[0002] Optical lenses have a wide range of applications, including those in lighting equipment. Optical lenses can enable lighting equipment to project light further or over a wider area. However, most existing lighting equipment uses a single lens structure, which can only achieve a fixed focusing or flooding effect and cannot be dynamically adjusted according to the usage scenario. For example, equipment with only convex lenses has a limited focusing range, while equipment with only concave lenses struggles to achieve long-distance lighting, exhibiting limited functionality and poor adaptability. In view of this, the inventors have made a new invention. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a combined optical lens structure that can be adjusted by finger push and rotation. This structure has the advantages of simple operation, stepless adjustment, and effective light focusing and dispersion.

Both the first and second components are cylindrical. The first component, from the outside to the inside, is provided with a shell, a connecting shell, and a concave lens component. A positioning ring is provided on the outside of one end of the connecting shell. The second component, from the outside to the inside, is provided with a rotating seat, an aluminum shell, and a convex lens component. A gap is formed between the rotating seat and the aluminum shell to form a connecting groove that can accommodate the connecting shell. A side groove is provided on the inner wall of the rotating seat, and the positioning ring can move within the side groove. A threaded portion is provided within the side groove, and a first notch and a second notch are provided at the upper and lower ends of the threaded portion, respectively. One end of the second component is provided with several strip-shaped protrusions surrounding the bottom of the rotating seat and a groove formed by the cooperation of the rotating seat and the convex lens component.
[0005] Furthermore, the concave lens component is a plano-concave lens structure, with the plane of the concave lens component extending outside the first component.
[0006] Furthermore, the convex lens component is a plano-convex lens, with one side of the convex surface of the convex lens component facing the concave surface of the concave lens component.
[0007] Furthermore, the inner wall of the aluminum shell is provided with a polished layer.
[0008] Furthermore, the outer wall of the rotating seat is provided with several strip grooves.
[0009] Beneficial Effects: Compared with the prior art, the present invention provides a combined optical lens structure for finger-push rotation adjustment, comprising a first component and a second component. The first component is provided with a shell, a connecting shell, and a concave lens component. The connecting shell is provided with a positioning ring. The second component is provided with a rotating seat, an aluminum shell, and a convex lens component. A gap is formed between the rotating seat and the aluminum shell to form a connecting groove that can accommodate the connecting shell.

Detailed Implementation
[0015] The following is in conjunction with the appendix Figures 1 to 3 This utility model will be described in detail.
[0016] This utility model discloses a combined optical lens structure with finger-push rotation adjustment, comprising a first component 1 and a second component 2, both of which are cylindrical. The first component 1 is provided with a shell 11, a connecting shell 12, and a concave lens component 3 in sequence from the outside to the inside. A positioning ring 13 is provided on the outside of one end of the connecting shell 12. The second component 2 is provided with a rotating seat 21, an aluminum shell 22, and a convex lens component in sequence from the outside to the inside. A gap is formed between the rotating seat 21 and the aluminum shell 22 to form a connecting groove 23 that can accommodate the connecting shell 12. A side groove 24 is provided on the inner wall of the rotating seat 21, and the positioning ring 13 can move in the side groove 24. A threaded part 241 is provided in the side groove 24. A first notch 242 and a second notch 243 are provided at the upper and lower ends of the threaded part 241, respectively. The positioning ring 13 can be connected to the threaded part 241. The connecting shell 12 is inserted into the connecting groove 23, so that the first component 1 and the second component 2 are movably connected. The second component 2 has several strip-shaped protrusions 25 surrounding the bottom of the rotating base 21, and a groove 26 formed by the rotating base 21 and the convex lens part 4. The first component 1 is installed on a light source device such as a flashlight or searchlight. The second component 2 can be rotated by pressing the strip-shaped protrusions 25 with a finger, which changes the relative position of the convex lens part 4 and the concave lens part 3, thereby changing the light diffusion and focusing effect. Specifically, according to optical principles, the curvature and size of the concave lens part 3 and the convex lens part 4 are adjusted so that the virtual focal point of the concave lens part 3 coincides with the real focal point of the convex lens part 4. At this time, the positioning ring 13 is located in the middle of the threaded part 241. The light emitted by the light source device is diffused by the concave lens part 3 and then refracted by the convex lens part 4 to restore it to parallel light, and the light is not focused or diffused. Rotating the second component 2 forward increases the distance between the convex lens 4 and the concave lens 3, causing the light to diverge through the concave lens 3. At this point, the light received by the convex lens 4 is far from its focal point. Therefore, under this action, the light emitted by the light source device is diffused, allowing it to illuminate a larger area. Rotating the second component in the reverse direction causes the light from the light source device to diverge after entering the convex lens 4, but the divergence does not exceed the converging capability of the convex lens 4. The convex lens 4 then refocuses the light, causing the light emitted by the light source device to be focused, thus improving the brightness and illumination distance. The user can easily and quickly adjust the light convergence and divergence effect by rotating the second component 2 with their finger. The width of the first notch 242 and the second notch 243 is greater than or equal to the width of the positioning ring 13. After the second component 2 rotates a certain number of times, the positioning ring 13 will disengage from the threaded part 241 and enter the first notch 242 or the second notch 243. The first notch 242 and the second notch 243 can allow the positioning ring 13 to rotate freely. Even if the second component 2 rotates excessively, it will not jam, preventing the first component 1 and the second component 2 from jamming each other. It is safe and stable during use.
[0017] The first component 1 is installed after the light source device. The flat portion of the concave lens component 3 extends into the light source device and faces the direction from which the light from the light source device is emitted. Therefore, the area of the flat portion of the concave lens component 3 may be smaller than the area of light emission. Considering this, in this solution, the concave lens component 3 is a plano-concave lens structure, with the flat portion of the concave lens component 3 extending outside the first component 1. This has two advantages: firstly, it can reduce the volume of the outer casing 11, thereby reducing the overall thickness of the first component 1; secondly, it can collect a larger range of light, improving light transmission performance.
[0018] The four convex lens components are plano-convex lenses, with one side of the convex surface of each component facing the concave surface of the concave lens component 3. Light passes through the convex surface of the four convex lens components and is then refracted out by the planar surface of the four convex lens components. Combined with the groove 26 formed by the rotation seat 21 and the four convex lens components, the circumferential astigmatism effect can be reduced, preventing light from scattering from the side and irritating the vision of the user or people in the vicinity.
[0019] The inner wall of the aluminum shell 22 is provided with a polished layer. The aluminum shell 22 is cylindrical and is used to prevent light from escaping into the rotating seat 21 or from the gap between the first component 1 and the second component 2. The polished layer can increase the light refractive index of the inner wall of the aluminum shell 22 and reduce the light source loss.
[0020] The outer wall of the rotating base 21 is provided with several strip grooves 27. The strip grooves 27 can provide a certain anti-slip performance for the outside of the rotating base 21. Under certain circumstances, the user can rotate the second component 2 by holding the outside of the rotating base 21, which is highly convenient to use.
[0021] The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this invention, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. 。
