Description

Technical Field

[0001] This application relates to the field of aiming equipment technology, and in particular to a aiming lens and an aiming device equipped with it. Background Technology

[0002] Currently, scopes are typically mounted on sights used for long-range observation to increase the observation range and facilitate more accurate target acquisition. In related technologies, scope mounting often employs threaded connections, with the scope being installed and removed via rotation. To improve assembly reliability, a relatively large number of thread turns is required, often six or more. This necessitates multiple rotations each time the scope is installed or removed, impacting assembly efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a sight lens that is easy to assemble and disassemble and is highly efficient.

[0004] A sight lens includes a lens mount, a magnifying lens, and an adapter component with a through hole. The adapter component includes an adapter base and an adapter block, the through hole penetrating both the adapter base and the adapter block. One of the adapter base and the adapter block is disposed on the lens mount, and the other is disposed on the magnifying lens. An axial limiting group is provided between the adapter base and the adapter block to limit the position of the adapter base and the adapter block along the optical axis of the magnifying lens. A circumferential limiting group is provided between the adapter base and the adapter block to limit the position of the adapter base and the adapter block around the optical axis of the magnifying lens. The magnifying lens is rotatable relative to the lens mount, and the axial limiting group and / or the circumferential limiting group limit or release the engagement of the adapter base and the adapter block.

[0005] Understandably, the use of axial and circumferential limiting groups not only limits the position of the adapter and adapter block along the optical axis but also limits their position around the optical axis, thus satisfying the bidirectional assembly limiting of the magnifying glass and lens mount in both the optical axis and circumferential directions. During assembly, only the magnifying glass needs to be rotated to engage the axial and circumferential limiting groups; and during disassembly, the magnifying glass is rotated to release the aforementioned limiting. Throughout the assembly and disassembly process, the number of turns is independent, eliminating the need for multiple rotations, making assembly simpler, more reliable, and improving efficiency.

[0006] In some embodiments, the axial limiting assembly includes a snap-fit ​​arm and a limiting groove with a notch, one of which is disposed on the adapter seat and the other on the adapter block, the snap-fit ​​arm being able to rotate into the limiting groove via the notch and snap into the limiting groove.

[0007] In some embodiments, the axial limiting assembly further includes a first elastic element disposed on the adapter block or the adapter seat, for pressing the snap-fit ​​arm against the groove wall of the limiting groove.

[0008] In some embodiments, the first elastic element includes a plurality of elastic arms arranged at intervals around the optical axis, each of the elastic arms being able to abut between the adapter and the adapter block along the optical axis.

[0009] In some embodiments, the first elastic element is disposed on the adapter block, one of the first elastic element and the adapter block is provided with a limiting notch, and the other is provided with a limiting protrusion, the limiting protrusion being engaged at the limiting notch.

[0010] In some embodiments, the snap-fit ​​arm is provided with a first limiting part, and the limiting groove is provided with a second limiting part. The first limiting part and the second limiting part can abut against each other to limit the rotation of the rotating seat and the rotating block.

[0011] In some embodiments, the limiting groove includes a first groove wall and a second groove wall, which are arranged opposite to each other and spaced apart along the optical axis, and the notch is provided in the first groove wall;

[0012] The second limiting part and the notch are arranged at intervals around the optical axis and protrude into the cavity of the limiting groove; and / or, the first limiting part protrudes from the side of the snap-fit ​​arm away from the first groove wall.

[0013] In some embodiments, the adapter is connected to the lens mount and has the limiting groove, the adapter block is detachably connected to the magnifying lens and has the locking arm; multiple locking arms are provided and are arranged at intervals around the optical axis, multiple notches are provided and are arranged at intervals around the optical axis, and the multiple locking arms and multiple notches correspond one-to-one.

[0014] In some embodiments, the circumferential limiting group includes a positioning groove and a positioning post, one of which is disposed on the adapter seat and the other is disposed on the adapter block; during the engagement limiting, the positioning post is inserted into the positioning groove; during the release limiting, the positioning post is removed from the positioning groove.

[0015] In some embodiments, the adapter or the adapter block is provided with an assembly hole; the positioning post includes a post body and a second elastic member, both the second elastic member and a portion of the post body are accommodated in the assembly hole, and the second elastic member is connected between the post body and the wall of the assembly hole to apply a force to the post body toward the outside of the assembly hole.

