Description

Technical Field

[0001] The utility model belongs to the technical field of lens protection, and in particular relates to a lens dust cover. Background Art

[0002] The lens is one of the essential components of a camera. In order to ensure the clarity of the pictures taken by the camera, a dust cover is usually set on the outside of the lens. When the camera is not in use, the dust cover is put on the outside of the lens to seal and protect against dust. When using the camera, just open the dust cover from the outside of the lens.

[0003] Traditional dust covers have certain drawbacks in actual use. After the dust cover is opened from the outside of the lens, the dust cover is directly exposed to the outside. During this period, the inside of the dust cover itself is easily contaminated with dust or water vapor. Then, after the dust cover is put on the outside of the lens, the dust or water vapor carried by the dust cover is easy to stick to the lens, which is not conducive to the normal use of the lens. Therefore, it is necessary to design a new lens dust cover to solve this problem. Utility Model Content

[0004] The utility model aims to provide a lens dust cover to solve the problem that the inner side of the conventional lens dust cover mentioned in the background art is easily contaminated with dust or water vapor when in use.

[0006] Preferably, the fixing strip is a long arc-shaped structure, and the inclined surface is provided on the top surface of the outer end of the fixing strip.

[0007] Preferably, the rubber strip is arranged on the outer end surface of the fixing strip, and two rubber strips are provided.

[0008] Preferably, the sponge strip is arranged on the outer end surface of the fixing strip and is located directly below the rubber strip.

[0009] Preferably, the rotary cover assembly further comprises a sealing ring, which is arranged on the inner surface of the rotary cover and surrounds the outer side of the inner pad.

[0010] Preferably, the rotary cover assembly further comprises a damping shaft, and the rotary cover is rotatably connected to the front end surface of the cover body via the damping shaft.

[0011] Preferably, a disassembly and assembly component is provided between the cover body and the top plate, and the disassembly and assembly component includes a plug-in plate, a plug-in slot, a card block and a card slot, the plug-in plate is fixed to the top of the cover body and inserted into the inside of the plug-in slot opened inside the top plate, and the card block is symmetrically fixed on both sides of the plug-in plate and inserted into the inside of the card slot opened on the inner wall of the plug-in slot.

[0012] Preferably, the disassembly and assembly component further includes anti-slip sheets, and the anti-slip sheets are symmetrically arranged on both sides of the top plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The designed cover body and screw cap assembly can completely cover the outside of the lens, thereby playing a dust-proof role. When in use, turn the screw cap assembly to unscrew it from the outside of the lens. To close it again, you need to turn the screw cap assembly in the opposite direction. During this process, the cleaning assembly on the top plate will scrape the inner pad surface on the inside of the screw cap assembly, thereby cleaning the dust and other debris on the inner pad to prevent subsequent contamination on the lens. Through the above design, the dust-proof protection effect of the dust cover on the lens is improved, which is beneficial to the normal use of the lens. BRIEF DESCRIPTION OF THE DRAWINGS
