Description

Technical Field

[0001] This invention relates to the field of door and window component technology, and in particular to an inward tilting and sliding door and window structure. Background Technology

[0002] Doors and windows are an important part of building design, serving to provide ventilation, lighting, heat insulation, and noise reduction.

[0003] To meet the need for micro-ventilation, existing technologies, such as the Chinese utility model patent with publication number CN203716773U, disclose an aluminum-plastic composite inward-tilting sliding door structure, including an external track and a bottom slide rail. The upper frame of the sliding door is connected to the external track by a pull rod, and the lower frame of the sliding door is set on the bottom slide rail. When the sliding door is closed, the pull rod is set in the external track. When the sliding door is opened, the pull rod supports the upper frame of the sliding door and tilts the sliding door. When the sliding door slides sideways, the sliding door drives the pull rod to slide on the external track. This door and window structure can achieve the effect of inward-tilting micro-ventilation, preventing outdoor wind from blowing directly on the human body and providing good protection for the people inside.

[0004] However, this aluminum-plastic composite inward-tilting sliding door structure relies solely on a pull rod to connect the external track and the upper frame of the sliding door. This results in poor structural stability, making it prone to significant wobbling during use. Furthermore, it lacks a corresponding locking device to secure the sliding door in the slightly ventilated and closed positions. Especially in the closed position, external forces (such as wind) can cause the sliding door to loosen, affecting its thermal insulation performance and generating noise, severely degrading the indoor living environment. Additionally, while one end of the pull rod slides along the external track and the other end rotates along the upper frame of the sliding door, this also makes the sliding door prone to loosening. It's difficult to align the sliding door with the ventilation opening on the door frame and then accurately push it into the sealed ventilation opening, thus reducing the user experience.

[0005] Therefore, it is necessary to improve the inward-tilting sliding door structure in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects in the prior art and provide an inward tilting and sliding door and window structure that improves structural stability to ensure heat insulation and sound absorption, improves the indoor living environment, and facilitates alignment operation to enhance the user experience.

[0007] To achieve the above technical effects, the technical solution of the present invention is: an inward tilting and sliding door / window structure, comprising: A window frame having closed openings and ventilation openings distributed along its own length; A fixed window is provided at the closed opening to close the closed opening; A movable window assembly includes a movable window unit, a telescopic unit, and a sliding member. The top and bottom of the movable window unit are connected to the sliding member via the telescopic unit to move the movable window unit to a closed position, a slightly ventilated position, and a fully ventilated position. In the closed position, the movable window unit is sealed to the vent. In the slightly ventilated position, the movable window unit is tilted and has a slight ventilation gap between its upper part and the vent. In the fully ventilated position, the movable window unit faces the plane where the vent is located and slides along the length of the window frame via the sliding member. A locking component is provided for locking the active window unit in a closed position.

[0008] Preferably, to facilitate the movement of the movable window unit, the telescopic units at the top and bottom of the movable window unit each include at least two telescopic mechanisms distributed along the sliding direction of the slider. The telescopic mechanism includes a first link and a second link. The two ends of the first link are respectively connected to the second link and the slider, and the two ends of the second link are respectively connected to the movable window unit and the slider.

[0009] Preferably, to facilitate opening the movable window unit, an assistive component is provided between one of the telescopic mechanisms and the sliding component, the assistive component being used to drive the movable window unit away from the plane where the vent is located.

[0010] Preferably, in order to enable the rotation of the movable window unit, at least one end of the telescopic mechanism is loosely engaged with the sliding member or the movable window unit.

[0011] Preferably, in order to ensure the stability of the rotation and movement of the movable window unit, the two ends of the telescopic mechanism are respectively rotatably connected to the sliding member and the movable window unit, and the relative rotation axis is parallel to the length direction of the window frame.

[0012] Preferably, in order to achieve locking of the movable window unit in the closed workstation, the locking assembly includes a handle, a transmission mechanism, a transmission rod, a sliding locking element, and a fixed locking element. The handle rotates on the movable window unit, the transmission mechanism is disposed inside the movable window unit, the transmission rod extends along the length direction parallel to the side wall of the movable window unit, the sliding locking element is fixedly connected to the transmission rod, and the handle is driven to move along the length direction parallel to the transmission rod via the transmission mechanism, so as to connect or separate the sliding locking element from the fixed locking element.

[0013] Preferably, to ensure the stability of the movable window unit in the micro-ventilation position, the telescopic mechanism is loosely fitted with the sliding member and / or the movable window unit. The inner bottom of the window frame is provided with a slot with an upward groove extending along the length of the window frame. The end of the slot adjacent to the fixed window is the inlet / outlet end. The inlet / outlet end is smoothly transitioned to the inner bottom wall of the window frame. The side of the slot that is away from the movable window unit is provided with a locking protrusion extending parallel to the length of the slot. The bottom of the movable window unit is connected to a pin by an elastic member so that the pin can move along the height direction of the movable window unit. The side of the bottom of the pin adjacent to the locking protrusion is the locking surface. When the movable window unit is in the micro-ventilation position, the locking surface abuts against the locking protrusion.