[0016] In some embodiments, the scope is provided with an assembly cylinder, the adapter block is disposed in the assembly cylinder, and a first sealing ring is pressed between the adapter block and the assembly cylinder; and / or, one of the adapter block and the adapter seat is provided with a second sealing ring, the second sealing ring being pressed between the adapter block and the adapter seat.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0035] Please see Figures 1 to 3 One embodiment of this application provides a sight lens that facilitates quick assembly and disassembly of the magnifying lens 20, resulting in high assembly and disassembly efficiency. The sight lens includes a lens mount 10, a magnifying lens 20, and an adapter component 30. The lens mount 10 can be the base of the sight itself. The magnifying lens 20 is detachably connected to the lens mount 10 via the adapter component 30. When assembled, the optical axis of the magnifying lens 20 is coaxial with the optical axis of the lens mount 10, facilitating accurate target acquisition. The adapter component 30 has a through hole 301 extending along the optical axis to ensure that the field of view of the lens corresponding to the magnifying lens 20 matches the field of view of the lens corresponding to the lens mount 10.

[0036] The adapter component 30 includes an adapter base 31 and an adapter block 32, one of which is located on the lens mount 10 and the other on the magnifying lens 20. The aforementioned through hole 301 passes through both the adapter base 31 and the adapter block 32. That is, the magnifying lens 20 is detached from the lens mount 10 through the mutual cooperation of the adapter block 32 and the adapter base 31. Therefore, both the adapter base 31 and the adapter block 32 are provided with holes that pass through along the optical axis to jointly form the through hole 301 of the adapter component 30, ensuring that the aiming field of view is not interfered with.

[0037] An axial limiting group 33 is provided between the adapter 31 and the adapter block 32 to limit the position of the adapter 31 and the adapter block 32 along the optical axis, i.e., axial limiting; and a circumferential limiting group 34 is provided between the adapter 31 and the adapter block 32 to limit the position of the adapter 31 and the adapter block 32 around the optical axis, i.e., circumferential limiting. The magnifying lens 20 can rotate relative to the lens mount 10 so that the adapter 31 and the adapter block 32 are limited or released by the cooperation of the axial limiting group 33 and the circumferential limiting group 34. For example, when the magnifying lens 20 rotates clockwise relative to the lens mount 10, the adapter 31 and the adapter block 32 are axially limited by the axial limiting group 33 and circumferentially limited by the circumferential limiting group 34, satisfying the assembly of the magnifying lens 20 and the lens mount 10. Conversely, when the magnifying lens 20 rotates counterclockwise relative to the lens mount 10, the circumferential limiting group 34 between the adapter 31 and the adapter block 32 is released, and the axial limiting group 33 is also released as it rotates, thus allowing the magnifying lens 20 to be disassembled relative to the lens mount 10. Alternatively, the magnifying lens 20 can rotate counterclockwise to engage the axial limiting group 33 and the circumferential limiting group 34 for limiting, while clockwise rotation releases the limiting.

[0038] It should be added that the circumferential limiting group 34 is triggered after the scope 20 is rotated to a certain angle. Therefore, after being limited by the circumferential limiting group 34, the scope 20 will no longer rotate in the rotation limiting direction. When disassembly is required, simply rotate the scope 20 in the opposite direction.

[0039] Compared to related technologies that utilize threaded connections, the sight lens provided in this embodiment only requires rotating the magnification lens 20 until the axial limiting group 33 and the circumferential limiting group 34 are engaged for limiting, thus achieving bidirectional limiting. Furthermore, when disassembly is required, simply rotate in the opposite direction to release the aforementioned two limiting mechanisms. Throughout the entire assembly and disassembly process, the number of spiral turns is not critical, eliminating the need for multiple rotations each time, making assembly simpler, more reliable, and improving assembly and disassembly efficiency.

[0040] like Figures 4 to 6 As shown, the adapter 31 can be integrally formed with the lens mount 10, such as through injection molding. This design reduces assembly steps and further improves assembly efficiency. Simultaneously, the adapter block 32 can be fixed to the lens 20 using screws 35, facilitating the removal and replacement of the adapter block 32 relative to the lens 20. Alternatively, the adapter block 32 and the lens 20 can be snap-fitted together. Of course, the adapter block 32 can also be bonded to the lens 20, integrally formed, etc.

[0041] Alternatively, the adapter 31 can be located on the magnifying lens 20, and the adapter block 32 can be located on the lens mount 10, as long as it satisfies the assembly and disassembly of the magnifying lens 20 relative to the lens mount 10.

[0042] The specific structures of the axial limiting group 33 and the circumferential limiting group 34 are described below.

