[0044] like Figure 1-Figure 4 As shown, a laser rangefinder distance correction device disclosed in the present invention may include: a placement platform 1, a clamping assembly, a lifting assembly, a rotating assembly, a fine-tuning assembly and other components.

[0045] like Figure 2 and Figure 3 As shown, in the present disclosure, the fine-tuning assembly includes a supporting plate 6, a telescopic sleeve 61 is provided on one side of the supporting plate 6, a level 62 is provided on the top of the supporting plate 6, a rotating shaft 63 is fixedly connected to the other side of the supporting plate 6, a mounting block 8 is fixedly connected to the other end of the rotating shaft 63, a connecting ring 72 is provided on the other side of the mounting block 8, a connecting rod 75 is fixedly connected to the outer side of the connecting ring 72, and a pull ring 7 is fixedly connected to the other end of the connecting rod 75.

[0046] Therefore, both ends of the supporting plate 6 are fixedly connected with the rotating shaft 63. The rotating shaft 63 close to the telescopic sleeve 61 is slidably connected to the inner side of the telescopic sleeve 61 and can also rotate on the inner side of the telescopic sleeve 61. The setting of the spirit level 62 can effectively determine the horizontal position of the supporting plate 6 to ensure that it is completely horizontal. The pull ring 7 can drive the connecting rod 75 to rotate, thereby driving the mounting block 8 to drive the rotating shaft 63 to rotate, which is convenient for fine-tuning the angle of the supporting plate 6.

[0047] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the clamping assembly includes a movable clamping plate 11, a fixed clamping plate 12 and a hydraulic push rod 13. The fixed clamping plate 12 and the hydraulic push rod 13 are both fixedly connected to the top of the placement platform 1. The output end of the hydraulic push rod 13 is fixedly connected to the movable clamping plate 11, and the movable clamping plate 11 is slidably connected to the top of the placement platform 1.

[0048] Therefore, the hydraulic push rod 13 can effectively drive the movable clamping plate 11 to move, so as to fix the laser rangefinder between the movable clamping plate 11 and the fixed clamping plate 12 .

[0049] like Figure 3 As shown, in the present disclosure, the mounting block 8 is arranged on the inner side of the fixed clamping plate 12, and a limiting groove 81 is arranged on the inner side of the mounting block 8. The end of the connecting ring 72 is fixedly connected with a sliding rod 73, and the sliding rod 73 is slidably connected to the inner side of the mounting block 8. The two ends of the outer side of the sliding rod 73 are symmetrically fixedly connected to the limiting blocks 74, and the limiting blocks 74 are slidably arranged on the inner side of the limiting groove 81.

[0050] As a result, the pull ring 7 and the connecting rod 75 are fixed to each other, the connecting rod 75 and the connecting ring 72 are fixed to each other, the connecting ring 72 and the sliding rod 73 are fixed to each other, and the limit block 74 and the sliding rod 73 are fixed to each other, so that pulling the pull ring 7 can drive the connecting rod 75, the positioning block 71, the sliding rod 73 and the limit block 74 to move, and rotating the pull ring 7 can drive the sliding rod 73 and the limit block 74 to rotate, and the limit block 74 is limited on the inner side of the limit groove 81. Rotating the sliding rod 73 drives the limit block 74 to rotate and can also drive the mounting block 8 to rotate. The mounting block 8 is fixedly connected to the rotating shaft 63, thereby driving the rotating shaft 63 and ultimately driving the supporting plate 6 to rotate.

[0051] like Figure 3 As shown, in a preferred embodiment, a spring 76 is disposed on the outer side of the connecting rod 75 , and a blocking block 121 is disposed on the inner side of the fixed clamping plate 12 .

[0052] Therefore, the spring 76 is arranged on one side of the connecting ring 72, which can effectively press the connecting ring 72 to the outside of the mounting block 8, that is, effectively limit the pull ring 7 to the outside of the fixed clamping plate 12. By setting the blocking block 121, the movement of the connecting ring 72 can be effectively limited, so that the movement of the connecting ring 72 cannot cause the limiting block 74 to slide out from the inner side of the limiting groove 81.

[0053] like Figure 3 As shown, in the present disclosure, a positioning block 71 is fixedly connected to one side of the pull ring 7 close to the fixed clamping plate 12 , a plurality of positioning grooves 122 are evenly arranged on the inner side of the fixed clamping plate 12 , and the positioning block 71 is arranged on the inner side of the positioning groove 122 .

[0054] Therefore, pulling the pull ring 7 can slide the positioning block 71 out from the inner side of the positioning groove 122, so that the pull ring 7 can be rotated. There are multiple positioning grooves 122 evenly arranged, so that the positioning block 71 can be set on the inner side of the positioning groove 122 according to selection, so as to ensure the horizontal setting of the supporting plate 6.

[0055] like Figure 1 As shown, in the present disclosure, the lifting assembly includes a vertical rod 2 and an extension rod 3. The vertical rod 2 is fixedly connected to the top of the chassis 21, and the extension rod 3 is slidably connected to the inner side of the vertical rod 2. A latch 4 is provided on the outer side of the vertical rod 2, and a plurality of limiting holes 31 are evenly provided on the inner side of the extension rod 3. The latch 4 passes through the vertical rod 2 and is provided on the inner side of the limiting hole 31.

[0056] Therefore, the pin 4 is pulled out from the inner side of the vertical rod 2, and the height of the extension rod 3 can be selected according to the actual use height. The extension rod 3 is slid out from the inner side of the vertical rod 2 to drive the placement platform 1 to move. After the height of the placement platform 1 is selected, the pin 4 is inserted into the inner side of the vertical rod 2 and the inner side of the limit hole 31 is set to limit the extension rod 3.

[0057] like Figure 2 As shown, in the present disclosure, the rotating assembly includes a rotating block 32 and a fixed block 14, the fixed block 14 is fixedly connected to the bottom end of the placement platform 1, the rotating block 32 is fixedly connected to the top end of the extension rod 3 and is rotatably arranged on the inner side of the fixed block 14, and a bolt 5 is arranged on the outer side of the fixed block 14, and the bolt 5 is threadedly connected to the inner side of the fixed block 14.

[0058] Therefore, when adjusting the angle of the laser rangefinder, the bolt 5 is unscrewed from the inner side of the fixed block 14, and the angle of the placement platform 1 is adjusted. After the angle is determined, the bolt 5 is tightened to the inner side of the fixed block 14, and the rotating block 32 is pressed so that the rotating block 32 is limited to the inner side of the fixed block 14, thereby effectively determining the position of the placement platform 1.

[0059] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.
