Abstract
The utility model discloses a kind of accurate survey tool of large scale caliber.The accurate survey tool of the large scale caliber can step up the size that pipeline calculates caliber by the measurement bar on total bar, spacing between on the inside of as two measurement bars, moving sliding sleeve is to being close to total bar, accurately calculated respectively with inside micrometer between two sliding sleeves and two measurement bars closest to distance between the tuning drive gear of sliding sleeve, so along with the distance between two measurement bars on total bar between uncalculated high range, large scale caliber can be accurately tested out, it is convenient and efficient, accurately.
Description
Technical field
It the utility model is related to a kind of survey tool, more particularly to a kind of accurate survey tool of large scale caliber.
Background technology
The accurate survey tool of existing caliber has inside micrometer, but inside micrometer can only accurately measure caliber very little
Pipeline, once exceed certain size, just can only be by the measurement diameter substantially of tape measure etc, therefore large-scale pipeline often ruler
There are larger error on very little.Therefore, how accurately to measure large scale caliber becomes the technical program technical problems to be solved.
Utility model content
In order to solve the above technical problems, the utility model devises a kind of accurate survey tool of large scale caliber.
The utility model adopts the following technical solution：
A kind of accurate survey tool of large scale caliber, including total bar, total bar inner hollow forms movable passageway, mobile logical
Both sides are respectively arranged with the movable block coordinated with movable passageway in road, and movable block is moved along movable passageway, passed through respectively on movable block
Wear and be threaded with screw, the two screw ends for being pierced by total bar both ends have been respectively fixedly connected with rotation of adjustment knob, total roofbolt face
Upper horizontal cross is provided with shifting chute, and shifting chute is connected with movable passageway, and measurement bar is fixedly connected with sliding block, and measurement bar is pierced by
Shifting chute, measurement bar is vertical with total bar, is provided with the scale strip parallel with shifting chute on total bar of shifting chute side, scale strip is every
Tuning drive gear is provided with a high range, tuning drive gear is parallel with measurement bar, is provided with slide in measurement bar, the company of slip on slide
Sliding sleeve is connected to, sliding sleeve is slided by slide along measurement bar.
Preferably, the sliding sleeve is U-shaped, on the outside of sliding sleeve both sides with measurement bar the right and left on the same line.
Preferably, the end of the rotation of adjustment knob is fixedly connected with motor.It can realize that rotation adjusts rotation by motor
The automation of button adjusting section.
Compared with prior art, the accurate survey tool of the large scale caliber can step up pipeline by the measurement bar on total bar
The size of caliber is calculated, is the spacing between two measurement bars inner side, moving sliding sleeve is to total bar is close to, respectively with internal diameter thousand
It is divided to ruler to accurately calculate between two sliding sleeves and two measurement bars closest to distance between the tuning drive gear of sliding sleeve, so adds two measurement bars
Between distance on total bar between uncalculated high range, you can accurately test out large scale caliber, it is convenient and efficient, accurately.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the utility model；
Fig. 2 is a kind of phantom of Fig. 1；
Fig. 3 is a kind of left view of Fig. 1；
In figure：1st, total bar, 2, rotation of adjustment knob, 3, measurement bar, 4, scale strip, 5, tuning drive gear, 6, slide, 7, sliding
Set, 8, movable block, 9, screw.
Embodiment
Below by specific embodiment, and with reference to attached drawing, the technical solution of the utility model is made further specifically to retouch
State：
Embodiment：Such as attached drawing 1, shown in attached drawing 2 and attached drawing 3, a kind of accurate survey tool of large scale caliber, including total bar
1, total bar inner hollow forms movable passageway, and both sides are respectively arranged with the movable block 8 coordinated with movable passageway in movable passageway, move
Motion block is moved along movable passageway, is extended through on movable block and is threaded with screw 9, and two are pierced by the screw end point at total bar both ends
Rotation of adjustment knob 2 is not fixedly connected with, and horizontal cross is provided with shifting chute on total roofbolt face, and shifting chute connects with movable passageway
It is logical, measurement bar 3 is fixedly connected with sliding block, measurement bar is pierced by shifting chute, and measurement bar is vertical with total bar, total bar of shifting chute side
On be provided with the scale strip 4 parallel with shifting chute, be provided with tuning drive gear 5 on each high range of scale strip, tuning drive gear is with surveying
Gauge rod is parallel, and slide 6 is provided with measurement bar, and sliding sleeve 7 is slidably connected on slide, and sliding sleeve is slided by slide along measurement bar,
Sliding sleeve is U-shaped, on the outside of sliding sleeve both sides with measurement bar the right and left on the same line, the end of rotation of adjustment knob is fixedly connected
Motor.The automation of rotation of adjustment knob adjusting can be realized by motor.
The accurate survey tool of the large scale caliber can step up the ruler that pipeline calculates caliber by the measurement bar on total bar
Very little size, is the spacing between two measurement bars inner side, and moving sliding sleeve is accurately calculated with inside micrometer respectively to total bar is close to
Closest to distance between the tuning drive gear of sliding sleeve between two sliding sleeves and two measurement bars, so add and do not calculated on total bar between two measurement bars
High range between distance, you can accurately test out large scale caliber, it is convenient and efficient, accurately.
Embodiment described above is a kind of preferable scheme of the utility model, not the utility model is made any
Formal limitation, also has other variations and remodeling on the premise of without departing from the technical solution described in claim.