[0043] Please see Figures 1 to 6 For example, the axial limiting assembly 33 includes a snap-fit ​​arm 331 and a limiting groove 332 with a notch 3321. One of them is located on the adapter 31, and the other is located on the adapter block 32. The snap-fit ​​arm 331 can rotate into the limiting groove 332 through the notch 3321 and snap into the limiting groove 332. That is, the notch 3321 facilitates the snap-fit ​​arm 331 to rotate in or out of the limiting groove 332. Taking the snap-fit ​​arm 331 located on the adapter block 32 as an example, the limiting groove 332 is located on the adapter 31. When the snap-fit ​​arm 331 rotates into the limiting groove 332 through the notch 3321, the snap-fit ​​arm 331 abuts against the groove wall of the limiting groove 332 to satisfy the snap-fit ​​limiting between the snap-fit ​​arm 331 and the limiting groove 332, thereby realizing the axial limiting of the adapter 31 and the adapter block 32 along the optical axis.

[0044] In practical use, taking the snap-fit ​​arm 331 integrally formed into the adapter block 32 as an example, multiple snap-fit ​​arms 331 are provided and arranged at intervals around the optical axis, that is, multiple snap-fit ​​arms 331 are arranged at intervals along the circumference of the adapter block 32. Multiple notches 3321 are also provided on the limiting groove 332 and arranged at intervals along the circumference of the adapter 31, with each snap-fit ​​arm 331 corresponding to one notch 3321. By setting multiple snap-fit ​​arms 331, the limiting area with the limiting groove 332 is increased, thereby improving the connection reliability along the axial direction. During assembly, the magnifying lens 20 can be adjusted relative to the lens mount 10 to the position where each snap-fit ​​arm 331 corresponds to one notch 3321, and then the magnifying lens 20 is rotated so that each snap-fit ​​arm 331 rotates into the limiting groove 332 through its corresponding notch 3321 to satisfy the axial limiting. During rotation, the magnifying lens 20 rotates until it is stopped by the circumferential limiting group 34, at which point the magnifying lens 20 stops rotating, and the connection between the adapter 31 and the adapter block 32 satisfies the assembly of the magnifying lens 20 relative to the lens mount 10. For disassembly, the magnifying lens 20 is rotated in the opposite direction to release the limiting effect of the circumferential limiting group 34, and with this rotation, each locking arm 331 moves to the notch 3321, allowing it to be removed from the corresponding notch 3321, thus achieving disassembly.

[0045] like Figure 2 As shown, the central angle β corresponding to each notch 3321 is greater than the central angle α corresponding to each snap-fit ​​arm 331, which is beneficial for each snap-fit ​​arm 331 to be placed at the notch 3321 so as to rotate into or out of the limiting groove 332 from the notch 3321.

[0046] like Figure 2 , Figure 3 and Figure 10As shown, the latching arm 331 is further provided with a first limiting part 3311, and a second limiting part 3323 is provided in the limiting groove 332. The first limiting part 3311 and the second limiting part 3323 can abut to limit the rotation of the adapter seat 31 and the adapter block 32. That is, by using the cooperation of the first limiting part 3311 and the second limiting part 3323, the rotation angle of the adapter block 32 and the adapter seat 31 can be limited, preventing the rotation angle from being too large and causing the circumferential limiting group 34 to disengage. In actual use, if the user feels that the magnifying lens 20 cannot be rotated with force during the rotation process, it means that the first limiting part 3311 and the second limiting part 3323 are in an abutting state. At this time, it indicates that the rotation angle of the magnifying lens 20 is too large and needs to be rotated in the opposite direction by a certain angle to satisfy the limiting cooperation of the circumferential limiting group 34. Of course, the first limiting part 3311 and the second limiting part 3323 can also be used to indicate whether the rotation is in place. When the two parts come into contact, it means that the rotation is in place. At this time, the circumferential limiting group 34 is triggered to realize circumferential limiting.

