[0013] Referring to the drawings, the specific implementation is as follows:
[0014] As Figures 1-2As shown, a laser rangefinder that is easy to adjust in all directions includes a transmitting lens 1, a transmitting adapter sleeve 2, a transmitting light source 3, a receiving lens 4, and a detector assembly 5. The transmitting lens 1 and the transmitting light source 3 are respectively installed at both ends of the transmitting adapter sleeve 2 along the axial direction. The transmitting light source 3 can emit a ranging laser to the target through the transmitting lens 1. The receiving lens 4 can receive the laser echo reflected by the target. The receiving lens 4 is located on one side of the transmitting lens 1 and the transmitting adapter sleeve 2 along the radial direction. The detector assembly 5 is located on one side of the transmitting light source 3 along the radial direction. The detector assembly 5 is connected to one end of the receiving lens 4 along the axial direction so that the detector assembly 5 can calculate the target distance based on the laser echo.
[0015] like Figures 2-3 As shown, there is a gap between the opposite sides of the transmitting adapter sleeve 2 and the receiving lens 4. A steel ball 8 is placed in the gap. The diameter of the steel ball 8 is larger than the width of the gap. The two sides of the steel ball 8 are respectively locked in the spherical grooves on the side of the transmitting adapter sleeve 2 and the side of the receiving lens 4. Two sets of connecting screws 7 are also screwed on the opposite sides of the transmitting adapter sleeve 2 and the receiving lens 4. Each set of connecting screws 7 has two screws. The length direction of the four connecting screws 7 is perpendicular to the length direction of the transmitting adapter sleeve 2 and the receiving lens 4. The two sets of connecting screws 7 are located on both sides of the gap, which can restrict the steel ball 8 from detaching from the gap and restrict the relative displacement of the transmitting adapter sleeve 2 and the receiving lens 4.
[0016] In this embodiment, the transmitting adapter sleeve 2 and the receiving lens 4 are connected by two sets of connecting screws 7. However, the opposite sides of the transmitting adapter sleeve 2 and the receiving lens 4 are not directly attached, but there is a gap and a steel ball 8 is placed in the gap. The steel ball 8 is in contact with the spherical grooves on the side of the transmitting adapter sleeve 2 and the side of the receiving lens 4. The steel ball 8 can realize the relative rotation of the transmitting adapter sleeve 2 and the receiving lens 4 at different angles, realize the fine adjustment of the installation angle of the transmitting lens 1 and the receiving lens 4, and give the laser rangefinder a universal adjustment function, which can conveniently and quickly make fine adjustments to the pitch angle of the transmitting lens 1 and the receiving lens 4.
[0017] When the adjustment angle is small, since the diameter of the connecting screw 7 is usually smaller than the diameter of the through hole through which it is inserted, the connecting screw can be directly inserted into the existing through hole. When the adjustment angle is large, different through holes can be pre-drilled on the transmitting adapter sleeve 2 and the receiving lens 4, and the connecting screw 7 can be inserted into the different through holes. Finally, the lens frame 6 is installed on the outside of the transmitting lens 1 and the receiving lens 4, which can simultaneously meet the requirements for fine adjustment of the pitch angle or adjustment of a large angle.
