[0002] The UV galvanometer is a special optical mirror. Compared with the ordinary galvanometer, the difference is that the galvanometer can be applied to a wider optical range, while the UV galvanometer is a special optical element specially used to process ultraviolet light. UV galvanometers are mainly used in ultraviolet lasers, detection instruments, spectrometers, medical equipment, semiconductor manufacturing and other fields.

[0003] After searching, the patent with the authorization announcement number CN208721890U discloses a laser scanning galvanometer.

The field lens is directly assembled at the bottom of the galvanometer assembly and is detachably connected to the galvanometer assembly, which is easy to operate. The embedded field lens is designed with multiple specifications, covering multiple formats, and can be assembled arbitrarily, so as to realize the marking requirements of different formats, which is convenient for users to use. In addition, two red light assemblies are arranged at the bottom of the galvanometer assembly. Two beams of red light will generate two light spots when irradiated on the surface of the marking part. The two light spots are adjusted to coincide, and the coincidence point of the two light spots is set at the focal length of the field lens. In this way, the focal length and marking working distance of the laser scanning galvanometer can be found quickly and easily, which is convenient for users to use.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 7 A supported and stable ultraviolet galvanometer comprises a galvanometer body 1 located on one side of a bracket 4, a connecting plate 2 is fixedly connected to the side of the galvanometer body 1 close to the bracket 4, a flange is fixedly connected to the side of the bracket 4 close to the galvanometer body 1, a connecting pipe 7 is fixedly connected to the side of the connecting plate 2 away from the galvanometer body 1, a plurality of supporting plates 8 are fixedly connected to the outer wall of the other end of the connecting pipe 7, and vertical grooves 801 are penetrated on the surfaces of the plurality of supporting plates 8, the outer wall of the connecting pipe 7 is connected to a limiting component and a lifting component, the limiting component is located on the side close to the galvanometer body 1, and the lifting component is connected to the limiting component on the side close to the galvanometer body 1, the other side of the lifting component penetrates the plurality of vertical grooves 801 and is connected to a plurality of moving plates 9, the other sides of the plurality of moving plates 9 are fixedly connected to a plurality of threaded rods 10, the other ends of the plurality of threaded rods 10 penetrate the flange of the bracket 4, and the flange of the bracket 4 is clamped in the middle by nuts.

[0024] The supported and stable ultraviolet galvanometer in the utility model is similar to the existing ultraviolet galvanometer structure, such as a laser scanning galvanometer disclosed in the patent with publication number CN208721890U. The main improvement of the utility model is that when the user connects the galvanometer body 1 with the bracket 4, if the size of the flange of the galvanometer body 1 and the bracket 4 is not suitable, the height of the plurality of movable plates 9 and the threaded rod 10 can be changed through the limit assembly and the lifting assembly to match the flanges of different sizes, so that the galvanometer body 1 can be connected more stably under the support of the bracket 4. Figures 1 to 7 As shown, when the supported and stable ultraviolet galvanometer in the utility model is in use, first align the connecting tube 7 on the connecting plate 2 on one side of the galvanometer body 1 with the inner wall of the bracket 4 and insert it. After insertion, if it is found that the threaded rods 10 on the movable plates 9 cannot be aligned with the hole positions of the flange on the bracket 4, the limiting assembly can be loosened first to allow the lifting assembly to rotate. Then, one hand holds the limiting assembly and the other hand rotates the lifting assembly. As the lifting assembly rotates, the movable plates 9 and the threaded rods 10 are pushed to open outward, so that flanges of different sizes can be matched. In the process of adjustment, if the distance is appropriate, the threaded rods 10 can be passed through the flange of the bracket 4 through the bracket 4, so that the movable plate 9 and the threaded rods 10 cannot be rotated back. Then, the limiting assembly is used to limit the lifting assembly, the movable plate 9 and the threaded rods 10 again, so that the connectivity between them and the flange of the bracket 4 is more stable, which is convenient and easy to operate.

[0025] Please refer to Figure 1-Figure 7 The lifting assembly includes a rotating plate 6 and a plurality of sliding rods 11. The side of the rotating plate 6 close to the galvanometer body 1 is connected to the limit assembly. The other side of the rotating plate 6 is provided with a plurality of inclined grooves 601. The inner wall of the rotating plate 6 is rotatably connected to the outer wall of the connecting tube 7. One end of the plurality of sliding rods 11 is respectively slidably connected to the inner walls of the plurality of inclined grooves 601. The other ends of the plurality of sliding rods 11 pass through a plurality of vertical grooves 801 and are fixedly connected to the movable plate 9. The plurality of inclined grooves 601 and the plurality of vertical grooves 801 are matched and aligned. The cross sections of the inclined grooves 601 and the vertical grooves 801 are both T-shaped, and the cross section of the sliding rod 11 is I-shaped.

[0026] More specifically, when it is necessary to change the spacing between the movable plate 9 and the threaded rod 10 to accommodate more models of bracket 4 flanges, it is only necessary to rotate the rotating plate 6. After the rotating plate 6 is rotated, because the cross-sections of the plurality of sliding rods 11 are I-shaped, the cross-sections of the inclined grooves 601 and the vertical grooves 801 are both T-shaped, and the plurality of inclined grooves 601 and the plurality of vertical grooves 801 are matched and aligned, when the rotating plate 6 is rotated, the two ends of the sliding rod 11 are squeezed by the inclined grooves 601 and the vertical grooves 801 and can only extend outward, so that the plurality of movable plates 9 and the threaded rods 10 can be expanded outward, thereby changing the height between the movable plate 9 and the threaded rod 10 and the connecting pipe 7 to adapt to bracket 4 flanges of more sizes.

[0027] Please refer to Figure 1-Figure 7 The limiting assembly includes a threaded ring 3 and a plurality of sector blocks 5. The same end of the plurality of sector blocks 5 is fixedly connected to the side of the rotating plate 6 away from the sliding rod 11. The threaded ring 3 is sleeved on the outer wall of the plurality of sector blocks 5 and is threadedly connected to the plurality of sector blocks 5. The cross-sections of the threaded ring 3 and the plurality of sector blocks 5 are both right-angled trapezoids, wherein the end of the plurality of sector blocks 5 close to the rotating plate 6 is a narrower end, and the end of the threaded ring 3 close to the rotating plate 6 is a thicker end.

[0028] More specifically, in the initial stage, when the threaded ring 3 is in an unrestricted state, the thicker end of the threaded ring 3 is threadedly connected to the narrower end surface of the plurality of sector blocks 5, and at this time, the threaded ring 3, the plurality of sector blocks 5, the rotating plate 6, the sliding rod 11, the movable plate 9 and the threaded rod 10 can all rotate around the outer wall of the connecting tube 7; when it is necessary to limit the rotating plate 6, the sliding rod 11, the movable plate 9 and the threaded rod 10, the rotating plate 6 is held by hand to make it aligned with the plurality of sector blocks 5, the plurality of movable plates 9 And the threaded rod 10 cannot rotate, at this time, the threaded ring 3 is rotated alone, and the rotation of the threaded ring 3 is rotated according to the surface threads of the several sector blocks 5. When the thicker end of the threaded ring 3 slowly moves to the thicker end of the several sector blocks 5, the threaded ring 3 will slowly squeeze the inner walls of the several sector blocks 5 toward the outer wall of the connecting pipe 7 until they are squeezed tightly and cannot rotate. After the several sector blocks 5 are squeezed tightly, the rotating plate 6, the sliding rod 11, the movable plate 9 and the threaded rod 10 are all limited and cannot rotate, which is convenient and easy to operate.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
