Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a staining rack for laboratory use. Background Technology

[0002] Microbial smears, blood cell smears, and bone marrow smears in the laboratory all need to be stained for observation, and then dried or stored using a staining rack.

[0003] Currently, biological smear staining racks have the following problems: Existing racks have a compact design, with adjacent biological smears typically spaced 10mm apart. When many biological smears are placed on the rack, it is inconvenient to observe the drying process of individual smears or to handle them. Furthermore, when different types of biological smears are placed on the rack simultaneously, it becomes difficult to accurately locate the smears, especially over long periods or with a large number of samples. Utility Model Content

[0004] The present invention aims to provide a staining rack for laboratory use, in order to solve the problem that the existing staining racks have a compact structure, which makes it inconvenient to observe the drying of individual biological smears and to handle biological smears.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A staining rack for laboratory use includes a base, a rotating cylinder, glass holders, and a lifting mechanism. The rotating cylinder is axially connected to the center of the base. Several glass holders arranged in a circle are connected around the rotating cylinder via lifting slide rails. The lifting mechanism is mounted on the base and includes a lifting frame and a control mechanism. The control mechanism controls the raising and lowering of the lifting frame. The lifting frame is detachably connected to the bottom of the glass holders to lift individual glass holders.

[0007] Furthermore, the lifting frame includes a top rod, a bottom rod, and an X-shaped folding rod. The bottom rod is fixed to the bottom of the recessed receiving space of the base. The top rod and the bottom rod are connected vertically by the X-shaped folding rod. One end of the top rod and the bottom rod are respectively fixedly hinged to one end of the X-shaped folding rod. The ends of the top rod and the bottom rod away from the fixed hinge are provided with a sliding groove. A first slider is installed in the sliding groove of the top rod, and a second slider is installed in the sliding groove of the bottom rod. The first slider and the second slider are both hinged to the ends of the X-shaped folding rod away from the fixed hinge. The second slider is controlled to slide by a control mechanism.

[0008] The control mechanism includes a raised console located on the edge of the base, on which a button is mounted. The button is connected to a first hydraulic piston of a first hydraulic cylinder via a first connecting rod. The first hydraulic cylinder is connected to a second hydraulic cylinder via a hydraulic pipe. The second hydraulic piston of the second hydraulic cylinder is connected to a second slider via a second connecting rod.

[0009] Furthermore, the base has an inwardly recessed cavity on its side, and a dyeing and washing rack is slidably connected inside the cavity. The dyeing and washing rack is slidably stored or slid out relative to the cavity, and a drainage hole is provided at the bottom of the dyeing and washing rack.

[0010] Furthermore, both the raised control console and the end of the fixed glass frame furthest from the rotating cylinder are equipped with magnets.

[0011] Furthermore, the glass mounting frame is U-shaped, and both ends of the glass mounting frame are provided with grooves to facilitate the insertion of glass slides.

[0012] Furthermore, a spring is installed between the bottom of the button and the raised console.

[0013] Furthermore, a sequence label is provided on the top of the rotating cylinder, and the sequence label has a one-to-one correspondence with several of the surrounding glass mounting frames.

[0014] Furthermore, the top rod and the bottom of the glass frame are fitted with a mortise and tenon structure that forms a clearance fit.

[0015] Furthermore, the base is provided with drainage holes.

[0016] The principles and beneficial effects of this technical solution are at least as follows:

[0017] 1. This utility model features a glass slide holder connected to a rotating cylinder via a lifting slide rail. Rotating the rotating cylinder causes the glass slide holder to rotate onto the lifting mechanism. The lifting mechanism controls the lifting of the glass slide holder, raising it upwards along the lifting slide rail and separating it from other glass slide holders arranged closely around the circumference. This facilitates the observation of biological smears on a single glass slide holder without removing the glass slide, simplifying the observation process. At the same time, raising a single glass slide holder also makes it easier to retrieve or store the biological smear, preventing damage to surrounding biological smears due to improper operation during retrieval.

[0018] 2. This utility model also has sequential labels on the rotating cylinder that correspond one-to-one with the glass holders. By numbering the glass holders in the circumferential array, the specific position of the biological smear is recorded, which facilitates the subsequent observation or removal of specific biological smears and solves the problem of inconvenient accurate positioning of biological smears.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0025] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0026] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, or component, but does not exclude the presence or addition of one or more other features, elements, or components.

[0027] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0028] refer to Figures 1 to 3A staining rack for laboratory use includes a base 1, a rotating cylinder 2, a glass holder 4, and a lifting mechanism 3. The rotating cylinder 2 is axially connected to the center of the base 1. Several glass holders 4 arranged in a circle are connected around the rotating cylinder 2 by lifting slide rails 5. The lifting mechanism 3 is set on the base 1 and includes a lifting frame 31 and a control mechanism 32. The control mechanism 32 controls the raising and lowering of the lifting frame 31. The lifting frame 31 is detachably connected to the bottom of the glass holder 4 to lift a single glass holder 4. This invention features a glass slide holder 4 connected to a rotating cylinder 2 via a lifting slide rail 5. Rotating the rotating cylinder 2 causes the glass slide holder 4 to rotate onto the lifting mechanism 3. The lifting mechanism 32 controls the lifting frame 31 to lift the glass slide holder 4 upwards along the lifting slide rail 5, thus separating it from other closely arranged glass slide holders 4 around the circumference. This facilitates the observation of biological smears on a single glass slide holder 4 without removing the slide, simplifying the observation process. At the same time, lifting a single glass slide holder 4 also makes it easier to pick up or store the biological smear, preventing damage to surrounding biological smears due to improper operation during handling.

[0029] Example 1

[0030] Specifically, the lifting frame 31 includes a top rod 311, a bottom rod 312, and an X-shaped folding rod 313. The bottom rod 312 is fixed to the bottom of the recessed receiving space of the base 1. The top rod 311 and the bottom rod 312 are connected vertically by the X-shaped folding rod 313. One end of the top rod 311 and the bottom rod 312 are respectively fixedly hinged to one end of the X-shaped folding rod 313. The ends of the top rod 311 and the bottom rod 312 away from the fixed hinge are provided with a sliding groove 314. A first slider 315 is installed in the sliding groove 314 of the top rod 311, and a second slider 316 is installed in the sliding groove 314 of the bottom rod 312. The first slider 315 and the second slider 316 are both hinged to the ends of the X-shaped folding rod 313 away from the fixed hinge. The second slider 316 is controlled to slide by the control mechanism 32.

[0031] The control mechanism 32 controls the left and right sliding of the slider to raise or lower the top rod 311 by the X-shaped folding rod 313, thereby realizing the lifting function. When the top rod 311 is lowered, it can be completely stored in the recessed space of the base 1 without affecting the rotation of the several sequentially arranged glass shelves 4 on the base 1.

[0032] The control mechanism 32 includes a raised console 321 located on the edge of the base 1. A button 322 is mounted on the raised console 321. The button 322 is connected to the first hydraulic piston 325 of the first hydraulic cylinder 324 via a first connecting rod 323. The first hydraulic cylinder 324 is connected to a second hydraulic cylinder 327 via a hydraulic pipe 326. The second hydraulic piston 328 of the second hydraulic cylinder 327 is connected to a second slider 316 via a second connecting rod 329. Pressing the button 322 transmits force to the first hydraulic piston 325 via the first connecting rod 323. The first hydraulic piston 325 forces the hydraulic medium from the first hydraulic cylinder 324 into the second hydraulic cylinder 327 via the hydraulic pipe 326, pushing the second hydraulic piston 328 to slide. The second hydraulic piston 328 then transmits the force to the second slider 316, causing the second slider 316 to slide to the right (see reference). Figure 2 (direction), to achieve lifting control of the lifting frame 31.

