accommodated in the cuvette slot 200 finally.

As another practicable manner, the lower surface 121 is inclined along the length direction of the notch 210; when the cuvette 300 slot 200 accommodates the cuvette 300, the second support platform 130 holds the second flange 320 to block the cuvette 300. slide. The lower surface 121 is obliquely arranged on the first support platform 120 along the length direction of the notch 210 , when the cuvette 300 rests on the first support platform 120 through the first flange 310 , the first flange 310 abuts against the lower surface 121 , the cuvette 300 has a downward tendency due to its own gravity, and the cuvette 300 as a whole slides slightly until the second flange 320 rests on the second support platform 130, so that the cuvette 300 can finally be stably accommodated in the cuvette slot Within 200. When the cuvette 300 slides down, the second flange 320 may directly move down and abut against the second supporting platform 130 . In some embodiments, the second supporting platform 130 can have a second lower surface 131 , and the second lower surface 131 abuts against the second flange 320 .

In some embodiments, the second sliding surface 131 may be inclined along the width direction of the notch 210 . In some other embodiments, the second sliding surface 131 may also be inclined along the length direction of the notch 210 .

Referring to FIG. 9 , it is a schematic cross-sectional view along the length direction of the notch 210 when the cuvette 300 is in the cuvette slot 200 according to an embodiment. The lower sliding surface 121 is inclined along the length direction of the notch 210, and the second sliding surface 131 is inclined along the length direction of the notch 210 as an example. 121 and the second lower surface 131 , relative to the horizontal plane, the downwardly inclined lower surface 121 and the second lower surface 131 can make the cuvette 300 less likely to shake. This is due to the frictional contact between the first flange 310 and the lower surface 121, and the frictional contact between the second flange 320 and the second lower surface 131 so that the reaction cup 300 is subjected to a downward contact friction force, and the reaction cup 300 It is not easy to shake under the combined resistance of its own gravity and the contact friction.

Of course, in some embodiments, as shown in FIG. 10 , which is a simple schematic cross-sectional view along the length direction of the notch 210 when the cuvette 300 of another embodiment is in the cuvette groove 200, the second supporting platform 130 does not need a second The lower surface 131 has steps instead. When the cuvette 300 rides on the first support platform 120 through the first flange 310 , the first flange 310 abuts against the lower surface 121 . When the cuvette 300 rides on the second supporting platform 130 through the second flange 320 , the second flange 320 rides on the step.

As an implementable manner, the second support platform 130 has the same structure as the first support platform 120 , and the first support platform 120 and the second support platform 130 form plane symmetry with each other. Referring to FIGS. 5-8 , it can be understood that when the first support platform 120 has a lower surface 121 inclined along the width direction of the notch 210 , the second support platform 130 also has a second lower surface 131 inclined along the width direction of the notch 210 , and the orientations of the lower surface 121 and the second lower surface 131 are consistent. The first support platform 120 is provided with an escape portion 122 , and the second support platform 130 is also provided with an escape portion 122 . In other embodiments, when the first supporting platform 120 is provided with a supporting surface 123 (which will be mentioned in later embodiments), the second supporting platform 130 is also provided with a supporting surface 123 . When the first support platform 120 has the lower surface 121 inclined along the length direction of the notch 210, the second support platform 130 also has the second lower surface 131 inclined along the length direction of the notch 210, and the lower surface 121 and the second lower surface 131 are all inclined to the notch 210.

By designing the second support platform 130 to have the same structure as the first support platform 120, and making the first support platform 120 and the second support platform 130 form plane symmetry with each other, not only is it beneficial for the cuvette 300 to be stably accommodated in the cuvette slot 200, and when the cuvette groove 200 is processed on the bracket body 100, it is more convenient for one-time processing and molding of the cuvette groove 200.

Referring to Fig. 11 and Fig. 12, Fig. 11 is a simple schematic diagram of a reaction cup 300 in the cuvette groove 200 of an embodiment, and Fig. 12 is a simple schematic diagram of another embodiment of the cuvette 300 in the cuvette groove 200, surrounded by dotted lines A portion indicates the cuvette body portion of the cuvette 300 that is covered by the holder body 100 . As another practicable manner, the first support platform 120 can also be provided with a support surface 123, the support surface 123 and the lower surface 121 are oppositely arranged in the width direction of the notch 210, and the lower surface 121 is inclined along the width direction of the notch 210 . When the cuvette groove 200 accommodates the cuvette 300, the lower surface 121 abuts against the first edge 311 of the first flange 310, and the support surface 123 abuts against the second edge 312 of the first flange 310 to prevent the cuvette 300 from sliding down. One side 311 is opposite to the second side 312 . By setting the support surface 123 on the opposite side of the lower surface 121, when the cuvette groove 200 accommodates the cuvette 300, the first flange 310 can ride on the substantially V-shaped groove formed by the lower surface 121 and the support surface 123 (as shown in FIG. 11. When the support surface 123 is a plane inclined relative to the horizontal plane), the two side edges of the first flange 310 respectively contact with the lower surface 121 and the support surface 123 and form friction. Therefore, the cuvette 300 can be stably accommodated in the cuvette groove 200 . In other embodiments, as shown in FIG. 12 , the supporting surface 123 may also be provided with a step to support the second side 312 of the first flange 310 .
