Technical field
The utility model relates to a kind of level, especially relates to a kind of laser level, belongs to the instrument of surveying and mapping field.
Background technology
Level or title marker refer generally to send horizontal or vertical visible laser, are used at target face subscript water filling horizontal line or perpendicular line.Level is to utilize the reflection of light principle, and a branch of directional light is projected on the conical surface prism, and directional light can form the light of 360 degree through reflection in the space.360 degree light can be used for graticule in the instrument of surveying and mapping field.But the support problem of this conical surface mirror is not solved so far preferably.
The shortcoming of the supporting way of available technology adopting is always the light generation of conical surface prismatic reflection to be blocked, and the light that is used in measurement is discontinuous, and surveying work is brought inconvenience.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of level, can solve well the support problem of conical surface mirror.
To achieve these goals, the utility model adopts following technical scheme:
Level, comprise: conical surface prism and be used for the microscope base of fixed axoid prism, it is characterized in that, also comprise: be used for to conical surface prism throw light luminescence unit, be used for holding luminescence unit and make shell that its light can penetrate, be arranged on the printing opacity post that is used for connecting them between shell and the microscope base; Conical surface prism is fixedly connected with the shell formation by the printing opacity post with the side that is wholy set in shell that microscope base consists of.
Further, the printing opacity post consists of Central Symmetry with the center of conical surface prism.
Further, microscope base is right cylinder; Shell is the right cylinder concentric with microscope base.
In addition, with regard to the printing opacity post itself, the printing opacity post is made of optical glass; The printing opacity post is rectangular block.
Further, with regard to the particular location of printing opacity post, number, the plane parallel of the rectangular block area maximum of printing opacity post is in the central axis of conical surface prism.The printing opacity post is positioned at the edge of microscope base.The plane of the rectangular block area minimum of printing opacity post is perpendicular to the central axis of conical surface prism.The number of printing opacity post is 4.
Usefulness of the present utility model is: the utility model adopts the printing opacity post that conical surface mirror is supported, can effectively avoid the Problem of Shading of existing bracing or strutting arrangement, the printing opacity post processing that the utility model adopts is fairly simple, the depth of parallelism of printing opacity post is easy to be guaranteed, and also can effectively guarantee the precision of laser rays simultaneously.
Description of drawings
Fig. 1 is the cross-sectional view of level described in the utility model.
The implication of Reference numeral among the figure:
1, printing opacity post; 2, conical surface prism; 3, microscope base; 4, shell; The central axis of C, conical surface prism.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Fig. 1 is the cross-sectional view of level described in the utility model.
As shown in Figure 1, level of the present utility model comprises: luminescence unit (not shown), shell 4, microscope base 3, conical surface prism 2 and printing opacity post 1.
Wherein, luminescence unit is for generation of throwing the needed LASER Light Source of line; in order to protect luminescence unit; be provided with shell 4; luminescence unit is arranged on the inside of shell 4; need to prove; for the laser beam that luminescence unit is produced is applied; shell 4 inside are provided with corresponding optical system; and with regard to the structure of shell 4 itself, shell 4 should be able to make aurora light be penetrated to conical surface prism 2, and shell 4 can adopt uncovered or other the structure of an end; this is convenient to for general technician in this area is to realize, does not add at this and gives unnecessary details.
Side at the shoot laser light beam of shell 4 is provided with microscope base 3 and conical surface prism 2, conical surface prism 2 is catoptrons that one side has the cone minute surface, it can reflect beams of laser light, in use, through suitable adjustment, the laser beam that luminescence unit produces is incident upon and reflects the reflection ray that can form 360 degree full angles on the conical surface prism 2 again, can be used for throwing line and measure.
At this moment, optimal state is not have the object of any obstruction light between shell 4 and microscope base 3, but in order to make them consist of an integral body, still need they are linked together.
In the utility model, for realize firm connection simultaneously again the reduction of minimum degree the obstruction of light is provided with more than one printing opacity post 1 between microscope base 3 and shell 4; Because conical surface mirror and microscope base 3 itself have constant weight, and conical surface mirror also is the part of outbalance in the level, in order to guarantee structural strength, the number of printing opacity post 1 and the size of being connected or with can stablize connect and be supported for suitable, as preferably, the number of printing opacity post 1 can be selected even number, and adopt symmetrical mode to arrange, furthermore, as preferred version, printing opacity post 1 can consist of Central Symmetry with the center of conical surface prism 2, and the number of printing opacity post 1 is 4.
With regard to printing opacity post 1 itself, in order to realize blocking the light minimum level, printing opacity post 1 is made by optical glass, here the optical glass of indication is that the optical glass of narrow sense is colouless optical glass, we know that such optical glass has high radioparent characteristics, can make the maximum transmission of light.The characteristics such as particularly, the optical glass in the utility model preferably adopts the flint glass with high index of refraction and high dispersion, and such as K9, it is soft that it has matter, and density is large.
With reference to Fig. 1, as for the profile of printing opacity post 1, as preferred version, printing opacity post 1 is rectangular block, when printing opacity post 1 was rectangular block, the plane parallel of printing opacity post 1 area maximum was in the middle bobbin thread C of conical surface prism 2, and the plane of area minimum is perpendicular to the middle bobbin thread C of conical surface prism 2.In addition, impact minimizes on light in order to make printing opacity post 1, and we wish that printing opacity post 1 is more better away from conical surface prism 2, so as preferred version, printing opacity post 1 is positioned at the edge of microscope base 3.
And as preferred version, for the characteristics that adapt to 360 degree full angles projections and be convenient to arrange printing opacity post 1, microscope base 3 be right cylinder, and while shell 4 is the right cylinder concentric with microscope base 3.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
