Projection wall covering

Abstract

This utility model discloses a projection wallcovering, relating to the field of wallcoverings. Its key technical features include an inner layer and an outer layer. A first connector is fixedly connected to the side of the inner layer away from the wall, and a second connector is fixedly connected to the side of the outer layer near the inner layer. The second connector is detachably connected to the first connector. The weave density of the inner layer is lower than that of the outer layer. In this utility model, when projection is needed, the outer layer is fixed onto the inner layer. The outer layer has a higher weave density and is flatter, and its surface is coated with a titanium dioxide coating to improve reflectivity, ensuring the optical effect of the outer layer's side away from the wall when reflecting projected light. The inner layer has a lower weave density, and its breathability is improved by the absence of padding yarn. Combined with the breathability of the linen yarn itself, this ensures the intensity of gas exchange between the two sides of the inner layer.

Description

Technical Field

[0001] This utility model relates to the field of wallpaper, and more specifically, to a projection wallpaper. Background Technology

[0002] Wallpaper, as a common interior decoration material, is widely used in homes, hotels, offices and other places due to its rich patterns, diverse colors and convenient construction. In recent years, home projection equipment has gradually become a new choice for people to enjoy large-screen audio-visual experience. Traditional home projectors usually project images directly onto the wall, eliminating the steps and space required for installing a screen and corresponding brackets. However, existing wallpapers need to have good breathability for moisture and mildew prevention, so they have some porous structures. These porous structures make it difficult for the wallpaper itself to meet the optical requirements of being a projection reflective surface. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a projection wall covering.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a projection wall covering, comprising an inner layer and an outer layer, wherein a first connector is fixedly connected to the side of the inner layer away from the wall, and a second connector is fixedly connected to the side of the outer layer close to the inner layer, wherein the second connector and the first connector are detachably connected, and the weaving density of the inner layer is less than that of the outer layer.

[0005] The present invention is further configured such that: the first connector is arranged in a linear array along the vertical direction on the inner layer, and the second connector is distributed at the bottom and top of the outer layer.

[0006] The present invention is further configured such that: the cross-section of the first connector is C-shaped, the cross-section of the second connector is semi-cylindrical, the first connector is embedded in the inner layer, and the second connector is embedded in the first connector.

[0007] The present invention is further configured such that the first connector and the second connector are magnetically connected.

[0008] The present invention is further configured such that the inner layer is woven from flax yarn into a plain weave.

[0009] The present invention is further configured such that the outer layer is coated with a titanium dioxide coating on the side away from the inner layer.

[0010] In summary, this utility model has the following beneficial effects: When projection is required, the outer layer is fixed on the inner layer. The outer layer has a higher weave density and is flatter, and its surface is coated with a titanium dioxide coating to improve reflective brightness, ensuring the optical effect of the outer layer on the side facing away from the wall when reflecting projected light. The inner layer has a lower weave density, and the air permeability of the inner layer is improved by the absence of padding yarn. Combined with the air permeability of the linen yarn itself, the gas exchange intensity on both sides of the inner layer is guaranteed. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A projection wall covering, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an inner layer 1 and an outer layer 2. The inner layer 1 is fixedly connected to a first connector 3 on the side away from the wall, and the outer layer 2 is fixedly connected to a second connector 4 on the side close to the inner layer 1. The second connector 4 is detachably connected to the first connector 3. The weaving density of the inner layer 1 is less than that of the outer layer 2. The inner layer 1 is woven from flax yarn into a plain weave. The outer layer 2 is coated with a titanium dioxide coating on the side away from the inner layer 1.

[0017] Specifically, the inner layer 1 is attached to the wall, and the outer layer 2 is located on the side of the inner layer 1 away from the wall. The outer layer 2 and the inner layer 1 are detachably connected by the first connector 3 and the second connector 4. When projection is required, the outer layer 2 is fixed to the inner layer 1. The outer layer 2 has a higher weave density and is flatter, and its surface is coated with a titanium dioxide coating to improve reflective brightness, ensuring the optical effect of the outer layer 2 when reflecting projected light on the side away from the wall. The inner layer 1 has a lower weave density and improves the breathability of the inner layer 1 by using a missing padding yarn. Combined with the breathability of the linen yarn itself, it ensures the intensity of gas exchange on both sides of the inner layer 1. The plain weave ensures the flatness of the inner layer 1 and avoids excessive unevenness on the surface of the outer layer 2. At the same time, the inner layer 1 and the outer layer 2 are partially connected by the first connector 3 and the second connector 4, which also ensures the breathability of the inner layer 1 when the inner layer 1 and the outer layer 2 are connected.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the first connector 3 is linearly arrayed in the vertical direction on the inner layer 1, and the second connector 4 is distributed at the bottom and top of the outer layer 2. The cross-section of the first connector 3 is C-shaped, and the cross-section of the second connector 4 is semi-cylindrical. The first connector 3 is embedded in the inner layer 1, and the second connector 4 is embedded in the first connector 3. The first connector 3 and the second connector 4 are connected by magnetic force.

[0019] Specifically, two second connectors 4 are located at the top and bottom of the outer layer 2, respectively. The second connectors 4 are magnets, and the two second connectors 4 can attract each other. In addition to cooperating with the first connector 3, the second connectors 4 can also help to accommodate the outer layer 2. The structure of the second connectors 4 embedded in the first connector 3 ensures the contact area between the first connector 3 and the second connectors 4. At the same time, the structure of the first connector 3 embedded in the inner layer 1 reduces the distance between the outer layer 2 and the inner layer 1, and avoids excessive deformation of the outer layer 2 under external force. The composite of the inner layer 1 and the first connector 3 is achieved by first hot-pressing a groove on the inner layer 1, and then bonding the first connector 3 to the inner layer 1. The embedded structure ensures the connection strength between the inner layer 1 and the first connector 3, and the linear array definition of the connectors makes it easy to adjust the position of the outer layer 2 on the inner layer 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
