Problems solved by technology

[0004] However, the technical solutions adopted in these patents all use the shading frame fixed on a separate eyepiece, and the existing microscope eyepieces are generally arranged side by side as two, and the distance between the two eyepieces can also be adjusted to adapt to different microscope eyepieces. It is used by people with eye distance; therefore, continuing to use the technical solutions in the above patent documents will cause inconvenient operations such as adjustment and fixation of the shading frame

Embodiment 1

[0035] Refer to the manual attached Figure 1-8 , a light-shielding frame for observing pathological slices under a microscope of this embodiment includes an eyepiece fixing sleeve 1, a sliding connection assembly 2 and a light-shielding sleeve assembly 3, and the eyepiece fixing sleeves 1 are arranged in two and are respectively compatible with the eyepiece lens 4. Removal and connection, the shading sleeve assemblies 3 are arranged in two, the bottom ends of the two shading sleeve assemblies 3 are respectively fixedly connected with the top end of the eyepiece fixing sleeve 1, and the other end is turned to the outside and is fixedly connected with the sliding connection assembly 2. The cross section of the rear shading sleeve assembly 3 is set as an inverted trapezoid, and the sliding connection assembly 2 is slidably sleeved on the outside of the two eyepiece fixing sleeves 1, and drives the other end of the shading sleeve assembly 3 to do up and down reciprocating motion t...

Embodiment 2

[0052] Further, the end of the eyepiece fixing sleeve 1 close to the eyepiece is fixedly connected with a tube hoop, and the tube hoop is a clamp, a throat hoop or a holding hoop.

[0053] The implementation scenario is as follows: the eyepiece fixing sleeve 1 of the present invention can be fixed to the eyepiece by any one of a clamp, a throat clamp or a hoop, which is also very convenient to use, and other relatively convenient fixing methods can also be used.

[0054] Working principle: when the present invention is used, firstly fix the two eyepiece fixing sleeves 1 to the two eyepieces, after fixing, hold the two annular sleeve plates 21 with both hands, and press the fixing clip 8, then the sliding connection assembly can be performed. 2 slides up and down smoothly. When the sliding connection component 2 slides down, it drives the foldable shading sleeve 31 to continue to flip downward, so that the height between the foldable shading sleeve 31 and the lens can be adjuste...

Abstract

The invention discloses a light-shielding frame for microscope observation of pathological slices, specifically relates to the field of microscope auxiliary equipment, comprising an eyepiece fixing sleeve, a sliding connection assembly and a light-shielding sleeve assembly. Detachable connection, two shading sleeve assemblies are provided, the bottom ends of the two shading sleeve assemblies are respectively fixedly connected to the top of the eyepiece fixing sleeve, the other end is flipped outwards and fixedly connected to the sliding connection assembly, the shading after flipping The cross-section of the sleeve component is set as an inverted trapezoid, and the sliding connection component is slidably sleeved on the outside of the two eyepiece fixing sleeves. The shading frame of the present invention can be connected with two eyepieces, and by moving up and down to slide the connection assembly, the folding shading cover is turned up and down, so that the height adjustment of the folding shading cover from the lens can be realized, and the contact between the top surface of the folding shading cover and the eye socket can be realized. The adjustment of the area is suitable for different groups of people.

Description

technical field [0001] Embodiments of the present invention relate to the field of microscope auxiliary appliances, in particular to a light-shielding frame for observing pathological sections under a microscope. Background technique [0002] When observing rapid pathological slices from the operating room with a microscope, the glasses of general pathologists are viewed close to the eyepiece lens of the microscope. When observing objects with a microscope, the eyepiece, barrel, objective lens, and light aperture of the microscope must be on the same straight line. The light reflected by the reflector can reach the eyes through the light hole, objective lens, lens barrel and eyepiece in turn. The aperture below the slide can adjust the intensity of light transmission by adjusting the size of the aperture, but when the surrounding environment is strong The light of the eyepiece is easily reflected on the eyepiece glass lens, which affects the observation effect of the patholo...
