Description

A honeycomb hood assembly for a sight Technical Field

[0001] This invention belongs to the field of sight technology, and specifically relates to a honeycomb cover assembly for sights. Background Technology

[0002] The protection of existing sight eyepieces or objectives mainly relies on protective covers connected to the sight body, which are generally made of plastic or metal and have good protective performance. However, in order to reduce the interference of stray light around the objective lens or reduce reflections that could lead to detection by the other party, a honeycomb cover assembly has been designed to reduce the interference of stray light around the objective lens and avoid exposure caused by reflections.

[0003] Figure 1 shows a conventional honeycomb cover assembly design, in which the honeycomb mesh 1 is fixed inside the honeycomb mesh fixing ring, i.e., the honeycomb mesh outer shell 2. The honeycomb mesh outer shell 2 (i.e., the honeycomb mesh fixing ring) is fixed inside the connecting ring 3. The connecting ring 3 is threadedly connected to the lens front pressure ring 4 of the sight objective lens (objective lens assembly) mounting shell (specifically, the outer rear end of the connecting ring 3 is threadedly connected to the inner side of the lens front pressure ring 4). A lens protector is fitted to the front end of the connecting ring 3 (a protective glass 6 is installed inside the protective cover 5 of the lens protector, and the collar 8 of the lens protector is fitted outside the front end of the connecting ring 3, protecting...). The cover 5 is hinged to one side of the collar 8 and can be flipped to cover or remove the objective lens. This structure has at least two obvious drawbacks. First, the honeycomb cover assembly (honeycomb mesh 1, honeycomb mesh shell 2 and honeycomb mesh pressure ring 7 of honeycomb mesh 1 shown in Figure 2) is assembled with the lens front pressure ring 4 and lens protection component through the connecting ring 3. It is long, has many components, and is cumbersome to assemble. Second, the honeycomb mesh shell 2 is limited by the threaded connection between the front end of the connecting ring 3 and the honeycomb mesh shell 2. Disassembly and assembly require special tools, which is troublesome and not conducive to field operations. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as large length, cumbersome assembly, and inconvenience for field operations.

[0005] To achieve the above objectives, the present invention provides a honeycomb cover assembly for a sight, including a honeycomb mesh, a honeycomb mesh fixing ring, and a honeycomb mesh cover pressure ring, wherein a first inner ring retaining edge is provided on the outer side of the inner ring of the honeycomb mesh fixing ring along the axial direction.

[0006] The honeycomb mesh pressing ring is fastened to the inner ring of the honeycomb mesh fixing ring through a snap-fit ​​structure set on its axial outer periphery. The honeycomb mesh is pressed against the first inner ring stop by the second inner ring stop set on the axial inner side of the inner ring of the honeycomb mesh fixing ring, thereby fixing the honeycomb mesh inside the honeycomb mesh fixing ring. A threaded connecting ring is provided on the axial inner side of the honeycomb mesh fixing ring, and an external thread is provided on its outer circumferential surface. The outer diameter of the threaded connecting ring is smaller than the outer diameter of the honeycomb mesh fixing ring, and its inner wall is flush with the outer edge of the first inner ring stop.

[0007] Furthermore, the surface of the honeycomb mesh retaining ring is textured with a grid pattern to improve friction and stability during operation.

[0008] Furthermore, the snap-fit ​​structure includes a plurality of male snaps evenly arranged circumferentially on the side of the honeycomb mesh fixing ring facing the first inner ring edge, and corresponding matching annular grooves or female snaps arranged on the inner ring wall of the honeycomb mesh fixing ring.

[0009] Furthermore, the male buckle includes a plurality of circumferentially evenly distributed spring pieces fixedly connected to the honeycomb mesh fixing ring, and an arc-shaped protrusion formed on the outer wall of the free end of the spring piece.

