[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please refer to Figures 1 to 4. This utility model provides a technical solution: a protective structure for an industrial camera lens used for vision, including a camera body 1, a lens barrel 2 mounted on one side of the camera body 1, a lens body 3 mounted inside the lens barrel 2, a first protective cover 4 threadedly connected to the outer side of the lens barrel 2, a sliding groove 5 provided inside the first protective cover 4, and a second protective cover 6 slidably connected inside the sliding groove 5. The threaded connection structure facilitates the installation and removal of the first protective cover 4. A threaded hole 15 is provided at the top of the lens barrel 2, and a mounting bracket 16 is mounted on the end of the first protective cover 4 away from the second protective cover 6. The mounting bracket 16 has an internal threaded connection with a bolt 17. One end of the bolt 17 is threaded into a threaded hole 15. By rotating the bolt 17, it can be fixed or separated from the threaded hole 15, facilitating secondary fixation of the lens barrel 2 and the first protective cover 4, which helps improve the stability of the protective structure installation. A support frame 7 is fixedly installed on one side of the second protective cover 6. A support shaft 8 is fixedly connected to the inner side of the support frame 7. A fixing member 9 is sleeved on the outer side of the support shaft 8. A lens cap 10 is fixedly connected to one side of the fixing member 9. The diameter of the lens cap 10 is larger than the diameter of the second protective cover 6. The lens cap 10 and the second protective cover 6 are... The alignment facilitates the protection of the lens barrel 2 and lens body 3. Simultaneously, the rotation of the fixing member 9 allows the lens cap 10 to be directly removed from one end of the second protective cover 6, opening the second protective cover 6 directly and avoiding obstruction of shooting. The fixing member 9 has an internal mounting hole 18, and a rubber anti-slip sleeve 19 is fitted onto the outer side of the support shaft 8. The outer side of the rubber anti-slip sleeve 19 fits snugly against the mounting hole 18, increasing friction in the fixing member 9 and preventing the fixing member 9 and lens cap 10 from rotating or flipping automatically. A telescopic spring 11 is installed inside the sliding groove 5, with one end of the telescopic spring 11 fixedly connected to the second protective cover 6. The deformation of the telescopic spring 11 and the sliding structure of the second protective cover 6 facilitate the buffering of the impact force received by the second protective cover 6, making it less prone to damage. A rubber sealing gasket 12 is installed on the inner side of the lens cover 10, and the rubber sealing gasket 12 is attached to one end of the second protective cover 6. A magnetic metal strip 13 is installed on one end of the second protective cover 6, and a magnet strip 14 is installed on one side of the rubber sealing gasket 12. The magnet strip 14 is attached to the magnetic metal strip 13. The magnetic attraction between the magnetic metal strip 13 and the magnet strip 14 helps to increase the tightness between the lens cover 10 and the second protective cover 6, preventing rainwater from seeping in.

[0023] In summary, this vision-use industrial camera lens protection structure, during use, involves placing the first protective cover 4 over the outside of the lens barrel 2, rotating the first protective cover 4, and fixing it to the lens barrel 2 via a threaded connection. Then, rotating the bolt 17 connected to the internal thread of the mounting bracket 16 on the first protective cover 4 allows one end of the bolt 17 to be inserted into the threaded hole 15 on the lens barrel 2. Similarly, the threaded connection between one end of the bolt 17 and the threaded hole 15 secures it to the lens barrel 2. The lens cap 10 at one end of the first protective cover 4 and the second protective cover 6 covers the lens barrel 2, shielding the lens body 3. Simultaneously, the rubber on the inner side of the lens cap 10... The sealing gasket 12 is attached to one end of the second protective cover 6, and the magnetic strip 14 on one side of the rubber sealing gasket 12 is magnetically attracted to the magnetic metal strip 13 at one end of the second protective cover 6, sealing the second protective cover 6. Since the second protective cover 6 is slidably connected to the sliding groove 5 in the first protective cover 4, and the other end of the second protective cover 6 is fixedly connected to the telescopic spring 11, the first protective cover 4 and the second protective cover 6 protect the lens body 3 and the lens barrel 2 when they are impacted. The second protective cover 6 automatically slides under force by the deformation of the telescopic spring 11, which buffers the force. When shooting is required, the lens cap 10 at one end of the second protective cover 6 is rotated to open the second protective cover 6.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
