Embodiment
With reference to Figure of description and embodiment, specific embodiment of the present utility model is made further to retouch in detail
State.Following examples are merely to illustrate the utility model, but can not be used for limiting the scope of the utility model.
Referring to shown in Fig. 1-4, the centering rod spirit level calibration device of the utility model embodiment, including rubber sleeve（In figure
It is not shown）With two pieces of fixation steel plates 2 being respectively welded on angle steel 1；Centering rod 3 is fixed on angle steel 1 by rubber sleeve；Two pieces solid
Determine that steel plate 2 is fixed on wall 5 and angle steel 1 is being vertically arranged in horizontal direction.
In certain embodiments, the size that two pieces of fixation steel plates 2 use is 90mm*60mm*3mm, by two pieces of fixation steel plates 2
Weld together with angle steel 1, and slotted eye 6 is milled out in the certain position of fixation steel plate 2.Wherein, the length in the horizontal direction of slotted eye 6
Degree than in the long of vertical direction, being so easy to adjust in the horizontal direction, with ensure angle steel 1 in horizontal direction vertically
Set.
Further, when selecting angle steel 1, it is necessary to check whether that the edge size of angle steel side 1 can not be more than 30mm, side straight
Edge size is necessarily less than centering shank diameter, when centering rod is put into 1 inner side of angle steel, ensures that centering rod 3 protrudes, facilitates the use rubber
