[0001] This invention relates to the field of optical instrument / component technology, and in particular to an automatic protection device for optical instruments / components. Background Technology

[0002] Different components of the same optical instrument, or different optical instruments / components, typically need to be connected via interfaces. When optical instruments / components are disassembled and stored separately, optical lenses or other clean parts near the connection points are exposed to the environment, making them susceptible to contamination, touch, and impact. A common solution is to install protective covers on the connection points, but this step is easily forgotten, and human error before and during the installation of the protective covers can easily damage the optical components. Therefore, this invention provides an automatic protection device for optical instruments / components to solve the above-mentioned technical problems. Summary of the Invention

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0026] Example 1

[0027] See Figure 1 , Figure 4 and Figure 5 An automatic protection device for optical instruments / components includes a protection head body 10, with a first end for connecting to a first optical instrument / component 20 requiring protection, and a second end for connecting to a second optical instrument / component 30 requiring connection to the first optical instrument / component 20. A light channel 13 is provided through the protection head body 10, extending from the first end to the second end. A rotation hole 14 is provided at the second end of the protection head body 10, intersecting with the light channel 13, preferably perpendicular to each other. A valve core 40 is disposed within the rotation hole 14 and rotatably connected to the protection head body 10, blocking the light channel 13. The valve core 40 has a light passage hole 41 that can rotate to communicate with the light channel 13. A trigger-driven reset structure 50 is located at the second end of the protection head body 10, used to drive the valve core 40 to rotate and reset. When the second optical instrument / component 30 is connected to the second end of the protection head body 10, the second optical instrument / component 30 triggers the trigger-driven reset structure 50. In this embodiment, the trigger drive reset structure 50 includes a first elastic element 51 and a trigger ear 52. The trigger ear 52 is disposed on the valve core 40. One end of the first elastic element 51 is connected to the protective head body 10, and the other end is connected to the trigger ear 52.

[0028] Specifically, see Figure 5The protective head body can be configured as a connection of a first column 11 and a second column 12 with different diameters. The central axes of the first column 11 and the second column 12 coincide, and the diameter of the first column 11 is larger than that of the second column 12. It should be noted that the form of the protective head body 10 is not limited to this. The optical channel 13 passes through the first column 11 and the second column 12, and the optical channel 13 is located on the central axis of the first column 11 and the second column 12. The rotating hole 14 is a circular hole and is set on the second column 12. See also Figure 4 The valve core 40 is cylindrical and can rotate within the rotary hole 14. The light passage 41 is arranged radially along the valve core 40. When the light passage 41 rotates with the valve core 40 until its central axis coincides with the central axis of the second column 12, the light passage 41 connects with the light channel 13, and the light channel 13 becomes a pass. The valve core 40 can also rotate to block the light channel 13. The trigger ear 52 is arranged on the circumference of the valve core 40 outside the rotary hole 14 and can rotate with the valve core 40. The first elastic element 51 can be a first spring. One end of the first spring is connected to the trigger ear 52, and the other end is connected to the end face of the first column 11 near the second column 12. The first column 11 is connected to the first optical instrument / component 20 that needs protection, and the second column 12 is connected to the second optical instrument / component 30. It should be noted that those skilled in the art can reasonably connect the first optical instrument / component 20 to the first column 11 using existing technology, and set the connection end of the second optical instrument / component 30 to cooperate with the automatic protection device for optical instruments / components in this embodiment using existing technology, or add a connecting component that cooperates with the automatic protection device for optical instruments / components in this embodiment to the connection end of the second optical instrument / component 30.

[0029] The working principle of the automatic protection device for optical instruments / components in this embodiment is as follows: When the device is connected to the first optical instrument / component 20 that needs protection, the valve core 40 blocks the light channel 13, protecting the optical lenses or other parts requiring cleanliness inside the first optical instrument / component 20. When the second optical instrument / component 30 is connected, the second optical instrument / component 30 pushes the trigger ear 52 on the valve core 40, thereby causing the valve core 40 to rotate. The valve core 40 rotates until the light passage 41 is connected to the light channel 13, and the light channel 13 is a pass, allowing light to pass through. At this time, the first spring is in a compressed state. When the second optical instrument / component 30 is disassembled, under the action of the first spring, the trigger ear 52 drives the valve core 40 to reset, blocking the light channel 13 again, protecting the internal optical lenses, etc.

Example 2

[0031] See Figure 2 and Figure 3The difference between this embodiment and the first embodiment is that the trigger drive reset structure 50 in this embodiment includes a gear part 53, a rack 54 and a second elastic element 55. The gear part 53 is disposed on the valve core 40, the rack 54 is slidably connected to the protective head body 10 and meshes with the gear part 53, one end of the second elastic element 55 is connected to the rack 54 and the other end is connected to the protective head body 10.

[0032] Specifically, a groove 56 can be provided on the first column 11, and a rack 54 is slidably connected to the groove 56. The second elastic element 55 can be a second spring, which is located inside the groove 56. The two ends of the second spring are respectively connected to the groove 56 and the rack 54. Both the rack 54 and the groove 56 are arranged along the extension direction of the optical channel 13. When the second optical instrument / component 30 needs to be connected, the second optical instrument / component 30 pushes the rack 54, and the rack 54 drives the valve core 40 to rotate. The valve core 40 rotates until the light passage 41 is connected to the optical channel 13, and the optical channel 13 is a pass, allowing light to pass through. At this time, the second spring is in a compressed state. When the second optical instrument / component 30 is disassembled, under the action of the second spring, the rack 54 drives the valve core 40 to rotate and reset, blocking the optical channel 13 again and protecting the internal optical lenses, etc.
