Abstract
Description
Technical Field
[0001] This utility model relates to the field of staining rack technology, specifically a staining rack for medical testing. Background Technology
[0002] A staining rack is a tool used to support and fix samples (such as glass slides), allowing the samples to remain stable during staining and facilitating various processing steps. Staining racks are typically designed for ease of cleaning, chemical resistance, and compatibility with different laboratory equipment (such as hot plates, staining machines, etc.). They are widely used in fields such as biology, medical testing, and pathology.
[0003] Based on the above, the inventors have discovered the following problems: the current main method of fixing the staining rack is to insert the slides longitudinally into the staining rack for fixation. This method of fixing has the problem of making it difficult to remove the slides when there are a large number of slides. When trying to remove one slide, it is easy to touch the adjacent slides. The edges of the slides are relatively fragile, and touching them may cause them to break or scratch, making them inconvenient to use.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a staining rack for medical testing, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a staining rack for medical testing to solve the problems mentioned in the background art.
[0006] A staining rack for medical testing includes a staining rack assembly. The staining rack assembly includes two support strips, with a plurality of positioning protrusions fixedly installed on the top of each support strip. The positioning protrusions are arranged at equal intervals. A plurality of guide rods are provided on both sides of the two support strips. A removal component is sleeved on the outer side of each guide rod. The guide rods are alternately arranged on both sides of the two support strips, and the guide rods are positioned on both sides between the positioning protrusions. The removal component includes a sliding block with a guide hole in the middle. The guide hole is sleeved on the outer side of the guide rod and is slidably connected to the guide rod. A groove is provided at the bottom end of the sliding block facing the support strip.
[0007] By adopting the above technical solution, the support strip facilitates the support of the bottom of the slide during use, thus fixing the slide. The positioning protrusions facilitate the formation of positioning grooves between them, achieving the function of positioning and fixing the bottom of the slide. The guide rods facilitate the sliding of the slider. The positions of the guide rods and positioning protrusions allow the guide rods to be alternately placed on both sides of the positioning grooves formed by the positioning protrusions, so that each guide rod corresponds to one positioning groove. Moreover, the greater distance between the guide rods and adjacent guide rods facilitates the up-and-down sliding of the slider. The guide hole facilitates the guidance and limitation of the slider's movement, ensuring that the slider can only slide up and down along the guide rods. The support groove facilitates the lifting of one corner of the slide located inside the positioning groove, so that pushing the slider upwards can lift the slide, making it easy to remove the slide and effectively avoiding contact with adjacent slides during the removal process.
[0008] Furthermore, an anti-slip groove is provided on the other side of the sliding block, and the cross-sections of the guide hole and the guide rod are both elliptical.
[0009] By adopting the above technical solution, the anti-slip groove facilitates a more stable up-and-down sliding of the sliding block. The guide holes and guide rods, all with elliptical cross-sections, help prevent rotation when the sliding block slides up and down.
[0010] Furthermore, side plates are fixedly installed at both ends of the support strip, and a bottom strip is fixedly installed at the bottom between the two side plates.
[0011] By adopting the above technical solution, the side plates and bottom strips facilitate the formation of a stable frame structure for the dyeing rack assembly.
[0012] Furthermore, a top strip is fixedly installed at the top between the two side plates, and a side strip is fixedly installed in the middle between the two side plates.
[0013] By adopting the above technical solution, the side strips and top strips facilitate the installation of the positioning strips and provide an installation foundation.
[0014] Furthermore, the bottom of the side strip is fixedly connected to the top of the guide rod, and the top of the bottom strip is fixedly connected to the bottom of the guide rod.
[0015] By adopting the above technical solution, the side strips and bottom strips facilitate the fixed installation of the guide rod.
[0016] Furthermore, a positioning strip is fixedly installed on one side of the top strip and the side strip, and the position of the positioning strip corresponds to the position of the positioning protrusion.
[0017] By adopting the above technical solution, the positioning strips facilitate the formation of positioning grooves between them, which makes it easier to guide and position the slide when it is placed in the slide, and also allows the slide to be fixed during staining.
[0018] Furthermore, a central plate is fixedly installed at the top center of the support strip, and the two sides of the central plate are fixedly connected to the top strip and the side strip.
[0019] By adopting the above technical solution, the middle plate is fixedly connected to the top strip and side strip on both sides, which facilitates the fixed installation of the middle plate in the middle of the dyeing rack assembly.
[0020] Furthermore, the top of the middle plate extends to the outer side of the top strip, and handle grooves are provided on both sides of the top of the top strip.
[0021] By adopting the above technical solution, the top of the middle plate extends to the outer side of the top strip, and handle grooves are provided on both sides of the top of the top strip, so that the handle grooves can be set in the middle of the top of the dyeing rack assembly, making it convenient and stable to lift the device for movement.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The support strip facilitates the support of the bottom of the slide during use, thus fixing the slide; the positioning protrusions facilitate the formation of positioning grooves between them, achieving the function of positioning and fixing the bottom of the slide; the guide rods facilitate the guidance of the sliding block's movement; and the positioning positions of the guide rods and positioning protrusions allow the guide rods to be alternately positioned on both sides of the positioning grooves formed by the positioning protrusions, ensuring that each guide rod corresponds to one positioning groove, and that the guide rods are aligned with adjacent guide rods. The greater distance between the guide rods facilitates the sliding of the slider up and down. The guide hole facilitates the guidance and limitation of the slider's movement, ensuring that the slider can only slide up and down along the guide rod. The slot design facilitates the lifting of a corner of the slide located inside the positioning slot, allowing the slide to rise when the slider is pushed upwards, making it easy to remove the slide and effectively preventing contact with adjacent slides during removal. This utility model can accurately and stably remove specific slides while effectively avoiding contact with adjacent slides, and has high practical value. Attached Figure Description
