Description

A type of binoculars photoelectric telescope

[0001] This application claims priority to Chinese Patent Application No. 202520280188.3, ​​filed on February 20, 2025, entitled "Binocular Optical Telescope", and to Chinese Patent Application No. 202520280234.X, filed on February 20, 2025, entitled "Focusing Structure and Telescope", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of optical equipment technology, and in particular to a binoculars photoelectric telescope. Background Technology

[0003] For binoculars, due to their large size, and to simplify the focusing mechanism, current technology often places it on the outside of the objective lens module. However, this design makes one-handed focusing inconvenient. For example, if the focusing mechanism is on the right side of the objective lens, and the user is holding the binoculars with their left hand, they must use their right hand to focus, making one-handed operation impossible in certain scenarios. Furthermore, placing the focusing mechanism on the outside of the objective lens increases the overall size of the binoculars, reducing their portability. Additionally, an externally located focusing mechanism is less resistant to damage from drops or other impacts. Summary of the Invention

[0004] Based on this, this application provides a binoculars photoelectric telescope to improve the problem of inconvenience for users to operate and focus with one hand in the prior art, and to improve the rationality of the layout of the various components of the binoculars photoelectric telescope.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides a binoculars telescope, including a first lens tube and a second lens tube connected together, and a magnification adjustment component and a focusing structure located between the first lens tube and the second lens tube, wherein the operating parts of the magnification adjustment component and the operating parts of the focusing structure are at least partially exposed on the same side of the telescope for operation.

[0007] In one embodiment, the operating part of the magnification adjustment component is a magnification adjustment handwheel, which can rotate around a first rotating shaft to achieve magnification adjustment; and / or,

[0008] The operating part of the focusing structure is a focusing handwheel, which can rotate around the second rotating shaft to adjust the focal length. The first rotating shaft is coaxial or parallel to the second rotating shaft.

[0009] In one embodiment, the magnification adjustment handwheel and the focusing handwheel are arranged sequentially along the optical axis, and the magnification adjustment handwheel is positioned closer to the eyepiece end than the focusing handwheel.

[0010] In one embodiment, a button assembly is also provided on the same side of the binoculars where the magnification adjustment component and the focusing structure are disposed, and the button assembly includes at least one button.

[0011] In one embodiment, the magnification adjustment component and the focusing structure are disposed on the central housing between the first lens barrel and the second lens barrel, and the center line at the maximum distance between the upper and lower surfaces of the central housing is located on one side of the plane containing the center line of the first lens barrel and the center line of the second lens barrel.

[0012] In one embodiment, an eyepiece module and a display module are respectively housed sequentially at one end of the first lens barrel and the second lens barrel, and an objective lens module, a mechanism module, and a main control module are housed at the other end of the first lens barrel or the second lens barrel. The mechanism module is disposed in the optical path of the objective lens module. The focusing structure is connected to the objective lens module or the mechanism module and is used to adjust the distance between the objective lens module and the mechanism module.

[0013] The magnification adjustment component is electrically connected to the main control module and / or the display module, and is used to adjust the magnification of the image output by the display module.

[0014] In one embodiment, a middle shell is further included, which is disposed inside the central axis outer shell and fixedly connected to the central axis outer shell. The middle shell includes a first receiving cavity and a second receiving cavity that are sequentially connected along the optical axis direction. The focusing structure is at least partially located in the first receiving cavity, and the magnification adjustment component is at least partially located in the second receiving cavity.

[0015] In one embodiment, the focusing structure includes a focusing knob assembly and a transmission assembly. One end of the transmission assembly is connected to the focusing knob assembly, and the other end of the transmission assembly is connected to the objective lens module or the mechanism module. The transmission assembly is used to convert the rotation of the focusing knob assembly into its own axial movement, so as to drive the axial movement of the objective lens module or the mechanism module.

[0016] In one embodiment, the transmission assembly includes a first guide rod, a connecting rod, and a connecting rod limiting member, the connecting rod limiting member being used to restrict the rotation of the connecting rod in the circumferential direction; the focusing knob assembly is threadedly connected to the connecting rod to convert the rotation of the focusing knob assembly into axial movement of the connecting rod, one end of the first guide rod is connected to the connecting rod, and the other end of the first guide rod is connected to the objective lens module or the movement module.

