Abstract
The present invention provides a kind of Novel leveling rod, including levelling rod blade, support bar and universal hinge, two pairs of both sides of levelling rod blade are provided with two support bars by the way that universal hinge is be hinged respectively, support bar is length adjustable structure, and the upper end of support bar is marked with graduation mark along its length with it by the universal side for being articulated with levelling rod blade, level ruler.It is poor to solve the precision of existing levelling rod measurement data and reliability, need to additionally take manpower during use, and light is weaker or night-environment under the problems such as can not measuring.The invention belongs to surveying and mapping tool field.
Description
Technical field
The present invention relates to a kind of levelling rod, belong to survey field.
Background technology
In Surveying and Mapping Industry, up to the present the utilization of levelling rod is all still quite varied, at present used levelling rod
Most of or straight-plate-type Double-face ruler（Red face and black flour）, it is known that in general levelling rod is required for people when in use
Helping can just be kept upright, and this uprightly because the reason for people influences, it be it is extremely unstable, it is necessary to workload compare
Greatly, main is the precision and reliability that can influence measurement data.It is current levelling rod in light that it, which also has a weak point,
Line is weaker or night-environment under can not measure, at work between it is tight, can not be required as early as possible in the case of being badly in need of data
Unit provides data.Therefore it is badly in need of the Novel leveling rod support that a kind of cost is low, stability is good and the level that can be measured at night
Chi.
The content of the invention
It is an object of the invention to：A kind of Novel leveling rod is provided, with solve the precision of existing levelling rod measurement data with
Reliability is poor, need to additionally take manpower during use, and light is weaker or night-environment under the problems such as can not measuring.
To solve the above problems, intend using such a Novel leveling rod, including levelling rod blade, support bar and universal
Hinge, two pairs of both sides of levelling rod blade are provided with two support bars by the way that universal hinge is be hinged respectively, and support bar is length adjustable
Structure, and the upper end of support bar is marked along its length with it by the universal side for being articulated with levelling rod blade, level ruler
It is carved with graduation mark.
In foregoing levelling rod, the support bar is expansion link, preferably electric expansion bar；
In foregoing levelling rod, the graduation mark is by long afterglow luminescent powder marking, or long afterglow is scribbled on graduation mark
Luminescent powder figure layer；
In foregoing levelling rod, strap is further fixedly arranged on the downside of levelling rod blade, for being incited somebody to action when transporting and shifting levelling rod
Support bar is fixed on blade volume both sides.
Compared with prior art, levelling rod provided by the invention, in two supports connected based on levelling rod blade both sides
Bar, each support bar with the side of blade two are connected by spherical universal joint, and two support bars can stretch.
During using the Novel leveling rod, the support bar of blade both sides is opened and stands on ground, to support levelling rod, by support bar
The regulation of support angle and length, make levelling rod state of being kept upright motionless；The Novel leveling rod is relative at present by artificial
For the levelling rod of holding, its stability is more preferable, and measurement accuracy is higher with reliability；And this levelling rod and center rest are one
Body, for other single support bars, lack the step of needing to connect manually between the two, saved time and manpower；
In addition, the Novel leveling rod adds long afterglow luminescent powder when delineating yardstick division line, the luminescent powder is in daylight or light
After irradiating lower extinction 5-20 minutes, effective continuous illumination can reach 8-10 hours, and reusable, and service life is up to 20
More than year, such surveyor can also measure work at night；Levelling rod bottom is designed with strap buckle, when no
Support bar and blade are fixed together by time, are convenient for carrying.The structure of the Novel leveling rod is simple, support is convenient, integral type branch
Support connected structure, convenient in carrying, the reliability height of measurement.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention；
Fig. 2 is Fig. 1 side view.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with accompanying drawing
The detailed description of step, it will be appreciated that specific embodiment described herein only to explain the present invention, is not used to limit this hair
It is bright.
Embodiment：
Referring to Figures 1 and 2, the present embodiment provides a kind of Novel leveling rod, including levelling rod blade 1, support bar 2 and universal hinge 3,
Two pairs of both sides of levelling rod blade 1 are provided with two support bars 2 by the way that universal hinge 3 is be hinged respectively, and support bar 2 is length adjustable
Expansion link, preferred electric expansion bar, hand-adjusting type support bar also can be selected, and the upper end of support bar 2 is articulated with by universal hinge 3
The side of levelling rod blade 1, universal cut with scissors can open up screwed hole on 3, lock-screw be installed with screwed hole, when the angle of support bar 2
After conciliation, support bar 2 can be held out against by screwing lock-screw, with locked support bar 2, avoid its rotation, on levelling rod blade 1
Graduation mark 4 is marked with along its length, and graduation mark 4 scribbles rare earth length by long afterglow luminescent powder marking, or on graduation mark 4
Twilight sunset luminescent powder figure layer, for the luminescent powder under daylight or light-illuminating after extinction 5-20 minutes, effective continuous illumination can reach 8-
10 hours, and it is reusable, and for service life up to more than 20 years, such surveyor can also measure work at night
Make, the downside of levelling rod blade 1 is further fixedly arranged on strap 5, without when support bar 2 and levelling rod blade 1 be fixed on
Together, it is convenient for carrying, integral type support connected structure, convenient in carrying, the reliability of measurement is high.
