Description

Technical Field

[0001] This invention relates to the field of door and window accessories technology, specifically to a pull rod device and door and window system with an adjustable inward tilting angle. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] A tilt-and-turn window can be switched to three different states by turning the door and window handle, which activates the internal hardware mechanism of the door and window, allowing the door and window to be locked (handle pointing vertically downwards), open (handle pointing horizontally), or tilted inwards (handle pointing vertically upwards).

[0004] Currently, none of the tilt-and-turn windows on the market can adjust their tilt-and-turn angle, which brings several obvious disadvantages: First, a fixed tilt-and-turn angle means that the size of the ventilation opening cannot be adjusted, and users cannot flexibly adjust the ventilation volume according to the weather or indoor needs, resulting in limited ventilation efficiency; Second, when the tilt-and-turn angle is too large, rainwater may more easily enter the room on rainy days; when the tilt-and-turn angle is too small, the ventilation effect may be insufficient, making it difficult to balance rain protection and ventilation needs, thus limiting the usage scenarios; Third, a fixed tilt-and-turn angle makes it difficult to match window sash profiles of different thicknesses. For thicker window sash profiles, it may result in an inward tilt-and-turn opening that is too small, while for thinner window sash profiles, it may result in an inward tilt-and-turn opening that is too large, resulting in poor adaptability. Summary of the Invention

[0005] In order to overcome the defects of the prior art, the present invention provides a pull rod device and a door and window system with an adjustable inward tilting angle. The pull rod device can adjust the maximum rotation opening angle of the long rotating rod, thereby adjusting the inward tilting angle of the pull rod device and solving the problems mentioned in the background art.

[0006] The technical solution adopted by this invention to solve its problem is: A pull rod device with an adjustable inward tilting angle, which is disposed on a door or window and connects the door / window frame and the door / window sash respectively, includes: The pull rod seat is fixed to the door or window sash and has a sliding groove inside; A pull rod is disposed within the slide groove; the pull rod extends along the extension direction of the slide groove. A long rotating rod, one end of which is pivotally connected to the pull rod and the pivot point can move along the extension direction of the slide groove, and the other end of which is pivotally connected to the door and window frame; A limiting seat is provided in the slide groove; the pull rod is provided with a retaining seat for cooperating with the limiting seat, the limiting seat and / or the retaining seat are adjustable structures and can move along the extension direction of the slide groove to adjust their positions; When the window is tilted inward, the long rotating rod drives the pull rod to move along one side of the sliding groove, which in turn drives the card seat to move until the card seat abuts or engages with the limiting seat. At this point, the card seat is limited and the long rotating rod rotates to open to the maximum angle.

[0007] As an optional implementation, the card holder and the limiting seat are engaged by a snap-fit ​​structure. The snap-fit ​​structure includes a snap-fit ​​block and a snap-fit ​​groove. One of the snap-fit ​​block and the snap-fit ​​groove is disposed on the card holder, and the other is disposed on the limiting seat.

[0008] As an optional implementation, the card slot includes a buffer slide and a fastening groove communicating with the buffer slide, and the card block includes a body and a card head disposed on the body. When the card holder is moved until the card head of the card block extends into the buffer groove, the card holder can be buffered. Then the card holder continues to move until the card head is engaged and fixed with the fastening groove, at which point the card holder is limited.

[0009] As an optional implementation, the card holder or the limiting seat is provided with two spring buckles arranged at intervals, and the card slot is defined between the two spring buckles and the card holder, or between the two spring buckles and the limiting seat; When the card head of the card block extends into the buffer groove, the two spring buckles undergo elastic deformation and are stretched open to buffer the card seat.

[0010] As an optional implementation, the outer wall of the pull rod is provided with an external thread, and the card holder is provided with a threaded hole adapted to the external thread. The card holder is threadedly connected to the external thread on the pull rod through the threaded hole. When the pull rod is rotated, the card holder can be moved along the extension direction of the pull rod to adjust its position.

[0011] As an optional implementation, an adjustment hole is provided at one end of the pull rod.

