[0030] Example:

[0031] As attached Figures 1 to 8 As shown:

[0032] The utility model provides a binocular telescope type rangefinder of reflective liquid crystal, the core of which is that a liquid crystal display component is independently arranged on one side of a first barrel 11, rather than being directly placed in an observation optical path, and includes a telescope body, the telescope body includes a first barrel 11 and a second barrel 12, a laser emitting component and a laser receiving component are respectively arranged in the first barrel 11 and the second barrel 12, a mounting groove 13 is opened on one side of the first barrel 11, a liquid crystal display component is arranged in the mounting groove 13, the liquid crystal display component includes a reflective OLED liquid crystal 21, a lens group 22 and a beam splitter prism 23, a reflective OLED liquid crystal 21 is arranged in the mounting groove 13, a lens group 22 is arranged on one side of the reflective OLED liquid crystal 21, and a beam splitter prism 23 is arranged on the side of the lens group 22 away from the reflective OLED liquid crystal 21. Compared with the traditional transmissive LCD display, the arrangement of the reflective OLED liquid crystal 21 can effectively avoid the obstruction and light loss of the observation optical path, and the lens group 22 and the beam splitter prism 23 are responsible for introducing the OLED display screen into the user's line of sight to form the final observation screen.

[0033] Please refer to Figure 3 , Figure 6 and Figure 8 As shown, a reflector 24 is specially arranged between the reflective OLED liquid crystal 21 and the lens group 22, so that the reflective OLED liquid crystal 21 and the lens group 22 can both face the reflector 24, and introduce the OLED display screen into the user's sight through the reflector 24 to form the final observation screen; by installing such a liquid crystal display component in the mounting groove 13 on the side of the first cylinder 11, not only the shielding and light loss of the traditional transmissive LCD on the observation light path are avoided, but also the optical performance of the whole machine is further optimized. In contrast, the layout of this reflective OLED liquid crystal 21 can maximize the light transmittance of the observation light path, thereby bringing users a better observation experience and better optical quality.

[0034] Please refer to Figures 4 to 8 As shown, the laser emitting assembly includes a laser emitting module 31, which is arranged on one side of the splitter prism 23, and a first prism group 32 is installed on the other side of the splitter prism 23. A first fixed prism assembly structure 33 is arranged in the first barrel 11, and the first prism group 32 is installed inside the first fixed prism assembly structure 33. A first fixed objective lens structure 34 is arranged in the first barrel 11, and a first objective lens 35 is arranged in the structure 34 of the first fixed objective lens. A first fixed field lens structure 36 is arranged in the first barrel 11, and a first field lens 37 is arranged in the structure 36 of the first fixed field lens. It is worth noting that these key optical elements, including the first prism group 32, the first objective lens 35 and the first field lens 37, are all arranged on the same straight line, which not only ensures the accuracy of laser emission, but also provides a good foundation for subsequent optical imaging.

The reflected light waves then pass through the second objective lens 42, the second field lens 44 and the second prism group 47 in sequence, and are finally received by the laser receiving module 45. The receiving module displays the measurement result on the reflective OLED liquid crystal 21. Specifically, the light reflected by the reflector 24 to the lens group 22 is refracted by the dichroic prism 23 and then refracted by the first prism group 32. The measurement result displayed by the reflective OLED liquid crystal 21 can be observed through the eyepiece group 18, providing intuitive measurement data for the user. During the assembly and debugging process, the performance of the first prism group 32, the first objective lens 35 and the first field lens 37 are optimized by debugging the combined structural member 33 of the first fixed prism, the structural member 34 of the first fixed objective lens and the structural member 36 of the first fixed field lens, ensuring that the laser emitting module 31 and the laser receiving module 45 can achieve the best measurement effect, and correcting the observation optical path of the left and right lens barrels.

Whether it is a close or long-distance target, the user can easily adjust it to obtain a clear observation experience.

[0041] Specific usage and function of this embodiment: This rangefinder can be used as a binoculars for observation, and can also measure the distance by operating the button 54. The measurement result is synchronously displayed in the field of view of the eyepiece. The user can measure while observing and read the measurement result directly in the eyepiece, and can adjust the clarity by focusing the central axis and use the diopter wheel to adjust the diopter difference caused by the different vision of the left and right eyes; when in use, the laser emitting module 31 emits a laser, which passes through the optical components of the first prism group 32, the first field lens 37 and the first objective lens 35 and then hits the target.
