Description

Technical Field

[0001] This utility model relates to the field of optical glass lenses, and specifically to an optical glass lens. Background Technology

[0002] Optical glass lenses are optical elements made of high-purity optical glass material. Through precision processing, they are formed with a specific curvature and use the principle of light refraction to converge, diverge, or shape light rays, thereby achieving optical path control and imaging functions. Optical glass lenses are the most basic optical elements in optical instruments such as microscopes and telescopes. In scientific research and experimental fields, optical glass lenses play an important role in promoting technological progress.

[0003] A search revealed an optical glass lens assembly with publication number CN220232083U. This assembly, belonging to the field of lens assembly structure technology, includes a lens mounting cylinder, a lens element, a protective wiping element, a protective trigger rod, a lens mounting mechanism, and a lens protection mechanism. The lens element is disposed inside the lens mounting cylinder. Two sets of protective wiping elements are rotatably connected inside the lens mounting cylinder. The protective trigger rod is slidably connected above the rear end of the lens mounting cylinder. The lens mounting mechanism and the lens protection mechanism are both located inside the lens mounting cylinder. This arrangement enables wiping of the lens surface, ensuring the lens's performance, protecting the lens, preventing external dust from adhering to the lens surface, and extending the lens's lifespan.

[0004] In the use of existing optical glass lenses, due to the different usage environments, if the optical glass lenses lack quick disassembly and assembly, buffer design, and modular stacking capabilities, it will lead to the need to disassemble the entire equipment to replace a single lens, increasing downtime. Moreover, the rigid contact between the lens and the housing makes it easy for stress cracking and image quality degradation to occur due to long-term vibration or impact. Furthermore, the optical glass lenses in the aforementioned comparative cases also lack quick disassembly and assembly, buffer design, and modular stacking capabilities. This increases the failure rate and maintenance costs of the optical glass lenses in the long run.

[0005] Therefore, it is necessary to invent an optical glass lens to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an optical glass lens that, through an optical glass lens sheet, an outer lens edge, an upper buffer washer, a lower buffer washer, a first assembly shell, a second assembly shell, an upper stacking groove, and a lower stacking block, enables the optical glass lens to have the advantages of quick assembly / disassembly, buffer design, and modular stacking. This reduces the failure rate and maintenance cost of the optical glass lens, and also allows the optical glass lens to adapt to technological iterations and changes in scenarios. It also supports the integrated use of complex optical systems in a compact space. This addresses the problem in existing optical glass lenses where, due to different usage environments, the lack of quick assembly / disassembly, buffer design, and modular stacking capabilities leads to the need to disassemble the entire device to replace a single lens sheet, increasing downtime. Furthermore, the rigid contact between the lens and the housing makes it susceptible to stress cracking and image quality degradation due to long-term vibration or impact. The optical glass lenses in the aforementioned comparative cases also lacked quick assembly / disassembly, buffer design, and modular stacking capabilities, which increased the failure rate and maintenance cost of the optical glass lens over long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an optical glass lens, comprising an optical glass lens sheet and a body for focusing light for observation;

[0008] An anti-glare coating is applied to the outside of an optical glass lens to increase its anti-glare capability. An outer lens edge is fixedly installed on the outside of the optical glass lens. An upper buffer gasket is fixedly attached above the outer lens edge, and a lower buffer gasket is fixedly attached below the outer lens edge.

[0009] The first assembly shell is sleeved on the outside of the optical glass lens for easy assembly. Both ends of the first assembly shell have mating slots on their inner sides. A mating block is movably engaged inside the mating slot. The second assembly shell is fixedly installed on the outside of the mating block. Upper and lower limit blocks are fixedly installed inside both the first and second assembly shells.

[0010] The upper stacking groove has the upper surface of the first and second assembly shells for lens combination and stacking. The bottom of the first and second assembly shells is fixedly installed with a lower stacking block. The lower part of the first and second assembly shells is engaged with an assembly ring, and an inner optical glass lens is sleeved inside the assembly ring.

[0011] Preferably, the anti-glare coating is tightly bonded to the optical glass lens, and the material of the anti-glare coating is nano-silica.

[0012] Preferably, the docking block fixedly installed on the outside of the second assembly shell engages with the docking slot opened inside the first assembly shell, and the docking block and the docking slot are used in conjunction.