[0014] Preferably, to ensure the stability of the movable window unit in the micro-ventilation position and the closed position, the two ends of the telescopic mechanism are rotatably connected to the sliding member and the movable window unit, respectively. The fixing and locking member includes an upper locking sleeve fixed above the vent side, a lower locking sleeve disposed below the vent side, and an elastic rebound member connected between the lower locking sleeve and the window frame. The translation locking member includes an upper locking rod disposed at the top of the movable window unit and a lower locking rod disposed at the bottom of the movable window unit. The upper locking sleeve, the upper locking rod, the lower locking sleeve, and the lower locking rod all extend along the length direction parallel to the window frame. The upper locking rod and the lower locking rod are respectively inserted and engaged with the upper locking sleeve and the lower locking sleeve.

[0015] Preferably, in order to facilitate the accurate pushing of the movable window unit from the fully ventilated position to the closed position, a retractor is also provided on the window frame. The retractor is used to limit the movement path of the movable window unit in the fully ventilated position. One end of the movement path is a positioning end adjacent to the retractor. The movable window unit moves between the positioning end and the closed position through the telescopic mechanism.

[0016] Preferably, in order to facilitate and accurately guide the movable window unit from the fully ventilated position to the closed position, the retractor is provided with a guide groove, one end of which extends to the circumferential outer edge of the retractor, and the telescopic mechanism is connected with a guide block that slides with the guide groove.

This not only satisfies the different ventilation needs of the movable window unit in different positions, but also ensures structural stability, reduces shaking, guarantees thermal insulation performance and sound absorption, and helps to improve the indoor living environment.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] First Embodiment

[0021] like Figures 1-17 As shown, the inward tilting and sliding door / window structure of the first embodiment of the present invention includes: Window frame 1, which has a closed opening 11 and a vent 12 distributed along its own length; Fixed window 2 is installed at the closed opening 11 to close the closed opening 11; The movable window assembly includes a movable window unit 3, a telescopic unit 4, and a sliding member 5. The top and bottom of the movable window unit 3 are connected to the sliding member 5 through the telescopic unit 4 to move the movable window unit 3 to a closed position, a slightly ventilated position, and a fully ventilated position. In the closed position, the movable window unit 3 is sealed to the vent 12. In the slightly ventilated position, the movable window unit 3 is tilted and there is a slightly ventilated gap between the upper part and the vent 12. In the fully ventilated position, the movable window unit 3 is directly facing the plane where the vent 12 is located and slides along the length of the window frame 1 through the sliding member 5. Locking component 6 is used to lock the active window unit 3 in the closed position.

[0022] In this inward tilting and sliding door / window structure, the movable window unit 3 can be selected and controlled in different positions according to different user needs. Specifically, for example... Figure 1 As shown, this is the closed mode of the inward tilting and sliding door / window. In this mode, the telescopic units 4 at the top and bottom of the movable window unit 3 are retracted, so that the movable window unit 3 is in the closed position. The outer circumferential edge of the movable window unit 3 is sealed to the inner circumferential wall of the vent 12. At the same time, the locking component 6 is used to lock the movable window unit 3 in this position to ensure that the vent 12 is closed. In the absence of curtains, the movable window unit 3 and the fixed window 2 can still meet the lighting needs.

[0023] like Figure 2 As shown, this is the micro-ventilation mode of the inward tilting sliding door and window. In this mode, the telescopic unit 4 at the top of the movable window unit 3 extends towards the interior, while the telescopic unit 4 at the bottom retracts, so that the movable window unit 3 is in a micro-ventilation position and tilted. There is a micro-ventilation gap between its top and the vent 12, which can maintain ventilation on both the interior and exterior sides while preventing a large amount of wind from blowing into the interior side in a short period of time. In addition, when it rains, using the micro-ventilation mode can prevent external rainwater from falling into the interior while ensuring ventilation on both the interior and exterior sides.

[0024] like Figure 3 As shown, this is the full ventilation mode of the inward tilting and sliding window. In this mode, the telescopic units 4 at the top and bottom of the movable window unit 3 extend towards the interior, so that the movable window unit 3 maintains a certain gap with the ventilation opening 12, and the movable window unit 3 is in a vertical state. By moving the top and bottom sliding parts 5 along the length of the window frame 1, the portion of the movable window unit 3 that blocks the ventilation opening 12 is adjusted, and the air on the interior and exterior sides can circulate quickly through the unblocked portion of the ventilation opening 12.

