[0027] Two hexagonal screws 8 are inserted and fixedly connected in the horizontal section of the L-shaped frame fixing plate 1, and a positioning opening 101 is opened in the horizontal section of the L-shaped frame fixing plate 1. At the same time, the positioning opening 101 is placed between the hexagonal screws 8 with a spacing, and the protruding ends of the hexagonal screws 8 are inserted into the fixed connection ribs 10, and the ribs 10 are tightly fitted to the horizontal and vertical outer sides of the L-shaped frame fixing plate 1.

[0028] After the hexagonal screw 8 is inserted into the L-shaped frame fixing plate 1, the hexagonal screw 8 is connected to the rib 10. In this way, the L-shaped frame fixing plate 1 and the rib 10 are both installed in the frame of the window frame 17, so that the load-bearing capacity of the entire hinge is increased and it is not easy to bend.

[0029] Furthermore, the positioning mouth 101 is inserted below the third rivet 11 of the rotation connection, and a washer 12 is provided on the middle outer cover of the third rivet 11. At the same time, the third rivet 11 is inserted into one end of the rotation connection positioning rod 4, and the upper and lower surfaces of the washer 12 are tightly fitted with the bottom of the positioning rod 4 and the upper side of the horizontal section of the L-shaped frame fixing plate 1 respectively.

[0030] A positioning rod 4 is provided above the L-shaped frame fixing plate 1 , and the two are connected by a third rivet 11 . The positioning rod 4 rotates with the third rivet 11 as a base point.

[0031] Furthermore, the inner side of the L-shaped frame fixing plate 1 is inserted under the rotating connection boss rivet 7, and there is a distance between the boss rivet 7 and the hexagon socket nail 8. The top of the boss rivet 7 is inserted into one end of the rotating connection long connecting rod 3, and a second gasket 16 is provided between the bottom of the long connecting rod 3 and the L-shaped frame fixing plate 1, and the second gasket 16 is sleeved on the outside of the middle part of the boss rivet 7.

[0032] A long connecting rod 3 is provided above the L-shaped frame fixing plate 1 , and the two are connected by a boss rivet 7 . The long connecting rod 3 rotates with the boss rivet 7 as a base point.

[0033] Furthermore, the middle part of the positioning rod 4 is inserted above the eccentric rivet 9 of the rotating connection, and the lower part of the eccentric rivet 9 is inserted into the middle part of the rotatable connecting long connecting rod 3. The middle part of the eccentric rivet 9 is provided with a first gasket 15 on the outer sleeve, and the upper and lower surfaces of the first gasket 15 are tightly fitted with the bottom of the positioning rod 4 and the upper part of the long connecting rod 3 respectively.

[0034] After the eccentric rivet 9 is inserted into the middle of the positioning rod 4 and the long connecting rod 3, the eccentric rivet 9 can be rotated, so that the window sash can be overlapped and sealed by adjusting the eccentric rivet 9.

[0035] Furthermore, one end of the fan fixing plate 2 is inserted into the upper part of the first rivet 5 of the rotation connection, and the middle part of the first rivet 5 is inserted into the other end of the rotation connection positioning rod 4, while the lower part of the first rivet 5 is inserted into the middle part of the rotation connection long connecting rod 3.

[0036] Furthermore, a second washer 14 is provided on the outer sleeve of the middle portion of the first rivet 5 , and the upper and lower end surfaces of the second washer 14 are tightly fitted with the bottom of the fan fixing plate 2 and the upper end of the positioning rod 4 respectively.

[0037] After the first rivet 5 is inserted into one end of the sash fixing plate 2, the other end of the positioning rod 4 and the middle of the long connecting rod 3, when the sash fixing plate 2 needs to move, the positioning rod 4 and the long connecting rod 3 will limit the moving path of the sash fixing plate 2, causing the sash fixing plate 2 to rotate in a fan shape, thereby opening or closing the window.

[0038] Furthermore, a sliding opening 201 is opened in the middle of the fan fixing plate 2, and the upper part of the second rivet 6 for sliding connection is inserted into the sliding opening 201, and the lower part of the second rivet 6 is inserted into the other end of the rotationally connected long connecting rod 3.

[0039] Furthermore, a first washer 13 is provided on the outer sleeve of the middle portion of the second rivet 6 , and the upper and lower end surfaces of the first washer 13 are tightly fitted with the bottom of the fan fixing plate 2 and the upper part of the other end of the long connecting rod 3 respectively.

[0040] After the second rivet 6 is inserted into the fan fixing plate 2 and the other end of the long connecting rod 3, the fan fixing plate 2 needs to move in a fan shape, so the second rivet 6 is used to slide in the fan fixing plate 2, and at the same time the long connecting rod 3 provides certain support and restriction to the fan fixing plate 2.

[0041] The L-shaped frame fixing plate 1 and the convex rib 10 are fixedly connected to the upper and lower corners of one side of the window frame 17, and the fan fixing plate 2 is fixedly connected to the bottom of the other side of the window frame 17.

[0042] After the L-shaped frame fixing plate 1 and the structure above it are installed in the window frame 17 , the window frame 17 can be opened or closed according to the movement of the sash fixing plate 2 .

[0043] Working principle:

[0044] An inserted hexagonal nail 8 is provided above the horizontal section of the L-shaped frame fixing plate 1, and a convex rib 10 is provided below the hexagonal nail 8, so that the L-shaped frame fixing plate 1 and the convex rib 10 are both installed in the frame of the window frame 17, which increases the load-bearing capacity of the entire hinge. One end of a long connecting rod 3 is provided above the inner side of the horizontal section of the L-shaped frame fixing plate 1, and one end of a positioning rod 4 is provided above the middle of the horizontal section of the L-shaped frame fixing plate 1. The long connecting rod 3 and the positioning rod 4 can be closed or separated at an angle. In this way, after one end of the sash fixing plate 2 is provided above the middle of the long connecting rod 3 and the other end of the positioning rod 4, the movement of the sash fixing plate 2 will have a certain angle. At the same time, the middle of the sash fixing plate 2 is connected to the other end of the long connecting rod 3 by a second rivet 6, so that the moving path of the sash fixing plate 2 is specified. Then, after the sash fixing plate 2 is installed below the window sash edge of the window frame 17, the window sash can be opened or closed according to the action of the sash fixing plate 2.

[0045] In addition, eccentric rivets 9 are inserted in the middle of the long connecting rod 3 and the middle of the positioning rod 4. The eccentric rivets 9 can be adjusted to increase the processing error of the window sash after trial installation.

[0046] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the spirit of the present invention.
