Description

Technical Field

[0001] The utility model relates to the field of waterproof lenses, in particular to a waterproof lens. Background Art

[0002] Waterproof lenses have strong resistance to temperature changes in the operating environment and are more suitable for harsh environmental conditions (such as polar regions and severe weather), and have unparalleled advantages when used in harsh outdoor conditions.

[0003] For example, a waterproof and fog-proof lens in the prior art includes a lens barrel, a lens group, a plano-convex lens, a first sealing ring, and a second sealing ring. The lens barrel includes a receiving seat, the first sealing ring is disposed between the lens group and the receiving seat, the plano-convex lens abuts against the lens group and forms a cavity therebetween, and the second sealing ring is disposed between the lens group and the plano-convex lens and seals the cavity. The lens barrel of the utility model supports the lens group and the plano-convex lens through the receiving seat, and the first sealing ring is placed between the lens barrel and the lens group to isolate the lens from the external environment, thereby achieving external waterproofing of the lens; the second sealing ring is added between the lens group and the plano-convex lens, so that the cavity between the lens group and the plano-convex lens becomes a sealed space. When the lens is in a high temperature and high humidity environment, because the lens basically does not absorb water, the moisture content in the sealed cavity is low, which can effectively slow down the generation of condensation and maintain good imaging quality.

[0004] However, after the lens has been used for a long time, when the absorbent cotton needs to be replaced, the user needs to first disassemble the front cover and then remove the second lens before the absorbent cotton can be replaced. After the replacement is completed, the glue seal needs to be re-applied, which is a cumbersome operation.

[0005] Therefore, it is necessary to provide a waterproof lens to solve the above technical problems. Utility Model Content
