Description
Technical Field
[0001] The invention relates to the field of telescope design, and in particular to a binocular laser ranging telescope. Background Art
[0002] Currently, most laser rangefinders are monocular with a single lens and a low optical magnification. Their measurement distance is short, their functionality is limited, and their application scope is limited. Existing binocular laser rangefinders often use OLED displays, with no adjustable eyepiece distance. Imaging and observation of objects rely heavily on image processing technology, which places high demands on the imaging detector. These sensors also suffer from poor battery life and high costs. Laser rangefinders are currently transitioning from military technology to civilian applications, serving applications in military observation, outdoor exploration, geological exploration, and other fields, requiring lower costs while improving operability and observation comfort.

DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and technical effect of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses a binocular laser ranging telescope comprising a body assembly, an eyepiece assembly 1, an objective lens assembly 2, a battery assembly 3, a button assembly 4, and a rubber sheath 5. Metal parts such as the body assembly are primarily made of aluminum alloy to ensure strength while reducing weight. The components are rigidly connected via screws and threads, and exposed connections are sealed with sealant. The rubber sheath 5 covers the exterior. The overall structure is compact, stable, reliable, waterproof, and shockproof, ensuring stable operation even in complex environments. The button assembly 4 contains two buttons, one for distance measurement and one for angle measurement, making it convenient for handheld use and suitable for a wide range of applications.
[0017] like Figure 3The optical schematic diagram of the telescope of the present invention is shown. The telescope also includes a transparent display screen 6, a laser rangefinder module 7, a digital electronic compass 8, an optical axis adjustment assembly, and a prism assembly 11. The eyepiece assembly 1, prism assembly 11, and objective lens assembly 2 form a Porro telescope optical system, integrating white-light observation with data acquisition. Distant objects are imaged on the transparent display screen 6 through the objective lens assembly 2 and prism assembly 11, and then magnified by the eyepiece assembly 1 for human observation. Distance and angle measurement are performed by the laser rangefinder module 7 and the digital electronic compass 8, powered by a CR123 lithium battery 9 in the battery pack 3. After collecting data, the laser rangefinder module 7 and the digital electronic compass 8 convert the optical signal into an electrical signal via the main control circuit board 23. The data information is ultimately imaged on the transparent display screen 6, and magnified by the eyepiece assembly 1 for human observation. The laser rangefinder module 7 has a protective glass 10, which provides a wide range and high accuracy for distance and angle measurement.
[0018] like Figure 4 As shown, the lens assembly includes a left lens body 12, a right lens body 13, a central axis 14, a left lens cover 16, and a right lens cover 17. The left lens cover 16 and the right lens cover 17 are screwed to the left lens body 12 and the right lens body 13, respectively. The joints are sealed with sealant. The left lens body 12 and the right lens body 13 are connected by the central axis 14. The left and right lens bodies can rotate around the central axis 14 to achieve the eye distance adjustment function.
[0019] like Figure 5a and 5b As shown, the prism assembly 11 includes a prism frame 24, and an upper prism 25 and a lower prism 26 disposed on the prism frame 24. A spherical cylinder 30 is disposed on the prism frame 24 for optical axis adjustment.
[0020] like Figure 6 As shown, a spherical concave hole 31 corresponding to the spherical cylinder 30 is provided inside the left and right mirror bodies (12, 13) for stable installation and optical axis adjustment of the prism group 11.
[0021] like Figure 7 As shown, the optical axis adjustment assembly includes a compression spring 27, an adjustment screw 28, and a locking screw 29. The prism assembly 11 is mounted on the left and right mirror bodies (12, 13) respectively using the compression spring 27, the adjustment screw 28, and the locking screw 29. The entire product is then preliminarily installed. The optical axis is adjusted using an optical axis adjustment instrument. First, the locking screw 29 is tightened, and then the adjustment screw 28 is fine-tuned using an Allen wrench. The compression spring 27 provides a buffering and restoring force to align the left and right optical axes. To ensure distance measurement accuracy, the laser distance measurement module 7 is adjusted using an optical axis adjustment instrument. A gasket is added to the mounting portion of the laser distance measurement module 7, and the emission optical axis of the laser distance measurement module 7 is adjusted so that it coincides with the cross-section of the transparent display screen 6. The optical axis adjustment of the present invention uses a compression spring 27 and two screws to perform optical axis adjustment externally, which can reduce the number of disassembly and assembly times and improve adjustment efficiency.
[0022] like Figure 8 As shown, the eyepiece assembly 1 is equipped with an eye mask 15, which has the function of protecting human eyes. Figure 9 As shown, the central axis 14 and the ear holes of the left and right mirror bodies are tapered. The friction between the central axis 14 and the left and right mirror bodies is changed by adjusting the tension of the set screw 18 until the left and right mirror bodies rotate smoothly.
[0023] like Figure 10 and Figure 11 As shown, the objective lens group 2 includes a left objective lens 19 and a right objective lens 22. The left objective lens 19 and the battery assembly 3 are respectively connected to the left lens cover 16 through threads, wherein the battery assembly 3 is mainly composed of a CR123 lithium battery 9, a battery tube 20 and a battery cover 21.
[0024] The laser ranging module 7 and the digital electronic compass 8 are arranged on the right mirror cover 17. Correspondingly, a main control circuit board 23 is also provided on the right mirror cover 17. The laser ranging module 7 and the digital electronic compass 8 transmit the collected data to the transparent display screen 6 through processing by the main control circuit board 23, and the data is magnified by the eyepiece group 1 for observation by the human eye.