[0013] Preferably, the number of upper and lower limiting blocks is set to multiple, and the multiple upper and lower limiting blocks are distributed at equal intervals inside the first assembly shell and the second assembly shell.

[0014] Preferably, an external magnetic absorbing plate is fixedly installed on the outside of the first assembly shell and the second assembly shell, and a first mirror ring and a second mirror ring are sleeved on the outside of the first assembly shell and the second assembly shell.

[0015] Preferably, mounting plates are fixedly connected to both ends of the first mirror ring and the second mirror ring, and double-ended bolts are threaded through the external threads of the mounting plates. The first mirror ring and the second mirror ring are threadedly connected, and an inner magnetic absorbing plate is fixedly installed inside the second mirror ring.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model includes an optical glass lens, an outer lens edge, an upper buffer washer, a lower buffer washer, a first assembly shell, a second assembly shell, an upper stacking groove, and a lower stacking block. When using this optical glass lens, the upper and lower buffer washers can be attached to the upper and lower sides of the optical glass lens via the outer lens edge. Then, the first and second assembly shells are fitted onto the outside of the optical glass lens using the mating groove and mating block. This differs from traditional threaded or adhesive fixing methods, allowing for quick assembly and disassembly of the optical glass lens. Simultaneously, the upper and lower buffer washers are positioned within the optical glass lens... The edges are used to absorb vibration and impact, avoiding stress concentration in the optical glass lens due to rigid contact. Moreover, when multiple optical glass lenses are stacked, the upper stacking groove and lower stacking block of the first and second assembly shells can be coupled and embedded with the assembly ring to achieve vertical stacking. This allows the optical glass lens to have the advantages of quick assembly and disassembly, buffer design and modular stacking over long-term use, which can reduce the failure rate and maintenance cost of the optical glass lens. It also allows the optical glass lens to adapt to technological iteration and scene changes, and supports the integrated use of complex optical systems in a compact space.

[0018] 2. This utility model is equipped with an outer magnetic absorbing plate, a first lens ring, a mounting plate, a double-headed bolt, a second lens ring, and an inner magnetic absorbing plate. When multiple optical glass lenses are stacked on top of each other through the first and second assembly shells and the assembly ring, the first and second lens rings can be quickly attached to the outside of the stacked optical glass lenses by the mutual attraction between the outer and inner magnetic absorbing plates. This speeds up the work efficiency of the assembly line and reduces the skill requirements of the operators. Moreover, this method of stacking first and then magnetically attaching supports the rapid switching of optical glass lenses with different focal lengths, allowing the optical glass lenses to adapt to the inspection of workpieces of different sizes. It can also realize multimodal imaging in medical equipment through the stacking of optical glass lenses. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6 An optical glass lens is shown, comprising an optical glass lens sheet 1 and a body for focusing light for observation;

[0030] An anti-glare coating 2 is applied to the outside of the optical glass lens 1 to increase the anti-glare capability. An outer lens edge 3 is fixedly installed on the outside of the optical glass lens 1. An upper buffer gasket 4 is fixedly attached above the outer lens edge 3, and a lower buffer gasket 5 is fixedly attached below the outer lens edge 3.

[0031] The first assembly shell 6 is sleeved on the outside of the optical glass lens 1 for easy assembly. Both ends of the first assembly shell 6 have mating slots 7 on their inner sides. The mating slots 7 are movably engaged with mating blocks 8. The outside of the mating blocks 8 is fixedly installed with a second assembly shell 9. Both the first assembly shell 6 and the second assembly shell 9 have upper and lower limit blocks 10 fixedly installed inside.

