Description

Technical Field

[0001] The utility model relates to the technical field of hollow glass, in particular to a hollow glass with self-balancing air pressure. Background Art

[0002] Insulating glass is composed of two or more layers of flat glass. High-strength and high-airtightness composite adhesives are used to bond and seal two or more pieces of glass with sealing strips and glass strips on all sides. Dry gas is filled in the middle and desiccant is filled in the frame to ensure the dryness of the air between the glass sheets. Most of the current insulating glass uses aluminum spacers. A hollow frame is made of aluminum alloy and placed between two pieces of glass to play a supporting role. At the same time, molecular sieves are filled in the aluminum spacers as desiccant. The aluminum spacers are provided with through holes to communicate with the gas between the glasses to absorb moisture and keep them dry. However, the aluminum alloy frame is a rigid support and is bonded to the two pieces of glass with composite glue.

[0003] When the air pressure in the environment where insulating glass is used changes greatly, such as a sudden change in temperature, or a train entering a high-altitude area from a plain area, etc., a large pressure difference will be formed between the air pressure inside the insulating glass and the external air pressure. When the air pressure inside the glass is lower than the ambient air pressure outside the glass, the glass will bend inward and deform. Long-term deformation of the glass will cause the bonding with the aluminum spacer to separate, thereby greatly reducing the sealing of the insulating glass, and the sound insulation, waterproof, heat insulation and other properties of the insulating glass will also be greatly reduced. In more serious cases, the glass will shatter at the junction with the aluminum alloy.

[0004] Therefore, it is particularly important to design a kind of insulating glass with self-balancing air pressure to solve the above defects. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model designs a hollow glass with self-balancing air pressure, which aims to solve the technical problem that the hollow glass in the prior art is easily deformed and damaged due to unbalanced air pressure.

[0007] 2) Technical solution

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A kind of air pressure self-balancing hollow glass comprises glass plates, wherein the glass plates are provided with two pieces, a pair of supporting frames are bonded between the glass plates, a ventilation pipe is bonded between the supporting frames, a clamping frame is fixedly connected to the side of the supporting frames close to the ventilation pipe, a side of the clamping frame close to the ventilation pipe is filled with sealant 1, the pair of ventilation pipes are bonded and fixed between the clamping frames by the sealant, and a desiccant is filled on the side of the clamping frames away from the sealant 1.

[0010] By adopting the above technical solution, when the air pressure in the inner cavity of the laminated glass is lower than the external air pressure, the external air can be sucked into the inner cavity of the glass through the ventilation pipe by using the pressure, so as to achieve the effect of air pressure balance. The desiccant can absorb the moisture in the gas entering the inner cavity of the glass, so that the air entering the inner cavity of the glass remains dry, and the appearance of water mist in the inner cavity of the glass due to humid air is avoided.

[0012] As a preferred solution of the utility model, one side of the support frame corresponding to the clamping frame is fixedly connected with a reinforcing rib.

[0013] By adopting the above technical solution, the reinforcing ribs improve the supporting strength of the supporting frame and the clamping frame, enhance the supporting stability of the supporting frame, and avoid deformation of the supporting frame.

[0014] As a preferred solution of the utility model, a breathable partition net is fixedly connected between the clamping frames and on one side close to the ventilation pipe, and a certain distance is maintained between the breathable partition net and the ventilation pipe.

[0015] As a preferred solution of the utility model, an air inlet hole is formed at one end of the ventilation pipe away from the desiccant, and an isolation net is embedded in the interior of the air inlet hole.

[0016] By adopting the above technical solution, the isolation net can isolate dust and debris in the air, improve the purity of the gas, and prevent dust and flying insects from being sucked into the ventilation pipe and causing blockage when the glass cavity takes in air through the air inlet hole.

[0017] As a preferred solution of the utility model, a limiting net is provided on one side of the desiccant away from the ventilation pipe and between the supporting frames.

