Description
Technical field
This utility model belongs to projective iteration instrument field, particularly relates to a kind of portable axis positioning projection instrument, and it is main
If downward for axis projective iteration is used by construction.
Background technology
In production practices, axis is projected downwards by many employing weight lines, during weight line projection, due to by artificial and outer
The impact of boundary's environment (such as wind), weight is easily generated random rocking, and location and positioning precision are produced large effect, precision
The highest, inefficiency.In order to overcome this problem, the most conventional way is to use theodolite to carry out axis projections location, but
This kind of method operation complexity, needs professional to operate, relatively costly, inefficiency, and is limited by site condition, Ke Nengwu
Method disposes instrument, it is impossible to effectively meet the needs used.
Projection accuracy, lower cost the most how are effectively ensured, and improving efficiency is a problem required study.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of portable shaft line projection position finder, it is intended to solve
The deficiency of Current projection positioner, and can effectively simply observe the vertical guide of axis and its picture composition, thus effectively
Ground orientation axis projection on matrix face.
This utility model is achieved in that a kind of portable shaft line projection position finder, including containing oil (liquid) body
Body and mobile device, described mobile device is arranged on the bottom of body, body can be made to move freely on matrix to be projected, institute
Stating body is opaque box body, and its top is provided with transparent box cover, and described transparent box cover is provided with and overlaps with transparent box cover major axis
Longitudinal projection's silk thread and be symmetrically distributed in the graduation mark of longitudinal projection's silk thread both sides, the long end in bottom two of described opaque box body
Side is respectively equipped with reference mark line.
Further, containing liquid or oil body in described opaque box body, the height of oil (liquid) body occupies opaque box body
2nd/to three/3rds of height so that it is be easy to the horizontal minute surface of formation, oil (liquid) body has preferable viscosity (anti-liquid level
Rock) and good mirror effect.
Further, described graduation mark is symmetrically distributed in longitudinal projection's silk thread both sides, and scale is degree, minute, second, and precision is
Second, tolerance angle is the complementary angle at the inclination angle of the plane that longitudinal projection's silk thread is formed at projection and the graduation mark of cassette bottom.
Further, described reference mark line is positioned at cassette bottom long end both sides, and scale is centimetre, millimeter, and precision is millimeter.
This utility model makes full use of the projection of mirror imaging principle orientation axis, and it is according to mirror imaging principle, as
Vertical with plane mirror with the line of object, therefore linear object in horizontal minute surface as the plane that forms with this object and level
Minute surface is vertical, and i.e. object is with as composition vertical guide, and this vertical guide is object in matrix face with the intersection in matrix face to be projected
On projection.
This utility model compared with prior art, has the beneficial effects that: this utility model can effectively simply observe
The vertical guide that axis forms with its picture, thus efficiently locate axis projection on matrix face；This utility model simple in construction
Rationally, can effectively ensure that projection accuracy, reduce cost, improve efficiency, be convenient for carrying, bring the most just to construction personnel
Prompt.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Embodiment
As Figure 1-3, a kind of portable shaft line projection position finder is present embodiments provided, including containing oil (liquid) body
Body and mobile device 7, described mobile device 7 is arranged on the bottom of body, and described body is opaque box body 1, its top
Being provided with transparent box cover 3, contain liquid or oil body in described opaque box body 1, oil (liquid) body has good mirror effect, and
The height of oil (liquid) body occupies 2nd/to three/3rds of opaque box body 1 height, in order to form horizontal minute surface, described
Transparent box cover 3 is provided with the longitudinal projection's silk thread 4 overlapped with transparent box cover 3 major axis and is symmetrically distributed in 4 liang of longitudinal projection's silk thread
The graduation mark 5 of side, the long end in bottom of described opaque box body 1 is respectively provided on two sides with reference mark line 6, described mobile device 7 energy
Opaque box body 1 is made to move freely on matrix to be projected.
Wherein, described graduation mark 5 is symmetrically distributed in longitudinal projection's silk thread 4 both sides, and scale is degree, minute, second, and precision is the second,
Tolerance angle is the complementary angle at the inclination angle of the plane that longitudinal projection's silk thread 4 is formed at projection and the graduation mark 5 of cassette bottom；Described mark
Note graduation mark 6 is positioned at cassette bottom long end both sides, and scale is centimetre, millimeter, and precision is millimeter.
This utility model utilizes oil (liquid) body 2 to form horizontal minute surface, on the one hand longitudinal projection's silk thread 4 and in oil (liquid) face
On as forming vertical guide I, on the other hand treat the axis projected downwards and on oil (liquid) face as forming vertical guide II, make
Used time, user Mobile portable formula axis projections position finder, when observing longitudinal projection's silk thread, the picture of longitudinal projection's silk thread and treating
The axis of projection as three overlap time, vertical guide I and vertical guide II overlap, longitudinal projection's silk thread as being axle to be projected
Line projection on matrix, can be marked on projection matrix by reference mark line, be completed location.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
