Description

Technical Field

[0001] This utility model belongs to the field of profile technology, and in particular relates to a five-cavity aluminum alloy mullion profile structure. Background Technology

[0002] Existing thermally insulated aluminum alloy door and window profiles are composed of aluminum alloy profiles on both sides connected by a thermal break strip in the middle. With traditional thermal break strips, a large cavity is formed between the aluminum alloy profile and the thermal break strip. In winter, the aluminum alloy profile located at the higher temperature on the indoor side radiates heat outwards, while the aluminum alloy profile located at the lower temperature on the outdoor side receives it, resulting in heat loss. Simultaneously, air convection occurs within the large cavity formed between the aluminum alloy profile and the thermal break strip, transferring heat from the indoor aluminum alloy profile to the outdoor aluminum alloy profile, causing further heat loss and significantly reducing the thermal insulation performance of the thermally insulated aluminum alloy doors and windows.

[0003] like Figure 1 The image shows a cross-section of an existing five-cavity aluminum alloy profile. Each of the two side profiles has a cavity, while two sets of symmetrical T-shaped thermal break strips divide the central cavity into three parts, reducing air convection and improving insulation and heat preservation. However, gaps still exist between the protruding T-shaped part of the thermal break strip and the opposite thermal break strip, resulting in limited sealing and allowing airflow. Therefore, the insulation and heat preservation performance are still insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a five-cavity aluminum alloy mullion profile structure to solve the problems existing in the background art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A five-cavity aluminum alloy mullion profile structure includes a first profile and a second profile. Two sets of heat insulation strips are provided between the first profile and the second profile. The two sets of heat insulation strips are arranged in a centrally symmetrical manner. The heat insulation strips are respectively connected to the first profile and the second profile. The inner side of the heat insulation strip is provided with a groove. An airbag assembly is provided in the groove. The two sets of heat insulation strips are sealed by abutting against the airbag assembly.

[0007] Furthermore, the airbag assembly includes an air tube, a strip-shaped airbag, and a valve nozzle. The air tube is located within the slot, both ends of the air tube are sealed, the cross-sectional dimensions of the air tube are adapted to the cross-sectional dimensions of the slot, and the air tube is snapped and fixed to the slot.

[0008] Furthermore, one end of the strip-shaped airbag extends into the slot and communicates with the air tube, while the other end of the strip-shaped airbag extends out of the slot.

[0009] Furthermore, the valve nozzle is located on the side of the air tube away from the strip-shaped airbag, and the heat insulation strip has a through hole corresponding to the position of the valve nozzle, through which the valve nozzle extends out of the heat insulation strip.

[0010] Furthermore, the slot is integrated with the heat insulation strip, and the top of the slot has a dovetail-shaped structure.

[0011] Furthermore, the heat insulation strip has trapezoidal heads on both sides, and the first profile and the second profile have trapezoidal grooves corresponding to the positions of the trapezoidal heads. The heat insulation strip is engaged with the first profile and the second profile through the trapezoidal heads and the trapezoidal grooves.

[0012] Furthermore, a valve cap is provided at the end of the valve nozzle.

[0013] The beneficial effects of this utility model are:

[0014] 1) The large cavity between the first and second profiles is divided into three smaller cavities by two sets of airbag components. This effectively reduces gas flow at the thermal insulation strip, minimizing the reduction in thermal insulation performance caused by heat exchange and radiation. At the same time, the five-cavity structure effectively reduces noise and improves sound insulation.

[0015] 2) The fully inflated strip-shaped airbag not only presses against the opposite heat insulation strip, but also presses against the opening of the slot to complete the seal, so that external air will not enter the cavity through the through hole. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 The image shows a cross-section of an existing five-cavity aluminum alloy profile. Each of the two side profiles has a cavity, while two sets of symmetrical T-shaped thermal break strips divide the central cavity into three parts, reducing air convection and improving insulation and heat preservation. However, gaps still exist between the protruding T-shaped thermal break strips and the opposite strips, resulting in limited sealing and allowing airflow. Therefore, the insulation and heat preservation performance are still insufficient.

