[0002] Hematoxylin stain is a natural dye extracted from logwood. After being oxidized, this dye forms hematoxylin, which has excellent staining properties and is especially suitable for staining tissues and cells. To facilitate hematoxylin staining operations for researchers and medical staff, a variety of hematoxylin staining reagent kits have been introduced on the market. These reagent kits usually contain all the reagents and tools required for hematoxylin staining, such as hematoxylin staining solution, differentiating solution, bluing solution, eosin staining solution (used for staining cytoplasm, forming a sharp contrast with hematoxylin), and necessary auxiliary materials.

[0003] The placement cavity design of traditional reagent kits is relatively simple, usually relying only on gravity or a simple card slot structure to fix reagent bottles. Due to the lack of fixation, reagent bottles are prone to loosening or even falling off during transportation, vibration, or operation, which may not only cause damage to reagent bottles due to collision but also cause reagent leakage, affecting the accuracy and safety of experimental results.

[0004] Therefore, we propose a hematoxylin staining reagent kit to solve the above problems. Content of the Utility Model

Detailed Embodiment

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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.

[0034] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings in the specification and specific embodiments.

[0035] Refer toFigure 1-3 , a hematoxylin staining kit, including a box body 1, a sealing plate 2 is installed on the box body 1, and a plurality of object placing cylinders 3 for placing reagent bottles are evenly distributed on the sealing plate 2. The design of the plurality of object placing cylinders 3 enables the kit to accommodate multiple reagents simultaneously, facilitating classified storage and retrieval, improving the space utilization efficiency. A quick-fixing component is correspondingly arranged on the object placing cylinder 3, which can quickly fix the reagent bottle to ensure that the reagent bottle is stable and does not shake during use, reducing the risk of reagent leakage caused by the dropping or tilting of the reagent bottle.

[0036] The quick-fixing component includes a mounting post 4, a sliding cylinder 5, a support plate 6, a pressing locking mechanism 7 and a clamping mechanism 8. After the reagent bottle is placed in the object placing cylinder 3, by pressing on the reagent bottle, the reagent bottle moves into the object placing cylinder 3 and is completely placed in the object placing cylinder 3 and clamped and fixed under the action of the pressing locking mechanism 7. When retrieving the reagent bottle, press the reagent bottle again to make the reagent bottle pop outwards and release the fixation, which is convenient for taking and placing, improving the operation convenience.

[0037] The mounting post 4 is fixedly installed at the inner bottom of the box body 1, and the mounting post 4 is coaxially arranged with the object placing cylinder 3.

[0038] The sliding cylinder 5 is slidably sleeved on the mounting post 4, and a spring 51 is arranged between the sliding cylinder 5 and the box body 1. The spring 51 is a compression spring, and the elastic force of the spring 51 makes the sliding cylinder 5 tend to move upwards. A convex platform is arranged at the top of the mounting post 4, and a limiting ring is arranged at the bottom of the sliding cylinder 5. The outer diameter of the convex platform is larger than the inner diameter of the limiting ring. Through the cooperation of the convex platform and the limiting ring, the sliding cylinder 5 can be limited to prevent the sliding cylinder 5 from separating from the mounting post 4.

[0039] Refer to Figure 2-4 , the support plate 6 is threadedly installed on the sliding cylinder 5. An axially installed threaded sleeve 52 is arranged at the top of the sliding cylinder 5, and a threaded rod 61 that is threadedly matched with the threaded sleeve 52 is fixedly installed at the bottom of the support plate 6. By rotating the support plate 6, the height of the support plate 6 can be adjusted so that the support plate 6 can match reagent bottles of different heights. When the reagent bottle is placed, the bottle mouths of reagent bottles of different heights can all be flush with the sealing plate 2, avoiding the short reagent bottle being placed too deep during fixation and being inconvenient to take, and also avoiding the long reagent bottle having its bottle mouth exceeding the sealing plate 2 too much during fixation, resulting in poor protection effect.