[0047] Please continue reading. Figures 1 to 4 In some specific embodiments, the limiting groove 332 includes a first groove wall and a second groove wall arranged opposite to each other along the optical axis, with the second groove wall close to the lens mount 10, and a notch 3321 provided in the first groove wall. Multiple notches 3321 divide the first groove wall into multiple limiting sub-groove walls 3322. Each locking arm 331 rotates via a notch 3321 to the corresponding cavity of each limiting sub-groove wall 3322 and is limited by the limiting sub-groove wall 3322. Each limiting sub-groove wall 3322 is provided with the aforementioned second limiting portion 3323, and each second limiting portion 3323 and each notch 3321 are arranged alternately around the optical axis, with each second limiting portion 3323 located on the same side of the corresponding limiting sub-groove wall 3322 along the circumference of the adapter 31. The limiting groove wall 3322, along the circumference of the adapter block 32 away from the notch 3321, has a second limiting part 3323 protruding along the optical axis, so that the second limiting part 3323 is located in the cavity of the limiting groove 332. The first limiting part 3311 is located on the side of the latching arm 331 away from the adapter seat 31 along the optical axis, that is, the first limiting part 3311 protrudes on the side of the latching arm 331 away from the first groove wall. The first limiting part 3311 is integrally formed with the latching arm 331, and the second limiting part 3323 is integrally formed with the groove wall of the limiting groove 332. In this way, the cooperation of the first limiting part 3311 and the second limiting part 3323 can satisfy the rotation angle limitation; and, this setting can also limit the rotation direction of the magnifying lens 20 relative to the lens mount 10, ensuring that it can only rotate in one direction when assembling and releasing the limitation, thus improving the connection reliability.

[0048] For example, if each first limiting part 3311 is located on the clockwise side of the wall 3322 of the limiting sub-slot along the circumference of the adapter 31, then the magnifying lens 20 rotates clockwise relative to the lens mount 10 to engage with the limiting part, and rotates counterclockwise to release the limiting part. Conversely, it can also be located on the counterclockwise side of the wall 31 along the circumference of the adapter 31, then it rotates counterclockwise to engage with the limiting part, and rotates clockwise to release the limiting part.

[0049] The first limiting part 3311 and the second limiting part 3323 can be fitted together at an angle.

[0050] Furthermore, the circumferential limiting group 34 can be provided on the locking arm 331 at a position close to the first limiting part 3311.

[0051] Please see Figure 1 , Figure 5 , Figure 6 and Figure 9 In some optional embodiments, the axial limiting assembly 33 further includes a first elastic element 333, which is disposed on the adapter block 32 and is used to press the locking arm 331 against the groove wall of the limiting groove 332. During actual assembly, the user holds the magnifying lens 20 to move the locking arm 331 into the limiting groove 332 via the notch 3321. At this time, the user can apply a force along the optical axis towards the lens mount 10 to the magnifying lens 20, causing the first elastic element 333 to be pressed between the adapter 31 and the adapter block 32. Then, the user rotates the magnifying lens 20. Due to the elastic change of the first elastic element 333 itself, the adapter block 32 rotates with the magnifying lens 20 to compress the first elastic element 333, causing it to deform accordingly and reducing rotational interference. When the magnifying lens 20 rotates to the point where the circumferential limiting group 34 is triggered and circumferentially limited, the user removes the force acting on the magnifying lens 20. After the first elastic element 333 loses the aforementioned force along the optical axis, it applies a force along the optical axis away from the adapter seat 31 to the adapter block 32. At this time, because the first groove wall of the limiting groove 332 limits the locking arm 331 along the optical axis, the locking arm 331 is pressed against the first groove wall (i.e., the aforementioned limiting sub-groove wall 3322), thereby improving the connection reliability.

[0052] like Figure 1 , Figures 5 to 7 As shown, the first elastic element 333 further includes a plurality of elastic arms 3331 arranged at intervals around the optical axis, each of the elastic arms 3331 being able to press against the adapter block 32 and the adapter seat 31 along the optical axis. For example, the number of elastic arms 3331 is adapted to the number of snap-fit ​​arms 331, and the plurality of elastic arms 3331 and the plurality of snap-fit ​​arms 331 are staggered along the circumference of the adapter block 32, further improving the connection reliability.

[0053] Each elastic arm 3331 is provided with a wave-shaped bending part to adapt to deformation and press against the adapter block 32 and the adapter seat 31; and this arrangement reduces wear when the magnifying lens 20 rotates.

[0054] like Figure 1 , Figure 6 , Figure 9 and Figure 10 As shown, further, the first elastic element 333 is provided with a through hole 3332 to ensure the field of view of the magnifying lens 20 and the lens mount 10 is connected. The first elastic element 333 can be fixed to the side of the adapter block 32 facing the adapter seat 31 along the optical axis by multiple screws 35. In this case, the adapter block 32 is provided with a threaded hole 303 for engaging with the screws 35. The first elastic element 333 has a fixing part 3333 protruding radially along the through hole 3332 for fixing with the screws 35, which facilitates disassembly and replacement. Of course, the first elastic element 333 can also be connected to the adapter block 32 by a snap-fit ​​or by adhesive, as long as the connection reliability is ensured.

