Description

Technical Field

[0001] This utility model relates to the field of medical testing tools, and more specifically, to a glass slide staining rack. Background Technology

[0002] In fields such as medical testing, microbiology research, and pathological analysis, it is often necessary to stain samples on glass slides to facilitate observation and analysis under a microscope. For example, in clinical diagnosis, staining slides containing samples such as blood, sputum, and tissue sections helps doctors observe cell morphology, structure, and characteristics of pathogens, thereby aiding in disease diagnosis.

[0003] Traditional slide staining racks are mostly designed to hold slides horizontally. After staining, water and staining solution tend to accumulate on the slides, leading to prolonged drying time. Since slides can only be examined under a microscope after drying, this affects the detection efficiency. Furthermore, the staining rack does not securely hold the slides, which can easily cause them to fall off during the staining process, thus affecting the detection results.

[0004] Therefore, there is an urgent need for a technology to replace the existing slide staining rack in order to solve the problem of how to stain slides efficiently and stably. Utility Model Content

[0005] In view of this, the present invention proposes a slide staining rack, which aims to solve the problem of how to stain slides efficiently and stably.

[0013] Furthermore, both the elastic connecting component and the movable component are provided in two sets. The movable cavities at both ends are respectively sleeved on the sides of the first connecting rods of the two sets of elastic connecting components. The movable cavities are slidably connected to the first connecting rods. The first return spring is disposed inside the movable cavity. The two sets of movable components are correspondingly arranged. The length of the movable plate is longer than the length of the movable cavity. The sum of the lengths of the two sets of movable plates exceeding the length of the movable cavity is equal to the length of the connecting block. The width of the movable plate is half of the movable cavity.

[0014] Furthermore, both sets of connecting blocks are provided with slide pressing assemblies on the sides near the movable plate. Each slide pressing assembly is provided with a second connecting rod, and a second return spring is sleeved on the side of the second connecting rod. A slide pressing plate is provided at the end of the second connecting rod away from the connecting block. The slide pressing plate is L-shaped and is positioned above the movable plate and in contact with it. The slide pressing plate is slidably connected to the second connecting rod, and a gap is provided between the slide pressing plate and the movable cavity.

[0015] Furthermore, limiting components are provided on both sides of the dyeing tank assembly fixing plate, and each limiting component is equipped with a limiter. The limiter has a through hole and a limiting cavity inside, and a second limiting block is provided inside the limiting cavity. The second limiting block is fixedly connected to the dyeing tank assembly fixing plate, and a second slide rail is provided between the limiting block and the dyeing tank assembly fixing plate. The outer side of the limiter is connected to the second slide rail. A third connecting rod is provided on the side of the second limiting block near the first slide rail, and a third return spring is sleeved on the side of the third connecting rod. The position of the third connecting rod corresponds to the through hole.

[0016] Furthermore, the limiter is provided with a positioning hole on the side near the dyeing tank assembly fixing plate, and a positioning rod is provided on the dyeing tank assembly fixing plate in the direction corresponding to the positioning hole. A connecting piece is sleeved on the side of the positioning plate, the connecting piece is slidably connected to the positioning rod, the connecting piece is fixedly connected to the dyeing tank assembly fixing plate, and a push rod is provided at the end of the positioning rod away from the limiter.

[0017] Furthermore, the support plate includes an upper support plate, a middle support plate, and a lower support plate. The middle support plate is inclined, and there is a height difference between the upper and lower support plates. A support column is connected to the lower surface of the upper support plate. The upper and middle support plates are hinged, and the lower and middle support plates are hinged. A baffle is provided on the side of the lower support plate except for the surface connected to the middle support plate. A push plate is slidably connected to the lower surface of the lower support plate. A hydraulic mechanism is provided below the push plate. The hydraulic mechanism is fixedly connected to the bottom of the receiving chamber.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The interior of the enclosure features a storage compartment, providing a relatively enclosed and well-organized space for the overall staining operation. The staining support frame is placed within the storage compartment and connected to the support plate via support columns, forming a stable support structure. This layout allows the staining tank assembly fixing plate to slide on the support plate, facilitating flexible adjustment of the staining tank assembly's position according to actual needs and achieving efficient space utilization. Furthermore, the staining tank assembly consists of several retractable staining tanks, allowing for flexible adjustment of the number and size of the staining tanks based on the number of slides and experimental requirements, greatly enhancing the adaptability of the staining rack to different experimental scales.