[0017] In one embodiment, the transmission assembly further includes a connecting assembly for connecting the first guide rod and the connecting rod. The connecting assembly includes a pressure block and a pressure plate. The pressure block has a receiving cavity, and the pressure plate has a through hole. One end of the first guide rod has a first protrusion inserted into the receiving cavity. The rod of the first guide rod is inserted into the through hole of the pressure plate. The pressure block and the pressure plate are fixedly connected to enable the first guide rod and the connecting assembly to be movably connected.

[0018] In one embodiment, the surface of the first protrusion away from the pressure plate is an outwardly convex spherical surface.

[0019] In one embodiment, the focusing knob assembly includes a focusing handwheel, a support, and a second guide rod. The second guide rod passes through the focusing handwheel and is fixedly connected to it. One end of the second guide rod is inserted into the center hole of the support, and the other end is threadedly connected to the connecting rod.

[0020] In one embodiment, the connecting rod includes a first head, a rod portion, and a second head that are sequentially adjacent to each other. The second head is connected to the first guide rod. The first head is provided with an internal thread, which engages with the external thread of the second guide rod. The rotation of the rod portion is restricted by the connecting rod limiting member, so that when the focusing handwheel rotates, it drives the connecting rod to move axially through the second guide rod.

[0021] In one embodiment, the magnification adjustment component includes a magnification adjustment handwheel and an encoder connected to each other. When the magnification adjustment handwheel is rotated, it drives the encoder to rotate, thereby adjusting the magnification of the image output by the display module.

[0022] In one embodiment, the magnification adjustment assembly further includes an encoder bracket disposed between the magnification adjustment handwheel and the encoder. The encoder has a rotation knob that passes through the encoder bracket and is connected to the magnification adjustment handwheel, so that when the magnification adjustment handwheel rotates, it drives the encoder to rotate together.

[0023] In one embodiment, the objective lens module includes a first objective lens module and a second objective lens module fixedly connected, with the first objective lens module disposed close to the mechanism module; the binoculars also include an objective lens guide tube, which is disposed on the first objective lens module and fixedly connected to the mechanism module, and is also connected to the drive end of the focusing structure.

[0024] In one embodiment, the objective lens guide tube is clearance-fitted with the first objective lens module, and a guide limiting structure is provided between the objective lens guide tube and the first objective lens module. The objective lens guide tube is used to move in a direction closer to or further away from the first objective lens module along the direction defined by the guide limiting structure.

[0025] This application offers at least the following advantages: The binoculars provided by this application place both the focusing structure and the magnification adjustment component between the two tubes, making the overall layout of the binoculars more compact and rational, and reducing its overall size. The focusing structure's placement in the middle of the two tubes allows users to easily adjust the focus with either hand when operating the binoculars with one hand, improving the user experience. Similarly, placing the magnification adjustment component in the middle of the two tubes facilitates one-handed magnification adjustment. Furthermore, by exposing at least part of the operating parts of both the focusing structure and the magnification adjustment component on the same side of the binoculars, users can easily operate and hold the binoculars with one hand. Users can simultaneously perform two adjustments with one hand (e.g., using the right index finger to operate the magnification adjustment component and the middle finger to operate the focusing structure), without frequently switching hand positions, further improving user convenience and making the overall layout of the components more rational. Moreover, placing the focusing structure and magnification adjustment component between the two tubes also improves their impact resistance, preventing damage from drops. Attached Figure Description

[0045] The technical solutions of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the implementation of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] In the description of this application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are used only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] Referring to Figures 1 and 2, the binoculars of this embodiment include a first lens tube 11 and a second lens tube 12 connected together, and a magnification adjustment component 4 and a focusing structure 3 located between the first lens tube 11 and the second lens tube 12. The first lens tube 11 and the second lens tube 12 are arranged side by side for binocular operation. The magnification adjustment component 4 is used to adjust the magnification of the output image, and the focusing structure 3 is used to adjust the focal length. Meanwhile, the operating parts of both the focusing structure 3 and the magnification adjustment component 4 are at least partially exposed on the same side of the binoculars, allowing the user to easily operate and hold the binoculars with one hand. That is, the user can simultaneously perform two adjustments with one hand (e.g., the right index finger operates the operating part of the magnification adjustment component 4, and the middle finger operates the operating part of the focusing structure 3), without frequently switching hand positions, further improving the convenience of user operation and making the overall layout of the components more reasonable.

