Description
Technical field
The present invention relates to engineering survey product technical fields, are specifically that one kind is exempted to help levelling rod.
Background technology
In mapping operations, spirit level is one of indispensable instrument, it is used for elevation transference, so as to establish an association
The elevation system of tune；In building trade, from the levelling of the land of early stage, excavation of foundation pit, main body finally is built, until entire work
Journey terminates, and spirit level all plays an important role.Levelling rod is the instrument that ground point-to-point transmission difference in height is measured according to measurement of the level principle
Device.At present, most of levelling rod is mostly used made by timber, aluminium or fiberglass, and ruler length is mostly 3 meters, and two secondary for one, two-sided to make
With.
At present, the use of levelling rod is very universal during the measurement of the level, particularly when a wide range of measurement of the level is carried out
Need the station number set very more, and each station is required for reading forward sight and backsight reading twice, if routinely come, it is necessary to artificially help
The bottom centre of levelling rod is first placed in base leveling origin by ruler, and both hands, which buttress levelling rod, rocks it, due to due to levelling rod
Ruler body has certain altitude, and weight is larger, is rocked levelling rod is helped often to be present with, even if slight rocking also results in survey
There is deviation, accuracy in amount data.Although there is the levelling rod for exempting to help currently on the market, some base leveling origin positions are built
Vertical close wall side, causes such levelling rod that can not be placed into base leveling origin；Current levelling rod compares when adjusting vertical
Difficulty is transferred to accurately, can only carry out coarse adjustment by swinging levelling rod, cannot be completely accurate so as to position, and error can be step by step
Accumulation, finally reading probably transfinites when data are handled, once reading transfinites, must resurvey, if do not resurveyed
The quality of measurement can be influenced, and manpower and materials can be delayed by remeasuring.
The content of the invention
To solve the above-mentioned problems, the present invention provide one kind exempt to help levelling rod, can measurement when need not manually always
It helps, moreover it is possible to carry out fine adjustment, measurement data is accurate, and can measure the base leveling origin on wall side.
To achieve the above object, the technical solution adopted by the present invention is：
One kind is exempted to help levelling rod, and including levelling rod body, the levelling rod body one side is scale face, further includes fixation
Part, sliding part and regulating device, the fixing piece is cylinder and offers a rectangle bayonet, the rectangle bayonet and the water

One annular groove, described sliding part one end mutually agree with the annular groove and are slidably connected with the annular groove, the sliding part other end
With being pierced by the slip mouth and being fixedly connected with the regulating device, the regulating device is described to adjust dress at least provided with three
It puts including flexural pivot and supporting rod, the spherical shell of the flexural pivot is fixedly connected with the sliding part, the sphere of the flexural pivot and the branch
Strut is fixedly connected.
Further, a bottom surface of the fixing piece is equipped with fixing port, the fixing port and the annular groove mutual conduction, institute
It states one end that sliding part is connected with the annular groove and is equipped with an external thread rod, described external thread rod one end is fixed with the sliding part to be connected
It connects, the external thread rod other end is slidably connected through the fixing port and with the fixing port, and the threaded rod is equipped with a spiral shell
Mother, the nut slide for limiting the sliding part.
Further, further include locking device, the locking device includes internal thread bar and screw, the internal thread bar with
The screw thread connection, the spherical shell of the flexural pivot offer the mounting hole of a perforation, the mounting hole and the internal thread bar
It is fixedly connected.
Further, the screw thread bottom of the screw is equipped with skid-proof rubber.
Further, the supporting rod include adjusting rod, fixed link and regulating ring, described adjusting rod one end with it is described
The sphere of flexural pivot is fixedly connected, and the other end is intercalated in the fixed link, and described regulating ring one end connects with the adjusting rod screw thread
It connects, the other end is rotatablely connected with the fixed link.
Further, the one end of the fixed link away from the regulating ring is equipped with anti-skidding tip.
The invention has the advantages that fixing piece is fixedly connected with three faces of levelling rod, and levelling rod scale face will not
Fixture blocks, and the fixing piece during the measurement of the level is avoided to block levelling rod；What sliding part was slidably connected with fixing piece
Structure, even if base leveling origin in the place by wall, can also pass through the position of adjustment slide so that supporting rod can be to levelling rod
It is supported；Supporting rod is connected with flexural pivot so that supporting rod can adjust support angle, and what further increase was of the invention exempts to help water
Object staff is to the adaptability in measurement place；Regulating ring on supporting rod can adjust the verticality of levelling rod by a small margin, realize accurate
Measurement.

The side of fixing piece 2 is equipped with one and slides mouth 22, slides and an annular groove 23,3 one end of sliding part and annular groove are equipped in mouth 22
23 mutually agree with and are slidably connected with annular groove 23, and 3 other end of sliding part connects with being pierced by slide mouth 22 and fix with regulating device 4
It connects.Regulating device 4 can be slided on fixing piece 2, even if base leveling origin can also be adjusted close to the position of wall by adjusting
The support that levelling rod body 1 is realized in the position of device 4, avoids walls block regulating device 4, so as to levelling rod body 1 occur
Happening for base leveling origin can not be placed on.
One bottom surface of fixing piece 2 is equipped with fixing port 24, fixing port 24 and 23 mutual conduction of annular groove, sliding part 3 and annular groove 23
One end of connection is equipped with an external thread rod 31, and 31 one end of external thread rod is fixedly connected with sliding part 3, and 31 other end of external thread rod is worn
It crosses fixing port 23 and is slidably connected with fixing port 24, threaded rod 31 is equipped with a nut 32, and nut 32 is slided for limit slippage part 3
It is dynamic.Under the action of threaded rod 31 and nut 32, sliding part 3 can be fixed, so that regulating device 4 is fixed, avoid surveying
Due to the slip of sliding part 3 during amount, regulating device 4 is deviated, cause levelling rod body 1 vertical.
There are three regulating device 4 is set in the present embodiment, regulating device 4 includes flexural pivot 41 and supporting rod 42, flexural pivot 41
Spherical shell 411 is fixedly connected with sliding part 3, and the sphere 412 of flexural pivot 41 is fixedly connected with supporting rod 42.Supporting rod 42 is with flexural pivot 41
It is freely rotated, it, can be by adjusting the position of supporting rod 42 so that supporting rod 42 when base leveling origin is in the position of close wall
