Description

Technical Field

[0001] This application relates to the field of window frame equipment technology, and in particular to a novel frame structure for replacing old windows. Background Technology

[0002] With the progress of the times, people's living standards have greatly improved, and their demands for life have also become increasingly higher. This improvement in living standards inevitably leads to increased energy consumption in society. Existing building energy-saving design standards and requirements are no longer sufficient to keep pace with the times. Furthermore, in older buildings, the installation of doors and windows now easily results in issues such as corner cracking, aging rubber strips, cracked sealant, and aging hardware that makes opening and closing difficult. Therefore, the renovation of existing building doors and windows is necessary for residents.

[0003] Current traditional window replacement methods typically involve removing the old frame, cleaning the opening, installing a new frame, and repairing the wall. This process is cumbersome and time-consuming. Cutting and chiseling operations during construction can easily cause irreversible damage to walls, window sills, and interior finishes. Furthermore, traditional methods generate significant noise, dust, and waste on-site, significantly disrupting residents' daily lives. The installation process requires repeated calibration and positioning, resulting in high labor costs and low efficiency. Uneven stress on the new window frame can also cause deformation, affecting sealing performance and structural stability.

[0004] While some existing frame-mounted renovation solutions retain the old frame, the size of each user's old window is different. Therefore, when the new frame is installed on the old frame, the new frame may be larger than the old frame. During the screw fixing process, there is a lack of self-adaptive positioning, and the new frame is prone to tilting. Furthermore, if the gap is too large, the new frame may deform, affecting its use. Summary of the Invention

[0005] In order to improve the installation efficiency of the new frame structure for replacing old windows, this application provides a new frame structure for replacing old windows.

[0006] This application provides a novel frame structure for replacing old windows, employing the following technical solution: A novel frame structure for replacing old windows includes a base frame, which is composed of a first frame plate, a second frame plate, and a third frame plate. The base frame is used to fit onto an old window frame. A positioning mechanism is installed on the third frame plate. The positioning mechanism includes a first guide rod installed on the third frame plate. A movable block is slidably installed on the first guide rod. A first spring is sleeved on the first guide rod. One end of the first spring is connected to the movable block, and the other end is connected to the second frame plate. An arc-shaped surface is formed on the bottom surface of the movable block. A pad is movably installed on the third frame plate, and a support plate is movably connected to the pad.

[0007] By adopting the above technical solution, the bottom frame can be directly fitted onto the old window frame without removing the old frame, thus avoiding damage to the wall and decoration. When fitting, the old frame is guided along the arc surface, automatically squeezing the movable block and stretching the first spring to achieve automatic pre-positioning. After releasing, the spring rebounds, causing the bottom frame to automatically clamp the old frame, quickly completing the initial fixation and significantly improving installation efficiency and positioning accuracy.

[0008] In one specific implementation, a first sliding groove is provided on the third frame plate, a pad is slidably mounted on the third frame plate through the first sliding groove, a second guide rod is installed on the third frame plate, the second guide rod passes through the pad and is slidably connected to the pad, a fixing plate is installed on the pad, a support plate is hinged on the third frame plate, a second sliding groove is provided on the support plate, and the fixing plate extends into the second sliding groove and is slidably connected to the support plate.

[0009] By adopting the above technical solution, the pad slides stably along the slide groove and guide rod, driving the fixed plate to drive the support plate to rotate, realizing the opening and retraction of the support plate, adaptively compensating for the gap between the old frame and the new frame, forming rigid support, preventing the frame from deforming under force, and improving structural stability and versatility.

[0010] In one specific implementation scheme, a third sliding groove is provided on the movable block, and a lifting plate is slidably installed on the movable block through the third sliding groove. A third guide rod is installed on one end of the lifting plate near the pad, and a telescopic sleeve for pressing the pad is slidably installed on the third guide rod. A second spring is sleeved on the third guide rod, with one end of the second spring connected to the telescopic sleeve and the other end connected to the lifting plate.

[0011] By adopting the above technical solution, the front telescopic sleeve is tightened against the pad, keeping the support plate in a retracted state, which facilitates the smooth insertion of the bottom frame. After the frame is inserted into place, the old frame pushes the lifting plate, causing the telescopic sleeve to detach from the pad. The pad and support plate then resume their movement. Tightening the screws will drive the support plate to press against the old frame, thus realizing the automated linkage of the installation process and making the operation simpler.

[0012] In one specific implementation, the third groove is a cross-shaped groove.

[0013] By adopting the above technical solution, the cross-shaped groove provides precise guidance for the lifting plate, restricting it to slide only in the vertical direction, avoiding skew and jamming, and ensuring stable and reliable clutch operation.

[0014] In one specific implementation, the second groove is a T-shaped groove.

[0015] By adopting the above technical solution, the T-slot cooperates with the fixed plate to prevent slippage, improve transmission stability, and ensure smooth rotation and firm support of the support plate.

[0016] In one specific implementation scheme, the first frame plate and the third frame plate are formed with recessed mounting grooves, and the first frame plate and the third frame plate are formed with a snap-fit ​​structure. The snap-fit ​​structure is located at the groove opening of the mounting groove, and the first frame plate and the third frame plate are snapped together with a card plate through the snap-fit ​​structure.

