[0022] Figure 1 FIG. 4 is an overall schematic diagram of the measuring device 100 provided for this application. Figure 2 FIG. 5 is a sectional schematic diagram of the measuring device 100 provided for this application. Refer to Figure 1 and Figure 2, the measuring device 100 is used to measure the lateral tilt angle of a glass slide. The measuring device 100 includes an upper housing 1, a lower housing 2, a bead screw 3, a slide pressing plate 4, a slide fixing plate 5, a first compression spring 6, a pressing block 7, a rotating shaft 8, and a rotating pointer 9. A through hole is provided on the left side of the lower housing 2, and a thread for cooperating with the bead screw 3 is provided on the through hole. The bead screw 3 is threadedly connected to the lower housing 2 through the through hole. The slide pressing plate 4 is attached to the bead screw 3 and installed inside the lower housing 2. The slide fixing plate 5 is fixed inside the lower housing 2 and is disposed opposite to the slide pressing plate 4. An inclined surface area is provided on the side of the slide pressing plate 4 close to the slide fixing plate 5. Inside the lower housing 2, the first compression spring 6 is fixedly installed on the lower side of the lower housing 2. The pressing block 7 is installed above the first compression spring 6. The inclined surface area of the pressing block 7 is disposed opposite to and matches the inclined surface area of the slide pressing plate 4. A protrusion is provided on one side of the pressing block 7, and the protrusion extends outside the lower housing 2. The rotating shaft 8 is fixed inside the upper housing 1, and the rotating pointer 9 can rotate around the rotating shaft 8. The tip of the rotating pointer 9 faces the right end surface of the upper housing 1. Corresponding scale lines are provided on the right end surface of the upper housing 1. The space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9 is used to hold the glass slide.

[0023] Specifically, in the measuring device 100 provided in this application, the number of bead screws 3 can be determined according to the actual scenario. Specifically, it can be 2, 3, 4, etc., to ensure that the slide pressing plate 4 can be evenly stressed around the bead screw 3, so that the slide pressing plate 4 can smoothly move to the left side of the lower housing. In addition, the protrusion in this application can be provided on the right side, front side, or rear side of the pressing block 7. Under the action of force, the pressing block 7 presses down the first compression spring 6. The pressing block 7 moves downward under the elastic force of the first compression spring 6. The inclined surface area of the pressing block 7 slides downward to squeeze the inclined surface area of the slide pressing plate 4, so that the slide pressing plate 4 can slide to the left side of the lower housing 2 under the elastic force of the bead screw 3, and the distance between the slide pressing plate 4 and the slide fixing plate 5 increases; the space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9 increases. When the space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9 is large enough to accommodate the glass slide, the glass slide can be inserted into the space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9. After the glass slide is inserted into the space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9, the action of force ends. Under the reaction force of the first compression spring 6, the pressing block 7 can push the glass slide to stably bind the glass slide in the space formed by the lower end surfaces of the slide fixing plate 5, the slide pressing plate 4, and the rotating pointer 9.

[0024] It can be understood that when inserting the glass slide into the space formed by the lower end faces of the glass slide fixing plate 5, the glass slide pressing plate 4, and the rotating pointer 9, it is necessary to make the side of the glass slide to be measured closely adhere to the lower end face of the rotating pointer 9 so as to measure the inclination angle of the side of the glass slide. When the side of the glass slide is inclined, the glass slide provides a certain thrust to the rotating pointer 9. Under the thrust of the glass slide, the rotating pointer 9 will deflect by a certain angle. If the inclination angles of the sides of the glass slides are different, the deflection angles of the rotating pointer 9 will be different, that is, the positions of the tip of the rotating pointer 9 on the scale line on the right end face of the upper housing 1 are different. At this time, based on the value pointed by the tip of the rotating pointer 9, the inclination angle of the side of the glass slide can be determined.

