Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] To address the reliability issues and inconvenience of disassembly in traditional adhesive-based fixing methods, this invention provides a locking structure based on an optical lens. The structure includes a mounting base, a clamping component, and a connector. The mounting base is sleeved and positioned outside the target lens, serving as a mounting platform for the clamping component. The clamping component is detachably mounted on the mounting base. An arched section in the middle of the clamping component forms a clamping space between the clamping component and the mounting base. The connector's fixing section is fixedly connected to the target lens. During focusing, the clamping section of the connector extends into the clamping space and moves within it following the focusing motion of the target lens. After focusing, the clamping component is fixed, securing the clamping section of the connector within the clamping space, thus maintaining the target lens's focus. This locking structure uses a mechanical fixing method to secure the lens, making it less susceptible to environmental influences, highly reliable, and easy to disassemble and replace the lens.

[0022] Specifically, such as Figures 1 to 3 As shown, the locking structure of this embodiment features a sleeve-type mounting base 210 for fitting and positioning outside the lens 100. A clamping member 220 is detachably attached to the side wall of the mounting base 210, and the middle section of the clamping member 220 includes an arched section, forming a clamping space 201 between the side wall of the mounting base 210 and the clamping member 220. The fixing section 231 of the connector 230 is fixedly connected to the lens 100, and the clamping section 232 extends into the clamping space 201. By controlling the tightness between the clamping member 220 and the mounting base 210, the clamping and fixing state of the clamping section 232 can be controlled.

[0023] Before focusing the lens 100 onto the focusing object (such as the host of an image acquisition device, where the focus of the lens 100 needs to fall on the device sensor so that the sensor can acquire a clear image), the mounting base 100 is fixed to the focusing object via the flange 212, and the lens 100 is pre-assembled and positioned with the locking structure. At this time, the clamping section 232 of the connector 230 is pre-positioned in the clamping space 201, and the lens 100 is adjusted axially to focus until the photosensitive device can obtain a clear image through the lens 100. At the same time, the clamping section 232 can move linearly in the clamping space 201, synchronously maintaining the axial attitude of the lens 100, reducing the risk of optical axis misalignment, and improving focusing reliability.

[0024] After focusing is complete, tightening the clamping member 220 will fix the clamping section 232 of the connector 230, thereby fixing the lens 100 to the photosensitive device through the locking structure and fixing the focusing state.

[0025] To improve the fixing effect of the connector 230, the clamping section 232 of the connector 230 is fitted and matched with at least one of the clamping member 220 and the mounting base 210, increasing the contact area and thus improving the clamping and fixing effect. For example, in this embodiment, the top surface of the clamping section 232 and the inner surface of the arched section of the clamping member 220 are fitted and matched with each other.

[0026] The connector 230 is pre-fixed on the lens 100. To facilitate the docking of the lens 100 and the mounting base 210, the width of the clamping section 232 is smaller than the arc length of the clamping space 201, which can avoid the positioning of the connector 230 and the clamping space 201 in the circumferential direction and facilitate operation.

[0027] Specifically, the curvature of the clamping space 201 is π / 3 to 5π / 9, and the curvature of the clamping member 220 is 2π / 3 to π. This satisfies the need for convenient docking operation between the connector 230 and the clamping space 201, while also taking into account the docking length between the clamping member 220 and the mounting base 210, ensuring the fixed reliability between the clamping member 220 and the mounting base 210.

[0028] To ensure the reliability of the clamping and fixing of the connector 230, in this embodiment, the length of the clamping segment 232 satisfies: L≥d0+d1+1.0mm, where L is the length of the clamping segment 232, d0 is the focusing range of the target lens, and d1 is the effective width of the clamping space (when there is no chamfer on the contact edge, it is consistent with the width of the clamping member 220). This ensures that the contact area between the clamping segment 232 and the clamping member 220 is maximized under any focusing state, thus ensuring the clamping and fixing effect. The 1.0mm redundant length facilitates processing.

[0029] The outer diameter of the lens 100 is generally relatively uniform. The mating surfaces of the clamping member 230 and the mounting base 210 are located on the outer side, that is, the mounting base 210 can form a stepped structure on the lens 100. In order to facilitate the docking of the clamping member 230 with the stepped structure, in this embodiment, there is a step difference between the fixed section 231 and the clamping section 232 of the connecting member 230. Specifically, in this embodiment, it is a vertical step difference. The focusing range of the lens 100 can be limited by the limiting between the connecting section of the vertical step difference and the end face of the mounting base 210 to avoid over-adjustment.

[0030] To facilitate the fit between the top surface of the clamping section 232 and the inner surface of the arched section of the clamping member 220, a chamfer is provided on the side edge of the clamping section 232. The clamping section 232 protrudes outward, and the chamfer also improves safety and avoids injury to workers from sharp edges.

[0031] To facilitate the connection between the clamping member 220 and the mounting base 210, in this embodiment, the clamping member 220 and the mounting base 210 are fixed together by bolts, and the clamping member 220 is provided with a waist hole 221 for bolt installation.

[0032] For ease of installation, in this embodiment, as follows: Figure 2 As shown, the mounting base 210 is provided with a plurality of first mounting holes 211, which are evenly spaced along the circumference of the mounting base 210 and are aligned with the waist holes 221 of the clamping member 220. By providing a plurality of first mounting holes 211, the requirement for installation direction can be reduced during installation, thereby improving the ease of operation.

[0033] This utility model also provides an optical lens, on the outer wall of which is provided a docking structure matching the locking structure of the optical lens, for installing the locking structure. It can be fixed after focusing by mechanical fixing, with high fixing reliability, easy disassembly, and wide applicability.

[0034] Specifically, such as Figure 1 As shown, the docking structure includes multiple second mounting holes 101, which are spaced apart along the circumference of the lens 100. The fixing section 231 of the connector 230 is screwed to the lens 100 through the second mounting holes 101. Multiple mounting holes can be used for redundancy to avoid the problem of unusability due to damage to a single mounting hole.

[0035] The system includes multiple first mounting holes 211 and second mounting holes 101, and can also support two sets of clamping members 220 and connecting members 230, which can further improve the fixation reliability and can be symmetrically arranged to assist in the positioning and fixation of the optical axis attitude of the lens 100. Specifically, eight or more first mounting holes 211 and second mounting holes 101 can be provided.

[0036] This utility model provides a locking structure and optical lens based on an optical lens, including a mounting base, a clamping member, and a connecting member. The mounting base is sleeved and positioned outside the target lens, serving as a mounting platform for the clamping member. The clamping member is detachably mounted on the mounting base. An arched section in the middle of the clamping member forms a clamping space between the clamping member and the mounting base. The fixing section of the connecting member is fixedly connected to the target lens. During focusing, the clamping section of the connecting member extends into the clamping space and moves within the clamping space following the focusing action of the target lens. After focusing, the clamping member is fixed, securing the clamping section of the connecting member within the clamping space, thus fixing the focus state of the target lens. This mechanical lens fixing method is less susceptible to environmental influences, offers high reliability, facilitates lens disassembly and replacement, and has a wide range of applications.
