The invention discloses an anti-pinch hinge structure. The anti-pinch hinge structure comprises hinges with protective plates, the left end and the right end of a working table of a foldable platformladder are hinged to two ladder frames through the pair of hinges with the protective plates correspondingly, and each hinge with the protective plate comprises an upper hinge plate, a lower hinge plate, the protective plate and a sleeve. The upper ends of the upper hinge plates are fixedly connected with the working table of the foldable platform ladder, the lower ends of the lower hinge plates are fixedly connected with the ladder frames, and the lower ends of the upper hinge plates, the upper ends of the lower hinge plates and the middles of the protective plates are hinged together; the lower ends of the upper hinge plates are provided with limiting notches facing an extrusion/shearing risk area, limiting rivets are arranged in the middles of the lower hinge plates, and when the lowerhinge plates are unfolded in place, the limiting rivets are limited in the limiting notches; and hooks are arranged at the lower ends of the protective plates and are hooked on the bodies of the limiting rivets. According to the anti-pinch hinge structure, the extrusion hidden danger of the hinges to a hand is removed, the body of a user is effectively protected, and the safety of a product is improved.
一种防夹手铰链结构，包括带防护板的铰链，可折叠平台梯的工作台面的左右两端分别通过一对带防护板的铰链与两个梯架铰接，所述带防护板的铰链包括上铰链板、下铰链板、防护板和套管，上铰链板的上端与可折叠平台梯的工作台面固定连接，下铰链板的下端与梯架固定连接，上铰链板的下端、下铰链板的上端和防护板的中部铰接在一起，上铰链板的下端朝向挤压/剪切风险区域设有限位缺口，下铰链板的中部设有限位铆钉，在下铰链板展开到位时，限位铆钉限位在限位缺口内；防护板的下端设有搭钩，搭钩钩扣在限位铆钉的钉身上。本发明提供了一种防夹手铰链结构，从而去除了铰链对手部的挤压隐患，使用者的身体得到了有效的防护，提高了产品的安全性。
