[0002] The electronic eyepiece is a photoelectric microscopic conversion device specially developed for microscope imaging. Utility model CN207780347U discloses a microscope electronic eyepiece, including a docking frame, an eyepiece assembly, an eyepiece upper shell, a signal line and a PCB board. The eyepiece assembly includes an eyepiece, an external thread, a long bolt, a short bolt and an eyepiece bottom shell. The external thread is wrapped around the outside of the eyepiece, and the eyepiece bottom shell is arranged at the end of the eyepiece; the eyepiece upper shell and the eyepiece bottom shell are connected by screws to form a cavity, the PCB board is arranged in the cavity, and the signal line is connected to the PCB board. The PCB board is provided with a photosensitive chip, a socket, an indicator light and a small screw hole. The photosensitive chip is arranged in the middle of one side of the PCB board, the socket and the indicator light are arranged on the reverse side of the photosensitive chip, and the small screw hole is connected to the short bolt with screws.

[0003] At present, in the experimental operation test involving a microscope, students need to first adjust the focal length of the microscope until the image is clear to the naked eye, then remove the optical magnifying element of the microscope, and then insert the electronic eyepiece into the microscope to transmit the real-time image of the microscope to the computer monitor. However, the electronic eyepiece of the prior art has a focal length different from the physical focal length of the lens when the student focuses once, so a clear image cannot be obtained after the electronic eyepiece is inserted into the microscope, and a second focusing is still required. Utility Model Content

[0004] In order to make up for the deficiencies in the prior art, the utility model provides a special electronic eyepiece for examination, which can clearly transmit images without secondary focusing during experimental operation examinations.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An electronic eyepiece specially used for examination comprises a signal output element, on which an automatic zoom camera is arranged, and at the front end of which an optical magnifying element is arranged, and the magnification of the optical magnifying element is the same as that of an eyepiece of an experimental microscope.

[0007] Furthermore, the focal length variation range of the automatic zoom camera is 0-5mm.

[0008] As a specific implementation scheme, the automatic zoom camera is separately connected to the optical magnifying element.

[0009] Furthermore, the optical magnifying element is an eyepiece, the eyepiece is connected to a shell, and the signal output element is arranged in the shell.

[0010] Furthermore, the shell includes a front shell and a rear cover that are buckled together, the front shell is provided with a connecting hole, the eyepiece is threadedly connected to the connecting hole, and the rear cover is provided with a wire hole.

[0011] As another specific implementation scheme, the automatic zoom camera is integrally connected to the optical magnifying element.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model is a special electronic eyepiece for examination, which is provided with an optical magnifying element and an automatic zoom camera. The magnification of the optical magnifying element is the same as that of the eyepiece of a microscope for examination. The automatic zoom camera can automatically focus within a certain range, so that during the examination, students only need to adjust the focus once and then insert the electronic eyepiece to output a clear picture, which reduces the operation steps and is more convenient and quick to use.

The optical magnifying element 1 is preferably an eyepiece, and its magnification is the same as that of the eyepiece of an experimental microscope. For example, if the eyepiece of the experimental microscope is a 10x eyepiece, a 10x eyepiece is selected. The front shell 2 and the rear cover 4 are buckled to form a shell, and the optical magnifying element 1 is connected to the shell. The signal output element 3 is arranged in the front shell 1, and is preferably a USB module, but is not limited to other signal output modules.

[0020] Specifically, the front shell 2 is a square frame structure, and a connection hole 21 is provided on one side thereof, and the optical amplifier 1 is threadedly connected to the connection hole 21. The signal output element 3 is provided with an automatic zoom camera 31, and the automatic zoom camera 31 is opposite to the optical amplifier 1 to shoot the image inside the optical amplifier 1.
