[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] Please see Figure 1-7 This utility model provides a technical solution:

[0034] An optical lens with a quick-release mechanism includes:

[0035] Mounting base 1 has a plurality of first limiting holes 101 arranged in a ring on its side wall. A fixed lens 2 is fixedly connected inside the mounting base 1. A mounting cylinder 3 is threadedly connected inside the mounting base 1. A sealing cover 4 is threadedly connected to the end of the mounting cylinder 3. A plurality of second limiting holes 401 are arranged in a ring on the side wall of the sealing cover 4. A protective lens 5 is fixedly connected inside the sealing cover 4. Limiting components 6 are provided on the outside of the mounting cylinder 3 for limiting the mounting base 1 and the sealing cover 4 respectively.

[0036] The mounting cylinder 3 is fixedly connected to a fixing plate 7, and is slidably connected to multiple lenses 9. It is also slidably connected to a focusing lens 12. The mounting cylinder 3 is equipped with a mounting assembly that facilitates the removal of the multiple lenses 9 and the focusing lens 12.

[0037] The mounting cylinder 3 is equipped with a moving component 13 for adjusting the position of the focusing lens 12.

[0038] It is worth noting that the mounting base 1, as the basic support component of the entire optical lens, plays a crucial role. The multiple first limiting holes 101 can perfectly cooperate with the limiting component 6 to achieve a reliable limiting function. The fixed lens 2 is made of high-quality optical materials, with accurate optical parameters and good optical performance, which can provide a stable basic optical effect for the entire optical lens. At the same time, the mounting base 1 has a mounting cylinder 3 installed inside by means of threaded connection. This threaded connection method not only ensures the firmness of the installation, but also facilitates disassembly when needed, providing convenience for subsequent maintenance and replacement of parts.

[0039] Mounting cylinder 3 is one of the core components of the optical lens. It undertakes the important task of mounting and accommodating multiple optical elements. The end of mounting cylinder 3 is connected to a sealing cap 4 by a thread. This threaded connection is tight and reliable, which can effectively prevent external dust, moisture and other impurities from entering the lens and protect the internal optical elements from damage. Multiple second limiting holes 401 correspond to the first limiting holes 101 and cooperate with the limiting component 6 to limit and fix the mounting base 1 and the sealing cap 4. The protective lens 5 is made of high-strength transparent material, which can protect the internal optical elements without affecting the normal transmission of light and ensure the imaging quality of the optical lens. Through the function of the limiting component 6, the connection between mounting cylinder 3, mounting base 1 and sealing cap 4 can be ensured to be stable and reliable, and there will be no loosening or displacement during use.

[0040] The fixing plate 7 provides a stable support frame for the entire internal structure. The fixing plate 7 has a light-passing hole inside to facilitate lens imaging. These lenses 9 are key components for the optical lens to achieve imaging function. Through precise optical design and arrangement, they can refract and focus light to form a clear image. The position of the focusing lens 12 can be adjusted according to actual use needs to achieve different focusing effects. In order to facilitate the removal of multiple lenses 9 and focusing lens 12, the mounting cylinder 3 is equipped with mounting components inside.

[0041] The limiting component 6 includes a fixed ring 61, an elastic rod 62, a movable ring 63, and a limiting rod 64;

[0042] Multiple elastic rods 62 are fixedly connected to the side walls of the two fixed rings 61 in a ring shape. A movable ring 63 is fixedly connected to the side walls of the multiple elastic rods 62. The two movable rings 63 are slidably connected to the mounting cylinder 3. Limiting rods 64 are fixedly connected to the side walls of the two movable rings 63. The multiple limiting rods 64 are slidably connected to multiple first limiting holes 101 and multiple second limiting holes 401.

[0043] Furthermore, the two fixing rings 61 are respectively fixed at appropriate positions on the outside of the mounting cylinder 3 to provide fixed support points for the entire limiting assembly 6. These elastic rods 62 are made of a material with good elasticity, which can undergo elastic deformation when subjected to external force and quickly return to their original shape after the external force disappears. Two movable rings 63 are slidably connected to the mounting cylinder 3, allowing the movable rings 63 to slide freely on the mounting cylinder 3. Multiple limiting rods 64 are slidably connected to multiple first limiting holes 101 and multiple second limiting holes 401. When it is necessary to install or fix the mounting cylinder 3, the mounting base 1, and the sealing cover 4, the movable rings 63 are pushed to compress the elastic rods 62, aligning the limiting rods 64 with the corresponding first limiting holes 101 or second limiting holes 401. Then the movable rings 63 are released, and under the elastic force of the elastic rods 62, the limiting rods 64 are inserted into the corresponding limiting holes, thereby achieving the purpose of limiting and fixing. When it is necessary to disassemble, the movable rings 63 are pushed again to pull the limiting rods 64 out of the limiting holes, thus releasing the limiting, which is convenient and quick.

