DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model will be described in detail below in combination with the drawings and examples.

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] In the description of the utility model, it should be understood that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "aligned", "overlapped", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0024] The terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features; in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0025] The embodiment provides a kind of Figure 3The illustrated sighting device honeycomb cover assembly comprises a honeycomb net 1, a honeycomb net fixing ring 2 and a honeycomb net pressing ring 7, wherein a first inner ring stop 9 is arranged on the outer side of the inner ring of the honeycomb net fixing ring 2 in the axial direction; the honeycomb net pressing ring 7 is connected with the inner ring of the honeycomb net fixing ring 2 through the buckle structure arranged on the peripheral edge of the outer side of the honeycomb net pressing ring 7 in the axial direction, so as to press the honeycomb net 1 on the first inner ring stop 9 through the second inner ring stop 10 arranged on the inner side of the inner ring of the honeycomb net fixing ring 2 in the axial direction, and realize the fixation of the honeycomb net 1 in the honeycomb net fixing ring 2; a threaded connection ring 11 is arranged on the inner side of the honeycomb net fixing ring 2 in the axial direction, and an external thread is arranged on the circumferential outer surface of the threaded connection ring 11; the outer diameter of the threaded connection ring 11 is smaller than the outer diameter of the honeycomb net fixing ring 2, and the inner wall of the threaded connection ring 11 is flush with the outer edge of the first inner ring stop 9.

[0026] As can be seen, the sighting device honeycomb cover assembly provided by the embodiment does not need the connecting ring 3, but can be directly connected with the lens front pressing ring 4 through the threaded connection ring 11 on the honeycomb net fixing ring 2, as shown in Figure 1 , 2 Figure 7 , which reduces the number of assembled components and shortens the overall assembly length, so that the structure is more compact and the assembly is more simplified. Moreover, the honeycomb net pressing ring 7 is connected with the inner ring of the honeycomb net fixing ring 2 through the buckle structure arranged on the peripheral edge of the outer side of the honeycomb net pressing ring 7 in the axial direction, which realizes the disassembly without special tools, and only needs to be operated by hand, which is very beneficial to the field disassembly and greatly improves the simplicity of use.

[0027] Meanwhile, in order to facilitate operation, the surface of the honeycomb net fixing ring 2 is provided with a grid pattern to improve the friction and stability of operation.

[0028] The buckle structure comprises Figure 3 ​The plurality of male buckles 12 shown arranged uniformly in the circumferential direction on the side of the honeycomb net fixing ring 2 facing the first inner ring baffle 9 and the corresponding matching annular groove or female buckle 13 arranged on the inner ring wall of the honeycomb net fixing ring 2. The male buckle 12 includes a plurality of elastic pieces 14 uniformly distributed in the circumferential direction fixedly connected with the honeycomb net fixing ring 7 and an arc-shaped protrusion 15 formed on the outer side wall of the free end of the elastic piece 14. During the process of pushing the honeycomb net fixing ring 7 into the honeycomb net fixing ring 2 by external force, the elastic piece 14 is extruded and deformed to shrink towards the radial center by the arc-shaped protrusion 15 under its own elastic action. When the arc-shaped protrusion 15 moves to the annular groove or female buckle 13, the arc-shaped protrusion 15 is no longer subjected to radial extrusion force by separating from the contact with the circumferential side wall of the honeycomb net fixing ring 2. Under the action of the elastic restoring force of the elastic piece 14, the arc-shaped protrusion 15 is pressed into the annular groove or female buckle 13, completing the extrusion packaging of the honeycomb net 1. When it is necessary to disassemble the honeycomb net 1, the arc-shaped protrusion 15 is pushed outward by external force. Under the action of the arc-shaped guide surface of the arc-shaped protrusion 15, when the external force is greater than the critical value, the component force generated by the arc-shaped guide surface of the arc-shaped protrusion 15 acts on the elastic piece 14, so that the elastic piece deforms and shrinks towards the radial direction. Then, under the action of the pushing force, the elastic piece slides outward along the circumferential side wall of the honeycomb net fixing ring 2 until it is separated from the honeycomb net fixing ring 2. Thus, the packaging of the honeycomb net 1 is released, and the honeycomb net 1 can be disassembled.

[0029] Compared with the prior art of adopting a screw connection, when disassembling or assembling the honeycomb net 1, a special tool is needed to clamp the groove on the honeycomb net fixing ring 2 and rotate in the direction of disassembly or assembly. The operation is relatively troublesome. However, the above embodiment does not need any tool, and only needs to push the honeycomb cover assembly in the direction of disassembly or assembly by hand. The honeycomb cover assembly can be assembled on or disassembled from the sighting device, which is very suitable for the convenience requirement of field operation.

[0030] Finally, it should be noted that the outer ring surface of the honeycomb net fixing ring 2 is provided with a grid pattern to improve the friction and stability of the operation.
