Detailed Description
As shown in fig. 2, the invention comprises a base 1, a vertical rod 2 and a cross rod 3, wherein the vertical rod 2 is vertical to the base, the lower end of the vertical rod is fixedly connected with the base 1, one end of the cross rod 3 is rotatably connected with the vertical rod through a cross rod fastening clamp 5 and can be fixed with the vertical rod through the cross rod fastening clamp; 3 leveling screw rods 6 vertically penetrating through the base are arranged on the base 1 at equal intervals in the circumferential direction, and leveling air bubbles 7 are arranged on the top surface of the base; the cross rod 3 is perpendicular to the vertical rod 2, and the angle adjusting device of the deflection measuring instrument is sleeved on the cross rod 3.
The structure of the deflection measuring instrument angle adjusting device is shown in fig. 3, and the deflection measuring instrument angle adjusting device comprises a sleeve 8, one end of the sleeve 8 is connected with an annular disk sleeve 10 through a plurality of connecting rods 9 which are radially arranged, an annular angle scale 11 is arranged in the disk sleeve 10, the angle scale 11 is coaxial with the disk sleeve 10, and the diameter of the angle scale 11 is smaller than that of the disk sleeve 10. One side of the sleeve 8 is provided with a fastening bolt 12 penetrating through the wall of the sleeve, and the other side of the sleeve opposite to the fastening bolt is provided with a deflection measuring instrument fixing clamp 13.
The inner diameter of the sleeve 8 is larger than the diameter of the cross rod, the sleeve 8 is movably sleeved on the cross rod 3 and can be fixed with the cross rod through a fastening bolt 12. The angle scale 11 is sleeved on the cross rod 3, as shown in fig. 2 and 4, a plurality of sliding grooves 31 are longitudinally arranged on the cross rod 3, as shown in fig. 5, limiting blocks 111 corresponding to the sliding grooves 31 on the cross rod are arranged on the inner ring of the angle scale 11, and each limiting block 111 on the angle scale is clamped into one sliding groove 31 on the cross rod. An angle scale 112 is annularly arranged on the angle scale 11 near the outer ring edge, and a pointer 14 pointing to the angle scale on the angle scale is arranged on the disk sleeve 10.
According to the structure, the sleeve 8 and the disc sleeve 10 of the deflection measuring instrument angle adjusting device can rotate and slide around the cross rod 3, and the angle disc 11 can longitudinally slide along the cross rod but cannot rotate around the cross rod under the limitation of the limiting block. When the sleeve 8 and the sleeve 10 rotate, the angle scale 11 is not moved, so that the pointer 14 on the sleeve can indicate the rotation angle of the sleeve.
When the invention is used, the deflection measuring instrument is fixedly arranged on the deflection measuring instrument fixing clamp 13 on the sleeve. The base 1 can be adjusted to be in a horizontal state through the leveling screw 6. According to the included angle between the measured surface and the horizontal plane, calculating the inclination angle which enables the deflection measuring instrument to be vertical to the measured side surface, loosening the fastening bolt 12 on the sleeve, rotating the sleeve 8, enabling the deflection measuring instrument to rotate along with the sleeve, rotating the sleeve to a preset angle according to the reading of the pointer 14 on the disk sleeve, and then fixing the sleeve 8 and the cross rod 3 through the fastening bolt, thereby accurately adjusting the angle of the deflection measuring instrument.
