[0034] Furthermore, in a preferred embodiment, the side plate 11 and the transverse plate 12 have the same width and are not less than the thickness of the fan glass.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0036] Based on the above, this utility model also has the following embodiments:

[0037] In a further embodiment of this utility model, the corner piece 1 is made of Q235A. During the processing, the surface is required to be flat and free from cracks, burrs, and mechanical damage. Its surface is galvanized with a corrosion resistance of 96H or higher. At the same time, the coating surface should be free from defects such as bubbles, watermarks, and exposed substrate.

[0038] In a further embodiment of this utility model, the inner side of the corner piece 1 is covered with 2mm thick foam to prevent the corner piece 1 from directly contacting the sash glass and to prevent the glass from being bumped.

[0039] In a further embodiment of this utility model, the side plate 11 and the transverse plate 12 have the same length. The thickness of the top end of the side plate 11 is less than the thickness of its bottom end. The thickness of the end of the transverse plate 12 connected to the side plate 11 is less than the thickness of its other end. The thickness of the end of the transverse plate 12 connected to the side plate 11 is the same as the thickness of the top end of the side plate 11. The thickness of the other end of the transverse plate 12 is the same as the thickness of the bottom end of the side plate 11. This is to achieve the corner piece 1 fitting with the bottom corner of the hinge side of the sash glass, so that the sash glass is tilted towards the hinge side.

[0040] In a further embodiment of this utility model, the corner piece 1 is assembled to the lower corner of the fan profile on the fan hinge side by multiple screws 3. The corner piece 1 lifts the fan glass and tilts it towards the fan hinge side at a certain angle, such as... Figure 2 The diagram shows the direction of movement of the sash glass under the action of corner piece 1. At this time, the bottom of the sash glass is higher on the handle side than on the hinge side. The glass tilts towards the hinge side along the tilt angle of corner piece 1, and the weight is biased towards the hinge side, which effectively delays the occurrence of corner falling off the sash handle side, improves the comfort of using the product, and extends the product life.

[0041] In a further embodiment of this utility model, the sash body and the door / window frame profile are rotatably connected by multiple hinges. When the sash body is in the open state, it is in a suspended state. The multiple hinges pull the sash body to prevent it from falling. However, due to the sash body's own weight, the sash body, which is in a suspended state for a long time, will tilt downwards towards the handle side due to its large weight, commonly known as corner dropping, which affects the sealing performance of the door and window. The mass of the sash body mainly comes from the mass of the insulated glass. By adjusting the mass distribution of the insulated glass in the sash body, the occurrence of corner dropping can be delayed, and the service life of the door and window can be extended. This utility model uses corner piece 1. By designing the thickness variation of its side plate 11 and the thickness variation of its transverse plate 12, the glass is tilted towards the hinge side along the tilt angle of corner piece 1, and the weight is biased towards the hinge side, which effectively delays the occurrence of corner dropping on the handle side of the sash and extends the product life. This structure utilizes the lever principle. A fan that is constantly suspended will tilt downwards towards the handle side due to its significant weight. This is because the fan's center of gravity is located in its middle, at half its width. The hinge pulls the fan to prevent it from drooping. The torque m on the hinge is: Torque (m) = Effort (F) × Effort arm (L). The effort F of the fan is its own weight G, and the effort arm L0 is half its width. By setting corner piece 1, the fan glass tilts towards the hinge side along the tilt angle of corner piece 1. The center of gravity of the fan glass shifts towards the hinge side, and the center of gravity of the fan also shifts towards the hinge side. The effort arm L1 of the fan is less than half its width. The effort F, i.e., its own weight G, remains unchanged. Since L1 < L0 and GL1 < GL0, the torque m on the hinge decreases, effectively delaying the drooping phenomenon on the handle side and extending the product's lifespan.

[0042] In a further embodiment of this utility model, the lengths of the side plate 11 and the transverse plate 12 are similar or the same, and the length error must be within 0 to 1 mm.

[0043] In a further embodiment of this utility model, the side plate 11 and the transverse plate 12 have the same length, both being 120mm. The thickness of the end of the transverse plate 12 connected to the side plate 11 is the same as the thickness of the top end of the side plate 11, and the thickness of the other end of the transverse plate 12 is the same as the thickness of the bottom end of the side plate 11. The thickness of the top end of the side plate 11 is less than its bottom end thickness, with a top end thickness of 4mm and a bottom end thickness of 5mm. With this structure, the angle between the outer side of the side plate 11 and the outer side of the transverse plate 12 is 90 degrees, the angle between the inner side of the side plate 11 and the inner side of the transverse plate 12 is 90 degrees, the angle between the outer side of the side plate 11 and the inner side of the transverse plate 12 is 89.5 degrees, and the angle between the inner side of the side plate 11 and the outer side of the transverse plate 12 is 90.5 degrees. This achieves a 0.5-degree tilt of the fan glass towards the hinge side, thereby shifting the center of gravity of the fan body towards the hinge side.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
