TECHNICAL FIELD

[0001] The present application relates to a slide rack for loading slides in a microscopic scanning system. BACKGROUND

[0002] Generally, when a large number of slides are microscopically imaged and formed into digital slides, a multi-flux slide scanning instrument such as a digital slide scanner is needed, and such a scanning instrument generally needs a slide rack to support the slides, the slide rack clamps, fixes and stabilizes the slides in a relatively fixed position, the scanning instrument drives the slide rack to move in a horizontal plane, and then the scanning instrument's microscopic imaging part images and collects the images of the slides. Based on the above use requirements, whether the structure of the slide rack is simple, whether the clamping of the slide rack is firm, and whether the installation of the slide is convenient are all directions that need to be considered for improvement of the slide rack.

[0003] There are mainly two types of existing slide racks:

[0009] In an embodiment: the second X direction side of each slide groove is provided with an X direction positioning surface for positioning the slide in the X direction.

[0010] In one embodiment, one of the clamping jaws of each slice slot has a larger deformation stroke than the other clamping jaw, and the clamping jaw with the larger deformation stroke is located on the first Y-direction side of the slice slot.

[0012] In one embodiment, the slice holder body extends towards the inside of each slice slot and is provided with a lower supporting plate for supporting the slice, and the top surfaces of the two clamping jaws of each slice slot are respectively integrally provided with a first cover plate and a second cover plate for covering the slice, and the lower surfaces of the first cover plate and the second cover plate are located on the same horizontal plane, and the lower supporting plate and the first cover plate and the second cover plate form a space for accommodating the slice.

[0013] In one embodiment, the slice holder body is integrally provided with a third cover plate for covering the slice inside each slice slot, and the lower surface of the third cover plate is located on the same horizontal plane as the lower surfaces of the first cover plate and the second cover plate.

[0029] Please refer to Figure 1 and Figure 2The utility model provides a slice rack for the loading of slices 100 in a slice scanning instrument, which comprises a slice rack body 10, a plurality of slice grooves 11 are arranged on the slice rack body 10, the slice groove 11 is generally a rectangular groove, a horizontal rectangular coordinate system formed by the X direction and the Y direction is arranged, the two opposite sides of the X direction are arranged as the first X direction side and the second X direction side, the two opposite sides of the Y direction are arranged as the first Y direction side and the second Y direction side, a clamping jaw 12 and 13 are arranged on the first Y direction side and the second Y direction side in each slice groove 11 respectively, one end of the clamping jaw 12 and 13 is a connecting end connected (which can be fixedly connected) with the slice rack body 10, the connecting end of the two clamping jaws 12 and 13 in each slice groove 11 is located at the first X direction side of the X direction in the slice groove 11, the other end of the clamping jaw 12 and 13 is a free end and faces the second X direction side of the slice groove 11, and the clamping jaw 12 and 13 can produce bending deformation around the connecting end. When loading the slice, the slice 100 can be loaded into the slice groove 11, and meanwhile, the two ends of the slice 100 in the Y direction respectively push the two clamping jaws 12 and 13, so that the two clamping jaws 12 and 13 respectively produce elastic deformation in the direction away from each other around the respective connecting end, at this time, one clamping jaw (the clamping jaw on the first Y direction side) 12 has a force F1 on the slice 100, which can be decomposed into a force towards the second X direction side and a force towards the second Y direction side, and the other clamping jaw (the clamping jaw on the first Y direction side) 13 has a force F2 on the slice 100, which can be decomposed into a force towards the second X direction side and a force towards the first Y direction side, under the action of the resultant force of the elastic deformation of the two clamping jaws 12 and 13, the slice 100 is tightly clamped between the two clamping jaws 12 and 13 in the slice groove 11 and has a tendency to be pushed to and abut against the side wall of the second X direction side of the slice groove 11, the installation steps of the slice are less, and the installation is simple.

[0030] Please refer to Figure 3 Under the action of the resultant force F of the elastic deformation of the two clamping jaws 12 and 13, the resultant force F can be decomposed into a component force Fx towards the second X direction side, and the slice 10 has a tendency to be pushed to and abut against the side wall of the second X direction side of the slice groove 11, therefore, an X direction positioning surface for X direction positioning of the slice 100 is arranged on the second X direction side of each slice groove 11, so that the slice 100 is positioned in the X direction. One clamping jaw 12 on each slice groove 11 is arranged to have a greater deformation stroke than the other clamping jaw 13, and the clamping jaw with the greater deformation stroke is arranged on the first Y direction side of the slice groove 11, then according to the resultant force F of the two clamping jaws 12 and 13 on the slice 100, the resultant force F can be decomposed into a component force Fy towards the second Y direction side, and the slice 100 has a tendency to be pushed to and abut against the side wall of the second Y direction side of the slice groove 11, therefore, a Y direction positioning surface for Y direction positioning of the slice 100 is arranged on the second Y direction side of each slice groove 11, so that the slice 100 is positioned in the Y direction. After the slice 100 is loaded into the slice groove 11, a more stable installation state can be obtained by arranging the positioning surfaces in the X direction and the Y direction.

[0032] In the embodiment, two protrusions 111 are protruded along the Y direction on the second X-side wall of the slice slot 11, and the X-direction positioning surface is the top surface of the two protrusions 111. The second Y-side of the slice slot 11 is provided with a positioning wall 112 protruded from the slice holder body 10, and the Y-direction positioning surface is the wall surface of the positioning wall 112 facing the first Y-side.
