During use, the door and window sub-frame is installed first, and then the window plastering process can be carried out without installing the main frame of the door and window, avoiding pollution and deformation of the door and window. After the plastering process is completed, the main frame of the door and window is installed into the door and window sub-frame.

[0003] In the related art, for example, the Chinese patent document with the publication number CN115788228A discloses a building door and window sub-frame, a door and window structure and an installation method thereof.

The inner side wall of the sub-frame has a number of first mounting holes arranged in sequence. One end of the first connecting member is a first rod cap, and the other end is a threaded end. The second connecting member has a threaded hole, an annular slot and a nut portion. The threaded end is threadedly connected to the threaded hole, and the annular slot is used to connect with the main frame. During installation, after the first rod cap extends into the first mounting hole, it cannot rotate, then the threaded end is connected to the threaded hole, the annular slot is stuck on the main frame, and then the nut portion is rotated with a wrench until it is tightened, so that the sub-frame is fixed to the assembled frame.

[0004] In view of the above related art, during the installation process, the installer needs to tighten a plurality of nut portions on the sub-frame with a wrench in sequence, which is cumbersome to operate and has low installation efficiency. Summary of the Invention

Detailed implementation manners

[0023] The following Figures 1 - 5 is a further detailed description of the present application.

[0024] The embodiment of the present application discloses a building door and window sub-frame. Referring to Figure 1 and Figure 2 , the building door and window sub-frame includes a sub-frame 1, the sub-frame 1 is installed on the building opening and is used for installing the main frame 14 of the door and window. A plurality of installation grooves 2 are circumferentially formed on the inner side of the sub-frame 1. Specifically, two installation grooves 2 are formed on each inner side wall of the sub-frame 1. An abutting block 3 and a limiting block 4 are slidably arranged in each installation groove 2. The sliding directions of the abutting block 3 and the limiting block 4 are both perpendicular to the plane where the corresponding inner side wall of the sub-frame 1 is located. The arrangement directions of the abutting block 3 and the limiting block 4 in the same installation groove 2 are parallel to the length direction of the corresponding side edge of the sub-frame 1.

[0025] Referring to Figure 1 and Figure 2, a first elastic member for supporting the abutting block 3 to extend out of the corresponding installation groove body 2 is arranged in each installation groove body 2. The side of the abutting block 3 away from the corresponding installation groove body 2 is an arc surface, and the arc surface is used for relative sliding with the outer side of the main frame 14, so that when the main frame 14 is moved into the auxiliary frame 1, the outer side of the main frame 14 can simultaneously push a plurality of abutting blocks 3 to move towards the direction of the corresponding installation groove body 2; the limiting block 4 is used for plugging and matching with the outer side of the main frame 14, and a transmission mechanism is arranged in the installation groove body 2, and the transmission mechanism is used for driving the corresponding limiting block 4 to slide away from the installation groove body 2 when the abutting block 3 slides towards the direction close to the installation groove body 2.

[0026] During installation, first install and fix the auxiliary frame 1 into the building opening. At this time, the abutting block 3 and the limiting block 4 on the auxiliary frame 1 are in the initial state. The initial state of the abutting block 3 and the limiting block 4 means that the abutting block 3 extends out of the corresponding installation groove body 2, and the limiting block 4 is located in the corresponding installation groove body 2 and the surface of the limiting block 4 away from the installation groove body 2 is flush with the plane on the corresponding inner side of the auxiliary frame 1; then perform the plastering process at the building opening. After the plastering process is completed, move the main frame 14 into the auxiliary frame 1, so that the outer side of the main frame 14 slides relatively with the arc surfaces of a plurality of abutting blocks 3 on the inner side of the auxiliary frame 1. The main frame 14 presses a plurality of abutting blocks 3 to move towards the direction close to the corresponding installation groove body 2 at the same time. The abutting block 3 drives the corresponding limiting block 4 to slide away from the installation groove body 2 through the transmission mechanism, so that the limiting block 4 is plugged with the outer side of the main frame 14, thereby realizing the installation and fixation of the main frame 14 and the auxiliary frame 1, and there is no need to use external tools such as wrenches to tighten the nuts in turn, making the installation work of the door and window structure simple and fast, which helps to improve the installation efficiency.