[0055] like Figure 7 As shown, in actual use, one of the first elastic element 333 and the adapter block 32 has a limiting notch 3341, and the other has a limiting protrusion 3342. The limiting protrusion 3342 is engaged with the limiting notch 3341 for initial positioning of the first elastic element 333 relative to the adapter block 32, and then the two are fixed with screws. For example, the first elastic element 333 has a limiting notch 3341 radially recessed outward at the edge of the through hole 3332, and the limiting protrusion 3342 is provided at the corresponding hole edge of the adapter block 32. The limiting protrusion 3342 is inserted into the limiting notch 3341 to achieve initial positioning. Conversely, the adapter block 32 can have a limiting notch 3341, and the first elastic element 333 can have a limiting protrusion 3342.

[0056] Alternatively, the first elastic element 333 can also be located on the side of the adapter facing the adapter block along the optical axis, and its assembly method is similar to that described above, so it will not be repeated here.

[0057] Please see Figure 1 , Figures 4 to 6As another example, the circumferential limiting group 34 includes a positioning groove 341 and a positioning post 342, one of which is located on the adapter 31 and the other on the adapter block 32. When engaging in limiting, the positioning post 342 inserts into the positioning groove 341; when releasing the limiting, the positioning post 342 exits the positioning groove 341. For example, the positioning groove 341 can be located on the adapter 31, and the positioning post 342 on the adapter block 32. Therefore, when the magnifying lens 20 rotates relative to the lens mount 10 until the positioning post 342 is inserted into the positioning groove 341, the circumferential limiting is satisfied; conversely, when the magnifying lens 20 rotates until the positioning post 342 exits the positioning groove 341, the limiting is released. The number of positioning posts 342 corresponds to the number of locking arms 331, with each positioning post 342 corresponding to a positioning groove 341, and the multiple positioning posts 342 and multiple elastic arms 3331 are arranged circumferentially staggered.

[0058] Furthermore, the positioning post 342 includes a post body 3421 and a second elastic element (not shown in the figure), which connects the adapter block 32 and the post body 3421. When the snap-fit ​​arm 331 on the adapter block 32 rotates into the limiting groove 332 via the notch 3321, the second elastic element is compressed. As the magnifying lens 20 rotates until the post body 3421 moves into the positioning groove 341, the elastic potential energy of the second elastic element is released, so that the post body 3421 is confined within the positioning groove 341, achieving circumferential confinement. At the same time, the provision of the second elastic element allows the post body 3421 to have a certain amount of movement along its own axial direction, reducing wear. Alternatively, the positioning post 342 may not include the second elastic element. In this case, both the positioning post 342 and the adapter 31 can be made of rigid materials.

[0059] like Figure 9 and Figure 10 As shown, in actual use, the adapter block 32 may have an assembly hole 302. Parts of the second elastic member and the column 3421 are accommodated within the assembly hole 302, while another part of the column 3421 may protrude from the assembly hole 302, facilitating its engagement with the positioning groove 341. The second elastic member connects the column 3421 to the wall of the assembly hole 302, applying a force towards the outside of the assembly hole 302 to push the column 3421 into the positioning groove 341, achieving circumferential positioning. The column 3421 may include a mating part that engages with the positioning groove 341 and a connecting part for connecting the second elastic member. A limiting end face is provided between the mating part and the connecting part. The second elastic member is sleeved on the connecting part and connected between the connecting part and the wall of the assembly hole 302. This is merely an example.

[0060] Furthermore, the positioning post 342 and the positioning groove 341 are spherically fitted. This arrangement facilitates the movement of the positioning post 342 out of and into the positioning groove 341 as the magnifying lens 20 rotates, and reduces wear. For example, the mating part on the aforementioned post 3421 can be hemispherical, and the positioning groove 341 can be a spherical groove.

[0061] Alternatively, the positioning pin 342 can be located on the adapter 31, and the positioning groove 341 can be located on the adapter block 32. The assembly of the positioning pin 342 on the adapter 31 is basically similar to the assembly on the adapter block 32 described above, and will not be repeated here.

