Description

Technical Field

[0001] This utility model belongs to the field of optical equipment technology, specifically a detachable waterproof lens front cover assembly. Background Technology

[0002] With the widespread use of optical equipment in various environments, especially outdoor, underwater or humid environments, lens protection is particularly important. Most existing detachable waterproof lens cap assemblies adopt an integrated design, that is, the entire lens cap is tightly connected to the lens housing. Although this design can provide good waterproof performance to a certain extent, it also has the following significant drawbacks.

[0003] Since the lens cap and lens housing are connected as a single unit, disassembly requires removing the entire lens cap from the lens. This is not only complicated but may also require tools, increasing the user's cost and time. Furthermore, existing one-piece lens caps completely block the lens viewfinder after installation, making it impossible to take pictures without removing the lens cap. Therefore, we have proposed a detachable waterproof lens front cap assembly. Summary of the Invention

[0006] Preferably, the first connecting structure and the second connecting structure cooperate with each other so that the cover fits tightly against the base in the installed state, and a seal is formed between the cover and the base to ensure that moisture cannot enter the lens from the gap between the cover and the base.

[0007] Preferably, the first connecting structure is a slot, and the second connecting structure is a buckle that cooperates with the slot. The buckle connection method allows users to quickly install and remove the cover without the need for tools. The cooperation between the buckle and the slot can ensure a firm connection between the cover and the base while maintaining a seal.

[0008] Preferably, at least one of the first connecting structure and the second connecting structure is provided with a magnetic component. The magnetic component can further enhance the connection stability between the cover and the base, ensuring that it will not loosen during use. The magnetic component can help users align the slots and buckles more easily when installing the cover, improving the ease of installation.

[0009] Preferably, a sealing structure is provided between the connecting part of the base and the lens housing. The sealing structure is an O-ring. The connecting part is provided with a sealing ring mounting groove. The O-ring is installed in the sealing ring mounting groove. The O-ring is used to form a seal between the base and the lens housing. The O-ring forms a seal between the base and the lens housing, further preventing moisture from entering the lens from the connection. The design of the sealing ring mounting groove ensures the stable installation of the O-ring and improves the reliability of the seal.

Align the main body of the cover with the front of the lens, ensuring a tight fit. Align the second connecting structure of the cover with the first connecting structure of the base. Secure the cover to the base using the snap-fit ​​and slot engagement. Magnetic components provide auxiliary adsorption force during connection, ensuring a more secure connection between the cover and the base. After the cover and base are connected, the waterproof sealing gasket inside the cover is compressed, further enhancing the sealing performance and ensuring waterproofing. After installation, the lens front cover assembly is in a waterproof protected state, allowing the user to... Normal framing and shooting are possible through the opening in the base and the observation window on the cover. Due to the sealed design between the cover and the base, water cannot enter the lens, even in humid or underwater environments. Users do not need to remove the cover to check the lens's framing. For more detailed inspection or cleaning, users can press the latch to easily remove the cover. To remove the cover, press the latch on the second connecting structure of the cover to release the latch from the first connecting structure of the base, then gently remove the cover. At this point, the cover separates from the base, exposing the front of the lens, allowing for cleaning or inspection. If lens replacement or more in-depth maintenance is needed, users can release the latch between the base and the lens housing. Users can easily install and remove the cover as needed, while simultaneously checking the lens condition through the observation window, greatly improving ease of use and lens protection.
