Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of insulated glass, specifically, it relates to an automatic pressure regulating mechanism for insulated glass products. Background Technology
[0002] Insulating glass is a type of glass product consisting of two or more panes of glass bonded together with a high-strength, airtight composite adhesive, creating a dry gas space between the glass layers. This type of glass offers excellent heat and sound insulation, and can reduce the weight of buildings, making it a novel building material. Because the air pressure within the inner space of an insulating glass unit is determined during manufacturing, changes in external temperature, climate, and air pressure during use can cause stress variations, resulting in concave or convex shapes. Existing insulating glass units typically have sealant applied to the outside of the spacer bars, flush with the edge of the glass body, as shown in the attached image. Figure 4 As shown, the structure of the insulated glass is fixed, and the air pressure inside the insulated glass cannot be adjusted.
[0003] In view of this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic pressure regulating mechanism for insulating glass products. To solve the above technical problem, the basic concept of the technical solution adopted by this utility model is as follows:
[0005] An automatic pressure regulating mechanism for insulated glass products includes an insulated glass body, an insulating layer, and a spacer aluminum strip. The insulated glass body includes a first glass layer and a second glass layer. A spacer aluminum strip is provided between the first glass layer and the second glass layer. The spacer aluminum strip is located at the edge of the first glass layer and the second glass layer. A first sealant layer is provided on the outside of the spacer aluminum strip. A buffer self-regulating pressure cavity is provided on the outside of the first sealant layer. A second sealant layer is provided on the outside of the buffer self-regulating pressure cavity. A pressure regulating tube is provided through the spacer aluminum strip. One end of the pressure regulating tube located inside the insulating layer is provided with a limiting end. A sealing plug is provided at the other end of the pressure regulating tube. A groove is provided on the end face of the sealing end of the sealing plug. The sealing plug is used to seal the pressure regulating tube.
[0006] As a further embodiment of this utility model: the settling tank has an internal hexagonal structure, and when the sealing plug is in conjunction with the pressure regulating pipe, the end face of the sealing end is flush with the end faces of the first glass layer and the second glass layer, so that the position of the sealing end can be seen intuitively.
[0007] As a further improvement of this utility model: the pressure regulating tube has a hollow structure inside, and one end of the pressure regulating tube that mates with the sealing plug is provided with an internal thread. The internal thread and the hollow structure form a positioning step. A sealing ring is provided at the mating position of the sealing plug and the pressure regulating tube to ensure the sealing performance of the mating between the sealing plug and the pressure regulating tube.
[0008] As a further improvement of this utility model: the cross-section of the spacer aluminum strip is a trapezoidal hollow structure, the cavity of the spacer aluminum strip is filled with a desiccant, and the spacer aluminum strip has vent holes on the plane located in the inner cavity of the hollow layer to ensure that the gas in the hollow layer is in a dry state.
[0009] As a further improvement of this utility model: the first sealant layer is made of polyisobutylene adhesive, and the second sealant layer is made of silicone adhesive. Polyisobutylene adhesive has good elasticity and weather resistance, which provides a guarantee for the pressure regulation and buffering of the buffer self-regulating cavity. Silicone adhesive has excellent high and low temperature resistance, weather resistance and UV aging resistance.
[0010] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.
[0011] The insulating glass body of this invention has a buffer self-regulating cavity on the outside of the spacer aluminum strip. When the external environment changes, it can act as a buffer cavity for deformation of the insulating glass body, and can buffer and regulate the air pressure in the insulating layer within a small range.
[0012] The insulating glass body of this utility model has a pressure regulating pipe connected to the insulating layer at the sealing point. The end of the pressure regulating pipe is provided with a sealing end. Under normal use, the pressure regulating pipe is sealed by the sealing end to maintain the sealing state of the insulating layer. When the environment in which the insulating glass body is used changes and air pressure needs to be adjusted, the air pressure can be adjusted by opening the sealing end.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0022] like Figures 1 to 4 As shown, the automatic pressure regulating mechanism of the insulating glass product includes an insulating glass body 1, an insulating layer 7, and a spacer aluminum strip 2. The insulating glass body 1 includes a first glass layer 5 and a second glass layer 6. A spacer aluminum strip 2 is provided between the first glass layer 5 and the second glass layer 6. The spacer aluminum strip 2 is located at the edge of the first glass layer 5 and the second glass layer 6. A first sealant layer 9 is provided on the outside of the spacer aluminum strip 2. A buffer self-regulating pressure cavity 4 is provided on the outside of the first sealant layer 9. A second sealant layer 10 is provided on the outside of the buffer self-regulating pressure cavity 4. A pressure regulating pipe 11 is provided through the spacer aluminum strip 2. One end of the pressure regulating pipe 11 located inside the insulating layer 7 is provided with a limiting end 12. The other end of the pressure regulating pipe 11 is provided with a sealing plug 13. A groove 15 is provided on the end face of the sealing end 14 of the sealing plug 13. The sealing plug 13 is used to seal the pressure regulating pipe 11.
