DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] In the present disclosure, unless otherwise stated, directional words such as "first direction, second direction, third direction" are used. Figure 1 and Figure 2 As shown. The terms used, such as "first" and "second", are only used to distinguish one element from another element, and do not have order or importance. In addition, the directional words used above are only used to simplify the description of the present disclosure, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and cannot be understood as a limitation of the present disclosure.

[0038] As a first aspect of the present disclosure, Figures 1 to 7As shown, the present disclosure provides a slice rack 100, including a slice rack body 1 and a lifting handle 2. The slice rack body 1 is formed with a plurality of slice slots 11 extending along a first direction X. The plurality of slice slots 11 are arranged at intervals along a second direction Y perpendicular to the first direction X. The slice slots 11 are used for inserting slices. A first connecting portion 21 is provided at the first end of the lifting handle 2, and a lifting portion 22 located outside the slice rack body 1 is provided at the second end of the lifting handle 2. A second connecting portion 12 and a third connecting portion 17 are provided on the slice rack body 1. The first connecting portion 21 can be selectively detachably connected to the second connecting portion 12 or the third connecting portion 17.

[0039] Among them, the slicer rack 100 has a first usage state and a second usage state. In the first usage state, the first connection part 21 is connected to the second connection part 12, and the lifting handle 2 extends along the first direction X; in the second usage state, the first connection part 21 is connected to the third connection part 17, and the lifting handle 2 extends along the second direction Y.

[0040] When using the slice rack 100 provided by the present invention, when the operator needs to load slices onto the slice rack 100, the first connection portion 21 of the lifting handle 2 can be connected to the second connection portion 12 of the slice rack body 1. At this time, the extension direction of the lifting handle 2 is parallel to the extension direction of the slice slot 11, that is, the lifting handle 2 and the slice slot 11 both extend along the first direction X. The operator can make the extension direction of the lifting handle 2 parallel to the direction of gravity, so that the operator can lift and move the position of the slice rack 100, and it is convenient for the operator to insert the slice rack 100 into the slice slot 11 along the vertical direction (that is, the direction of gravity). When the slice rack 100 loaded with slices needs to be placed in the staining box for staining, the first connection portion 21 of the lifting handle 2 can be connected to the third connection portion 17 of the slice rack body 1. At this time, the extension direction of the lifting handle 2 is perpendicular to the extension direction of the slice slot 11, that is, the lifting handle 2 extends along the second direction Y. The operator can make the extension direction of the lifting handle 2 parallel to the gravity direction so that the slice slot 11 extends in the horizontal direction to prevent the tissue on the slice from falling off under the action of gravity. Whether in the above-mentioned first use state or the second use state, the operator can make the lifting handle 2 parallel to the gravity direction to put down or lift the slice rack body 1 along the extension direction of the lifting handle 2.

[0041] Through the above technical solution, the first connection part 21 can be selectively connected with the second connection part 12 and the third connection part 17, so that the lifting handle 2 can be installed at different positions of the slice rack 100, that is, the slice rack 100 is switched between the first use state and the second use state, thereby changing the extension direction of the slice slot 11 in the slice rack 100, so that the extension direction of the slice can be the same as or perpendicular to the gravity direction when the slice rack 100 is lifted or lowered. When the extension direction of the slice is perpendicular to the gravity direction, the tissue on the slice can be supported by the slice, thereby avoiding the situation where the tissue on the slice falls off under the action of gravity when the staining liquid in the staining box reduces the friction between the tissue on the slice and the slice.

[0042] The present disclosure does not limit the connection method between the first connection part 21 and the second connection part 12 or the third connection part 17. In one embodiment provided in the present disclosure, the first connection part 21 and the second connection part 12 can be snap-fitted, and the first connection part 21 and the third connection part 17 can be snap-fitted. The snap-fitting is conducive to the installation and disassembly between the first connection part 21 and the second connection part 12 or the third connection part 17, and improves the speed and convenience of switching the first use state and the second use state of the slice rack 100.

[0043] In another embodiment provided by the present disclosure, the first connection part 21 includes a first magnetic member, the second connection part 12 includes a second magnetic member, and the third connection part 17 includes a third magnetic member. The first magnetic member and the second magnetic member can attract each other, and the first magnetic member and the third magnetic member can attract each other. The first connection part 21 is connected to the second connection part 12 or the third connection part 17 by magnetic connection, which facilitates the connection and disassembly of the first connection part 21 and the second connection part 12 or the third connection part 17, and is conducive to increasing the convenience of operation.

[0044] The present disclosure does not limit the specific type of the magnetic component. For example, it can be a neodymium iron boron magnet, a samarium cobalt magnet, or an aluminum nickel cobalt magnet.

