[0030] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] This embodiment provides a test strip clamping box, which is mainly used for clamping test strips of different widths.

[0032] AsFigure 2 , Figure 3 and Figure 7 As shown in Figure 2 , Figure 3 and Figure 7 , it includes an upper cover body 1 and a lower cover body 2 that is buckled with the upper cover body 1. The test strip 3 is installed between the inner cavities formed by the upper cover body 1 and the lower cover body 2. Among them, an observation groove 102 and a dropping port 104 that communicate with its inner cavity are provided on the upper cover body 1. Specifically, the test strip 3 is located directly below the observation groove 102 and the dropping port 104.

[0033] Through the above settings, a detection reagent is dropped into the inner cavity formed by the upper cover body 1 and the lower cover body 2 through the dropping port 104, so that the detection reagent contacts the end of the test strip 3, and then the reagent is sucked into the test strip 3. At this time, the state of the display area on the test strip 3 can be observed through the observation groove 102, so as to judge the test result.

[0034] The test strip 3 is a disposable item. After the test strip 3 is used up, in order to prevent the reagent on the test strip 3 from volatilizing outward through the observation groove 102. In this embodiment, as Figure 2 and Figure 3 shown, a transparent sealing window 103 is installed in the observation groove 102, and the observation groove 102 is encapsulated by the sealing window 103 to prevent the reagent on the test strip 3 from volatilizing to the outside. It should be noted here that the sealing window 103 can be made of transparent plastic material or glass material to facilitate observing the state of the test strip 3.

[0035] In order to be able to buckle the upper cover body 1 and the lower cover body 2, in this embodiment, as Figure 4 , Figure 6 and Figure 9 shown, a buckling groove 105 is provided on the inner side wall of the upper cover body 1, and a buckling protrusion 24 that is aligned with the buckling groove 105 is provided on the lower cover body 2. After the lower cover body 2 is pressed on the upper cover body 1, at this time, the buckling protrusion 24 is inserted into the buckling groove 105, and then the fixation of the upper cover body 1 and the lower cover body 2 is realized.

[0036] In order to fix the test strip 3, in this embodiment, as Figure 4 and Figure 5 shown, a limiting plate 106 is provided on the top wall of the upper cover body 1 on one side of the observation groove 102. Among them, the limiting plate 106 is arranged along the length direction of the clamping box. As Figure 8 shown, the limiting plate 106 extends vertically downward. A clamping part 4 and a telescopic assembly 5 for sliding the clamping part 4 along the width direction of the clamping box are provided on the other side of the observation groove 102 relative to the limiting plate 106. Specifically, one end of the telescopic assembly 5 is fixedly connected to the clamping part 4, and the other end is fixedly connected to the inner wall of the upper cover body 1. Among them, the test strip 3 is installed between the limiting plate 106 and the clamping part 4.

[0037] In order to realize the movement of the clamping part 4, in this embodiment, as Figure 7 and Figure 8 shown, the telescopic assembly 5 includes a telescopic tube 51, a telescopic rod 52 and a compression spring 53. Among them, the telescopic tube 51 is fixedly installed on the inner wall of the upper cover 1 and is arranged along the width direction of the clamping box. One end of the telescopic rod 52 is fixedly connected to the clamping part 4, and the other end extends into the inner cavity of the telescopic tube 51. The outer wall of the telescopic rod 52 is slidably connected to the inner wall of the telescopic tube 51. The compression spring 53 is sleeved outside the telescopic tube 51. One end of the compression spring 53 abuts against the inner wall of the upper cover 1, and the other end of the compression spring 53 abuts against the clamping part 4.

[0038] In order to be able to clamp the test strip 3 between the limiting plate 106 and the clamping part 4, in this embodiment, as Figure 7 shown, wherein, a limiting groove 1061 is provided on one side of the limiting plate 106 close to the clamping part 4. During the installation process, first place one side edge of the test strip 3 in the limiting groove 1061 and make the side edge of the test strip 3 abut against the side wall of the limiting plate 106. Then push the clamping part 4 away from the test strip 3 to further compress the compression spring 53 to make the test strip 3 in a horizontal state. Then, release the restriction on the clamping part 4, and the compression spring 53 pushes the clamping part 4 to reset, thereby clamping the test strip 3 between the limiting plate 106 and the clamping part 4 to realize the fixation of the test strip 3.