[0049] One end of the first lens barrel 11 and the second lens barrel 12 respectively houses an eyepiece module 2 and a display module (not shown). The other end of the first lens barrel 11 and / or the second lens barrel 12 houses an objective lens module 5, a mechanism module 6, and a main control module 7. The mechanism module 6 is located in the optical path of the objective lens module 5. A central axis housing 13 can be disposed between the two lens barrels. A magnification adjustment component 4 and a focusing structure 3 are sequentially disposed on the central axis housing 13. The magnification adjustment component 4 is located near the eyepiece module 2 and is connected to the main control module 7 and / or the display module. The module is electrically connected to adjust the magnification of the image output by the display module. In other words, the magnification adjustment component 4 can be directly electrically connected to the main control module 7, which can adjust the magnification based on the angle change signal received from the magnification adjustment component 4. Similarly, the magnification adjustment component 4 can also be directly electrically connected to the display module, allowing the display module to adjust its own magnification directly based on the angle change signal. The focusing structure 3 is connected to the objective lens module 5 or the mechanism module 6 to adjust the distance between them. The distance between the side of the first lens barrel 11 and the second lens barrel 12 furthest from the central axis housing 13 and the magnification adjustment component 4 and focusing structure 3 allows for easy one-handed operation of both components. By placing the focusing structure 3 and the magnification adjustment component 4 on the central axis housing 13 of the telescope, and by compactly and rationally arranging the components within the lens barrel, the overall size of the lens barrel is reduced, facilitating one-handed operation for focusing and magnification adjustment, while also making the overall layout of the telescope more compact and rational. Whether the user uses their left or right hand, they can focus and adjust the magnification with one hand, making it very convenient to use.

[0050] In this application, the operating part of the magnification adjustment component 4 can be a magnification adjustment handwheel 41, which can rotate around a first axis to achieve magnification adjustment; the operating part of the focusing structure 3 can be a focusing handwheel 311, which can rotate around a second axis to achieve focal length adjustment, and the first axis and the second axis are coaxial or parallel. Meanwhile, the magnification adjustment handwheel 41 and the focusing handwheel 311 are arranged sequentially along the optical axis, and to facilitate the linkage between the focusing handwheel 311 and the objective lens module 5 or the mechanism module 6, the focusing handwheel 311 is preferably positioned closer to the objective lens end than the magnification adjustment handwheel 41, that is, the magnification adjustment handwheel 41 is positioned closer to the eyepiece end than the focusing handwheel 311. Of course, in other alternative embodiments, the focusing handwheel 311 can be positioned closer to the eyepiece end, which is not limited here; at the same time, the operating parts of the magnification adjustment component 4 and the focusing structure 3 can also be set in other forms than the handwheel, such as buttons, push rods, etc., as long as magnification adjustment and focal length adjustment can be achieved through operation.

[0051] Considering that the eyepiece is closest to the eye, the thumb naturally rests on the magnification adjustment wheel 41, and can easily reach the focusing wheel 311 by extending it forward. This allows for quick operation of "magnification first, then focusing" or "magnification and fine-tuning simultaneously," without needing to switch hands or look away. Continuous adjustment of magnification and focal length can be completed with just one thumb. Of course, the index finger of one hand can also be used to operate the magnification adjustment wheel 41, and the middle finger to operate the focusing wheel 311. Furthermore, the two wheels share or are parallel to the optical axis, eliminating the need for a side-protruding lever or knob. This allows for a smaller outer diameter of the lens barrel, resulting in a more compact structure. The coaxial / parallel structure also eliminates the risk of optical axis misalignment caused by eccentric adjustment, ensuring binocular image alignment accuracy.

[0052] In addition, a button assembly is provided on the same side of the binoculars where the magnification adjustment component 4 and the focusing structure 3 are located. The button assembly includes at least one button.

