[0032] Please refer to Figures 1 - 7 , the present utility model provides a measuring device, including a distance measuring device 100, a plug rod 200 and a limiting device 300.

[0033] The distance measuring device 100 includes a control box 110. A laser rangefinder 111 for distance measurement is installed at the upper end of the control box 110. A support block 120 is fixedly installed at the lower end of the control box 110. A plurality of reinforcing ribs 121 are fixedly installed at the upper end of the support block 120. A fixing block 122 is fixedly installed at the lower end of the support block 120, and the fixing block 122 rotates within the cavity of the limiting groove 312, facilitating the rotational adjustment of the laser rangefinder 111.

[0034] A limiting device 300 for supporting the distance measuring device 100 is installed at the lower end of the distance measuring device 100. The limiting device 300 includes a limiting sleeve 310. The limiting sleeve 310 includes a cylinder body 311. A limiting groove 312 for the fixing block 122 to rotate is opened at the upper end of the cylinder body 311. A cavity for accommodating the plug rod 200 is opened inside the cylinder body 311.

[0035] A plug rod 200 for stabilizing the limiting device 300 is installed at the lower end of the limiting device 300, and the plug rod 200 can be telescoped inside the cylinder body 311. A spiral groove 210 is opened at the upper end of the plug rod 200. When the slider on the inner wall of the lead screw nut 331 slides on the cavity of the spiral groove 210, the plug rod 200 is simultaneously driven to telescope inside the cylinder body 311, enabling the operator to accommodate the plug rod 200 when distance measurement is not required.

[0036] A plurality of movable rods 220 for stabilizing the plug rod 200 are installed at the lower end of the plug rod 200. The lower end of the plug rod 200 is inserted into the soil, and the movable rods 220 are in contact with the ground, making the plug rod 200 stable on the ground and not prone to deviation and shaking, ensuring the measurement accuracy. A plurality of receiving grooves 230 for accommodating the movable rods 220 are opened at the lower end of the plug rod 200.

[0037] A spring 313 is sleeved in the middle of the cylinder body 311, and the lower end of the spring 313 abuts against the upper end of the locking assembly 320. An annular fixing block 314 for limiting the spring 313 is fixedly installed in the middle of the cylinder body 311. A plurality of L-shaped sliding grooves 315 for limiting the locking assembly 320 are machined on the outer wall of the lower end of the cylinder body 311, and the slider 323 slides within the cavity of the L-shaped sliding groove 315. The L-shaped sliding groove 315 includes a horizontal groove and a vertical groove.

[0038] A locking component 320 for locking the height adjustment component 330 is installed at the lower end of the limit sleeve 310. The locking component 320 includes an annular block 321. A plurality of insertion blocks 322 are fixedly installed at the lower end of the annular block 321. A plurality of sliding blocks 323 for sliding in the cavity of the L-shaped sliding groove 315 are fixedly installed on the inner wall of the annular block 321.

[0039] When the sliding block 323 slides into the horizontal groove, the locking component 320 is locked, so that the annular block 321 moves away from the height adjustment component 330, and the insertion block 322 moves away from the cavity of the insertion slot 332. When the sliding block 323 is in the vertical groove, the spring 313 pushes the annular block 321, driving the insertion block 322 to be inserted into the cavity of the insertion slot 332, thereby locking the lead screw nut 331, making the lead screw nut 331 unable to rotate, and further locking the height of the insertion rod 200.

[0040] A height adjustment component 330 for cooperating with the spiral groove 210 to control the up and down movement of the insertion rod 200 is movably installed at the lower end of the limit sleeve 310. The height adjustment component 330 includes a lead screw nut 331. A plurality of insertion slots 332 for cooperating with the insertion block 322 to lock the lead screw nut 331 are formed at the upper end of the lead screw nut 331.

[0041] During detection, the locking component 320 is moved upward and rotated, so that the sliding block 323 moves to the horizontal groove of the L-shaped sliding groove 315, and the lead screw nut 331 is rotated. The lead screw nut 331 cooperates with the spiral groove 210 to control the insertion rod 200 to move downward, thereby adjusting the height of the laser rangefinder 111 according to the heights of different operators. By rotating the locking component 320 in the reverse direction, the sliding block 323 is moved to the vertical groove of the L-shaped sliding groove 315, and the spring 313 pushes the annular block 321 downward, so that the insertion block 322 is inserted into the cavity of the insertion slot 332, thereby locking the limit sleeve 310, making the limit sleeve 310 unable to rotate, and further locking the height of the laser rangefinder 111.

[0042] Although the present invention has been described in detail above with general descriptions and specific embodiments, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
