Specific embodiment
Below in conjunction with schematic diagram to the utility model proposes road grade measuring device be described in more detail,
In illustrate the preferred embodiment of the utility model, it should be appreciated that those skilled in the art can modify described herein it is practical
It is novel, and still realize the advantageous effects of the utility model.Therefore, following description should be understood as those skilled in the art
Member's is widely known, and is not intended as limitations of the present invention.
As shown in Figure 1, the measuring device includes 1 He of shell the utility model proposes a kind of road grade measuring device
Connected power module 6 and measurement module 7 in shell 1 is set.Shell 1 is Contraband shape, and there is upper and lower two forward horizontals to prolong
The hand-held part of the first measurement end and the second measurement end and vertical the first measurement end of connection and the second measurement end stretched.It is hand-held
Portion is equipped with control button 8, and control button 8 and measurement module 7 connect, and control button 8 includes power on button, measurement button and shutdown
Button.Measurement module 7 includes that first laser transmitter 2, first laser receiver 3, first laser transmitter 4 and second laser connect
Receive device 5；First laser transmitter 2 and first laser receiver 3 are mounted in the first measurement end；First laser transmitter 4 and
