Utility model content
The purpose of this utility model is that the adjustment that in raising prior art, laser curtain exists is loaded down with trivial details, the problem of inefficiency.
So a kind of laser light curtain laser instrument provided by the utility model, comprises housing, its special character is, is provided with laser module and is arranged on the right-hand member of housing and is placed in the conical surface mirror in the bright dipping light path of this laser module in described housing;
The right-hand member end of housing is connected with conical surface mirror holder by a junction, the axis of conical surface mirror moves towards described connecting portion one lateral deviation, and make distance between the axis of conical surface mirror and the axis of laser module between 0～4mm, the shoot laser of laser module gap between conical surface mirror holder and housing after this conical surface mirror reflection is penetrated; Connecting portion large or equal 90 ° along the angle between two ends of described housing, and little or equal 180 °.
Distance between the axis of the axis of above-mentioned conical surface mirror and laser module is between 0.3～0.7mm.
Distance between the axis of the axis of above-mentioned conical surface mirror and laser module is 0.4mm or 0.35mm or 0.5mm.
Above-mentioned laser module is coaxial with housing.
Above-mentioned conical surface mirror is arranged with a translucent cover outward.
Above-mentioned translucent cover is a hollow glass post, stretches out, and described conical surface mirror is overlapped therein in described housing.
Above-mentioned translucent cover is a ring glass circle, coordinate with described connecting portion by described conical surface mirror around.
The inner of above-mentioned hollow glass post is set in outside laser module front end.
The infrared laser that wavelength is 370～1064nm is installed in above-mentioned laser module.
The infrared laser that wavelength is 830nm is installed in above-mentioned laser module.
Feature of the present utility model is: by with the eccentric conical surface mirror of installing of laser module, project angle and be greater than the laser between 180 ° and 270 °, can realize and illuminate whole curtain at such laser instrument of the top of curtain installation, when use, only this laser instrument need be arranged on to the top of curtain, without repeatedly adjustment, and reduce the quantity of laser instrument, improve operating efficiency, reduced cost.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the laser light curtain laser instrument cutaway view that hollow glass post is installed.
Fig. 2 is the laser light curtain laser instrument cutaway view that annular glass collar is installed.
Description of reference numerals: 1, housing; 2, laser module; 3, conical surface mirror; 4, connecting portion; 5, conical surface mirror holder; 6, translucent cover; 7, infrared laser.
Detailed description of the invention
In order to overcome, the adjustment that in prior art, laser curtain exists is loaded down with trivial details, the problem of inefficiency, the present embodiment provides the laser instrument of the laser light curtain shown in a kind of Fig. 1, comprise housing 1, in housing 1, be provided with laser module 2 and be arranged on the right-hand member of housing 1 and be placed in the conical surface mirror 3 in the bright dipping light path of this laser module 2; The right-hand member end of housing 1 is connected with conical surface mirror holder 5 by a junction 4, the axis of conical surface mirror 3 moves towards described connecting portion 4 one lateral deviations, and make distance between the axis of conical surface mirror 3 and the axis of laser module 2 between 0～4mm, preferably between 0.3～0.7mm, the shoot laser of laser module 2 gap between conical surface mirror holder 5 and housing 1 after these conical surface mirror 3 reflections is penetrated, connecting portion 4 large or equal 90 ° along the angle between two ends of described housing 1, and little or equal 180 °.
Thus, the laser that laser module 2 projects is all incident upon on the face of axis one side (deviating from the face of connecting portion 4 one sides) of conical surface mirror 3, guarantee the light energy of the laser that conical surface mirror 3 launches, and large or equal 90 ° along the angle between two ends of described housing 1 due to connecting portion 4, and little or equal 180 °, make the angle in the gap between conical surface mirror holder 5 and housing 1 between 180 ° to 270 °, thereby guarantee to project the laser projection district of subtended angle between 180 ° to 270 °, the laser subtended angle that efficiently solves the general projection of existing laser is less than 180 °, cause and have to use two laser instruments to be used in conjunction with the problem that adjustment is loaded down with trivial details and cost increases.
The preferred 0.5mm of distance between the axis of light cone face mirror 3 and the axis of laser module 2, certainly, also can be according to actual design needs, making the distance between the two is 0.4mm or 0.35mm etc.
Generally, in the time manufacturing, laser module 2 and housing 1 coaxially can be arranged.
In order to prevent work influence or the corrosion to conical surface mirror 3 such as dust, steam, can be at the outer sheathed translucent cover 6 of conical surface mirror 3, as shown in Figure 1, this translucent cover 6 is hollow glass posts, in housing 1, stretch out, and will state conical surface mirror 3 and overlap therein, certainly, the inner of hollow glass post is set in outside laser module 2 front ends.
This translucent cover 6 can be also the ring glass circle shown in Fig. 2, this ring glass circle coordinate with connecting portion 4 by conical surface mirror 3 around, connecting portion 4 is blocked the breach of ring glass circle.
