Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to an installation structure at the junction of a ventilation duct and energy-saving window glass. Background Technology

[0002] Ventilation ducts ensure indoor air exchange, while energy-saving window glass effectively isolates external temperature changes. Together, they create a healthy and comfortable living environment. To achieve optimal overall performance, the junction between the ventilation duct and the energy-saving window glass must be sealed tightly and smoothly installed to ensure that energy efficiency is not affected and that air circulation is smooth and stable.

[0003] Traditional building ventilation structures use independent ventilation ducts and separate windows. While this design can meet basic ventilation needs, it suffers from low ventilation efficiency and complex installation in practical applications. In existing buildings, it is gradually being combined with windows to improve ventilation efficiency and energy saving. However, the current combination method requires opening holes in the windows or installing additional ventilation equipment, which not only increases the difficulty of construction but also affects the aesthetics and airtightness of the windows.

[0004] In response to the aforementioned related technologies, this invention proposes an installation structure at the junction of the ventilation duct and the energy-saving window glass to address the shortcomings of the prior art. Summary of the Invention

[0027] In summary, the present invention has at least one of the following beneficial technical effects:

[0028] 1. This invention uses a rotating screw to pass through a support plate. One end of the screw is connected to a top button. As the screw is screwed in, the pressure relief pleats are gradually compressed until the friction plate and the louver are completely attached and stable, thus completing the adjustment. This structure has a safety redundancy design. When facing a large louver, if vibration occurs, the pressure relief pleats and silicone strip can be kept compressed by the internal negative pressure and the non-reset state of the silicone strip, thereby continuously and stably fixing and achieving self-adaptive clamping.

[0029] 2. This invention achieves efficient sealing and heat insulation through the synergistic effect of multiple coaxially arranged sealing and heat insulation units. The first wear-resistant rubber sealing layer tightly adheres to the pipe during clamping, forming a reliable sealing barrier. The second metal sealing strip, combined with silicone sealant, effectively blocks airflow penetration within the tortuous channel. Finally, the hollow heat insulation strip and the internal vacuum heat insulation cotton work together to block heat transfer, thereby achieving a sealing and heat insulation effect.

[0030] 3. By cooperating with the first rotating shaft on the inner side, this invention effectively reduces the load on the glass while maintaining structural strength. Its inner cavity is equipped with silicone buffer protrusions, which can disperse the impact force to a larger contact surface and enhance the buffering effect. The top of the limiting block is equipped with hydraulic oil. When the limiting block moves upward and approaches the critical position, the hydraulic pressure can cause it to automatically reset, thereby preventing excessive displacement from causing the device to fall off and improving the impact resistance of the connection.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be further described in detail below.

[0041] Please see the appendix Figure 3 - Appendix Figure 4 The installation structure at the junction of the ventilation duct and the energy-saving window glass includes a multi-channel pipe 1, which is part of the ventilation duct and consists of multiple pipes to improve the fluid exchange rate within the duct. The top of the multi-channel pipe 1 is equipped with an adaptive mechanism 3, which is used to adapt to clamping air ducts of different sizes. A window frame 2 is fixedly connected to the outside of the multi-channel pipe 1, which is used to fix the base components. A sealing mechanism 4 is provided on the outside of the window frame 2, which is used to enhance the sealing performance at the junction of the multi-channel pipe 1 and the window frame 2. A limiting mechanism 5 is provided on the outside of the multi-channel pipe 1, which is used to improve the impact resistance at the junction of the multi-channel pipe 1 and the window frame 2.

