Description

Technical Field

[0001] This application relates to the technical field of aluminum alloy profiles, and specifically discloses a complex-section aluminum alloy extrusion profile with heat insulation function. Background Art

[0002] In recent years, with the national industrial policies, the adjustment of industrial structure, and the improvement of consumers' requirements for product quality, the current situation of the extensive and low-value-added aluminum processing industry has gradually changed. It has crossed the primary development stage characterized by quantity growth and has entered a new stage of improving the internal quality of products, enriching product varieties, and participating in market competition relying on comprehensive strength. As the industry develops into a new stage, the intensity of internal integration in the future will continue to increase;

[0003] Regarding broken bridge aluminum, its essence is to cut between two profiles and then use a heat insulation strip to achieve connection. Since the heat insulation strip is not metal, it can block heat transfer;

[0004] However, the current problem is that the distance between the profiles is very close. Even though a heat insulation strip is used to block heat transfer, heat can still be radiated to the other profile with a lower temperature by thermal radiation. The heat insulation strip is not metal and only blocks heat transfer. When the heat is extremely high, the heat insulation effect is not good. In view of this, the inventor proposes a complex-section aluminum alloy extrusion profile with heat insulation function. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of poor heat insulation effect of traditional broken bridge aluminum profiles.

[0006] To achieve the above purpose, this utility model provides the following basic solution:

[0007] A complex-section aluminum alloy extrusion profile with heat insulation function, including a first profile arranged outdoors, a second profile arranged indoors, a cavity body opened inside the second profile and the first profile, a third profile and a fourth profile arranged based on the first profile and the second profile, and a heat preservation cavity arranged inside the third profile and the fourth profile;

[0008] The first profile, the second profile, the third profile and the fourth profile are combined to form a heat insulation installation point, and a number of heat insulation blocks are installed on the heat insulation installation point;

[0009] A number of installation grooves are opened between the first profile and the second profile, and a heat insulation strip for connecting the first profile and the second profile is installed in the installation grooves;

[0010] Partition points for partitioning the first profile, the second profile, the third profile and the fourth profile are provided on the first profile, the second profile, the third profile and the fourth profile, and heat insulation connection blocks are installed on the partition points.

[0011] The principle and effect of this basic solution are as follows:

[0012] 1. Compared with the prior art, the structure of this device is simple and ingenious. This device has the structure of traditional broken bridge aluminum, and uses heat insulation strips to block heat transfer, that is, uses heat insulation strips to isolate the first profile and the second profile, so that the temperatures between the first profile and the second profile do not transfer to each other. However, due to the too small gap between traditional profiles, there is heat radiation. Therefore, this profile is provided with a broken bridge cavity, and the broken bridge cavity is used to isolate the first profile and the second profile again, so that the first profile and the second profile are preferentially isolated from heat conduction. And a relatively large cavity is provided inside the first profile and the second profile, and the cavity is used to increase the gap and reduce the heat brought by heat radiation, thereby improving the heat insulation effect, and finally solving the problem of poor heat insulation effect of traditional broken bridge aluminum profiles.

[0013] 2. Compared with the prior art, based on the first profile and the second profile, this device is provided with a third profile and a fourth profile, and a heat preservation cavity is provided inside the third profile and the fourth profile. The heat preservation cavity is used in cooperation with the cavity to reduce the heat transfer brought by heat radiation and achieve heat isolation.

[0014] 3. Compared with the prior art, as is well known, broken bridge aluminum is mainly used in doors and windows. In order to strengthen the heat insulation effect of doors and windows, most doors and windows use multi-cavity and multi-board doors and windows to achieve heat isolation. In this case, not only multi-cavity and multi-board doors and windows are used, but also improvements are made at the connection points between the multi-cavity and multi-board doors and windows and the broken bridge aluminum structure. Due to the provision of the third profile and the fourth profile, based on the third profile, the fourth profile, the first profile and the second profile, a relatively large installation position is reserved, and a plurality of heat insulation installation points are provided at this installation position. The multi-cavity and multi-board doors and windows are installed by using the heat insulation installation points, so that the temperatures outside and inside cannot be transferred to the multi-cavity and multi-board doors and windows through the first profile, the second profile, the third profile and the fourth profile, thereby achieving temperature isolation, improving the heat insulation effect, and finally solving the problem of poor heat insulation effect of traditional broken bridge aluminum profiles.

[0015] Further, the heat insulation block, the heat insulation connection block and the heat insulation strip are made of the same material.

[0016] Further, the heat insulation block, the heat insulation connection block and the heat insulation strip are all made of PA66 material.

[0017] Further, the groove end faces of the installation grooves are all tapered grooves, and both ends of the heat insulation strip are cones whose shapes are adapted to the tapered grooves.

[0018] Further, a first connection block is provided on the end faces of the first profile and the second profile close to the third profile and the fourth profile, and a second connection block is provided on the end faces of the third profile and the fourth profile close to the first profile and the second profile. The heat insulation installation points are fixed through the first connection block and the second connection block.

[0019] Further, the partition point divides the first profile, the second profile, the third profile and the fourth profile into two parts, and the heat insulation connection block adopts a multi-point co-body structure.

