[0002] The lens is one of the most important parts of a camera, it is responsible for capturing light and focusing it onto the camera's photosensitive element to create an image.

[0003] For example, the Chinese utility model patent with publication number "CN210323720U" discloses a space remote sensing camera lens with a protective function. The utility model rotates the protective cover to a side away from the end of the lens barrel through a rotation connection between the first lug and the second lug to take pictures. When the camera is not in use, the user can rotate the protective cover to the end of the lens barrel to cover the lens inside the lens barrel, thereby preventing the lens from being scratched.

[0004] In the above patent, the lens can be protected from being scratched, but when the device is used, the protective cover needs to be continuously turned to adjust the position of the protective cover so that the protective cover is separated from the lens. After use, the protective cover needs to be turned back to the original position to protect the lens. The process is time-consuming and inconvenient to use the lens. Utility Model Content

[0026] Reference Figure 1 and Figure 2The embodiment of the present application provides a lens with a protective function, including a mounting tube 1 for mounting a device, a protective mechanism 2 for protecting the lens from dust is arranged on the surface of the mounting tube 1, and a shock absorbing mechanism 3 for shock absorbing the lens is arranged on the surface of the mounting tube 1; the protective mechanism 2 includes a connecting block 201, a telescopic rod 202, a hemispherical body 203 and a sliding ring 206, the connecting block 201 is fixedly mounted on the surface of the mounting tube 1, the telescopic rod 202 is fixedly mounted on the inner wall surface of the connecting block 201, the hemispherical body 203 is fixedly mounted on one end of the telescopic rod 202, and the sliding ring 206 is slidably connected to the surface of the mounting tube 1, and the protective mechanism 2 can be used to pull the sliding ring 206 to slide to the inner wall surface of the connecting block 201 when the lens needs to be used, and the limiting rod 205 can limit the sliding ring 206 to prevent it from rotating when sliding, and at the same time the sliding ring 206 squeezes the hemispherical body 203 The spring 204 drives the telescopic rod 202 and the spring 204 to retract. When the notch provided on the surface of the sliding ring 206 is perpendicular to the hemispherical body 203, the spring 204 rebounds and drives the hemispherical body 203 to slide to the inner wall of the notch to limit the sliding ring 206. When the sliding ring 206 slides, it drives the dust cover 207 to rotate and move to separate from the lens. After use, the sliding ring 206 is pushed to reset it. The magnet block 208 on one side of the dust cover 207 and the magnet block 208 at one end of the sliding ring 206 are attracted to limit the dust cover 207 so that the dust cover 207 protects the lens. The shock absorbing mechanism 3 can reduce the impact on the lens by first contacting the rubber block 301 with the ground to avoid damage to the lens. The rotating block 302 is rotated to rotate the threaded block 303 to drive the other rubber block 301 to move. After it is separated from the threaded block 303, the two rubber blocks 301 can be removed from the device for replacement.

[0027] Reference Figure 2 and Figure 3 In one aspect of this embodiment, a spring 204 is fixedly installed on the inner wall surface of the connecting block 201 , and the other end of the spring 204 is fixedly connected to the hemisphere 203 , and the spring 204 is movably wound around the surface of the telescopic rod 202 .

[0028] A limiting rod 205 is fixedly mounted on the surface of the mounting tube 1 , and a sliding ring 206 is slidably connected to the surface of the limiting rod 205 .

[0029] A dust cover 207 is hinged at one end of the sliding ring 206, and a magnet block 208 is fixedly installed on one side of the dust cover 207 and one end of the sliding ring 206. When the lens needs to be used, the sliding ring 206 is pulled to slide to the inner wall surface of the connecting block 201, and the limiting rod 205 can limit the sliding ring 206 to prevent it from rotating when sliding. At the same time, the sliding ring 206 squeezes the hemispherical body 203 to drive the telescopic rod 202 and the spring 204 to retract. When the slot is perpendicular to the hemisphere 203, the spring 204 rebounds and drives the hemisphere 203 to slide to the inner wall of the slot to limit the sliding ring 206. When the sliding ring 206 slides, it drives the dust cover 207 to rotate and move to separate from the lens. After use, the sliding ring 206 is pushed to reset it. The magnet block 208 on one side of the dust cover 207 and the magnet block 208 at one end of the sliding ring 206 attract each other to limit the dust cover 207 so that the dust cover 207 protects the lens.

[0030] Reference Figure 1 and Figure 4 In one aspect of this embodiment, a rubber block 301 is slidably connected to the inner wall surface of the sliding ring 206 , and there are two rubber blocks 301 . A rotating block 302 is rotatably connected to one side of the inner wall of the rubber block 301 .

[0031] A threaded block 303 is fixedly installed at one end of the rotating block 302. The threaded block 303 is threadedly connected to the inner wall surface of the rubber block 301. The rubber block 301 first contacts the ground to reduce the impact on the lens and avoid damage to the lens. The rotating block 302 is rotated to rotate the threaded block 303 to drive the other rubber block 301 to move. After it is detached from the threaded block 303, the two rubber blocks 301 can be removed from the device for replacement.

[0032] All electrical equipment in this solution are powered by an external power supply.

[0033] Working principle: When the device is used, the mounting tube 1 should be mounted on the lens surface first. When the lens needs to be used, the sliding ring 206 is pulled to slide to the inner wall surface of the connecting block 201. The limiting rod 205 can limit the sliding ring 206 to prevent it from rotating when sliding. At the same time, the sliding ring 206 squeezes the hemisphere 203 to drive the telescopic rod 202 and the spring 204 to retract. When the notch opened on the surface of the sliding ring 206 is perpendicular to the hemisphere 203, the spring 204 rebounds and drives the hemisphere 203 to slide to the inner wall of the notch to limit the sliding ring 206. When the sliding ring 206 slides, it drives the anti-rotation rod 202 to retract. The dust cover 207 rotates and moves to detach from the lens. After use, the sliding ring 206 is pushed to reset it. The magnet block 208 on one side of the dust cover 207 and the magnet block 208 at one end of the sliding ring 206 attract each other to limit the dust cover 207 so that the dust cover 207 protects the lens. When the device accidentally falls, the rubber block 301 first contacts the ground to reduce the impact on the lens to avoid damage to the lens. The rotating block 302 is rotated to rotate the threaded block 303 to drive the other rubber block 301 to move. After it is detached from the threaded block 303, the two rubber blocks 301 can be removed from the device for replacement.