[0042] The adaptive mechanism 3 includes a strip 301, which is the basic structure of the adaptive mechanism 3. An adjustment groove 311 is provided on the outer side of the strip 301. The adjustment groove 311 works in conjunction with the clamping strip 302 to adjust the tightness of necessary components. The clamping strip 302 is slidably connected to the inner side of the strip 301. A friction plate 303 is fixedly connected to the outer side of the clamping strip 302. The friction plate 303 is used to further improve the tightness of the clamping strip 302 and prevent slippage. Two rail blocks 304 are fixedly connected to the outer side of the clamping strip 302. A fixing arc 305 is fixedly connected to the top of the multi-channel tube 1. The fixing arc 305 works in conjunction with the rail blocks 304 to support the movement of the clamping strip 302. The support enhances the horizontal stability of the clamping strip 302. A pressure relief pleat 306 is fixedly connected to the outer side of the strip 301. The pressure relief pleat 306 has a hollow structure and an air hole at one end. When there is a change in air pressure, the pressure relief pleat 306 will adaptively contract or expand. Compared with springs, its material will not experience fatigue and has a longer service life. The adaptive mechanism 3 also includes multiple silicone strips 307. The silicone strips 307 can be bent with high strength according to actual needs to adapt to the usage scenario of the pressure relief pleat 306. The silicone strips 307 are fixedly connected to the outer side of the pressure relief pleat 306. A top button 308 is fixedly connected to the other side of the silicone strip 307. The top button 308 is used to cooperate with the silicone strip 307.

[0043] Specifically, an adjustment groove 311 is provided on the outer side of the strip 301. The adjustment groove 311 cooperates with the clamping strip 302 to adjust the tightness of necessary components. The inner side of the strip 301 and the clamping strip 302 form a sliding connection. A friction plate 303 is firmly connected to the outer side of the clamping strip 302. The friction plate 303 is used to enhance the clamping effect of the clamping strip 302 and prevent slippage. Two rail blocks 304 are also fixed on the outer side of the clamping strip 302. A fixing arc 305 is installed on the top of the multi-channel pipe 1. The fixing arc 305 works in conjunction with the rail blocks 304 to provide support for the operation of the clamping strip 302, thereby improving... Its stable performance in the horizontal direction is achieved by fixing a pressure relief pleat 306 to the outer side of the strip 301. The pressure relief pleat 306 has a hollow structure inside and an air hole at one end. When the air pressure changes, the pressure relief pleat 306 can adaptively contract or expand. Compared with common springs, it also has a longer service life. The silicone strip 307 can be bent significantly according to the needs of use to adapt to the working conditions of the pressure relief pleat 306. The silicone strip 307 is fixed to the outer side of the pressure relief pleat 306, and a top button 308 is fixed to the other side of the pressure relief pleat 306. The top button 308 and the silicone strip 307 work together to achieve the corresponding functions.

[0044] Please see the appendix Figure 5The sealing mechanism 4 includes wear-resistant rubber 401, which is used to achieve initial sealing and buffering. Wear-resistant rubber 401 is fixedly connected to the outside of the window frame 2. A metal sealing strip 402 is fixedly connected to the outside of the wear-resistant rubber 401. The metal sealing strip 402 can extend the air permeation path. Silicone sealant 403 is fixedly connected to the inside of the metal sealing strip 402. Silicone sealant 403 has good high temperature resistance and anti-aging ability, and can achieve temperature isolation between the internal and external environments to a certain extent, avoiding the impact of temperature on the stable operation of the structure. Two hollow heat insulation strips 404 are fixedly connected to the outside of the metal sealing strip 402. Vacuum heat insulation cotton 405 is fixedly connected to the adjacent side of the two hollow heat insulation strips 404. The hollow heat insulation strips 404 and vacuum heat insulation cotton 405, together with the hollow structure of the energy-saving window, form a further heat insulation effect.

[0045] Specifically, the sealing mechanism 4 uses wear-resistant rubber 401 as the outer edge component, which is connected to the metal sealing strip 402 on the outside. The metal sealing strip 402 can increase the path length of air passage. On the inner side of the metal sealing strip 402, silicone sealant 403 is fixed thereon. The silicone sealant 403 can withstand high temperatures and is resistant to aging, and can effectively block the transfer of temperature between the internal and external environments, thereby reducing the impact of temperature changes on the normal operation of the structure. Two hollow heat insulation strips 404 are set on the outside of the metal sealing strip 402. Vacuum heat insulation cotton 405 is connected between the adjacent surfaces of the two hollow heat insulation strips 404. The hollow heat insulation strips 404 and vacuum heat insulation cotton 405 work together, combined with the cavity structure of the energy-saving window itself, to enhance the overall thermal insulation performance.