[0025] The device allows for convenient adjustment of the position of the movable window unit 3 through the telescopic movement of the telescopic unit 4. The locking component 6 can securely lock the movable window unit 3 in the closed position, which can meet different ventilation needs. Compared with the method of using a pull rod to control the movable window unit 3, the structure is more stable and can effectively reduce the shaking of the movable window unit 3. This further ensures the thermal insulation and sound absorption capabilities of the door and window structure, reduces noise generation, and thus helps to improve the indoor living environment.

[0026] The specific structure of the window frame 1 and the fixed window 2 of the present invention is as follows: Figure 4 , Figure 6 and Figure 7 As shown, the window frame 1 includes a rectangular fixed frame 14. The length direction of the fixed frame 14 is horizontal and the width direction is vertical. Horizontal bars 15 extending along their own length direction are fixed on the inner top and inner bottom walls of the fixed frame 14. The ends and middle of the two horizontal bars 15 are fixedly connected by vertical bars 16 extending in the vertical direction. The two horizontal bars 15 and the three vertical bars 16 enclose and form a closed opening 11 and a ventilation opening 12. The fixed window 2 includes two first glass panes 21 arranged side by side along the thickness direction of the window frame 1. The circumferential outer edge of the first glass panes 21 is fixedly connected to the circumferential inner wall of the closed opening 11, thereby achieving the function of closing the closed opening 11 and allowing it to be used only for lighting. Both horizontal bars 15 are fixed with guide rails 17 extending along the length of the horizontal bars 15. The sliding member 5 is slidably connected to the guide rails 17. Specifically, the guide rail 17 at the bottom of the window frame 1 bears the weight of the movable window unit 3 and plays a guiding role, while the guide rail 17 at the top of the window frame 1 plays a guiding and limiting role to ensure the stable movement of the movable window unit 3. This satisfies the function of the movable window unit 3 being able to move along the length of the window frame 1 in the fully ventilated position, adjust the size of the ventilable area of ​​the vent 12, and thus regulate the ventilation volume.

[0027] The specific structure of the active window unit 3 is as follows: Figure 10 , Figures 12-16 As shown, the movable window unit 3 includes four profiles connected end to end to form a rectangular frame. The four profiles are two horizontal profiles 31 and two vertical profiles 32. An elastic sealing frame 34 is sealed to the inner side of the rectangular frame. Two second glass panes 33 are arranged along the thickness direction of the window frame 1 on the inner side of the sealing frame 34. First sealing strips 37 and second sealing strips 38 extending along their own length direction are provided on the outer side walls of the four profiles. The four first sealing strips 37 and the four second sealing strips 38 are connected end to end. Thus, the sealing frame 34, the first sealing strips 37 and the second sealing strips 38 are all made of elastic rubber. This ensures the airtightness of the connection between the movable window unit 3 and the ventilation opening 12 when it is in the closed position, thereby ensuring the thermal insulation performance of the door and window structure.

[0028] A further improvement is that the telescopic units 4 at the top and bottom of the movable window unit 3 each include at least two telescopic mechanisms 41 distributed along the sliding direction of the slider 5. The telescopic mechanism 41 includes a first link 411 and a second link 412. The two ends of the first link 411 are respectively connected to the second link 412 and the slider 5, and the two ends of the second link 412 are respectively connected to the movable window unit 3 and the slider 5.

[0029] In this embodiment, the telescopic units 4 at the top and bottom of the movable window unit 3 each include two telescopic mechanisms 41. The four telescopic mechanisms 41 work together on the movable window unit 3 to ensure the stable movement of the movable window unit 3 and to avoid damage and deformation due to an insufficient number of telescopic mechanisms 41. The telescopic mechanism 41 is a linkage structure composed of a first link 411 and a second link 412. The telescopic mechanism 41 achieves telescopic movement through the deformation of the linkage structure, thereby facilitating the movement and rotation of the movable window unit 3. Compared with a single pull rod, this linkage structure is easier to achieve telescopic deformation through the relative rotation of the first link 411 and the second link 412 to change the position of the movable window unit 3.

[0030] A further improvement is that an assisting element 42 is provided between one of the telescopic mechanisms 41 and the sliding element 5, which is used to drive the movable window unit 3 away from the plane where the vent 12 is located.