[0032] The upper stacking groove 11 has an upper surface for the first assembly shell 6 and the second assembly shell 9 for lens combination and stacking. The bottom of the first assembly shell 6 and the second assembly shell 9 are fixedly installed with a lower stacking block 12. The lower part of the first assembly shell 6 and the second assembly shell 9 is engaged with an assembly ring 13. An inner optical glass lens 14 is sleeved inside the assembly ring 13. The optical glass lens 1 can be attached to the upper and lower sides of the outer lens along the edge 3 with buffer washers 4 and lower buffer washers 5. Then, the first assembly shell 6 and the second assembly shell 9 are sleeved on the outside of the optical glass lens 1 through the docking slot 7 and the docking block 8. This is different from the traditional threaded or adhesive fixing method, which supports the quick assembly and disassembly of the optical glass lens. At the same time, the upper buffer washers 4 and lower buffer washers 5 are located at the edge of the optical glass lens 1 to absorb vibration and impact, avoiding the problem of stress concentration of the optical glass lens 1 caused by rigid contact.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the anti-glare coating 2 is tightly bonded to the optical glass lens 1. The material of the anti-glare coating 2 is nano-silica. The anti-glare coating 2 increases the anti-glare capability of the optical glass lens 1. In this way, the intensity of reflected light is reduced through the Mie scattering effect, thereby improving the performance of the optical glass lens. The docking block 8, which is fixedly installed on the outside of the second assembly shell 9, engages with the docking slot 7 opened inside the first assembly shell 6. The docking block 8 and the docking slot 7 work together to fit the first assembly shell 6 and the second assembly shell 9 onto the outside of the optical glass lens 1 through the docking slot 7 and the docking block 8. This is different from the traditional threaded or adhesive fixing method and supports the quick assembly and disassembly of the optical glass lens.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, multiple upper and lower limiting blocks 10 are provided, and these blocks are evenly spaced inside the first assembly shell 6 and the second assembly shell 9. These blocks clamp the optical glass lens 1 within the first and second assembly shells 6 and 9, thus stabilizing its normal use. External magnetic absorbing plates 15 are fixedly installed on the outside of the first and second assembly shells 6 and 9. A first lens ring 16 and a second lens ring 19 are sleeved on the outside of the first and second assembly shells 6 and 9. When multiple optical glass lenses 1 are stacked on top of each other using the first and second assembly shells 6 and the second assembly shells 9 and the mounting ring 13, they can be used... The mutual attraction between the outer magnetic accumulator 15 and the inner magnetic accumulator 20 allows for the rapid attachment of the first lens ring 16 and the second lens ring 19 to the outside of the stacked optical glass lenses. Mounting plates 17 are fixedly connected to both ends of the first lens ring 16 and the second lens ring 19. Double-ended bolts 18 pass through the external threads of the mounting plates 17, and the first lens ring 16 and the second lens ring 19 are threaded together. The inner magnetic accumulator 20 is fixedly installed inside the second lens ring 19. This method of stacking first and then magnetically attaching allows for the rapid switching of optical glass lenses with different focal lengths, enabling the optical glass lenses to adapt to the inspection of workpieces of different sizes. It also enables multimodal imaging in medical equipment through the stacking of optical glass lenses.

[0035] The working principle of this practical application is as follows: First, take out the optical glass lens. According to the current usage requirements of the optical glass lens, first attach the buffer gaskets 4 and 5 to the upper and lower sides of the optical glass lens sheet 1 along the edge 3 of the outer lens. Then, the first assembly shell 6 and the second assembly shell 9 are sleeved on the outside of the optical glass lens sheet 1 through the docking slot 7 and the docking block 8. This method, unlike traditional threaded or adhesive fixing methods, supports quick assembly and disassembly of the optical glass lens. At the same time, the upper buffer gaskets 4 and 5 are located at the edge of the optical glass lens sheet 1 to absorb vibration and impact, avoiding the stress concentration problem of the optical glass lens sheet 1 caused by rigid contact. Then, when multiple optical glass lenses are stacked, the upper stacking groove 11 and the lower stacking block 12 of the first assembly shell 6 and the second assembly shell 9 can be coupled and embedded with the assembly ring 13 to achieve vertical stacking. After multiple optical glass lens pieces 1 are stacked on top of each other with the assembly ring 13 via the first assembly shell 6 and the second assembly shell 9, the first lens ring 16 and the second lens ring 19 can be quickly attached to the outside of the stacked optical glass lenses by the mutual attraction between the outer magnetic accumulator 15 and the inner magnetic accumulator 20. This speeds up the work efficiency of the assembly line, reduces the skill requirements of the operators, and provides the optical glass lens with the advantages of quick disassembly and assembly, buffer design and modular stacking in long-term use. This can reduce the failure rate and maintenance cost of the optical glass lens, and also make the optical glass lens adaptable to technological iteration and scene changes. It also supports the integrated use of complex optical systems in a compact space. Finally, after completing the installation and use of all the optical glass lenses according to the above operations, the device can be maintained in daily life. In this way, the use process of the optical glass lens is completed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
