Description
Technical field
The utility model is related to engineering survey field, is related specifically to a kind of levelling rod with support.
Background technology
In engineering construction, engineer is frequently necessary to carry out every engineering survey to residing landform, and the measurement of the level is just
It is one of wherein important measure the item.But measurement must be carried out at the construction field (site), because field condition complexity is various, then add
Upper survey crew needs hand steered levelling rod, ensures that levelling rod is not rocked all around in measurement, to control the level on levelling rod
Bubble is placed in the middle, however, in measurement, the hand-held levelling rod of staff is hurried back and forth in each website, and labour intensity is big, and body quivers naturally
Tremble, also to control air level placed in the middle, not only increased the observation difficulty of observation person, extend time of measuring, and cause reading
It is inaccurate, add in same measurement point rotate blade again reading when, central point shifts, and causes reading more inaccurate, because
This, it is difficult to ensure that the accuracy of measurement.
The Chinese invention patent of patent publication No. CN102853818 is disclosed a kind of " portable level ruler support ".This hair
Bright patent is related to a kind of and accurate invar matching used portable rack of bar code levelling rod, and it is technically characterized in that：Including frame
The fixed mount of type structure and the telescope support being fixedly connected with the fixed mount, the fixed mount left and right sides are equipped with fastening dress
Put, levelling rod is arranged in the inside casing of the fixed mount by the fastener.
The Chinese invention patent of patent publication No. CN102661735 is disclosed a kind of " levelling rod founds foot pin ".It is of the invention special
Profit is related to carry a kind of vertical foot pin of high-precision levelling rod in survey engineering, and it is technically characterized in that：The vertical foot pin of the levelling rod is main
By cylindrical slide calliper rule groove, vertical foot pin pedestal, cuboid slide calliper rule groove, circular bubble and three shape size identical rack leg groups
Into.The invention effectively reduces the measurement error caused by the hand steered levelling rod of surveyor is rocked, and slow down surveyor steady
The fatigue that solid water object staff is produced.
In above-mentioned patent, after portable level ruler support fixes levelling rod, it is impossible to quick to rotate levelling rod to observe
Black, red face reading；The invention of the vertical foot pin of levelling rod, although levelling rod can be reduced and rock the error for causing, but wind-force is larger
When, rocking for levelling rod, and level shoe ground proximity can not be controlled against foot pin, it has not been convenient to surveyor's leveling.
The content of the invention
In order to overcome the shortcomings of above-mentioned levelling rod, the utility model provides a kind of levelling rod with support, the levelling rod
Not only in the case where effectively control levelling rod is rocked, the amount of labour of surveyor is reduced, and can conveniently rotate blade to observe
Black, red face reading, improves certainty of measurement.
It is as follows that the utility model solves the technical scheme that its technical problem used：
（1）A kind of levelling rod with support, by levelling rod plate, circular bubble, multi-directional ball node, expansion link, base, spiral
Structure, handle composition, it is characterized in that：The inward-facing hollow out 15mm ~ 20mm in levelling rod plate both sides, installs expansion link, levelling rod
Plate left surface installs circular bubble, and the levelling rod plate left and right sides is provided with handle, bottom mounting seat.
（2）The expansion link ground terminal is sharp cone distal, and the other end is connected by universal round node with levelling rod, and each stretches
There is a helical structure at bar middle part, and helical structure is turned clockwise, expansion link elongation, and helical structure rotate counterclockwise is stretched
Bar shortens.
（3）The base is made up of base plate, connecting pole and connector, and total height is 80mm, in addition, base plate is triangle steel
Plate, connecting pole uses multi-directional ball Node connectedness with base plate, and in the case of base plate can be made motionless, levelling rod plate turns along any direction
It is dynamic.
（4）Scale on levelling rod plate is marked since 80mm.
The beneficial effects of the utility model are：（1）The expansion link of the levelling rod with support can realize water with adjustment length
The balance of object staff, the stabilization of levelling rod can be kept in complex condition, reduce the amount of labour of surveyor, ensured the essence of measurement
Degree.（2）Levelling rod bottom with support is provided with base, and when the rotation in black, red face is needed, convenient operation saves the time.
（3）The levelling rod simple structure, cost is relatively low, it is easy to promote the use of.

Specific embodiment
Technical scheme is further described with instantiation below：
（1）A kind of levelling rod with support, by levelling rod plate 1, circular bubble 2, multi-directional ball node 3, expansion link 4, base
5th, helical structure 6, handle 7 are constituted, it is characterized in that：The inward-facing hollow out 15mm ~ 20mm in the both sides of levelling rod plate 1, installs flexible
Bar 4, the left surface of levelling rod plate 1 installs circular bubble 2, and the left and right sides of levelling rod plate 1 is provided with handle 7, bottom mounting seat 5.
（2）The ground terminal of the expansion link 4 is sharp cone distal, and the other end is connected by universal round node 3 with levelling rod plate 1, often