[0033] A spring 7 is installed between the bottom of button 322 and the raised control panel 321. When the panel is raised, pressing button 322 compresses spring 7. After the button is released, button 322 rebounds under the action of spring 7, and the above-mentioned raising control process is reversed, causing the second slider 316 to slide to the left (see reference). Figure 2 The direction of descent is controlled by a hydraulic system, which minimizes impact and makes the descent smoother. It is worth noting that this process can also be achieved in other similar ways, such as by placing a spring 7 between the second slider 316 and the second slide groove 314 to allow the second slider 316 to slide to the left, thus controlling the descent of the lifting frame 31. This does not affect the implementation of this invention.

[0034] Example 2

[0035] As another embodiment of this utility model, the side of the base 1 can also be provided with an inwardly recessed cavity, and a dyeing and washing rack 10 is slidably connected in the cavity. The dyeing and washing rack 10 is slidably stored or slid out relative to the cavity. After the dyeing and washing rack 10 is slid out relative to the cavity, it forms a platform for dyeing or rinsing. The platform is suspended above the sink, and then the biological smear that needs to be titrated and stained is placed on it for the burning or rinsing steps. The bottom of the dyeing and washing rack 10 is provided with a drain hole 11 so that the rinsing water or dyeing waste liquid falls naturally into the sink. This utility model, by setting a retractable dyeing and washing rack 10, can facilitate researchers to perform titration staining and rinsing steps. It is practical and convenient. It is worth noting that the dyeing and washing rack 10 can be connected to the cavity on the side of the base 1 through a slide rail or other sliding device, and the dyeing and washing rack 10 can be folded, telescopically slid or directly slid out.

[0036] Example 3

[0037] In another embodiment of this utility model, magnets 6 are provided at the ends of the raised control console 321 and the glass holder 4 away from the rotating cylinder 2. The magnets 6 attract each other, which can keep the glass holder 4 always in line with the raised control console 321, thereby fixing the position of the glass holder 4 that is about to be raised. This ensures that the lifting frame 31 at the bottom is always in the correct position to lift the glass holder 4, preventing lifting failure due to angular misalignment between the lifting frame 31 and the glass holder 4. It is worth noting that the method of fixing the position of the glass holder 4 in this embodiment can also be achieved in other ways, such as installing a ratchet mechanism at the bearing position where the rotating cylinder 2 and the base 1 are axially connected, so that the rotating cylinder 2 rotates at a fixed angle each time, thereby fixing the position of the glass holder 4. This does not affect the implementation of this utility model.

[0038] Example 4

[0039] Specifically, the glass holder 4 is U-shaped, and both ends of the glass holder 4 are provided with grooves 41 for easy insertion of glass slides. By inserting both ends of the glass slide into the grooves 41 respectively, the glass slide is fixed, and the glass slide and the grooves 41 form a clearance fit.

[0040] Example 5

[0041] Specifically, the top of the rotating cylinder 2 is equipped with sequential labels 8, which correspond one-to-one with several surrounding glass holders 4. By numbering the circular array of glass holders 4, the specific location of the biological smears is recorded, facilitating subsequent observation or retrieval of specific biological smears and solving the problem of inaccurately locating the biological smears. By recording the biological smears and their corresponding numbers after storage, the required biological smears can be quickly located.

[0042] Example 6

[0043] Specifically, the top rod 311 and the bottom of the glass-fixed frame 4 are fitted with a mortise and tenon structure 9 that provides a clearance fit, allowing the bottom of the lifting frame 31 and the glass-fixed frame 4 to be detachably connected. When rising, the mortise and tenon structure 9 engages to ensure a stable connection between the top rod 311 and the glass-fixed frame 4, preventing instability during the lifting process. Clearly, the two can be detachably connected, and this connection is not limited to the method described in this embodiment.

[0044] Example 7

[0045] Specifically, the base 1 is provided with drainage holes 11 to make the biological smears easier to dry.
