[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 5 As shown:

[0029] The utility model provides a multi-screen switchable monocular telescope rangefinder, comprising a rangefinder body 11 and a mounting cylinder 12 mounted at the bottom of the rangefinder body 11, wherein a laser emitting component is mounted in the mounting cylinder 12 for emitting a ranging laser to a target, a laser receiving component is correspondingly arranged in the rangefinder body 11 for receiving a reflected laser signal, the laser receiving component comprises a prism group 31, and the prism group 31 is mounted in the rangefinder body 11 for reflecting the received laser signal. In order to realize multi-screen display, a mounting cavity 13 is arranged at the bottom of the rangefinder body 11, the position of the mounting cavity 13 is aligned with the built-in prism group 31, and a screen display component is correspondingly arranged in the mounting cavity 13.

[0030] Please refer to Figure 1 and Figure 2 As shown, a battery 14 is arranged at the bottom of the rangefinder body 11, a key circuit board 47 is arranged at the top, and a circuit board 48 is arranged on one side of the rangefinder body 11. The battery 14, the laser receiving component, the laser emitting component and the key circuit board 47 are all electrically connected to the circuit board 48; thereby, the circuit board 48 is used to provide continuous and stable power support for the built-in laser receiving component and the laser emitting component. Since laser emission and reception require a large amount of electric energy to drive, using the battery 14 as a power source can effectively avoid the problem of decreased ranging accuracy due to unstable power supply. Moreover, compared with an external power supply, the built-in battery 14 can make the entire rangefinder smaller and more convenient to hold.

[0031] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, the laser emitting assembly includes a laser emitting module 21. The laser emitting module 21 is arranged in the mounting cylinder 12. The laser emitting module 21 is electrically connected to the circuit board 48 to obtain the power supply of the battery 14, which can ensure the stability of the laser emission. In addition, an emitting lens fixture 22 is fixed to one end of the mounting cylinder 12 by a thread, and a laser emitting optical module 23 is correspondingly installed in the emitting lens fixture 22. In order to realize the laser emission, the laser emitting module 21 is facing the built-in laser emitting optical module 23, and the laser is emitted to the target through the laser emitting optical module 23.

[0032] Please refer to Figure 2 As shown, the laser receiving assembly also includes an objective lens group 32. An objective lens fixture 33 is fixed to one end of the rangefinder body 11 by a thread. The objective lens group 32 is installed in the objective lens fixture 33, and the objective lens group 32 can collect light. At the same time, the prism group 31 is fixed in the rangefinder body 11 by a prism fixture 34. The prism group 31 mainly refracts the collected light. The objective lens group 32 collects the returned laser inward, and the prism group 31 refracts the light.

[0033] Please refer to Figure 2 and Figure 5 As shown, in order to achieve accurate distance measurement, a laser receiver module 35 is arranged at the bottom of the rangefinder body 11, and the receiving surface of the laser receiver module 35 faces the bottom of the prism group 31 located in the body, so that the light refracted by the prism group 31 can be directly incident on the laser receiver module 35; at the same time, the laser receiver module 35 also obtains output power from the battery 14 through electrical connection with the circuit board 48, and the stable power supply ensures the efficient operation of the receiver.

[0034] Please refer to Figure 2 and Figure 4 As shown, the screen display component includes a reflective OLED liquid crystal 41, which is installed in the installation cavity 13 and can clearly display the distance measurement result; at the same time, a reflector 42 is also provided at the bottom of the installation cavity 13, and a reflector adjustment module 43 is further installed below the reflector 42. In order to transmit light, a lens group 44 is also provided in the installation cavity 13, and one end of the lens group 44 faces the reflector 42, and the other end is connected to the prism group 31, which ensures that the distance measurement result displayed on the reflective OLED liquid crystal 41 can be smoothly transmitted from the prism group 31 to the image surface of the objective lens group 32.

[0035] Please refer to Figure 2 and Figure 3 As shown, an eyepiece group 15 is provided at one end of the rangefinder body 11, and a transmissive LCD liquid crystal 46 is provided between the eyepiece group 15 and the rangefinder body 11, which can display the distance measurement result. The transmissive LCD liquid crystal 46 and the reflective OLED liquid crystal 41 are both electrically connected to the circuit board 48; through the key circuit board 47, the user can switch between the reflective OLED liquid crystal 41 and the other transmissive LCD liquid crystal 46, which enables the rangefinder to select the best display mode in different indoor and outdoor environments; at the same time, the key circuit board 47 can also adjust the font color and brightness to adapt to viewing under different light conditions.

[0036] The eyepiece group 15 is also provided with an eyepiece focusing wheel 16. By rotating the eyepiece focusing wheel 16, the user can focus on the target conveniently and quickly to clarify the observation range; the rangefinder uses a screen display component and simultaneously adopts a reflective OLED liquid crystal 41 and a transmissive LCD liquid crystal 46 for multi-screen display, solving the problem that the traditional monocular telescope rangefinder can only have a single display.

[0037] The specific usage and function of this embodiment are as follows: when in use, the laser is emitted by the laser emission module 21, passes through the laser emission optical module 23, hits the target surface and then is reflected back, passes through the objective lens group 32 and the prism group 31, and reaches the laser receiver module 35, so that the distance measurement result can be obtained; and the transmissive LCD liquid crystal 46 is installed between the eyepiece group 15 and the prism group 31, and the measurement result is displayed on the imaging focal plane of the eyepiece group 15; the measurement result display of the installation position of the reflective OLED liquid crystal 41 is through the refraction and reflection of the reflector 42, the optical path adjustment of the lens group 44, and the refraction and reflection of the prism group 31, and the measurement result displayed by the reflective OLED liquid crystal 41 can be observed in the eyepiece group 15, and the installation position of the reflective OLED liquid crystal 41 is the position of another focal plane formed by the above lens group 44, the prism group 31 and the reflector 42; the measurement result display of the transmissive LCD liquid crystal 46 and the reflective OLED liquid crystal 41 can be switched and displayed by the control of the key circuit board 47.

[0038] During production and installation, the objective lens group 32 and the prism group 31 are adjusted and fixed by the objective lens fixing member 33 and the prism fixing member 34 respectively; the laser emission optical module 23 is adjusted and fixed by the emission lens fixing member 22, so that the laser emission and return reception can achieve the best optical signal effect.

[0039] During production and installation, the reflector 42 is adjusted by adjusting the reflector adjustment module 43, and the lens group 44 is adjusted through the lens fixing member 45 and then fixed, so that the display of the reflective OLED liquid crystal 41 can achieve the best display effect when observed through the eyepiece group 15; when in use, the observation target and display clarity can be adjusted through the eyepiece focusing wheel 16.
