Abstract
The utility model provides a kind of waterproof camera lens.Compared to the prior art, above-mentioned waterproof camera lens, by the way that pressing ring is arranged, and a support sloping platform is integrally formed on the assembly step of pressing ring, and water proof ring is resisted against on support sloping platform, when assembly, makes to support between sloping platform, lens barrel inner wall and the first eyeglass 3 points of compression water proof rings to completely cut off external moisture entrance, reach water proof and dust proof effect；Simultaneously, because the active force of water proof ring acts on support sloping platform, therefore water proof ring to the reaction force of the first eyeglass not in the radial direction of the first eyeglass, therefore the first eyeglass is without radial forces, optics bias is not influenced, meanwhile, by being arranged water proof ring on pressing ring, water repellent component is independent individual, and waterproof effect is not influenced by components cumulative limit.
Description
Technical field
The utility model relates to lens technology field, in particular to a kind of waterproof camera lens.
Background technique
In recent years, the application field and range of waterproof camera lens are more and more wider, as be applied to outdoor environment in on-vehicle lens,
Monitoring camera, moving camera camera lens etc. have higher requirement to the waterproof performance of camera lens, and also require minimum to camera lens aperture
Change.
The water proof ring of existing waterproof camera lens is typically all to be located between eyeglass and lens barrel, and common use is compressed axially waterproof
The waterproof camera lens of structure, by cooperating compression water proof ring to enter to completely cut off external moisture between the first eyeglass and lens barrel platform, with
Reach water proof and dust proof effect.
Above-mentioned waterproof camera lens, since the water proof ring of this waterproof construction will receive the first eyeglass to its axial direction (along light
Axis direction) active force, this axial force can make water proof ring generate radial deformation, and radial deformation draws the radial space of lens barrel
Greatly, it do camera lens outer diameter must accordingly greatly, can not effectively reduce the outer diameter of camera lens；On the other hand, the tolerance of more eyeglass assemblings is tired
Product causes the bulk gap assembled at water proof ring excessive or too small, and final waterproof performance is deteriorated or lens holding is not in place
And loosen, preferable waterproof effect can not be obtained.