[0031] The specific structures of the telescopic unit 4 and the sliding member 5 are as follows: Figure 4 and Figure 5 As shown, the assisting components 42 are all assisting cylinders and their length direction is consistent with the length direction of the window frame 1. In the two telescopic mechanisms 41 of the telescopic unit 4, the length of the first connecting rod 411 is less than the length of the second connecting rod 412. At the top of the movable window unit 3, the sliding member 5 is long and narrow and is slidably connected to the top guide rail 17. The assisting component 42 is an assisting cylinder, and its cylinder is fixed on the sliding member 5. The piston rod is hinged to one end of the first connecting rod 411 in the right telescopic mechanism 41, and the other end of the first connecting rod 411 is hinged to the middle of the second connecting rod 412. One end of the second connecting rod 412 is hinged to the sliding member 5, and the other end is connected to the movable window unit 3. In the left telescopic mechanism 41, one end of the first connecting rod 411 is hinged to the sliding member 5, and the other end is provided with a strip-shaped opening 4111 extending along its own length direction. One end of the second connecting rod 412 is hinged to the sliding member 5, and the other end is connected to the movable window unit 3. A convex shaft 4121 is provided on the second connecting rod 412. The convex shaft 4121 passes through the inside of the strip-shaped opening 4111, and the outer diameter of the convex shaft 4121 is the same as the width of the strip-shaped opening 4111.

[0032] At the bottom of the movable window unit 3, the sliding member 5 includes a first slide bar 51, a sliding connecting rod 52, and a second slide bar 53, which are fixedly connected in sequence. The first slide bar 51 has a guide slide opening 511 at its end away from the second slide bar 53. The guide slide opening 511 includes a straight segment 5111 and an arc segment 5112 connected to each other. The straight segment 5111 connects to the end of the arc segment 5112 away from the second slide bar 53 and extends along a length direction parallel to the first slide bar 51. The end of the arc segment 5112 away from the straight segment 5111 protrudes towards the interior side. Both the first slide bar 51 and the second slide bar 53 slide on the guide rail 17 at the bottom of the window frame 1. The assisting member 42 is an assisting cylinder, whose cylinder is fixed to the second slide bar 53. The piston rod is connected to the right telescopic extension... In mechanism 41, one end of the first connecting rod 411 is hinged, and the other end of the first connecting rod 411 is hinged to the middle of the second connecting rod 412. One end of the second connecting rod 412 is hinged to the second slide bar 53, and the other end is connected to the movable window unit 3. In the left telescopic mechanism 41, one end of the first connecting rod 411 is hinged to the middle of the second connecting rod 412, and the other end is provided with a vertical shaft 4112. Both ends of the vertical shaft 4112 are provided with guide blocks 43. The outer diameter of the guide blocks 43 is larger than the outer diameter of the vertical shaft 4112. The outer diameter of the vertical shaft 4112 is consistent with the width of the guide slide 511 to cooperate with the sliding guide. The guide slide 511 fits between the two guide blocks 43. The two ends of the second connecting rod 412 are respectively connected to the first slide bar 51 and the movable window unit 3.

[0033] With the above structure, the first link 411 is pushed by the power cylinder to drive the first link 411 to rotate relative to the second link 412, which generates a force that pushes the movable window unit 3 toward the indoor side, so that the telescopic mechanism 41 tends to extend outward to the maximum extent, which makes it convenient for the movable window unit 3 to be pushed from the closed position to the micro-ventilation position or from the closed position to the full ventilation position.

[0034] A further improvement is that at least one end of the telescopic mechanism 41 is loosely fitted with the sliding member 5 or the movable window unit 3.

[0035] Specifically, in the telescopic mechanism 41, the second connecting rod 412 is loosely fitted with the movable window unit 3. A connecting shaft is fixed on the transverse profile 31 of the movable window unit 3. A through hole is provided at the end of the second connecting rod 412 away from the sliding member 5, and the connecting shaft passes through the inner side of the through hole. The outer diameter of the connecting shaft is larger than the outer diameter of the through hole. In this way, the connecting shaft and the transverse profile 31 are loosely fitted with the second connecting rod 412, thereby achieving a loose fit between the telescopic mechanism 41 and the movable window unit 3. This facilitates the rotation of the movable window unit 3. The main reason for this is that when the movable window unit 3 rotates at a small angle, only a loose fit can compensate for the rotational clearance caused by the rotation. Furthermore, the loose fit method reduces the dimensional requirements of the second connecting rod 412 and the connecting shaft, making assembly easier.

[0036] A further improvement is that the locking assembly 6 includes a handle 61, a actuator 62, a transmission rod 63, a translational locking member 64, and a fixed locking member 65. The handle 61 rotates on the movable window unit 3. The actuator 62 is disposed inside the movable window unit 3. The transmission rod 63 extends along the length direction parallel to the side wall of the movable window unit 3. The translational locking member 64 is fixedly connected to the transmission rod 63. The handle 61 is connected to the transmission rod 63 through the actuator 62 to drive the translational locking member 64 to move along the length direction parallel to the transmission rod 63, so that the translational locking member 64 is connected to or separated from the fixed locking member 65.

