Description

Technical Field

[0001] This utility model relates to the field of optical instrument accessories, and in particular to an aperture lens cap and a lens. Background Technology

[0002] Currently, imaging equipment is continuously developing towards multifunctionality and high integration, and users are increasingly demanding protection for lenses (objectives), discreet use, and miniaturization of products. Especially in space-constrained product designs, there is a need for an objective cover that can reliably shield and open the lens within a limited space, and still provide a certain degree of protection after opening.

[0003] In existing technologies, the objective lens cover of imaging devices mostly adopts a flip-top structure. This type of structure has obvious limitations: First, opening and closing the flip-top requires a large operating space, which is difficult to achieve in compact products or affects the overall layout; Second, when the flip-top is open, the lens is completely exposed, and the lens is easily scratched, bumped, or contaminated, posing a high risk of lens damage in outdoor activities, live-action CS games, and other usage scenarios.

[0004] Therefore, there is an urgent need for a lens cap that can adapt to limited installation space, enable quick opening and closing, and provide continuous protection and concealment for the lens when open. Utility Model Content

[0005] The purpose of this invention is to provide an aperture lens cap that allows for complete lens coverage and opening within a limited space through rotational adjustment. In the open state, the honeycomb mesh effectively protects the lens and enhances concealment, and it is easy to install and remove. Another purpose of this invention is to provide a lens including the aforementioned aperture lens cap.

[0006] To achieve the above objectives, this utility model provides an aperture lens cover, including an aperture assembly and a honeycomb mesh assembly connected to each other. The aperture assembly is disposed at the front end of the lens, and the honeycomb mesh assembly is connected to the end of the aperture assembly away from the lens. The aperture assembly includes an adjustment handwheel and blades. The light-transmitting aperture of the blades is adjusted by adjusting the handwheel, thereby controlling the lens to open or close.

[0007] Furthermore, the aperture assembly includes an aperture seat, an aperture seat and an adjusting handwheel, one of which is provided with a limiting element, and the other is provided with a limiting groove adapted to the limiting element. When the adjusting handwheel adjusts the light transmission aperture of the blade, the limiting element and the limiting groove engage.

[0008] Furthermore, at least two limit slots are provided.

[0009] Furthermore, the limiting groove includes a first limiting groove and a second limiting groove. When the blade is fully closed, the limiting member engages with the first limiting groove; when the blade is fully open, the limiting member engages with the second limiting groove.

[0010] Furthermore, the aperture assembly includes a rotating component installed in the aperture seat, the rotating component being connected to the blade, and the rotating component being linked to an adjusting handwheel, thereby controlling the movement of the blade by rotating the adjusting handwheel.

[0011] Furthermore, the rotating component is provided with multiple slots, and the blades are installed in the slots and move along the extension direction of the slots.

[0012] Furthermore, the rotating part is provided with a protrusion, and the aperture seat is provided with a rotating channel. The protrusion passes through the rotating channel and is connected to the adjusting handwheel. Rotating the adjusting handwheel drives the protrusion to move along the rotating channel.

[0013] Furthermore, the cellular network assembly includes interconnected cellular network bases and cellular networks, with a pressure ring provided on one side of the cellular network.

[0014] Furthermore, a resilient retaining ring is provided on the side of the rotating component away from the cellular mesh assembly.

[0015] This utility model provides a lens, including an aperture lens cap as described in any of the above.

[0016] The beneficial effects of this utility model are as follows: 1. Good spatial adaptability and simple operation: The lens can be opened and closed by rotating the adjustment handwheel to change the aperture diameter, without the need for the large operating space required by flip-top, making it extremely suitable for various optoelectronic products with compact structure and limited space.

[0017] 2. Protection and concealment functions when open: The honeycomb mesh component located at the front of the aperture can effectively prevent foreign objects such as tree branches, bullet casings, and dust from directly hitting or scratching the lens surface when the aperture is open. At the same time, the honeycomb structure can scatter stray light and reduce reflections from the internal lens barrel, improving the concealment of the equipment during use.

[0018] 3. Reliable positioning: The aperture assembly is equipped with a limiting structure to ensure that the blades can be stably locked in the fully open and fully closed positions, preventing accidental contact from changing the light aperture and affecting observation.

[0019] 4. Modular design, highly versatile: The aperture assembly and the honeycomb mesh assembly are connected by threads, allowing for optional installation of the honeycomb mesh assembly. The entire lens cap is also connected to the lens by threads, making disassembly, replacement, and maintenance convenient.

[0020] This utility model also provides a lens including the above-mentioned aperture lens cap. Since the above-mentioned aperture lens cap has the above-mentioned technical effects, the above-mentioned lens should also have the same technical effects, which will not be described in detail here.

Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The core of this invention is to provide an aperture lens cap. By setting a honeycomb mesh assembly 2 and an aperture assembly 1, and changing the aperture diameter by rotating the adjustment handwheel 11, the lens 3 can be opened and closed. This eliminates the need for the large operating space required for flip-top covers, making it extremely suitable for various optoelectronic products with compact structures and limited space. Another core aspect of this invention is to provide a lens 3 that includes the aforementioned aperture lens cap.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 9 The present invention provides an aperture lens cover, including an aperture assembly 1 and a honeycomb mesh assembly 2 connected to each other. The aperture assembly 1 is disposed at the front end of the lens 3, and the honeycomb mesh assembly 2 is connected to the end of the aperture assembly 1 away from the lens 3. The aperture assembly 1 includes an adjustment handwheel 11 and a blade 12. The light-transmitting aperture of the blade 12 is adjusted by adjusting the handwheel 11, thereby controlling the lens 3 to open or close.

[0027] This utility model provides an aperture lens cover, which combines an aperture assembly 1 and a honeycomb mesh assembly 2 to form a lens cover. Rotating the adjustment handwheel 11 controls the light-transmitting aperture of the blades 12 to open or close the aperture assembly 1. The user can rotate the adjustment handwheel 11 to drive all the blades 12 to move synchronously, thereby continuously changing the central light-transmitting aperture formed by the blades 12. When the aperture is adjusted to the minimum (blades 12 are closed), the lens 3 is completely blocked; when the aperture is adjusted to the maximum (blades 12 are open), the lens 3 is completely unobstructed. The rotation operation replaces the traditional flip-top action, completely eliminating the need for lateral operation space, making this lens cover perfectly adaptable to various optoelectronic devices with highly compact spaces. The honeycomb mesh assembly 2 keeps the lens 3 in a protected state, preventing it from being scratched by foreign objects, and can scatter stray light and reduce internal lens barrel reflections, improving the concealment of the device during use. In addition, both the aperture assembly 1 and the honeycomb assembly 2 are detachable. For example, the honeycomb assembly 2 can be detachably connected to the aperture assembly 1 or the lens 3, and the aperture assembly 1 can be detachably connected to the lens 3. This can be done through threaded connection or snap-fit ​​connection, allowing users to freely choose to install the honeycomb assembly 2 or the aperture assembly 1, making the combination flexible and the use diverse.

[0028] Furthermore, such as Figures 1 to 9 As shown, the aperture assembly 1 includes an aperture seat 13. One of the aperture seat 13 and the adjusting handwheel 11 is provided with a limiting member 14, and the other is provided with a limiting groove 15 adapted to the limiting member 14. When the adjusting handwheel 11 adjusts the light transmission aperture of the blade 12, the limiting member 14 and the limiting groove 15 are engaged.

[0029] In this embodiment, the aperture assembly 1 is provided with a limiting structure. This can be achieved by providing a limiting member 14 on the aperture seat 13 and a limiting groove 15 on the adjusting handwheel 11, or by providing a limiting groove 15 on the aperture seat 13 and a limiting member 14 on the adjusting handwheel 11. Taking the limiting member 14 on the aperture seat 13 as an example, the limiting member 14 can be a spherical ball, and the limiting groove 15 is an arc-shaped groove. Specifically, the limiting member 14 is fixedly connected to the aperture seat 13. When the adjusting handwheel 11 is rotated to adjust the aperture diameter, the limiting groove 15 can engage with the limiting member 14 at a preset position. Multiple limiting grooves 15 can be provided, ensuring engagement and stabilization at the current adjustment position when the aperture diameter is at different sizes. This prevents the blade 12 from moving due to vibration, impact, or accidental contact, thus affecting observation, improving observation stability and reliability, and providing a clear tactile feedback to indicate the current status of the lens cap to the user. Alternatively, the limiting member 14 and the aperture seat 13 can also be elastically connected. For example, an elastic member can be provided between the limiting member 14 and the aperture seat 12, and the limiting member 14 can engage with different limiting grooves 15 under the action of the elastic member.

[0030] Furthermore, such as Figures 1 to 9 As shown, at least two limiting grooves 15 are provided. The limiting grooves 15 include a first limiting groove 151 and a second limiting groove 152. When the blade 12 is fully closed, the limiting member 14 is engaged with the first limiting groove 151; when the blade 12 is fully open, the limiting member 14 is engaged with the second limiting groove 152.

[0031] In this embodiment, the limiting groove 15 is preferably provided as two, respectively provided when the blade 12 is fully closed and when the blade 12 is fully open. That is, when the blade 12 is fully closed, the limiting member 14 engages with the first limiting groove 151, so that the blade 12 can be fixed in the closed state and is not affected by external environmental vibration. When the blade 12 is fully open, the limiting member 14 engages with the second limiting groove 152, so that the blade 12 can be fixed in the open state and maintain a stable observation state.

[0032] Furthermore, such as Figures 1 to 9 As shown, the aperture assembly 1 includes a rotating member 16 installed in the aperture seat 13. The rotating member 16 is connected to the blade 12 and is linked to the adjusting handwheel 11. The blade 12 is controlled to move by rotating the adjusting handwheel 11.

