Description

Technical Field

[0001] This utility model relates to a replacement structure, and more particularly to a replacement structure for smart doors and windows, belonging to the field of smart door and window technology. Background Technology

[0002] As an important component of smart homes, smart doors and windows rely primarily on window pushers for their automated opening and closing functions. These pushers drive the window sashes through a mechanism, enabling intelligent operations such as remote control and weather sensing. They are widely used in residential, office, and commercial buildings.

[0003] In existing intelligent window and door pusher installation structures, the main body of the pusher is mostly fixed to the window frame using bolt connections: mounting holes are pre-drilled in the window frame, and bolts passing through the pusher mounting base are locked to the window frame threads to achieve rigid fixation. Although this fixing method can ensure connection strength, it has significant drawbacks: disassembly and assembly require tools such as screwdrivers and wrenches, making the operation cumbersome and time-consuming; repeated disassembly and assembly can easily lead to wear of the screw holes in the window frame, reducing connection reliability and even damaging the structural integrity of the window frame; for installation at heights or in narrow spaces, tool operation is restricted, further increasing the difficulty of installation and maintenance.

[0004] To address this issue, a smart door and window replacement structure was designed. Utility Model Content

[0005] The main purpose of this utility model is to provide a replacement structure for intelligent doors and windows to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A replacement structure for a smart door and window includes a window frame, a window sash hinged to the window frame, a window pusher for opening and closing the window sash, a sliding plate rotatably mounted on the window pusher, and a positioning hole at the end of the sliding plate.

[0008] The top of the window sash has a guide groove along its length, and a positioning mechanism that is slidably connected to the end of the push-pull plate is installed inside the guide groove.

[0009] The top inner edge of the window frame is provided with a mounting groove for installing the window pusher. One end of the window pusher is fixed with a fixing plate, and the end of the mounting groove is provided with a first insertion hole that mates with the fixing plate.

[0010] The end of the window pusher away from the fixed plate is equipped with a plug-in mechanism for plugging the window pusher into the window frame.

[0011] Preferably, the positioning mechanism includes a slider, a limiting hole, a pressure plate, a plug rod, and a tension spring. The slider is slidably disposed inside the guide groove. A limiting hole that mates with the positioning hole is opened on the top of the slider. A pressure plate is hinged to the top of the slider. A plug rod that mates with the limiting hole is fixed to the end of the pressure plate. A tension spring is fixedly installed between the inner side of the pressure plate and the slider.

[0012] Preferably, the pressure plate is shaped like an inverted "6", the insertion rod is perpendicular to the horizontal plane when inserted, and the thickness of the protrusion of the pressure plate is greater than the thickness of the push-pull plate.

[0013] Preferably, the fixing plate is semi-circular in shape, and the diameter of the fixing plate is the same as the length of the first insertion hole.

[0014] Preferably, the insertion mechanism includes a slide groove, a trapezoidal plug, a return spring, a second insertion hole, and an unlocking component. The slide groove is located at the end of the window pusher away from the fixed plate. The trapezoidal plug is slidably disposed inside the slide groove. A return spring is provided between the trapezoidal plug and the inner end of the slide groove. The end of the mounting groove away from the first insertion hole is provided with a second insertion hole that mates with the trapezoidal plug. The bottom end of the window pusher is provided with an unlocking component that controls the sliding of the trapezoidal plug.

[0015] Preferably, the unlocking component includes a strip groove and a pull block. The strip groove is opened at the bottom end of the slide groove, and the pull block, which is fixedly connected to the trapezoidal insert, is slidably disposed inside the strip groove.

[0016] Preferably, the bottom of the pull block is arc-shaped, and the bottom of the pull block is provided with anti-slip texture.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves tool-free quick assembly and disassembly of the window pusher and window frame, and the sliding plate and window sash slider through the coordinated design of the positioning mechanism and the insertion mechanism. In the positioning mechanism, the cooperation between the plug rod and the tension spring can achieve the insertion and locking of the limiting hole by manual pulling, without the need for tools such as screwdrivers. The trapezoidal plug of the insertion mechanism automatically engages under the action of the return spring, and can be separated by the pull block. This solves the problem of traditional bolt connection requiring tools and being cumbersome and time-consuming, and is especially suitable for high-altitude or narrow space operations.