[0023] 2. The design of the expandable staining tank helps optimize the staining process. During staining, the staining tank can be adjusted to a suitable size according to the length and shape of the slide, ensuring that the staining solution can evenly cover the slide. This avoids waste of staining solution or uneven staining caused by the staining tank being too large or too small, thereby improving the accuracy of experimental results. At the same time, the relatively enclosed environment of the chamber reduces the interference of external factors on the staining process, such as dust and airflow, further ensuring the stability of staining quality.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] See Figure 1 As shown, this embodiment provides a slide staining rack, including a box body 100, which has a receiving compartment 110 inside;

[0040] A dyeing support frame 400 is installed inside the receiving chamber 110. The dyeing support frame 400 is provided with a support column 420. The upper end of the support column 420 is connected to a support plate 410, and the lower end of the support column 420 is fixedly connected to the bottom of the receiving chamber 110.

[0041] The dyeing tank assembly fixing plate 300 is mounted on the support plate 410. The lower surface of the dyeing tank assembly fixing plate 300 is slidably connected to the upper surface of the support plate 410. A first slide rail 310 is provided in the middle of the upper surface of the dyeing tank assembly fixing plate 300.

[0042] The dyeing tank assembly is mounted on the first slide rail 310 and consists of several retractable dyeing tanks 200 arranged together.

[0043] As described above, during staining, the slides to be stained are first placed in the retractable staining tank 200 within the staining tank assembly. The retractable state of the staining tank 200 can be adjusted according to the number and size of the slides to accommodate their dimensions and ensure they are securely placed within the staining tank. The staining tank assembly is then slid along the first slide rail 310 in the middle of the upper surface of the staining tank assembly fixing plate 300, moving the assembly to a suitable position according to the actual staining requirements.

[0044] See Figures 2-4 As shown, the retractable dyeing tank 200 includes: an elastic connection assembly 210 and a movable assembly 220;

[0045] The elastic connection component 210 includes a connecting block 211, with a first connecting rod 212 on both sides of the connecting block 211. A first limiting block 214 is provided at the end of the first connecting rod 212 away from the connecting block 211, and a first return spring 213 is sleeved on the side of the first connecting rod 212.

[0046] The movable component 220 has movable cavities 222 at its upper and lower ends, and a movable plate 221 is disposed between the movable cavities 222.

[0047] Specifically, both the elastic connecting component 210 and the movable component 220 are provided in two sets. The movable cavities 222 at both ends are respectively sleeved on the sides of the first connecting rod 212 of the two sets of elastic connecting components 210. The movable cavity 222 is slidably connected to the first connecting rod 212. The first return spring 213 is provided inside the movable cavity 222. The two sets of movable components 220 are correspondingly arranged. The length of the movable plate 221 is longer than the length of the movable cavity 222. The sum of the lengths of the two sets of movable plates 221 beyond the length of the movable cavity 222 is equal to the length of the connecting block 211. The width of the movable plate 221 is half of the movable cavity 222.

[0048] Understandably, the slides to be stained are placed on the movable plate 221 of the retractable staining tank 200. Since the movable plate 221 is the part of the retractable staining tank 200 that carries the slides, and the width of the movable plate 221 is half that of the movable cavity 222, this design allows the movable plate 221 to be better stored in the movable cavity 222 when not in use, while providing sufficient carrying area when in use.

