It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] like Figure 1As shown, the utility model provides a diagonal tie rod for inner casement doors and windows, comprising a door and window leaf mounting seat 1 and a door and window frame connecting assembly, wherein the door and window frame connecting assembly is hinged to the door and window leaf mounting seat 1. The door and window leaf mounting seat 1 is used to connect with the inner casement door and window leaf 9, and the door and window frame connecting assembly is used to connect with the door and window frame. The door and window leaf mounting seat 1 and the door and window frame connecting assembly cooperate with each other to realize the opening and closing of the inner casement door and window.

[0031] like Figure 2 , Figure 3 As shown, in this embodiment, a receiving cavity is provided on the fixed arm of the door and window leaf, and an adjustment assembly 3 is provided in the receiving cavity. The adjustment assembly 3 includes an elastic member 31, an adjustment block 32 and an adjustment member 33. The function of the elastic member 31 is to provide a stable elastic force and a reset force for the adjustment assembly 3, so that the adjustment block 32 always abuts against the adjustment member 33, and ensures that a certain tension and stability can be maintained during the adjustment process. The elastic member 31 can be designed as a spring. Of course, the elastic member 31 can also be designed as other structures that can restore deformation. In actual design, the structure of the elastic member 31 can be designed according to actual needs. In addition, one side of the elastic member 31 abuts against the bottom of the receiving cavity, and at least a part of the other side of the elastic member 31 is sleeved on one side of the adjustment block 32, then the elastic force of the elastic member 31 can directly act on the adjustment block 32, providing the necessary thrust or pull for the adjustment block 32, and the other side of the adjustment block 32 abuts against the adjustment member 33. When the adjustment member 33 moves, the force can be transmitted to the elastic member 31 through the adjustment block 32, thereby realizing the linkage of the entire adjustment assembly 3. Secondly, the accommodating cavity is provided with an internal thread, and the adjusting member 33 is connected to the accommodating cavity thread. By rotating the adjusting member 33, the adjusting block 32 is driven to move leftward or rightward, thereby correcting the corner drop phenomenon of the inner casement door and window. In addition, the adjusting member 33 can be designed as a machine thread, which is connected to the internal thread of the accommodating cavity. Of course, in actual design, the structure of the adjusting member 33 can be designed according to actual needs.

[0032] like Figure 1 , Figures 4 to 6As shown, in this embodiment, the door and window frame connection assembly includes a long arm 21, a short arm 22 and a door and window frame fixed arm 23, one end of the long arm 21 is hinged to the door and window sash mounting seat 1, and the other end of the long arm 21 is connected to the door and window frame fixed arm 23, and the long arm 21 moves between the inner casement door and window sash 9 and the door and window frame, thereby supporting the opening and closing of the inner casement door and window. The short arm 22 is located above the long arm 21, one end of the short arm 22 is hinged to the adjustment block 32, and the other end of the short arm 22 is hinged to the long arm 21, and the short arm 22 can move accordingly with the position change of the adjustment block 32, thereby realizing fine adjustment of the position of the inner casement door and window sash 9. When the inner casement door and window produces corner drop, the inner casement door and window is opened, and the adjusting member 33 is rotated. The adjusting member 33 pushes the short arm 22 to move in the first direction through the adjusting block 32. Since one end of the long arm 21 is hinged to the door and window frame fixing arm 23, and the door and window frame cannot move, the long arm 21 cannot move with the short arm 22. At this time, since the force is mutual, the short arm 22 will give the door and window sash mounting seat 1 a traction force along the second direction, so that the door and window sash mounting seat 1 drives the inner casement door and window sash 9 to move in the second direction. The moving direction of the casement door and window sash 9 is opposite to the direction of the corner drop, which can effectively correct the corner drop phenomenon and restore the door and window sash to a state parallel to the door and window frame, so that the door and window can be opened and closed smoothly, preventing it from affecting the normal use of the inner casement door and window. The first direction is opposite to the second direction, and the first direction and the second direction are parallel to the length direction of the door and window sash mounting base 1, so that the moving direction of the inner casement door and window sash 9 is opposite to the direction of the corner drop, thereby effectively correcting the corner drop phenomenon. During the adjustment process, the inner casement door and window sash 9 will gradually return to a state parallel to the door and window frame, thereby ensuring that the door and window can be opened and closed smoothly.

