The invention belongs to the field of classroom doors, and particularly relates to an anti-pinch classroom safety door. The anti-pinch classroom safety door comprises a door frame, a door leaf, a sliding plate, clamping hooks, a damping rod, a spring A, hinges, steel wire ropes, a limiting block, a spring B, clamping blocks, a spring C and an L-shaped rod, the door leaf with the width smaller thanthat of the inner side of the door frame is hinged to the door frame through two symmetrically-distributed hinges, and the sliding plate as high as the door leaf is horizontally and slidably matchedin a sliding groove A in the side end of the door leaf. In the opening process of the door leaf, the sliding plate is pulled back into the door leaf through the two steel wire ropes which are furthertightened gradually, the contraction state of the sliding plate in the door leaf is fixed through the interaction of the two clamping hooks on the sliding plate and the two clamping blocks on the doorleaf, and the hands at the inner edge of the door frame are prevented from being pinched when the door leaf is quickly closed towards the door frame.
本发明属于教室门领域，尤其涉及一种防夹手的教室安全门，它包括门框、门扇、滑板、卡钩、阻尼杆、弹簧A、合页、钢丝绳、限位块、弹簧B、卡块、弹簧C、L杆，其中宽度小于门框内侧的门扇通过对称分布的两个合页与门框铰接，门扇侧端的滑槽A中水平滑动配合有与门扇等高的滑板；本发明通过门扇打开过程中通过两个逐渐进一步绷紧的钢丝绳将滑板拉动回缩至门扇内并通过滑板上两个卡钩与门扇上两个卡块的相互作用对滑板在门扇内的收缩状态进行固定，防止门扇在向门框快速闭合时对撑扶与门框内沿处的手造成夹伤。
