[0060] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0061] like Figure 1-11 As shown, a door and window quick installation structure and an installation method thereof in one embodiment of the present invention include a telescopic component 1, a fixed component 2, and a limiting paddle 3, wherein the limiting paddle 3 is movably installed between the window frame 4 and the embedded sub-frame 5; the position of the fixed component 2 corresponds to the position of the limiting paddle 3; the fixed component 2 connects the telescopic component 1 and the window frame 4, and the telescopic component 1 is located between the fixed component 2 and the limiting paddle 3; the limiting paddle 3 is provided with a limiting hole 310, the telescopic end of the telescopic component 1 abuts against the limiting paddle 3, and the limiting paddle 3 moves to move the limiting hole 310 toward the direction of the telescopic component 1. When the telescopic end of the telescopic component 1 corresponds to the position of the limiting hole 310, the telescopic end of the telescopic component 1 extends, so that the telescopic component 1 is installed on the embedded sub-frame 5.

[0062] The above-mentioned door and window whole window quick installation structure is provided with a limiting paddle 3. In the door and window production workshop, the telescopic component 1 is retracted between the window frame 4 and the limiting paddle 3 through the limiting paddle 3. During the installation process between the window frame 4 and the embedded sub-frame 5, the telescopic component 1 can be extended from the limiting hole 310 and then extended into the embedded sub-frame 5 through the movement of the limiting paddle 3 and the setting of the limiting hole 310 of the limiting paddle 3. The door and window whole window quick installation structure 7 is applied to the installation of prefabricated doors and windows. The prefabricated doors and windows can be installed as a whole in the door and window production workshop and then installed with the embedded sub-frame, making the installation process of the prefabricated doors and windows simple and fast, and the installation efficiency is high.

[0063] Specifically, the telescopic component 1 is fixedly installed on the window frame 4 through the fixing component 2, and the telescopic component 1 is located between the fixing component 2 and the limiting paddle 3. The telescopic end of the telescopic component 1 is against the limiting paddle 3. As the limiting paddle 3 moves, when the limiting hole 310 corresponds to the position of the telescopic component 1, the support of the limiting paddle 3 on the telescopic component 1 is released. At this time, the telescopic end of the telescopic component 1 extends out, passes through the limiting hole 310 and extends into the embedded sub-frame 5, thereby fixing the entire door and window quick installation structure 7 to the embedded sub-frame 5.

[0064] In one embodiment, the telescopic assembly 1 includes a moving part 11, a support part 12 and a telescopic spring 13; the moving part 11 is sleeved on the support part 12, and the telescopic spring 13 is installed between the moving part 11 and the support part 12. Specifically, when the end of the moving part 11 is against the limiting paddle 3, the telescopic spring 13 is compressed between the moving part 11 and the support part 12; when the limiting paddle 3 moves so that the end of the moving part 11 is relative to the position of the limiting hole 310, the telescopic spring 13 extends, so that the end of the moving part 11 extends into the embedded sub-frame 5, thereby fixing the doors and windows.

[0065] In one embodiment, the support member 12 includes a support top plate 121 and a support shaft 122, and the support top plate 121 is fixedly connected to the support shaft 122; the movable member 11 is provided with a cavity 110, and the support shaft 122 extends into the cavity 110; the telescopic spring 13 is sleeved on the support shaft 122, and the telescopic spring 13 connects the support top plate 121 and the movable member 11. When the end of the movable member 11 abuts against the limiting paddle 3, the telescopic spring 13 contracts between the support top plate 121 and the movable member 11. When the end of the movable member 11 corresponds to the position of the limiting hole 310 of the limiting paddle 3, the telescopic spring 13 extends, so that the movable member 11 moves along the extension direction of the support shaft 122 and extends into the embedded sub-frame 5, thereby connecting the window frame 4 and the embedded sub-frame 5 to each other. The support shaft 122 plays a supporting and guiding role in the movement of the movable member 11. In addition, as Figure 5 As shown, a moving part edge 111 is provided on the peripheral side of the top of the moving part 11, one end of the telescopic spring 13 is fixedly connected to the support top plate 121, and the other end of the telescopic spring 13 is fixedly connected to the moving part edge 111. The setting of the moving part edge 111 makes the telescopic spring 13 more stable and reliable during the telescopic process.