[0012] As an optional implementation, the two outer side walls of the card holder are respectively fitted with the two inner side walls of the slide groove to achieve guidance.

[0013] As an optional implementation, it also includes a slide block disposed at the other end of the pull rod and slidably disposed in the slide groove, with one end of the long rotating rod pivotally connected to the slide block.

[0014] As an optional implementation, it also includes a short rotating rod, one end of which is pivotally connected to the pull rod seat, and the other end of which is pivotally connected to the long rotating rod; When the window tilts inward, the long rotating rod, the short rotating rod, and the pull rod seat form a triangular structure.

[0015] In addition, the present invention also provides a door and window system, including a door and window frame, a door and window sash, and the aforementioned tie rod device, wherein: The tie rod seat is fixedly mounted on the door / window sash; An upper mounting plate is fixedly installed inside the door and window frame, and the other end of the long rotating rod is pivotally connected to the upper mounting plate.

[0016] In summary, the adjustable inward tilting angle tie rod device and door / window system provided by the present invention have the following beneficial effects: (1) The pull rod device of the present invention can adjust the maximum rotation opening angle of the long rotating rod by adjusting the position of the limiting seat and / or the card seat in the slide groove, thereby realizing the adjustment of the inward tilting opening angle of the pull rod device. Therefore, by using the pull rod device of the present application, the user can adjust the inward tilting opening angle of the door and window sash according to actual needs, thereby ensuring the ventilation efficiency of the door and window sash, adapting it to different usage scenarios, and being able to adapt to door and window profiles of different thicknesses, which is highly practical.

[0017] (2) The pull rod device of the present invention has a locking structure between its card seat and the limiting seat to achieve a locking engagement. The locking structure can limit and fix the door and window sash after it tilts inward, thereby improving the stability of the door and window sash after it tilts inward. In addition, the card groove includes a buffer slide groove. When the card head of the card block is inserted into the buffer slide groove, the door and window sash can be buffered to avoid damage to the pull rod device due to excessive force when the door and window sash tilts inward.

[0020] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] See Figure 1-5 This invention provides a pull rod device with an adjustable inward tilting angle. The pull rod device is configured on a door or window and connects the door / window frame and the door / window sash respectively. The pull rod device includes a pull rod base 1, a pull rod 2, a long rotating rod 3, and a limiting seat 6. The pull rod base 1 is fixed to the door / window sash and has a sliding groove 11 extending along its length. The pull rod 2 is located within the sliding groove 11 and extends along the extension direction of the sliding groove 11. One end of the long rotating rod 3 is pivotally connected to the pull rod 2, and this pivot point can move along the extension direction of the sliding groove 11; the other end is pivotally connected to the door / window frame. The limiting seat 6 is located within the sliding groove 11. The pull rod 2 has a locking seat 7 for cooperating with the limiting seat 6.

[0024] When the window is tilted inward, the long rotating rod 3 rotates. At this time, the pivot point between the long rotating rod 3 and the pull rod 2 will move to one side along the extension direction of the slide groove 11. That is, the long rotating rod 3 drives the pull rod 2 to move to one side along the extension direction of the slide groove 11, and then drives the locking seat 7 on the pull rod 2 to move until the locking seat 7 abuts or locks with the limiting seat 6. At this time, the locking seat 7 is limited. At this time, the long rotating rod 3 is at the maximum rotation opening angle (that is, the angle formed between the long rotating rod 3 and the pull rod seat 1 is the largest), that is, the pull rod device is at the maximum tilting opening angle.

[0025] Preferably, the limiting seat 6 and / or the retaining seat 7 are adjustable structures and can move along the extension direction of the slide groove 11 to adjust their positions. Thus, by adjusting the position of the limiting seat 6 and / or the retaining seat 7 within the slide groove 11, the maximum rotational opening angle of the long rotating rod 3 can be adjusted, thereby adjusting the inward tilting opening angle of the pull rod device. Therefore, using the pull rod device of this application, users can adjust the inward tilting opening angle of the door and window sash according to actual needs, thereby ensuring the ventilation efficiency of the door and window sash, adapting it to different usage scenarios, and being compatible with door and window profiles of different thicknesses, making it highly practical.