[0027] Refer to Figure 1 and Figure 2 , there is a certain distance between the limiting block 4 and the abutting block 3. Among them, the limiting block 4 located on the inner wall in the vertical direction of the auxiliary frame 1 is located below the corresponding abutting block 3; a blocking block 5 is fixedly connected in the installation groove body 2 through two screw rods 16. The blocking block 5 is located between the abutting block 3 and the corresponding limiting block 4, and the side of the abutting block 3 close to the corresponding limiting block 4 abuts against the blocking block 5, and the side of the limiting block 4 close to the corresponding abutting block 3 abuts against the blocking block 5, so as to be able to guide the sliding of the abutting block 3 and the limiting block 4.

[0028] Refer to Figure 2, the blocking block 5 divides the installation groove body 2 into a first installation groove 201, a connection channel 202 and a second installation groove 203. The abutting block 3 is located in the first installation groove 201, the limiting block 4 is located in the second installation groove 203, one end of the connection channel 202 communicates with the first installation groove 201, and the other end communicates with the second installation groove 203. Opening the installation groove body 2 in a complete groove shape on the installation groove body 2 helps the overall installation of the abutting block 3, the limiting block 4 and the transmission mechanism. The setting of the blocking block 5 can guide and limit the sliding of the abutting block 3 and the limiting block 4, so that the two are not prone to unnecessary displacement.

[0029] Referring to Figure 2 , to facilitate supporting the abutting block 3 to extend out of the corresponding installation groove body 2, the first elastic member includes a support spring 17. Each abutting block 3 corresponds to two support springs 17. The support springs 17 are located in the first installation groove 201. The extending direction of the support spring 17 is parallel to the sliding direction of the corresponding abutting block 3. One end of the support spring 17 is fixed to the bottom wall of the first installation groove 201, and the other end is fixed to the surface of the abutting block 3 close to the bottom wall of the first installation groove 201; when the support spring 17 is in a natural state, the arc surface of the abutting block 3 extends out of the corresponding first installation groove 201. Through the setting of the support spring 17, when the abutting block 3 is not affected by an external force, its arc surface can extend out of the first installation groove 201 to maintain the initial state. In other embodiments, the support spring 17 can be replaced by an arc-shaped elastic sheet. Through the setting of the elastic sheet, the arc surface of the abutting block 3 can also extend out of the first installation groove 201 when the abutting block 3 is not affected by an external force, and during the relative sliding process between the main frame 14 and the arc surface, the abutting block 3 can be compressed to retract into the first installation groove 201.

[0030] Referring to Figure 2 , to facilitate the abutting block 3 to drive the corresponding limiting block 4 to slide away from the installation groove body 2 when sliding towards the direction close to the corresponding installation groove body 2, the transmission mechanism includes a pushing spring 6, a limiting component and an unlocking component 11. The pushing spring 6 is located in the second installation groove 203. Each limiting block 4 corresponds to two pushing springs 6. The pushing springs 6 are located on the side of the corresponding limiting block 4 close to the bottom wall of the second installation groove 203. The extending direction of the pushing spring 6 is parallel to the sliding direction of the corresponding limiting block 4. One end of the pushing spring 6 is fixed to the bottom wall of the second installation groove 203, and the other end is fixed to the surface of the corresponding limiting block 4 close to the bottom wall of the second installation groove 203. The pushing spring 6 is used to push the limiting block 4 to slide away from the corresponding second installation groove 203. When the surface of the limiting block 4 away from the corresponding second installation groove 203 is flush with the plane of the inner wall of the corresponding side of the attached frame 1, the pushing spring 6 is in a compressed state.

[0031] Referring to Figure 2The limit assembly is arranged in the connecting channel 202, and the limit assembly is used to limit the initial position of the limit block 4. The unlocking assembly 11 is arranged in the first mounting groove 201. The unlocking assembly 11 is used to release the limit assembly from limiting the limit block 4 when the abutting block 3 slides in the direction close to the corresponding first mounting groove 201. The initial position of the limit block 4 is that the side of the limit block 4 away from the second mounting groove 203 is flush with the plane of the inner wall of the corresponding side of the attached frame 1.

