[0027] As an embodiment of the present invention, further, the bottom bar 1 is provided with a first arc groove on one side close to the first connecting rod 2, and a second positioning rivet 11 is slidably connected inside the first arc groove, and one end of the second positioning rivet 11 is connected to one side of the first connecting rod 2. The first arc groove provides guidance and limit for the movement of the first connecting rod 2, so that the movement trajectory of the first connecting rod 2 is more accurate and stable, and the movement accuracy during the opening and closing of doors and windows is ensured; one side of the bottom bar 1 is rotatably connected with the second connecting rod 3, and a hollow groove is provided on one side of the second connecting rod 3, and the internal sliding connection of the hollow groove is a sliding rivet, and one end of the sliding rivet is rotatably connected to one end of the third connecting rod 4.

Moreover, the cooperation between the hollow groove and the slider can disperse stress, avoid stress concentration, and increase the service life of the door and window hinges.

[0028] As an embodiment of the present invention, further, a second arc groove is opened on the side of the bottom bar 1 close to the second connecting rod 3, and the sliding connection of the second arc groove is provided with a friction screw 13, one end of the friction screw 13 is connected to one end of the second connecting rod 3, and the rotational friction force of the second connecting rod 3 can be adjusted by adjusting the position of the friction screw 13 in the second arc groove, thereby adjusting the resistance when the doors and windows are opened and closed, so that users can set the shape of the first connecting rod 2 to a "Z" shape according to their own needs. This special shape can better adapt to the spatial layout between doors and windows and door frames, optimize the force transmission path, make the force distribution when the doors and windows are opened and closed more uniform, reduce bending and deformation, and at the same time improve space utilization and avoid interference with other components. The connection between the bottom bar 1 and the first connecting rod 2 and the connection between the bottom bar 1 and the third connecting rod 4 are both set to raised reinforcing ribs. This raised manner increases the contact area of ​​the connecting part, can withstand greater stress, and improves the firmness and stability of the connection.

[0029] Specifically, the working principle of this door and window hinge is as follows: when the door and window are pushed or pulled, the bottom bar 1 is used as the basic component, and the first connecting rod 2 rotates around the rotation connection point between the bottom bar 1 and the first connecting rod 2. Since the first connecting rod 2 is in a "Z" shape, its unique shape design can better distribute the force during the rotation process to avoid excessive local force. The first connecting rod 2 slides in the first arc groove of the bottom bar 1 through the second positioning rivet 11. The first arc groove provides guidance and limit for it, making the movement trajectory of the first connecting rod 2 more accurate, and at the same time, the opening and closing angle of the door and window can be fine-tuned. The rotation of the first connecting rod 2 will drive the fourth connecting rod 5 to move. The fourth connecting rod 5 is rotationally connected to the third connecting rod 4 through the first positioning rivet 10, and one end of the third connecting rod 4 is rotationally connected to the bottom bar 1, and one end of the third connecting rod 4 is rotationally connected to the bottom bar 1 through the sliding rivet in the hollow groove on the second connecting rod 3. The second connecting rod 3 is also rotationally connected to the bottom bar 1, and the sliding of the friction screw 13 in the second arc groove can adjust the rotation friction, thereby affecting the resistance to the opening and closing of the door and window. When the second connecting rod 3, the third connecting rod 4 and the fourth connecting rod 5 move in coordination, a linkage system is formed between them, which provides flexible rotation at multiple angles and multiple positions for the opening and closing of doors and windows, thereby realizing the opening and closing of doors and windows. The bending plate at one end of the fifth connecting rod 6 is connected to the adjusting member 7 through the fastening screw 8, and the adjusting member 7 is matched with the square opening on the bending plate through the adjusting member screw 9 to ensure the stability of the adjusting member 7 during the opening and closing of doors and windows. The adjusting member 7 can assist in controlling some actions or functions when the doors and windows are opened and closed. The sealing adjustment component 12 is installed at one end of the bottom rod 1 close to the first connecting rod 2, and its adjustment frame 1201 is connected to the adjustment base 1202 through the adjustment screw 1203. When the adjustment screw 1203 is rotated, the relative position between the adjustment frame 1201 and the adjustment base 1202 can be adjusted, thereby changing the sealing state. This adjustment method can adjust the sealing performance of doors and windows according to different usage environments and needs. For example, when higher sealing requirements are needed, the rotating adjustment screw 1203 is adjusted to move the adjustment seat frame 1201 to reduce the distance with the fourth connecting rod 5, thereby enhancing the sealing effect and improving the air tightness and water tightness of doors and windows. Conversely, the rotating adjustment screw 1203 is adjusted to move the adjustment seat frame 1201 to increase the distance with the fourth connecting rod 5. The connection between the bottom rod 1 and the first connecting rod 2 and the connection between the bottom rod 1 and the third connecting rod 4 are set to be convex, which increases the contact area, so that these key connection parts can withstand greater stress and ensure the firmness of the connection. Secondly, the movement of the hinge is as follows: from the open state to the closed state, when the fifth connecting rod 6 is forced to expand outward, it drives the first connecting rod 2, the second connecting rod 3 and the third connecting rod 4 to make steering activities at the same time through the rivet connection. When a certain angle is reached, the first positioning rivet 10 and the second positioning rivet 11 correspondingly and synchronously limit the opening angle of the hinge.
