Detailed Description

The utility model is described in detail below with reference to the attached drawings:

as shown in fig. 1 and 2, a laser scanning level calibration support, including base 1, specifically, base 1 includes a plurality of support bars 101, set up three support bar 101 in this embodiment, the tip of three support bar 101 adopts welded mode fixed connection, constitute the chevron shape structure, three support 101 strip is located the coplanar, be fixed with on base 1 with base 1 be mutually perpendicular clamping strip 2 that sets up, specifically, clamping strip 2 sets up in the junction of three support 101, clamping strip 2's cross section is the rectangle, clamping strip 2 is used for the centre gripping scale, be equipped with draw-in groove 3 along clamping strip 2 length direction on the clamping strip 2, can place the scale in draw-in groove 3 during the use, the lateral wall of draw-in groove 3 is equipped with a plurality of centre gripping screw 4 along draw-in groove 3 length direction, be equipped with centre gripping bolt 5 in the centre gripping screw 4, can screw 5 with the scale after placing in draw-in groove 3, still be equipped with bi-directional level meter 6 and be used for adjusting base 1 horizontally adjusting member 7 on base 1 through centre gripping bolt 5, bi-directional level meter 6 installs in arbitrary one and is equipped with the screw 6, can be in base 1 is in the base 1 is adjusted to the base is in the condition of adjusting member 702, can be adjusted to the base 1, be equipped with the base is in the condition of adjusting member 702, the base is adjusted to be in the condition is adjusted to be in the base 1 is 702, the base is adjusted to be in the condition is adjusted, and is 702 is adjusted.