[0026] Furthermore, in this embodiment, the retaining seat 7 is an adjustable structure while the limiting seat 6 is a fixed structure. Specifically, an external thread 21 is provided on the outer wall of one end of the pull rod 2 along its length direction, and a threaded hole 72 adapted to the external thread 21 is provided on the retaining seat 7. The retaining seat 7 is threadedly sleeved on the external thread 21 of the pull rod 2 through the threaded hole 72. Thus, when the pull rod 2 is rotated, the retaining seat 7 can be moved along the extension direction of the pull rod 2 through the threaded connection, thereby adjusting the position of the retaining seat 7 in the slide groove 11. The limiting seat 6 is fixedly mounted in the slide groove 11. When the position of the locking seat 7 is adjusted to reduce the distance between it and the limiting seat 6, the long rotating rod 3 can rotate a small angle to drive the locking seat 7 to abut or engage with the limiting seat 6, thereby reducing the inward opening and closing angle of the pull rod device. Conversely, when the position of the locking seat 7 is adjusted to increase the distance between it and the limiting seat 6, the long rotating rod 3 needs to rotate a larger angle to drive the locking seat 7 to abut or engage with the limiting seat 6, thereby increasing the inward opening and closing angle of the pull rod device.

[0027] Of course, in other embodiments, the limiting seat 6 can be set as an adjustable structure and the card seat 7 can be set as a fixed structure, or both the limiting seat 6 and the card seat 6 can be set as adjustable structures. Both of these methods can adjust the distance between the card seat 7 and the limiting seat 6, thereby adjusting the inward opening and closing angle of the pull rod device, so they are not limited.

[0028] Preferably, one end of the pull rod 2 has an adjustment hole 22. Preferably, the adjustment hole 22 is a hexagonal slot. Thus, the user can use an adjustment tool inserted into the adjustment hole 22 to drive the pull rod 2 to rotate, thereby adjusting the position of the card holder 7. The operation is simple and convenient, and the adjustment efficiency is high.

[0029] Furthermore, the top of the card holder 7 is also provided with a protrusion 73, and the pull rod seat 1 is provided with a relief groove 12 through which the protrusion 73 can pass; wherein, the pull rod seat 1 is engraved with a scale (not shown in the figure) at the position of the relief groove 12, and the user can know the adjustment amount by pointing to the scale on the scale through the protrusion 73, thereby facilitating the user's adjustment.

[0030] Preferably, the two outer sidewalls of the card holder 7 are respectively in contact with the two inner sidewalls of the slide groove 11, thereby guiding the sliding of the card holder 7 and improving the sliding stability of the card holder 7.

[0031] Furthermore, it also includes a slide block 8 disposed at the other end of the pull rod 2 and slidably disposed within the slide groove 11, with one end of the long rotating rod 3 pivotally connected to the slide block 8 via a pin. In this way, the guiding cooperation between the slide block 8 and the slide groove 11 can improve the movement stability of the pull rod 2, thereby improving the stability of the inward opening and closing.

[0032] See also Figure 4-5 The card holder 7 and the limiting seat 6 are engaged through a snap-fit ​​structure. The snap-fit ​​structure includes a snap-fit ​​block 71 on the card holder 7 and a snap-fit ​​groove 61 on the limiting seat 6. When the long rotating rod 3 drives the pull rod 2 to move along one side of the extension direction of the slide groove 11 until the snap-fit ​​block 71 in the card holder 7 engages with the snap-fit ​​groove 61 on the limiting seat 6, the long rotating rod 3 is limited.

[0033] The card slot 61 includes a buffer slide 611 and a fastening groove 612 that connects to the buffer slide 611. The card block 71 includes a body part 711 and a card head 712 disposed on the body part 711. When the card seat 7 is moved until the card head 712 on the card block 71 extends into the buffer slide 611, the card seat 7 can be buffered. Then the card seat 7 continues to slide until the card head 712 is engaged and fixed with the fastening groove 612. At this time, the card seat 7 is limited (i.e., the long rotating rod 3 is limited), and the body part 711 is located in the buffer slide 611.

