Technical Field

[0001] This utility model relates to the field of coated glass technology, specifically to a multi-layer coated glass for heat insulation. Background Technology

With the development of technology, the number of buildings and high-rises is constantly increasing, and glass is an indispensable component of these buildings.

[0003] The existing authorization announcement number CN212833493U3 discloses a multi-layer coated glass for heat insulation, including an inner layer and a middle plate.

The middle plate has a groove inside, and a locking groove is provided at the bottom of the lifting groove. An outer plate is fixedly installed on one side of the connecting rod.

A limiting groove is provided at the middle end of the side plate, and a sliding rod is provided in the inner circle of the limiting groove. A spring is wound on the sliding rod.

[0004] While the above-mentioned device can easily achieve the effects of heat insulation and heat preservation while simplifying the installation process, in the current design of double or multi-layer glass, if a certain amount of inert gas can be filled in the middle gas layer, the heat conduction through the glass can be effectively reduced due to the low thermal conductivity of the inert gas, thereby achieving the purpose of heat insulation and heat preservation. Therefore, we propose a multi-layer coated glass for heat insulation and heat preservation. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer coated glass for heat insulation, in order to solve the problem mentioned in the background art that if a certain amount of inert gas is filled in the middle gas layer of double or multi-layer glass, the heat conduction through the glass can be effectively reduced due to the low thermal conductivity of the inert gas, thereby achieving the purpose of heat insulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating multi-layer coated glass, comprising a frame, a placement groove at the upper end of the frame, an intermediate glass fixedly connected to the inner wall of the placement groove, an intermediate air layer formed on the inner wall of the intermediate glass, an electric telescopic rod fixedly connected to the bottom end of the inner wall of the intermediate air layer, and a connecting plate fixedly connected to the end of the electric telescopic rod away from the intermediate air layer.

[0007] As a further preferred embodiment of this technical solution, the inner wall of the intermediate glass is provided with an isolation plate, the bottom end of the inner wall of the isolation plate is provided with an isolation groove, and the bottom end of the inner wall of the isolation groove is fixedly connected with a heat-insulating baffle.

[0008] As a further preferred embodiment of this technical solution, a sealing plate is fixedly connected to the surface of the intermediate glass. The number of sealing plates is set to two, and the two sealing plates are symmetrically arranged about the center of the intermediate glass. A heat insulation layer is fixedly connected to the upper end of the sealing plate, and polyurethane adhesive is bonded to the connection between the sealing plate and the mating plate.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the heat insulation layer is provided with vacuum grooves, and the number of vacuum grooves is set to several, all of which are opened inside the heat insulation layer. The end of the heat insulation layer away from the middle glass is fixedly connected to the inner glass.

The number of heat insulation layers is set to two, and the two heat insulation layers are symmetrically arranged about the center of the middle glass.

[0013] This utility model provides a multi-layer coated glass for heat insulation and preservation, which has the following beneficial effects:

[0014] (1) This utility model provides an intermediate gas layer on the inner wall of the intermediate glass, which is filled with argon gas. Since argon gas has a low thermal conductivity, which is lower than that of air, it can effectively reduce the heat conduction through the glass, thereby achieving the heat preservation effect of multi-layer coated glass. At the same time, since the heat insulation layer has several vacuum grooves inside, and a certain amount of inert gas is also provided inside the vacuum grooves, it is filled between the glass layers by vacuum sealing to form a heat insulation layer. This gas filling can effectively reduce heat convection and heat conduction, thereby improving the heat insulation performance of the window.

[0015] (2) This utility model has a low-emissivity coating and a reflective film fixedly connected to the upper end of the inner glass, which can effectively reflect infrared rays and reduce heat conduction from the glass to the outside, thereby improving the heat insulation performance of the glass. Furthermore, since a metal oxide coating is fixedly connected to the surface of the outer glass, it can effectively reflect infrared rays and ultraviolet rays, reducing the entry of solar radiation heat. This helps with heat preservation in winter and heat insulation in summer. At the same time, the ultraviolet blocking film is coated with materials such as titanium dioxide or silicon dioxide to absorb or reflect ultraviolet rays, thereby preventing ultraviolet rays from fading the items inside the building and minimizing the damage to human skin.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a heat-insulating multi-layer coated glass includes a frame 1. The upper end of the frame 1 has a placement groove, and an intermediate glass 4 is fixedly connected to the inner wall of the placement groove. An intermediate gas layer 17 is formed on the inner wall of the intermediate glass 4. Since the intermediate gas layer 17 is filled with argon gas, and argon gas has a low thermal conductivity (lower than that of air), it can effectively reduce heat conduction through the glass, thereby achieving the heat insulation effect of the multi-layer coated glass. An electric telescopic rod 15 is fixedly connected to the bottom of the inner wall of the intermediate gas layer 17. A docking plate 16 is fixedly connected to the end of the electric telescopic rod 15 away from the intermediate gas layer 17. With this configuration, when it is necessary to change the thickness of the multi-layer coated glass, the intermediate glass 4 is adjustable. The user only needs to activate the electric telescopic rod 15, which will drive the docking plate 16 at its upper end to move upward, thereby completing the adjustment of the intermediate glass 4 and thus completing the thickness adjustment of the multi-layer coated glass, thereby improving its applicability.

