[0022] The utility model provides a quick centering device for a level or theodolite, such as Figure 1-Figure 5 As shown, it comprises: a first chuck 1, a centering slide plate 2, a second chuck 3, a first locking portion 4 and a second locking portion 5. A centering slide plate 2 is provided between the first chuck 1 and the second chuck 3. The first chuck 1 and the second chuck 3 are coaxially arranged. The centering slide plate 2 can slide in the transverse and longitudinal directions respectively to achieve centering. The first locking portion 4 locks the centering slide plate 2 in the transverse direction. The first locking portion 4 is arranged on the lower surface of the first chuck 1. The second locking portion 5 locks the centering slide plate 2 in the longitudinal direction. The second locking portion 5 is arranged on the upper surface of the second chuck 3. Rapid centering and locking are achieved by sliding the centering slide plate 2. The rapid centering device is easy to install and disassemble, and there is no need to modify and adjust the instrument 7 and the tripod, so the purpose of rapid and accurate centering of the instrument 7 can be achieved.

[0023] In the level or theodolite quick centering device provided by the utility model, as Figure 2 and Figure 3 As shown, the first locking part 4 includes a first fixed block 41, a first adjustable slider 42 and a first tightening hand wheel 43. The first fixed block 41 and the first adjustable slider 42 are symmetrically arranged on the lower surface of the first chuck 1 perpendicular to the transverse direction. The first fixed block 41 and the first adjustable slider 42 are symmetrically arranged about the center position of the first chuck 1. Two first limit blocks 21 arranged parallel to the first fixed block 41 are arranged on the upper surface of the centering slide plate 2. The first limit blocks 21 are respectively aligned with the first fixed block 41 and the first adjustable slider 42. The first tightening hand wheel 43 tightens and fixes the first adjustable slider 42. The first tightening hand wheel 43 is arranged on the first chuck 1. The first fixed block 41 and the first adjustable slider 42 are connected and arranged on the lower surface of the first chuck 1 by screws. When the first adjustable slider 42 is installed, an adjustable gap is left between the screw and the first adjustable slider 42, and then tightened by the first tightening hand wheel 43 to achieve rapid centering.

[0024] Furthermore, in the rapid centering device for the level or theodolite provided by the utility model, the cross sections of the first fixed block 41, the first adjustable slider 42 and the first limit block 21 are all right-angled trapezoidal structures, the inclined surface of the first fixed block 41 fits with the inclined surface of the first limit block 21, and the inclined surface of the first adjustable slider 42 fits with the inclined surface of another first limit block 21. When the sliding centering slide plate 2 is slid, the first fixed block 41 fits with the first limit block 21 to achieve positioning, and then the first adjustable slider 42 is fixed by tightening the first tightening hand wheel 43, and rapid centering and fixing is achieved in the lateral direction through the fit of the inclined surfaces. Specifically, the two first limit blocks 21 are symmetrically fixed about the center position of the centering slide 2, and the distance between the first fixed block 41 and the first adjustable slider 42 is slightly larger than the distance between the two first limit blocks 21 on the centering slide 2. When the centering slide 2 is slid, since a gap is left when the first adjustable slider 42 is installed, quick centering can be achieved by tightening the first tightening hand wheel 43 so that the inclined surface of the first adjustable slider 42 fits and is fixed to the inclined surface of the first limit block 21.

[0025] In addition, in the level or theodolite quick centering device provided by the utility model, Figure 3 and Figure 4As shown, the second locking part 5 includes a second fixed block 51, a second adjustable slider 52, and a second tightening hand wheel 53. The second fixed block 51 and the second adjustable slider 52 are symmetrically arranged on the upper surface of the second chuck 3 in parallel with the transverse direction. The second fixed block 51 and the second adjustable slider 52 are symmetrically arranged about the center position of the second chuck 3. The lower surface of the centering slide plate 2 is provided with two second limit blocks 22 arranged in parallel with the second fixed block 51. The second limit blocks 22 are respectively aligned with the second fixed block 51 and the second adjustable slider 52 and tightened by the second tightening hand wheel 53. The second tightening hand wheel 53 is arranged on the second chuck 3. The second fixed block 51 and the second adjustable slider 52 are installed on the upper surface of the second chuck 3 by screws. When the second adjustable slider 52 is installed, an adjustable gap is left between the screws and the second adjustable slider 52, and then tightened by the second tightening hand wheel 53 to achieve rapid centering. Specifically, two first limit blocks 21 are provided on the upper surface of the centering slide 2, and two second limit blocks 22 are provided on the lower surface of the centering slide 2. The two first limit blocks 21 and the two second limit blocks 22 form an overall square structure, so that centering can be achieved in both the transverse direction and the longitudinal direction, and then fixed by the first tightening hand wheel 43 and the second tightening hand wheel 53 respectively, so as to achieve the purpose of rapid centering.

[0026] In the level or theodolite quick centering device provided by the utility model, the cross-sections of the second fixed block 51, the second adjustable slider 52 and the second limit block 22 are all right-angled trapezoidal structures, the inclined surface of the second fixed block 51 fits with the inclined surface of the second limit block 22, and the inclined surface of the second adjustable slider 52 fits with the inclined surface of the other second limit block 22. Figure 5 As shown. When the sliding centering disk 2 is slid, the second fixed block 51 is fitted with the second limit block 22 to achieve positioning, and then the second adjustable slider 52 is fixed by tightening the second tightening hand wheel 53, and the fast centering and fixing is achieved in the direction perpendicular to the transverse direction (i.e., the longitudinal direction) by the fitting of the inclined surface. The distance between the second fixed block 51 and the second adjustable slider 52 is slightly larger than the distance between the two second limit blocks 22 on the centering disk 2. When the sliding centering disk 2 is slid, since the second adjustable slider 52 is installed with a gap, the inclined surface of the second adjustable slider 52 can be fitted and fixed with the inclined surface of the second limit block 22 by tightening the second tightening hand wheel 53 to achieve fast centering.

[0027] Furthermore, in the level or theodolite quick centering device provided by the utility model, the center positions of the first chuck 1, the centering slide plate 2, and the second chuck 3 are all hollow disc structures, and the centers are all threaded holes for installing the hollow stud 6. The first chuck 1 and the second chuck 3 are connected by the hollow stud 6, the first chuck 1 and the instrument 7 are tightened and fixed by the hollow stud 6, and the second chuck 3 and the tripod 8 are fixed by the buckle 9 to achieve the fixation of the instrument 7 and the tripod 8. The instrument 7 can be a level or a theodolite.