[0037] Specifically, such as Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 14 and Figure 15 As shown, the fixing and locking component 65 is an L-shaped folded plate structure, one part of which is fixed to the window frame 1, and the other part of which is perpendicular to the fixed plate. The handle 61 is connected to the housing 611, which is fixed to one of the vertical profiles 32. Each of the four profiles has an integrally formed slide rail on the side away from the second glass 33. A transmission rod 63 is slidably fitted in the slide rail. The length direction of the transmission rod 63 is consistent with the length direction of the corresponding profile. The transmission rods 63 corresponding to the two connected profiles are connected by a corner bracket 36. The transmission device 62 is set in the vertical profile 32 connected to the housing 611. The transmission device 62 includes a component fixed to the handle 61. The gear 621 is connected to two racks 622 on both sides of the gear 621. A connecting block 6221 is provided on the rack 622. The vertical profile 32 is provided with a vertical opening 321 communicating with its cavity on the side away from the second glass 33. The vertical opening 321 extends along the length direction parallel to the vertical profile 32. The connecting block 6221 is fixedly connected to the transmission rod 63 through the vertical opening 321 and slides inside the vertical opening 321. The translation locking member 64 is fixed on the side of the transmission rod 63 away from the second glass 33. Fixed locking members 65 are fixed on the inner walls of the four sides of the vent 12. The fixed locking members 65 correspond one-to-one with the translation locking members 64.

[0038] With the above structure, rotating the handle 61 causes the gear 621 to rotate, driving the rack 622 to move up and down. The rack 622 drives the transmission rod 63 to move via the connecting block 6221. The transmission rod 63 acts on other transmission rods 63 via the corner bracket 36, causing all transmission rods 63 to move simultaneously, thereby driving the translation locking member 64 to move. Based on the above, when the movable window unit 3 is facing the vent 12, rotating the handle 61 can change the position of the handle 61, such as... Figure 2 and Figure 3As shown, when the end of handle 61 is horizontal or upward, the sliding locking member 64 deviates from the fixed locking member 65, thus unlocking. At this time, the movable window unit 3 can be easily pushed from the micro-ventilation position or the full-ventilation position facing the vent 12 to the closed position, or pulled down from the closed position to the full-ventilation position or the micro-ventilation position towards the interior. When the end of handle 61 is vertically downward, the sliding locking member 64 abuts against the fixed locking member 65. The fixed locking member 65 is L-shaped, and the plate portion perpendicular to the fixed plate portion restricts the sliding locking member 64, thus locking. Figure 11 As shown, at this time, the outer edge of the movable window unit 3 is sealed to the inner wall of the vent 12, thereby realizing the function of locking the movable window unit 3 in the closed position.

[0039] A further improvement is that the telescopic mechanism 41 is loosely fitted with the movable window unit 3. The inner bottom of the window frame 1 is provided with a slot 13 with the groove facing upward and extending along the length of the window frame 1. The end of the slot 13 adjacent to the fixed window 2 is the inlet end 131. The inlet end 131 is smoothly transitioned to the inner bottom wall of the window frame 1. The side of the slot 13 away from the movable window unit 3 is provided with a locking protrusion 132 extending parallel to the length of the slot 13. The bottom of the movable window unit 3 is connected to a pin 72 by an elastic member 71 so that the pin 72 can move along the height direction of the movable window unit 3. The bottom of the pin 72 adjacent to the locking protrusion 132 is the locking surface 721. When the movable window unit 3 is in the micro-ventilation position, the locking surface 721 abuts against the locking protrusion 132.

[0040] Specifically, such as Figure 8 As shown, a notch is provided on the bottom horizontal bar 15, and a slot 13 is fixed inside the notch. The height of the slot 13 is the same as the depth of the notch, so that the opening of the slot 13 is flush with the top surface of the horizontal bar 15; Figure 16 and Figure 17 As shown, the transmission rod 63 at the bottom of the movable window unit 3 is equipped with a locking foot unit 7. The locking foot unit 7 includes a guide sleeve 73, a pin 72, and an elastic element 71. The guide sleeve 73 is fixed below the transmission rod 63. The guide sleeve 73 and the pin 72 form a telescopic cavity. The pin 72 slides on the guide sleeve 73 along the length of the movable window unit 3. The elastic element 71 is a spring that is located in the telescopic cavity and is in a compressed state. Its two ends are connected to the guide sleeve 73 and the pin 72, respectively. The side of the bottom of the pin 72 adjacent to the vent 12 is the locking surface 721. Furthermore, the slot 13 adjacent to the fixed window 2 has an inlet / outlet end 131 that smoothly transitions with the horizontal bar 15. Specifically, the inlet / outlet end 131 is inclined, which facilitates the pin 72 to slide smoothly into or out of the slot 13.