[0023] The inner wall of the middle glass 4 is provided with an isolation plate, and the bottom of the inner wall of the isolation plate is provided with an isolation groove 12. The bottom of the inner wall of the isolation groove 12 is fixedly connected with a heat-insulating baffle 13.

[0024] A sealing plate 14 is fixedly connected to the surface of the middle glass 4. There are two sealing plates 14, which are symmetrically arranged about the center of the middle glass 4. A heat insulation layer 6 is fixedly connected to the upper end of the sealing plate 14. Polyurethane adhesive 3 is bonded to the connection between the sealing plate 14 and the mating plate 16.

[0025] The inner wall of the thermal insulation layer 6 is provided with vacuum grooves 18. Since the thermal insulation layer 6 has several vacuum grooves 18, a certain amount of inert gas is also provided inside the vacuum grooves. By filling the gaps between the glass layers through vacuum sealing, a thermal insulation layer is formed. The filling of this gas can effectively reduce heat convection and heat conduction, thereby improving the thermal insulation performance of the window. The number of vacuum grooves 18 is set to several, and all the vacuum grooves 18 are opened inside the thermal insulation layer 6. The end of the thermal insulation layer 6 away from the middle glass 4 is fixedly connected to the inner glass 2.

[0026] A reflective film 8 is fixedly connected to the upper end of the inner glass 2. A low-emissivity coating 7 is fixedly connected to the end of the reflective film 8 away from the inner glass 2. Two heat insulation layers 6 are set, and the two heat insulation layers 6 are symmetrically arranged about the center of the middle glass 4. Since the low-emissivity coating 7 and the reflective film 8 are fixedly connected to the upper end of the inner glass 2, infrared rays can be effectively reflected, reducing heat conduction from the glass to the outside, thereby improving the heat insulation performance of the glass.

[0027] The thermal insulation layer 6 is fixedly connected to an outer glass 5 at the end furthest from the middle glass 4. An ultraviolet blocking film 9 is fixedly connected to the surface of the outer glass 5. A metal oxide coating 10 is fixedly connected to the end of the ultraviolet blocking film 9 furthest from the outer glass 5. Because the metal oxide coating 10 is fixedly connected to the surface of the outer glass 5, it can effectively reflect infrared and ultraviolet rays, reducing the entry of solar radiation heat. This helps with heat preservation in winter and heat insulation in summer. At the same time, the ultraviolet blocking film 9 is coated with materials such as titanium dioxide or silicon dioxide to absorb or reflect ultraviolet rays, thereby preventing ultraviolet rays from fading the items inside the building and minimizing the damage to human skin.

[0028] A protective pad 11 is fixedly connected to the bottom of the inner wall of the placement groove. A middle glass 4 is fixedly connected to the end of the protective pad 11 away from the placement groove. Polyurethane adhesive 3 is bonded to the connection between the middle glass 4 and the two heat insulation layers 6.

[0029] This utility model provides a multi-layer coated glass for heat insulation, and its specific working principle is as follows:

[0030] This multi-layer coated glass features a placement groove inside the frame 1, with an intermediate glass 4 fixedly connected inside the groove. The inner wall of the intermediate glass 4 has an intermediate gas layer 17 filled with argon gas. Argon gas has a low thermal conductivity, lower than air, effectively reducing heat conduction through the glass, thus achieving the heat insulation effect of the multi-layer coated glass. Simultaneously, a heat insulation layer 6 is fixedly connected to the upper end of the intermediate glass 4. This heat insulation layer 6 has several vacuum grooves 18 inside, each containing a certain amount of inert gas. By filling the spaces between the glass layers through a vacuum seal, this gas forms a heat insulation layer. The filling effectively reduces heat convection and heat conduction, thereby improving the window's thermal insulation performance. Simultaneously, the low-emissivity coating 7 and reflective film 8 are fixedly connected to the upper end of the inner glass 2, effectively reflecting infrared rays and reducing heat conduction from the glass outwards, thus improving the glass's thermal insulation performance. Furthermore, the metal oxide coating 10 is fixedly connected to the surface of the outer glass 5, effectively reflecting infrared and ultraviolet rays and reducing the entry of solar radiation heat. This contributes to thermal insulation in winter and heat insulation in summer. Meanwhile, the ultraviolet blocking film 9 is coated with materials such as titanium dioxide or silicon dioxide to absorb or reflect ultraviolet rays, thereby preventing fading of interior items and minimizing harm to human skin.
