Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of levelling rod provided by the utility model；
Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1.
Specific embodiment
The utility model discloses a kind of levelling rods, improve the measurement accuracy of leveling work.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, Fig. 1 is the structural schematic diagram of levelling rod provided by the utility model；Fig. 2 is the transversal of Fig. 1
Face structural schematic diagram.
This case provides a kind of levelling rod, including ruler body 1, and ruler body 1 includes the first bar code water arranged along its length
Quasi- face 11 and the second bar code level surface 12, the first bar code level surface 11 and the second bar code level surface 12 are located at ruler body width side
To two sides.Ruler body 1 can be respectively by arranging the first bar code level surface 11 and the second bar code level surface 12, together along its length
Shi Jinhang elevation carrection twice, the first bar code level surface 11 and the second bar code level surface 12 are located at the two sides of ruler body width direction,
Two groups of measurement data can be obtained simultaneously, increase observation frequency, by the processing to two groups of height measurement results, improve observation essence
Degree avoids the accumulation of error, improves measurement accuracy.
In one specific embodiment of this case, ruler body 1 is the ruler body of triangular prism structure, the first bar code level surface 11 and Article 2
Code level surface 12 is located on the faceted pebble of triangular prism structure ruler body.Ruler body 1 is set as triangular prism structure, in measurement process, leads to
It crosses and original place rotation is carried out to the ruler body of triangular prism structure, rotation amplitude is small, elevation carrection face can be carried out the first bar code level
The switching in face 11 and the second bar code level surface 12, the first bar code level surface 11 is identical with the structure of the second bar code level surface 12, protects
Two bar code level surface measurement data identity are demonstrate,proved, triangular prism structure is not implemented only in equipment difference measurement level surface on ruler body
It is required that and structure it is simple, it is easily operated, avoid the switching of measuring surface that measurement error is caused to increase.
In one specific embodiment of this case, the back side of triangular prism structure ruler body, which is provided with, is adjusted the vertical degree of ruler body
Air-bubble leveling ruler 3.When levelling rod measures, need to guarantee the vertical of the first measurement of the level face 11 and the second level measuring surface 12
It spends, guarantees to obtain accurate altitude information in height measurement process, triangular prism structure ruler body utilizes two faceted pebble in-process measurement water
Air-bubble leveling ruler 3, operator behaviour is arranged at the back side of ruler body using not used third faceted pebble as the back side of ruler body in quasi- face
When making levelling rod, positioned at the back side of levelling rod, levelling rod can be corrected by the position of bubble in observation air-bubble leveling ruler,
Guarantee its vertical degree, is further ensured that the accuracy of measurement result.
It in one specific embodiment of this case, is additionally provided on ruler body 1 and stretches out along its length, its measurement direction is carried out
Rotate the rotary shaft 2 of adjustment.When carrying out elevation carrection using levelling rod, needs to rotate and realize the first bar code level surface 11 and second
The switching of bar code level surface 12 be easy to cause the displacement of rotation process levelling rod to cause measurement result twice due to manual operation
Difference is larger.Rotary shaft 2 is set in ruler body, and rotary shaft 2 is stretched out along the length direction of levelling rod, in rotation, by rotary shaft 2
It is supported with monitoring point, ensure that and measure twice, levelling rod is measured as the altitude information of same position.
Specifically, the bottom of ruler body 1 is provided with the rotating stand of frame support rotary shaft.In the setting support rotation of the bottom of levelling rod
The rotating stand of shaft, rotating stand can be played to support levelling rod simultaneously and be positioned, and to the function that ruler body is protected.
In one specific embodiment of this case, offered in the middle part of the ruler body of triangular prism structure arrange along its length it is logical
Hole, rotary shaft are rack-mounted in through-hole.Rotary shaft is set to the middle part of level ruler body, it, will for the ruler body of triangular prism structure
The through-hole of installation rotary shaft is opened in the center of ruler body, when operating levelling rod, by the support of rotary shaft bottom and monitoring point, with
And rotary shaft is to the rotational positioning of levelling rod, so that the error of position and measurement initial position after levelling rod rotation is as far as possible
It is small, further increase measurement accuracy.
Since levelling rod is in measurement process, the position by artificially observing air-bubble object staff positions the vertical of levelling rod
Degree.By the way that the first bar code level surface 11 and the second bar code level surface 12 are arranged on levelling rod, using rotary shaft 2 to levelling rod
Rotational positioning obtains the first observation A by the first bar code level surface 11, is obtained by the second bar code level surface 12 in measurement
Obtain the second observation B.
For the requirement of second-order levelling, the reading twice that the first observation A and the second observation B is arranged allows most
Large deviation value passes through according to measured result if the difference of the first observation A and the second observation B are located in maximum deflection difference value
The two average value is taken to obtain final measurement；Otherwise, then explanation there may be observation when levelling rod do not keep it is vertical or
The problems such as level does not flatten, it is therefore desirable to exclude problem above immediately, observe again, until make twice difference of reading it is maximum partially
In difference range, while seeking observation of the average value read twice as this time.
The levelling rod that this case provides by the way that multiple bar code level surfaces are arranged, and switches difference in the way of rotary ruler body
Bar code level surface, it is larger to reduce the measurement data deviation due to caused by manual operation error or equipment error to the greatest extent,
The accuracy for improving elevation carrection reading reduces the accumulation of error, improves measurement accuracy.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