[0041] With the above structure, when the active window unit 3 is in such a state... Figure 1When in the closed position as shown, pin 72 is vertically positioned and located within slot 13. After rotating handle 61 upwards until its end is at a horizontal angle, pull the movable window unit 3 towards the interior side until... Figure 2 In the micro-ventilation position shown, the locking surface 721 of the pin 72 abuts against the locking protrusion 132 of the slot 13, and the spring is compressed into the telescopic cavity for limiting. At the same time, the telescopic unit 4 at the top of the movable window unit 3 extends to the indoor side to the maximum extent. In this way, the telescopic unit 4 at the bottom of the movable window unit 3 can be prevented from extending, and the movable window unit 3 can lock its position by its own weight in conjunction with the telescopic unit 4 at the top, preventing the movable window unit 3 from loosening. In this way, the stability of the position structure of the movable window unit 3 is ensured in the micro-ventilation position, avoiding vibration and noise, and ensuring the micro-ventilation requirement.

[0042] A further improvement is that a retractor 8 is also provided on the window frame 1. The retractor 8 is used to limit the movement path of the movable window unit 3 in the fully ventilated position. One end of the movement path is the positioning end adjacent to the retractor 8. The movable window unit 3 moves between the positioning end and the closed position through the telescopic mechanism 41. A guide groove 81 is provided on the retractor 8. One end of the guide groove 81 extends to the circumferential outer edge of the retractor 8. The telescopic mechanism 41 is connected to a guide block 43 that slides with the guide groove 81.

[0043] Specifically, such as Figure 5-Figure 5 (B) Figure 8 and Figure 9 As shown, the receiver 8 includes a horizontal U-shaped plate 82. The upper and lower side walls 821 of the U-shaped plate 82 are fixedly connected by a vertical plate 83 to make the receiver 8 a closed-loop structure. The receiver 8 is fixed to the inner side of the guide rail 17 at the bottom of the window frame 1. Guide grooves 81 are provided on both the upper and lower side walls of the receiver 8. The two guide grooves 81 correspond one-to-one with the guide blocks 43 at both ends of the vertical shaft and slide in fit. The extension direction of the guide grooves 81 has an angle with both the length direction and the thickness direction of the window frame 1. The end of the first slide bar 51 away from the second slide bar 53 is integrally formed with a positioning part for passing through the inner side of the receiver 8. The guide slide opening 511 is provided on the positioning part.

[0044] With the above structure, the movable window unit 3 moves in the fully ventilated position via the sliding guide rail 17 and the sliding member 5. When it is necessary to adjust the movable window unit 3 to the closed position to close the vent 12, the movable window unit 3 is moved towards the positioning end. During the movement, the positioning part first passes through the inside of the receiver 8, so that the vertical shaft at the guide slide 511 of the positioning part enters the inside of the receiver 8. The vertical shaft drives the guide blocks 43 at both ends to enter the guide groove 81. When the guide block 43 and the end of the guide groove 81 away from the outer edge of the receiver 8 come into contact, the first link 411 and the second link 412 in the telescopic mechanism 41 rotate relative to each other, and the overall length of the telescopic mechanism 41 decreases, so that the movable window unit 3 is pushed from the fully ventilated position to the closed position, thus completing the closing operation of the vent 12. When in use, there is no need to deliberately align the movable window unit 3 with the vent 12. Simply slide it along the length of the window frame 1. Under the guidance of the retractor 8, the movable window unit 3 can be smoothly pushed from the fully ventilated position to the closed position through the cooperation of the guide block 43 and the guide groove 81. It is convenient and quick to use, and improves the user experience.

[0045] In order to protect the telescopic unit 4 from external squeezing and collision damage, and to ensure the aesthetics of the movable window unit 3, a cover 35 is fixed on both horizontal profiles 31. The cover 35 is used to shield and protect the telescopic unit 4 to ensure its normal operation.

[0046] Second Embodiment

[0047] like Figures 18-27 As shown, the inward tilting and sliding door and window structure of the second embodiment of the present invention is based on the first embodiment, except that the two ends of the telescopic mechanism 41 are rotatably connected to the sliding member 5 and the movable window unit 3 respectively, and the relative rotation axis is parallel to the length direction of the window frame 1.

[0048] Compared to the loosely fitted telescopic mechanism 41 in the first embodiment, the telescopic mechanism 41 in this embodiment rotates between the movable window unit 3 and the sliding member 5. Therefore, the structure is more stable, which can effectively reduce the loosening of the movable window unit 3 and ensure the sealed connection between the movable window unit 3 and the vent 12 in the closed position. This ensures the good sealing performance of the door and window structure, enhances the heat insulation performance, avoids noise caused by vibration, and improves the indoor living environment.

[0049] The window frame 1 in this embodiment includes a rectangular fixed frame 14. The fixed frame 14 includes a bottom strip 141 extending in the horizontal direction. A top strip 142 is provided directly above the bottom strip 141, which is in the same direction as its length. The ends of the bottom strip 141 and the top strip 142 are fixedly connected by a support column 143. Two rectangular frames 18 connected in the length direction are fixed inside the fixed frame 14. The openings of the two rectangular frames 18 are respectively formed into a ventilation opening 12 and a closed opening 11.

