The invention discloses a hand-squeezing preventing room door. The hand-squeezing preventing room door comprises a door body and a door frame, wherein one side, close to the door body, of the door frame is fixedly connected to two mounting blocks; a fixed shaft is vertically and fixedly connected between the two mounting blocks; a rotary sleeve sleeves the fixed shaft; and the rotary sleeve freelyrotates relative to the fixed shaft. The hand-squeezing preventing room door has the advantages that: once a door body bears relatively great wind force, rotation speed, relative to the fixed shaft,of the rotary sleeve is higher; a mounting cavity is formed in a position, relatively away from the rotary sleeve, of the door body, a counterweight block is provided with certain mass, centrifugal force borne on the counterweight block is greater, elastic pull force of a return spring is overcome, a telescopic bag is extruded and pressed, air in the telescopic bag is introduced into a ring-shapedcavity through a communication tube, and an elastic block is bulged towards the fixed shaft under gas pressure, so that relative great friction force is generated between the fixed shaft and the rotary sleeve to define brake effect; and the door body stops rotation, so that a hand-squeezing accident due to a fact that the door body is rotated at a high speed to close due to relatively great windforce and reaction time is shorter is effectively avoided, and use safety is greatly improved.
本发明公开了一种防夹手房门，包括门体与门框，所述门框靠近门体的一侧固定连接有两个安装块，两个所述安装块之间竖直固定连接有固定轴，所述固定轴上套设有转套，且转套相对固定轴自由转动。优点在于：一旦门体受到较大风力时，转套相对固定轴的转速较快，由于安装腔开设在门体相对远离转套的位置，配重块具有一定质量，则配重块所受到的离心力较大，克服复位弹簧弹性拉力并挤压伸缩囊，将伸缩囊内的空气通过连通管挤入环形腔内，弹性块在气压下朝向固定轴凸起，使固定轴与转套之间产生较大的摩擦力，形成刹车作用，门体停止转动，有效避免因风力较大使门体急速转动关闭而使反应时间较短引起的夹手事故，大大增加了使用安全性。