[0019] 2. This utility model abandons the traditional rigid connection method of bolts passing through the window frame. By using the insertion and positioning of the first insertion hole and the fixing plate, and the flexible snap-fit ​​of the trapezoidal insertion block and the second insertion hole, it avoids wear or cracking of the screw holes in the window frame caused by repeated disassembly and assembly, reduces damage to the original door and window structure, and improves the overall stability.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a replacement structure for intelligent doors and windows, including a window frame 1, a window sash 101 hinged to the window frame 1, a window pusher 103 that drives the window sash 101 to open and close, a sliding plate 104 rotatably mounted on the window pusher 103, and a positioning hole 105 opened at the end of the sliding plate 104.

[0036] The top of the window sash 101 is provided with a guide groove 102 along the length direction. The guide groove 102 has a 'U' shaped cross section, an opening width of 20mm, a depth of 15mm, and symmetrical flanges with a height of 1mm on both inner walls. The guide groove 102 is slidably provided with a positioning mechanism 2 connected to the end of the push-pull plate 104.

[0037] The top inner part of the window frame 1 is provided with a mounting groove 106 for installing the window pusher 103;

[0038] The mounting groove 106 is 30mm wide and 25mm deep. The main body of the window pusher 103 is 29.5mm wide and has a clearance of 0.5-1mm between it and the mounting groove 106.

[0039] One end of the window pusher 103 is fixed with a fixing plate 3, and the end of the mounting groove 106 is provided with a first insertion hole 301 that mates with the fixing plate 3;

[0040] The fixing plate 3 has a diameter of 15mm and the first insertion hole 301 has a length of 15mm. It adopts a transition fit (maximum clearance 0.018mm) to ensure that the axial positioning accuracy of the window pusher 103 is ≤0.1mm.

[0041] The end of the window pusher 103 away from the fixed plate 3 is provided with a plug-in mechanism 4, which is used to plug the window pusher 103 into the window frame 1.

[0042] The replacement structure of this intelligent door and window achieves quick connection between the pusher 103 and the window frame 1, and between the sliding plate 104 and the window sash 101 through modular design. The inner top of the window frame 1 has an installation groove 106 to accommodate the pusher 103. The fixing plate 3 at one end of the pusher 103 is inserted into the first insertion hole 301 at the end of the installation groove 106 to achieve initial positioning. The insertion mechanism 4 at the other end of the pusher 103 securely connects it to the window frame 1 to prevent loosening. The guide groove 102 at the top of the window sash 101 provides a sliding track for the positioning mechanism 2. The positioning mechanism 2 and the end of the sliding plate 104 cooperate through the positioning hole 105 to realize the linkage between the sliding plate 104 and the window sash 101. When the pusher 103 is working, it drives the sliding plate 104 to rotate. The sliding plate 104 drives the window sash 101 to rotate along the hinge of the window frame 1 through the positioning mechanism 2 to complete the opening and closing action.

[0043] Example 2

[0044] The solution in Example 1 will be further described below with reference to its specific working method.

[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, the positioning mechanism 2 further includes a slider 201, a limiting hole 202, a pressure plate 203, an insert rod 204, and a tension spring 205. The slider 201 is slidably disposed inside the guide groove 102. The slider 201 is made of PA66+30% glass fiber, with a width of 19.8mm. The bottom is provided with a groove (1.2mm deep) that mates with the flange inside the guide groove 102, with a fitting clearance of 0.1-0.2mm to ensure smooth sliding and no axial movement.

[0046] The top of the slider 201 is provided with a limiting hole 202 that mates with the positioning hole 105. A pressure plate 203 is hinged to the top of the slider 201. A plug rod 204 that is inserted into the limiting hole 202 is fixed to the end of the pressure plate 203. A tension spring 205 is fixedly installed between the inner side of the pressure plate 203 and the slider 201.

[0047] When the push-pull plate 104 is connected to the window sash 101, after the limiting hole 202 at the top of the slider 201 is aligned with the positioning hole 105 at the end of the push-pull plate 104, the insertion rod 204 at the end of the pressure plate 203 is inserted into the limiting hole 202 and the positioning hole 105 under the pulling force of the tension spring 205, thereby locking the push-pull plate 104 and the slider 201.

[0048] like Figure 4 As shown, in a preferred embodiment, based on the above method, the pressure plate 203 is further shaped like an inverted "6", the insertion rod 204 is perpendicular to the horizontal plane when inserted, and the thickness of the protrusion of the pressure plate 203 is greater than the thickness of the push-pull plate 104.

