Detailed Embodiment

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0021] AsFigures 1-9 As shown in the figure, an optical lens proposed in this embodiment includes a camera 1. A lens holder 2 is clamped to the outer wall of the camera 1. A uniformly distributed clamping plate 10 is fixedly connected to the outer wall of the lens holder 2. The clamping plate 10 is clamped with an adapter ring 4 through a clamping block 9. The adapter ring 4 realizes the adapter requirements of the camera 1 for different optical lens bodies 6. The adapter ring 4 is connected to the optical lens body 6 through a temperature drift self-adaptive calibration component. The optical lens body 6 is a fixed-focus lens. The best imaging effect is achieved through the thread adjustment between the adapter ring 4 and the optical lens body 6. Uniformly distributed sliding grooves 13 are formed in the outer wall of the lens holder 2. It also includes: A retractable protection component. The retractable protection component includes a fixed shield 5, a transmission shield 17 and an extension shield 18 arranged on the outer wall of the adapter ring 4. The fixed shield 5 is threadedly connected to the adapter ring 4. Uniformly distributed guide grooves 20 are formed in the outer walls of the transmission shield 17 and the extension shield 18. Uniformly distributed positioning holes 22 are formed in the outer walls of the transmission shield 17 and the extension shield 18. The retractable protection component plays a role in protecting and buffering when the lens drops, reducing direct damage to the lens. The protection component is threadedly connected to the adapter ring 4 through the fixed shield 5, which is convenient for disassembly and replacement and reduces the maintenance cost; A positioning component, which is arranged on the outer wall of the strong spring B24 and cooperates with the retractable protection component; A locking and anti-dropping component, which is arranged on the inner wall of the sliding groove 13.

[0022] As Figure 9As shown, as a preferred embodiment, on the basis of the above method, further, the temperature drift adaptive calibration component includes a T-shaped block 27 symmetrically and slidably connected to the outer wall of the adapter ring 4. A docking ring 25 is fixedly connected to the outer wall of the T-shaped block 27, and the docking ring 25 is threadedly connected to the optical lens body 6. Symmetrically distributed shape memory alloy brackets 28 are fixedly connected to the outer wall of the docking ring 25. One end of the shape memory alloy bracket 28 away from the docking ring 25 is fixedly connected to a heat conduction rod 29. A heat insulation cover 31 is fixedly connected to the outer wall of the heat conduction rod 29. A heating ring 32 is fixedly connected to the inner wall of the heat insulation cover 31, and the heating ring 32 is fixedly connected to the heat conduction rod 29. Evenly distributed extrusion rods 30 are fixedly connected to the outer wall of the heat insulation cover 31, and one end of the extrusion rod 30 away from the heat insulation cover 31 abuts against the outer wall of the pressure receiving ring 26. A control chip 33 is fixedly connected to the outer wall of the heat insulation cover 31, and the outer wall of the control chip 33 is electrically connected to the heating ring 32. When the ambient temperature changes, the shape memory alloy bracket 28 deforms adaptively according to the temperature change, thereby adjusting the position of the docking ring 25, that is, adjusting the position of the optical lens body 6. If the adaptive position is improper, the control chip 33 automatically starts the heating ring 32 according to the preset program. The heat generated by the heating ring 32 is transmitted to the shape memory alloy bracket 28 through the heat conduction rod 29. The shape memory alloy bracket 28 will deform with the temperature change, driving the docking ring 25 to slide along the T-shaped block 27, thereby finely adjusting the position of the optical lens body 6. At the same time, the heat insulation cover 31 reduces heat dissipation and prevents the heat energy generated from affecting the optical imaging inside the lens, ensuring that the heat energy effectively acts on the shape memory alloy bracket 28. The cooperation between the extrusion rod 30 and the pressure receiving ring 26 limits the heat transfer range, making the adjustment process more precise.

[0023] As Figures 7-8 shown, as a preferred embodiment, on the basis of the above method, further, the positioning component includes a strong spring B24 fixedly connected to the outer walls of the fixed shield 5 and the transmission shield 17 evenly. A positioning ball 23 is fixedly connected to the outer wall of the strong spring B24, and the positioning ball 23 is located inside the positioning hole 22. The positioning ball 23 is stuck into the positioning holes 22 at different positions under the action of the strong spring B24, realizing the telescopic positioning of the protection component.

[0024] As Figure 6 shown, as a preferred embodiment, on the basis of the above method, further, the locking and anti-dropping component includes a slider 14 slidably connected to the inner wall of the chute 13. A lock ring 3 is fixedly connected to the outer wall of the slider 14. Evenly distributed extrusion blocks 12 are fixedly connected to the outer wall of the lock ring 3. Evenly distributed conical push blocks 16 are fixedly connected to the outer wall of the lock ring 3. The conical push blocks 16 have strong friction, which is convenient for pushing the lock ring 3 to move, thereby facilitating the disassembly of the adapter ring 4.