[0020] Further, the multi-point co-body structure includes a main body and protrusions provided on the upper end face and the lower end face of the main body. Slots corresponding to the protrusions in number and position are formed at the positions of the first profile, the second profile, the third profile and the fourth profile where the multi-point co-body structure is located, and the protrusions are clamped with the slots.

[0025] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0026] The reference numerals in the drawings of the specification include: door and window frame 1, door and window 2, partition point 3, first profile 4, third profile 5, heat insulation cavity 6, installation groove 7, heat insulation strip 8, second profile 9, fourth profile 10, heat insulation connection block 11, slot 12, main body 13.

[0027] Embodiments are as followsFigure 1 , Figure 2 and Figure 3 as shown in:

[0028] A complex-section aluminum alloy extrusion profile with heat insulation function, including a first profile 4 arranged outdoors, a second profile 9 arranged indoors, a cavity body opened inside the second profile 9 and the first profile 4, a third profile 5 and a fourth profile 10 arranged based on the first profile 4 and the second profile 9, and a heat insulation cavity 6 arranged inside the third profile 5 and the fourth profile 10;

[0029] The first profile 4, the second profile 9, the third profile 5 and the fourth profile 10 are combined to form heat insulation installation points, and a number of heat insulation blocks are installed on the heat insulation installation points;

[0030] A number of installation grooves 7 are opened between the first profile 4 and the second profile 9, and heat insulation strips 8 for connecting the first profile 4 and the second profile 9 are installed in the installation grooves 7;

[0031] Partition points 3 for partitioning the first profile 4, the second profile 9, the third profile 5 and the fourth profile 10 are provided on the first profile 4, the second profile 9, the third profile 5 and the fourth profile 10, and heat insulation connection blocks 11 are installed on the partition points 3.

[0032] Regarding the heat insulation installation points: as Figure 2 shown, the end faces of the first profile 4 and the second profile 9 close to the third profile 5 and the fourth profile 10 are provided with first connection blocks, the end faces of the third profile 5 and the fourth profile 10 close to the first profile 4 and the second profile 9 are provided with second connection blocks, and the heat insulation installation points are fixed through the first connection blocks and the second connection blocks.

[0033] The heat insulation blocks, the heat insulation connection blocks 11 and the heat insulation strips 8 are made of the same material, which is PA66 material. The heat insulation effect of PA66 material has the highest cost performance and is the most commonly used;

[0034] Both the heat insulation cavity 6 and the cavity body adopt a large cavity layout to reduce the heat of thermal radiation;

[0035] The first profile 4 and the second profile 9 are isolated by the heat insulation strip 8 to achieve a heat break between the first profile 4 and the second profile 9, and then the heat insulation from outdoors to indoors is completed. Specifically: the end faces of the installation grooves 7 are all tapered grooves, and both ends of the heat insulation strip 8 are cones with shapes adapted to the tapered grooves to achieve the stable installation and fixation of the heat insulation strip 8;

[0036] As Figure 2As shown, improvements are made to the first profile 4, the second profile 9, the third profile, and the fourth profile 10 of the present device. The partition point 3 is used to separate the first profile 4, the second profile 9, the third profile 5, and the fourth profile 10 into two parts, and the heat insulation connection block 11 adopts a multi-point co-body structure.

[0037] The pressure equal to the insulating temperature does not have to be applied to the heat insulation strip 8, and the heat insulation connection block 11 initially shares the pressure.

[0038] However, such a setting will affect the stability of the overall structure of the first profile 4, the second profile 9, the third profile 5, and the fourth profile 10.

[0039] Therefore, improvements are made to the heat insulation connection block 11 in this case, and the heat insulation connection block 11 is provided with a multi-point co-body structure.

[0040] Regarding the multi-point co-body structure:

[0041] As Figure 3 shown, the multi-point co-body structure includes a main body 13 and protrusions provided on the upper end surface and the lower cross-section of the main body 13. Slots 12 corresponding to the protrusions in number and position are provided at the positions of the multi-point co-body structure on the first profile 4, the second profile 9, the third profile 5, and the fourth profile 10, and the protrusions are snap-fitted with the slots 12.

[0042] The design of multiple protrusions and multiple slots 12 can provide sufficient stability to the multi-point co-body structure, and the multiple protrusions are designed based on the main body 13, and the main body 13 will in turn provide stability to the protrusions. Since the protrusions are inserted into the slots 12, this snap-fitting form can further improve the connection stability. Therefore, even if the stability of the overall structure of the first profile, the second profile 9, the third profile 5, and the fourth profile 10 is affected, with the help of the multi-point co-body structure, this influence can be reduced to the minimum.

[0043] Specific implementation process:

[0044] As Figure 1 shown, the present device is applicable in the field of doors and windows 2. A heat insulation connection block 11 is installed on the partition point 3, and multi-chamber multi-panel doors and windows 2 are installed and fixed by using the heat insulation connection. The multi-chamber multi-panel doors and windows 2 are installed on the door and window frame 1, and the door and window frame 1 is an integrated part of the first profile 4, the second profile 9, the third profile 5, and the fourth profile 10.

[0045] The present device solves the problem of poor heat insulation effect of traditional broken bridge aluminum profiles.