[0032] Reference Figure 2 and Figure 3 In order to facilitate the limitation of the initial position of the limit block 4, the limit assembly includes a rotating rod 7, a limit claw 8 and a second elastic member. The rotating rod 7 is rotatably arranged in the connecting channel 202, and the rotation axis of the rotating rod 7 is perpendicular to the arrangement direction of the corresponding limit block 4 and the abutment block 3. Further, the rotation axis of the rotating rod 7 is perpendicular to the sliding direction of the corresponding limit block 4, and the rotating rod 7 is located between the two pushing springs 6; a rotating shaft 18 is fixedly penetrated in the middle of the rotating rod 7, and the rotating shaft 18 rotates in the connecting channel 202. The rotating shaft 18 is located on one side of the two screws close to the second mounting groove 203, and the limit claw 8 is fixedly arranged at one end of the rotating rod 7 away from the bottom wall of the second mounting groove 203. A claw groove 9 is provided on a side of the limit block 4 close to the corresponding abutment block 3, which is plugged and matched with the limit claw 8. When the limit claw 8 is plugged and matched with the claw groove 9, the limit block 4 is in the initial state. The second elastic member is arranged in the connecting channel 202, and the second elastic member is used to drive the end of the rotating rod 7 close to the limiting claw 8 to rotate toward the direction close to the claw groove 9. The unlocking component 11 is used to press the end of the rotating rod 7 away from the limiting claw 8 when the abutment block 3 slides toward the direction close to the corresponding first installation groove 201 to unlock the plug-in cooperation between the limiting claw 8 and the claw groove 9.

[0033] Reference Figure 2 and Figure 3 In order to facilitate the end of the rotating rod 7 close to the limiting claw 8 to rotate in the direction close to the claw groove 9, the second elastic member includes a torsion spring 10 movably sleeved on the rotating shaft 18, one end of the torsion spring 10 is fixed on the inner wall of the connecting channel 202, and the other end is fixed on the rotating rod 7. When the torsion spring 10 is in a natural state, the end of the rotating rod 7 close to the limiting claw 8 is inclined in the direction away from the corresponding abutment block 3. When the limiting block 4 is in the initial state, the limiting claw 8 is plugged into the corresponding claw groove 9, and the push spring 6 is in a compressed state. At this time, under the action of the torsion spring 10, the limiting claw 8 will not be separated from the corresponding claw groove 9, thereby ensuring that the limiting block 4 maintains the initial state.

[0034] Reference Figure 2 and Figure 3, to facilitate pressing the end of the rotating rod 7 away from the limiting claw 8 when the abutting block 3 slides toward the direction close to the corresponding first installation groove 201, the unlocking assembly 11 includes a counterweight ball 111 and an elastic ring 112. The counterweight ball 111 is movably arranged in the first installation groove 201. The counterweight ball 111 is located on the side of the abutting block 3 close to the bottom wall of the first installation groove 201. The counterweight ball 111 is located between two corresponding support springs 17. The gravity of the counterweight ball 111 is greater than the torsion force of the torsion spring 10. The counterweight ball 111 is aligned with the end of the rotating rod 7 away from the limiting claw 8. The gravity of the counterweight ball 111 is less than the elastic force of the support spring 17, so that the counterweight ball 111 located in the upper installation groove body 2 of the auxiliary frame 1 will not completely push the corresponding abutting block 3 out of the first installation groove 201.

[0035] Refer to Figure 2 and Figure 3 , a support plate 19 is fixed between the blocking block 5 and the connecting channel 202. A through hole is formed in the support plate 19. The through hole is located between two corresponding screw rods 16 of the blocking block 5. The elastic ring 112 is fixedly arranged in the through hole. The elastic ring 112 is one of a rubber ring, a silica gel ring or a plastic ring, and there is no limitation here; the inner diameter of the elastic ring 112 is smaller than the diameter of the counterweight ball 111, and the outer diameter of the elastic ring 112 is larger than the diameter of the counterweight ball 111. In the initial state, the counterweight ball 111 is clamped in the elastic ring 112 and fixed by double-sided adhesive; the distance from the surface of the abutting block 3 close to the corresponding limiting block 4 to the surface of the corresponding limiting block 4 close to the abutting block 3 is greater than the distance from the center of the corresponding counterweight ball 111 to the plane of the corresponding limiting block 4 close to the abutting block 3 in the initial state, so that the abutting block 3 can abut against the counterweight ball 111 to pass through the elastic ring 112 during the process of sliding close to the bottom wall of the first installation groove 201; when the auxiliary frame 1 is in the initial state, the end of the rotating rod 7 away from the limiting claw 8 is close to the side of the corresponding counterweight ball 111 close to the second installation groove 203.

