DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 and Figure 2 As shown, the embodiment of the utility model discloses a microscope device with an optical path port 12 , which includes: a microscope body 10 , a light shield 30 , an external optical path system 40 and a telescopic support mechanism 20 .

[0023] The microscope body 10 has a stage 11 at the bottom, and a sample tray is provided above the stage 11 for placing a slide carrying a biological sample. An optical port 12 is provided on the side wall of the stage 11. The optical system between the optical port 12 and the sample tray may be referred to as an internal optical system. The optical port 12 is a circular port.

[0024] The telescopic support mechanism 20 is located at the bottom of the stage 11, that is, the microscope body 10 is placed on the workbench 100 by means of the telescopic support mechanism 20. The telescopic support mechanism 20 is used to adjust the height of the stage 11, so as to adjust the height of the optical path port 12 from the workbench 100. The telescopic support mechanism 20 can be configured into a variety of types. The embodiment of the utility model provides a type. Specifically, the telescopic support mechanism 20 includes four legs 21, and the four legs 21 are arranged in a matrix. At the bottom of the mirror stage 11, each leg 21 includes a screw sleeve 212 and a screw rod 211. The screw sleeve 212 is located above the screw rod 211. The lower end of the screw rod 211 is supported on the table top. The screw sleeve 212 is fixed to the bottom of the mirror stage 11. The upper end of the screw rod 211 extends into the screw sleeve 212 and forms a threaded fit with the screw sleeve 212. The height of the entire leg 21 can be adjusted by screwing the screw rod 211. The horizontality and height of the mirror stage 11 can be adjusted by comprehensively adjusting the heights of the four legs 21.

[0025] The light shield 30 is located at one side of the microscope body 10 and is placed on the workbench 100. The light shield 30 is made of a non-transparent material. Preferably, the light shield 30 is a cubic structure, and a valve 31 is arranged on the front wall of the light shield 30. One side wall of the light shield 30 is opposite to the stage 11. A docking port is provided on the side wall of the light shield 30. A light guide tube 50 is arranged between the docking port and the optical path port 12. Light from the optical path port 12 enters the light shield 30 through the inner hole of the light guide tube 50. In some preferred structures, the light guide tube 50 is configured as a telescopic tube. Specifically, the light guide tube 50 includes a first barrel 51 and a second barrel 52. The first barrel 51 and the second barrel 52 are partially overlapped and threadedly matched. In this way, the length of the light guide tube 50 can be adjusted by screwing the first barrel 51 or the second barrel 52, so as to adapt to the distance between the stage 11 and the light shield 30.

[0026] The external optical path system 40 is distributed to the light guide tube 50 and the light shield 30. The external optical path system 40 is used to guide the light from the internal optical path system to the light shield 30. The image acquisition device 200 (such as a camera, a video camera) is located in the light shield 30 and is used to collect the light guided by the external optical path system 40, so as to obtain an image of the biological sample. The external optical path system 40 includes a plurality of guide rods 43, a slide 42 sliding along the light guide rods, and a plurality of lenses 41 (such as a convex lens 41, a concave lens 41, etc.) mounted on the slide 42. The external optical path system 40 is an extended optical path system. Through the external optical path system 40, the image acquisition device 200 can more easily obtain a clear biological sample image.

[0027] The microscope device with the optical path port 12 provided by the utility model has at least the following advantages:

[0028] 1. It enables a larger image acquisition device 200 (such as a camera or a video camera) to still fit with the microscope body 10.

[0029] 2. By adding the light shield 30 and the external light path system 40, the light path of the original microscope body 10 is expanded, thereby being able to meet various requirements for image acquisition.
