Description

Technical Field

[0001] The utility model relates to the technical field of reagent strips, in particular to a reagent strip tray. Background Art

[0002] Reagents, also known as biochemical reagents or test drugs, are mainly pure chemicals used to achieve chemical reactions, analytical assays, research experiments, teaching experiments, and chemical formulations. Generally, they are classified into general reagents, high-purity reagents, analytical reagents, instrumental analysis reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion chromogenic reagents, etc. Reagents are usually stored in reagent bottles and transported using a tray; while reagent strips are produced in strip form for convenient use.

[0003] When using reagent strips, it is necessary to drip reagents onto the reagent strips and wait for a certain period of time to observe the color on the reagent strips, and then record the color. In actual use, it is usually necessary to drip different types of reagents onto a large number of reagent strips simultaneously to observe the colors on the reagent strips after dripping different reagents. After dripping is completed, the reagent strips after dripping usually need to be placed on a tray and wait for the reagent strips to react to record the colors on the reagent strips; during the waiting process, there will inevitably be some dust on the tray. Therefore, in the prior art (for example, the publication number is CN219215782U), a cover plate is usually added to the tray to prevent dust, but in actual use, the opening and closing method of the tray is relatively cumbersome, resulting in more time required for the operator to open or close the cover plate. For this reason, we propose a reagent strip tray to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a reagent strip tray, which has the advantage of being able to quickly open and close the cover plate, and solves the problem of the cumbersome opening and closing method of the cover plate.

[0005] To achieve the above object, the utility model provides the following technical solution: A reagent strip tray, comprising a tray body and a cover plate;

[0006] A cover plate handle is fixed on the top surface of the cover plate. A plurality of reagent strip bodies are placed inside the tray body. The tray body is a rectangle with a hollow interior and a missing top surface. A plurality of inclined accommodation holes are formed on the inner bottom surface of the tray body. The accommodation holes are adapted to the width of the reagent strip bodies. Two inclined plates are also fixed inside the accommodation holes. The inclined plates are slidably connected to the reagent strip bodies; A protection component is also provided on the tray body.

[0007] Further, the protection component includes long holes opened at both ends inside the tray body. Fixed springs are fixed to the left ends of the two long holes, and the other ends of the fixed springs are fixed with sliders. The left and right ends of the cover plate are respectively fixed between the two sliders.

[0008] The protection component further includes a fixed block fixed to the back surface of the tray body. A sliding rod is slidably connected inside the fixed block. A retaining ring is fixed to the outer surface of the sliding rod. An adjusting spring is fixed to the bottom surface of the retaining ring. The top end of the sliding rod is fixed with a first clamping block. A plurality of second clamping blocks are fixed to the bottom surface of the cover plate. A handle is fixed to the bottom surface of the sliding rod.

[0009] Further, the first clamping block is in the shape of ">", and the second clamping block is in the shape of "<".

[0010] Further, the adjusting spring is sleeved on the sliding rod, and the bottom surface of the adjusting spring is fixed to the top surface of the fixed block.

[0011] Further, a through groove is opened at the left end of the tray body, and the size of the through groove is adapted to the second clamping block.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] 1. For this reagent strip tray, by setting the protection component, when closing the cover plate, only need to pull down the handle. The handle drives the first clamping block to move downward, so that the first clamping block no longer fits with the second clamping block to stop limiting the cover plate. Further, under the elastic action of the two fixed springs, the two sliders are driven to move to the right. Since the two ends of the cover plate are fixed between the sliders, the cover plate will move to the right following the sliders, so as to achieve the purpose of closing the cover plate. Just by pulling down the handle, the limit on the second clamping block can be stopped, which is convenient for the operator to close the cover plate and improves the detection efficiency.

[0014] 2. When it is necessary to open the cover plate, only need to drive the cover plate to move to the left through the cover plate handle. By setting two corresponding inclined surfaces on the first clamping block and the second clamping block, when the first clamping block and the second clamping block collide, the first clamping block can be contracted downward through the two inclined surfaces, so that the cover plate moves to the left. In this way, the opened cover plate can be automatically limited after the cover plate is opened to an appropriate size. At the same time, when opening the cover plate, only need to pull the cover plate handle to open the cover plate.

