[0029] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0030] Referring to Figures 1 - 3 As shown, according to an embodiment of the first aspect of the present application, an adjustable reticle structure is provided, including:

[0031] A lens base 1;

[0032] A reticle 2, the reticle 2 is disposed on the lens base 1;

[0033] An adjusting handwheel 3, the adjusting handwheel 3 is disposed on the lens base 1, the adjusting handwheel 3 is connected to the reticle 2, and rotating the adjusting handwheel 3 can drive the reticle 2 to move axially along the lens base 1.

[0034] The adjustable reticle structure provided by the embodiment of the present application includes a lens base 1, a reticle 2 and an adjusting handwheel 3. The reticle 2 is disposed on the lens base 1 and can be moved axially along the lens base 1 through the control of the adjusting handwheel 3. This enables the reticle 2 to be precisely adjusted according to the needs of different vision groups, greatly improving the applicability of the telescope. Whether it is a user with myopia, hyperopia or normal vision, they can rotate the adjusting handwheel 3 to adjust the reticle 2 to the most suitable position for their own observation, thereby obtaining a clear field of view and accurate aiming.

[0035] The adjusting handwheel 3 is connected to the reticle 2, and the rotation of the handwheel can be converted into the axial movement of the reticle 2. The adjusting handwheel 3 has a suitable size and shape for easy holding and operation by the user. At the same time, the rotation of the adjusting handwheel 3 can achieve a small adjustment of the movement of the reticle 2 to meet the precise needs of different vision groups.

[0036] It can be understood that through the setting of the adjusting handwheel 3 and the reticle 2, personalized adjustment can be made according to the vision of the user, improving the convenience and comfort of use. Secondly, the situation where the scale lines of the reticle 2 are inclined in the field of view is effectively avoided. Since the reticle 2 can be precisely adjusted through the adjusting handwheel 3, it can ensure that the scale lines always remain in the correct position, improving the visual experience and usage effect.

[0037] In practical applications, this adjustable reticle structure can be widely applied to various types of telescopes. Whether it is a military telescope, a civilian telescope or a professional observation telescope, by adopting this structure, the performance and applicability of the telescope can be improved. At the same time, it also brings convenience to the manufacture and maintenance of the telescope, reducing the cost and difficulty.

[0038] The reticle 2 includes:

[0039] Bottom plate 21;

[0040] Plate frame 22, a plurality of the plate frames 22 are arranged at intervals on the bottom plate 21, a relief groove is formed on the lens holder 1 at a position matching the plate frame 22, and the plate frame 22 is threadedly connected with the adjusting handwheel 3 through the relief groove.

[0041] In this technical solution, the bottom plate 21 provides stable support for the plate frame 22. The relief groove formed on the lens holder 1 is closely matched with the plate frame 22, providing guidance and limiting functions for the movement of the plate frame 22. The relief groove can ensure that the plate frame 22 moves smoothly therein without shaking or deviation. The plate frame 22 is threadedly connected with the adjusting handwheel 3 through the relief groove, so that the rotation of the adjusting handwheel 3 can be accurately converted into the axial movement of the plate frame 22. The threaded connection has a self-locking function, which can keep the position of the reticle 2 stable after adjustment and will not be easily changed by external forces. The user can rotate the adjusting handwheel 3 to realize the overall adjustment of the reticle 2, which can meet the personalized needs of different vision people for the position of the reticle 2, and can also be adjusted according to different observation conditions to improve the observation effect of the telescope.

[0042] External threads are formed on the outer side of the plate frame 22, and internal threads are formed on the inner side of the adjusting handwheel 3.

[0043] In this technical solution, the external threads on the outer side of the plate frame 22 cooperate with the internal threads on the inner side of the adjusting handwheel 3, so that the rotation of the adjusting handwheel 3 can be converted into the linear movement of the plate frame 22, thereby realizing the fine adjustment of the position of the reticle 2 and providing a better observation experience for the user.

[0044] The number of the plate frames 22 is at least two.