[0018] 3) Beneficial effects

[0021] Secondly, the isolation net can isolate dust and debris in the air, improve the purity of the gas, and prevent dust and flying insects from being sucked into the ventilation pipe when the air intake hole is intake, causing blockage;

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] The utility model provides a hollow glass with self-balanced air pressure, which aims to solve the technical problem that hollow glass in the prior art is easily deformed and damaged due to unbalanced air pressure;

[0030] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0031] First, see Figure 1-Figure 3 A kind of air pressure self-balancing hollow glass includes a glass plate 1. The glass plate 1 is provided with two pieces. A pair of supporting frames 2 are bonded between the glass plates 1. The supporting frames 2 provide support for the glass plates 1. A sealant 101 is bonded between the supporting frames 2 and the glass plates 1. The supporting frames 2 are bonded and fixed to the glass plates 1 by the sealant 101, thereby improving the sealing between the supporting frames 2 and the glass plates 1.

[0032] Among them, see Figure 2-Figure 3A clamping frame 201 is fixedly connected to one side of the support frame 2 close to the ventilation pipe 3, and the clamping frame 201 clamps and fixes the ventilation pipe 3. A reinforcing rib 202 is fixedly connected to one side of the support frame 2 corresponding to the clamping frame 201. The reinforcing rib 202 improves the supporting strength of the support frame 2 and the clamping frame 201, enhances the supporting stability of the support frame 2, and avoids deformation of the support frame 2. A breathable partition net 203 is fixedly connected between the clamping frames 201 and close to the ventilation pipe 3. The breathable partition net 203 limits and isolates the desiccant 5, and a certain distance is maintained between the breathable partition net 203 and the ventilation pipe 3.

[0033] For further information, see Figure 1-Figure 2 A ventilation pipe 3 is bonded between the support frames 2, and an air inlet 301 is provided at one end of the ventilation pipe 3 away from the desiccant 5. When the air pressure in the glass cavity is lower than the external air pressure, the air inlet 301 draws the external air into the ventilation pipe 3. An isolation net 302 is embedded in the air inlet 301. The isolation net 302 can block dust and debris in the air, improve the purity of the gas, and avoid dust and flying insects being sucked into the ventilation pipe 3 to cause blockage when the air inlet 301 takes in air.

[0034] For further information, see Figure 1-Figure 3 The side of the clamping frame 201 close to the vent pipe 3 is filled with sealant 4, and the clamping frame 201 is bonded and fixed to the vent pipe 3 by the sealant 4, and the sealant 4 improves the sealing between the vent pipe 3 and the clamping frame 201.

[0035] For further information, see Figure 2-Figure 3 A desiccant 5 is filled on one side of the clamping frame 201 away from the sealant 4. When external air enters the glass cavity through the ventilation pipe 3, the desiccant 5 can absorb moisture in the air to keep the air entering the glass cavity dry, thereby preventing the air from being humid and causing water mist to appear in the glass cavity. A limiting net 501 is provided on one side of the desiccant 5 away from the ventilation pipe 3 and between the supporting frames 2. The limiting net 501 can limit and fix the desiccant 5.

[0036] The working process of the utility model is as follows: first, when the air pressure in the inner cavity of the laminated glass is lower than the external air pressure, the pressure can be used to suck the external air into the inner cavity of the glass through the ventilation pipe 3, so as to achieve the effect of air pressure balance. The isolation net 302 can isolate dust and debris in the air, improve the purity of the gas, and avoid dust and flying insects being sucked into the ventilation pipe 3 when the air inlet 301 is intake, causing blockage. After the external air enters the ventilation pipe 3 through the air inlet 301, the desiccant 5 absorbs the moisture in the gas, so that the air entering the inner cavity of the glass remains dry, and the appearance of water mist in the inner cavity of the glass due to the humid air is avoided. The reinforcing ribs 202 can increase the supporting strength of the supporting frame 2 and the clamping frame 201, enhance the supporting stability of the supporting frame 2, and avoid deformation of the supporting frame 2. The entire operation process is simple and convenient. Compared with the existing hollow glass, the utility model can maintain air pressure balance in the inner cavity of the hollow glass through design, avoid deformation and damage, and avoid water mist caused by humid air in the inner cavity of the glass, thereby improving overall practicality.
