In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1-5, the present invention discloses an adjustable lens fixing structure, which comprises a base 1 and an adjusting member; the base 1 is provided with an accommodating cavity 10 for accommodating the optical lens 4, two opposite side surfaces of the base 1 are respectively provided with a first adjusting groove 11 and a second adjusting groove 12, the first adjusting groove 11 and the second adjusting groove 12 are arranged oppositely at intervals and are not communicated, and the front end surface of the base 1 is respectively provided with a first screw hole 13 penetrating through the first adjusting groove 11 and a second screw hole 14 penetrating through the second adjusting groove 12; the adjusting piece comprises a first screw 21 screwed in the first screw hole 13 and a second screw 22 screwed in the second screw hole 14, so that the groove widths of the first adjusting groove 11 and the second adjusting groove 12 in the central axis direction of the accommodating cavity 10 are correspondingly adjusted by adjusting the screwing depths of the first screw 21 and the second screw 22 in the first screw hole 13 and the second screw hole 14 respectively.
When the base 1 is processed, on the basis of the existing base 1, the first adjusting groove 11 and the second adjusting groove 12 are respectively formed on the two opposite side surfaces of the base 1, so that the processing is simple, and the cost is reduced.
Particularly in conjunction with fig. 1 and 2. A first adjusting groove 11 is formed in a second outer side surface of the first outer side surface of the base 1 facing to the opposite side, the first adjusting groove 11 does not extend to the second outer side surface, and the base 1 is divided into a base rear side part 101 located at the rear side of the first adjusting groove 11 and a base main body located at the front side of the first adjusting groove 11 by the first adjusting groove 11; similarly, a second adjusting groove 12 is formed in the second outer side surface of the base 1 so as to be offset toward the first outer side surface, the second adjusting groove 12 does not extend to the first outer side surface, the base body is further divided into a base front side portion 102 located on the front side of the second adjusting groove 12 by the second adjusting groove 12, and an intermediate connecting portion 103 connected between the base rear side portion 101 and the base front side portion 102.
The first screw 21 is screwed with the base rear side portion 101 after passing through the first adjustment groove 11 from the base main body, and therefore, the groove width of the first adjustment groove 11 can be changed by adjusting the screwing depth of the tip of the first screw 21 and the base rear side portion 101. The second screw 22 is screwed with the intermediate connecting portion 103 after passing through the second adjustment groove 12 from the base front side portion 102, and therefore, the groove width of the second adjustment groove 12 can be changed by adjusting the screwing depth of the end of the second screw 22 and the intermediate connecting portion 103.
The accommodating cavity 10 is formed in the front end surface of the front side portion 102 of the base to facilitate the optical lens 4 to be placed and fixed in the accommodating cavity 10, and the optical lens 4 may be fixed in the accommodating cavity 10 by any one of the conventional methods (e.g., by means of glue, elastic members, or thread compression).
When the base rear side portion 101 is kept still or used as a reference, the position and the inclination angle of the accommodating chamber 10 with respect to the base rear side portion 101 can be changed by adjusting the groove widths of the first and second adjusting grooves 11 and 12. That is, when the laser performs optical path adjustment, the groove widths of the first and second adjustment grooves 11 and 12 are adjusted by the first and second screws 21 and 22, so that the position and the inclination angle of the optical lens 4 can be changed, the optical lens 4 can be adjusted to a proper position, the adjustment operation is simple, and the adjustment accuracy is high. Specifically, when the groove width adjustment amounts of the first adjustment groove 11 and the second adjustment groove 12 are identical, the position of the optical lens 4 can be changed without changing the inclination angle thereof; when the groove width adjustment amounts of the first adjustment groove 11 and the second adjustment groove 12 are not uniform, the inclination angle of the optical lens 4 can be changed.
The first adjustment groove 11 and the second adjustment groove 12 are both disposed across the accommodation chamber 10. That is, in the central axis direction of the accommodating chamber 10, the projections of the accommodating chamber 10 are overlapped on the projections of the first and second adjustment grooves 11, 12. This structure ensures that the groove widths of the first and second adjustment grooves 11, 12 can be adjusted according to the position and inclination angle of the base front side portion 101 with respect to the base rear side portion 101.
The base 1 is preferably made of an elastic material (for example, preferably hard elastic plastic, hard rubber). Therefore, the widths of the first adjusting groove 11 and the second adjusting groove 12 are easier to adjust, and the adjusting precision is more accurate, so that the best effect is achieved.
In the embodiment shown in fig. 3-5, the adjustable lens fixing structure further includes a mounting bracket 5, and the rear end surface of the base 1 is fixedly connected to the mounting bracket 5, that is, the base rear side 101 is fixedly connected to the mounting bracket 5. For example, the base 1 is positioned in the through-fitting hole 15, the fixing hole 51 is correspondingly provided in the mounting bracket 5, and the base 1 can be fixed to the mounting bracket 5 by inserting the fixing member 3 into the fixing hole 51 from the through-fitting hole 15.
The utility model discloses still disclose a laser instrument, including optical lens piece 4 and aforementioned adjustable lens fixed knot construct, wherein, optical lens piece 4 is fixed in holding chamber 10. In the embodiment shown in fig. 3-5, the base 1 is assembled and fixed on the housing of the laser through the mounting bracket 5, so that the assembly is simple and the universality is good.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
