SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem that above-mentioned exists, provide a waterproof camera lens, the entering that can effectual isolated outside steam, effectual solution camera lens make the space size clearance of the waterproof circle department of equipment too big or undersize because of the tolerance accumulation in many lens assembling process, and then lead to the waterproof effect greatly reduced's of camera lens problem.

The utility model discloses a realize above-mentioned purpose, take following technical scheme to realize:

the utility model provides a waterproof camera lens, includes the lens cone and locates inside battery of lens, clamping ring, packing ring and the waterproof circle of O type of lens cone, the clamping ring is used for fixing the battery of lens, the waterproof circle of O type is used for preventing the steam seepage, the packing ring is used for preventing that the waterproof circle of O type from removing.

Preferably, the lens group includes a first lens, a second lens and a third lens which are sequentially arranged along an optical axis, and there are two pressing rings, wherein one of the two pressing rings is wrapped on the outer sides of the lens barrel and the gasket, and the other pressing ring is disposed in a gap between the third lens and the lens barrel.

Preferably, the gasket is provided with one gasket which is arranged at a gap formed by the lens barrel and the pressing ring, and the O-shaped waterproof ring is provided with two gaskets, wherein one gasket is arranged at the gap formed by the lens barrel, the gasket and the first lens, and the other gasket is arranged at the gap between the lens barrel and the third lens.

Preferably, the O-shaped waterproof ring is made of rubber.

Preferably, the cross section of the O-shaped waterproof ring is O-shaped.

Preferably, the outer diameter of the O-shaped waterproof ring arranged in the gap formed by the lens barrel, the gasket and the first lens is 158mm, the wire diameter is 3mm, and the outer diameter of the O-shaped waterproof ring arranged in the gap between the lens barrel and the third lens is 140mm, and the wire diameter is 2.5 mm.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the O-shaped waterproof ring is arranged at the gap formed by the lens cone, the gasket and the first lens and the gap between the lens cone and the third lens, so that the elastic property of the O-shaped waterproof ring can be effectively utilized to reduce the deformation caused by the acting force; because the tolerance accumulation of many lenses equipment can lead to the space dimension clearance of equipment waterproof ring department too big or undersize, consequently set up O type waterproof ring and just can utilize its self elastic force effect to form sealed effect, guarantee better water-proof effects, and the O type waterproof ring set up the position in the clearance department that lens cone, packing ring and first lens are constituteed, the compression of packing ring, lens cone and lens can compress tightly O type waterproof ring, prevent its removal, in order to reach better water-proof effects.

fig. 2 is an optical system diagram of a waterproof lens according to the present invention.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 2, a waterproof lens includes a lens barrel 10, and a lens group, a pressing ring 12, a gasket 13 and an O-shaped waterproof ring 14 which are disposed inside the lens barrel 10, wherein the pressing ring 12 is used for fixing the lens group, the O-shaped waterproof ring 14 is used for preventing water vapor from leaking, and the gasket 13 is used for preventing the O-shaped waterproof ring from moving.

In the embodiment, the O-shaped waterproof rings are arranged at the gap formed by the lens cone, the gasket and the first lens and the gap between the lens cone and the third lens, so that the deformation caused by the acting force can be effectively reduced by utilizing the elastic performance of the O-shaped waterproof rings; because the tolerance accumulation of the multi-lens assembly can lead to overlarge or undersize space size gaps at the position of the assembled waterproof ring, the O-shaped waterproof ring is arranged, so that the sealing effect can be formed by utilizing the elastic force action of the O-shaped waterproof ring, and the better waterproof effect is ensured.

Optionally, the lens group includes a first lens 111, a second lens 112, and a third lens 113 sequentially arranged along the optical axis, and there are two pressing rings 12, one of which is wrapped around the lens barrel 10 and the washer 13, and the other is disposed at a gap between the third lens 113 and the lens barrel 10. In this embodiment, the lens group includes the first lens 111 having a convex surface S1 and a concave surface S2, the second lens 112 having a convex surface S3 and a convex surface S4, the third lens 113 having a convex surface S5 and a concave surface S6.

Optionally, there is one gasket 13 disposed in the gap formed by the lens barrel 10 and the pressing ring 12, and there are two O-shaped waterproof rings 14, one of which is disposed in the gap formed by the lens barrel, the gasket and the first lens, and the other is disposed in the gap formed between the lens barrel and the third lens.

In the structure, the gasket is arranged at the gap formed by the lens cone and the pressing ring, so that the O-shaped waterproof ring can be prevented from moving, and a better waterproof effect is generated. The O-shaped waterproof ring is arranged in a gap formed by the lens cone, the gasket and the first lens, and the O-shaped waterproof ring can be compressed by the compression of the gasket, the lens cone and the lens to prevent the O-shaped waterproof ring from moving so as to achieve a better waterproof effect.

Optionally, the O-shaped waterproof ring 14 is made of rubber. The O-shaped waterproof ring is made of rubber materials, so that deformation caused by stress of the lens can be reduced, a sealing effect can be formed by the aid of elastic force of the O-shaped waterproof ring, and a good waterproof effect is guaranteed.