[0036] When the abutting block 3 slides toward the direction close to the bottom wall of the first installation groove 201, the abutting block 3 presses the surface of the corresponding counterweight ball 111, so that the counterweight ball 111 gradually slides toward the direction close to the second installation groove 203 through the elastic ring 112. Then, the counterweight ball 111 presses the end of the corresponding rotating rod 7 away from the limiting claw 8, so that the limiting claw 8 is disengaged from the claw groove 9 on the corresponding limiting block 4, realizing the unlocking of the limiting block 4. Then, the compressed pushing spring 6 has a tendency to push the limiting block 4 toward the direction away from the second installation groove 203, so as to facilitate the connection with the main frame 14.

[0037] Refer to Figure 2 and Figure 3, one end of the rotating rod 7 away from the limiting claw 8 is fixed with a limiting convex block 12, and the limiting convex block 12 is rectangular; one side of the limiting block 4 close to the bottom wall of the second installation groove 203 is fixed with a limiting extension rod 13, and the length direction of the limiting extension rod 13 is parallel to the sliding direction of the limiting block 4. The limiting extension rod 13 is located between two corresponding pushing springs 6. When the limiting block 4 is in the initial state, the surface of the limiting extension rod 13 away from the corresponding limiting block 4 is located on the side of the limiting convex block 12 away from the limiting block 4. The limiting convex block 12 is used to abut against the side of the limiting extension rod 13 away from the corresponding limiting block 4 when the limiting block 4 extends out of the corresponding second installation groove 203. An elastic rubber layer is fixed on the side of the abutting block 3 close to the corresponding limiting block 4. When the limiting convex block 12 abuts against the side of the limiting extension rod 13 away from the limiting block 4, the side of the counterweight ball 111 away from the limiting block 4 abuts against the corresponding elastic ring 112, so as to realize the limitation of the counterweight ball 111 and make the counterweight ball 111 not easy to slide.

[0038] When the counterweight ball 111 presses the limiting convex block 12 and rotates in the direction away from the corresponding first installation groove 201, since the limiting block 4 has not yet aligned with the required position on the main frame 14, the limiting block 4 does not move. As the abutting block 3 continues to approach the corresponding first installation groove 201, the rubber layer of the abutting block 3 is squeezed between the counterweight ball 111, so that the limiting convex block 12 abuts against the surface of the limiting extension rod 13 close to the corresponding abutting block 3; after the limiting block 4 aligns with the required position on the main frame 14, the pushing spring 6 pushes the limiting block 4 to move in the direction away from the second installation groove 203, causing relative sliding between the limiting extension rod 13 and the limiting convex block 12. Then the surface of the limiting extension rod 13 close to the corresponding abutting block 3 disengages from the corresponding limiting convex block 12. Under the elastic abutment of the rubber layer of the abutting block 3, the counterweight ball 111 continues to press the limiting convex block 12, so that the limiting convex block 12 abuts against the side of the limiting extension rod 13 away from the corresponding limiting block 4, thereby restricting the limiting block 4 from moving back and ensuring the connection between the limiting block 4 and the main frame 14.

[0039] The implementation principle of the building door and window sub-frame in the embodiment of the present application is as follows: during installation, first install and fix the sub-frame 1 into the building opening. At this time, the abutting block 3 and the limiting block 4 on the sub-frame 1 are in the initial state. Then, the plastering process is carried out at the building opening. After the plastering process is completed, the main frame 14 is moved into the sub-frame 1, so that the outer side of the main frame 14 slides relative to the arc surfaces of the plurality of abutting blocks 3 on the inner side of the sub-frame 1. The main frame 14 presses the plurality of abutting blocks 3 and moves in the direction close to the corresponding first installation groove 201 at the same time. Then, the abutting block 3 abuts against the corresponding counterweight ball 111, squeezes the counterweight ball 111 to slide in the direction close to the second installation groove 203 through the elastic ring 112. Then, the counterweight ball 111 presses one end of the corresponding rotating rod 7 away from the limiting claw 8, so that the limiting claw 8 disengages from the claw groove 9 on the corresponding limiting block 4, realizing the unlocking of the limiting block 4.

