Description

Technical Field

[0001] The utility model relates to the technical field of shading sheets, in particular to an ultra-thin precision shading sheet. Background Art

[0002] A shade sheet is a thin sheet or material used to block light. It is commonly used in curtains, blinds, curtain fabrics and some special shading devices. The material of a shade sheet is usually a cloth or plastic sheet with high shading performance, which can effectively block sunlight and external light from entering the room, provide better shading effect, and reduce the light intensity in the room. The use of a shade sheet can help adjust the brightness of the light in the room, provide better privacy protection and a comfortable indoor environment; a lens shade sheet is a device used to block light from entering the lens. It is usually made of metal or plastic and is designed to match a specific lens size. The shading sheet is installed at the front end of the lens to reduce or eliminate optical problems such as halo, light spot and lens reflection that may be caused when light enters the lens. The main function of the shading sheet is to block light from the side or back from entering the lens, reduce light scattering and reflection, and improve the contrast and clarity of the image. It can also effectively reduce direct light from the front end of the lens and avoid lens reflection caused by direct light entering the lens. In addition to blocking light from entering the lens, the shading sheet can also provide additional protection to prevent accidental collision or scratches on the front end of the lens. In addition, the shading sheet can also serve as a mounting base for accessories on the front end of the lens, making it convenient for users to install other filters, lens capsules and other accessories.

[0003] In the prior art, the structure of the shading sheet is relatively simple. In actual use, especially when multiple shading sheets are stacked, the movement difference between the shading sheets is large, which makes it difficult to keep them neat when stacked. At the same time, the shading sheet is also difficult to fix during use, and additional guiding and directional equipment is required to determine its position in advance before it can be fixed, which is rather troublesome. Based on this problem, we propose an ultra-thin precision shading sheet. Utility Model Content

[0007] Preferably, the positioning device comprises two docking holes which are arranged through the side wall of the shading sheet body, and the positions of the two docking holes are arranged along the diagonal line of the shading sheet body.

Different shading sheets can be staggered when stacked, and stable stacking can be achieved by corresponding docking protrusions to the docking holes, which is convenient for positioning. When installing, the position of the shading sheet can be directly located through the corresponding docking holes, which is convenient for positioning and docking. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a structural schematic diagram of an ultra-thin precision light shielding sheet proposed by the utility model;

[0015] Figure 2 The present invention is a schematic diagram of the composition of an ultra-thin precision shading sheet.

[0016] In the figure: 1 shading sheet body, 2 docking hole, 3 docking protrusion, 4 light transmission hole, 5 anti-scratch layer, 6 anti-fouling layer, 7 base layer, 8 anti-reflection layer, 9 glue coating layer. DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2An ultra-thin precision shading sheet comprises two shading sheet bodies 1, each of which is provided with a light-transmitting hole 4 at the center thereof, and each of which is provided with a corresponding positioning device at the side walls thereof. The positioning device comprises two docking holes 2 which are provided on the side walls of the shading sheet body 1, and the positions of the two docking holes 2 are arranged along the diagonal line of the shading sheet body 1.

[0019] Specifically, the side walls of the two shading sheet bodies 1 are fixedly connected with corresponding docking devices, and the docking devices include two docking protrusions 3 fixedly connected to the side walls of the shading sheet body 1. The positions of the two docking protrusions 3 are arranged along another diagonal line of the shading sheet body 1, and the positions of the two docking protrusions 3 correspond to the positions of the corresponding two docking holes 2.

[0020] Among them, the two shading sheet bodies 1 are composed of an anti-scratch layer 5, an anti-fouling layer 6, a base layer 7, an anti-reflection layer 8 and a rubber layer 9. The anti-scratch layer 5 is an anti-scratch coating, and the anti-scratch coating is a diamond-like carbon film. The diamond-like carbon film can improve the wear resistance of the shading sheet body 1. The anti-fouling layer 6 is composed of a hydrophobic material. The anti-reflection layer 8 is a magnesium fluoride vapor-deposited film. A single layer of magnesium fluoride film can be used as an anti-reflection film coated on the surface of optical glass. Since its refractive index is lower than that of optical glass, the incident light has the same phase change when reflected at the upper and lower interfaces of the film, which can reduce the reflection of the incident light at the lens interface and reduce the halo.

[0021] In the utility model, when multiple shading sheet bodies 1 are stacked, the positions of each docking hole 2 and the corresponding docking protrusion 3 can be matched so that adjacent shading sheet bodies 1 can be docked together, thereby increasing the stacking stability of the shading sheet bodies 1. During installation, additional docking protrusions 3 corresponding to the docking holes 2 can also be provided at the installation position to adapt to the positioning connection of the shading sheet body 1.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
