[0045] Example 1

[0046] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a digital camera telescope with adjustable focus, comprising:

[0047] The telescope assembly includes two symmetrically arranged objective tubes 10, a connecting block 20 installed between the two objective tubes 10, an adjustable eyepiece assembly installed on each objective tube 10, an objective module 60 installed on the objective tube 10, and an eyepiece module 70 installed on the adjustable eyepiece assembly.

[0048] The adjustable eyepiece assembly adjusts the focal length between the program lens module 70 and the objective lens module 60.

[0049] A thumb-sized digital camera 80, which is detachably mounted on the connecting block 20; and

[0050] The disassembly structure is installed on the connecting block 20, and the thumb digital camera 80 is disassembled through the disassembly structure.

[0051] In this embodiment, two symmetrically arranged objective lens tubes 10 provide a mounting carrier for the objective lens module 60 and the adjustable eyepiece assembly, and the connecting block 20 realizes the fixed connection of the two objective lens tubes 10, ensuring the overall structure is symmetrical and stable.

[0052] Light from distant objects first enters the objective lens module 60 inside the objective lens tube 10, and after being refracted by the objective lens module 60, it is transmitted to the eyepiece module 70 on the adjustable eyepiece assembly. The user observes distant objects through the eyepiece module 70.

[0053] The adjustable eyepiece assembly can change the distance between the eyepiece module 70 and the objective lens module 60. By adjusting this distance, it can compensate for different object distances or differences in user vision, making the image at the eyepiece module 70 clearer.

[0054] The thumb digital camera 80 can be detachably mounted on the connecting block 20 through a disassembly structure. Its lens is aimed at distant objects, and the scene is recorded in video mode while the user observes through the eyepiece.

[0055] When it is necessary to remove the thumb digital camera 80, the fixing between the thumb digital camera 80 and the connecting block 20 can be released by operating the disassembly structure, so that the camera can be disassembled and used independently.

[0056] In this embodiment, the thumb digital camera 80 is an Airline brand thumb action camera, model HY-V25, with a digital pixel count of 8 million or more.

[0057] Example 2

[0058] like Figures 1-5 As shown, the improvements are based on Example 1:

[0059] Furthermore, one end of each of the two objective lens tubes 10 is an objective lens mounting end 101, and the two objective lens modules 60 are respectively embedded in the inner cavity of the corresponding objective lens mounting end 101.

[0060] Both objective lens tubes 10 have eyepiece docking ends 102 at the ends furthest from the objective lens mounting end 101.

[0061] Both adjustable eyepiece assemblies include external threaded cylinders 40. The outer walls of both external threaded cylinders 40 have external threads, and one end of both external threaded cylinders 40 has a plug-in flange 401. Both external threaded cylinders 40 are plugged into the inner cavity of the corresponding eyepiece docking end 102 through the plug-in flange 401.

[0062] Both adjustable eyepiece assemblies also include an eyepiece tube 50, with an internal thread 501 at one end of the inner wall of each eyepiece tube 50, and a smooth surface 502 at the end of the inner wall of each eyepiece tube 50 away from the internal thread 501.

[0063] Both eyepiece tubes 50 are installed and connected by the threaded engagement between the internal threaded part 501 and the corresponding external threaded part of the external threaded tube 40.

[0064] Both eyepiece modules 70 are embedded in the corresponding light surface 502.

[0065] In this embodiment, the objective lens mounting end 101 provides a precise mounting space for the objective lens module 60, preventing the objective lens module 60 from shaking inside the objective lens barrel 10 and ensuring the stability of light reception.

[0066] The external threaded cylinder 40 is inserted into the eyepiece mating end 102 via the insertion flange 401, thereby achieving the initial positioning of the external threaded cylinder 40 and the objective lens cylinder 10;

[0067] The eyepiece tube 50 is threadedly engaged with the external thread of the external thread cylinder 40 through the internal thread 501. Rotating the eyepiece tube 50 can change its position along the axis of the external thread cylinder 40, thereby precisely adjusting the distance between the eyepiece module 70 and the objective lens module 60 and improving the focus adjustment accuracy.

[0068] The inner wall of the smooth surface 502 provides a stable mounting environment for the eyepiece module 70, preventing the eyepiece module 70 from shifting and ensuring the stability of the imaging optical path.

[0069] Furthermore, both objective lens modules 60 are concentric and coaxial with their corresponding eyepiece modules 70.

[0070] In this embodiment, the objective lens module 60 and the eyepiece module 70 are concentric and coaxial, ensuring that the light rays received from the objective lens module 60 can be transmitted to the eyepiece module 70 along the same straight line, avoiding light deflection that causes image distortion and blurring, and improving the clarity of observation.

[0071] Furthermore, the outer diameters of both insertion flanges 401 are matched with the inner diameters of the corresponding eyepiece mating ends 102.

[0072] In this embodiment, the outer diameter of the insertion flange 401 matches the inner diameter of the eyepiece docking end 102, so that there is no gap after the external threaded cylinder 40 is inserted into the eyepiece docking end 102, preventing the external threaded cylinder 40 from wobbling radially inside the eyepiece docking end 102, ensuring the coaxiality of the external threaded cylinder 40 and the objective lens barrel 10, and thus ensuring the stability of the optical path.

[0073] Furthermore, anti-slip sleeves 30 are fitted onto both ends of the outer walls of the two objective lens tubes 10.

[0074] In this embodiment, the anti-slip sleeve 30 increases the friction between the outer wall of the objective lens barrel 10 and the user's hand, preventing the telescope from slipping due to sweaty hands or uneven force when the user holds the telescope, thus improving safety and grip stability.

