And level board is stretched out in the front and back end of pin shaft, the front and back end of the pin shaft is equipped with protractor, and the origin of protractor is located at pin
On the axis of axis, the baseline of the protractor and the lower end surface of bottom plate are parallel, and the front and back end of level board is equipped with horizontal finger
For the axis of timberline, the index line and pin shaft in same level, the upper end of the level board is equipped with the level of left and right settings
Ruler.
Preferably, the upper end of the bottom plate is hingedly connected with guide cylinder, and the other end of guide cylinder is plugged with telescopic rod, institute
The upper end of the other end and level board of stating telescopic rod is articulated and connected, and the end face that guide cylinder is contacted with telescopic rod is equipped with non-slip rubber
Layer.
Preferably, limit drawstring is equipped between the left end of the telescopic rod and the inner cavity left end of guide cylinder.
Preferably, the front end of the guide cylinder is equipped with tightening knob.
Preferably, the lower end of the bottom plate is uniformly provided with anti-skidding sawtooth.
The utility model proposes a kind of road grade measuring device, beneficial effect is: in use, bottom plate is against flat
In whole road slope surface, anti-skidding sawtooth then increases resistance, prevents bottom plate from gliding, and then left hand presses bottom plate, right hand rotation water
Plate when close to horizontal position, observes horizontal ruler, and level board is adjusted to horizontal, and guide cylinder, telescopic rod and anti-by horizontal ruler
The setting of sliding rubber layer, then guarantee that level board will not arbitrarily shake, can thus pass through the scale of index line face protractor
Line finds out angle, simple and convenient without calculating, and measurement also facilitates, more efficient.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of road grade measuring device structural schematic diagram；
Fig. 2 be the utility model proposes a kind of road grade measuring device main view.
In figure: 1 level board, 2 pin shafts, 3 bottom plates, 4 protractors, 5 index lines, 6 horizontal rulers, 7 guide cylinders, 8 telescopic rods, 9 are prevented
Sliding rubber layer, 10 limit drawstrings, 11 tightening knobs, 12 anti-skidding sawtooth.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of road grade measuring device, including level board 1, the left end of level board 1 offers to be passed through up and down
The installing port worn, and the bottom plate 3 that left end is upturned is rotatably connected to by pin shaft 2 at installing port, the lower end of bottom plate 3 is uniformly set
There is anti-skidding sawtooth 12, prevents bottom plate 2 from sliding, pin shaft 2 is fixedly connected with bottom plate 3, and level board 1 is stretched out in the front and back end of pin shaft 2,
The front and back end of pin shaft 2 is equipped with protractor 4, and the origin of protractor 4 is located on the axis of pin shaft 2, the baseline of protractor 4 and bottom