[0024] See Figures 2-5 This utility model provides a technical solution:

[0025] like Figures 2-5 As shown, a five-cavity aluminum alloy mullion profile structure includes a first profile and a second profile. Two sets of heat insulation strips are provided between the first profile and the second profile. The two sets of heat insulation strips are arranged in a centrally symmetrical manner. The heat insulation strips are respectively connected to the first profile and the second profile. The inner side of the heat insulation strip is provided with a groove. An airbag assembly is provided in the groove. The two sets of heat insulation strips are sealed by abutting against the airbag assembly.

[0026] Through the above technical solution, during the assembly stage, the thermal insulation strip is snapped and fixed to the first and second profiles. At this time, the airbag assembly is not inflated, facilitating its insertion into the slot. After installation, the airbag assembly is inflated, causing the strip-shaped airbag to expand and abut against the adjacent thermal insulation strip to complete the seal. At this point, the two sets of airbag assemblies divide the large cavity between the first and second profiles into three smaller cavities, effectively reducing gas flow at the thermal insulation strip location and minimizing the reduction in insulation performance caused by heat exchange and radiation. Simultaneously, each of the first and second profiles has one cavity, resulting in five cavities in the entire aluminum alloy mullion profile structure, effectively reducing noise and improving sound insulation.

[0027] Meanwhile, the airbag assembly expands and presses against the heat insulation strip, thus ensuring the sealing effect of the small cavity and further improving the heat insulation, sealing and heat preservation effects.

[0028] The specific assembly and usage methods are as follows:

[0029] like Figures 2-4As shown, both ends of the thermal insulation strip are provided with trapezoidal heads, and the first and second profiles are provided with trapezoidal grooves at corresponding positions. The trapezoidal heads of the thermal insulation strip are inserted into the trapezoidal grooves to complete the snap-fit ​​fixation. At this time, the two sets of thermal insulation strips are arranged opposite each other, and the two sets of thermal insulation strips are centrally symmetrical.

[0030] like Figure 2 , 3 As shown in Figure 5, the airbag assembly includes an air tube, a strip-shaped airbag, and a valve. One side of the strip-shaped airbag is connected to the air tube, while both ends of the air tube are sealed. Since the cross-sectional dimensions of the air tube match the cross-sectional dimensions of the slot, the air tube is secured by snapping it into the slot. At this point, the opening connecting the air tube and the valve is aligned with the through hole on the heat insulation strip. Then, one end of the valve is inserted through the through hole into the slot and connected to the air tube. The valve and air tube can be connected by threads, thus completing the installation of the air tube and valve. Simultaneously, the valve also locks the air tube, preventing it from sliding within the slot.

[0031] like Figure 2 As shown, the airbag assembly and heat insulation strip are installed at this time, the strip airbag is not inflated, and the strip airbag is located on the top of the slot.

[0032] like Figure 3 As shown, connecting the valve nozzle to an external air pump allows the strip-shaped airbag to be inflated. The pumped gas passes through the air tube into the strip-shaped airbag, inflating it and causing it to come into contact with the opposite heat insulation strip to complete the seal. After the strip-shaped airbag is fully inflated, the valve cap is screwed on at the valve nozzle to prevent air leakage.

[0033] The fully inflated strip-shaped airbag not only presses against the opposite heat insulation strip, but also seals the opening of the slot, preventing external air from entering the cavity through the through hole.

[0034] The large cavity between the first and second profiles is divided into three smaller cavities by two sets of airbag components. This effectively reduces gas flow at the thermal insulation strip, minimizing heat exchange and radiation-induced reduction in insulation performance. Simultaneously, the five-cavity design effectively reduces noise and improves sound insulation.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