[0050] To enable the telescopic mechanism 41 to rotate between the movable window unit 3 and the sliding member 5, in this embodiment, the specific structure of the movable window assembly is as follows: Figures 24-27 As shown, at the top of the movable window unit 3, the sliding member 5 is long and narrow. A first circular shaft 54 ​​extending along its own length is integrally formed on the sliding member 5. In the telescopic mechanism 41, the ends of the first connecting rod 411 and the second connecting rod 412 away from the movable window unit 3 are both hinged to a sliding connecting strip 414. A rotating strip 415 is fixed to the sliding connecting strip 414. The rotating strip 415 rotates around the axis of the first circular shaft 54 ​​outside the first circular shaft 54.

[0051] At the bottom of the movable window unit 3, a horizontal shaft 39 extending along its length is fixedly connected to the bottom of the horizontal profile 31. A door and window connecting strip 413 is fitted and rotated around the horizontal shaft 39. One end of the second connecting rod 412 is hinged to the door and window connecting strip 413. A rotating strip 415 extending along its length is fixedly connected to the first sliding strip 51. A sliding member 5 extending along the length of the guide rail 17 slides on the guide rail 17 at the bottom of the window frame 1. A second circular shaft 55 extending along its length is integrally formed on the sliding member 5. The rotating strip 415 rotates around the axis of the second circular shaft 55 and is fitted around the second circular shaft 55. In this way, the telescopic mechanism 41 can rotate relative to the movable window unit 3 and the window frame 1, which facilitates the rotation of the movable window unit 3 during the switching between the micro-ventilation position and the closed position.

[0052] In order to support the smooth sliding of the movable window unit 3, the bottom surface of the sliding member 5 at the bottom of the movable window unit 3 is also provided with rollers 44 distributed at intervals along the length of the window frame 1. The rollers 44 support the sliding member 5 to reduce the force on the telescopic component at the high position and facilitate the lateral sliding of the movable window unit 3.

[0053] Furthermore, unlike the first embodiment, the locking component 6 can lock the movable window unit 3 in a slightly ventilated position and a closed position. The fixing locking component 65 includes an upper locking sleeve 651 fixed above the vent 12 side, a lower locking sleeve 652 disposed below the vent 12 side, and a spring-loaded component 653 connected between the lower locking sleeve 652 and the window frame 1. The translation locking component 64 includes an upper locking rod 641 disposed at the top of the movable window unit 3 and a lower locking rod 642 disposed at the bottom of the movable window unit 3. The upper locking sleeve 651, upper locking rod 641, lower locking sleeve 652 and lower locking rod 642 all extend along the length direction parallel to the window frame 1. The upper locking rod 641 and lower locking rod 642 are respectively inserted into the upper locking sleeve 651 and lower locking sleeve 652.

[0054] Specifically, such as Figures 21-24 and Figure 27As shown, in the locking assembly 6, the upper locking sleeve 651 is fixed below the top bar 142, and a U-shaped frame 655 is fixed on the bottom bar 141. The two ends of the opening of the U-shaped frame 655 are fixedly connected by a fixed shaft 654. The two ends of the fixed shaft 654 are fitted with spring-loaded members 653, which are torsion springs. A lower locking sleeve 652 is provided between the two torsion springs. The two ends of the torsion springs are connected to the lower locking sleeve 652 and the U-shaped frame 655 respectively. The torsion springs drive the lower locking sleeve 652 to rotate upward about the axis of the fixed shaft 654. A positioning plate 656 is also provided on the U-shaped frame 655. One end of the positioning plate 656 is used to abut against the lower locking sleeve 652 to position the rotation angle of the lower locking sleeve 652.

[0055] In addition, the transmission rods 63 in the locking assembly 6 slide within the cavities of their respective profiles. The side of the transverse profile 31 away from the second glass 33 is provided with a transverse opening 311 that communicates with its own cavity and extends along the length of the window frame 1. A transverse slider 66 slides inside the transverse opening 311. The transverse slider 66 is fixedly connected to the transmission rods 63 in the transverse profile 31. An upper locking rod 641 is fixed on the transverse slider 66 above the movable window unit 3, and a lower locking rod 642 is fixed on the transverse slider 66 below the movable window unit 3.

[0056] With the above structure, in the initial state of the device, the movable window unit 3 is in the closed position, the handle 61 is set vertically downward, the upper locking rod 641 passes through the inner side of the upper locking sleeve 651, and the lower locking rod 642 passes through the inner side of the lower locking sleeve 652, thereby locking the movable window unit 3 in the closed position.

