[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides Figure 1 As shown, an aluminum alloy thermal insulation profile with a double insulation layer comprises a first profile 1, second profiles 2 are symmetrically arranged on both sides of the first profile 1, adjustment holes 23 are provided on the outer surfaces of the opposite sides of the two second profiles 2 near the top, bolts 72 are provided between the inner walls of the adjustment holes 23, a first limiting groove 24 is provided on the top of the second profile 2 near the middle, a second limiting block 71 is slidably connected between the inner surfaces of the first limiting groove 24, second limiting grooves 25 are symmetrically provided on the top of the second profile 2 near the two sides, a first limiting block 7 is slidably connected between the inner surfaces of the two second limiting grooves 25, the bolt 72 threadedly penetrates the second limiting block 71, an inner wall of one side of the first limiting groove 24 and an end of the bolt 72 are rotatably connected, a first sealing connector 3 is provided between the outer surfaces of the opposite sides of the first profile 1 and the second profile 2, a second sealing connector 4 is provided above the first sealing connector 3, first card grooves 11 are provided on the outer surfaces of both sides of the two first profiles 1 near the bottom, and the first A second groove 12 is provided near the middle of the outer surfaces of both sides of the profile 1, the positions on both sides of the outer surface of the first sealing connector 3 are slidably connected to the inner walls of the first groove 11 and the third groove 21 respectively, and the positions on both sides of the outer surface of the second sealing connector 4 are slidably connected to the inner walls of the second groove 12 and the fourth groove 22 respectively. A third profile 5 is provided on the top of the two second profiles 2, and two fifth grooves 51 are provided on the outer surfaces of the opposite sides of the two third profiles 5. A third sealing connector 6 is slidably connected between the inner walls of the two fifth grooves 51, and a vacuum glass 9 is provided between the outer surfaces of the opposite sides of the two third sealing connectors 6. The bottom of the third profile 5 is connected to the top of the second limit block 71 near the middle position, and the bottom of the third profile 5 is connected to the top of the two first limit blocks 7 near the two sides respectively. A plurality of thermal insulation cottons 8 are provided on both sides of the first profile 1, and the positions of the plurality of thermal insulation cottons 8 correspond to the positions of the first sealing connector 3 and the second sealing connector 4.

[0026] The effect achieved by the entire embodiment 1 is that when the thermal insulation strip of the thermal insulation profile is aged due to long-term use, first insert a hexagonal wrench into the adjustment hole 23 and turn the bolt 72 forward. Under the action of the rotation of the bolt 72, the second limit block 71 moves in an oblique downward direction, and the third profile 5 and the third sealing connector 6 move in an oblique downward direction at the same time. At this time, the two third sealing connectors 6 will slowly approach each other during the downward movement, thereby further squeezing and fixing the loose vacuum glass 9, ensuring the firmness of the vacuum glass 9, solving the problem that the doors and windows of the existing thermal insulation profile are easy to loosen after long-term use, and improving safety. The outer surfaces of the first sealing connector 3, the second sealing connector 4 and the third sealing connector 6 all have triangular protrusions, and the first sealing connector 3 and the second sealing connector 4 arranged on the outer surfaces of the opposite sides of the second profile 2 play a role in connecting the two second profiles 2 and the first profile 1, and because the first sealing connector 3, the second sealing connector 4 and the third sealing connector The sealing connectors 6 are all made of PA66 nylon + 25% glass fiber, and have a low thermal conductivity. Therefore, it is difficult for heat to be transferred between the first profile 1 and the second profile 2 that are not directly connected, so that the heat absorbed by the outdoor first profile 1 is difficult to be transferred to the indoor first profile 1, and has a good thermal insulation effect. The two first limit blocks 7 increase the stability of the two third profiles 5 when moving, and the thermal insulation cotton 8 plays a role in improving the thermal insulation effect. The first limit groove 24 and the second limit groove 25 play a role in limiting the first limit block 7 and the second limit block 71. The cross-sections of the first card slot 11, the second card slot 12, the third card slot 21, the fourth card slot 22, and the fifth card slot 51 are all triangular in shape, and can be plugged in and connected with the triangular protrusions on the sides of the first sealing connector 3, the second sealing connector 4 and the third sealing connector 6. The first profile 1 and the second profile 2 are both made of aluminum alloy material, which has the characteristics of light weight and high strength, and is suitable for use in construction.

[0027] Embodiment 2, as Figure 1-Figure 4 As shown, the top of the second profile 2 is inclined, and the bottom of the third profile 5 is inclined.

[0028] The effect achieved by the entire embodiment 2 is that the top of the second profile 2 is set to be inclined, and the top of the third profile 5 is set to be inclined, so under the action of gravity, the third profile 5 will drive the vacuum glass 9 to be forced downward all the time, which can ensure the fit between the third sealing connector 6 and the vacuum glass 9 to a certain extent. At the same time, it also makes it difficult for the second limit block 71 to slide upward and drive the bolt 72 to rotate, and the overall reliability is relatively high.

[0029] Working principle: When the thermal insulation strip ages due to long-term use of the thermal insulation profile, first insert a hexagonal wrench into the adjustment hole 23 and turn the bolt 72 forward. Under the action of the rotation of the bolt 72, the second limit block 71 moves in an oblique downward direction, and the third profile 5 and the third sealing connector 6 move in an oblique downward direction at the same time. At this time, the two third sealing connectors 6 will slowly approach each other during the downward movement, thereby further squeezing and fixing the loose vacuum glass 9, ensuring the firmness of the vacuum glass 9, solving the problem that the doors and windows of the existing thermal insulation profiles are easy to loosen after long-term use, and improving safety. In addition, the top of the second profile 2 is set to an inclined shape, and the top of the third profile 5 is set to an inclined shape. Therefore, under the action of gravity, the third profile 5 will drive the vacuum glass 9 to be forced downward all the time, which can ensure the fit between the third sealing connector 6 and the vacuum glass 9 to a certain extent. At the same time, it also makes it difficult for the second limit block 71 to slide upward and drive the bolt 72 to rotate, and the overall reliability is high.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