[0066] In one embodiment, the fixing assembly 2 includes a fixing member 21, a locking member 22 and an elastic sheet 23; the window frame 4 is provided with a positioning groove 410 adapted to the fixing member 21, and the fixing member 21 is installed in the positioning groove 410; the locking member 22 connects the telescopic assembly 1 and the fixing member 21, and the elastic sheet 23 is installed between the fixing member 21 and the support member 12, and the elastic member plays a buffering role in the connection between the fixing member 21 and the support member 12.

[0067] like Figure 6As shown, the window frame 4 includes an upper frame edge 41, a lower frame edge 42 and two side frame edges, and the upper frame edge 41, the lower frame edge 42 and the two side frame edges form a chamber, the upper frame edge 41 is provided with a positioning groove 410, and the lower frame edge 42 is provided with a connecting groove 420. The positions of the positioning groove 410 and the connecting groove 420 correspond to each other, and the fixing part 21 is installed in the positioning groove 410. When the telescopic component 1 is fixed to the fixing component 2, the telescopic component 1 passes through the connecting groove 420 and abuts against the limiting paddle 3. During the telescopic process of the telescopic component 1, the moving part 11 moves along the groove wall of the connecting groove 420, and the connecting groove 420 plays a guiding role. In addition, when the telescopic component 1 is telescoped to the embedded frame, the edge 111 of the moving part abuts against the groove edge of the connecting groove 420, which limits the movement of the moving part 11, making the telescopic component 1 more stable and reliable.

[0068] In addition, the circumferential side of the fixing part 21 is recessed inward to form a sealing groove 211, and a sealing part 212 is provided in the sealing groove 211. The sealing part 212 is located at the connection between the fixing part 21 and the upper frame. At this time, the fixing part 21 is equivalent to the process hole cover of the window frame 4, which can ensure the watertightness of the cavity of the window frame 4. At the same time, as the process hole cover of the window frame 4, it can be sprayed in the same color as the window frame 4 to ensure the aesthetics of the window frame 4.

[0069] In one embodiment, the fixing member 21 is provided with a fixing groove 210 adapted to the locking member 22; the end of the support shaft 122 is connected to the connection between the support top plate 121 and the installation guide groove 120; the locking member 22 passes through the installation guide groove 120 and the fixing groove 210 in sequence, so that the support member 12 is locked to the fixing member 21.

[0070] It is worth noting that the locking member 22 is a screw, and the shape of the fixing groove 210 matches the shape of the screw's nut. This allows the locking member 22 to lock the fixing member 21 and the telescopic assembly 1 so that the end face of the fixing member 21 and the end face of the nut are aligned, ensuring the aesthetics of the door and window quick-installation structure 7 when installed on the window frame 4. Accordingly, the inner side of the installation guide 120 is provided with threads that match the threads of the screw. During the tightening process of the locking member 22, the screw extends into the installation guide 120. As the screw is tightened, the telescopic assembly 1 moves toward the direction of the fixing plate, thereby locking the telescopic assembly 1 to the fixing plate. The screws achieve a rigid connection between the fixing member 21 and the support member 12, thereby increasing the service life of the door and window quick-installation structure 7. Preferably, the screws of the fixing member 21 are countersunk screws.

[0071] In one embodiment, the elastic sheet 23 includes a positioning plate 231 and a plurality of bending plates 232, and the plurality of bending plates 232 are arranged on both sides of the positioning plate 231; a first angle α is provided between the positioning plate 231 and the bending plate, and a second angle β is provided between two adjacent bending plates 232; the positioning plate 231 is provided with a positioning hole 2310, and the positioning hole 2310 is sleeved on the locking member 22, so that the elastic sheet 23 is located between the fixing member 21 and the supporting top plate 121.

[0072] like Figure 7-9 As shown, the first angle α is greater than 90°, and the second angle β is 90°-180° or 0°-90°. The positioning hole 2310 is sleeved on the locking member 22, and the positioning plate 231 is aligned with the fixing member 21. At this time, the connection between the two adjacent bent plates 232 is against the support top plate 121. When the locking member 22 is not locked between the fixing member 21 and the support member 12, the second angle β is 0°-90°. As the locking member 22 locks the fixing member 21 and the support member 12, the support member 12 moves toward the direction of the fixing plate, causing the distance between the support top plate 121 and the fixing member 21 to gradually decrease. In turn, the elastic plate 23 is subjected to pressure from the support top plate 121, and the second angle β gradually increases. At this time, the second angle β is 90°-180°. The elastic plate 23 acts as a buffer for the connection between the telescopic assembly 1 and the fixing plate, making the connection between the telescopic assembly 1 and the window frame 4 more stable and reliable.

