Description
Technical field
The present invention relates to a kind of measurement is had with chi, more particularly to a kind of levelling staff of adjustable illuminating angle, belong to
Engineering measuring technology field.
Background technology
Level gauge is the instrument measuring the discrepancy in elevation between ground point according to measurement of the level principle, and levelling rod is that one kind is joined with level gauge
Close the scale carrying out the measurement of the level.Because the certainty of measurement of the measurement of the level is of a relatively high, and it is widely used in engineering survey, industry
The field such as measurement and geodesic survey.
At present, the level gauge of practical application can be divided into optical level and electronic level two class by its operation principle.?
In real work, big measurement work cannot will be carried out, such as under night-environment with avoiding: leveling observation, engineering night in tunnel
Between construct, and due to daytime vehicle produce vibration make certainty of measurement reduce and require vehicle at night rareness environment under carry out bridge
Beam dynamic and static load tests, settlement of highway observation etc..
However, because night illumination condition does not often reach intervisibility requirement, frequently with the photograph of lighting or pocket lamp
Bright mode assists and completes leveling observation, and this not only needs additionally to increase staffing, human cost increase, and brightness of illumination is not
Uniformly, lead to measurement effect not good.Particularly electronic level illuminance is required higher, illuminance is relatively low, light is uneven
On even or bar code ruler hypographous in the case of cannot reading.
In addition, in prior art Self-bringing lighting system levelling staff, lighting angle can not adjust, can not be according to measurement light
According to needing to be adjusted direction of illumination；And it is all exposed outside to draw graduated chi face in current levelling staff, is easily subject to
Mill causes to damage.
Content of the invention
Present invention is primarily targeted at, overcome deficiency of the prior art, provide a kind of one kind of new structure adjustable
The levelling staff of section light angle, is particularly well-suited to dark environment.
The technical problem to be solved be provide that structure is simple, make easily, cost relatively low, practical can
Adjust the levelling staff of light angle, not only overcome existing levelling staff to be difficult in night-environment smoothly be precisely accomplished measurement work
The shortcoming of industry, improves measurement efficiency, ensures certainty of measurement；And provide lighting angle adjustable, can be adjusted according to measurement requirement
Ensure after section that light is uniform and stable；Meanwhile, by draw graduated chi face give in a non-operative state to protect, abrasionproof and extend
Service life；Has the value in industry.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of levelling staff of adjustable illuminating angle, including the chi body with chi face, described chi face is along chi body axial length side

Two sides be connected to left cover and right cover plate with axial lengths such as chi bodies.
Wherein, described left cover is all buckled by the connector being connected with chi surface side side in a non-operative state with right cover plate
Be combined on chi face, in working order under can open around connector, described left cover and right cover plate are respectively provided with towards the plate face in chi face
There is the luminous source imposing illumination.
And, the radial direction one side of described chi body is provided with battery case and two-way switch, and described luminous source passes through two-way opened
Close and be arranged on accumulator in battery case and be connected and obtain power supply；The top of described chi body and/or bottom are provided with limited block, use
Carry out spacing when left cover and right cover plate are fastened on chi face.
The present invention is further arranged to: the radial dimension of described left cover and right cover plate is equal to the half of chi face diameter length.
The present invention is further arranged to: described groove is u-shaped.
The present invention is further arranged to: described limited block is distributed in the middle of the top of chi body and protrudes chi face place plane,
Including the fixed part being connected with chi body top and the spacing edge protruding chi face；Described left cover and right cover plate are contacted with spacing edge
Plate face be provided with the breach matching with spacing edge.
The present invention is further arranged to: the medial surface on described spacing edge is provided with the 3 row's illuminations imposing illumination towards scale
Lamp.
The present invention is further arranged to: described 3 row's illuminating lamps are the lamp body of 3 kinds of colors.
Compared with prior art, the invention has the advantages that:
By being provided with the left cover of luminous source and the setting of right cover plate and limited block, wherein left cover and right cover plate exists
All be fastened on chi face by the connector being connected with chi surface side side under off working state, in working order under can be around connector
Open, limited block is used for left cover and right cover plate and is fastened on carrying out spacing during chi face, and achievable lighting angle is adjustable, and according to survey
Amount provides uniform and stable light after requiring to be adjusted and accurately measures it is ensured that can be well in dark environment,
Save manpower expenditure, improve work efficiency；Give in a non-operative state to protect and have by drawing graduated chi face simultaneously
There is fastening limit function so that chi face is able to abrasionproof and increases the service life.
The above is only the general introduction of technical solution of the present invention, in order to be better understood upon the technological means of the present invention, under
Face combines accompanying drawing, and the invention will be further described.
