[0002] A hinge is a device that connects two objects, usually used for the assembly of furniture and buildings such as doors and windows. It consists of two metal plates, one of which is fixed to one object and the other is fixed to another object. The two metal plates are connected to each other by a set of pins (also called screws) and allow the objects to rotate relative to each other. The material of the hinge can be steel, copper, aluminum, etc. The existing hidden casement screen window hinges on the market can only be opened at 90° and cannot be opened at a large angle. In addition, the existing hinges cannot be used synchronously on doors and windows with flush frames and sashes. At the same time, the sealing strip needs to be cut during installation, which reduces the integrity of the seal.

A second rivet 8 is provided in one end of the fan fixing plate 4 and the other end of the positioning rod 2, and a shaft sleeve 10 is provided in the middle part of the second rivet 8. The L-shaped frame fixing plate 1, the connecting plate 5, the positioning rod 2, the long connecting rod 3 and the fan fixing plate 4 are arranged upward in the same vertical line, and the L-shaped frame fixing plate 1 and the fan fixing plate 4 are provided with a first rivet 6 and a clamping block 7.

[0025] The connecting plate 5 is fixedly connected through the upper middle part of the L-shaped frame fixing plate 1, and one end of the positioning rod 2 is rotatably connected to the upper part of the connecting plate 5. A third positioning hole 12 is opened in the middle part of the L-shaped frame fixing plate 1, the connecting plate 5 and one end of the positioning rod 2. The third positioning hole 12 is inserted into and fixedly connected with a third rivet 9, and the nail head of the third rivet 9 is placed above one end of the positioning rod 2.

[0026] After the third rivet 9 is inserted into the L-shaped frame fixing plate 1 and the positioning rod 2, the positioning rod 2 can rotate with the third rivet 9 as a base point.

[0027] Furthermore, one end of the L-shaped frame fixing plate 1 is rotatably connected to one end of the long connecting rod 3, and a fourth positioning hole 13 is opened in one end of the L-shaped frame fixing plate 1 and one end of the long connecting rod 3, and the second rivet 8 is inserted and fixedly connected in the fourth positioning hole 13, and the nail head of the second rivet 8 is placed above one end of the long connecting rod 3.

[0028] After the second rivet 8 is inserted into the L-shaped frame fixing plate 1 and the long connecting rod 3, the long connecting rod 3 can rotate with the second rivet 8 as a base point.

[0029] Furthermore, another section of the long connecting rod 3 is placed above the positioning rod 2 and the third rivet 9 with a distance, and there is a gap between the other end of the positioning rod 2 and the inner side of the vertical end of the L-shaped frame fixing plate 1, and there is a gap between the bottom of the positioning rod 2 and the top of the L-shaped frame fixing plate 1.

[0030] When the positioning rod 2 and the long connecting rod 3 are both rotating, due to the layered arrangement, the L-shaped frame fixing plate 1, the positioning rod 2 and the long connecting rod 3 will not generate friction to hinder the rotation.

[0031] The other end of the long connecting rod 3 is rotatably connected to the middle part of the fan fixing plate 4 , and the other end of the long connecting rod 3 and the middle part of the fan fixing plate 4 are both provided with a second positioning hole 31 .

[0032] Furthermore, a second rivet 8 is inserted and fixedly connected into the second positioning hole 31 , and the head of the second rivet 8 is placed above the middle of the fan fixing plate 4 . A gasket 11 is arranged outside the middle of the second rivet 8 , and the gasket 11 is placed between the fan fixing plate 4 and the long connecting rod 3 to fit tightly.

[0033] Furthermore, there is a distance between the bottom of the fan fixing plate 4 and the upper plane of the long connecting rod 3 , and one end of the fan fixing plate 4 extends beyond the long connecting rod 3 , and the extending end of the fan fixing plate 4 is placed vertically above the other end of the positioning rod 2 .

[0034] When the protruding end of the sash fixing plate 4 is placed above the L-shaped frame fixing plate 1 in a vertical direction with the positioning rod 2 , the sash fixing plate 4 and the positioning rod 2 cannot protrude beyond the vertical end of the L-shaped frame fixing plate 1 for the sake of mobility.

[0035] Furthermore, a first positioning hole 21 is opened in the protruding end of the fan fixing plate 4 and the other end of the positioning rod 2 , and a second rivet 8 is inserted and fixedly connected in the first positioning hole 21 , and the head of the second rivet 8 is placed above the fan fixing plate 4 .

[0036] Furthermore, a rotatable connecting sleeve 10 is sleeved on the middle part of the second rivet 8, and the upper and lower planes of the sleeve 10 are tightly fitted with the bottom of the fan fixing plate 4 and the upper plane of the positioning rod 2 respectively.

[0037] After the second rivet 8 is inserted into the fan fixing plate 4 and the long connecting rod 3, the fan fixing plate 4 rotates with the second rivet 8 as the base point, but the second rivet 8 is also inserted into one end of the fan fixing plate 4 and the positioning rod 2, so that the fan fixing plate 4 can only rotate to a certain angle when rotating.

[0038] Two first rivets 6 are inserted and fixedly connected in the middle of the L-shaped frame fixing plate 1, and a clamp block 7 is fixedly connected below the first rivet 6; a first rivet 6 is inserted and fixedly connected in the middle of the fan fixing plate 4, and a clamp block 7 is fixedly connected above the first rivet 6.

[0039] The L-shaped frame fixing plate 1 and the fan fixing plate 4 are both provided with a first rivet 6 and a clamping block 7, and the first rivet 6 and the clamping block 7 are used to connect the external profiles respectively.

[0040] Working principle:

[0041] A connecting plate 5 and a positioning rod 2 are provided above the L-shaped frame fixing plate 1, and the third rivet 9 is used to insert the L-shaped frame fixing plate 1, the connecting plate 5 and the positioning rod 2, so that the positioning rod 2 rotates on the connecting plate 5 with the third rivet 9 under the action of external force, and a long connecting rod 3 and a second rivet 8 are provided at one end of the L-shaped frame fixing plate 1, so that the long connecting rod 3 takes the second rivet 8 as the base point and rotates without touching the top of the positioning rod 2. At the same time, the other end of the long connecting rod 3 and the middle part of the fan fixing plate 4 are also inserted with the second rivet 8. In this way, when the long connecting rod 3 rotates, the fan fixing plate 4 will be separated from the L-shaped frame fixing plate 1 and the positioning rod 2. The positioning rod 2 moves vertically upward, but a second rivet 8 is also inserted into one end of the sash fixing plate 4 and one end of the positioning rod 2, so that under the action of the positioning rod 2, the distance that the sash fixing plate 4 moves away is limited by the positioning rod 2, and the positioning rod 2 is restricted by the third rivet 9 and can only rotate. A first rivet 6 and a clamp block 7 are provided on the L-shaped frame fixing plate 1 and the sash fixing plate 4 to connect the external profile, so that the external profile above the sash fixing plate 4 and the profile below the L-shaped frame fixing plate 1 are opened to a large angle, and the profile connected above the sash fixing plate 4 is the movable side for doors and windows, and the profile below the L-shaped frame fixing plate 1 is the fixed side for doors and windows.

[0042] 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 in similar ways without departing from the spirit of the present invention.
