Description

Technical Field

[0001] This utility model relates to the field of telescope technology, specifically to a precision composite focusing mechanism for a telescope. Background Technology

[0002] A telescope is an optical instrument that uses lenses or mirrors and other optical components to observe distant objects. It works by using the refraction of light through a lens or the reflection of light by a concave mirror to make the light enter a small aperture and converge to form an image, which is then seen through a magnifying eyepiece. It is also known as a "telescope".

[0003] A search revealed that the announcement number CN218824895U, entitled "A Hybrid Focusing Monocular Telescope," includes a telescope base. Research and analysis showed that this device, through a positioning and protective mechanism, can protect the connection between the user and the telescope base, increasing comfort when the telescope base and the user are in contact. It also facilitates the fixing of the eyepiece tube and the adjusting tube, reducing the difficulty of fixing the eyepiece tube and the adjusting tube. However, it still has the following drawbacks to some extent.

[0004] For example, the device does not have a defogging function, which can easily cause fog to form inside the device in some environments. This can render the device unusable for a period of time. Furthermore, it is usually not possible to quickly replace telescope components during use, which greatly increases the inconvenience for staff when maintaining the components. To solve the above technical problems, we have designed a precision composite focusing mechanism for telescopes. Utility Model Content

[0021] Please see Figures 1-5 A precision composite focusing mechanism for a telescope includes a telescope housing 1. An eyepiece 2 is fixedly mounted on the left side of the telescope housing 1, and a focusing main tube 3 is movably mounted on the right side of the telescope housing 1. An adjustment mechanism 6 is provided in the inner cavity of the focusing main tube 3, and a focusing tube 7 is movably connected to the inner cavity of the focusing main tube 3. A disassembly and assembly mechanism 8 is provided at the right end of the focusing tube 7. A threaded groove 9 is opened on the right side of the inner cavity of the telescope housing 1, and a threaded ring 10 is fixedly connected to the left end of the focusing main tube 3. The adjustment mechanism 6 includes a protruding shell 11, which is fixedly mounted on the surface of the focusing main tube 3. The disassembly and assembly mechanism 8 includes a groove 18, which is opened in the inner cavity of the focusing tube 7. A battery box 4 is fixedly mounted on the surface of the telescope housing 1, and a power switch 5 is fixedly mounted on the surface of the battery box 4. The cooperation of the threaded groove 9 and the threaded ring 10 facilitates the user to connect the focusing main tube 3 to the telescope housing 1.

[0022] Please see Figure 4 A threaded rod 12 is movably installed in the inner cavity of the protruding shell 11. The right end of the threaded rod 12 extends through to the outside of the protruding shell 11 and is fixedly connected to a torque handle 13. A threaded plate 14 is threadedly fitted on the surface of the threaded rod 12. The bottom of the threaded plate 14 is fixedly connected to the focusing cylinder 7. By setting the torque handle 13, it is convenient for the user to quickly rotate the threaded rod 12, so that the focus of the equipment can be quickly adjusted.

[0023] Please see Figure 4 An electric heating wire 15 is movably connected to the inner cavity of the focusing cylinder 7. A heat insulation sleeve 16 is movably installed on the surface of the electric heating wire 15 and in the inner cavity of the focusing cylinder 7. By setting the heat insulation sleeve 16, the heat emitted by the electric heating wire 15 can be isolated to prevent the temperature from affecting the focusing main cylinder 3 or the focusing cylinder 7.

[0024] Please see Figure 4 A transparent plate 17 is fixedly connected to the inner cavity of the focusing tube 7. The surface of the transparent plate 17 is provided with vent holes. A sealing gasket is fixedly connected to the right end of the focusing tube 7. By setting the transparent plate 17, the inside of the focusing main tube 3 can be sealed to prevent foreign objects from entering the focusing main tube 3 at will. By setting the vent holes, the air circulation inside the equipment can be increased, so that the electric heating wire 15 can also protect the eyepiece 2 from fogging. By setting the sealing gasket, the sealing between the objective lens 25 and the focusing tube 7 can be increased.

[0025] Please see Figure 5 A spring 19 is fixedly connected to the inner cavity of the groove 18, and a ring plate 20 is fixedly connected to the top of the spring 19.

[0026] Please see Figure 5 The inner cavity of the focusing cylinder 7 is provided with a slot 21, and the top of the inner cavity of the groove 18 is provided with a limiting slot 22.

[0027] Please see Figure 1 , Figure 2 and Figure 5 A limiting plate 23 is movably installed in the inner cavity of the slot 21. An objective lens 25 is fixedly connected to the top of the limiting plate 23, and a sealing rubber sleeve 24 is fixedly connected to the bottom of the objective lens 25.

[0028] In use, the user performs remote observation through eyepiece 2 and objective lens 25. If the user needs to adjust the focus of the device during observation, they rotate the screw rod 12 by turning the handle 13. The rotation of the screw rod 12 moves the screw plate 14, which in turn moves the focusing cylinder 7. The focusing cylinder 7 then moves the disassembly / assembly mechanism 8, thereby adjusting the distance between the objective lens 25 and the eyepiece 2 to enable focusing. If the objective lens 25 needs to be replaced or maintained, the user first presses the objective lens 25 downwards to disengage the limiting plate 23 from the limiting slot 22. After the limiting plate 23 disengages, the user rotates the objective lens 25 to fully move the limiting plate 23 into the slot 21. Then, the user pulls the objective lens 25 outwards until the limiting plate 23 is fully engaged. The entire lens 25 is detached from the slot 21 to allow the user to replace and maintain it. When reinstalling the lens 25, the user can directly insert the limiting plate 23 into the slot 21, so that the limiting plate 23 can press the ring plate 20 downward. Then, the user rotates the lens 25 so that the limiting plate 23 can move to the bottom of the limiting slot 22. After that, the user releases the lens 25. After completion, the ring plate 20 will push the limiting plate 23 upward through the rebound force of the spring 19, so that the limiting plate 23 can be locked into the limiting slot 22. At the same time, if fogging occurs inside the device, the user can install the battery into the battery box 4 to power the device. Then, the user can turn on the electric heating wire 15 through the power switch 5 to heat the focusing main tube 3, thereby defogging the device and improving the practicality of the telescope.

[0029] In summary, this precision composite focusing mechanism for the telescope, through the cooperation of the telescope housing 1, eyepiece 2, focusing main tube 3, battery box 4, power switch 5, adjustment mechanism 6, focusing tube 7, disassembly and assembly mechanism 8, threaded groove 9, and threaded ring 10, solves the problems of the lack of defogging function, the easy formation of fog inside the equipment in some environments, and the inability to quickly replace telescope components during use, which greatly increases the inconvenience for staff.