[0045] In this technical solution, the setting of a plurality of plate frames 22 increases the connection points between the reticle 2, the lens holder 1 and the adjusting handwheel 3, so that the installation of the reticle 2 on the lens holder 1 is more stable. During the use of the telescope, it may be affected by various external forces, such as vibration, collision, etc. A plurality of plate frames 22 can evenly share these external forces to ensure that the reticle 2 will not be displaced or deformed due to external forces, ensuring the stability and reliability of the reticle 2.

[0046] At the same time, a plurality of plate frames 22 also provide more stability for the adjustment of the reticle 2. Since each plate frame 22 is threadedly connected with the adjusting handwheel 3, when the adjusting handwheel 3 is rotated, a plurality of plate frames 22 can be driven to move simultaneously, improving the adjustment stability.

[0047] In practical applications, according to different telescope models and usage requirements, the number of frame plates 22 can be adjusted flexibly. For example, for large telescopes or occasions that require high-precision observations, the number of frame plates 22 can be increased to improve the stability and adjustment accuracy of the reticle 2. For small telescopes or general observation requirements, the number of frame plates 22 can be appropriately reduced to lower costs and simplify the structure.

[0048] The reticle 2 further includes:

[0049] A plate body 23;

[0050] A fixed retaining ring 24, and the plate body 23 is arranged in the bottom plate 21 through the fixed retaining ring 24.

[0051] In this technical solution, the plate body 23 is the core part of the reticle 2, on which precise division mil lines are engraved to provide a reference for the user to observe and aim. The plate body 23 is usually made of a material with a high light transmittance to ensure that the scale lines can be clearly presented in the telescope without affecting the observation effect. At the same time, the material of the plate body 23 also has good wear resistance and corrosion resistance, and can maintain the clarity and accuracy of the scale lines during long-term use. The fixed retaining ring 24 serves to firmly fix the plate body 23 in the bottom plate 21. The fixed retaining ring 24 is usually made of a material with a certain elasticity and strength, and can closely fit the plate body 23 and the bottom plate 21 to prevent the plate body 23 from loosening or displacing during use. In addition, the fixed retaining ring 24 can also play a certain protective role. It can prevent impurities such as dust and moisture from entering the gap between the plate body 23 and the bottom plate 21, thereby protecting the plate body 23 from the influence of the external environment. At the same time, the fixed retaining ring 24 can also buffer the external impact force to a certain extent and reduce the damage to the plate body 23.

[0052] It further includes a handwheel retaining ring 6, the handwheel retaining ring 6 is arranged on the lens base 1, and the handwheel retaining ring 6 is located on the side of the adjusting handwheel 3 away from the reticle 2.

[0053] In this technical solution, the handwheel retaining ring 6 is installed on the lens base 1 and is located on the side of the adjusting handwheel 3 away from the reticle 2. It can effectively limit the axial movement of the adjusting handwheel 3 and prevent it from accidentally loosening or falling off during use. The handwheel retaining ring 6 is used to fix the adjusting handwheel 3 on the lens base 1.

[0054] In actual use, when the user rotates the adjusting handwheel 3 to adjust the position of the reticle 2, the handwheel retaining ring 6 can bear the axial force generated by the adjusting handwheel 3 to ensure that the adjusting handwheel 3 always remains in the correct position. At the same time, the handwheel retaining ring 6 can also play a certain dust-proof and waterproof role to prevent external dust and moisture from entering the inside of the lens base 1 and affecting the performance and service life of the reticle 2.

[0055] It also includes a first sealing ring 4 and a second sealing ring 5, and the first sealing ring 4 and the second sealing ring 5 are arranged between the adjusting handwheel 3 and the lens base 1.

[0056] In this technical solution, during the use of the optical instrument, the waterproof performance is crucial. Especially in some harsh environments, such as humid, rainy or places where water may be contacted, good waterproof measures can protect the precision components inside the optical instrument from being eroded by water. The first sealing ring 4 and the second sealing ring 5 are arranged between the adjusting handwheel 3 and the lens base 1, forming a double waterproof barrier.

