Embodiment 1
[0064] Embodiment 1: The parameters of P1 lens and P2 lens are as follows:
[0065] P1 contact length between the lens and the side of the lens barrel H1 Average interference between lens barrel and P1 lens GY1 Flatness T H1＝0.11 0.002 0.003
[0066] Contact length H2 between the P2 lens and the side of the lens barrel Average interference between lens barrel and P2 lens GY2 H2＝0.17 0.010
[0067] The last lens and the lens barrel are fully sealed and dispensed;
[0068] Water inflow rate between P1 and lens barrel through hole: 0%;
[0069] The water ingress rate between the last lens and the lens barrel: 0%; it can be concluded that the opening end of the lens barrel can be fully sealed by dispensing glue to prevent the last lens and the edge of the lens barrel from entering water; P1 and P2 can solve the problem of P1 and lens Water enters the cylinder through hole.
Embodiment 2
[0070] Embodiment 2: The parameters of P1 lens and P2 lens are as follows:
[0071] P1 contact length between the lens and the side of the lens barrel H1 Average interference between lens barrel and P1 lens GY1 Flatness T H1＝0.11 0.002 0.003
[0072] Contact length H2 between the P2 lens and the side of the lens barrel Average interference between lens barrel and P2 lens GY2 H2＝0.155 0.010
[0073] The last lens and the lens barrel are fully sealed and dispensed;
[0074] Water inflow rate between P1 and lens barrel through hole: 0%;
[0075] The water ingress rate between the last lens and the lens barrel: 0%; it can be concluded that the opening end of the lens barrel can be fully sealed by dispensing glue to prevent the last lens and the edge of the lens barrel from entering water; P1 and P2 can solve the problem of P1 and lens Water enters the cylinder through hole.
Embodiment 3
[0076] Embodiment 3: The parameters of P1 lens and P2 lens are as follows:
[0077] P1 contact length between the lens and the side of the lens barrel H1 Average interference between lens barrel and P1 lens GY1 Flatness T H1＝0.11 0.004 0.003
[0078] Contact length H2 between the P2 lens and the side of the lens barrel Average interference between lens barrel and P2 lens GY2 H2＝0.155 0.010
[0079] The last lens and the lens barrel are fully sealed and dispensed;
[0080] Water inflow rate between P1 and lens barrel through hole: 0%;
[0081] The water ingress rate between the last lens and the lens barrel: 0%; it can be concluded that the opening end of the lens barrel can be fully sealed by dispensing glue to prevent the last lens and the edge of the lens barrel from entering water; P1 and P2 can solve the problem of P1 and lens Water enters the cylinder through hole.

Abstract
The invention discloses a lens structure capable of preventing water from entering. The structure is characterized in that the structure comprises a lens barrel, and a P2 lens and a P1 lens are sequentially installed in the lens barrel from the top to the bottom; the contact length between the P1 lens and the side surface of the lens barrel is H1, the average interference between the lens barrel and the P1 lens is GY1, and the flatness of the positioning surface of the P1 lens is T; the contact length of the P2 lens and the side surface of the lens barrel is H2; the average interference between the lens barrel and the P2 lens is GY2. According to the lens structure, the P1 is attached to the positioning surface at the bottom of the lens barrel and is compacted by the P2, so that high-pressure water seepage during water washing is prevented from entering the lens through a through hole in the P1 surface, and water does not enter the P1 and a through hole in the lens barrel; and by improving the dispensing of the last lens / pressing ring at the opening end of the lens barrel and the lens barrel, water does not enter the edge of the last lens / pressing ring at the opening end of the lens barrel, so that the waterproof effect is achieved.
Description
technical field [0001] The invention relates to the technical field of lenses, and more specifically relates to a lens structure for preventing water ingress. Background technique [0002] In order to meet customers’ increasing requirements for lens appearance, lens production must introduce water washing process and must ensure that no water enters the lens. Water seepage into the lens will not only affect the internal appearance but also greatly reduce the imaging effect. [0003] Therefore, how to provide a lens structure preventing water ingress is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a lens structure for preventing water ingress, which not only has a simple structure and good waterproof effect, but also does not affect the performance of the lens itself. [0005] To achieve the above object, the present invention provides the following technica...