[0034] Specifically, the limiting seat 6 is provided with two spring buckles 62 arranged at intervals, and the two spring buckles 62 and the limiting seat 6 define a slot 61; wherein, the maximum width of the card head 712 is greater than the width of the buffer slide 611. When the card head 712 of the card block 71 is inserted into the buffer slide 611, both spring buckles 62 undergo elastic deformation and are stretched open to buffer the card seat 7.

[0035] In this application, when the card holder 7 and the limiting seat 6 are engaged through a snap-fit ​​structure, the snap-fit ​​structure can limit and fix the door and window sash after it tilts inward, thereby improving the stability of the door and window sash after it tilts inward. In addition, the card groove 61 includes a buffer slide groove 611. When the card head 712 of the card block 71 extends into the buffer slide groove 611, the card holder 7 can be buffered, thereby buffering the door and window sash and preventing damage to the pull rod device due to excessive force when tilting the door and window sash inward.

[0036] Therefore, by setting a snap-fit ​​structure, not only can the door and window sashes be limited and fixed after tilting inward, but the door and window sashes can also be buffered. There is no need to set an additional limiting snap-fit ​​structure and buffer, making the pull rod device more compact and more integrated.

[0037] Of course, in other embodiments, the card holder 7 and the limiting seat 6 can also be limited by abutting cooperation, and the door and window sash after inward opening and closing can be limited and fixed by additional limiting carding structure, and the card holder 7 can be buffered by additional buffer. It can also achieve the same technical effect, and is not limited here.

[0038] Of course, in other embodiments, the positions of the card slot 61 and the card block 71 can be interchanged to achieve the same technical effect, so this is not a limitation.

[0039] In addition, the pull rod device also includes a short rotating rod 4, one end of which is pivotally connected to the pull rod seat 1, and the other end is pivotally connected to the long rotating rod 3; wherein, when the door and window sash is opened inward, the long rotating rod 3, the short rotating rod 4 and the pull rod seat 1 form a triangular structure, thereby improving the stability of the door and window sash when it is opened and closed inward.

[0040] In addition, the present invention also provides a door and window system, including a door and window frame, a door and window sash, and the above-mentioned tie rod device, wherein the tie rod seat 1 is fixedly mounted on the door and window sash; preferably, it also includes a plurality of locking bolts 5, which pass through the tie rod seat 1 and press against the door and window sash to achieve fixation.

[0041] In addition, an upper mounting plate is fixed inside the door and window frame, and the other end of the long rotating rod 3 is pivotally connected to the upper mounting plate, thereby realizing the connection between the long rotating rod 3 and the door and window frame.

[0042] In summary, the adjustable inward tilting angle tie rod device and door / window system provided by the present invention have the following beneficial effects: (i) The pull rod device of the present invention allows adjustment of the maximum rotational opening angle of the long rotating rod 3 by adjusting the position of the limiting seat 6 and / or the card seat 7 within the slide groove 11, thereby enabling adjustment of the inward tilting opening angle of the pull rod device. Therefore, by using the pull rod device of this application, users can adjust the inward tilting opening angle of the door and window sash according to actual needs, ensuring the ventilation efficiency of the door and window sash, adapting it to different usage scenarios, and accommodating door and window profiles of different thicknesses, making it highly practical.

[0043] (ii) The pull rod device of the present invention has a locking structure between the card seat 7 and the limiting seat 6 to achieve a locking engagement. This locking structure can limit and fix the door and window sash after it tilts inward, thereby improving the stability of the door and window sash after it tilts inward. In addition, the card groove 61 includes a buffer slide groove 611. When the card head of the card block 71 extends into the buffer slide groove, it can buffer the door and window sash and prevent the door and window sash from being damaged by excessive force when tilting inward.

[0044] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0046] Furthermore, in the description of this invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.
