[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] Example 1

[0030] like Figures 1 to 4 This utility model provides a chromosome scanning component, including a fixture 1, a scanning component 3, and at least one magnifying lens 2. The magnifying lens 2 is connected to the fixture 1 through a first connecting component 4. The first connecting component 4 is provided with at least one mounting position 421. The number of magnifying lenses 2 is equal to the number of mounting positions 421 and is fixedly installed at the mounting positions 421. The scanning component 3 is connected to the fixture 1 through a second connecting component 5, and the scanning component 3 is located directly above the magnifying lens 2.

[0031] The beneficial effects of this embodiment are as follows: By adopting this mounting structure, the magnifying lens 2 is fixedly mounted on the first connecting component 4 without the need for rotation switching. This can improve the technical problem in the prior art where the high-frequency rotation of the turntable may lead to a decrease in the rotational accuracy of the turntable, which will directly affect the scanning accuracy of the microscopic scanning equipment. Furthermore, the magnifying lens 2 is connected to the mounting frame 1 through the first connecting component 4, and the scanning component 3 is connected to the mounting frame 1 through the second connecting component 5. This can improve the technical problem in the prior art where the camera, turntable, and magnifying lens are all mounted on the same mounting frame 1, which increases the load on the mounting frame 1 and affects the high-precision requirements of the scanning equipment.

[0032] The number of scope 2 and mounting position 421 can be one, two, three, or four, etc.

[0033] Specifically, in use, the scanning component 3 is moved along the X direction to be directly above different magnification lenses 2 by the drive of the second connecting component 5, so as to cooperate with the magnification lens 2 of the corresponding required magnification. The vertical distance between the corresponding magnification lens 2 and the scanning component 3 can be adjusted by the drive of the first connecting component 4.

[0034] The number of scopes 2 can be two, three, or four, and the magnification of each scope 2 is different. For example, in the figure, there are two scopes 2, and the two scopes 2 are a 10x scope and a 100x scope, respectively.

[0035] Example 2

[0036] like Figures 2 to 4 Based on embodiment 1, the first connecting component 4 includes a vertical linear drive 41 mounted on the fixed frame 1, and the magnifying lens 2 is mounted on the drive end of the vertical linear drive 41.

[0037] The beneficial effect of adopting the preferred solution in the above embodiments is that the magnifying lens 2 is moved in the vertical direction by driving the first connecting component 4, thereby adjusting the vertical distance between the corresponding magnifying lens 2 and the scanning component 3.

[0038] Based on the above embodiments, as one of the parallel solutions, the vertical linear drive component 41 includes a first mounting base 411 mounted on the fixed frame 1, a first motor 412 fixedly mounted on the first mounting base 411, a first lead screw 413 with one end connected to the output shaft of the first motor 412, and a first slide block 414 threadedly connected to the first lead screw 413. The first lead screw 413 extends vertically and both its upper and lower ends are rotatably connected to the first mounting base 411. The first slide block 414 is vertically slidably connected to the first mounting base 411. The magnifying lens 2 is fixedly mounted on the first mounting base 411.

[0039] In use, the first motor 412 is started, driving the first lead screw 413 to rotate, causing the first slide block 414 to move in the vertical direction, which in turn drives the magnifying lens 2 to move, adjusting the vertical distance between the corresponding magnifying lens 2 and the scanning component 3.

[0040] A back support plate is fixedly connected to the top of the mounting bracket 1. The back support plate is also fixedly connected to the back of the first mounting base 411 to improve the installation stability of the first mounting base 411.

[0041] Based on the above embodiments, as a second parallel option, the vertical linear drive component 41 can also be a linear drive mechanism such as an electric cylinder or a pneumatic cylinder.

[0042] Example 3

One end of the first fixing plate 42 is connected to the driving end of the vertical linear drive member 41, and the other end extends laterally directly below the scanning member 3. The other end of the first fixing plate 42 is vertically through-hole provided with at least one mounting position 421.

[0044] The beneficial effect of adopting the preferred solution in the above embodiments is that the magnifying lens 2 is stably installed by the first fixing plate 42. When the vertical linear drive 41 is started, it drives the first fixing plate 42 to move vertically, so as to simultaneously move the magnifying lens 2 in the vertical direction and adjust the vertical distance between the magnifying lens 2 and the scanning component 3.

[0045] One end of the first fixed plate 42 is fixed to the first slide block 414 of the vertical linear drive member 41.

[0046] Example 4

[0047] like Figure 2 and Figure 3 Based on embodiments 1-3, the first connecting component 4 further includes a support plate 43, and the support plate 43 is simultaneously fixedly connected to the driving end of the vertical linear drive component 41 and the first fixing plate 42.

[0048] The beneficial effect of adopting the preferred solution in the above embodiments is that the strength of the installation structure of the first fixing plate 42 is improved by the support plate 43, the straightness of the cantilever formed by the first fixing plate 42 is guaranteed, and the magnifying glass 2 maintains a stable installation state.