[0049] As can be seen from the above, depending on the size of the slide, the telescopic state of the retractable staining tank 200 may need to be adjusted. Initially, the two sets of movable components 220 are positioned appropriately on the elastic connecting component 210, and the first return spring 213 is in its natural state. When it is necessary to enlarge the size of the staining tank to accommodate a larger slide, the two sets of movable components 220 are pulled outwards. Since the movable cavity 222 is slidably connected to the first connecting rod 212, the movable component 220 can slide along the first connecting rod 212. During the pulling process, the first return spring 213 is compressed, generating an outward thrust. When the movable component 220 slides to the appropriate position, causing the portion of the movable plate 221 extending beyond the movable cavity 222 to join together to form a sufficiently large bearing surface, the pulling stops.

[0050] Specifically, both sets of connecting blocks 211 are provided with glass slide pressing assemblies 230 on the sides near the movable plate 221. The glass slide pressing assembly 230 is provided with a second connecting rod 231. A second return spring 232 is sleeved on the side of the second connecting rod 231. A glass slide pressing plate 233 is provided at the end of the second connecting rod 231 away from the connecting block 211. The glass slide pressing plate 233 is L-shaped and is located above the movable plate 221 and is in contact with the movable plate 221. The glass slide pressing plate 233 is slidably connected to the second connecting rod 231. A gap is provided between the glass slide pressing plate 233 and the movable cavity 222.

[0051] Understandably, the L-shaped design of the slide pressing plate 233, positioned above and in contact with the movable plate 221, effectively secures the slide to the movable plate 221. Once the slide is placed on the movable plate 221, the slide pressing plate 233, under the action of the second return spring 232, applies pressure to the slide, preventing it from moving or shaking during the staining process and ensuring the accuracy and consistency of the staining.

[0052] See Figures 5-7 As shown, limiting components are provided on both sides of the dyeing tank fixing plate 300. The limiting components are provided with limiters 320. The limiters 320 have through holes 330 and limiting cavities 322. The limiting cavities 322 are provided with second limiting blocks 323. The second limiting blocks 323 are fixed to the dyeing tank fixing plate 300. A second slide is provided between the limiting blocks and the dyeing tank fixing plate 300. The outer side of the limiters 320 is connected to the second slide. A third connecting rod 325 is provided on the side of the second limiting block 323 near the first slide 310. A third return spring 324 is sleeved on the side of the third connecting rod 325. The third connecting rod 325 corresponds to the position of the through hole 330.

[0053] Specifically, the limiter 320 is provided with a positioning hole 321 on the side near the dyeing tank assembly fixing plate 300, and a positioning rod 340 is provided on the dyeing tank assembly fixing plate 300 in the direction corresponding to the positioning hole 321. A connector 350 is sleeved on the side of the positioning plate, and the connector 350 is slidably connected to the positioning rod 340. The connector 350 is fixedly connected to the dyeing tank assembly fixing plate 300, and a push rod 360 is provided at the end of the positioning rod 340 away from the limiter 320.

[0054] As can be seen from the above, the limiter 320 is used to fix the dyeing tank assembly. Since the outer side of the limiter 320 is connected to the second slide rail, the limiter 320 can slide along the second slide rail on the dyeing tank assembly fixing plate 300. In the initial state, the third return spring 324 is in the natural state, the second limit block 323 is in the limit cavity 322, and the third connecting rod 325 does not pass through the through hole 330. When the dyeing tank assembly is placed, the limiter 320 slides backward relative to the second slide rail, the third connecting rod 325 passes through the through hole 330, the third return spring 324 on the side of the third connecting rod 325 is in a compressed state, applying an outward pushing force. The positioning hole 321 corresponds to the positioning rod 340 as the limiter 320 moves, pushing the positioning rod 340 through the positioning hole 321, fixing the limiter 320. After the dyeing tank assembly is placed, the positioning rod 340 is pulled out, and the limiter 320 resets under the action of the pushing force generated by the third spring.