[0053] Building upon the aforementioned capabilities, the thumb / index finger of a single hand can continuously perform all actions—"magnification adjustment → focus adjustment → button triggering (range finding / photo taking / video recording / laser switch, etc.)"—without switching hands or removing the eyepiece. This significantly shortens the time from target acquisition to function triggering and improves emergency response speed. Simultaneously, the buttons and handwheel are located on the same side and share the same side cover or rotary sealing interface, reducing the number of openings in the housing, lowering the risk of dust and moisture intrusion, and simplifying internal wiring. The FPC / wiring harness can be routed along the same axial channel, resulting in a shorter assembly tolerance chain. Of course, in other optional embodiments, the button assembly can also be located on the opposite side of the magnification adjustment component 4 and the focus structure 3; this is not a limiting factor.

[0054] In a preferred embodiment, the centerline at the point of maximum distance between the upper and lower surfaces of the central housing 13 is located on one side of the plane containing the centerlines of the first lens tube 11 and the second lens tube 12. That is, one side of the central housing 13 bulges outward relative to the outer surfaces of the two lens tubes on that side, while the other side of the central housing 13 is concave inward relative to the surfaces of the two lens tubes on that side. This concave side facilitates the user's grip on the binoculars. The central housing 13 is not collinear with the two lens tubes, shortening the total length of the first lens tube 11, the central housing 13, and the second lens tube 12, i.e., the width of the binoculars, further reducing the overall size of the optical binoculars and facilitating one-handed operation. The optical binoculars of this embodiment can be a single-light, single-objective binoculars, or other types of binoculars, such as single-light, double-objective binoculars, or double-light, double-objective binoculars.

[0055] Specifically, the two tubes refer to the first tube 11 and the second tube 12, which are two cylindrical shells. The central housing 13 connects the two tubes. The first tube 11, the second tube 12, and the central housing 13 together form the outer shell 1 of the binoculars. Each tube contains an eyepiece module 2 and a display module. The eyepiece module 2 is located outside the display module, closer to the human eye. When the human eye observes, the image observed through the eyepiece module 2 is the image displayed on the display module. At least one tube contains an objective lens module 5 and a matching mechanism module 6 and a main control module 7. The mechanism module 6 can be, for example, an infrared mechanism module or a low-light mechanism module. The mechanism module 6 receives the image from the objective lens module 5 and transmits it to the main control module 7. The main control module 7 processes the image and then transmits it to the display module for display. The focusing structure 3 adjusts the focus by adjusting the distance between the objective lens module 5 and the mechanism module 6. Taking a single-light, single-objective telescope as an example, this application suggests that an objective lens module 5 and its associated mechanism module 6 and main control module 7 can be installed in only one telescope tube. To enhance the functionality of the binoculars and make better use of the internal space of the telescope tube, a rangefinding module 9 and a battery compartment module 10 can be installed in another telescope tube without an objective lens module 5. The rangefinding module 9 is used to measure the distance between the target object and the observer and display it on the display module, and can also be used to indicate the location of the target object. The battery compartment module 10 is used to provide power to the binoculars. The above-described layout of the rangefinding module 9 and battery compartment module 10 is only one specific embodiment. In other embodiments, both can be placed in the other telescope tube simultaneously, or in two separate telescope tubes. The specific placement is not limited.

[0056] As shown in Figures 2 and 3, to facilitate the installation of the focusing structure 3 and the magnification adjustment component 4, a middle shell 8 can be provided inside the central axis housing 13. This middle shell 8 is fixedly connected to the central axis housing 13 and includes a first receiving cavity 81, a connecting cavity 82, and a second receiving cavity 83 arranged sequentially along the optical axis. The first receiving cavity 81 is located on the side away from the eyepiece module 2. Taking the magnification adjustment handwheel 41 being closer to the eyepiece end than the focusing handwheel 311 as an example, the focusing structure 3 is at least partially located in the first receiving cavity 81, and the magnification adjustment component 4 is at least partially located in the second receiving cavity 83. The middle shell 8 facilitates the installation of the focusing structure 3 and the magnification adjustment component 4 and also provides some protection for them. During telescope assembly, the focusing structure 3 and the magnification adjustment component 4 can be installed in the middle shell 8 first, and then the middle shell 8 can be fixedly connected to the central axis housing 13.