[0033] like Figure 2 , Figure 3 As shown, in this embodiment, a first connecting hole is provided on the adjusting block 32, and a second connecting hole is provided on the short arm 22. The first rivet 4 passes through the first connecting hole and cooperates with the second connecting hole, so that the connection between the adjusting block 32 and the short arm 22 is not only stable and reliable, but also easy to install and adjust, so that the short arm 22 can move with the adjusting block 32.

[0034] like Figure 1 , Figure 2As shown, in this embodiment, a first waist-shaped hole 11 is provided on the door and window sash mounting seat 1, and the second rivet 5 passes through the first waist-shaped hole 11 and cooperates with the long arm 21. The design of the first waist-shaped hole 11 allows a certain adjustment space for the long arm 21 during the opening or closing of the inner casement door and window sash 9, which facilitates the opening and closing of the inner casement door and window sash 9. In addition, the long axis of the first waist-shaped hole 11 is arranged along the length direction of the door and window sash mounting seat 1. When the inner casement door and window sash 9 needs to be opened, the long arm 21 will move along the long axis direction of the first waist-shaped hole 11, so that the door and window sash can be opened smoothly. Similarly, when closing the door and window sash, the long arm 21 will also move along the long axis direction of the first waist-shaped hole 11, ensuring that the door and window sash can be tightly closed and providing good sealing performance.

[0035] like Figure 1 , Figure 2 As shown, in this embodiment, a third connecting hole is provided on the long arm 21, and a fourth connecting hole is provided on the short arm 22. The third rivet 6 passes through the third connecting hole and cooperates with the fourth connecting hole, that is, the third rivet 6 passes through the long arm 21 and the short arm 22, ensuring a stable connection between the two, maintaining sufficient strength, preventing loosening or deformation, thereby facilitating the opening and closing of the inner casement door and window sash 9.

[0036] like Figure 1 , Figure 5 , Figure 6 As shown, in this embodiment, the door and window frame connection assembly further includes a first connection arm 24 and a second connection arm 25, one end of the first connection arm 24 is hinged to the long support arm 21, the other end of the first connection arm 24 is hinged to the door and window frame fixed arm 23, one end of the second connection arm 25 is hinged to the long support arm 21, and the other end of the second connection arm 25 is hinged to the door and window frame fixed arm 23. Specifically, a second waist-shaped hole 211 is provided on the long support arm 21, the fourth rivet 7 passes through the second waist-shaped hole 211 and cooperates with the second connection arm 25, a third waist-shaped hole 231 is provided on the door and window frame fixed arm 23, the fifth rivet 8 passes through the third waist-shaped hole 231 and cooperates with the first connection arm 24, so that when the inner casement door and window sash 9 is opened or closed, the long support arm 21 realizes the smooth movement and positioning of the inner casement door and window sash 9 through the linkage effect of the first connection arm 24 and the second connection arm 25, thereby ensuring the stability and safety of the inner casement door and window sash 9 during the opening and closing process.

[0037] When the utility model is in use, the inclined rod of the inner casement door and window is installed on the top of the inner casement door and window leaf 9. If the lower left corner of the inner casement door and window leaf 9 is off, the adjusting member 33 is rotated clockwise so that the adjusting block 32 drives the short support arm 22 to move to the left. At the same time, the door and window leaf mounting seat 1 drives the inner casement door and window leaf 9 to move to the right, so that the upper right corner of the inner casement door and window leaf 9 is pulled, which effectively corrects the off corner phenomenon and restores the door and window leaf to a state parallel to the door and window frame, so that the door and window can be opened and closed smoothly.