[0023] Among them, the settling tank 15 has an internal hexagonal structure. When the sealing plug 13 is in the matching state with the pressure regulating pipe 11, the end face of the sealing end 14 is flush with the end faces of the first glass layer 5 and the second glass layer 6. The position of the sealing end 14 can be seen directly, which does not affect the assembly with the frame structure.
[0024] The pressure regulating pipe 11 has a hollow internal structure. The end of the pressure regulating pipe 11 that mates with the sealing plug 13 is provided with an internal thread. The internal thread and the hollow structure form a positioning step. A sealing ring 16 is provided at the mating position of the sealing plug 13 and the pressure regulating pipe 11 to ensure the sealing performance of the mating between the sealing plug 13 and the pressure regulating pipe 11.
[0025] The spacer aluminum strip 2 has a trapezoidal hollow structure in cross section. The cavity of the spacer aluminum strip 2 is filled with desiccant 8. The spacer aluminum strip 2 has vent holes 3 on its plane in the inner cavity of the hollow layer 7 to ensure that the gas in the hollow layer 7 is in a dry state.
[0026] The first sealant layer 9 is made of polyisobutylene adhesive, and the second sealant layer 10 is made of silicone adhesive. Polyisobutylene adhesive has good elasticity and weather resistance, which provides a guarantee for the pressure regulation and buffering of the self-regulating pressure cavity 4. Silicone adhesive has excellent high and low temperature resistance, weather resistance and UV aging resistance.
[0027] The working principle of this utility model is as follows: During the production of insulated glass products, the air pressure of the inner space is determined during the manufacturing process according to the customer's order requirements. Under normal use, the pressure regulating pipe 11 is in a sealed state. The sealing plug 13 and the sealing ring 16 provide a basic seal for the pressure regulating pipe 11. The sealing adhesive layer 2 10 provides a secondary seal for the cooperation between the pressure regulating pipe 11 and the sealing plug 13, ensuring that the hollow layer 7 inside the insulated glass body 1 is in a sealed state.
[0028] During normal use, if the air pressure inside the insulating layer 7 changes, due to the connectors or frame structure set at the edge of the insulating glass body 1, there will be a certain difference between the air pressure change inside the insulating layer 7 and the air pressure change inside the buffer self-regulating cavity 4. By utilizing the difference in air pressure in the two cavities, a self-regulating buffer can be formed to balance the air pressure. Since the sealant layer 9 is made of polyisobutylene, which has good elasticity and weather resistance, it provides a guarantee for the pressure regulation and buffering of the buffer self-regulating cavity 4.
[0029] In addition, if the usage of the insulating glass body 1 changes, or the altitude of the usage location changes, and it is necessary to adjust the air pressure inside the insulating glass body 1, first, locate the position of the sealing plug 13, use a sharp tool to peel off the second sealing layer 10 in the groove 15 and the second sealing layer 10 around the sealing plug 13, and use an Allen wrench to turn the sealing plug 13 to open the pressure regulating pipe 11. With the help of a dedicated pressure regulating device, the air pressure of the insulating layer 7 can be adjusted and set. There is no need to rework everything, which effectively saves costs and improves the applicability of the insulating glass body 1.
[0030] The insulating glass body 1 of this invention has a buffer self-regulating pressure cavity 4 on the outside of the spacer aluminum strip 2. When the external environment changes, it can act as a deformation buffer cavity for the insulating glass body 1, and can buffer and regulate the air pressure in the insulating layer 7 within a small range. A pressure regulating pipe 11 is provided at the sealing point of the insulating glass body 1 and connected to the insulating layer 7. A sealing end 14 is provided at the end of the pressure regulating pipe 11. Under normal use, the pressure regulating pipe 11 is sealed by the sealing end 14 to maintain the sealing state of the insulating layer 7. When the environment of the insulating glass body 1 changes and air pressure needs to be regulated, the air pressure can be regulated by opening the sealing end 14.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