[0057] After rotating handle 61 upwards by 90°, the upper locking rod 641 disengages from the upper locking sleeve 651, while the lower locking rod 642 remains inside the lower locking sleeve 652. At this time, the upper part of the movable window unit 3 is movable, while the lower part has a limited range of motion and can only be rotated slightly by the spring-loaded member 653. Therefore, under the action of the top assist member 42 of the movable window unit 3, the top telescopic mechanism 41 unfolds, which can tilt and rotate the movable window unit 3 towards the indoor side and disengage the upper part from the vent 12.

[0058] If the handle 61 is rotated upward by 90°, the lower locking rod 642 will disengage from the inner side of the lower locking sleeve 652. Under the action of the lower assist component 42 of the movable window unit 3, the bottom telescopic mechanism 41 will unfold, thereby pushing the movable window unit 3 to the indoor side to the fully ventilated position.

[0059] In the fully ventilated position, the movable window unit 3 can slide along the guide rail 17. When the telescopic mechanism 41 at the bottom of the movable window unit 3 abuts against the retractor 8, keep the handle 61 vertically upward and push the movable window unit 3 to the outside side to push the movable window unit 3 to the closed position, blocking the vent 12. Then, select the handle 61 half a turn so that the upper locking rod 641 is inserted into the upper locking sleeve 651 and the lower locking rod 642 is inserted into the lower locking sleeve 652, thus locking the movable window unit 3 in the closed position.

[0060] Third Embodiment

[0061] like Figures 28-30 As shown, the inward tilting and sliding door and window structure of the third embodiment of the present invention is based on the second embodiment, except that the telescopic mechanism 41 at the top of the movable window unit 3 is connected to a fastening component 9. The fastening component 9 is used to lock the second connecting rod 412 of the telescopic mechanism 41 at multiple rotation angle positions to adjust the tilt angle of the movable window unit 3 and the micro-ventilation gap between the upper part of the movable window unit 3 and the vent 12 in the micro-ventilation position, thereby realizing the adjustment of the micro-ventilation volume.

[0062] In this device, the rotation angle of the second link 412 can be locked by the fastening component 9, thereby locking the rotation angle of the first link 411. Therefore, by locking the rotation angles of the first link 411 and the second link 412, the extension and retraction amount of the telescopic mechanism 41 is locked, thereby locking the tilt angle of the movable window unit 3, which can adjust the ventilation volume according to the wind conditions of the external environment and its own ventilation needs.

[0063] Specifically, the end of the second link 412 away from the sliding member 5 is fixed with a drive gear 91, the drive gear 91 meshes with a transmission gear 92, and the transmission gear 92 is fixedly connected to a driven gear 93 along the coaxial line. Both the driven gear 93 and the transmission gear 92 rotate around their own axis on the top surface of the top horizontal profile 31 of the movable window unit 3.

[0064] A fastening strip 94 is provided on one side of the driven gear 93. Several protruding teeth 941 are provided on the side of the fastening strip 94 adjacent to the driven gear 93. The protruding teeth 941 are adapted to the driven gear 93. A fixing plate 97 is connected to the other side of the fastening strip 94 through a compression spring 95. The fixing plate 97 is fixed on the transverse profile 31. A guide rod 96 is also fixedly connected to the fastening strip 94 and slides through the fixing plate 97. A limit plate 961 is provided at the end of the guide rod 96 away from the fastening strip 94.

[0065] To facilitate control of the extension and retraction of the fastening strip 94, the fastening strip 94 is made of magnetic material. Electromagnets 98 are provided on both ends of the fixing plate 97 adjacent to the fastening strip 94. A button 612 is provided on the handle 61. The button 612 is used to control the energization and de-energization of the electromagnet 98, so as to control the fastening strip 94 to move closer to or away from the driven gear 93.

[0066] With the above structure, pressing button 612 energizes electromagnet 98, attracting fastening bar 94 to slide. Through the cooperating groove and slider structure, it can limit the driven gear 93. Specifically, the fastening bar 94 overcomes the elastic force of compression spring 95 and moves away from the driven gear 93, causing the protrusion 941 on the fastening bar 94 to disengage from the driven gear 93, thereby facilitating the rotation of the second link 412 and the driving gear 91, thus facilitating the extension and retraction of the telescopic mechanism 41 to control the rotation of the movable window unit 3. After releasing button 612, electromagnet 98 is de-energized, and the pressure... Under the elastic force of spring 95, fastening bar 94 moves towards driven gear 93, thereby causing convex tooth 941 to abut against driven gear 93, fixing the rotation angle of driven gear 93, and locking the rotation angle of second link 412, so that the extension and retraction amount of telescopic mechanism 41 is fixed, thereby locking the tilt angle of movable window unit 3, and fixing the micro ventilation gap between the upper part of movable window unit 3 and vent 12. In this way, users can choose to lock movable window unit 3 at different tilt angles according to their own ventilation needs to adjust the ventilation volume, further improving the user experience.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