[0046] Please see the appendix Figure 6 - Appendix Figure 8The limiting mechanism 5 includes a first bearing 501, which is fixedly connected to the top of the multi-channel pipe 1. A first rotating shaft 502 is fixedly connected to the inner side of the first bearing 501. The first bearing 501 and the first rotating shaft 502 are used to control the rotation of the outer column 503. The outer column 503 is rotatably connected to the outer side of the first rotating shaft 502. A first rotating hole 509 is opened on the outer side of the outer column 503. A hexagonal cavity 507 is opened on the inner side of the outer column 503. The hexagonal cavity 507 is used to reduce the load on the window glass and ensure structural strength. An inner cavity 508 is opened at the top of the outer column 503. The inner cavity 508 is used to set key structures. Multiple buffers are set on the inner side of the inner cavity 508. The bump 511, a buffer bump 511, is made of silicone material, which can disperse concentrated stress to a larger contact area and improve the buffering effect. The inner side of the outer column 503 is slidably connected to the limit block 512. The top of the limit block 512 is provided with hydraulic oil. When the upward displacement of the limit block 512 inside the outer column 503 is about to reach the critical value, the limit block 512 will be moved downward under the action of hydraulic pressure, thereby avoiding excessive displacement and the risk of the device falling off. The top of the limit block 512 is fixedly connected to the inner column 505, which is used to connect the limit block 512. The outer side of the inner column 505 is provided with a second rotating hole 510, which facilitates the rotation of the second rotating shaft 504.

[0047] Specifically, the first bearing seat 501 is installed on the top surface of the multi-channel pipe 1 and is fixedly connected to the inner first rotating shaft 502. The outer column 503 forms a rotational fit with the first rotating shaft 502. A first rotating hole 509 is arranged on its outer side, and a hexagonal cavity 507 is formed on its inner side. The hexagonal cavity 507 can share the weight borne by the window glass while ensuring structural strength. An inner cavity 508 is set at the top of the outer column 503 to accommodate important internal structures. Several silicone buffer protrusions 511 are distributed on the inner wall of the inner cavity 508. The buffer protrusions 511 can absorb the weight of the window glass. Concentrated stress is dispersed over a wider area, thereby improving buffering performance. The inner side of the outer column 503 is slidably connected to the limiting block 512. The top of the limiting block 512 is filled with liquid oil. When the upward movement of the limiting block 512 inside the outer column 503 is about to reach its limit, the hydraulic pressure generated by the liquid oil will cause the limiting block 512 to move downward back, preventing the danger of falling off due to excessive displacement. The top of the limiting block 512 is connected to the inner column 505. A second rotating hole 510 is opened on the outer side of the inner column 505 to provide the necessary space for the rotation of the second rotating shaft 504.

[0048] Please see the appendix Figure 1 - Appendix Figure 3A support plate 310 is fixedly connected to the top of the strip 301. A screw 309 is threaded onto the inner side of the support plate 310. The support plate 310 and the screw 309 cooperate to adjust the moving distance of the clamping strip 302. A second rotating shaft 504 is rotatably connected to the inner side of the inner column 505. A second bearing 513 is fixedly connected to the outer side of the second rotating shaft 504. The second rotating shaft 504 and the second bearing 513 are used to control the rotation of the inner column 505. A fixing plate 506 is fixedly connected to the outer side of the second bearing 513. The fixing plate 506 is used to fix one end of the inner column 505 to the wall to improve the overall stability. An outer glass 6 is fixedly connected to the inner side of the window frame 2. A fireproof glass 6 is fixedly connected to the inner side of the window frame 2. Dust net 7 is used to prevent dust from entering the room during air circulation. The top of the multi-channel pipe 1 is provided with a magnetic suction groove 9. A magnetic suction cover 8 is fixedly connected to the top of the multi-channel pipe 1. The magnetic suction groove 9 and the magnetic suction cover 8 cooperate with each other to isolate the adaptive mechanism 3 from the outside world and prevent it from contacting the external environment and causing corrosion. A fixed frame 10 is fixedly connected to the inside of the multi-channel pipe 1. Multiple blades 11 are rotatably connected to the inside of the fixed frame 10. The fixed frame 10 and the blades 11 together form a louver. The top of the multi-channel pipe 1 is connected to the main air duct 12. The main air duct 12 is used to collect the fluid in the multi-channel pipe 1 in one place. A fixed edge 13 is fixedly connected to the top of the main air duct 12 to fix the main air duct 12 to other structures.