[0062] like Figures 4 to 6 As shown, in some specific embodiments, the positioning posts 342 and positioning grooves 341 are both located on opposite sides of the adapter base 31 and adapter block 32 along the optical axis, which facilitates manufacturing. Alternatively, the positioning posts 342 and positioning grooves 341 can be located circumferentially on the adapter base 31 and adapter block 32. Multiple positioning posts 342, multiple elastic arms 3331, and multiple snap-fit ​​arms 331 are arranged circumferentially in a corresponding manner.

[0063] Please see Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 For example, the magnifying lens 20 is provided with an assembly cylinder 21, and the adapter block 32 is disposed inside the assembly cylinder 21. When the magnifying lens 20 is engaged with the adapter base 31 via the adapter block 32, the assembly cylinder 21 covers the outside of the adapter base 31, so that the engagement point between the adapter block 32 and the adapter base 31 is not exposed, which not only improves aesthetics but also enhances protection. The adapter block 32 has an assembly ring platform 321 on the side opposite to the adapter base 31 along the optical axis. The assembly ring platform 321 is pressed against the end of the magnifying lens 20 and connected to the magnifying lens 20 by screws 35. There is a gap between each snap-fit ​​arm 331 and the assembly ring platform 321, which facilitates the engagement with the first groove wall of the aforementioned limiting groove 332. The circle corresponding to the projected outer contour of each snap-fit ​​arm 331 along the optical axis is smaller than the projected outer contour of the assembly ring platform 321 along the optical axis.

[0064] The screw 35 used to fix the adapter block 32 is longer than the screw 35 used to fix the first elastic member 333. Multiple screws 35 can be provided for each of them, and they are arranged at intervals and staggered along the circumference.

[0065] like Figure 1 , Figure 6 , Figure 8 and Figure 9As shown, after the adapter block 32 is assembled with the assembly cylinder 21 of the magnifying lens 20, a first sealing ring 41 is provided between the adapter block 32 and the assembly cylinder 21 to ensure the sealing of the connection and achieve waterproof and dustproof effects. For example, the first sealing ring 41 can be located on the outer periphery of the assembly ring platform 321, thus achieving a circumferential seal between the adapter block 32 and the assembly cylinder 21. An annular sealing groove is recessed on the outer periphery of the assembly ring platform 321 for assembling the first sealing ring 41. Alternatively, the first sealing ring 41 can be pressed onto the side of the assembly ring platform 321 away from the adapter seat 31 along the optical axis and located near the edge of the outer periphery of the assembly ring platform 321.

[0066] Furthermore, a second sealing ring 42 is provided on one end face of the assembly ring 321 facing the adapter 31 along the optical axis. After the adapter 31 and the adapter block 32 are assembled, the second sealing ring 42 is pressed between the assembly ring 321 and the adapter 31 to ensure the sealing of the connection between the adapter block 32 and the adapter 31, thus achieving waterproof and dustproof effects. The second sealing ring 42 is located as close as possible to the outer edge of the assembly ring 321 to reduce assembly interference between the aforementioned limiting groups and ensure good sealing effect. Of course, the second sealing ring 42 can also be located on the side of the adapter 31 facing the adapter block 32 and within the limiting groove 332.

[0067] Please see Figure 1 , Figure 5 , Figure 6 and Figure 9 In some embodiments, the sight lens further includes a detection component 50 for identifying the Scope 20 model, thereby facilitating the switching to the appropriate Scope 20 program. The Scope 20 program and how to switch between them are existing mature technologies and are not improvements of this application, therefore they will not be described in detail.

[0068] The detection component 50 includes a magnetic body 51 and a Hall plate (not shown in the figure). The Hall plate is connected to the first groove wall of the limiting groove 332, and the magnetic body 51 is connected to the side wall of the adapter block 32 facing the adapter seat 31. When the Hall plate is energized, it can generate electromagnetic induction with the magnetic body 51, thereby satisfying the identification of the magnification lens 20 model. Since the notch 3321 divides the first groove wall into multiple spaced limiting sub-groove walls 3322, a Hall plate can be set at each limiting sub-groove wall 3322, and each Hall plate corresponds to a magnetic body 51. The multiple magnetic bodies 51 are arranged at intervals and staggered from the aforementioned positioning posts 342, etc., to reduce interference.

[0069] like Figure 9 and Figure 10 As shown, the adapter block 32 may have a recessed groove 304 on the side facing the adapter seat 31, and the magnetic body 51 may be embedded in the recessed groove 304 for cooperating with the Hall plate.

[0070] Another embodiment of this application provides a sight device, including the aforementioned sight lens, which facilitates the easy installation and removal of the scope 20 and improves the efficiency of installation and removal.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