[0040] Since the limit block 4 is not yet aligned with the required position on the main frame 14 at this time, as the abutting block 3 continues to approach the bottom wall of the corresponding first installation groove 201, the rubber layer of the abutting block 3 is squeezed between the counterweight ball 111, causing the limit projection 12 to abut against the side of the limit extension rod 13 close to the corresponding abutting block 3. When the limit block 4 is aligned with the required position on the main frame 14, the compressed push spring 6 pushes the limit block 4 to move away from the second installation groove 203, causing relative sliding between the limit extension rod 13 and the limit projection 12 until the limit block 4 is fully inserted into the outside of the main frame 14. Then, the side of the limit extension rod 13 close to the corresponding abutting block 3 is disengaged from the corresponding limit projection 12. Under the elastic abutment of the rubber layer of the abutting block 3, the counterweight ball 111 continues to squeeze the limit projection 12, causing the limit projection 12 to abut against the side of the limit extension rod 13 away from the corresponding limit block 4, thereby restricting the limit block 4 from moving back; thus realizing the installation and fixation of the main frame 14 and the attached frame 1, without the need to use external tools such as wrenches to tighten the nuts in sequence, making the installation work of the door and window structure simple and fast, and helping to improve the installation efficiency.

[0041] The embodiment of the present application also discloses a door and window structure. Referring to Figure 4 and Figure 5 , the door and window structure includes the above-mentioned building door and window attached frame, and also includes a main frame 14. A limit groove 15 is provided on the outside of the main frame 14, and the limit grooves 15 correspond to the limit blocks 4 on the attached frame 1 one by one. The limit grooves 15 are used for plugging and matching with the corresponding limit blocks 4. The size of the main frame 14 is adapted to the size of the inside of the attached frame 1, so that there is a very small installation gap between the main frame 14 and the attached frame 1, which is filled with a foaming glue layer after installation.

[0042] The implementation principle of the door and window structure in the embodiment of the present application is as follows: After the attached frame 1 is installed and the plastering process of the building opening is completed, align the main frame 14 with the attached frame 1, and align the limit grooves 15 on the main frame 14 with the corresponding limit blocks 4. Then gradually move the main frame 14 into the attached frame 1, so that the outer side of the main frame 14 and the arc surfaces of the multiple abutting blocks 3 on the inner side of the attached frame 1 undergo relative sliding. Since the limit grooves 15 on the outer side of the main frame 14 are not yet aligned with the corresponding limit blocks 4 in the plane of the main frame 14, the limit blocks 4 will not protrude from the corresponding first installation groove 201 under the abutment of the outer wall of the main frame 14. Then the main frame 14 moves to the position where the limit groove 15 is aligned with the corresponding limit block 4. At this time, the multiple limit blocks 4 pop out simultaneously, and the main frame 14 can be abutted and fixed at the central position inside the attached frame 1 in multiple directions without supporting the main frame 14. Each limit block 4 abuts against the bottom wall of the corresponding limit groove 15, realizing the fixation between the main frame 14 and the attached frame 1, which is simple and fast, and helps to improve the installation efficiency.

[0043] The embodiment of the present application also discloses an installation method for a door and window structure. The installation method of the door and window structure uses the above-mentioned door and window structure, and further includes the following steps: Step 1: Align the main frame 14 with the auxiliary frame 1; Step 2: Gradually move the main frame 14 into the auxiliary frame 1, so that the outer side of the main frame 14 slides relative to the arc surfaces of the plurality of abutting blocks 3, and the main frame 14 presses the plurality of abutting blocks 3 and moves towards the direction close to the corresponding first installation groove 201 at the same time; Step 3: Then, the abutting block 3 abuts against the corresponding counterweight ball 111 through the elastic ring 112, so that the counterweight ball 111 presses the corresponding rotating rod 7, realizing the separation of the limiting claw 8 from the claw groove 9, unlocking the sliding of the limiting block 4, and then the counterweight ball 111 abuts the limiting convex block 12 against one surface of the limiting extension rod 13 close to the corresponding abutting block 3. Then, the main frame 14 moves until the limiting groove 15 is aligned with the corresponding limiting block 4. At this time, the plurality of limiting blocks 4 slide synchronously away from the second installation groove 203 under the action of the compressed pushing spring 6, so that the limiting blocks 4 are completely inserted and matched with the corresponding limiting grooves 15 on the main frame 14. Then, under the abutment of the rubber layer of the abutting block 3, the counterweight ball 111 further presses the limiting convex block 12, so that the limiting convex block 12 abuts against the side of the corresponding limiting extension rod 13 away from the corresponding limiting block 4, restricting the return movement of the limiting block 4, and realizing the fixed connection between the main frame 14 and the auxiliary frame 1.

[0044] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