[0017] By adopting the above technical solution, the card plate and the bottom frame can be quickly assembled by snap-fit ​​without the need for screws. It is easy to disassemble and assemble and can be flexibly replaced according to the window sill shape, decoration and sealing requirements, adapting to a variety of scenarios.

[0018] In one specific implementation, the engaging structure includes a first lug located on both sides of the mounting groove. A first platform is formed on the side of the first lug away from the bottom of the mounting groove. A second lug is formed on the bottom frame, and the second lug is further away from the bottom of the mounting groove than the first lug.

[0019] By adopting the above technical solution, the first lug and the second lug form a multi-level limiting mechanism, providing a precise positioning and firm fastening foundation for the card plate, thereby improving the connection strength and stability.

[0020] In one specific implementation, the card plate has two cards formed for insertion into the mounting slots. The ends of the two cards away from the card plate are respectively formed with card heads. The ends of the card heads away from the cards are inclined and close to each other. The card heads and the cards have a snap-fit ​​surface. The card plate has a third lug formed, which is positioned opposite the first platform.

[0021] By adopting the above technical solution, the card elastically retracts during installation, and the card head automatically springs back and snaps shut after passing the lug. The snapping surface fits tightly with the lug, and the multi-level lugs work together to limit the movement, achieving tool-free quick snapping, and the connection is firm and not easy to loosen.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. No need to remove the old frame, direct installation, no damage to the wall and interior decoration, environmentally friendly construction, minimal interference and low cost.

[0023] 2. The positioning mechanism enables automatic guidance, pre-tightening positioning, and adaptive gap compensation, eliminating the need for repeated calibration and significantly improving installation efficiency.

[0024] 3. The combination of rigid support plates and quick-assembly clamping structure reduces frame deformation, ensures secure fixing, enhances adaptability, and provides superior sealing and energy-saving performance. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses a novel frame structure for replacing old windows, referring to... Figure 1 and Figure 2 It includes a bottom frame 1, which is integrally composed of a first frame plate 11, a second frame plate 12 and a third frame plate 13. The first frame plate 11, the second frame plate 12 and the third frame plate 13 form a U-shaped frame. The bottom frame 1 is used to fit onto the frame of the old window. The first frame plate 11 is located on the indoor side and the third frame plate 13 is located on the outdoor side.

[0035] Reference Figure 2 and Figure 3The first frame plate 11 and the third frame plate 13 are formed with recessed mounting grooves 14, which are U-shaped grooves. Engaging structures are formed on the first frame plate 11 and the third frame plate 13, located at the opening of the mounting groove 14. As shown by the engaging structure on the third frame plate 13, the engaging structure includes a first lug 151 formed on the third frame plate 13. The first lug 151 is located on both sides of the mounting groove 14. A first platform 152 is formed on the side of the first lug 151 away from the bottom of the mounting groove 14. A second lug 153 is formed on the bottom frame 1, and the second lug 153 is further away from the bottom of the mounting groove 14 than the first lug 151.

[0036] A latching plate 16 is snapped onto the first frame plate 11 and the third frame plate 13 via a snap-fit ​​structure. Two cards 161 with insertion slots 14 are formed on the latching plate 16. The ends of the two cards 161 furthest from the latching plate 16 are inclined away from each other. Each end of the two cards 161 furthest from the latching plate 16 has a latch head 162 formed. The ends of the latch heads 162 furthest from the cards 161 are inclined towards each other, and a snap-fit ​​surface 163 is formed between the latch heads 162 and the cards 161. A third lug 164 is formed on the latching plate 16, positioned opposite the first tabletop 152. A tabletop 165 is mounted on the side of the latching plate 16 furthest from the cards 161. In this embodiment, the tabletop 165 can be horizontally oriented, inclined, or of other shapes depending on the structure of the user's windowsill.

[0037] When the card plate 16 is mounted on the third frame plate 13, the card head 162 is pressed against the first lug 151. Through the action of the inclined surface of the card head 162, the card head 162 will drive the card 161 to move closer together. When the card head 162 is pressed past the first lug 151, the card 161 will open the card head 162 so that the snap-fit ​​surface 163 on the card head 162 abuts against the first lug 151, thereby completing the snap-fit ​​of the card head 162. At the same time, the card plate 16 will abut against the second lug 153 to position the card plate 16. There is a gap between the second lug 153 and the first table surface 152.

[0038] In this embodiment of the application, a latching plate 16 is also installed on the first frame plate 11 through a latching structure. Light strips, decorative strips or soft rubber pads can be installed on the latching plate 16 located on the first frame plate 11 according to the user's choice.

[0039] Reference Figure 4 and Figure 5A positioning mechanism 2 is installed on the third frame plate 13. The positioning mechanism 2 includes a first guide rod 21, which is fixedly installed on the third frame plate 13. A movable block 22 is slidably installed on the first guide rod 21. A first spring 23 is sleeved on the first guide rod 21. One end of the first spring 23 is fixedly connected to the movable block 22, and the other end is fixedly connected to the second frame plate 12. An arc-shaped surface 221 is formed on the bottom surface of the movable block 22.