[0049] As a specific embodiment of the above, the support plate 43 is generally triangular in shape, and its two right-angled sides are respectively fixedly connected to the upper side of the first fixed plate 42 and the first slide block 414 of the vertical linear drive member 41 by bolts or screws.

[0050] Example 5

[0051] like Figures 2 to 4 Based on embodiments 1-4, at least two magnifying lenses 2 and mounting positions 421 are provided, and the mounting positions 421 are arranged laterally at intervals; the second connecting component 5 includes a second slide 51 and a second fixing plate 52. One end of the second slide 51 is connected to the fixing frame 1, one end of the second fixing plate 52 is slidably connected to the second slide 51 along the arrangement direction of each mounting position 421, and the other end extends above the straight line formed by each magnifying lens 2, and the scanning component 3 is installed on the other end of the second fixing plate 52.

[0052] The beneficial effect of adopting the preferred solution in the above embodiments is that, in use, by making the second fixing plate 52 slide on the second slide block 51, the scanning component 3 is driven to slide synchronously, so that the scanning component 3 moves directly above the different magnification lenses 2, so as to achieve cooperation with the corresponding magnification lens 2.

[0053] In this embodiment, the number of scopes 2 can be two, three, or four, and the magnification of each scope 2 is different. For example, in the figure, two scopes 2 are shown, and the two scopes 2 are a 10x scope and a 100x scope, respectively. There are two mounting positions 421, and the two scopes 2 are mounted in two mounting positions 421 respectively.

[0054] Based on the above embodiment, a shelf 511 is slidably connected to the second slide block 51, and one end of the second fixing plate 52 is detachably connected to the shelf 511 to realize the installation of the second fixing plate 52. Specifically, the shelf 511 has a "U" shaped structure, and one end of the second fixing plate 52 is adapted to and extends into the opening of the shelf 511, and a screw threaded to the shelf 511 is inserted into the second fixing plate 52 to realize the limiting and fixing of the second fixing plate 52.

[0055] Example 6

[0056] like Figures 2 to 4 The second connecting component 5 also includes a transverse linear drive 53 connected to the fixed frame 1, and the drive end of the transverse linear drive 53 is connected to the second fixed plate 52.

[0057] The beneficial effect of adopting the preferred solution in the above embodiments is that the second fixed plate 52 is stably driven by the transverse linear drive member 53, and the stability of the second fixed plate 52 after it moves into place is ensured, thereby ensuring that the scanning member 3 and the corresponding magnifying lens 2 maintain stable cooperation after they move into place, so as to ensure scanning accuracy.

[0058] Based on the above embodiments, the second connecting assembly 5 further includes a side plate 54, which is fixedly connected to the side of the fixing frame 1 and extends and is fixedly connected to the other end of the second slide block 51. A transverse linear drive member 53 is fixedly mounted on the side plate 54. The side plate 54 forms a cantilever structure supporting the second slide block 51, improving the structural strength of the second slide block 51, ensuring the straightness of the cantilever structure formed by the second slide block 51, and ensuring that the scanning member 3 only slides along the extension direction of the second slide block 51.

[0059] As one of the parallel solutions, the transverse linear drive 53 includes a second motor 531 fixedly mounted on the fixed frame 1 via a side plate 54, a second lead screw 532 with one end connected to the output end of the second motor 531, and a connecting plate 533 with one end threaded to the second lead screw 532. The other end of the connecting plate 533 is fixedly connected to the second fixed plate 52.

[0060] In use, the second motor 531 is started, driving the second lead screw 532 to rotate, so that the connecting plate 533 slides on the second slide block 51, and the scanning component 3 moves directly above the different magnification lenses 2, so as to cooperate with the lens 2 of the corresponding required magnification.

[0061] The connecting plate 533 is generally L-shaped, with one end extending vertically and threaded to the second lead screw 532, and the other end extending horizontally and fixedly connected to the second fixing plate 52.

[0062] As a second alternative, the transverse linear drive component 53 can also be a linear drive mechanism such as an electric cylinder or a pneumatic cylinder.

[0067] like Figure 2 and Figure 3Based on embodiments 1-7, the other side of the second fixing plate 52 has a transverse groove 522 that connects to the mounting hole 521, and the upper side of the other end has a vertical groove 523 that connects the mounting hole 521 and the transverse groove 522. The other side of the second fixing plate 52 has an insertion hole 524 that connects to the vertical groove 523. The groove wall of the vertical groove 523 also has a threaded hole facing the insertion hole 524. The insertion hole 524 is used to insert a fastener that is threaded to connect to the threaded hole.

[0068] The beneficial effect of adopting the preferred solution in the above embodiments is that when installing the scanning component 3, the lower end of the scanning component 3 is inserted into the mounting hole 521, and then the fastener is inserted into the insertion hole 524 and simultaneously threaded into the threaded hole. In this way, the scanning component 3 is quickly pressed and installed, and when it needs to be removed, the fastener is removed, and the scanning component 3 can be pulled out from the mounting hole 521, making disassembly and assembly quick.

[0069] The fastener can be a screw.

[0070] Example 9
