Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Based on this, as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides an optical lens 4 holder, an optical device and a laser system, wherein the optical lens 4 holder includes an adjusting base 2, a mounting base 1 and a fixing structure. The adjustment seat 2 has a first spherical surface 2a and a first optical hole. The mount 1 has a second spherical surface 1b and a second optical hole 1 a. The first spherical surface 2a and the second spherical surface 1b are matched, so that the adjusting seat 2 can rotate relative to the mounting seat 1, and the included angle between the center line of the first optical hole and the center line of the second optical hole 1a is adjusted. The first optical aperture and the second optical aperture 1a are opposed so that light passing through the first optical aperture enters the second optical cavity. The fixing structure is used for fixing the adjusting seat 2 on the mounting seat 1.
In this embodiment, since the adjusting seat 2 and the mounting seat 1 are adapted to each other by a spherical surface, the adjusting seat 2 can swing in different directions, thereby solving the technical problem of monotonous adjusting direction of the adjusting seat 2 in the prior art. The adjusting seat 2 can swing to different directions so that the adjusting angle of the adjusting seat 2 is more accurate. Because the adjusting seat 2 and the mounting seat 1 adjust the included angle between the center line of the first optical hole and the center line of the second optical hole 1a through the first spherical surface 2a and the second spherical surface 1b in a matching way, the included angle is hard contact, and elastic fatigue does not exist. Therefore, the adjustment base 2 and the optical lens 4 are relatively stable.
In some embodiments, as shown in fig. 1, 2, 3 and 4, the first optical aperture extends through the first spherical surface 2a and the second optical aperture 1a extends through the second spherical surface 1 b.
The first spherical surface 2a and the second spherical surface 1b are adapted to adjust the angle between the center line of the first optical hole and the center line of the second optical hole 1 a. Therefore, the first optical hole penetrates the first spherical surface 2a, and the second optical hole 1a penetrates the second spherical surface 1b, thereby improving the adjustment accuracy.
In some embodiments, as shown in fig. 1, 3 and 4, the adjustment seat 2 is outwardly convex to form a first spherical surface 2a, and the mounting seat 1 is inwardly concave to form a second spherical surface 1 b.
Based on the above embodiments, in some embodiments, since the first optical hole penetrates through the first spherical surface 2a, if the first spherical surface 2a is formed by the adjusting seat 2 being recessed inwards, the first spherical surface 2a occupies the installation space of the optical lens 4. That is, the adjustment seat 2 has to be made wider to reserve a space for mounting the optical lens 4 and a space for the first spherical surface 2 a. This results in a bulky and non-compact structure of the holder for the optical lens 4.
In some embodiments, as shown in fig. 1, 3 and 4, the centre line of the first optical aperture coincides with the radius of the first spherical surface 2 a; the center line of the second optical aperture 1a coincides with the radius of the second spherical surface 1 b.
This embodiment can avoid the light beam passing through the first and second optical holes 1a from being blocked during the rotation of the adjustment seat 2, so that the light is lost.
In some embodiments, as shown in fig. 1 and 4, the first optical aperture comprises: a first aperture section 2b and a second aperture section 2c, the aperture of the first aperture section 2b being larger than the aperture of the second aperture section 2c, the first aperture section 2b forming a step 2d where it meets the second aperture section 2c for fitting the optic 4.
In the present embodiment, the step 2d for assembling the optical lens 4 is formed at the joint of the first aperture section 2b and the second aperture section 2c, and the optical lens 4 is placed in the first aperture, which helps to protect the optical lens 4 and prevent the optical lens 4 from being damaged by external force.
In some embodiments, as shown in fig. 1 and 5, the optics frame 4 further comprises: a retainer ring 3; the retainer ring 3 is used for fixing the optical lens 4 on the step 2d, and the retainer ring 3 is in threaded connection with the first aperture section 2 b. In some embodiments, the retainer ring 3 is provided with an elastic opening 3a, and when the retainer ring 3 is rotated to install the retainer ring 3 into the first bore section 2b and move out of the first bore section 2b, a screwdriver is clamped into the elastic opening to apply external force to the retainer ring 3 to rotate the retainer ring 3.
The optical lens 4 is fixed on the step 2d by the retainer ring 3, and the optical lens 4 is fixed in a manner that the optical lens 4 and the optical lens 4 holder are detachable. In this embodiment, the retainer ring 3 is in threaded connection with the first aperture section 2b, so that the optical lens 4 is convenient to disassemble, and the structure is simple.
In some embodiments, as shown in fig. 1, the optic 4 holder further comprises a spacer 5, the spacer 5 being adapted to be disposed between the optic 4 and the collar 3 and the step 2 d.
Because the step 2d and the retainer ring 3 are both made of hard materials, and the optical lens 4 is made of fragile materials, the gasket 5 is arranged between the optical lens 4 and the retainer ring 3 and the step 2d to avoid the optical lens 4 from being broken in the process of fixing the optical lens 4 on the adjusting seat 2.
In some embodiments, as shown in FIG. 1, the securing structure includes a bolt 6, and the mounting block 1 and the adjustment block 2 each include a threaded bore, the bolt 6 threadedly engaging the threaded bore to secure the adjustment block 2 to the mounting block 1.
The adjusting seat 2 is fixed on the mounting seat 1 through the bolt 6, so that the first optical hole is convenient to disassemble and adjust the included angle between the central line of the first optical hole and the central line of the second optical hole 1 a.
According to a second aspect of the utility model, the utility model also provides an optical device comprising an optical mirror 4 and an optical mirror 4 holder as in any of the embodiments above. Since the optical device includes the optical lens 4 frame according to any of the embodiments, the optical device has any effect of the optical lens 4 frame, and details thereof are not repeated herein.
According to a third aspect of the present invention, there is also provided a laser system comprising a laser and an optical device as in the above embodiments. Since the laser system includes the optical device, the same technical effects as those of the optical device are obtained.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the utility model and are not to be construed as limiting the utility model. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
