Description
Technical field
The utility model relates to elevation carrection fields, are a kind of laser automatic levels specifically.
Background technique
Level is a kind of optical survey instrument to be worked using horizontal line of sight.It is mainly used to measure each on ground
Height difference between point, is chiefly used in the national measurement of the level, railway construction, highway, airport, building engineering survey and large machines peace
Dress etc..It can satisfy various construction engineerings and measurement of the level requirement.In use, level is supported by tripod,
But existing three-legged support has the following problems: when (1) measuring outdoors, ground is usually uneven, after existing tripod support,
Its supporting surface is not usually horizontal plane, and level is placed on unhorizontal support planar survey, brings difficulty to measurement；(2) existing
Some tripods are usually that on a horizontal ground, can clearly read the height of tripod with graduated, but in injustice
Open air when, but can not directly read the height of tripod.
Utility model content
The utility model aim is intended to provide a kind of laser automatic level, no matter surveys on a horizontal ground
Amount, or measured on uneven ground, supporting surface can be relatively easy to adjust to level, reduce measurement difficulty.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of laser automatic level, including level ontology, the branch being detachably connected with the level ontology
Frame mechanism, the bracket institution include several telescopic rods and the hinged terminal pad of the telescopic rod top end, are uniformly arranged on institute
State several high fine-tuning structures in terminal pad, the fixed disk hinged with the top of high fine-tuning structure, the high fine-tuning
Structure includes support rod, screw rod, connecting rod, and the top of the support rod and the fixed disk are hinged, and the support rod is hollow
Structure, the top of the screw rod of the screw rod are plugged in inside the support rod, the bottom of the nut of the screw rod and the support rod
End is fixedly connected, and the bottom end of the screw rod of the screw rod is fixedly connected with the top of the connecting rod, is offered in the terminal pad
First through hole, the connecting rod passes through first through hole far from that one end of screw rod and extends to outside first through hole, and passes through bearing
It is rotatably connected with the terminal pad.
Utility model by adopting the above technical scheme carries out just step first with height of the telescopic rod to entire supporting structure
It is whole, after having adjusted, then fixed disk is adjusted to by level by high fine-tuning structure, then level ontology is fixed in fixed disk,
So that level ontology is placed in the horizontal plane, measurement difficulty is reduced.High fine-tuning structure passes through rotation connecting rod, connection
Bar drives screw rod rotation, so that support rod be driven to make the back and forth movement of vertical direction.By adjusting the height of each support rod, into
And fixed disk is on horizontal plane.
It further limits, is fixed with air-bubble level in the fixed disk.
When adjusting high fine-tuning structure, it can refer to air-bubble level, fixed disk can be made to be in horizontal plane as early as possible.
It further limits, tape measure is fixedly installed in the fixed disk bottom center, and the end of tape measure hangs with weight, the company
It connects and offers the second through-hole at disk center.
After fixed disk leveling, weight is hung over into tape measure end, tape measure by the effect of weight gravity, pass through the second through-hole to
Lower unwrapping wire, when weight touches ground, tape measure stops unwrapping wire, reads the length of tape measure, this length adds the thickness of fixed disk
The as height of level ontology from the ground.In measurement process, tape measure is driven by gravity completely, is completely in vertical plane, is surveyed
Height out is more accurate.
It further limits, the bottom end of the telescopic rod is hinged with sharp portion.
On the ground of out-of-flatness, sharp portion can be inserted into ground, to fixed tripod.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram that the utility model sharp portion is not inserted into ground；
Fig. 2 is inserted into behind ground structural schematic diagram when carrying out elevation carrection for sharp portion；
Main element symbol description is as follows:
Three telescopic rods 21, sharp portion 211, terminal pad 22, first through hole 221, the second through-hole 222, high fine-tuning structure
23, support rod 231, screw rod 232, nut 2321, connecting rod 233, fixed disk 24, air-bubble level 241, tape measure 242, weight
243, mounting hole 244.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
Technical solutions of the utility model further illustrate.
As shown in Figure 1, 2, a kind of laser automatic level, including level ontology and the level ontology can
The bracket institution of dismantling connection, the bracket institution include three telescopic rods 21 and the hinged terminal pad of the telescopic rod top end
If three high fine-tuning structures 23 22, being uniformly arranged in the terminal pad, with the top of high fine-tuning structure is hinged consolidates
Price fixing 24, the high fine-tuning structure include support rod 231, screw rod 232, connecting rod 233, the top of the support rod 231 with
The fixed disk 24 is hinged, and the support rod 231 is hollow structure, and the top of the screw rod of the screw rod 232 is plugged in the branch
Inside strut 231, the nut 2321 of the screw rod 232 is fixedly connected with the bottom end of the support rod 231, the screw rod 232
The bottom end of screw rod is fixedly connected with the top of the connecting rod 233, and first through hole 221 is offered in the terminal pad 22, described
Connecting rod 233 is passed through far from that one end of screw rod 232 and first through hole 221 and is extended to outside first through hole 221, and by bearing with
The terminal pad 22 is rotatably connected.
In preferred embodiment, air-bubble level 241 is fixed in the fixed disk 24.
In preferred embodiment, tape measure 242 is fixedly installed in 24 bottom center of fixed disk, and the end of tape measure 242 is hung