[0057] The first sealing ring 4 is usually made of a rubber material with high elasticity and good sealing performance. It closely fits on the contact surface between the adjusting handwheel 3 and the lens base 1, and can effectively prevent moisture from seeping into the optical instrument from the outside. Even when under a certain pressure or impact force, the first sealing ring 4 can still maintain good sealing performance to ensure that moisture cannot enter.

[0058] The second sealing ring 5 serves as another line of defense, further enhancing the waterproof effect. It cooperates with the first sealing ring 4 to perform sealing and waterproofing from the upper and lower sides. When moisture attempts to enter the optical instrument through the gap between the adjusting handwheel 3 and the lens base 1, the first sealing ring 4 and the second sealing ring 5 can effectively block the further penetration of moisture. At the same time, the second sealing ring 5 can also play a buffering role, reducing the impact of the adjusting handwheel 3 on the lens base 1 during use, thereby extending the service life of the optical instrument.

[0059] It can be understood that the provision of the first sealing ring 4 and the second sealing ring 5 provides reliable waterproof protection for the optical instrument. They effectively prevent the intrusion of moisture, protect the precision components inside the optical instrument, and ensure that the optical instrument can work normally in various environments. It improves the reliability and durability of the optical instrument, providing a better user experience for users.

[0060] The second aspect embodiment of this application provides an eyepiece, and the eyepiece includes a lens body 7, an eyepiece retaining ring 8 and the adjustable reticle structure provided in any of the above embodiments. The adjustable reticle structure is arranged in the lens body 7 through the eyepiece retaining ring 8. Thus, it has all the beneficial technical effects of this adjustable reticle structure, which will not be elaborated here.

[0061] In this technical solution, the adjustable reticle structure is installed on the lens body 7 through the eyepiece retaining ring 8 to fix the adjustable reticle 2.

[0062] A third sealing ring 9 is arranged between the lens base 1 and the lens body 7.

[0063] In this technical solution, in the structure of the eyepiece, the connection part between the lens base 1 and the lens body 7 is a potential risk point for water intrusion. In order to effectively prevent moisture from seeping into the interior of the eyepiece from this part, the third sealing ring 9 plays a key role. The third sealing ring 9 is usually made of a high-performance waterproof sealing material, with excellent elasticity and sealing performance.

[0064] When the lens base 1 is tightly connected to the lens body 7, the third sealing ring 9 is squeezed between the two, forming a tight waterproof barrier. It can closely fit the surfaces of the lens base 1 and the lens body 7, preventing moisture from entering the interior of the eyepiece through any tiny gaps. Even when facing the challenges of external water pressure or a humid environment, the third sealing ring 9 can maintain its sealing performance, ensuring that the internal components of the eyepiece are not damaged by moisture.

[0065] To ensure the reliability of the waterproof effect of the third sealing ring 9. First of all, its size and shape are precisely designed to adapt to the connection structure between the lens base 1 and the lens body 7 to achieve the best sealing effect. Secondly, the material of the sealing ring has good corrosion resistance and aging resistance, and can maintain stable performance during long-term use. In addition, during the installation process, the third sealing ring 9 is correctly positioned and fixed to ensure that it will not shift or deform during use.

[0066] In practical applications, the third sealing ring 9 provides strong protection for the use of the eyepiece in various harsh environments. Whether in a humid laboratory environment, outdoors on a rainy day or other occasions where water may be encountered, the eyepiece can rely on the waterproof function of the third sealing ring 9 to keep the interior dry and clean, ensuring the stability and reliability of the optical performance.

[0067] When the telescope is in different environmental conditions, such as high temperature, low temperature, humidity, etc., the third sealing ring 9 can maintain its sealing performance, ensuring the stability of the internal optical system. The third sealing ring 9 can also prevent dust and fine particles from entering the interior of the telescope, reducing wear and pollution of the optical elements.
