Description

Technical Field

[0001] The invention relates to the field of microscopes, and in particular to an optical microscope based on ergonomic viewing angle optimization. Background Art

[0002] Most of the eyepieces of current optical microscopes are at a 45° angle or perpendicular to the horizontal plane. For users, the eyepiece is at a 45° angle. Due to the different heights of the desktop, it is impossible to ensure that the eyepiece is exactly at the height of the user's eyes. Therefore, the user often has to bend over to make the eyes fit the eyepiece, and excessive bending can easily cause damage to the user's cervical spine, cervical bone hyperplasia, intervertebral disc herniation, and easily cause damage to the user's shoulders and pain. For microscopes with eyepieces perpendicular to the horizontal plane, it is even more inconvenient for users to use them, and they often need to bend their upper body significantly to make the eyes fit the eyepiece. Compared with microscopes with eyepieces at a 45° angle, this type of microscope is more inconvenient to use and does not meet ergonomic requirements.

[0003] CN202411121650.1 discloses an optical microscope with a stable anti-deflection structure, whose eyepiece is arranged perpendicular to the horizontal plane, and CN202410430260.6 solves the problem that the height of the optical microscope cannot be adjusted according to the height of the user. However, since the eyepiece still adopts a 45° angle design, the user still needs to bend down to fit the eyes and the eyepiece when using it. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an optical microscope based on ergonomic viewing angle optimization. The eyepiece is designed with a 30-degree angle, which can greatly alleviate the pressure on the user's cervical spine caused by long-term use of the microscope and reduce the user's fatigue.

[0005] In order to solve the above technical problems, the technical solution of the present invention is an optical microscope based on ergonomic perspective optimization, including an eyepiece assembly, a prism component, a prism frame, a platform, a knob device, and an objective lens assembly.

The eyepiece is nested in the eyepiece mounting frame, and a first reflector is arranged at the bottom of the eyepiece mounting frame, and a second reflector is arranged obliquely above the eyepiece mounting frame. A first objective lens hole is arranged at the rear end of the prism frame, and the objective lens hole is connected with the platform and the objective lens assembly. The prism component includes a first prism, a second prism and a third prism. The front plane of the first prism is opposite to the objective lens hole, the inclined surface of the first prism is opposite to one end of the front plane of the second prism, and the other end of the front plane of the second prism is opposite to an inclined surface of the third prism. The other inclined surface of the third prism is obliquely arranged on the side of the second reflector.

[0006] As a further improvement, the prism frame is provided with a recess for mounting the second prism near the objective lens hole, and the second prism is embedded in the recess;

[0007] As a further improvement, the second reflector is fixed to the upper surface of the prism frame through a fixing frame, the fixing frame is in a quasi-annular shape, a supporting portion protruding toward the center point is provided on the inner side of the annular ring, the second reflector is provided on the surface of the supporting portion, and a limiting plate is provided on the surface of the fixing frame.

[0022] like Figure 1-6As shown, an optical microscope based on ergonomic perspective optimization includes an eyepiece assembly 1, a prism member 2, a prism frame 3, a platform 4, a knob device 5, and an objective lens assembly 6. The objective lens assembly 6 is arranged below the platform 4. Since the field targeted by the present invention is the field of electronic product maintenance, the magnification requirement is lower than that of a medical microscope, so there is no excessive restriction on the objective lens assembly 6, as long as it is a conventional objective lens assembly 6. Of course, since there are variable magnification objective lenses on the market, they are also suitable for the present invention. As for the installation relationship therein, it is not complicated for those skilled in the art, and will not be described here.

[0023] The present invention is mainly aimed at the design of the optical path, and the optical path on the objective lens is relatively stable, so the present invention is mainly focused on the design of the optical path between the platform and the eyepiece.

[0025] In order to facilitate the loading and disassembly of the second reflector 33, the second reflector 33 is fixed to the upper surface of the prism frame 3 through a fixing frame 35. The fixing frame 35 is in a quasi-annular shape, and a support portion 351 protruding toward the center point is provided on the inner side of the annular ring.

[0027] As mentioned above, the present invention has no strict restrictions on the objective lens assembly 6, as long as it meets general requirements, and the structure in this embodiment is only used for example rather than limitation.
