[0019] The anti-pinch hinge assembly for doors and windows described in the utility model can be made of the following materials and components, but is not limited to the following materials and components, such as: rubber sheets, bolts, hinges, metal plates, screws, hinges, etc.

[0020] like Figure 1 The figure shows a cross-sectional structure diagram of the unfolded state of the anti-pinch hinge assembly for doors and windows of the utility model embodiment; Figure 2 and Figure 3 .

[0021] The anti-pinch hinge assembly for doors and windows of the present utility model embodiment comprises: a fixing member 1, a rotating member 2 and a shielding member 3; the fixing member 1 is fixed to a door frame 50 on a wall 5. The rotating member 2 is used for fixed connection with a door leaf 4.

[0022] Generally, the fixing member 1 is provided with a plurality of fastening bolts 15, and the fixing member 1 is mounted on the door frame 50 through the fastening bolts 15. The rotating member 2 is provided with a plurality of connecting bolts 25, and is mounted on the door leaf 4 through the connecting bolts 25.

[0023] The fixed member 1 is provided with a rotating shaft 10, and the rotating member 2 is hinged on the rotating shaft 10 and can rotate around the rotating shaft 10; generally, on a hinge assembly, the rotating member 2 is provided with multiple sliding sleeves (generally two or three), and is hinged on the rotating shaft 10 through multiple sliding sleeves.

[0024] The fixed member 1 is provided with an arc contact plate 11; the shielding member 3 has a sliding end and a fixed end, and the cross-section of the shielding member 3 gradually increases from the sliding end to the fixed end; the shielding member 3 is installed on the rotating member 2 through the fixed end, and the shielding member 3 is close to the arc contact plate 11 through the sliding end; the rotating member 2 rotates relative to the fixed member 1 so that the sliding end slides on the arc contact plate 11.

[0025] In order to avoid pinching and reduce noise, the shielding member 3 is a rubber plate.

[0026] In actual use, since the cross-section of the sliding end is very small and the cross-section of the shielding member 3 gradually increases, there will be no obvious clamping structure on both sides of the arc contact plate 11, thereby avoiding clamping of foreign objects or injuring the human body, greatly improving safety.

[0027] In the embodiment of the utility model, a gradually changing shielding member contacts the arc contact plate on the fixing member, so that when the hinge assembly is closed, no severe squeezing of the space is generated, thereby avoiding pinching of personnel.
