Abstract
Description
Technical Field
[0001] This utility model relates to the field of doors and windows, specifically to a door and window transmission rod structure that prevents misoperation. Background Technology
[0002] In common window and door structures such as casement windows and sliding windows, the transmission rod connects the handle, locking points, rocker arm, and other components, converting the rotational force of the handle into linear motion to drive the locking points to extend or retract, or to move the window sash, thus opening and closing the window. However, when users clean or maintain the windows, they may accidentally touch these components, causing the transmission rod to move. This could lead to all locking mechanisms between the window sash and the frame disengaging simultaneously, causing the window sash to detach from the frame. Utility Model Content
[0003] Based on this, and in response to the aforementioned technical problems, this utility model provides a door and window transmission rod structure to prevent misoperation.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A door and window transmission rod structure designed to prevent misoperation includes a first connecting rod installed in a U-shaped groove in the window sash, and a second connecting rod slidably connected to the upper surface of the first connecting rod and capable of sliding along the length of the first connecting rod. A lever is also provided above the second connecting rod, with its fixed end hinged to the second connecting rod and its movable end hinged to a rocker arm. A stop structure is also provided between the first connecting rod and the second connecting rod, which contacts the lever and can restrict the sliding of the second connecting rod relative to the first connecting rod after the lever rotates to disengage from the lever.
[0006] By adopting the above technical solution, and by setting a stop structure, when the paddle rotates to the point of disengaging from the stop structure, the stop structure can be automatically triggered to limit the back-and-forth sliding of the second link relative to the first link along the length direction; and when the paddle rotates to the upper surface of the second link and presses against the stop structure, the limiting effect of the stop structure is released, and the second link can slide back and forth along the first link.
[0007] In a specific embodiment of this utility model: the stop structure includes a fixed block, a movable component, and a spring. The first connecting rod has a sliding groove. The fixed block is located below the first connecting rod. The top of the fixed block has an upwardly protruding boss that passes through the sliding groove and is fixedly connected to the second connecting rod. The top surface of the fixed block also has a downwardly recessed mounting groove. The movable component and the spring are located in the mounting groove. One end of the spring abuts against the bottom wall of the mounting groove, and the other end abuts against the bottom surface of the movable component. The movable component is divided into a stop block and a guide post connected to the upper surface of the stop block. The cross-section of the guide post is smaller than the width of the sliding groove. The second connecting rod has a guide hole corresponding to the position of the guide post. The end of the guide post passes through the guide hole and abuts against the paddle. The width of the stop block is greater than the width of the sliding groove. The sliding groove has a stop notch that matches the contour of the stop block.
[0008] Thus, when the paddle rotates and disengages from the movable part, the spring pushes the movable part upward, causing the stop block to engage in the stop notch of the slide groove. Since the width of the stop block is greater than the width of the slide groove, it forms a limiting structure, thereby preventing the second link from displacing relative to the first link. When the paddle rotates back to its original position, it adheres to the upper surface of the second link, and the paddle exerts downward pressure on the guide post. This pressure pushes the movable part downward against the spring force, causing the stop block to disengage from the stop notch and retract into the mounting groove of the fixed block. The limitation on the second link is then released, and the second link can slide normally relative to the first link.
[0009] In a specific embodiment of this utility model: the front part of the first connecting rod is connected to an upward pin, which is movably disposed in the elongated groove at the front part of the second connecting rod.
[0010] In summary, by setting a stop structure in this utility model, when the lever rotates and disengages from the stop structure, the stop structure can restrict the second link from sliding relative to the first link along the length direction, preventing all locking mechanisms between the window sash and the window frame from disengaging simultaneously and causing the window sash to fall off the window frame; and when the lever rotates to the upper surface of the second link and presses against the stop structure, the limiting effect of the stop structure is released, and the second link can slide along the first link.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 and Figure 2 As shown, this utility model is a door and window transmission rod structure designed to prevent misoperation. It includes a first connecting rod 10 installed in a U-shaped groove in the window sash, and a second connecting rod 20 slidably connected to the upper surface of the first connecting rod 10 and capable of sliding along the length of the first connecting rod 10. A lever 30 is also provided above the second connecting rod 20. The fixed end 31 of the lever 30 is hinged to the second connecting rod 20, and the movable end 32 is connected to the window frame via a rocker arm.
[0021] Combination Figure 3 As shown, a stop structure 40 is provided between the first link 10 and the second link 20. When the lever 30 rotates to the upper surface of the second link 20 and presses against the stop structure 40, the second link 20 can slide forward and backward along the first link 10. When the lever 30 rotates to disengage from the stop structure 40, it can restrict the second link 20 from sliding forward and backward relative to the first link 10, thereby preventing all locking mechanisms between the window sash and the window frame from disengaging simultaneously and causing the window sash to fall off the window frame.
[0022] Combination Figures 4-7As shown, in this embodiment, the stop structure 40 includes a fixed block 41, a movable member 42, and a spring 43. A groove 11 is provided on the first connecting rod 10. The fixed block 41 is located below the first connecting rod 10. The top of the fixed block 41 has an upwardly protruding boss 411 that passes through the groove 11 and is fixedly connected to the second connecting rod. The top surface of the fixed block 41 also has a downwardly recessed mounting groove 412. The movable member 42 and the spring 43 are located within the mounting groove 412. One end of the spring 43 abuts against the bottom wall of the mounting groove 412, and the other end abuts against the bottom surface of the movable member 42. Here, the movable member 42 is divided into a stop block 421 and a guide post 422 connected to the upper surface of the stop block 421. The cross-section of the guide post 422 is smaller than the width of the groove 11. The second connecting rod 20 has a guide hole 21 corresponding to the position of the guide post 422. The end of the guide post 422 passes through the guide hole 21 and abuts against the paddle 30. The width of the stop block 421 is greater than the width of the groove 11. The groove also has a stop notch 12 that matches the contour of the stop block 421.
[0023] Thus, when the lever 30 is positioned on the upper surface of the second link 20 and presses against the movable member 42, the lever 30 exerts downward pressure on the guide post 422. This pressure pushes the movable member 42 downward against the elastic force of the spring 43, causing the stop block 421 to disengage from the stop notch 12 and fully retract into the mounting groove 412 of the fixed block 41. At this time, the restriction on the second link 20 is released, and the second link 20 can slide relative to the first link 10. When the window sash is rotated, the lever 30 rotates synchronously and disengages from the movable member 42, thus relieving the pressure on the movable member 42. If the second link 20 continues to slide relative to the first link, when it slides to the point where the stop notch 12 is exactly above the movable member 42, the spring 43 will push the movable member 42 upward, causing the stop block 421 to embed into the stop notch 12 of the slide groove, forming a limiting structure, thereby preventing the second link 20 from continuing to slide.
[0024] like Figure 1 As shown, in this embodiment, the front of the first connecting rod 10 is connected to an upward-facing pin 12. The pin 12 is movably disposed within the elongated groove 22 at the front of the second connecting rod 20.
[0025] In summary, by setting a stop structure in this utility model, when the lever rotates and disengages from the stop structure, the stop structure can restrict the second link from sliding relative to the first link along the length direction, preventing all locking mechanisms between the window sash and the window frame from disengaging simultaneously and causing the window sash to fall off the window frame; and when the lever rotates to the upper surface of the second link and presses against the stop structure, the limiting effect of the stop structure is released, and the second link can slide along the first link.
[0026] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