[0025] As Figure 6As shown, as a preferred embodiment, on the basis of the above method, further, a strong spring A15 is fixedly connected to the outer wall of the slider 14, and one end of the strong spring A15 away from the slider 14 is fixedly connected to the chute 13. The elastic force of the strong spring A15 can push the slider 14 to drive the lock ring 3 to always move towards the clamping plate 10, that is, the extrusion block 12 always extrudes the convex block 11 to prevent the clamping plate 10 from moving, thereby realizing the locking effect on the clamping block 9.

[0026] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a triangular groove 8 is provided between the lens holder 2 and the clamping plate 10, and the triangular groove 8 provides a movable space for the clamping plate 10.

[0027] As Figure 2 shown, as a preferred embodiment, on the basis of the above method, further, a pressure-receiving ring 26 is fixedly connected to the inner wall of the lens holder 2, a photosensitive film 7 is fixedly connected to the outer wall of the pressure-receiving ring 26, and the photosensitive film 7 is used in cooperation with the optical lens body 6. After the optical lens body 6 refracts, an image is focused on the surface of the photosensitive film 7, and the photosensitive element converts the optical signal into an electrical signal and transmits it to the image processor.

[0028] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, a light-shielding cover 19 is threadedly connected to the outer wall of the extension shield 18. The light-shielding cover 19 is used to reduce the entry of stray light into the lens. The light-shielding cover 19 can reduce the entry of stray light into the lens and improve the imaging quality.

[0029] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, uniformly distributed guide blocks 21 are fixedly connected to the outer walls of the transmission shield 17 and the fixed shield 5, and the guide blocks 21 are slidably connected to the guide grooves 20. The transmission shield 17 and the extension shield 18 are slidably connected through the guide blocks 21 and the guide grooves 20. When it is necessary to adapt to lenses of different lengths, the extension of each shield is realized by the sliding of the guide blocks 21 in the guide grooves 20.

[0030] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a convex block 11 is fixedly connected to the outer wall of the clamping plate 10, and the outer wall of the convex block 11 abuts against the outer wall of the extrusion block 12.

[0031] Specifically, when this optical lens is in use: The lens mount 2 is quickly snap-connected to the adapter ring 4 through the clamping plate 10 and the clamping block 9. During installation, align the clamping plate 10 with the card slot of the adapter ring 4 and rotate it. The clamping block 9 snaps into the card slot to complete the preliminary connection. Subsequently, under the action of the strong spring A15, the locking ring 3 slides upward, driving the extrusion block 12 to squeeze the protruding block 11 on the clamping plate 10, so that the clamping plate 10 further clamps the adapter ring 4. At the same time, the conical push block 16 prevents the clamping plate 10 from moving in the reverse direction, realizing the anti-detachment function. When disassembling, only need to push the conical push block 16 to drive the locking ring 3 to slide in the chute 13 through the slider 14, and then pull out the adapter ring 4 with force; The fixed shield 5 is threadedly connected to the adapter ring 4. The transmission shield 17 and the extension shield 18 are slidably connected through the guide block 21 and the guide groove 20. When it is necessary to adapt to lenses of different lengths, pull the extension shield 18, and the positioning ball 23 snaps into the positioning holes 22 at different positions under the action of the strong spring B24, realizing the telescopic positioning of the protection component; The telescopic protection component plays a role in protecting and buffering when the lens drops, reducing direct damage to the lens. The light shield 19 can reduce stray light from entering the lens and improve the imaging quality. The protection component is threadedly connected to the adapter ring 4 through the fixed shield 5, which is convenient for disassembly and replacement and reduces the maintenance cost; When the ambient temperature changes, the shape memory alloy bracket 28 deforms adaptively according to the temperature change, thereby adjusting the position of the docking ring 25, that is, adjusting the position of the optical lens body 6. If the adaptive position is improper, its control chip 33 automatically starts the heating ring 32 according to the preset program. The heat generated by the heating ring 32 is transmitted to the shape memory alloy bracket 28 through the heat conduction rod 29. The shape memory alloy bracket 28 will deform with the temperature change, driving the docking ring 25 to slide along the T-shaped block 27, thereby finely adjusting the position of the optical lens body 6. At the same time, the heat insulation cover 31 reduces heat dissipation and prevents the heat energy from affecting the optical imaging inside the lens, ensuring that the heat energy acts effectively on the shape memory alloy bracket 28. The cooperation of the extrusion rod 30 and the compression ring 26 limits the heat transfer range, making the adjustment process more accurate.