[0057] In some embodiments, the focusing structure 3 includes a focusing knob assembly 31 and a transmission assembly. One end of the transmission assembly is connected to the focusing knob assembly 31, and the other end of the transmission assembly is connected to the objective lens module 5 or the mechanism module 6. The transmission assembly is used to convert the rotation of the focusing knob assembly 31 into its own axial movement, so as to drive the axial movement of the objective lens module 5 or the mechanism module 6.

[0058] Specifically, as shown in Figures 4 and 5, in this embodiment, the transmission assembly includes a first guide rod 37, a connecting rod 34, and a connecting rod limiting member 84. The connecting rod limiting member 84 is disposed on the surface of the middle shell 8 near the connecting rod 34. The connecting rod limiting member 84 is used to limit the rotation of the connecting rod 34 in the circumferential direction. The focusing knob assembly 31 is disposed in the first receiving cavity 81. The focusing knob assembly 31 is threadedly connected to the connecting rod 34 to convert the rotation of the focusing knob assembly 31 into the axial movement of the connecting rod 34. That is, by rotating the focusing knob assembly 31, the connecting rod 34 is driven to move towards or away from the eyepiece module 2. One end of the first guide rod 37 is connected to the connecting rod 34, and the other end of the first guide rod 37 is connected to the objective lens module 5 or the mechanism module 6.

[0059] In addition, the transmission assembly also includes a connecting assembly 36 for connecting the first guide rod 37 and the connecting rod 34. One end of the first guide rod 37 is movably connected to the connecting assembly 36, and the other end of the first guide rod 37 is movably connected to the objective lens module 5 or the movement module 6. The connecting assembly 36 is fixedly connected to one end of the connecting rod 34. The movable connection between the first guide rod 37 and the connecting assembly 36 can prevent jamming during focusing, making focusing smoother.

[0060] Specifically, as shown in Figures 5 and 6, in this embodiment, the connecting assembly 36 includes a pressure block 361 and a pressure plate 362. The pressure block 361 has a receiving cavity, and the pressure plate 362 has a through hole. The first guide rod 37 has a first protrusion 371 at one end near the eyepiece module 2 and a second protrusion 372 at the other end away from the eyepiece module 2. The first protrusion 371 is inserted into the receiving cavity, and the rod of the first guide rod 37 is inserted into the through hole of the pressure plate 362. The pressure block 361 and the pressure plate 362 are fixedly connected, sealing the first protrusion 371 within the receiving cavity of the pressure block 361, thus movably connecting the first guide rod 37 and the connecting assembly 36. The side surface of the pressure block 361 near the eyepiece module 2 is fixedly connected to the connecting rod 34. To make the focusing structure 3 more stable and smooth, the first protrusion 371 and the connecting component 36 can be fitted with a clearance, and the axial clearance between the first protrusion 371 and the connecting component 36 along the first guide rod 37 can be no greater than 0.05mm. This clearance setting is reasonable and can improve the backlash accuracy of the focusing knob. To further improve the smoothness of focusing, the surface of the first protrusion 371 away from the pressure plate 362 can be set as an outwardly convex spherical surface. The end of the first guide rod 37 away from the eyepiece module 2 is movably connected to the lens of the movement module 6 or the objective lens module 5 through the second protrusion 372. At this time, the lens can be, for example, the lens closest to the eyepiece module 2 in the objective lens module 5.