[0045] Alternatively, if Figure 1 and Figure 2 As shown, the slice frame body 1 includes two first frames 13 arranged opposite to each other along a third direction Z, two second frames 14 arranged opposite to each other along a second direction Y, and a connecting plate 15, wherein the first direction X and the second direction Y are both perpendicular to the third direction Z. The two first frames 13 and the two second frames 14 together enclose a slice accommodating space 16, and the slice groove 11 is located in the accommodating space 16 and formed on the first frames 13. The connecting plate 15 extends along the first direction X, is located in the accommodating space 16 and is connected to the two first frames 13, and the second connecting portion 12 is arranged at one end of the connecting plate 15. A third connecting portion 17 is arranged on at least one of the two second frames 14.

[0046] The two second frames 14 are arranged relatively to each other along the second direction Y, and the plurality of slicing grooves 11 are arranged at intervals along the second direction Y, that is, the slices are arranged at intervals between the two second frames 14 along the second direction Y; the two first frames 13 are arranged relatively to each other along the third direction Z, and the third direction Z is perpendicular to the second direction Y. The slicing grooves 11 are formed on the first frames 13, and corresponding slicing grooves 11 are respectively formed on the two first frames 13, so as to clamp and fix the slices on both sides of the slices.

[0047] The connecting plate 15 extends along the first direction X and is connected to the two first frames 13, so that the connecting plate 15 can be located between the slices arranged at intervals. On the one hand, it can provide support force for the first frame 13, so that the accommodating space 16 is not easily deformed due to uneven force, thereby affecting the placement of the slices; on the other hand, the second connecting portion 12 is located at one end of the connecting plate 15, and the lifting handle 2 can be connected to the second connecting portion 12 on the connecting plate 15 through the first connecting portion 21, so that the slice rack body 1 is lifted or lowered through the connecting plate 15, which increases the stability of the slice rack 100 in the first use state.

[0048] In the second use state of the slice rack 100, the lifting handle 2 extends along the second direction Y, the two second rack bodies 14 are arranged opposite to each other along the second direction Y, and the slice is located between the two oppositely arranged second rack bodies 14. The third connecting portion 17 is arranged on the second rack body 14, and in the second use state of the slice rack 100, when the slice rack body 1 is lifted or lowered by the lifting handle 2, the gravity direction can be made to coincide with the second direction Y, so that the extension direction of the slice is perpendicular to the gravity direction, providing bearing force for the tissue on the slice.

[0049] Alternatively, if Figure 1 , Figure 2 and Figure 4 As shown, the first frame 13 also includes a limiting strip 131 and a plurality of limiting protrusions 132. The limiting strip 131 is located at one end of the connecting plate 15 away from the second connecting portion 12 and extends along the second direction Y. The two ends of the limiting strip 131 are respectively connected to the two second frames 14. The plurality of limiting protrusions 132 are arranged on the limiting strip 131 at intervals along the second direction Y, and the limiting groove formed between two adjacent limiting protrusions 132 is arranged corresponding to the slicing groove 11 on the first frame 13.

[0050] There are two limit bars 131 , and the two limit bars 131 are arranged at intervals along the third direction Z. The limit grooves on the two limit bars 131 are arranged in a one-to-one correspondence with the slicing grooves 11 on the two first frames 13 .

[0051] When the slice rack 100 is in the first use state, the lifting handle 2 extends along the first direction X, the slice in the slice slot 11 extends along the first direction X, the gravity direction is the same as the first direction X, the first rack body 13 can limit the displacement of the slice along the third direction Z, the slice slot 11 can limit the displacement of the slice along the second direction Y, and the limiting bar 131 can support the slice along the first direction X, so that the slice is always located in the accommodating space 16 during the lifting process. The limiting groove formed by the limiting protrusion 132 is arranged corresponding to the slice slot 11, which can respectively limit the position of the two ends of the slice along the first direction X, reducing the possibility of shaking of the slice during movement.

[0052] Alternatively, if Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the lifting handle 2 includes two elastic arms 23 arranged opposite to each other, the first connecting portion 21 includes two clamping portions 211, the first end of each elastic arm 23 is provided with a clamping portion 211, the clamping portion 211 on one of the two elastic arms 23 is located on the side of the elastic arm 23 away from the other elastic arm 23, and the second end of each elastic arm 23 is connected to the lifting portion 22. An insertion hole 151 is formed at one end of the connecting plate 15, and the second connecting portion 12 includes two first clamping holes 121 formed on the connecting plate 15, the two first clamping holes 121 are arranged opposite to each other along the third direction Z and are both connected to the insertion hole 151, and the two clamping portions 211 can extend into the insertion hole 151 and be clamped into the two first clamping holes 121 respectively. At least one of the two second frames 14 is formed with a long hole 141, the third connecting portion 17 includes two second clamping holes 171 formed on the second frame 14, the two second clamping holes 171 are arranged opposite to each other and are both connected to the long hole 141, and the two clamping portions 211 extend into the long hole 141 and are respectively clamped in the two second clamping holes 171.

