Description

Technical Field

[0001] This utility model relates to the field of digital camera accessories, specifically a dustproof pad for digital cameras. Background Technology

[0002] Digital cameras use dustproof gaskets to protect the camera's interior from dust, impurities, and other external substances. The dustproof gaskets are located at the seam between the camera lens and the camera body, and they serve to fill and seal the gap to prevent dust and other tiny particles from entering the camera's interior.

Furthermore, dust adhering to the surface of the gasket is difficult to clean, thus reducing the maintenance efficiency of the dustproof gasket. Therefore, a new dustproof gasket for digital cameras is proposed to address the above problems. Utility Model Content