[0025] Figure 3 and Figure 4 is a schematic diagram of the working principle of the rotating pointer 9 in the measuring device 100 provided by this application. As Figure 2 shown, when the side of the glass slide is not inclined, that is, the included angle between the side of the glass slide and the surface of the glass slide 7 is 90 degrees, the rotating pointer 9 does not rotate, and the position of the tip of the rotating pointer 9 on the scale line on the right end face of the upper housing 1 remains unchanged. As Figure 3 shown, when the side of the glass slide is inclined by 70 degrees, that is, the included angle between the side of the glass slide and the surface of the glass slide is 70 degrees, the rotating pointer 9 rotates by a certain angle, and the position of the tip of the rotating pointer 9 on the scale line on the right end face of the upper housing 1 changes. Then, based on the value pointed by the tip of the rotating pointer 9, the inclination angle of the side of the glass slide can be determined.

[0026] Continue to refer to Figure 2 , in one embodiment, the measuring device 100 further includes a second compression spring 10; inside the upper housing 1, one end of the second compression spring 10 is fixedly installed on the upper side of the upper housing 1, and the other end of the second compression spring 10 abuts against the rotating pointer 9.

[0027] Specifically, by providing the second compression spring 10 in the measuring device 100, after the measuring device 10 finishes measuring the side of the glass slide once, under the elastic force of the second compression spring 10, the rotation angle of the rotating pointer 9 can be restored to the initial state.

[0028] Continue to refer to Figure 2 , in one embodiment, the measuring device 100 further includes a glass sheet 11, and the glass sheet 11 is fixed to the lower end face of the rotating pointer 9.

[0029] Specifically, by providing the glass sheet 11 on the lower end face of the rotating pointer 9, the rotating pointer 9 will not be deformed under the extrusion of the glass slide, avoiding the influence of the extrusion of the glass slide on the measurement result.

[0030] Continue to refer to Figure 1, in one embodiment, the measuring device 100 further includes a handle 12 fixedly installed below the lower housing 2.

[0031] Specifically, by providing the handle 12 below the lower housing 2, it is convenient to grip the measuring device 100, making the measuring device 100 more convenient to use.

[0032] In the prior art, a microscope generally fixes the side of a glass slide. If the side of the glass slide is inclined, then after the glass slide is fixed, the glass slide is also inclined, which results in a blurred field of view on one side and a clear field of view on the other side when the full-automatic microscope scans the glass slide flat, and the imaging effect of cell tissues is poor. Therefore, whether the side of the glass slide is inclined is crucial for the scanning of the full-automatic microscope.

[0033] To solve the above problems, the present application provides a measuring device for measuring the inclination angle of the side of a glass slide, characterized in that the measuring device includes an upper housing, a lower housing, a bead screw, a glass slide pressing plate, a glass slide fixing plate, a first compression spring, a pressing block, a rotating shaft, and a rotating pointer; a through hole is provided on the left side of the lower housing, and a thread for cooperating with the bead screw is provided on the through hole, and the bead screw is threadedly connected to the lower housing through the through hole, and the glass slide pressing plate is attached to the bead screw and installed in the lower housing; the glass slide fixing plate is fixed in the lower housing and is arranged opposite to the glass slide pressing plate; a bevel region is provided on the side of the glass slide pressing plate close to the glass slide fixing plate; in the lower housing, the first compression spring is fixedly installed on the lower side of the lower housing; the pressing block is installed above the first compression spring, and the bevel region of the pressing block is arranged opposite to and matches the bevel region of the glass slide pressing plate; a protrusion is provided on one side of the pressing block, and the protrusion extends outside the lower housing; the rotating shaft is fixed in the upper housing, and the rotating pointer can rotate around the rotating shaft; the tip of the rotating pointer is opposite to the right end face of the upper housing; corresponding scale lines are provided on the right end face of the upper housing; the space formed by the lower end faces of the glass slide fixing plate, the glass slide pressing plate, and the rotating pointer is used to carry the glass slide. By providing a pressing block and a glass slide pressing plate that matches the bevel region of the pressing block in the measuring device, the present application can adjust the space for accommodating the glass slide and fix the glass slide to be measured, so that the measuring device can be applicable to glass slides of different thicknesses. In addition, by providing a rotating pointer in the measuring device, the present application enables the inclination angle of the side of the glass slide to be feedback based on the rotation angle of the rotating pointer, making the measurement of the inclination angle of the side of the glass slide more intuitive, convenient, and efficient.
