[0022] Embodiment

[0023] As Figures 1-4As shown in the figure, a stainless - steel corner piece for doors and windows proposed in an embodiment of the present utility model includes a corner piece body 1. Two rectangular holes 2 are opened on the corner piece body 1. A partition block 3 is fixedly connected between the inner walls on both sides of the rectangular hole 2. Four fixing rods 4 are fixedly connected to both sides of the partition block 3. A clamping block 5 is slidably connected to the four fixing rods 4 on the same side. A plurality of springs 6 are fixedly connected between one side of the clamping block 5 and one side of the corresponding partition block 3. The springs 6 are movably sleeved on the corresponding fixing rods 4. A fixed pulley 7 is rotatably connected to both sides of the partition block 3. A flexible steel rope 8 is fixedly connected to one side of the clamping block 5. The end of the flexible steel rope 8 bypasses one side of the corresponding fixed pulley 7 and extends outside the corner piece body 1 and is welded with a pulling block 10. By pulling the pulling block 10, the corresponding two flexible steel ropes 8 are moved. The flexible steel ropes 8 drive the corresponding clamping blocks 5 to move. The clamping blocks 5 slide on the corresponding fixing rods 4. During the movement of the clamping blocks 5, the corresponding springs 6 are compressed. The clamping blocks 5 are received into the rectangular holes 2. The corner piece body 1 is placed at the door and window to be installed and the pulling force on the pulling block 10 is released. At this time, the springs 6 in the compressed state reset. Under the action of the self - elastic force of the springs 6, the springs 6 drive the corresponding clamping blocks 5 to be clamped with the upper interface of the door and window, thereby improving the fixing stability between the corner piece body 1 and the door and window.

[0024] In some embodiments, two limiting grooves 9 with openings on both sides are opened on the corner piece body 1. One inner wall of the limiting groove 9 is in movable contact with one side of the corresponding pulling block 10. The setting of the pulling block 10 plays a connecting role.

[0025] In some embodiments, four circular grooves 11 are opened on one side of the clamping block 5. The clamping block 5 is slidably connected to the corresponding fixing rod 4 through the circular grooves 11. The setting of the circular grooves 11 plays a limiting role.

[0026] In some embodiments, a bending part 12 is provided on the corner piece body 1. A glue injection hole 13 is opened on the corner piece body 1. The bending part 12 is closely attached to the inner wall of the door and window, making the installation of the corner piece body 1 more fitting and flush.

[0027] In some embodiments, two circular holes are opened on one inner wall of the rectangular hole 2. The inner wall of the circular hole is slidably connected to the outer side of the corresponding flexible steel rope 8. The setting of the flexible steel rope 8 plays a connecting role.

[0028] Working principle or structural principle: When in use, pull the pull block 10. The pull block 10 drives the corresponding two flexible steel ropes 8 to move. The flexible steel ropes 8 drive the corresponding clamping blocks 5 to move. The clamping blocks 5 slide on the corresponding fixed rods 4. During the movement of the clamping blocks 5, the corresponding springs 6 are compressed. The clamping blocks 5 are received into the rectangular holes 2. Place the corner piece body 1 at the door or window to be installed and release the pulling force on the pull block 10. At this time, the springs 6 in the compressed state reset. Under the action of the self-elastic force of the springs 6, the springs 6 drive the corresponding clamping blocks 5 to be clamped with the upper interfaces of the door or window, thereby improving the fixing stability between the corner piece body 1 and the door or window. Inject glue into the corner piece body 1 through the glue injection hole 13 to further fix the corner piece body 1 and the door or window. The bending part 12 is closely attached to the inner wall of the door or window, making the installation of the corner piece body 1 more fitting and flush.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