[0044] The mounting components include mounting arc 10 and moving bar 11;

[0045] The mounting cylinder 3 has two symmetrically distributed mounting arcs 10 that slide inside. The two mounting arcs 10 contact the mounting base 1 and the sealing cover 4 respectively. Multiple moving strips 11 are fixedly connected to the side walls of the two mounting arcs 10 in a ring. The multiple moving strips 11 are all made of rubber and are slidably connected to the mounting cylinder 3 and the focusing lens 12 respectively. The multiple moving strips 11 are also bonded to multiple lenses 9 respectively.

[0046] Specifically, the mounting cylinder 3 has two symmetrically distributed mounting arcs 10 that slide inside. These two mounting arcs 10 contact the mounting base 1 and the sealing cover 4 respectively, serving as positioning and support functions. The multiple moving strips 11 are all made of rubber. The rubber material has good flexibility and elasticity, which can ensure a certain fixing effect on the lens 9 and the focusing lens 12 without damaging them. Moreover, the multiple moving strips 11 are slidably connected to the mounting cylinder 3 and the focusing lens 12 respectively, and the multiple moving strips 11 are bonded to the multiple lenses 9 respectively. This connection method not only facilitates the installation and removal of the lens 9 and the focusing lens 12, but also ensures their stable position inside the mounting cylinder 3.

[0047] The moving assembly 13 includes an electric telescopic rod 131, an internally threaded tube 132, a screw 133, a gear 134, a gear ring 135, and a rotating ring 136;

[0048] An electric telescopic rod 131 is slidably connected inside the mounting cylinder 3. The output end of the electric telescopic rod 131 is slidably connected to the focusing lens 12. An internally threaded tube 132 is fixedly connected to the side wall of the electric telescopic rod 131. The internally threaded tube 132 is slidably connected to the mounting cylinder 3. A screw 133 is threaded inside the internally threaded tube 132. A gear 134 is fixedly connected to one end of the screw 133. A gear ring 135 meshes with the outside of the gear 134. A rotating ring 136 is fixedly connected to the outside of the gear ring 135. The mounting cylinder 3 is rotatably connected to the screw 133, the gear 134, the gear ring 135, and the rotating ring 136 respectively. Two symmetrically distributed third sealing rings 137 are fixedly connected to the outside of the mounting cylinder 3. The two third sealing rings 137 are rotatably connected to the rotating ring 136 respectively.

[0049] In this embodiment, the design of the moving component 13 allows the optical lens to flexibly adjust the position of the focusing lens 12 according to different shooting distances and imaging requirements, thereby achieving a clear imaging effect. The electric telescopic rod 131 is a device that can achieve telescopic movement through electric power. Its output end is slidably connected to the focusing lens 12, which can directly drive the focusing lens 12 to move. The internally threaded tube 132 can slide in a specific direction within the mounting cylinder 3. When the rotating ring 136 is rotated, the rotating ring 136 drives the gear ring 135 to rotate, and the gear ring 135 drives the gear meshing with it. When gear 134 rotates, it drives screw 133 to rotate. Since screw 133 is threadedly connected to internal threaded tube 132, the rotation of screw 133 causes internal threaded tube 132 to slide inside mounting cylinder 3. Internal threaded tube 132 drives electric telescopic rod 131 to move, and then electric telescopic rod 131 drives focusing lens 12 to move inside mounting cylinder 3, thereby adjusting the position of focusing lens 12. Two third sealing rings 137 are rotatably connected to rotating ring 136 respectively. The third sealing rings 137 can effectively prevent external impurities from entering the interior of mounting cylinder 3, ensuring the normal operation of moving component 13.

[0050] Limiting rings 8 are fixedly connected to both sides of the fixed plate 7, and the two limiting rings 8 are in contact with the lens 9 and the moving strip 11 respectively.

[0051] In addition, the two limiting rings 8 play an important positioning and limiting role inside the mounting cylinder 3. The two limiting rings 8 contact the lens 9 and the moving strip 11 respectively, which can precisely control the position of the lens 9 and the moving strip 11 inside the mounting cylinder 3, preventing them from moving or shifting unnecessarily during use, thereby ensuring the imaging quality and stability of the optical lens. The design of the limiting rings 8 has been carefully considered. Their size and position are matched with the lens 9 and the moving strip 11, and can provide reliable limiting function without affecting their normal installation and sliding.

[0052] The mounting cylinder 3 is provided with a sealing assembly, which includes a first sealing ring 102, a first sealing groove 301, a second sealing groove 302, and a second sealing ring 402.

[0053] The mounting cylinder 3 has a first sealing groove 301 and a second sealing groove 302 respectively on both sides. A first sealing ring 102 is fixedly connected inside the mounting base 1. The first sealing ring 102 is in contact with the first sealing groove 301. A second sealing ring 402 is fixedly connected inside the sealing cover 4. The second sealing ring 402 is in contact with the second sealing groove 302. A limiting cylinder 103 is fixedly connected inside the mounting base 1. The limiting cylinder 103 is slidably connected to the mounting cylinder 3. The limiting cylinder 103 is in contact with the lens 9 and the moving strip 11.

