Description

Technical Field

[0001] This utility model relates to the field of immunohistochemical staining technology, specifically to an immunohistochemical staining reagent rack. Background Technology

[0002] Immunohistochemical staining utilizes the specific binding reaction between antibodies and antigens. By labeling antibodies with signal amplification systems such as fluorescence and enzymes, the distribution of target proteins in cells and tissues can be observed under an optical microscope. Immunohistochemical staining requires the use of reagent racks, which provide an orderly space for storing and classifying various reagents, such as antibodies, substrates, and chromogenic agents.

[0003] Most existing immunohistochemical staining reagent racks adopt a double-layer design to accommodate more reagent bottles. However, a significant problem with this design is that the positions of the reagent bottles are fixed and cannot be adjusted according to actual needs. In particular, the reagent bottles on the upper layer are often difficult to access because of their height, requiring staff to stretch their arms or stand on tiptoe. This increases the difficulty and inconvenience of the operation. The fixed positions of the reagent bottles not only affect the efficiency of the staff, but also may cause the reagent bottles to tip over or break due to frequent inconvenience, resulting in reagent waste and laboratory safety hazards.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 As shown, an immunohistochemical staining reagent rack includes a support plate 1, and there are two support plates 1. An adjustment structure 2 is movably connected to the lower part of one side surface of the support plate 1. A rack plate 3 is fixed above the adjustment structure 2. A gear 4 is rotatably connected to the upper part of one side surface of the support plate 1. Mounting plates 5 are provided on the upper part of the opposite side surface of the support plate 1. A connecting shaft 6 is fixed to one side surface of the mounting plate 5. Movable plates 7 are rotatably connected to the upper and lower parts of the opposite side surface of the mounting plate 5. Connecting frames 8 are provided on the left and right sides of the bottom of the movable plates 7. A placement plate 9 is provided below the connecting frames 8. Several reagent placement slots 10 are opened on the top surface of the placement plate 9.

[0021] The adjustment structure 2 includes a motor 21, a lead screw 22, a fixing plate 23, and a lifting frame 24. The motor 21 is fixed to the lower part of one side surface of the support plate 1, the lead screw 22 is fixed to the top of the output shaft of the motor 21, the fixing plate 23 is fixed to one side surface of the support plate 1, and the top end of the lead screw 22 is rotatably connected to the bottom end of the fixing plate 23. The lifting frame 24 is slidably connected to one side surface of the support plate 1, and the lead screw 22 passes through the lifting frame 24 and is threadedly connected to the lifting frame 24. The bottom of the rack plate 3 is connected to the lifting frame 24. The top is fixedly connected, and a limiting groove 11 is opened on the lower side of one side surface of the support plate 1. A limiting block 12 is fixed on the lower side of one side surface of the lifting frame 24. The limiting block 12 is located inside the limiting groove 11 and is slidably connected to the inner wall of the limiting groove 11. When the motor 21 is turned on, the output shaft of the motor 21 will drive the lead screw 22 to rotate, and the limiting block 12 will slide inside the limiting groove 11 to limit the lifting frame 24, thereby allowing the lifting frame 24 to move up and down so that the position of the reagent bottle can be changed later.

[0022] The rack plate 3 meshes with the gear 4. One end of the connecting shaft 6 passes through the support plate 1 and is fixedly connected to the surface of the gear 4. The connecting shaft 6 is rotatably connected to the support plate 1. When the lead screw 22 drives the lifting frame 24 to move up and down, the rack plate 3 will drive the gear 4 to rotate, thereby causing the mounting plate 5 to rotate, thus changing the position of the upper and lower side placement plates 9 so that the staff can pick up the reagent bottles.

[0023] The connecting frame 8 is V-shaped, and the top of the connecting frame 8 is hinged to the bottom of the movable plate 7. The bottom of the connecting frame 8 is fixedly connected to the top of the placement plate 9. When the mounting plate 5 rotates, the connecting frame 8 can improve the stability of the movable plate 7 during movement and prevent the reagent bottle from moving.

[0024] An anti-slip pad 13 is attached to the bottom of the inner wall of the reagent placement tank 10. The anti-slip pad 13 is made of medical-grade silicone rubber, and the surface above the anti-slip pad 13 is provided with anti-slip texture. When the staff places the reagent bottle inside the reagent placement tank 10, the anti-slip pad 13 can improve the stability of the reagent bottle when it is placed and prevent the reagent bottle from moving during adjustment.

[0025] Working principle: When using the immunohistochemical staining reagent rack, the staff takes out the reagent bottles and places them one by one on the reagent placement slot 10. When the staff needs to retrieve the reagent bottles on the upper layer, they can turn on the motors 21 on both sides. The staff controls the rotation direction of the output shaft of the motors 21. At this time, the lifting frame 24 drives the rack plate 3 to descend, which in turn causes the gear 4 on the surface of the support plate 1 to rotate. The mounting plate 5 then rotates. When the mounting plate 5 rotates, the movable plate 7 also moves. After the mounting plate 5 flips, the positions of the movable plates 7 on the upper and lower sides are switched, and then the staff can retrieve the reagent bottles.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
