Description

Technical Field

[0001] This utility model relates to the field of inspection technology, and in particular to a smear applicator for inspection. Background Technology

[0002] When preparing glass slides, a smear applicator is used to evenly spread the sample onto the slide. Smear cotton is used during this process, and its movement ensures even distribution of the sample. Slides are generally available in three sizes: 75mm × 25mm slides, also known as standard slides, are the most commonly used; 26mm × 76mm slides, also known as long slides, are typically used in histological research and clinical medicine; and 50mm × 75mm slides, also known as immunohistochemical slides, are commonly used in immunohistochemistry. However, because the length of the smear cotton is generally fixed, existing smear applicators can only spread slides of fixed sizes, thus limiting their use. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing applicators, which limit their use by only being able to apply to slides of fixed sizes, and to propose an applicator for testing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a smear applicator for testing, including a base plate, a movable plate connected to the base plate via a moving mechanism, a glass slide connected to the movable plate via a fixing mechanism, two side plates on the base plate, a rotating shaft rotatably connected to the two side plates via bearings, multiple connecting rods fixedly connected to the rotating shaft, each connecting rod fixedly connected to a connecting plate, and smear cotton glued to each of the multiple connecting plates, the lengths of the multiple smear cotton being different, and the rotating shaft being positioned by a positioning mechanism.

[0006] Preferably, the moving mechanism includes a slide groove formed on the base plate, a slider is slidably disposed in the slide groove, a threaded rod is threadedly connected to the slider, the threaded rod is rotatably connected to the slide groove through a bearing, and the threaded rod is driven by a micro motor.

[0007] Preferably, a bolt is threaded through the side plate, and the bolt is threadedly connected to the base plate.

[0008] Preferably, the fixing mechanism includes two miniature telescopic rods, which are fixedly connected to the movable plate, and abutment blocks are fixedly connected to the opposite inner sides of the two miniature telescopic rods.

[0009] Preferably, the threaded rod is a reciprocating threaded rod.

[0010] Preferably, the positioning mechanism includes a limiting sleeve, which is fixedly connected to the side plate. Multiple positioning holes are evenly spaced around the circumference of the rotating shaft. A positioning rod is provided inside the limiting sleeve and extends into the positioning hole. A spring is fixedly connected to the positioning rod, and a connecting ear is fixedly connected to the spring. The connecting ear is fixedly connected to the side plate.

[0011] Preferably, a movable column is fixedly connected to the positioning rod.

[0012] The present invention proposes a smear applicator for testing, which has the following advantages: the length of the smear cotton of different lengths corresponds to the width of the glass slide. By rotating the shaft, multiple smear cotton are driven to rotate, so that the smear cotton matching the width of the glass slide comes into contact with the glass slide. When the glass slide moves back and forth, smearing is performed, so that glass slides of different sizes can be smeared, thus improving the adaptability of the device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3A smear applicator for testing includes a base plate 1, a movable plate 7 connected to the base plate 1 via a moving mechanism, a glass slide connected to the movable plate 7 via a fixing mechanism, two side plates 2 on the base plate 1, and a rotating shaft 10 rotatably connected to the two side plates 2 via bearings. Multiple connecting rods 8 are fixedly connected to the rotating shaft 10, and connecting plates 9 are fixedly connected to each of the multiple connecting rods 8. Smear cotton 3 is adhered to each of the multiple connecting plates 9. The lengths of the multiple smear cotton 3 are all different. The rotating shaft 10 is positioned by a positioning mechanism. The different lengths of the smear cotton 3 correspond to glass slides of different widths. By rotating the rotating shaft 10, the multiple smear cotton 3 are rotated, bringing the smear cotton 3 matching the width of the glass slide into contact with the glass slide. As the glass slide reciprocates, smearing is performed, allowing for smearing of glass slides of different sizes, thus improving the adaptability of the device.

[0019] The moving mechanism includes a slide 6, which is formed on the base plate 1. A slider is slidably disposed in the slide 6, and a threaded rod 5 is threadedly connected to the slider. The threaded rod 5 is a reciprocating threaded rod, which can drive the slider to move back and forth without the need for the micro motor 4 to rotate forward and backward. The threaded rod 5 is rotatably connected to the slide 6 through a bearing. The micro motor 4 is mounted on the base plate 1, and the threaded rod 5 is driven by the micro motor 4. When the micro motor 4 rotates, it drives the threaded rod 5 to rotate, thereby driving the slider to move in the slide 6, thereby driving the moving plate 7 to move back and forth, and driving the glass slide to move back and forth.

[0020] A bolt 16 is threaded through the side plate 2 and is threaded to the base plate 1 so that the side plate 2 can be removed to clean or replace the cotton pad 3.

[0021] Example 2: Refer to Figure 1-3 As another preferred embodiment of the present invention, based on embodiment 1, the fixing mechanism includes two miniature telescopic rods 12, which are fixedly connected to the moving plate 7. Each of the two miniature telescopic rods 12 has a stop block 11 fixedly connected to its opposite inner side. By extending the miniature telescopic rods 12, the stop blocks 11 are moved, thereby fixing the glass slide.

[0022] Example 3: Reference Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 2, the positioning mechanism includes a limiting sleeve 14, which is fixedly connected to the side plate 2. Multiple positioning holes 17 are evenly spaced around the rotating shaft 10. A positioning rod 13 is provided inside the limiting sleeve 14, extending into the positioning hole 17. A spring 15 is fixedly connected to the positioning rod 13, and a connecting ear is fixedly connected to the spring 15, which is also fixedly connected to the side plate 2. The number of positioning holes 17 is equal to the number of coating cotton 3. By placing the positioning rod 13 in the positioning hole 17, the rotating shaft 10 is limited, preventing the coating cotton 3 from rotating during application.

[0023] A movable column is fixedly connected to the positioning rod 13. The positioning rod 13 is moved by the movable column to disengage it from the positioning hole 17 and release the fixing of the rotating shaft 10.

[0024] In use, a glass slide of the same thickness is placed on the moving plate 7, and the micro telescopic rod 12 is extended to move the abutment block 11, which fixes the glass slide. According to the width of the glass slide, the rotating shaft 10 is rotated to drive multiple smear cotton 3 to rotate, so that the smear cotton 3 matching the width of the glass slide comes into contact with the glass slide. The positioning rod 13 is placed in the positioning hole 17, which will limit the rotation shaft 10. Then, the liquid sample is squeezed out along the width of the glass slide in a straight line equal to the width of the glass slide. The micro motor 4 is rotated, which drives the threaded rod 5 to rotate, thereby driving the slider to move in the slide groove 6, thereby driving the moving plate 7 to move back and forth, and driving the glass slide to move back and forth, so that the sample is evenly spread on the glass slide.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