[0010] The advantages of this invention are: compact structure, few components, and can be operated by hand. Attached Figure Description

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "aligned", "overlapping", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] This embodiment provides a honeycomb cover assembly for a sight as shown in Figure 3, including a honeycomb mesh 1, a honeycomb mesh fixing ring 2, and a honeycomb mesh pressing ring 7. The honeycomb mesh fixing ring 2 has a first inner ring retaining edge 9 on its axially outer side. The honeycomb mesh pressing ring 7 is fastened to the inner ring of the honeycomb mesh fixing ring 2 via a snap-fit ​​structure on its axially outer periphery. The honeycomb mesh 1 is pressed against the first inner ring retaining edge 9 by a second inner ring retaining edge 10 on its axially inner side, thus fixing the honeycomb mesh 1 within the honeycomb mesh fixing ring 2. A threaded connecting ring 11 is provided on the axially inner side of the honeycomb mesh fixing ring 2, with external threads on its outer circumferential surface. The outer diameter of the threaded connecting ring 11 is smaller than the outer diameter of the honeycomb mesh fixing ring 2, and its inner wall is flush with the outer edge of the first inner ring retaining edge 9.

[0025] It is easy to see that, compared with the existing honeycomb hood assemblies for sights shown in Figures 1 and 2, the honeycomb hood assembly for sights provided in this embodiment, as shown in Figure 7, eliminates the need for a connecting ring 3. It can be directly threaded to the lens front pressure ring 4 via the threaded connecting ring 11 on the honeycomb mesh fixing ring 2, reducing the number of assembly components and shortening the overall assembly length, resulting in a more compact structure and simplified assembly. Furthermore, the honeycomb mesh pressure ring 7 is fastened to the inner ring of the honeycomb mesh fixing ring 2 through a snap-fit ​​structure located on its axial outer periphery, enabling disassembly and assembly without the need for special tools. It can be operated by hand, which is highly beneficial for field disassembly and assembly, greatly improving ease of use.

[0026] Meanwhile, to facilitate operation, the surface of the honeycomb mesh fixing ring 2 provided in this embodiment is provided with a mesh pattern to improve the friction and stability of operation.

[0027] The snap-fit ​​structure includes multiple male snaps 12 evenly distributed circumferentially on one side of the honeycomb mesh fixing ring 2 facing the first inner ring flange 9, as shown in Figure 3, and corresponding matching annular grooves or female snaps 13 provided on the inner ring wall of the honeycomb mesh fixing ring 2. Each male snap 12 includes multiple circumferentially evenly distributed spring pieces 14 fixedly connected to the honeycomb mesh fixing ring 7, and an arc-shaped protrusion 15 formed on the outer wall of the free end of the spring piece 14. During the process of the honeycomb mesh fixing ring 7 being pushed into the honeycomb mesh fixing ring 2 by external force, the spring piece 14 is compressed and deformed towards the radial center by the arc-shaped protrusion 15 under its own elasticity. When the arc-shaped protrusion 15 moves to the annular groove or female snap 13, the arc-shaped protrusion 15 disengages from the circumferential side wall of the honeycomb mesh fixing ring 2 and is no longer subjected to radial compression force. Meanwhile, the spring piece 14 itself... Under the action of elastic restoring force, the arc-shaped protrusion 15 is pressed into the annular groove or the female buckle 13 to complete the compression and sealing of the honeycomb mesh 1. When it is necessary to disassemble the honeycomb mesh 1, it is pushed outward with the help of external force. Under the action of the arc-shaped guide surface of the arc-shaped protrusion 15, when the external force exceeds the critical value, the component force generated by the guide surface of the arc-shaped protrusion 15 acts on the spring piece 14, causing the spring piece to deform and shrink in the radial direction. Then, under the action of thrust, it slides outward along the circumferential sidewall of the honeycomb mesh fixing ring 2 until it is separated from the honeycomb mesh fixing ring 2. At this point, the sealing of the honeycomb mesh 1 is released and it can be disassembled.

[0028] Compared with the existing technology that uses a spiral connection, where disassembling or installing the honeycomb mesh 1 requires the use of special tools to wedge the groove on the honeycomb mesh fixing ring 2 and rotate it in the direction of rotation for disassembly or installation, making the operation more cumbersome, the above embodiment does not require any tools. It only requires pushing the honeycomb cover assembly by hand in the direction of disassembly or installation to assemble it onto or detach it from the sight, which is very suitable for the convenience requirements of field operations.

[0029] Finally, it should be noted that the outer surface of the honeycomb mesh fixing ring 2 provided in this embodiment is provided with a mesh pattern to improve the friction and stability during operation.
