The invention discloses an anti-pinch torsion spring hinge. The anti-pinch torsion spring hinge comprises a fixed piece, a rotating piece, a lower hinge pin, a torsion spring and an upper hinge pin ofthe hinge and is characterized in that the hinge sequentially comprises a lower cover, a thrust spring, a limiting block, the lower hinge pin, the torsion spring, the upper hinge pin and an upper cover from bottom to top; the lower cover and the upper cover are in threaded connection with the fixed piece, the limiting block is provided with a structure for limiting the rotating angle and the rotating speed of the lower hinge pin, the lower hinge pin is connected with a sliding key groove of the rotating piece, the upper end of the lower hinge pin and the lower end of the upper pin are connected with the torsion spring in an embedded mode, and the upper hinge pin is fixedly connected with the fixed piece. The anti-pinch torsion spring hinge has an automatic reset function, meanwhile, the pre-tightening force of the torsion spring can be set, and the anti-pinch capability is achieved.
本发明公开了一种防夹扭力簧合页，包括合页的固定片，旋转片，下销轴，扭力弹簧，上销轴，其特征在于，所述销轴由下至上依次为：下盖、推力弹簧、限位块、下销轴、扭力弹簧、上销轴和上盖，所述下盖和上盖分别与固定片螺纹连接，限位块上设有限制下销轴旋转角度和旋转速度的结构，下销轴与旋转片滑动键槽连接，下销轴的上端和上销轴的下端分别与扭力簧嵌入连接，上销轴与固定片固定连接。本发明提供的一种防夹扭力簧合页，具有自动复位功能，同时可以设定扭力簧的预紧力并具有防夹能力。
