Abstract
Description
Technical Field
[0001] This utility model relates to the field of optics, and in particular to a lens assembly. Background Technology
[0002] A lens is a transparent optical element designed based on the principle of light refraction. It achieves functions such as focusing, imaging, and beam control by controlling the propagation path of light, and is a core component of an optical system.
[0003] The focusing function of a lens is based on the law of refraction in geometric optics. By rationally designing the surface curvature, material refractive index, and optical path structure of the lens, incident parallel light, divergent light, or non-uniform beams can be focused into a high-energy-density focal region.
[0004] Currently, although existing lenses can achieve the effect of refraction and light focusing to a certain extent, since lenses can often only refract light to one side, multiple lenses are often needed to be evenly distributed around the light source when light focusing is required in practice. Therefore, it is quite troublesome to use and arrange them. To address this issue, a lens assembly is proposed. Utility Model Content

[0011] As a further description of the above technical solution:
[0012] The number of focusing teeth is set to multiple, and the number of focusing teeth is even. The focusing teeth are symmetrically arranged with the middle surface of the ring mirror in the vertical direction.
[0013] As a further description of the above technical solution:
[0014] The side of the focusing tooth near the center of the annular mirror is set as a horizontal plane, and both the annular mirror and the focusing tooth are colorless and transparent.
[0015] As a further description of the above technical solution:

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a lens assembly, including a track 1. A lens mechanism 2 is disposed at the upper end of the track 1. An adjustment mechanism 3 is disposed at the bottom end of the lens mechanism 2 and above the track 1. The adjustment mechanism 3 is used to adjust the position of the lens mechanism 2 relative to the track 1. The lens mechanism 2 includes a ring mirror 21. A focusing tooth 22 is fixedly connected to the outer side of the ring mirror 21. The number of focusing teeth 22 is set to multiple and is even. The focusing teeth 22 and the middle surface of the ring mirror 21 in the vertical direction are symmetrically arranged. The ring mirror 21 and the focusing teeth 22 are both colorless and transparent. A fixing block 23 is fixedly connected to the bottom and top of the ring mirror 21. The ring mirror 21, the focusing teeth 22 and the fixing block 23 are integrated. In the molding setup, the materials of the annular mirror 21 and the focusing teeth 22 are glass or plexiglass. The side of the focusing teeth 22 near the middle of the annular mirror 21 is set as a horizontal surface, and the outer side of the annular mirror 21 is set as an arc surface. The curvature of the outer arc surface of the annular mirror 21 is consistent with the curvature of the outer arc surface of the focusing teeth 22. That is, on the cross-section of the annular mirror 21 and the focusing teeth 22, the lines corresponding to the horizontal surface of the focusing teeth 22 are used as auxiliary lines. The middle focusing teeth 22 or the annular mirror 21 is moved horizontally towards the side near the outer arc surface. After the outer arc surface of the focusing teeth 22 adjacent to the outermost one moves to the position where it contacts the plane of the outermost focusing teeth 22, the outer arc surfaces of the two focusing teeth 22 at both ends can just form a complete arc surface. The inner side of the cross-section of the annular mirror 21 is vertical.
[0034] Reference Figures 1-3 The adjustment mechanism 3 includes a sliding seat 31, the inner wall of which is slidably connected to the outer wall of the track 1. A fixed seat 32 is fixedly connected to the top of the sliding seat 31. The fixed seat 32 is cylindrical, and its inner wall has a columnar groove that is not cylindrical. A placement frame 37 is fixedly connected to the top of the sliding seat 31 outside the fixed seat 32. The placement frame 37 is cylindrical, and its top has a protrusion with a concave cross-section. The shape of the placement frame 37 ensures that the lens mechanism 2 can place the fixed block 23 on the concave protrusion of the placement frame 37. The recessed area of the slide rail fixes the lens mechanism 2. A slide bar 33 is slidably connected to the inner wall of the mounting base 32. The slide bar 33 slides up and down. The bottom end of the slide bar 33 has a protrusion that fits the shape of the inner wall of the mounting base 32. The protrusion ensures that when the slide bar 33 rotates, the groove at the bottom end of the slide bar 33 can push the groove of the inner wall of the mounting base 32, thereby pushing the mounting base 32. A mounting plate 34 is fixedly connected to the top end of the slide bar 33. A clamp 35 for mounting the light source is fixedly connected to the top end of the mounting plate 34. The clamp 35 is set on the axis of the mounting bracket 37.
[0035] Reference Figures 1-3The sliding seat 31 and the slide bar 33 are both equipped with a height adjustment component 36. The height adjustment component 36 includes a threaded rod 361. The outer wall of the threaded rod 361 is threadedly connected to the inner wall of the slide bar 33. The inner wall of the slide bar 33 has a threaded groove that matches the shape of the outer wall of the threaded rod 361 and extends through the bottom end of the slide bar 33. The threaded groove ensures that the slide bar 33 can move up and down relative to the threaded rod 361 when the threaded rod 361 rotates. The bottom end of the threaded rod 361 is fixedly connected to a rotating rod 362. The bottom end of the rotating rod 362 is fixedly connected to a bevel gear 363. The inner wall of the sliding seat 31 is rotatably connected to a rotating bar 364. The rear end of the rotating bar 364 is fixedly connected to a bevel gear 365. The bevel gear 363 and the bevel gear 365 mesh. The front end of the rotating bar 364 is fixedly connected to a knob 366. The knob 366 has anti-slip texture on its outer side.
[0036] Working principle: When in use, the operator first fixes the light source above the mounting plate 34 using the clamp 35, then places the lens mechanism 2 above the mounting frame 37, and makes the fixing block 23 in the recessed position at the top of the mounting frame 37.
[0037] Once the placement is complete, the staff turns knob 366.
[0038] When knob 366 is turned, rotating bar 364 rotates along with knob 366, causing bevel gear 365 to rotate under the drive of rotating bar 364. Since bevel gear 363 meshes with bevel gear 365, bevel gear 363 is driven to rotate during the rotation of bevel gear 365, thereby causing rotating rod 362 to rotate.
[0039] When the rotating rod 362 rotates, the threaded rod 361 rotates accordingly. At this time, because the outside of the slide bar 33 is limited by the fixed seat 32, it cannot rotate with the threaded rod 361. Therefore, when the threaded rod 361 rotates, it moves up and down, which drives the mounting plate 34 to move up and down. As a result, the light source fixed by the clamp 35 moves up and down accordingly.
[0040] When the light source is adjusted to the middle position of the ring mirror 21, after being refracted by the ring mirror 21 and the focusing tooth 22, the light source emitted towards the outside is refracted horizontally to the outside of the ring mirror 21, thus causing the emitted light source to converge and be emitted horizontally to the outside.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