[0040] Refer to Figure 1-5, pressing the locking mechanism 7 can quickly switch the height position of the sliding cylinder 5 by pressing. The clamping mechanism 8 is used for laterally clamping and fixing the reagent bottle. By continuously pressing the reagent bottle, under the action of the pressing locking mechanism 7, the sliding cylinder 5 can alternately be in the high position and the low position. When the sliding cylinder 5 is in the low position, the reagent bottle is completely placed in the placing cylinder 3, and the clamping mechanism 8 clamps and fixes the reagent bottle, achieving a good protection effect. When the sliding cylinder 5 is in the high position, the clamping mechanism 8 releases the clamping and fixing of the reagent bottle, and the body of the reagent bottle extends beyond the placing cylinder 3, facilitating the taking and placing of the reagent bottle and improving the operation convenience.

[0041] Refer to Figure 1-5 , the pressing locking mechanism 7 includes a rotating ring 71 rotatably arranged on the sliding cylinder 5. A serrated groove 72 extending around the rotating ring 71 is formed on the outer peripheral surface of the rotating ring 71. A plurality of vertical rods 73 are fixedly installed at the bottom of the box body 1, and a guiding column 74 cooperating with the serrated groove 72 is arranged at the top of the vertical rod 73. The sliding cylinder 5 tends to move upward under the action of the spring 51. When pressing the reagent bottle, the sliding cylinder 5 moves downward with the extrusion of the reagent bottle, so that the guiding column 74 cooperates with the serrated groove 72. During the up and down movement of the sliding cylinder 5, the guiding column 74 cooperates with different positions of the serrated groove 72, enabling the sliding cylinder 5 to stay at intervals in the low position and the high position.

[0042] Refer to Figure 2-5 , the serrated groove 72 includes an upper tooth surface and a lower tooth surface. Among them, the cooperation between the guiding column 74 and the upper tooth surface can control the rotation of the rotating ring 71, enabling the guiding column 74 to cooperate with different positions of the serrated groove 72. The cooperation between the guiding column 74 and the lower tooth surface can control the upper limit position of the sliding cylinder 5, enabling the sliding cylinder 5 to stay at different height positions.

[0043] The upper tooth surface includes a plurality of continuous inclined tooth grooves 75. Concave points 751 are formed at the bent parts of the inclined tooth grooves 75, and convex points 752 are formed at the connection parts of adjacent two inclined tooth grooves 75. When the guiding column 74 abuts against the side wall of the inclined tooth groove 75, it will drive the rotating ring 71 to rotate and stop when the guiding column 74 reaches the concave point 751; the lower tooth surface includes a plurality of continuous reverse inclined grooves 76. Groove points 761 are formed at the bent parts of the reverse inclined grooves 76. Axially arranged downward extending long grooves 762 are formed at the groove points 761 at interval positions. When the guiding column 74 abuts against the side wall of the reverse inclined groove 76, it will drive the rotating ring 71 to rotate and stop when the guiding column 74 reaches the groove point 761 or the bottom of the long groove 762. When the guiding column 74 reaches the groove point 761, the upward movement distance of the sliding cylinder 5 is shorter, and at this time the sliding cylinder 5 is in the low position. When the guiding column 74 reaches the bottom of the long groove 762, the upward movement distance of the sliding cylinder 5 is longer, and at this time the sliding cylinder 5 is in the high position.

[0044] The anti-slotted grooves 76 correspond to the helical grooves 75 one by one, and the number of anti-slotted grooves 76 is the same as that of the helical grooves 75. Moreover, the positions of the concave points 751 and convex points 752 on the upper tooth surface are circumferentially misaligned with the positions of the groove points 761 and long grooves 762 on the lower tooth surface. Specifically, taking the initial state where the sliding cylinder 5 is at a high position and no reagent bottle is placed in the storage cylinder 3 as an example, at this time, the guide post 74 is located at the bottom of the long groove 762. Place the reagent bottle into the storage cylinder 3 and press it, causing the sliding cylinder 5 to move downward. The guide post 74 abuts against the side wall of the helical groove 75 and drives the rotating ring 71 to rotate until the guide post 74 reaches the concave point 751 and stops. When the rotating ring 71 rotates, the position of the longitudinal projection of the guide post 74 reaches the adjacent anti-slotted groove 76. After releasing the hand, the spring 51 rebounds, and the sliding cylinder 5 returns upward. The guide post 74 abuts against the side wall of the anti-slotted groove 76 and drives the rotating ring 71 to rotate and stops when the guide post 74 reaches the groove point 761, making the sliding cylinder 5 at a low position and the reagent bottle completely enter the storage cylinder 3. Due to the rotation of the rotating ring 71, the position of the longitudinal projection of the guide post 74 crosses the convex point 752 and reaches the adjacent helical groove 75. When pressing the reagent bottle again to make the sliding cylinder 5 move downward, the above process is repeated, and the guide post 74 finally stops at the bottom of the long groove 762 at the adjacent position, making the sliding cylinder 5 at a high position and the reagent bottle pop out, facilitating taking and placing.

