[0027] The present invention will be further described below with reference to the embodiments.

[0028] See also Figure 1-6 The utility model provides a connection structure of door and window profiles based on lightweight materials, including an inner frame profile 1 and an outer frame profile 2. A connection mechanism 3 is provided between the inner frame profile 1 and the outer frame profile 2 for disassembling and connecting the inner frame profile 1 and the outer frame profile 2.

[0029] The connecting mechanism 3 includes a clamping assembly 31 and a positioning assembly 32 . The clamping assembly 31 is provided on the inner frame profile 1 and the outer frame profile 2 , and the positioning assembly 32 is arranged to align with the clamping assembly 31 .

[0030] The clamping assembly 31 cooperates with the positioning assembly 32 to facilitate stable connection and installation between the inner frame profile 1 and the outer frame profile 2, thereby improving the strength of the connection between the inner frame profile 1 and the outer frame profile 2, and enabling convenient installation and disassembly of the inner frame profile 1 and the outer frame profile 2, thereby improving disassembly efficiency.

[0031] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that the inner frame profile 1 and the outer frame profile 2 are made of titanium-magnesium alloy material, and multiple clamping components 31 are arranged on the inner frame profile 1 and the outer frame profile 2, and the multiple clamping components 31 are arranged at equal distances.

[0032] Further as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, it is worth mentioning that the clamping assembly 31 includes a connecting rod 311, which is arranged on the upper part of the outer frame profile 2, and a connecting bolt 312 is threadedly connected to the bottom of the connecting rod 311. The connecting rod 311 is threadedly installed on the outer frame profile 2 through the connecting bolt 312. The top of the connecting rod 311 is fixedly connected to a clamping block 313, and the clamping block 313 is positioned at the corresponding position of the lower part of the inner frame profile 1 and is provided with a clamping interface 314. The clamping block 313 is set in an elliptical sphere and protrudes from the connecting rod 311. The height of the connecting rod 311 is set to be consistent with the wall thickness of the inner frame profile 1, and the clamping interface 314 is set to match the size of the clamping block 313 at the front end and the size of the connecting rod 311 at the rear end.

[0033] The inner frame profile 1 and the outer frame profile 2 are aligned with the clamping block 313 through the front end of the clamping interface 314, and the front end opening of the through-hole 326 is aligned with the fixing frame 321, so that the inner frame profile 1 and the outer frame profile 2 are matched and installed, and the inner frame profile 1 or the outer frame profile 2 is slid so that the clamping block 313 slides in the clamping interface 314 through the connecting rod 311, and the fixing frame 321 slides through the through-hole 326, thereby achieving the clamping of the outer frame profile 2 through the clamping block 313, and further improving the clamping between the inner frame profile 1 and the outer frame profile 2 through the fixing frame 321, thereby enhancing the stability of the connection between the two.

[0034] According to the above working process, it can be known that: through the provided connecting mechanism 3, when the inner frame profile 1 and the outer frame profile 2 are connected, the clamping assembly 31 in the connecting mechanism 3 slides in position, so that the inner frame profile 1 and the outer frame profile 2 can be fixedly connected, which improves the convenience of the installation process. At the same time, the disassembly work can be achieved through the same operation, thereby improving the disassembly and assembly efficiency.

[0035] Further as Figure 2、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 When the locking cam 324 is unlocked, the locking cam 326 is unlocked and the winch 330 is unlocked.

[0036] The end of the positioning rod 322 is squeezed by the positioning plate 324, so that the positioning rod 322 slides in the fixed frame 321 and squeezes the spring 323. When sliding to the positioning rod 322 aligned with the positioning groove 325, the elastic force of the spring 323 causes the positioning rod 322 to limit the sliding between the inner frame profile 1 and the outer frame profile 2 in the positioning groove 325, thereby improving the limiting ability after the sliding installation, thereby ensuring the stability of the inner frame profile 1 and the outer frame profile 2 after connection.

[0037] This solution has the following working process: when this device is used, the inner frame profile 1 and the outer frame profile 2 are aligned with the clamping block 313 through the front end of the clamping interface 314, and the front end opening of the through-hole 326 is aligned with the fixing frame 321, so that the inner frame profile 1 and the outer frame profile 2 are matched and installed, and the inner frame profile 1 or the outer frame profile 2 is slid so that the clamping block 313 slides in the clamping interface 314 through the connecting rod 311, and the fixing frame 321 slides through the through-hole 326, thereby achieving the clamping of the outer frame profile 2 through the clamping block 313, and further improving the inner frame profile 1 and the outer frame profile 2 through the fixing frame 321. The clamping connection between the frame profiles 2 strengthens the stability of the connection between the two. At the same time, during the sliding process, the end of the positioning rod 322 is squeezed by the positioning plate 324, so that the positioning rod 322 slides in the fixed frame 321 and squeezes the spring 323. When sliding to the positioning rod 322 aligned with the positioning groove 325, the elastic force of the spring 323 causes the positioning rod 322 to limit the sliding between the inner frame profile 1 and the outer frame profile 2 in the positioning groove 325, thereby improving the limiting ability after the sliding installation, thereby ensuring the stability of the inner frame profile 1 and the outer frame profile 2 after connection.

[0038] In summary: through the setting of the connecting mechanism 3, when the inner frame profile 1 and the outer frame profile 2 are connected, the clamping component 31 in the connecting mechanism 3 is slid in position, so that the inner frame profile 1 and the outer frame profile 2 can be fixedly connected, which improves the convenience of the installation process. At the same time, the disassembly work can be achieved through the same operation, thereby improving the disassembly and assembly efficiency; through the positioning component 32 set in the connecting mechanism 3, after the connection between the inner frame profile 1 and the outer frame profile 2 is achieved through the clamping component 31, the connection process between the two can be positioned to improve the stability between the two.