[0033] The rotating component 16 is provided with multiple slots 161, and the blade 12 is installed in the slots 161 and moves along the extension direction of the slots 161.

[0034] The rotating part 16 is provided with a protrusion 162, and the aperture seat 13 is provided with a rotating channel 131. The protrusion 162 passes through the rotating channel 131 and is connected to the adjusting handwheel 11. Rotating the adjusting handwheel 11 drives the protrusion 162 to move along the rotating channel 131.

[0035] In this embodiment, a rotatable rotating component 16 is provided inside the aperture seat 13. On the end face of the rotating component 16, a plurality of radially extending, elongated slots 161 (e.g., ...) are uniformly formed along the circumference. Figure 5 (As shown). Each blade 12 has a mounting post 121 at its tail end, which is slidably nested in the corresponding slot 161. Simultaneously, a radially outwardly extending protrusion 162 (like a cylindrical pin) is provided on the outer edge of the rotating component 16. An arc-shaped rotating channel 131 is correspondingly formed on the side wall of the aperture seat 13. The protrusion 162 passes through this rotating channel 131 and is fixedly connected to the adjusting handwheel 11. When the user rotates the adjusting handwheel 11, the handwheel 11 drives the rotating component 16 to rotate synchronously via the protrusion 162. The rotation of the rotating component 16 pushes the mounting post 121 of the blade 12 through the groove wall of its slot 161, forcing all blades 12 to slide synchronously along the guide trajectory of the slot 161, thereby achieving a smooth, concentric change in the light transmission aperture. The effect of this transmission scheme is that it has a compact structure, reliable linkage, and ensures precise synchronization of the multi-blade movement.

[0036] Multiple blades 12 are provided, and each blade 12 has a mounting post 121 at both ends. The two mounting posts 121 are arranged in opposite directions. One of them is connected to the slot 161, and the other mounting post 121 is connected to the mounting hole 132 of the aperture seat 13. When the blade 12 rotates, the mounting post 121 connected to the mounting hole 132 rotates along the axis, that is, the mounting post 121 will rotate on its own axis. The mounting post 121 connected to the slot 161 is driven to rotate by the slot 161, that is, the mounting post 121 rotates with the adjustment handwheel 11. The mounting post 121 can slide along the groove wall of the slot 161. The design of the two mounting posts 121 allows the blade 12 to move closer to or further away from the light-transmitting hole, so as to open or close the light-transmitting hole.

[0037] Furthermore, such as Figures 1 to 9 As shown, the cellular network assembly 2 includes a cellular network base 21 and a cellular network 22 that are connected to each other, and a pressure ring 23 is also provided on one side of the cellular network 22.

[0038] The honeycomb mesh 22 is composed of metal sheets with dense hexagonal through holes, placed inside the honeycomb mesh base 21, and pressed and fixed from the front by the pressure ring 23 (e.g., Figure 8 (As shown). The effects of this component include: physically, it can effectively block flying sand, pebbles, branches, and game projectiles (such as PP bullets) from directly impacting the lens; optically, its honeycomb structure can significantly scatter side stray light and suppress internal reflections in the lens barrel, thereby improving the device's stealth in complex lighting environments such as the field and improving image contrast.

[0039] Furthermore, such as Figures 1 to 9As shown, an elastic retaining ring 163 is provided on the side of the rotating component 16 away from the cellular mesh assembly 2.

[0040] In this embodiment, to ensure the axial stability of the rotating component 16 and prevent it from shifting during use, an elastic retaining ring 163 is provided on one side of the rotating component 16 to fix the rotating component 16 within the aperture seat 13. The elastic retaining ring 163 engages with the corresponding groove in the aperture seat 13, providing a continuous axial constraint force for the rotating component 16. This enhances the rigidity and durability of the entire transmission mechanism, ensuring long-term reliability, while also ensuring that the rotational movement of the rotating component 16 is not affected. The elastic retaining ring 163 can be configured as an open-ended ring.

[0041] The working principle of the aperture lens cap provided in this application is as follows: When the blade 12 is in the closed state, the limiting member 14 engages with the first limiting groove 151, and the aperture assembly 1 is closed, that is, the lens 3 is in a blocked state. When it is necessary to open the aperture assembly 1, the rotating adjustment handwheel 11 is rotated, and the adjusting handwheel 11 drives the rotating member 16 to rotate, which in turn drives the blade 12 located inside the rotating member 16 to rotate, until the limiting member 14 engages with the second limiting groove 152, opening the aperture assembly 1, that is, the lens 3 is in an unblocked state. The opening size of the aperture assembly 1 can be manually controlled, and the amount of light entering the lens 3 can be adjusted according to the observation needs.

[0042] In addition to the aforementioned aperture lens cap, this utility model also provides a lens 3 including the aforementioned aperture lens cap. For the structure of other parts of the lens 3, please refer to the prior art, which will not be repeated here.

[0043] The aperture lens cap and lens 3 provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