[0053] In order to allow the clamping portion 211 to be retained in the first clamping hole 121 or the second clamping hole 171, the spacing between the elastic arms 23 disposed oppositely may be greater than or equal to the spacing between the first clamping hole 121 or the second clamping hole 171 disposed oppositely, so that when the clamping portion 211 extends into the insertion hole 151 or the long hole 141, the elastic arms 23 may be deformed and approach each other under the action of the hole wall of the insertion hole 151 or the long hole 141, so that the clamping portion 211 enters the insertion hole 151 or the long hole 141. Thereafter, due to the spacing between the elastic arms 23 and the elastic action, the clamping portion 211 enters the first clamping hole 121 or the second clamping hole 171 under the action of the elastic arms 23, and the clamping is completed.

[0054] When releasing the engagement between the engaging portion 211 and the first engaging hole 121 or the second engaging hole 171, the operator can exert a force on the elastic arm 23 to bring the two elastic arms 23 closer to each other, thereby allowing the engaging portion 211 to withdraw from the first engaging hole 121 or the second engaging hole 171, thereby releasing the connection between the lifting handle 2 and the slice rack body 1.

[0055] To facilitate the installation of the lifting handle 2, optionally, as Figure 3 As shown, the surface of the clamping portion 211 away from the elastic arm 23 is formed as an inclined surface 2111, and the inclined surface 2111 is used to abut against the hole wall of the insertion hole 151 or the hole wall of the long hole 141, so that the two elastic arms 23 can approach each other. In the process of the elastic arm 23 extending into the insertion hole 151 or the long hole 141, the surface of the clamping portion 211 on the side away from the elastic arm 23 has a tendency to move toward the first clamping hole 121 or the second clamping hole 171 under the elastic force of the elastic arm 23. By setting the surface as the inclined surface 2111, the downward thrust on the elastic arm 23 can be converted into a thrust for squeezing the two elastic arms 23 closer to each other during the process of the elastic arm 23 extending into the insertion hole 151 or the long hole 141, thereby reducing the operation of the operator squeezing the elastic arm 23 when installing the lifting handle 2, and improving the installation convenience of the lifting handle 2.

[0056] Alternatively, if Figure 3 As shown, the lifting portion 22 extends along the length direction of the elastic arm 23, and a lifting groove 221 is provided on one end of the lifting portion 22 away from the elastic arm 23. The lifting handle 2 is used as a force-applying component for lifting or lowering the slice rack body 1. The lifting groove 221 is provided on the lifting portion 22 of the lifting handle 2, which can increase the force-applying points and facilitate holding when lifting.

[0057] In order to improve the connection stability between the lifting handle 2 and the slice holder body 1, optionally, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the slice rack 100 further includes two clamping plates 3 located outside the slice rack body 1 . The two clamping plates 3 are arranged opposite to each other and connected to the second rack body 14 . The two clamping plates 3 are used to clamp the lifting handle 2 .

[0058] In the second usage state of the slicing rack 100, the lifting handle 2 is connected to the second connecting portion 12 located on the second frame body 14 through the first connecting portion 21. Since a long hole 141 is formed on the second frame body 14, and the second clamping hole 171 is arranged on the hole wall of the long hole 141, at this time, the two clamping plates 3 located outside the slicing rack body 1 can clamp the lifting handle 2 when the lifting handle 2 is connected to the second frame body 14, thereby limiting the freedom of the lifting handle 2 along the first direction X and improving the connection stability of the lifting handle 2.

[0059] Furthermore, since the lifting handle 2 is protruding from the slice rack body 1, when the lifting handle 2 is connected to the second clamping hole 171 by means of the elastic arm 23, only the elastic arm 23 serves as a connecting structure between the lifting portion 22 and the second frame body 14, and the two clamping plates 3 can clamp the lifting handle 2 at the same time, so that in addition to the connection between the clamping portion 211 and the second clamping hole 171, the lifting handle 2 and the second frame body 14 can also be connected through the two clamping plates 3, thereby further improving the connection strength between the lifting handle 2 and the slice rack body 1.

[0060] Alternatively, if Figure 4 As shown, the slice frame body 1 has a first central plane 4 parallel to the first direction X and a second central plane 5 parallel to the second direction Y, the second connecting portion 12 is located in the first central plane 4, and the third connecting portion 17 is located in the second central plane 5. The center lines of the two first frames 13 arranged opposite to each other in the second direction Y are both located in the first central plane 4, and the center line of the second frame 14 in the first direction X is located in the second central plane 5. The second connecting portion 12 is arranged in the first central plane 4, and the third connecting portion 17 is arranged in the second central plane 5, so that when the lifting handle 2 is connected to the second connecting portion 12 or the third connecting portion 17 through the first connecting portion 21, the weight of the slice frame body 1 on both sides of the lifting handle 2 is always equal, which is conducive to maintaining the stability of the slice frame body 1 during the lifting or lowering process.

[0061] As a second aspect provided by the present disclosure, the present disclosure provides a slice staining device, including a staining box and the above-mentioned slice rack 100.
