Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
Embodiment：A kind of simple ranging rod, as shown in Figure 1, including support frame 1, length direction sliding in support frame 1
It is connected with ruler 2 with a scale, the side of 1 length direction of support frame is provided with for demarcating 2 horizontal distance of gauger and ruler
Calibration element 3, calibration element 3 is vertical with support frame 1.
As shown in Fig. 2, need to measure some determinand to gauger apart from when, selected known to one around determinand
The object of reference (if determinand height is it is known that can also be determinand) of height, it is good that gauger faces object of reference station, holds with a hand
Support frame 1, and level stretches arm, support frame 1 is in vertical parastate with gauger at this time, by the ruler 2 in support frame 1
It pushes up, and the eyes on the top of ruler 2, the top of object of reference and gauger is made to be in same straight line.2 top of ruler is read to arrive
The vertical range of calibration element 3, according to the proportional principle of similar triangles corresponding sides, so that it may to calculate gauger to tested mesh
Target distance.
As shown in Fig. 2, according to above-mentioned principle, the distance of eyes to ruler 2 is AB, and the distance between 2 points of EF is object of reference
Height, BC be ruler 2 rise height, then the distance of people to object of reference can be released from following algorithm：Triangle CAB and three
Angular FAE is similar triangles, can obtain AE/AB=EF/BC.Then AE=AB*EF/BC, wherein AB, EF, BC simple can be obtained
Arrive, thus can read or calculate people to object of reference distance.
As shown in figure 3, the side of ruler 2 is provided with the first graduation mark 21 along length direction, the first graduation mark 21 is used
In indicating 2 top of ruler to the distance on 1 top of support frame, support frame 1 is close to the side of the first graduation mark 21 along length side
To the second graduation mark 22 is provided with, it is divided into 0.6mm between the first graduation mark 21,1.14mm is divided between the second graduation mark 22.Root
According to the principle of vernier caliper, gauger can intuitively obtain ruler 2 from the cooperation of the first graduation mark 21 and the second graduation mark 22
The length that ruler 2 stretches out can be accurate to one decimal place, improve measurement accuracy by the height of stretching.
As shown in figure 3, ruler 2 is provided with third graduation mark away from the side of the first graduation mark 21 along length direction
23, the distance that third graduation mark 23 is used to indicate gauger to determinand, the numerical value of third graduation mark 23 is with determinand height
On the basis of 10m.If the height of determinand is not 10m, acquired using formula L=KI, in formula：L- gaugers are to determinand
Distance；The distance read on I- thirds graduation mark 23；The ratio of K- determinand known altitude T (m) and 10m, K=T/10.In this way
Can quickly calculate gauger to determinand distance.
As shown in Figure 1, offering waist type groove 11 along length direction among support frame 1, support frame 1 is provided with and ruler
The end of the 2 lifting stop screws 12 being threadedly coupled, lifting stop screw 12 is against the slot bottom of waist type groove 11.Ruler 2 is stretched out
To after the position conllinear with determinand top, lifting stop screw 12 is screwed, ruler 2 and support frame 1 are just in relatively-stationary
State avoids ruler 2 from moving.
As shown in Figure 1, the lower end of ruler 2 is provided with anti-skid chequer 13.Gauger is by pushing portion of the ruler 2 with anti-skid chequer 13
Position avoids thumb from being slided with respect to ruler 2, causes 2 accurate movement of ruler.
As shown in Figure 1, calibration element 3 include with 1 fixed fixed block 31 of support frame, be hinged with a calibration on fixed block 31
Bar 32, the outside vertical of fixed block 31 are provided with the limiting plate 33 of fitting 31 lateral wall of fixed block, 90 ° are offered on limiting plate 33
Arc groove 34, fixed block 31 be provided through arc groove 34 and be threadedly coupled with demarcate bar 32 Horizontal limiting screw 35 (ginseng
According to Fig. 4).The end of demarcate bar 32 is against below eyes by gauger, and eyes and support frame 1 is made to be substantially at same horizontal line,
The distance of support frame 1 and eyes is length when demarcate bar 32 moves limit position at this time, the length of demarcate bar 32 fix it is known that
Reduce a measured value, improves measurement efficiency.
After demarcate bar 32 to be turned to the position vertical with support frame 1, Horizontal limiting screw 35 is screwed, you can keep support
Frame 1 and demarcate bar 32 are relatively fixed, and are avoided demarcate bar 32 from sliding, are influenced normally to measure.When need not use ranging rod, it will mark
Fixed pole 32 turns to the position parallel with support frame 1, reduces the space that ranging rod occupies, is convenient for carrying.
As shown in Figure 1, demarcate bar 32 is scalable, 32 longest distance of demarcate bar is 600mm in the present invention, in specific practicality simultaneously
It is not limited only to 600mm, can be the length arbitrarily determined.Demarcate bar 32 can also can quickly be contracted with rapid elongation to fixed value
It is short, it is further reduced the space that ranging rod occupies when not used.
The course of work：The selected determinand for needing to measure of gauger, finds the height of determinand, and face determinand station
It is good.Horizontal limiting screw 35 is unscrewed, and demarcate bar 32 is turned to the position vertical with support frame 1, then screws Horizontal limiting spiral shell
Nail 35.
Lifting stop screw 12 is unclamped, pulls long demarcate bar 32 to maximum with another, gauger, which will stretch out left arm, to demarcate
Bar 32 is placed in level orientation, and the end of demarcate bar 32 is against below eyes, eyes and 1 upper surface of support frame is made to be substantially at together
One horizontal line, the distance of support frame 1 and eyes is the length of demarcate bar 32 at this time.Gauger hopes to determinand, according to anti-skidding
Line 13 pushes up ruler 2, after the point of observation three point on a straight line on the top of ruler 2, the top of determinand and gauger, uses the right hand
Screw lifting stop screw 12, according to the numerical value and vernier groove on ruler 2, read or calculate determinand to gauger away from
From.