[0075] Furthermore, the connecting block 20 is Ω-shaped, with both outer ends being connecting ends 201. Both connecting ends 201 are fixedly installed on the middle of the outer wall of the corresponding objective lens barrel 10.

[0076] In this embodiment, the two connecting ends 201 of the connecting block 20 are respectively fixed to the middle of the outer side wall of the corresponding objective lens barrel 10, so that the tension of the connecting block 20 on the two objective lens barrels 10 is evenly distributed, avoiding deformation of the objective lens barrel 10 due to uneven force, and ensuring the overall structural stability.

[0077] Furthermore, the connecting block 20 has a protrusion in the middle, and an insert groove 202 is provided in the protrusion;

[0078] The thumb digital camera 80 is embedded in one end of the mounting slot 202.

[0079] In this embodiment, the protrusion provides space for the mounting slot 202. The shape of the mounting slot 202 is adapted to the thumb digital camera 80, so that the thumb digital camera 80 is fixed in position after mounting, avoiding the camera from shifting during use, ensuring that the camera lens can accurately aim at distant objects, and ensuring the accuracy of the synchronously recorded images.

[0080] Furthermore, the disassembly structure includes a guide block 90, which is fixedly installed at one end of the mounting slot 202 away from the thumb digital camera 80. The guide block 90 has a guide hole at its center, and a push rod 100 is slidably installed in the guide hole.

[0081] When the push rod 100 slides toward the thumb digital camera 80, the end near the thumb digital camera 80 can abut against the rear side wall of the thumb digital camera 80 and push the thumb digital camera 80 outward to achieve disassembly.

[0082] In this embodiment, the guide hole of the guide block 90 provides sliding guidance for the push rod 100, ensuring that the push rod 100 moves in a straight line toward the thumb digital camera 80;

[0083] When the push rod 100 is pushed, its end abuts against the rear side wall of the thumb digital camera 80 and applies a pushing force, pushing the camera out of the mounting slot 202. Disassembly can be completed without additional tools, making the operation convenient.

[0084] It should be noted that the different embodiments described above can be combined, substituted, and used in combination with each other.

[0085] Work steps:

[0086] like Figures 1-5 As shown, the structure is supported by an Ω-shaped connecting block 20 that fixes two objective lens tubes 10 through a connecting end 201, forming a symmetrical and stable telescope body. The anti-slip sleeves 30 at both ends of the objective lens tubes 10 improve the safety of holding them.

[0087] Scene imaging and observation: Light from distant objects enters the objective lens module 60 in the objective lens mounting end 101 of the objective lens tube 10, and after refraction, it is transmitted along the coaxial path to the eyepiece module 70 in the light part 502 of the eyepiece tube 50. The user observes the scene through the eyepiece module 70.

[0088] Focus adjustment: Rotate the eyepiece tube 50, and its inner threaded part 501 engages with the outer threaded part of the outer threaded tube 40, driving the eyepiece tube 50 to move along the axis of the outer threaded tube 40, changing the distance between the eyepiece module 70 and the objective lens module 60, thereby achieving focus adjustment and ensuring clear imaging (the outer threaded tube 40 is precisely positioned with the eyepiece docking end 102 through the insertion flange 401, ensuring optical path stability during adjustment).

[0089] Synchronous recording: The thumb digital camera 80 is embedded in the mounting slot 202 of the protrusion of the connecting block 20, with the lens pointed at the scene, and records the video simultaneously while the user is observing;

[0090] Camera disassembly: When it is necessary to remove the camera, push the push rod 100 in the guide hole of the guide block 90. ​​The push rod 100 moves in a straight line and abuts against the rear side wall of the thumb digital camera 80, pushing the camera out of the mounting slot 202 to complete the disassembly.

[0091] In summary:

[0092] 1. Achieve the "Observation + Synchronous Video Recording" Function: By installing a thumb digital camera 80 on the telescope connecting block 20, the problem of existing telescopes being able to only observe but not record video synchronously is solved, thus meeting the user's dual needs of "observing + preserving" distant scenery.

[0093] II. High image clarity: 1. The objective lens module 60 and the eyepiece module 70 are concentric and coaxial, ensuring a stable light transmission path and avoiding image shift; 2. The focal length can be precisely adjusted through the threaded engagement of the eyepiece tube 50 and the external threaded tube 40, adapting to different distances of objects and user vision, further improving image clarity.

[0094] III. Strong structural stability: 1. The Ω-shaped connecting block 20 fixes the two objective lens tubes 10 through the connecting end 201, ensuring uniform force distribution and preventing structural deformation; 2. The external threaded cylinder 40 inserts into the flange 401, matching the inner diameter of the eyepiece docking end 102, ensuring a gapless docking between the external threaded cylinder 40 and the objective lens tube 10, thus improving optical path stability; 3. The thumb digital camera 80 is embedded in the mounting slot 202, with a fixed position, preventing image shift during recording.

[0095] IV. High ease of operation: 1. The anti-slip sleeve 30 increases grip friction, making it easy for users to hold the device stably; 2. The disassembly structure allows the thumb digital camera 80 to be pushed out via the push rod 100, requiring no additional tools, making disassembly simple and efficient; 3. The focus can be adjusted by rotating the eyepiece tube 50, and the adjustment method is intuitive and easy to understand.

[0096] V. High versatility and practicality: The thumb digital camera 80 is detachable, allowing users to choose to install or remove the camera according to their needs. It retains the basic observation function of the telescope while expanding the video recording function, adapting to different usage scenarios (such as outdoor observation, event recording, etc.).

[0097] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
