Abstract
The utility model provides a large door-lens with high clearness, comprising a prism, a front convex mirror and an imaging mirror which are arranged in a cavity composed of a front mirror housing and a mirror housing. The utility model is characterized in that a circular white liner is arranged between the front convex mirror and the imaging mirror, and the external surface of the imaging mirror is coated with a layer of coating which can raise resolution and brightness. The utility model has the advantages that after a lens is coated by the coating material, the refraction of the lens glass can be changed to cause the high clearness of the lens to be enhanced. The inner wall of the mirror housing uses the white liner, which enhances the strength of a light path in the spreading process, and reduces the spreading loss to make the picture brightness to be strengthened. The part of the mirror housing, arranged on a door opening, is a necking; the opening is smaller. The utility model is suitable for being assembled by the household.
Description
The utility model belongs to peephole (opal), is the improvement to existing peephole version.
Existing peephole can be divided into two classes by size, and small-sized peephole is used for family more, and its defective is must press close to viewport with eye just can see clearly; And existing large-scale peephole external diameter is about φ 60mm), generally can see target about 2～3 meters, but it still exists some shortcoming: as because resolution, brightness is still less, and picture displayed is still clear inadequately, just can see clearly in the time of can only be nearer apart from peephole; Peephole external diameter from front to back is constant, is generally φ 60mm, and door also should be split into φ 60mm by the dress hole on the body like this, and the reaming of opposite house body is excessive, and is also not attractive in appearance.
The purpose of this utility model is in order to solve above-mentioned existing problems, to provide a kind of high definition large-scale peephole.It is big that it has light field brightness.The resolution height, visual angle wide (120 °), the sharpness height can clearly seen situation outdoors clearly several meters away, by characteristics such as the dress hole dimension are little.
In order to achieve the above object, prism is housed, preceding convex lens, imaging mirror in the cavity that mirror shell and mirror shell constituted before the utility model comprised, it is characterized in that between preceding convex lens and imaging mirror, being equipped with a circular white lining, scribble the coating that one deck can improve resolution, brightness at imaging mirror outside surface.
The part that the mirror shell is contained on the body is a necking down, the ratio 1 of the maximum outside diameter of mirror shell in door and the external diameter of necking down: (0.50～0.75).
Coating is formulated by zapon and alkyd paint thinning agent.
Advantage of the present utility model and good effect are: after 1, camera lens adopted the coating coated, the refraction of lens element changed, and the brightness sharpness of camera lens is improved; 2, mirror shell inwall adopts white lining, has improved the intensity in the light path communication process, reduces propagation loss, and picture brightness is strengthened; 3, the part of mirror shell on aperture of door is a necking down, and perforate is less, is suitable for resident family's assembling.
Fig. 1 is a main cut-open view of the present utility model.
(1) preceding mirror shell; (2) prism; (3) preceding convex lens; (4) mirror shell; (5) clamp nut; (6) white lining; (7) imaging mirror; (8) rear end cap; (9) coating.
Referring to Fig. 1, mirror shell (4) adopts white ABS plastic to make, and preceding mirror shell (1) is connected with mirror shell (4) by screw thread, in the cavity that preceding mirror shell (1) and mirror shell (4) constitute prism (2), preceding convex lens (3), imaging mirror (7) is housed.One circular white lining (6) is housed between preceding convex lens (3) and imaging mirror (7).Scribble one deck coating (9) at imaging mirror (7) outside surface.This coating (9) with 1: 18 ratio zapon and alkyd paint mixing diluents after, be applied to the camera lens surface, after one hour, the brightness of camera lens and sharpness can improve.Mirror shell (4) maximum outside diameter is φ 60mm, and the necking section that is contained on the door is φ 38mm, has so both kept the imaging mirror of φ 50mm, far just can see picture clearly apart from several meters, again can be when assembling perforate less.Object lens of the present utility model are introduced light path by two prisms of k9 type glass, are organized into picture through the secondary convex lens, imaging lens by special processing after, brightness is big, the resolution height, the sharpness height can seen situation outdoors clearly several meters away.
Claims (3)
1, the large-scale peephole of a kind of high definition is equipped with prism (2) in the cavity that mirror shell (1) and mirror shell (4) constituted before it was included in, preceding convex lens (3), and imaging mirror (7) is characterized in that
A, a circular white lining (6) is housed between preceding convex lens (3) and imaging mirror (7);
B, scribble one deck at imaging mirror (7) outside surface and can improve resolution, the coating of brightness (9).
2, the large-scale peephole of high definition according to claim 1 is characterized in that the part that mirror shell (4) is contained on the body is a necking down, and the maximum outside diameter part of mirror shell (4) in door is 1 with the ratio of the external diameter of necking down: (0.50～0.75).
3, the large-scale peephole of high definition according to claim 1 and 2 is characterized in that described coating (5) is formulated by zapon and alkyd paint thinning agent.