[0061] The focusing knob assembly 31 includes a focusing handwheel 311, a support 312, and a second guide rod 313. The focusing handwheel 311 is located within the first receiving cavity 81. The second guide rod 313 passes through the focusing handwheel 311 and is fixedly connected to it. The support 312 is located on the side of the focusing handwheel 311 near the eyepiece module 2, within the connecting cavity 82, and is fixedly connected to the middle shell 8 via a retaining ring 32. The retaining ring 32 is located within the connecting cavity 82, and the support 312 is located within the retaining ring 32. One end of the second guide rod 313 is inserted into the central hole of the support 312, and the other end is threadedly connected to the connecting rod 34. The other end of the second guide rod 313 extends out of the first receiving cavity 81. A limiting adapter block 315 is fixedly provided on the surface of the middle shell 8 away from the eyepiece module 2. A support block 314 is fixedly provided on the limiting adapter block 315. A groove is provided on the support block 314. The second guide rod 313 rests in the groove. The support 312 and the support block 314 support the second guide rod 313, so that the focusing knob assembly 31 can rotate under the support of the two.

[0062] The connecting rod 34 includes a first head 341, a rod portion 343, and a second head 342 connected sequentially. The second head 342 is connected to the connecting assembly 36. The first head 341 has an internal thread that meshes with the external thread of the second guide rod 313. The thread engagement movement is no more than 0.03 mm, and the number of thread turns and the lead must meet the front and rear focusing margin requirements of the objective lens module 5. The connecting rod 34 is located outside the middle shell 8. A connecting rod limiting member 84 is provided on the surface of the middle shell 8 near the connecting rod 34. The rod portion 343 is located in the connecting rod limiting member 84 so that when the focusing handwheel 311 rotates, it drives the connecting rod 34 to move towards or away from the eyepiece module 2 via the second guide rod 313. When the focusing handwheel 311 is rotated, the focusing handwheel 311 drives the second guide rod 313, which is fixedly connected to it, to rotate together. When the second guide rod 313 rotates, the rotation of the connecting rod 34, which is threaded to it, is restricted by the connecting rod limiting member 84. Therefore, the connecting rod 34 can only move linearly in the direction of approaching or moving away from the eyepiece module 2, thereby driving the first guide rod 37 to move, and finally realizing the focusing function.

[0063] In some embodiments, the connecting rod limiting member 84 can be a guide groove. The guide groove is provided on the surface of the middle shell 8 near the connecting rod 34. The guide groove is used to restrict the rotation of the connecting rod 34 in the circumferential direction, so that the connecting rod 34 can only move linearly in the direction of approaching or moving away from the eyepiece module 2, thereby realizing the focusing function.

[0064] As shown in Figures 2, 4, and 7, the objective lens module 5 includes a first objective lens module 51 and a second objective lens module 52 fixedly connected, for example, through a threaded connection. The first objective lens module 51 is positioned close to the mechanism module 6. The binoculars also include an objective lens guide tube 33, which covers the first objective lens module 51 and is fixedly connected to the mechanism module 6, while also being connected to the drive end of the focusing structure 3. The objective lens module 5 is divided into two components (the first objective lens module 51 and the second objective lens module 52) for ease of installation. The objective lens guide tube 33 is provided to facilitate the movement of the mechanism module 6, making focusing more stable and reliable. The objective lens guide tube 33 is clearance-fitted with the first objective lens module 51. A guide limiting structure is provided between the objective lens guide tube 33 and the first objective lens module 51. For example, the guide limiting structure can be a locating pin and a sliding groove that work together. For instance, a sliding groove is provided on the first objective lens module 51, and a corresponding locating pin is provided on the objective lens guide tube 33. The height of the objective lens guide tube 33 can be appropriately adjusted, and the length of the locating pin can be adjusted accordingly, increasing the mating length between the locating pin and the sliding groove, making the guidance of the guide limiting structure more stable and reliable. The objective lens guide tube 33 is used to move in the direction defined by the guide limiting structure toward or away from the first objective lens module 51.

[0065] As shown in Figures 4 and 6, for example, a limiting block 35 can be set, and a protruding connecting lug 331 can be set on the objective lens guide tube 33. The connecting lug 331 has an opening groove, the radial dimension of which is not less than the radial dimension of the middle rod of the first guide rod 37. The limiting block 35 has a limiting blind hole, the diameter of which is larger than the radial dimension of the second protrusion 372 of the first guide rod 37. The second protrusion 372 is located in the limiting blind hole, and the rod of the first guide rod 37 is inserted into the opening groove. The limiting block 35 is fixedly connected to the connecting lug 331, thereby movably connecting the first guide rod 37 and the objective lens guide tube 33, that is, movably connecting the first guide rod 37 and the mechanism module 6.