[0073] In one embodiment, the limiting paddle 3 includes a limiting base plate 31, a toggling edge 32 and multiple limiting edges 33; the toggling edge 32 can be folded and installed at one end of the limiting base plate 31; multiple limiting edges 33 are installed on the limiting base plate 31, and the number of the multiple limiting edges 33 is adapted to the number of hook edges 43 of the window frame 4, and the hook edges 43 are clamped on the limiting edges 33.

[0074] like Figure 6 As shown, both side frame edges of the window frame 4 are extended in the direction of the limiting paddle 3 and are provided with hook edges 43. At the same time, a limiting edge 33 is provided at a position opposite to the limiting paddle 3 and the hook edge 43. The number and position of the limiting edges 33 correspond to the number and position of the hook edges 43, so that the limiting paddle 3 is stuck in the window frame 4. At the same time, a toggle edge 32 is provided on one side of the limiting paddle 3. During use, the limiting paddle 3 can be moved along the hook edge 43 of the window frame 4 by pushing the toggle edge 32.

[0075] It is worth noting that the connection between the toggle edge 32 and the limiting bottom plate 31 is foldable. When the window frame 4 equipped with the door and window quick installation structure 7 is installed on the embedded sub-frame 5, the toggle edge 32 can be repeatedly folded to facilitate the installation of the window frame 4. In addition, a tearing notch is provided between the toggle edge 32 and the limiting bottom plate 31. When the limiting paddle 3 is moved to the specified position, the toggle edge 32 can be disconnected from the limiting bottom plate 31 through the tearing notch, facilitating the subsequent installation of the window frame 4.

[0076] In one embodiment, the door and window quick installation structure 7 also includes a positioning member 6, which is located between the window frame 4 and the embedded sub-frame 5; the positioning member 6 includes a positioning base plate 61, a first positioning edge 62 and a second positioning edge 63; the first positioning edge 62 and the second positioning edge 63 are respectively perpendicular to the two ends of the positioning base plate 61, and the extension direction of the first positioning edge 62 is set opposite to the extension direction of the second positioning edge 63; the first positioning edge 62 is against the window frame 4, and the second positioning edge 63 is against the embedded sub-frame 5.

[0077] like Figure 4 As shown, the embedded sub-frame 5 is provided with a mounting groove 50. When the window frame 4 is installed on the embedded sub-frame 5, to ensure that the notch of the mounting groove 50 and the notch of the positioning groove 410 are in the same straight line, a positioning member 6 is provided between the window frame 4 and the embedded sub-frame 5. The first positioning edge 62 of the positioning member 6 extends toward the direction of the window frame 4, so that the window frame 4 and the first positioning edge 62 abut against each other. At the same time, the second positioning edge 63 of the positioning member 6 extends toward the direction of the embedded sub-frame 5 and extends into the mounting groove 50 to abut against the notch of the mounting groove 50. The positioning member 6 is fixed to the embedded sub-frame 5, providing support for the window frame 4. In addition, the provision of the positioning member 6 also provides clearance for the movement of the limiting paddle 3 between the window frame 4 and the embedded sub-frame 5. The connection between the positioning member 6 and the embedded sub-frame 5 is a screw connection.

[0078] It is worth noting that a locking assembly 51 is provided in the mounting groove 50, and the locking assembly 51 includes a locking edge 511 and a compression member 512. There are two locking edges 511, and a locking groove is formed between the two locking edges 511. The compression member 512 is installed in the locking groove. When the telescopic spring 13 drives the movable member 11 to extend into the mounting groove 50 and resist against the compression member 512, the compression member 512 is subjected to the pressure of the telescopic spring 13 and is compressed toward the bottom of the locking groove. At this time, the movable member 11 is stuck in the locking groove as the compression member 512 is compressed, thereby fixing the movable member 11 to the embedded sub-frame 5.

