Description
Technical field
The present invention relates to the field of leveling auxiliary device more particularly to a kind of leveling auxiliary devices based on bracket.
Background technique
Level is the instrument for establishing horizontal line of sight measurement ground point-to-point transmission height difference, and principle is to be surveyed according to measurement of the level principle
Height difference between amount ground point, main component has telescope, pipe spirit level (or compensator), vertical axis, pedestal, foot screw, by structure
It is divided into tilting level, automatic compensated level, laser level and digital level (also known as electronic level), by precision point
For precision level and ordinary level, essential important tool in level thing construction.
A-frame is a kind of for being supported to level, in order to which user preferably uses the auxiliary of level
Device, A-frame in the prior art include placement plate, and the bottom end circumference uniform distribution of placement plate is rotatably connected there are three casing,
And the lower inner part of each casing is slided and is provided with supporting leg, is provided between each casing and each supporting leg for locking each casing
With the locking bolt of the relative position of each supporting leg.A-frame in the prior art when in use, first by three supporting legs to put
Set and scatter centered on plate and support on the ground, then stretch out each supporting leg respectively with hand, adjustment placement plate to using height,
Then according to the flat conditions on ground, the extension elongation between each casing and each supporting leg is constantly regulate, and makes each casing and each
Relative position between leg is locked, to the preliminary Level tune of placement plate progress, the position for keeping placement plate region more horizontal,
Then level is mounted in placement plate, according to the micromatic setting on level, level is subjected to final accurate degree tune
Section, is then measured using level.
A-frame in the prior art needs people to bend over or squat down each self extending when carrying out preliminary Level tune
Each supporting leg is adjusted, and needs the horizontality according to placement plate, it is continuous to unclamp and lock locking bolt, to adjust each supporting leg
In the extension elongation of each inside pipe casing, operation is relatively complicated, causes workload to increase, working efficiency is low, and error is higher, and not
It is disconnected to bend over or squat up operation to be easy that people is made to generate dizziness, cause its use reliability lower.
Summary of the invention
Adjusting personnel are made not need frequently to bend over to adjust when levelness in order to adjust placement plate, for this purpose, the present invention provides
A kind of leveling auxiliary device based on bracket.
To achieve the above object, the invention adopts the following technical scheme:
