Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide staining, and in particular to a pathological slide staining rack. Background Technology
[0002] Pathological slide staining racks are commonly used equipment in pathology laboratories. They are mainly used to support slides for tissue staining. By placing the slides into the slide staining rack, the slides to be stained can be immersed in the staining agent to stain the specimens on the slides.
[0003] A patent application filed on November 23, 2019, with application number CN201922040141.7, discloses a slide staining rack for a laboratory, comprising: a slide rack placed inside a staining tank; a tank lid fitted on top of the tank; the diameter of the tank's bottom being smaller than the diameter of its top; and side support plates on both sides, with strip-shaped stops inserted at the front and rear of the top of each side support plate; supports fixedly connected to the middle and lower parts of each side support plate; and I-shaped stops inserted within the supports. Clamping clips one and two are fixedly connected to the I-shaped stops and strip-shaped stops near the inner ends of the slide rack, respectively. Its structure is simple, the staining tank has strong sealing, the slides are not easily loosened, it is detachable and reassembleable, and easy to clean.
[0004] However, after the staining rack is removed after staining, the staining agent adhering to the surface of the slide and the surface of the staining rack will drip down, which will contaminate the experimental table and other places. In addition, the spacing between adjacent slides is small, which will interfere with the adjacent slides when removing one slide, making it inconvenient to remove the corresponding slides individually. Therefore, further improvements can be made. Summary of the Invention
[0005] In order to solve the problems existing in the background art, this utility model proposes a pathological slide staining rack.
[0006] A pathological slide staining rack includes a frame with legs at the bottom. Several partitions are fixedly installed on the inner walls of the two long sides of the frame, and a receiving groove for placing slides is provided between each pair of adjacent partitions. A bottom rod is fixedly installed at the middle of the bottom end of the frame, and a groove is formed in the bottom rod corresponding to the receiving groove. A lifting plate is fixedly installed in the middle of the frame. Retractable support members are provided in the top of the two long sides of the frame. Several fixing plates are fixedly installed at the bottom of the frame and on both sides of the bottom rod, and a slide picking assembly is provided inside the fixing plates.
[0007] Based on the above, the top of the lifting plate has a protrusion, and the center of both sides of the protrusion has a recess.
[0008] Based on the above, the retractable support includes a telescopic rod that is slidably inserted into the top of the long side of the frame, and a handle is fixedly installed at the end of the telescopic rod.
[0009] Based on the above, the retrieval assembly includes a push rod that is slidably inserted into the inside of a fixed plate. An active chamber is formed in the middle of the fixed plate. A wedge is fixedly installed at one end of the push rod that enters the active chamber. A return spring is fixedly installed between the wedge and the side wall of the active chamber. A clamping block is slidably connected to the middle of the active chamber. A top rod is fixedly installed at the top of the clamping block, and the top rod is inserted through the middle of the recess of the bottom rod.
[0010] Based on the above, the wedge is in the shape of a right trapezoid, the bottom of the clamping block is triangular, and the inclined side of the wedge and the inclined side of the clamping block abut against each other.
[0011] Based on the above, a roller is rotatably connected to the top of the wedge near the clamping block, and the roller rolls against the inclined side of the clamping block.
[0012] This invention has substantial features and advancements compared to existing technologies. Specifically, by pulling out and unfolding the retractable support, the staining rack can be placed on top of the staining tank, suspending it in the air. This allows the staining agent on the staining rack and the surface of the slides to be drained. Simultaneously, by pressing the push rods on both sides, the wedge blocks are driven to squeeze the bottom of the clamping blocks, which in turn pushes the top rod upwards out of the concave bottom wall, thereby lifting the slides located in the concave area upwards, making it convenient to remove the corresponding slides individually. This invention has the advantages of conveniently controlling the drying of staining agent and conveniently removing slides individually. Attached Figure Description

[0018] 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.
[0019] like Figures 1-4 As shown, a pathological slide staining rack includes a frame 1, with legs 2 at the bottom of the frame 1. Several partitions 3 are fixedly installed on the inner walls of the two long sides of the frame 1. Each pair of adjacent partitions 3 has a receiving groove 4 for placing slides. A bottom rod 5 is fixedly installed in the middle of the bottom end of the frame 1, and a groove is opened in the bottom rod 5 corresponding to the receiving groove 4. A lifting plate 6 is fixedly installed in the middle of the frame 1. Retractable support members are provided in the top of the two long sides of the frame 1. Several fixing plates 8 are fixedly installed at the bottom of the frame 1 and on both sides of the bottom rod 5. A slide picking assembly 9 is provided inside the fixing plate 8.
[0020] When in use, the top of the lifting plate 6 has a protrusion, and the center of both sides of the protrusion has a recess. By pinching the recesses on both sides, it is easy to lift the dyeing rack into and out of the dyeing tank. After dyeing, the telescopic support includes a telescopic rod 7 that is slidably inserted into the top of the long side of the frame 1. The end of the telescopic rod 7 is fixedly installed with a handle. By pulling the handle, the telescopic rod 7 can be pulled outward to extend the side of the dyeing rack. Therefore, by lifting the dyeing rack and placing the telescopic rod 7 on the top of the dyeing tank, the dyeing rack can be suspended and placed still, which facilitates the dye on its surface to drip down and drain.
[0021] In reality, the retractable support can also be a rotating plate that is rotatably connected to the side of the staining rack. The rotating plate fits against the short side of the staining rack and restricts rotation by 90 degrees. By flipping the rotating plate 90 degrees, it can be unfolded and kept horizontal with the top of the staining rack, which makes it easy to place it on top of the staining tank to suspend the staining rack, thereby allowing the staining agent on the staining rack and the surface of the slide to drain.
[0022] Specifically, the slide retrieval assembly 9 includes a push rod 10 that is slidably inserted into the fixed plate 8. An active chamber 11 is provided in the middle of the fixed plate 8. A wedge block 12 is fixedly installed at one end of the push rod 10 that enters the active chamber 11. A reset spring 13 is fixedly installed between the wedge block 12 and the side wall of the active chamber 11. A clamping block 14 is slidably connected to the middle of the active chamber 11. A top rod 15 is fixedly installed at the top of the clamping block 14. The top rod 15 is inserted through the middle of the recess of the bottom rod 5. By pressing the push rods 10 on both sides, the wedge block 12 will squeeze the bottom of the clamping block 14, which will push the top rod 15 upward and protrude from the bottom wall of the recess, thereby lifting the glass slide located in the recess upward, making it convenient to remove the corresponding glass slide individually. The reset spring 13 can drive the wedge blocks 12 on both sides to reset after the push rod 10 is released after the glass slide is removed.
[0023] In reality, the wedge 12 is in the shape of a right trapezoid, the bottom of the clamping block 14 is in the shape of a triangle, and one side of the inclined surface of the wedge 12 and one side of the inclined surface of the clamping block 14 are in contact. By pressing the push rod 10, one side of the inclined surface of the wedge 12 will be pushed closer to the side of the inclined surface of the clamping block 14, which will then squeeze and drive the push rod 15 to move upward.
[0024] In reality, a roller 16 is rotatably connected to the top of the wedge 12 near the clamping block 14, and the roller 16 rolls against the inclined side of the clamping block 14. As the wedge 12 gets closer, it will cause the roller 16 to press against the inclined side of the clamping block 14, so that the roller 16 rolls along the inclined side of the clamping block 14, thereby reducing friction and making it easier to press the clamping block 14 to drive the push rod 15 to bulge upward and push out the glass slide.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
