【 Patent abstract 】 An optical lens is glass, and has a first mirror and a second lens, the optical lens in the first on the surface of the mirror's side has a certain level, and a first datum, to a first must have a thing to arrive, and supply to fixed, respectively, the first mirror and the first must have a relative position between axial and radial; The optical lens in the second on the surface of the mirror in the side with a second datum, to a second locator to arrive, and supply with a fixed the second mirror and the axial relative position between the second positioning objects; In addition, the optical lens with a convex walls surrounding the outer peripheral of the optical lens set. 【 Patent description 】 Optical lens' Technology 】 ( 0001] The utility model is related with the optical; Especially refers to a kind of optical lens. 【 Technical background 】 ( 0002] With the progress of science and technology of optical camera, the camera, projector, such as optical devices are increasingly popular, and for the optical device of the optical efficiency has the biggest influence, is the design of optical lens. ( 0003] And an optical lens usually consists of two, one for external, the tube, and another is the internal optical lenses, which will direct effects on the optical lens of optical performance, in addition to the optical lens optical design, the other is the error of the relative position between optical lens, the smaller error is, said the closer to the design of the default state, and the optical lens can be more close to the ideal. ( 0004] Lens assembly, however, is usually outer peripheral pressure on optical lens inside the tube, to achieve the purpose of a fixed structure, and makes the lens after forming, usually on the outer peripheral lenses for grinding or cutting, make the outer peripheral shape of the lens can accord with the interior surface of the tube shape, which not only time-consuming work, and for the convenience of assembly, the inner diameter of the inside the tube, usually peripheral outside diameter is greater than the lenses, and making it easier for the error of the assembly when too much because of this, thus affecting the optical lens optical effect of warehouse. Utility model content [ 0005] For this reason, the purpose of the utility model is used to provide a kind of optical lens, lens assembly, may be truly reliable and the relative position between the fixed lens. ( 0006] Edge to achieve the above purpose, the utility model provided by optical lens is glass, is located in the turning of a first lens and a second lens, its characteristic: the optical lens in the first on the surface of the mirror in the side with the first round mirror set certain plane and a first datum, the locating surface and the first datum to a first must have a thing to arrive, and supply to fixed, respectively, the first mirror and the first must have a relative position between axial and radial; The optical lens in the second on the surface of the mirror in the side with the second round mirror set a second datum, the second datum for a second locator to arrive, and supply with a fixed the second mirror and the axial relative position between the second positioning objects; In addition, the optical lens with a convex walls around the outer peripheral of the optical lens set, and the locating surface and the first datum is located between the first mirror and the convex slope, while the second datum is located between the second mirror with the convex walls. ( 0007] Wherein the first datum are angled with the second benchmark parallel to each other. ( 0008] Wherein the first datum is the first mirror close to the surface. ( 0009] Wherein the optical lens in the first mirror's side surface from the central axis to the direction of the convex walls in order to connect the first lens, the first datum and the locating surface. ( 0010] Wherein the first datum with one Angle, formed between the surface and the Angle is an obtuse Angle. ( 0011] Including the locating surface is a inclined plane. ( 0012] Thus, through the optical lens design, the use of the locating surface, the structure of the first datum and the second datum, then can make the lens assembly when the optical lens, not affected by the lens barrel, and can reliably and precisely fixed the optical lenses and other positioning objects ( Like other lenses or gasket, etc. ) The relative position between the.