[0015] 3. The reagent strip tray is provided with a plurality of accommodation holes on the tray body, and inclined plates are placed in two of the accommodation holes. When a reagent strip body needs to be placed, the reagent strip body can be inserted into the accommodation hole through the inclined plate, so that the reaction part at the left end of the reagent strip is located in the accommodation hole, avoiding contamination of the reaction part. The right end of the reagent strip is higher, and when taking out the reagent strip, it can be conveniently taken out through the right end of the reagent strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0023] Please refer to Figure 1 and Figure 2 , a reagent strip tray in this embodiment includes a tray body 1 and a cover plate 2; a through groove is provided at the left end of the tray body 1, a cover plate handle 3 is fixed on the top surface of the cover plate 2, a plurality of reagent strip bodies 4 are placed in the tray body 1, and the tray body 1 is a rectangular shape with a hollow interior and a missing top surface.

[0024] Please refer to Figure 3, in order to store the reagent strip body 4, a plurality of inclined receiving holes 5 are formed in the inner bottom surface of the tray body 1 in this embodiment. The receiving holes 5 are adapted to the width of the reagent strip body 4. Two inclined plates 6 are also fixed in the receiving holes 5, and the inclined plates 6 are slidably connected to the reagent strip body 4; a protection component is further provided on the tray body 1.

[0025] When storing the reagent strip body 4, first insert one end of the reagent strip body 4 into the receiving hole 5 through the two inclined plates 6. The reagent strip body 4 is lifted by the inclined plates 6, so that the left end of the reagent strip body 4 is located in the receiving hole 5 and the right end is located outside the receiving hole 5. Thus, the reaction area on the left end of the reagent strip body 4 can be protected, and at the same time, the reagent strip body 4 can be conveniently taken by the right end of the reagent strip body 4.

[0026] Please refer to Figure 4 , in order to prevent other interferences when the reagent strip body 4 reacts with the reagent, the protection component in this embodiment includes long holes opened at both ends inside the tray body 1. Fixed springs 8 are fixed at the left ends of the two long holes, and the other ends of the fixed springs 8 are fixed with sliders 7. The left and right ends of the cover plate 2 are respectively fixed between the two sliders 7.

[0027] The protection component further includes a fixed block 9 fixed on the back surface of the tray body 1. A sliding rod 10 is slidably connected inside the fixed block 9. A retaining ring 11 is fixed on the outer surface of the sliding rod 10. An adjusting spring 12 is fixed on the bottom surface of the retaining ring 11. The adjusting spring 12 is sleeved on the sliding rod 10, and the bottom surface of the adjusting spring 12 is fixed on the top surface of the fixed block 9. A first clamping block 13 is fixed at the top end of the sliding rod 10. The first clamping block 13 is in the shape of >. A plurality of second clamping blocks 14 are fixed on the bottom surface of the cover plate 2. The size of the through groove is adapted to the second clamping blocks 14. The second clamping blocks 14 are in the shape of <. A handle 15 is fixed on the bottom surface of the sliding rod 10.

[0028] When the reagent strip body 4 needs to be placed into the tray body 1, first drive the cover plate 2 to move leftward through the cover plate handle 3. By providing two corresponding inclined surfaces on the first clamping block 13 and the second clamping block 14, when the first clamping block 13 and the second clamping block 14 collide, the first clamping block 14 can be moved downward through the two inclined surfaces. When the first clamping block 13 moves downward, it will drive the sliding rod 10 fixed to the bottom surface of the first clamping block 13 to move downward. Further, the sliding rod 10 drives the retaining ring 11 fixed to its outer surface to move downward, so that the bottom surface of the retaining ring 11 presses the spring adjusting spring 12, causing the spring 12 to be compressed. By providing a plurality of second clamping blocks 14 on the bottom surface of the tray body 1, when the cover plate 2 moves leftward, the first clamping block 13 will repeatedly move downward under the elastic action of the adjusting spring 12. Further, when adjusted to an appropriate position, under the elastic action of the two fixed springs 8, drive the two sliders 7 to move rightward. When the two sliders 7 move, they will drive the cover plate 2 fixed between the two sliders 7 to move. When moving, the adjusting spring 12 will continuously apply an upward elastic force, so that the right end of the first clamping block 13 fits with the left end of the second clamping block 14, realizing the limit of the cover plate 2; thus driving the cover plate 2 to move leftward. This method can automatically limit the opened cover plate 2 after the cover plate 2 is opened to an appropriate size. At the same time, when opening the cover plate 2, only by pulling the cover plate handle 3 can the opening of the cover plate 2 be realized.
