Description
Technical field
A kind of survey tool is the utility model is related to, more specifically, it relates to a kind of pitch-row vernier caliper.
Background technology
Slide measure is a kind of measurement length, internal-and external diameter, the measurer of depth.Slide measure is by main scale and is attached to energy on main scale
Vernier two parts of slip are formed.Have two secondary movable measuring claws on the main scale and vernier of slide measure, be respectively internal measure-hand and
Exterior measuring measuring jaw, internal measure-hand are works commonly used to measurement length and external diameter, slide measure commonly used to measurement internal diameter, exterior measuring measuring jaw
The instrument for the measurement length commonly used in industry.
Existing Authorization Notice No. provides a kind of Multifunctional pitch-row vernier caliper for CN202229686U Chinese patent, bag
Blade is included, is slid on blade and is provided with vernier, two pitch-row measuring claws are provided with blade, its pitch-row measuring claw section is axial symmetry
Del；In use, pitch-row measuring claw is deep into hole, because inside diameter measurement pawl is in symmetry, pitch-row measuring claw is just
The hole heart is navigated to, so as to measure the centre-to-centre spacing of holes.
But when measuring the centre-to-centre spacing of holes using the pitch-row vernier calliper, it is necessary to ensure that the axis of blade and holes is equal
Vertically, make projection line of the axis in hole on measuring claw conllinear with the center line in measuring claw section, can just measure the center of holes
Away from；When needing to measure the centre-to-centre spacing of the holes at different height, because two measuring claws need to be deep into different height
In the hole at place, blade just can not be vertical with the axis of holes, leads to not the centre-to-centre spacing for measuring holes.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of pitch-row vernier caliper, it has
There is the advantage for the centre-to-centre spacing that can measure the holes positioned at different height.
To achieve the above object, the utility model provides following technical scheme：
A kind of pitch-row vernier caliper, including main scale and the first zero graduation line positioned at main scale one end, slide on the main scale
Vernier is provided with, described vernier one end is provided with the second zero graduation line, and it is in isosceles triangle that described main scale one end, which is provided with section,
The first measuring claw, be provided with the second measuring claw that section is in isosceles triangle on the vernier, first measuring claw etc.
The center line of lumbar triangle tee section is conllinear with the first zero graduation line, the center line of the isoceles triangle tee section of second measuring claw and
Two zero graduation lines are conllinear, and width of first measuring claw along main scale connects with main scale sliding.
By using above-mentioned technical proposal, when needing to measure the centre-to-centre spacing of the holes at different height, keeping
On the premise of the axis of main scale and holes is vertical, the first measuring claw is slided to the direction in hole, the first measuring claw is extend into phase
To in the relatively low hole in position；Then moving cursor, the second measuring claw is deep into the higher hole of relative position, and with the inwall in hole
Offset, on the premise of continuing to ensure main scale perpendicular to the axis of holes, adjust the position of the first measuring claw, make the first measurement
The inwall of pawl, the second measuring claw respectively with two holes offsets, and reading simultaneously is completed to measure, and realizes measurement at different height
The purpose of the pitch-row of holes.

By using above-mentioned technical proposal, trapeze bar slides in main scale with respect to the back side of vernier, so as to not influence in front
Vernier sliding, make the sliding of the second measuring claw unrestricted；By setting dovetail groove and trapeze bar, sliding trapeze bar
The bottom wall of dovetail groove can be fitted in journey, makes slip more steady.
Further, first measuring claw can be provided with the main scale place of fitting for the first measuring claw to be adsorbed in master
Flat thin magnet on chi.
By using above-mentioned technical proposal, during slide measure of taking, the first measuring claw slides on main scale, and first
Pointed part on measuring claw easily can adsorb the first measuring claw in main scale into accidental injury, flat thin magnet to artificial in sliding
On, so that the first measuring claw does not slide when not in use.
Further, the trapeze bar is provided with the limited block that can be offseted with main scale away from first measuring claw one end.
By using above-mentioned technical proposal, limited block can make trapeze bar will not be skidded off along dovetail groove slipping it is trapezoidal
Groove, so that measuring jaw can slide in the length range of trapeze bar and not depart from main scale.
Further, the limited block lateral wall is provided with fixing hole, and the fixing hole madial wall is provided with fastener, institute
State trapeze bar lateral wall and be provided with the buckle slot being interlocked with fastener.
By using above-mentioned technical proposal, limited block can be interlocked by fastener and buckle slot, so as to realize and ladder
Shape bar is detachably connected；After limited block is removed, trapeze bar and the first measuring claw can be removed from main scale, be accounted for so as to reduce
With space, it is easy to store.Meanwhile it is conveniently replaceable various sizes of first measuring claw.
Further, center line of the first measuring claw lateral wall along its section triangle is provided with positive stop strip, the limit
Sliding is provided with correcting rod parallel with main scale all the time on the bar of position.
By using above-mentioned technical proposal, when the first measuring claw is deep into hole, correcting rod is slid downwards, makes correction
Bar is bonded with the plane around hole, and correcting rod is parallel with main scale all the time, so that blade is vertical with the axis holding in hole, without more
Secondary regulation main scale position, simplifies measurement process, meanwhile, make measurement result more accurate.
Further, the first measuring claw lateral wall is provided perpendicular to positive stop strip for measuring the scale in aperture
Line.
By using above-mentioned technical proposal, the first measuring claw enters deeply into the pores, under the correcting of correcting rod, the first measurement
Pawl is deep into most deep position, and keeps vertical in hole, by observing the graduation mark on lateral wall, reads now correspondence position
Aperture, realize that a chi uses.
Further, the vernier lateral wall is provided with air level along main scale length direction.
By using above-mentioned technical proposal, in the centre-to-centre spacing of holes of the measurement on horizontal plane, by observing and adjusting
Section air level can make main scale horizontal, without correcting by correcting rod, be easy to measure.
In summary, the utility model has the advantages that：
1st, when need measure positioned at different height holes centre-to-centre spacing when, by the first measuring claw extend into relative position compared with
In low hole, then moving cursor, makes the second measuring claw be located in the higher hole of relative position, makes main scale and the axis in two holes
Keep vertical, then read reading, you can realize the measurement of the holes centre-to-centre spacing at different height；
2nd, it is generally aligned in the same plane but during the centre-to-centre spacing of the holes of diameter not etc. in measurement, can also passes through regulation first and survey
Stretch into amount of the measuring jaw in larger hole, makes main scale keep level, so as to realize the centre-to-centre spacing for measuring the holes that diameter does not wait；
3rd, by setting aperture graduation mark on the first measuring claw, hole can be measured after the first measuring claw is entered deeply into the pores simultaneously
Footpath, realize that a chi uses.