[0040] When the bottom frame 1 is fitted onto the old window frame, the old window frame first abuts against the curved surface 221 of the movable block 22. Through the action of the curved surface 221, the old window frame compresses the movable block 22, causing it to move and stretch the first spring 23 until the old window frame abuts against the vertical wall of the movable block 22. The bottom frame 1 is then released, and through the contraction of the first spring 23, it pulls the bottom frame 1 so that the first frame plate 11 is tightly pressed against the old window frame. The first frame plate 11, together with the movable block 22, is clamped onto the old window frame, thus completing the auxiliary positioning of the bottom frame 1. After the bottom frame 1 is positioned, expansion screws are inserted into the wall from the second frame plate 12 to initially fix the bottom frame 1, the old window frame, and the wall. Then, screws are screwed into the window frame from one side of the first frame plate 11 to fix it again from the side.

[0041] The third frame plate 13 has a first sliding groove 131. A pad 24 is slidably installed on the third frame plate 13 through the first sliding groove 131. A second guide rod 27 is fixedly installed on the third frame plate 13. The second guide rod 27 passes through the pad 24 and is also slidably connected to the pad 24. A fixing plate 25 is fixedly installed on the pad 24. A support plate 26 is hinged on the third frame plate 13. A second sliding groove 261 is provided on the support plate 26. The second sliding groove 261 is a T-shaped groove. The fixing plate 25 extends into the second sliding groove 261 and is slidably connected to the support plate 26.

[0042] Screws are installed on the third frame plate 13. When the gap between the third frame plate 13 and the old window frame is small, there is no need to select the bottom frame 1 with the pad 24 and the support plate 26. When the gap between the third frame plate 13 and the old window frame is large, the screws pass through the pad 24. When the screws are tightened, the pad 24 will press and push the support plate 26 to move, so that the support plate 26 is pressed against the old window frame. At this time, the pad 24 pushes and presses the support plate 26 against the old window frame, and the support plate 26 can no longer rotate against the old window frame. Thus, the support plate 26 supports the third frame plate 13 and completes the fixation of the third frame plate 13. By using the support plate 26 to support the third frame plate 13, when the screws are tightened to fix the third frame plate 13, the deformation of the third frame plate 13 caused by the tension of the screws is reduced, and the deformation of the bottom frame 1 during the installation process is reduced, which may cause problems in the installation and use of the new window.

[0043] Reference Figure 4 , Figure 6 and Figure 7 The movable block 22 has a third sliding groove 222, which is a cross-shaped groove. A lifting plate 281 is slidably mounted on the movable block 22 through the third sliding groove 222, and the lifting plate 281 can slide up and down within the third sliding groove 222. A third guide rod 282 is fixedly mounted on one end of the lifting plate 281 near the pad 24. A telescopic sleeve 283 is slidably mounted on the third guide rod 282, and a second spring 284 is sleeved on the third guide rod 282. One end of the second spring 284 is fixedly connected to the telescopic sleeve 283, and the other end is fixedly connected to the lifting plate 281.

[0044] Before the bottom frame 1 is fitted onto the old window frame, the movable pad 24 is moved to the side of the telescopic sleeve 283 away from the lifting plate 281. The lifting plate 281 is moved so that the telescopic sleeve 283 abuts against the pad 24. The telescopic sleeve 283 abuts against the pad 24, causing the support plate 26 to move to a vertical position. This ensures that when the bottom frame 1 is fitted onto the old window frame, the old window frame can smoothly contact the arc surface 221 on the movable block 22. When the old window frame pushes the movable block 22 to move, the movable block 22 will also drive the lifting plate 281 to move and compress the second spring 284, increasing the pressure of the telescopic sleeve 283 on the pad 24 during the installation of the bottom frame 1, preventing the telescopic sleeve 283 from falling off the pad 24. After the old window frame passes the arc surface 221, the old window frame will push the lifting plate 281 to move vertically, causing the telescopic sleeve 283 to leave the pad 24, making the pad 24 and the support plate 26 movable.

[0045] The implementation principle of this embodiment is as follows: During installation, the bottom frame 1 is directly fitted onto the outside of the old window frame. The old frame is automatically guided along the arc surface 221 of the movable block 22, squeezing the movable block 22 and stretching the first spring 23 to complete the pre-positioning. The first spring 23 rebounds, causing the bottom frame 1 to automatically clamp the old frame, achieving rapid positioning. After being fitted into place, the old frame pushes the lifting plate 281, the telescopic sleeve 283 disengages from the pad 24, and the fixing screws are tightened. The pad 24 drives the support plate 26 to open and press against the old frame, forming a rigid support. The clamping plate 16 is quickly assembled through the interlocking structure, adapting to different window sills and functional requirements. The whole system achieves non-removal of the old frame, non-destructive installation, automatic positioning, self-adaptive fastening, and rapid construction, significantly improving the efficiency and installation quality of old window replacement.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