[0079] Specifically, such as Figure 11As shown, the compression member 512 includes a compression spring 5121, a telescopic rod body 5124, an upper pressure plate 5122, and a lower pressure plate 5123. The upper pressure plate 5122 and the lower pressure plate 5123 are arranged relative to each other, and the telescopic rod body 5124 connects the upper pressure plate 5122 and the lower pressure plate 5123. The compression spring 5121 is sleeved on the telescopic rod body 5124. When the upper pressure plate 5122 is subjected to the pressure applied by the movement of the moving member 11, the compression spring 5121 is compressed toward the direction of the lower pressure plate 5123. At the same time, the telescopic rod body 5124 contracts, and the telescopic rod body 5124 guides the compression of the compression spring 5121. In addition, the material of the two locking edges 511 is flexible material, and the depth of the locking groove is adapted to the height of the compression member 512 when it is not compressed. As the compression member 512 is compressed, the moving member 11 extends into the locking groove, and the two locking edges 511 lock the moving member 11.

[0080] The present invention also provides a method for installing assembled doors and windows, comprising the following steps:

[0081] (1) Install the limiting paddle 3 so that the position of the limiting paddle 3 corresponds to the position of the positioning groove 410, and the positioning groove 410 is staggered with the limiting hole 310;

[0082] (2) Extend the end of the locking member 22 from the fixed through slot 210 of the fixing member 21 into the mounting guide slot 120 of the telescopic assembly 1, lock the locking member 22, and deform the elastic sheet 23, so that the telescopic assembly 1 is locked to the fixing assembly 2;

[0083] (3) The telescopic assembly 1 passes through the positioning groove 410 of the window frame 4, so that the end of the movable member 11 abuts against the limiting paddle 3, and then the telescopic assembly 1 is compressed in the direction of the limiting paddle 3, so that the fixed plate is stuck in the positioning groove 410;

[0084] (4) Repeat steps (1) to (3) to install multiple door and window quick installation structures 7 on the window frame 4, then install the glass on the window frame 4 to assemble them into assembled doors and windows, and transfer the assembled doors and windows to the embedded sub-frame 5;

[0085] (5) A plurality of positioning members 6 are installed on the embedded sub-frame 5, and the assembled doors and windows are pressed against the positioning base plates 61 of the positioning members 6, so that the assembled doors and windows are installed on the embedded sub-frame 5;

[0086] (6) Move the limiting paddle 3 to move the limiting hole 310 in the direction of the moving part 11. When the moving part 11 corresponds to the position of the limiting hole 310, the telescopic spring 13 extends, causing the end of the moving part 11 to extend into the embedded sub-frame 5, thereby fixing the assembled door and window to the embedded sub-frame 5.

[0088] Specifically, a plurality of positioning members 6 are installed on the outer side of the embedded sub-frame 5. The process of installing the assembled door and window on the embedded sub-frame 5 is as follows: the assembled door and window are moved toward the direction where the positioning member 6 is located, so that the four sides of the assembled door and window are all against the positioning base plate 61 of the positioning member 6, until the outer side of the assembled door and window is against the first positioning edge 62, and the assembled door and window are installed in place. At this time, the positioning groove 410 and the installation groove 50 are in the same straight line, and then the operation of step (6) is performed.

[0089] In one embodiment, in step (4), a plurality of door and window quick-installation structures 7 are evenly arranged and installed on the window frame 4; the distance between two adjacent door and window quick-installation structures 7 is less than or equal to 400 mm; in step (5), a plurality of positioning members 6 are evenly arranged on the embedded sub-frame 5; the distance between two adjacent positioning members 6 is less than or equal to 80 mm.

[0090] Specifically, multiple door and window quick installation structures 7 are installed on the four sides of the window frame 4. The number of door and window quick installation structures 7 can be changed according to the specifications of the assembled doors and windows. The distance between the door and window quick installation structure 7 at the end of the edge close to the window frame 4 and the end is less than or equal to 150 mm, and the distance between two adjacent door and window quick installation structures 7 is less than or equal to 400 mm.

[0091] In addition, in order to ensure the stability of the support of the prefabricated doors and windows by the positioning parts 6, there are multiple positioning parts 6, and multiple positioning parts 6 are installed on the four sides of the embedded sub-frame 5. The positions of the positioning parts 6 and the quick installation structure 7 of the door and window are staggered, and the distance between two adjacent positioning parts 6 is less than or equal to 80 mm. If the prefabricated door and window is provided with a middle stile, a positioning part 6 is added on the lower side of the position corresponding to the middle stile to further improve its stability.
