Detailed description of the invention
A kind of scissor-shaped enlarged footing anchor hole inside caliper present invention provided below in conjunction with specific embodiment
It is further described.
A kind of scissor-shaped enlarged footing anchor hole inside caliper, as shown in Figure 1, including being symmetricly set in montant 1
Bar 3 measured by first measurement bar 2 and second of both sides, and described first measurement bar 2, second is measured bar 3, erected
The middle part of bar 1 is hinged by cutting axle 4, described first measure bar 2, second measure the upper end of bar 3 respectively with stretch
The two ends of contracting bar 5 connect, and the body of rod of described expansion link 5 is arranged with the first sleeve 6, described first sleeve 6
Be connected with the upper end of montant 1, described second measure bar 3 lower end be connected with shrinkage-rule 7 one end, described in stretch
Reduced scale 7 other end is scalable to be plugged in the second sleeve 8, and bar 2 measured by described second sleeve 8 and first
Lower end connects, and the lower end of described montant 1 is connected with shrinkage-rule 7.
As shown in Figure 2, offer in the middle part of described montant 1 for cut axle 4 along montant 1 body of rod direction come and go fortune
Dynamic stopper slot 9.Montant 1 and the relative motion cut between axle 4 are played position-limiting action by stopper slot 9.Described
Montant 1 is the scalable body of rod.When montant 1 is to cut that centered by axle 4, axle radially moves, drive shrinkage-rule
Elongation, so that the first measurement bar 2 and the second measurement bar 3 open therewith.
Further, the described first upper end measuring bar 2 and the second measurement bar 3 is mounted on measurement 10.
Measure when head is fully contacted with anchor hole wall and can get anchor hole diameter.
Offering through hole on described shrinkage-rule 7, described montant 1 is connected through described through hole with shrinkage-rule 7.
It is provided with scale groove, when this scale and the first measurement bar 2 and the second measurement bar 3 open on described shrinkage-rule 7
Distance between two measurements 10 is corresponding.
Gripping for convenience, the lower end of described montant 1 is provided with handle 11.
Described first measures bar 2 and second, and to measure bar 3 length equal, described in cut axle 4 and be arranged at the first measurement
Bar 2 and the midpoint of the second measurement bar 3.
The present invention is achieved in that when measuring anchor hole internal diameter, measuring device is measured first end and stretches into anchor
In hole, stretch-draw handle 11, make montant 1 do radial motion for axle center to cut axle 4, montant 1 drives shrinkage-rule 7
Elongation is stretched out from the second sleeve 8, so that the first measurement bar 2 and the second measurement bar 3 open, expansion link 5
Extending the most therewith, when two measurements 10 touch hole wall, montant 1 moves stopping, by measuring device along anchor
The same depth location in hole rotates a circle, to determine whether two measurements 10 are stuck in maximum gauge position, really
After recognizing, we can read a numerical value on shrinkage-rule 7, and the scale and first on shrinkage-rule 7 measures bar
2 and second measure bar 3 when opening two distances measured between 10 corresponding, such that it is able to directly read
The size of anchor hole diameter.Further, the most also can measure bar 2 and second according to first and measure bar 3
The angle opened, draws the hole depth that this anchor hole diameter maximum is corresponding.
It is understood that for the person of ordinary skill of the art, can be according to the technology structure of the present invention
Think to make other various corresponding changes and deformation, and all these change all should belong to right of the present invention with deformation
The protection domain required.
