Problems solved by technology
However, in the existing optical trainer, the left and right lens assemblies will interfere with each other when adjusting the distance or the axial direction. Spacing between lens components
In addition, there is usually a dial on the optical training instrument to display the longitudinal movement distance of the objective lens. When the distance between the left and right lens assemblies is adjusted, the dial will also rotate, which will affect the accurate display of the movement distance of the objective lens on the dial.
[0003] In order to adjust the left and right lens components to the final required state, it is necessary to perform multiple adjustments during the adjustment of the two, which is inconvenient to operate and brings unnecessary troubles

Embodiment Construction
[0038] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0039] Such as figure 1 , Figure 3-5 As shown, the optical trainer of an embodiment of the present invention is used for visual training, and it may include a housing 10, two groups of lens assemblies 20 disposed in the housing 10, a distance adjustment assembly 30, and two groups of lens assemblies respectively corresponding to Two sets of movement adjustment components 40 and two sets of indication components 50 are provided at 20.
[0040] The two groups of lens assemblies 20 correspond to the left eye and the right eye respectively, and the distance adjusting assembly 30 is used to adjust the distance between the two groups of lens assemblies 20 to suit the interocular distance (pupillary distance) of different tr...

The invention discloses an indicating assembly, a moving adjusting and indicating linkage mechanism and an optical training instrument. The indicating assembly comprises a dial, meshing teeth arrangedon the periphery of a sleeve of a shot assembly of the optical training instrument and a gear set which is arranged on the shot assembly and located between the dial and the meshing teeth and can move along with the shot assembly; scale meshing teeth distributed in the circumferential direction are arranged on the face, towards the shot assembly, of the dial; the axial length of a gear part meshed with the scale meshing teeth in the gear set is larger than or equal to the moving distance of lens assemblies in the pupillary distance adjusting direction. According to the indicating assembly, the moving adjusting and indicating linkage mechanism and the optical training instrument, in the optical training instrument, the indicating assemblies are not movably linked with the shot assemblies,accurate displaying of moving distance of objective lenses is guaranteed, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of optical instruments, in particular to an indication component for an optical trainer, a movement adjustment and indication linkage mechanism and an optical trainer using the mechanism. Background technique [0002] In the existing optical trainer for visual training, the distance between the left and right lens assemblies can be adjusted according to the trainer's eye distance, and can also be adjusted in the axial direction according to the trainer's diopter requirements. However, in the existing optical trainer, the left and right lens assemblies will interfere with each other when adjusting the distance or the axial direction. Spacing between lens components. In addition, the optical trainer is usually provided with a dial to display the longitudinal movement distance of the objective lens. When the distance between the left and right lens assemblies is adjusted, the dial will also rotate, which will ...
