Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

The reagent strip storage device disclosed by the utility model is explained below with reference to the accompanying drawings, as shown in fig. 1 to fig. 3, the reagent strip storage device comprises an outer frame 1, the outer frame 1 is a rectangular frame formed by combining four side plates, at least one drawer 2 is arranged in the outer frame 1, the drawer 2 can be translated to the outer side of the outer frame 1, the drawer 2 is preferably a slide rail type drawer, the specific structure of the drawer is known in the art, and details are not described herein. At least one reagent strip tray limiting groove 21 is formed in the drawer 2, the reagent strip tray limiting groove 21 comprises a bottom plate, side plates located on two sides of the bottom plate and an inner end plate located at the inner end of the bottom plate, and one end (front end) of the reagent strip tray limiting groove 21 is open and used for inserting a reagent strip tray (not shown in the figure) into the reagent strip tray limiting groove 21 for storage.

In actual testing, there are often requirements that large-scale and multi-class tests need to be performed, and therefore, as shown in fig. 1 to fig. 3, the number of the drawers 2 is multiple, preferably at least three, and more specifically 10, and three reagent strip tray limiting grooves 21 are formed side by side on each drawer 2, so that the storage device can store 30 reagent strip trays simultaneously, and each reagent strip tray can contain a plurality of reagent strips, thereby greatly improving the storage capacity.

Usually, the width of each reagent strip tray limiting groove 21 is equivalent to the width of a reagent strip tray to ensure the stability of limiting, but this is inconvenient for placing the reagent strip tray into the reagent strip tray limiting groove 21, therefore, as shown in fig. 4, the outer frame 1 is provided with a guide groove 3 connected with the inlet end of each reagent strip tray limiting groove, the guide groove 3 comprises two guide blocks located at two sides of the inlet end of the reagent strip tray limiting groove 21, and a wedge-shaped groove-shaped space with a large opening end and a small inner end is formed between the two guide blocks. An indicator light 4 is arranged at the inlet of each guide groove 3, and the indicator light 4 is used for indicating whether a reagent strip tray exists in the corresponding reagent strip tray limiting groove 21.

Although the addition of the guide grooves 3 can reduce the difficulty of inserting the reagent strip trays, the drawer 2 can be opened by the pushing force when the reagent strip trays are inserted into each reagent strip tray limiting groove 21, which is obviously disadvantageous for the operation of placing the reagent strip trays. Therefore, as shown in fig. 1, 3, and 5, the outer frame 1 is further provided with a first limiting mechanism 5 having a power source for at least limiting the opening of the drawer 2, so that the drawer can be effectively prevented from being opened when the reagent strip tray is inserted into the reagent strip tray limiting groove 21, and when the reagent strip tray is inserted and then needs to be opened, the first limiting mechanism 5 automatically releases the limitation of the opening operation of the drawer 2, so that the drawer containing the reagent strip tray can be opened to perform corresponding operations.

Since there are a plurality of drawers 2, it is necessary to limit the opening of each drawer 2 when the reagent strip tray is inserted, and in this embodiment, the opening of all the drawers 2 is limited by the first limiting mechanism 5. The specific structure of the first limiting mechanism 5 will be described in detail, as shown in fig. 1 and 5, which comprises a power source 51 capable of generating a linear movement in the vertical direction Z, said power source 51 being an air or hydraulic cylinder or a linear movement device driven by an electric motor, the power source 51 is connected to a vertical rod 52 driven by the power source to move at a first height and a second height, the side of the vertical rod 52 is formed with a stop block 54 corresponding to the projection 53 of each side of the drawer 2, at a first height, the stop block 54 is located in front of the projection 53 of the drawer 2 in the closed state (defining that during the opening process of the drawer 2, the position where the drawer passes through first is the rear position, and the position where the drawer passes through later is the front position), namely, the blocking block 54 is located on the moving path of the opening of the projection 53, so that the projection 53 is blocked by the blocking block 54 when being opened and cannot be opened continuously; at the second height, the stop 54 is vertically offset from the projection 53, so that the stop 54 does not block the movement of the projection 53.

In order to ensure the movement stability of the vertical rod 52, a guide post (not shown in the figure) is arranged on the bracket, and the guide post is inserted into a waist-shaped hole extending in the vertical direction on the vertical rod 52; as shown in fig. 1, the vertical rod 52 is connected to a cross rod 55 perpendicular thereto, the cross rod 55 is connected to the power source 51, two guide sleeves 56 are disposed on the cross rod 55, a guide shaft 57 extending in the vertical direction is inserted into each of the two guide sleeves 56, and the guide shaft 57 is fixed to the outer frame 1.

Of course, in other embodiments, the stop block 54 of the first limiting mechanism can cooperate with the second protrusion to prevent the drawer from closing.

Further, an openable and closable door (not shown in the figure) for at least covering all the drawers is further arranged on the outer frame 1, the door and the drawer in an opened state are located on the opposite side of the outer frame, the openable and closable door is used for being opened when reagent strips are added, and the door is closed after the reagent strips are placed in the reagent strip tray limiting groove 21, and the door can be an automatic door or a manual door, and the specific structure of the door is known technology, and is not described herein.