[0054] Preferably, a first sealing ring 102 is fixedly connected inside the mounting base 1. The first sealing ring 102 is made of a highly elastic sealing material and has good sealing performance. When the mounting cylinder 3 is installed inside the mounting base 1, the first sealing ring 102 is in close contact with the first sealing groove 301, forming a reliable sealing barrier. A second sealing ring 402 is fixedly connected inside the sealing cover 4. Similarly, when the sealing cover 4 is installed at the end of the mounting cylinder 3, the second sealing ring 402 is in close contact with the second sealing groove 302, further enhancing the sealing effect. In addition, a limiting cylinder 103 is fixedly connected inside the mounting base 1. The limiting cylinder 103 is slidably connected to the mounting cylinder 3. The limiting cylinder 103 can not only position and limit the position of the mounting cylinder 3, but also contact the lens 9 and the moving strip 11, preventing impurities from entering the interior of the mounting cylinder 3 from the side to a certain extent, providing all-round sealing protection for the optical lens.

[0055] The installation sequence of the optical lens is as follows:

[0056] Step 1: Attach two lenses 9 to the inside of multiple moving strips 11 respectively, and place them into the inside of the mounting cylinder 3 near the mounting base 1 in sequence. At the same time, slide the mounting arc 10 into the inside of the mounting cylinder 3 so that the mounting arc 10 contacts the mounting base 1 respectively. Install the mounting cylinder 3 into the inside of the mounting base 1 by means of threaded connection to ensure that the mounting cylinder 3 and the mounting base 1 are initially fixed. The limiting cylinder 103 limits the moving strips 11 and lenses 9.

[0057] Step 2: Install the other two lenses 9 inside the other moving strips 11, and place them into the end of the mounting cylinder 3 away from the mounting base 1 in sequence. Spread the moving strips 11 open. First, install the focusing lens 12 inside the multiple moving strips 11 and make the focusing lens 12 stick to the lens 9. Then slide the mounting arc 10 into the mounting cylinder 3, rotate the sealing cover 4, and install the sealing cover 4 at the end of the mounting cylinder 3 away from the mounting base 1.

[0058] Step 3: Fix the two fixing rings 61 to appropriate positions on the outside of the mounting cylinder 3. When installing the mounting cylinder 3 and the sealing cover 4, the mounting base 1 and the sealing cover 4 compress the limiting rods 64. When the mounting cylinder 3 and the sealing cover 4 are installed in place, under the elastic force of the elastic rod 62, multiple limiting rods 64 are inserted into the first limiting hole 101 and the second limiting hole 401 respectively, thereby limiting the mounting cylinder 3 and the mounting base 1 and the mounting cylinder 3 and the sealing cover 4 respectively.

[0059] Step 4: After installation, the first sealing ring 102 inside the mounting base 1 contacts the first sealing groove 301 on one side of the mounting cylinder 3, and the second sealing ring 402 inside the sealing cover 4 contacts the second sealing groove 302 on the other side of the mounting cylinder 3, thus achieving a sealing effect.

[0060] Step 5: After all lenses are installed, insert the output end of the electric telescopic rod 131 into the inside of the focusing lens 12, rotate the rotating ring 136, the rotating ring 136 drives the gear ring 135 to rotate, the gear ring 135 drives the gear 134 meshing with it to rotate, the gear 134 drives the screw 133 to rotate. Since the screw 133 is threadedly connected to the internal threaded tube 132, the rotation of the screw 133 will cause the internal threaded tube 132 to slide in the mounting cylinder 3. The internal threaded tube 132 drives the electric telescopic rod 131 to move, and the electric telescopic rod 131 drives the focusing lens 12 to move in the mounting cylinder 3, thereby realizing the adjustment of the position of the focusing lens 12.

[0061] Step 6: Push the moving ring 63 corresponding to the sealing cover 4 to compress the elastic rod 62, and pull the limiting rod 64 out from the second limiting hole 401 to release the limiting of the sealing cover 4. Rotate the sealing cover 4 to unscrew it from the end of the mounting cylinder 3. Pull the mounting arc 10. Since the moving strip 11 is bonded to the lens 9, the movement of the mounting arc 10 will drive the moving strip 11 and the lens 9 to move together, thereby removing multiple lenses 9 and focusing lens 12 from the mounting cylinder 3.

[0062] Step 7: Push the movable ring 63 corresponding to the mounting base 1 to compress the elastic rod 62, and pull the limiting rod 64 out from the first limiting hole 101 to release the limitation on the mounting cylinder 3. Rotate the mounting cylinder 3 to unscrew it from the internal thread of the mounting base 1 to complete the disassembly of the entire optical lens.