[0039] In the above installation of the test strip 3, the clamping part 4 needs to be manually adjusted before the test strip 3 can be installed between the limiting plate 106 and the clamping part 4, resulting in a more cumbersome installation process of the test strip 3 and being not convenient for improving the installation efficiency of the test strip 3. Therefore, in this embodiment, as Figure 6 、 Figure 7 and Figure 10 shown, the cross-section of the clamping part 4 is a right trapezoid. Among them, the clamping part 4 includes a guiding inclined surface 421, and a pressing plate 23 extending upward to the upper cover 1 is also fixedly provided on the lower cover 2.

[0040] Through the above settings, when the test strip 3 is installed, the dropping port 104 of the upper cover 1 is facing downwards, the upper cover 1 is placed horizontally, directly abut one side edge of the test strip 3 against the side wall of the limiting plate 106, and the other side edge is lapped on the guiding inclined surface 421 of the clamping part 4. Then press the lower cover 2 downwards, as Figure 7As shown, at this time, the pressing plate 23 abuts against the test strip 3, and then pushes down the tilted side of the test strip 3. At this time, under the separation and pushing of the test strip 3 on the guiding inclined surface 421, the clamping part 4 moves away from the test strip 3 and compresses the compression spring 53. When the engaging convex block 24 engages inside the engaging groove 105, the test strip 3 is in a horizontal state and abuts against the top wall of the upper cover body 1, restricting the movement of the test strip 3 and improving the stability of the test strip 3, solving the problems of different widths of the test strip 3, inconvenient positioning and installation of the test strip 3.

[0041] Since the clamping part 4 can move along the width direction of the clamping box, when the test strip 3 is relatively narrow, the test strip 3 cannot completely cover the observation slot 102, and it is easy to see the deficiencies of the test strip 3. Therefore, in this embodiment, as Figure 8 and Figure 10 shown, the clamping part 4 includes a sliding plate 41 and a clamping block 42. Among them, the sliding plate 41 is slidably connected to the top wall of the upper cover body 1, the clamping block 42 is fixedly installed on the sliding plate 41, the cross-section of the clamping block 42 is a right trapezoid, the test strip 3 is installed between the clamping block 42 and the limiting plate 106, and a clamping groove 43 is formed between the side wall of the clamping block 42 and the sliding plate 41. After the upper cover body 1 and the lower cover body 2 are encapsulated, the other side of the test strip 3 is located inside the clamping groove 43, thereby strengthening the stability of the test strip 3. Among them, a part of the opening of the observation slot 102 is blocked by the sliding plate 41 to avoid the defects caused by the narrow test strip 3.

[0042] When the test strip 3 is installed between the upper cover body 1 and the lower cover body 2, in order to enable the test strip 3 to accurately absorb the detection reagent entering from the dropping port 104, in this embodiment, as Figure 5 and Figure 9 shown, an extension tube 1041 aligned with the dropping port 104 is provided on the top wall of the upper cover body 1. Among them, a notch 1042 with an opening facing the test strip 3 is provided on the side wall of the extension tube 1041, and a blocking seat 21 aligned with the extension tube 1041 is fixedly provided on the lower cover body 2. When the upper cover body 1 and the lower cover body 2 are engaged, as Figure 9 shown, the blocking seat 21 is inserted into the inner cavity of the extension tube 1041 to block the bottom of the extension tube 1041 and prevent the detection reagent from leaking from the bottom of the extension tube 1041. However, at this time, the reagent dropped from the dropping port 104 contacts the test strip 3 from the notch 1042, and the test strip 3 completes the absorption of the reagent.

[0043] In order to strengthen the blocking effect on the extension tube 1041, in this embodiment, as Figure 6 、 Figure 7 and Figure 9As shown, a sealing ring 22 is sleeved on the peripheral wall of the plugging seat 21. Among them, the sealing ring 22 is made of rubber material. When the upper cover body 1 and the lower cover body 2 are buckled, the outer wall of the sealing ring 22 abuts against the inner wall of the extension pipe 1041, improving the sealing effect of the extension pipe 1041.

[0044] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
