Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be understood by the person skilled in the art.It should be noted that the explanation for these embodiments is used to help
Understand the present invention, but and does not constitute a limitation of the invention.In addition, involved in the various embodiments of the present invention described below
And to technical characteristic can be combined with each other as long as they do not conflict with each other.
The present embodiment provides one kind to be used for microscopical non-contact wide-angle inverted image device, is used to be mounted on microscope,
To make it have the function of observation human eye, such as funduscopy.Shown in referring to Fig.1, which is wrapped
Include bracket 11, for connecting microscopical connection ring 13, inverted image mirror 14 and wide-angle lens 15.The connection ring 13 is set to the branch
The upper end of frame 11.The inverted image mirror 14 is arranged on the bracket 11, and the wide-angle lens 15 is arranged in the bracket 11 or institute
It states on inverted image mirror 14, the inverted image mirror 14 is between the connection ring 13 and the wide-angle lens 15.
Specific in the present embodiment, the non-contact wide-angle inverted image device 1 and microscope are threadedly coupled.In the connection ring 13
It is provided with the thread bush 12 for being threadedly engaged with the microscope.
The inverted image mirror 14 is rotatablely arranged on the bracket 11.The non-contact wide-angle inverted image device 1 has work
Make state and off working state, by rotating inverted image mirror 14 and wide-angle lens 15 relative to bracket 11, so as in working condition and
Switch between off working state, convenient for users to when filling 1 without using non-contact wide-angle inverted image and setting, by inverted image mirror 14 and wide-angle lens
15 rotations, move on to outside sight.Specific in the present embodiment, the inverted image mirror 14 is set to the bracket 11 by focus adjusting mechanism 16
On, focus adjusting mechanism 16 is rotatably connected at bracket 11, and inverted image mirror 14 can be connected to focus adjusting mechanism 16 with being slidable in the vertical direction
On.The focus adjusting mechanism 16 includes focusing knob 160, and focus adjusting mechanism 16 may include the transmission mechanisms such as worm and gear, pass through rotation
Focusing knob 160 can drive inverted image mirror 14 to move up and down, so that the height of inverted image mirror 14 is adjusted, thus realize focusing, and it is convenient
It focuses, makes clearly observe eye ground under different multiplying.
The wide-angle lens 15 be it is multiple, the degrees of multiple wide-angle lens 15 is different, and multiple wide-angle lens 15 pass through
Shaft 17 is rotatably connected at inverted image mirror 14.When the non-contact wide-angle inverted image device 1 is in working condition, only one of them
The wide-angle lens 15 is located at the lower section of the inverted image mirror 14, can rotate selection by shaft 17 and use the wide-angle lens of different degrees
15.The axial line of shaft 17, which tilts, to be extended, and wide-angle lens 15 is aspherical mirror, and the center line of center line and shaft 17 makes up less than
90 degree of angle, thus when selected wide-angle lens 15 turns to the underface of inverted image mirror 14, the center line of wide-angle lens 14 can
With the optical axis coincidence of the non-contact wide-angle inverted image device 1.
As shown in Figure 1, when the non-contact wide-angle inverted image device is in working condition, wide-angle lens 15 is close to observed
The position of human eye, inverted image mirror 14 is located at the surface of wide-angle lens 15 and wide-angle lens 15 is aligned.