[0049] After the push-pull plate 104 is positioned, there is a certain angle between the pressure plate 203 and the top of the slider 201, which applies greater pressure to the push-pull plate 104. Meanwhile, the insertion rod 204 is in a vertical state. When subjected to the pulling and pushing forces of the push-pull plate 104, no force is generated in other directions, ensuring the stability of the position of the push-pull plate 104. During disassembly, the pressure plate 203 is manually moved away from the slider 201, the tension spring 205 is stretched, and the insertion rod 204 is pulled out from the limiting hole 202 and the positioning hole 105, thus separating the push-pull plate 104 and the slider 201 without tools.

[0050] like Figure 3 As shown, in a preferred embodiment, based on the above method, the fixing plate 3 is further shaped as a semi-circle, and the diameter of the fixing plate 3 is the same as the length of the first insertion hole 301. When the window pusher 103 is installed, the semi-circular fixing plate 3 can avoid causing wear on the inner wall of the mounting groove 106.

[0051] like Figure 3 As shown, in a preferred embodiment, based on the above method, the insertion mechanism 4 further includes a slide groove 401, a trapezoidal plug 402, a return spring 403, a second insertion hole 406, and an unlocking component. The slide groove 401 is opened at one end of the window pusher 103 away from the fixed plate 3. The trapezoidal plug 402 is slidably disposed inside the slide groove 401. A return spring 403 is provided between the trapezoidal plug 402 and the inner end of the slide groove 401. A second insertion hole 406 that cooperates with the trapezoidal plug 402 is opened at one end of the mounting groove 106 away from the first insertion hole 301. An unlocking component for controlling the sliding of the trapezoidal plug 402 is provided at the bottom end of the window pusher 103.

[0052] When the window pusher 103 is installed, the fixing plate 3 is first inserted into the first insertion hole 301, and then the other end of the window pusher 103 is pressed upward. The inclined side of the trapezoidal insert 402 first contacts the end face of the mounting groove 106. The trapezoidal inclined surface angle of the trapezoidal insert 402 is 35°, the insertion end length is 18mm, and the root width is 10mm. As the pressing force increases, the trapezoidal insert 402 is pressed into the sliding groove 401. After the window pusher 103 is completely inserted into the mounting groove 106, the trapezoidal insert 402 slides out along the sliding groove 401 under the pushing force of the return spring 403 and inserts into the second insertion hole 406 at the corresponding position of the window frame 1, so as to realize the snap-fit ​​fixation between the window pusher 103 and the window frame 1.

[0053] like Figure 3 As shown, in a preferred embodiment, based on the above method, the unlocking component further includes a strip groove 404 and a pull block 405. The strip groove 404 is opened at the bottom end of the slide groove 401, and the pull block 405, which is fixedly connected to the trapezoidal insert 402, is slidably disposed inside the strip groove 404.

[0054] When disassembling the window pusher 103, pull the pull block 405 in the strip groove 404. The pull block 405 drives the trapezoidal insert 402 to compress the return spring 403 and retract into the slide groove 401. The trapezoidal insert 402 separates from the second insertion hole 406, and the window pusher 103 can be taken out from the mounting groove 106.

[0055] like Figure 3 As shown, in a preferred embodiment, based on the above method, the bottom end of the pull block 405 is arc-shaped, and the bottom of the pull block 405 is provided with anti-slip texture. The arc-shaped design and anti-slip texture at the bottom end of the pull block 405 can improve the ease of operation.

[0056] Example 3

[0057] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0058] During installation, insert the fixing plate 3 at one end of the window pusher 103 into the first insertion hole 301 of the mounting groove 106, and at the same time push the window pusher 103 so that the trapezoidal insertion block 402 at the other end is aligned with the second insertion hole 406. The trapezoidal insertion block 402 automatically snaps into the second insertion hole 406 under the action of the return spring 403, thus completing the fixing of the window pusher 103. Then, slide the slider 201 to the appropriate position, align the positioning hole 105 at the end of the push-pull plate 104 with the limiting hole 202 of the slider 201, release the lever 203, and the insertion rod 204 is inserted into the two holes under the action of the tension spring 205, thus completing the connection.

[0059] During disassembly, move the pressure plate 203 to disengage the insertion rod 204 from the limiting hole 202 and the positioning hole 105, push the push-pull plate 104 to separate it, pull the pull block 405 to disengage the trapezoidal insertion block 402 from the second insertion hole 406, move the window pusher 103 away from the first insertion hole 301, disengage the fixing plate 3 from the first insertion hole 301, and then remove the window pusher 103;

[0060] The entire process requires no tools, avoiding the drawbacks of traditional bolted connections and improving maintenance efficiency.

[0061] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
