Abstract
The utility model relates to a laser line-projection device which simultaneously has point and line projections, which comprises a casing and a hanging system, wherein the hanging system is provided with a first laser and a first light splitting element which can emit linear laser beams, and is further provided with a second laser and a second light splitting element which can emit a plurality of laser points. As the device simultaneously has the point and line projections, and users can obtain the horizontal or vertical laser lines through using the linear laser beam, and can obtain the farther projection distance through using the projection of the laser points, and the energy consumption of point projections is lower, and the energy resource can be saved.
Description
Technical field
The relevant a kind of laser level of the utility model particularly possesses the laser level of dotted line projection the time far away, low in energy consumption relevant for a kind of operating distance.
Background technology
Laser level is as a kind of engineering instrument, and the occasion of its use is more and more.Existing laser level generally comprises housing, laser instrument and beam splitter.Laser instrument and beam splitter were incorporated in the body, and the laser instrument in housing sends single laser wire harness, through the branch light action of beam splitter, and meeting formation level or vertical light on object.Like this, trying to achieve the occasion of level or vertical curve at needs, can be that benchmark carries out operation with above-mentioned light.The laser stronger owing to output power can damage retina after mistake is injected human eye, therefore at civil area the output power of laser tool is had the restriction of strictness.It is the laser instrument of CLASS II that present laser level generally all adopts grade, and its laser output power is not more than 1Mw.But such laser rays can consume more energy when propagating in air, therefore, can not reach operating distance far away.In case distance is far away, then the laser rays on object is dark excessively, and effectively identification is not suitable for throwing on a large scale the line operation.In order to address the above problem, in some special occasions, can get some laser spots, because the concentration of energy of luminous point, it can carry out longer-distance operation.Therefore the laser level of luminous point has appearred penetrating.
Yet, only there are some luminous points sometimes can't carry out work, also need to assist by some light simultaneously, whether be fit to effect with the luminous point of determining to be got, and luminous point also can carry out preliminary location, make the operator seek the position of some distant light according to the position of luminous point, after the laser spots of determining is in correct position, can close laser rays, only rely on laser spots to carry out operation, so also can reduce the consumption of energy.At this moment need to have simultaneously the operation of luminous point and light, and save energy consumption in operating process, traditional like this laser level is no longer suitable.
Therefore, how to solve the problem that same laser level get laser rays and laser spots simultaneously and seem very important.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the laser level of dotted line projection is provided when providing a kind of operating distance far away, low in energy consumption.
In order to solve technical matters of the present utility model, the utility model provides a kind of laser level that possesses the dotted line projection simultaneously, have housing and hanging system, the hanging system is provided with first laser instrument and first beam splitter, can emitting linear shape laser beam, also have second laser instrument and second beam splitter, can launch a plurality of laser spots.
The utility model also has following feature, the linear laser Shu Kewei horizontal line that described first beam splitter sends, also can be vertical curve, and the 3rd laser instrument and the 3rd beam splitter, it sends and the perpendicular laser beam of the formed laser beam of first beam splitter, and a plurality of laser spots that described second beam splitter sends are five, comprise an opposite behind reference point of linear laser Shu Fangxiang of launching with first beam splitter in the above-mentioned laser spots.
By said structure, the laser level that possesses the dotted line projection simultaneously of the present utility model is because have light and luminous point, so operating distance is far away, and the energy consumption of luminous point is lower, can save the energy.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 possesses the three-dimensional exploded view of the laser level of dotted line projection simultaneously for the utility model is a kind of.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
See also Figure 1 and Figure 2, a kind of laser level that possesses the dotted line projection simultaneously of the utility model comprises housing (figure does not show), one is positioned the hanging system 1 in the above-mentioned housing, this hanging system 1 comprises first joint face 11, second joint face 12 and the 3rd joint face 13, wherein form first connecting hole 111 on first joint face 11, form second connecting hole 121 (figure does not show) on second joint face 12, and formation the 3rd connecting hole 131 on the 3rd joint face 13, second joint face 12 and the 3rd joint face 13 are oppositely arranged, thereby second connecting hole 121 and the 3rd connecting hole 131 are on the same straight line.First joint face 11 of hanging system 1 is provided with first light laser 21 and first beam splitter 22, and it is contained in first connecting hole 111 after installing, and first laser instrument, 21 emitted laser form vertical laser wire harness behind first beam splitter 22.Second joint face 12 of hanging system 1 is provided with second light laser 23 and second beam splitter 24, it is contained in second connecting hole 121 after installing, second laser instrument, 23 emitted laser, five laser spots behind second beam splitter 24, and above-mentioned laser spots comprises a reference point behind.The 3rd joint face 13 of hanging system 1 is provided with the 3rd light laser 25 and the 3rd beam splitter 26, and it is contained in the 3rd connecting hole 131 the laser wire harness of the 3rd laser instrument 25 emitted laser formation level behind the 3rd beam splitter 26 after installing.Aforesaid behind reference point is opposite with the vertical laser wire harness direction that the 3rd laser instrument 25 sends, on the projection object behind.
In the utility model, the formed laser spots of second laser instrument can be formed on first laser instrument and the formed laser rays of the 3rd laser instrument, also can be provided with separately, and the behind reference point, also can be in order to adjust the accuracy of projection.
The utility model has been finished designer's purpose of design, can form the laser line beam simultaneously, also can form the laser rectilinear point, and behind the position of determining laser spots, can close the laser line beam, to cut down the consumption of energy.