[0045] Referring to Figure 3 and 6 , the clamping mechanism 8 includes a plurality of mounting ears installed on the side wall of the storage cylinder 3. A rotating shaft 81 is rotatably arranged on the mounting ears. A gear transmission structure is arranged between the rotating shaft 81 and the sliding cylinder 5, which drives the rotating shaft 81 to rotate when the sliding cylinder 5 moves up and down. And a clamping piece 82 is fixedly arranged on the rotating shaft 81. An opening corresponding to the clamping piece 82 is formed on the side of the storage cylinder 3. The clamping piece 82 can extend into the storage cylinder 3 through the opening. The clamping piece 82 is in a spiral shape. Therefore, the outer peripheral surface of the clamping piece 82 gradually expands outward. The rotation of the rotating shaft 81 drives the clamping piece 82 to rotate, making the clamping piece 82 gradually press against the reagent bottle. Fixing and loosening are realized by the forward and reverse rotation of the rotating shaft 81. And the clamping piece 82 is an elastic piece with a rubber coating. When the clamping piece 82 presses against the reagent bottle, buffering can be realized through the elasticity of the clamping piece 82, and the rubber coating can increase the frictional resistance and reduce the risk of the reagent bottle slipping and shifting relative to the clamping piece 82.

[0046] Referring to Figure 3 , the gear transmission structure includes a gear 83 fixedly arranged on the rotating shaft 81. A toothed rod 84 is fixedly arranged on the side wall of the sliding cylinder 5. The toothed rod 84 meshes with the gear 83. The toothed rod 84 moves along with the sliding cylinder 5. When the sliding cylinder 5 moves downward, the clamping piece 82 rotates forward to realize clamping until the sliding cylinder 5 is at a low position to achieve fastening. When the sliding cylinder 5 moves upward, the clamping piece 82 rotates reversely to realize loosening, and the sliding cylinder 5 is no longer fixed when it is at a high position.

[0047] Working principle:

[0048] In the initial state, the sliding cylinder 5 is at a high position, and no reagent bottle is placed in the storage cylinder 3. At this time, the guide post 74 is located at the bottom of the long groove 762. Place the reagent bottle into the storage cylinder 3 and press it, causing the sliding cylinder 5 to move downward. The guide post 74 abuts against the side wall of the helical tooth groove 75 and drives the rotating ring 71 to rotate until the guide post 74 reaches the concave point 751 and stops. When the rotating ring 71 rotates, the position of the longitudinal projection of the guide post 74 reaches the adjacent reverse helical groove 76. After releasing the hand, the spring 51 rebounds, and the sliding cylinder 5 returns upward. The guide post 74 abuts against the side wall of the reverse helical groove 76 and drives the rotating ring 71 to rotate and stops when the guide post 74 reaches the groove point 761, making the sliding cylinder 5 at a low position, and the reagent bottle completely enters the storage cylinder 3. The downward movement of the sliding cylinder 5 causes the clamping piece 82 to rotate forward to realize clamping until the sliding cylinder 5 is at a low position to achieve fastening;

[0049] Due to the rotation of the rotating ring 71, the position of the longitudinal projection of the guide post 74 crosses the convex point 752 and reaches the adjacent helical tooth groove 75. When the reagent bottle is pressed again to make the sliding cylinder 5 move downward, the above process is repeated, and the guide post 74 finally stops at the bottom of the long groove 762 at the adjacent position, making the sliding cylinder 5 at a high position. The upward movement of the sliding cylinder 5 causes the clamping piece 82 to rotate in the reverse direction to realize loosening. When the sliding cylinder 5 is at a high position, it is no longer fixed, and the reagent bottle pops out outward, facilitating taking and placing.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
