The exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, however, the present invention may be embodied in many different forms and is not limited to the embodiments described herein, which are provided for complete and complete disclosure of the present invention and to fully convey the scope of the present invention to those skilled in the art. The terminology used in the exemplary embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, the same units/elements are denoted by the same reference numerals.
Unless otherwise defined, terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Further, it will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense.
It should be noted that the angle adjusting mechanism of the optical instrument provided by the present invention is applicable to all optical instruments that need to adjust the direction of the optical axis, such as an optical sighting telescope, an internal red pointing telescope, a laser pointer, and a structure that needs a mechanical axis coaxial with the optical axis.
The present embodiment provides a small laser as shown in fig. 3, 4 and 5, which comprises a housing 1 as shown in fig. 1 and 2, a horizontal adjusting screw 4 and a vertical adjusting screw 11 vertically disposed on the adjacent side of the front end of the housing 1, and a protective glass 3 disposed at the light exit hole of the front end of the housing 1, and is different from that shown in fig. 1 or 2 in that, in order to ensure the stability of the horizontal adjusting screw 4 and the vertical adjusting screw 11 during use, a first inclined damping hole 14 obliquely intersecting with one side of the horizontal adjusting screw 4 is formed on the rear side of the front end of the housing 1 as shown in fig. 5, a horizontal damping limiting column 13 is fixed in the first inclined damping hole 14 and then abuts against one side of the horizontal adjusting screw 4, thereby laterally pressing and limiting the horizontal adjusting screw 4, preventing the horizontal adjusting screw 4 from loosening caused by rotation due to external force vibration, thereby the stability of the left and right angles of the laser module 2 is ensured, and the guarantee of the use precision and the reliability is facilitated.
In order to ensure the stability of the vertical adjusting screw 11 during the use process, a second inclined damping hole 15 obliquely intersecting with one side of the vertical adjusting screw 11 is formed at the rear side of the front end part of the shell 1 shown in fig. 5, a vertical damping limiting column 12 is arranged in the second inclined damping hole 15, and the vertical damping limiting column 12 is fixed in the second inclined damping hole 15 and then abuts against one side of the vertical adjusting screw 11, so that the lateral extrusion limiting of the vertical adjusting screw 11 is realized, the vertical adjusting screw 11 is prevented from rotating due to external force vibration, the vertical adjusting screw 11 is prevented from loosening due to rotation of the vertical adjusting screw 11 due to external force vibration, the stability of the pitch angle of the laser module 2 is ensured, and the use precision and the reliability of the laser module are ensured.
This embodiment is through setting up horizontal damping spacing post 13 and the spacing post 12 of perpendicular damping from the slope side to contradict horizontal adjustment screw 4 and the vertical adjustment screw 11 after the stability, has effectively prevented horizontal adjustment screw 4 and vertical adjustment screw 11 not hard up because of external vibration, does benefit to and ensures the stability and the precision of this little laser instrument.
The horizontal damping limiting column 13 and the vertical damping limiting column 12 are made of nylon materials and have good elastic deformation, and the horizontal damping limiting column 13 and the vertical damping limiting column 12 can be pressed on the horizontal adjusting screw 4 and the vertical adjusting screw 11 by means of elasticity of the horizontal damping limiting column 13 and the vertical damping limiting column 12, so that positioning is achieved.
In view of the fact that most of the protective glass in the existing laser is arranged perpendicular to the axis of the housing or the optical axis of the emergent light, which causes the power attenuation of the emergent light due to the reflected light returned from the original path, the embodiment sets the protective glass 3 obliquely (see fig. 6) to ensure that the included angle between the reflected light path and the incident light path is greater than zero, thereby effectively avoiding the defect that the actually emergent light power is reduced due to the fact that the reflected light is overlapped with the incident light path incident on the protective glass and the direction is opposite, ensuring that the reflected light spot is not reflected to the photoelectric sensor in the laser tube, and causing the problem of poor output power stability, so as to ensure the power stability of the laser output, and meanwhile, the protective glass is added, ensuring the sealing performance of the laser, and prolonging the service life of the product.
In conclusion, it is easy to see that by additionally arranging a horizontal damping limiting column or a vertical damping limiting column which can generate cross interference with a horizontal adjusting screw or a vertical adjusting screw, the interference on the horizontal adjusting screw or the vertical adjusting screw is realized by the elastic deformation of the horizontal damping limiting column and the vertical damping limiting column, so that the contact force or the fixing stability between the horizontal adjusting screw or the vertical adjusting screw and the screw hole is fastened, the anti-seismic performance is improved, and the use stability of the horizontal adjusting screw or the vertical adjusting screw is ensured; meanwhile, the protective glass is obliquely arranged, so that the phenomenon that the power of emergent light of the sighting device is reduced due to the fact that reflected light returns along the light path of incident light (the light incident on the protective glass is emergent light of the sighting device) is avoided.
