The specific embodiment
Embodiment one
The optical principle of present embodiment is settled whole prism 1-5 as shown in Figure 1 on the light path of laser generator 1-6 transmitting terminal, this prism has the reflective surface A as the beam split reflective surface B of previous stage and conduct back one-level.Beam split reflective surface B and reflective surface A are parallel to each other, and all with the optical axis of laser generator angle at 45, reflective surface A is positioned on the reflected light path of beam split reflective surface B.Reflecting when passing the B face for fear of transmitted ray, fits in the inclined-plane of beam split reflective surface B and right angle prism 1-8.In this embodiment, the reflective ratio of the beam split of beam split reflective surface B is 1: 1, when therefore working, be derived from laser generator 1-6 laser R0 half pass beam split reflective surface B and prism 1-8, form transmitted light R1, second half reflexes to reflective surface A through beam split reflective surface B simultaneously, again by this face reflection, form the reflection R2 parallel, thereby will be separated into two-way with source laser R0 with transmitted light.
Fig. 2 and Fig. 3 are the concrete structure signal of present embodiment homologous light separation marking device, and columniform laser generator 1-6 plug-in mounting is fixed in the perforation of rectangular box shape housing 1-2 rear end.The through hole of prism bracket 1-7 rear end is sleeved on the front end (transmitting terminal) of laser generator 1-6, forms hinges each other.Whole prism 1-5 with parallel beam split reflective surface B and reflective surface A is fixed among the prism bracket 1-7, and the beam split reflective surface of whole prism 1-5 is positioned on the light path of laser generator 1-6, and reflective surface A is positioned on the reflected light path of beam split reflective surface B.Fitting in the front end of whole prism 1-5 beam split reflective surface B and the inclined-plane of right angle prism 1-8, constitutes the prism group, thereby can avoid transmitted ray to reflect when passing the B face.The transmitted light path of prism group and reflected light path front end are respectively equipped with corrugated mirror 1-1, and two corrugated mirrors are fixed in the fenestra at cover plate 1-9 middle part, and cover plate 1-9 is fastened on the front end of housing 1-2, and therefore the laser beam that laser generator is sent becomes covering of the fan light.When the ripple direction of two corrugated mirrors was parallel to each other, homology was separated the laser covering of the fan and is parallel to each other, and can form the parallel laser graticule on shone thing; When the ripple direction of two corrugated mirrors was vertical mutually, it is vertical mutually that homology is separated the laser covering of the fan, can form the intersection straight line laser on shone thing.
In order to regulate the spacing of the parallel separation straight line laser of two homologies as required, the both sides of housing 1-2 are equipped with fastening nail 1-4 and 1-3 respectively, and the termination of two fastening nails can hold the both sides at prism bracket 1-7 respectively.By regulating two fastening nails, can change the setting angle of prism bracket 1-7 in housing 1-2, separate the spacing L of two-way laser thereby change homology in the horizontal plane projection.The regulative mode of straight line laser spacing is not limited to the foregoing description.One of them fastening nail among Fig. 2 can be replaced by a spring; In addition, can also change the angle of prism bracket with other many feasible patterns, thereby finally change the spacing of straight line laser.