[0049] Specifically, a support plate 310 is installed above the strip 301. The support plate 310 is internally connected to a screw 309 via threads. The two work together to adjust the travel of the clamping strip 302. A second rotating shaft 504 is installed inside the inner column 505. A second bearing seat 513 is fixed to the outside of the second rotating shaft 504. Through the cooperation of the second rotating shaft 504 and the second bearing seat 513, the rotation state of the inner column 505 is controlled. A fixing plate 506 is connected to the outside of the second bearing seat 513. The fixing plate 506 can anchor one end of the inner column 505 to the wall, thereby improving the stability of the entire device. The outer glass 6 is fixed inside the window frame 2, and is also equipped with... A dustproof net 7 is provided, which can intercept dust when the air flows, preventing it from entering the indoor space. The top of the multi-channel pipe 1 is equipped with a magnetic suction groove 9 and a magnetic suction cover 8. The magnetic suction groove 9 and the magnetic suction cover 8 attract each other, so that the adaptive mechanism 3 is isolated from the external environment to reduce the risk of corrosion. The multi-channel pipe 1 is equipped with a fixed frame 10 inside, and several blades 11 are rotatably connected inside the fixed frame 10. The two are combined to form a louver structure. The upper part of the multi-channel pipe 1 is connected to the main air duct 12. The main air duct 12 is used to collect the fluid in the multi-channel pipe 1. The top of the main air duct 12 is equipped with a fixed edge 13, which is used to connect and fix the main air duct 12 to other components.

[0050] Working principle: Initially, the venetian blinds are in a relaxed state with poor stability. By turning screw 309, the screw 309 passes through the support plate 310 through the thread. One end of screw 309 is fixedly connected to a top button 308, and the other side of the top button 308 is fixed to a silicone strip 307. As screw 309 is continuously screwed into the support plate 310, the pressure relief pleats 306 are gradually compressed, causing the track block 304 to drive the clamping strip 302 to move horizontally in the adjusting groove 311. When the friction plate 303 is completely in contact with the venetian blinds and... After stabilizing, stop rotating screw 309 to complete the adjustment. There is a safety redundancy in the structure, which is the design of pressure relief pleats 306 and silicone strips 307. When dealing with large venetian blinds, if the venetian blinds vibrate due to an accident after fixing, it will not affect the overall stability. This is because there is negative pressure inside pressure relief pleats 306. As long as silicone strips 307 are not in the reset state, pressure relief pleats 306 can always be in a compressed state to maintain the fixation of the venetian blinds, thus achieving an adaptive clamping effect.

[0051] Furthermore, relying on the stable assembly benchmark provided by the adaptive mechanism 3, sealing and heat insulation are achieved through three coaxially arranged sealing and heat insulation units. The first layer of wear-resistant rubber 401 seals adheres to the ventilation pipe as the jacket clamps, forming an initial sealing barrier. The second layer of metal sealing strip 402 extends the air permeation path using a tortuous channel, and further blocks airflow with silicone sealant 403. The third layer of hollow heat insulation strip 404 echoes the hollow structure of the energy-saving window, and blocks heat transfer through vacuum heat insulation cotton 405, achieving the parallel function of sealing and heat insulation.

[0052] Finally, the first bearing seat 501 is fixed to the top of the multi-channel pipe 1, and the first rotating shaft 502 is fixed to its inner side. The two work together to control the rotation of the outer column 503. The outer column 503 rotates through the first rotating shaft 502. The outer side is provided with a first rotating hole 509, and the inner side is provided with a hexagonal cavity 507. The hexagonal cavity 507 reduces the load on the window glass while maintaining the structural strength. The inner cavity 508 is equipped with silicone buffer protrusions 511, which enhance the buffering performance by dispersing the concentrated stress to a larger contact surface. The inner side of the outer column 503 is slidably connected to the limiting block 512. The top of the limiting block 512 is provided with hydraulic oil. When the limiting block 512 moves upward and approaches the critical value, it is hydraulically driven to reset downward, avoiding excessive displacement that could cause the device to fall off. This achieves the absorption and utilization of impact energy and improves the impact resistance reliability of the structure at the junction.