[0066] As shown in Figure 5, the magnification adjustment assembly 4 includes a magnification adjustment handwheel 41 and an encoder 44 connected to each other. When the magnification adjustment handwheel 41 rotates, it drives the encoder 44 to rotate, thereby adjusting the magnification of the image output by the display module. The encoder 44 is fixed on the central shaft housing 13, and the side of the encoder 44 with the rotating knob is positioned closer to the objective lens module 5. The encoder 44 is installed upside down, which facilitates the installation with the magnification adjustment assembly 4 and makes the circuit connection more convenient. The magnification adjustment handwheel 41 is located in the second receiving cavity 83. When the magnification adjustment handwheel 41 rotates, it drives the rotating knob to rotate as well. The magnification adjustment handwheel 41 can be fixedly connected to the rotating knob of the encoder 44 or form a snap-fit ​​or limit connection, as long as rotating the magnification adjustment handwheel 41 can drive the rotating knob to rotate simultaneously. To facilitate and ensure the stable installation of the encoder 44, an encoder bracket 43 can be provided. The encoder bracket 43 is located between the magnification adjustment handwheel 41 and the encoder 44, and is sealed in the through hole at the end of the middle shell 8 near the eyepiece module 2. The rotation knob of the encoder 44 passes through the encoder bracket 43 and is connected to the magnification adjustment handwheel 41. When the magnification adjustment handwheel 41 rotates, it drives the encoder bracket 43 and the rotation knob to rotate together.

[0067] Manual magnification adjustment can be achieved by rotating the magnification adjustment handwheel 41. For more flexible magnification adjustment options, an electronic magnification adjustment mode can also be used. As shown in Figure 2, for example, adjustment buttons 42 can be installed on the central shaft housing 13 on both sides of the magnification adjustment handwheel 41. These buttons 42 are electrically connected to the main control module 7. When the adjustment button 42 is pressed, it transmits an adjustment signal to the main control module 7, which then controls the rotation knob of the encoder 44 to achieve automatic magnification adjustment. Alternatively, the power switch and menu buttons can also be located on both sides of the magnification adjustment handwheel 41 for easy operation. The magnification adjustment component 4 and the focusing structure 3 are both located between the two telescope tubes, facilitating user operation and making the overall structure of the telescope more compact and rational.

[0068] As shown in Figures 4 and 5, to improve the waterproof effect of the telescope, some sealing components 100 can also be set. For example, a first sealing ring 101 can be set between the objective lens module 5 and the corresponding lens barrel. Specifically, the first sealing ring 101 is set on the outer wall of the objective lens module 5, and the objective lens module 5 is pressed against the corresponding lens barrel through the first sealing ring 101 to achieve waterproofing between the objective lens module 5 and the outer shell 1. A second sealing ring 102 is provided in the focusing knob assembly 31. For example, the second sealing ring 102 can be set between the second guide rod 313 and the focusing handwheel 311. Specifically, the second sealing ring 102 is set on the outer wall of the second guide rod 313, and the second guide rod 313 is pressed against the focusing handwheel 311 through the second sealing ring 102 to achieve waterproofing of the focusing knob assembly 31. A third sealing ring 103 is provided between the magnification adjustment component 4 and the focusing structure 3. Specifically, the third sealing ring 103 is located on the surface of the focusing handwheel 311 away from the eyepiece module 2. The focusing handwheel 311 is press-fitted with the fixing ring 32 through the third sealing ring 103, thereby achieving the adjustment feel of the encoder 44's rotation knob and compensating for assembly and fitting gaps. A fourth sealing ring 104 is provided between the focusing knob assembly 31 and the middle shell 8. The fourth sealing ring 104 is located on the surface of the focusing handwheel 311 away from the eyepiece module 2. The focusing knob assembly 31 is press-fitted with the middle shell 8 through the fourth sealing ring 104, thereby achieving waterproofing.

[0069] The binoculars in this embodiment optimize the layout of each component, achieving a reasonable arrangement that makes the overall structure more compact, making it more convenient for users to operate, and also improving the stability and reliability of the system.