[0055] See Figure 8 As shown, the support plate 410 includes an upper support plate 411, a middle support plate 412, and a lower support plate 413. The middle support plate 412 is inclined. There is a height difference between the upper support plate 411 and the lower support plate 413. A support column 420 is connected to the lower surface of the upper support plate 411. The upper support plate 411 and the middle support plate 412 are hinged together. The lower support plate 413 and the middle support plate 412 are hinged together. A baffle 430 is provided on the side of the lower support plate 413 except for the surface connected to the middle support plate 412. A push plate 460 is slidably connected to the lower surface of the lower support plate 413. A hydraulic mechanism 440 is provided below the push plate 460. The hydraulic mechanism 440 is fixedly connected to the bottom of the receiving chamber 110. A hydraulic rod 450 is provided at the output end of the hydraulic mechanism 440. The upper end of the hydraulic rod 450 is fixedly connected to the lower surface of the push plate 460.

[0056] Understandably, since the push plate 460 is slidably connected to the lower surface of the lower support plate 413, the upward movement of the push plate 460 will cause the lower support plate 413 to rotate upward around the hinge point with the middle support plate 412. Simultaneously, the upper support plate 411 rotates around the hinge point with the middle support plate 412, causing a change in the angle of the entire support plate 410 structure. By controlling the extension of the hydraulic rod 450, the tilt angle of the middle support plate 412 can be precisely adjusted, thereby changing the degree of tilt of the dyeing tank assembly.

[0057] See Figure 9 As shown, a mesh cover 120 is provided on the top of the box 100, and the mesh cover 120 is hinged to the box 100.

[0058] Specifically, a drain hole 130 is provided on the outer side of the housing 100, and the drain hole 130 is sealed by a sealing plug 140.

[0059] Specifically, the surfaces that come into contact with the glass slide are provided with an elastic buffer layer.

[0060] Understandably, during the cleaning stage after staining or in other situations requiring liquid drainage, the sealing plug 140 of the drain hole 130 can be opened to allow the waste liquid inside the chamber 100 to drain smoothly through the drain hole 130. This avoids the inconvenience and risk of liquid splashing that may occur when manually pouring out the liquid, and also facilitates centralized treatment of the waste liquid. During the placement and fixing of the slides, the elastic buffer layer can effectively reduce the impact and pressure on the slides, preventing them from breaking or being damaged due to collisions or compression. Especially for some thin or fragile slides, the elastic buffer layer can provide good protection and ensure the integrity of the slides. During operation, the elastic buffer layer can prevent the slides from directly contacting hard surfaces, thereby reducing the possibility of scratches on the slide surface, ensuring the surface quality of the slides, and facilitating subsequent observation and analysis of the slides.

[0061] Compared with the prior art, the beneficial effects of this utility model are as follows: The housing 100 is equipped with a receiving chamber 110, providing a relatively enclosed and orderly space for the overall staining operation. The staining support frame 400 is placed inside the receiving chamber 110 and connected to the support plate 410 via support columns 420, forming a stable support structure. This layout allows the staining tank assembly fixing plate 300 to slide on the support plate 410, facilitating flexible adjustment of the staining tank assembly position according to actual needs and achieving efficient space utilization. Simultaneously, the staining tank assembly consists of several retractable staining tanks 200 arranged together, allowing for flexible adjustment of the number and size of the staining tanks according to the number of slides and experimental requirements, greatly improving the adaptability of the staining rack to different experimental scales. The design of the retractable staining tanks 200 helps optimize the staining process. During staining, the staining tank can be adjusted to a suitable size according to the length and shape of the slide, ensuring that the staining solution can evenly cover the slide, avoiding waste of staining solution or uneven staining due to the staining tank being too large or too small, thereby improving the accuracy of experimental results. Meanwhile, the relatively enclosed environment of the containment chamber 110 can reduce the interference of external factors on the dyeing process, such as dust and airflow, and further ensure the stability of dyeing quality.
