The invention belongs to the technical field of portal crane windproof zippers, and particularly relates to a portal crane windproof zipper mechanism convenient to operate, which comprises an annular fixing frame, U-shaped mounting frames are fixedly connected to the front surface and the back surface of the annular fixing frame, and pressure bearings are fixedly embedded into the side surfaces, close to each other, of the two U-shaped mounting frames. According to the portal crane windproof zipper mechanism convenient to operate, by arranging a U-shaped buckle and a positioning screw, a zipper locking rope can be conveniently connected with a portal crane through the U-shaped buckle and the positioning screw, a vertical plate, a clamping plate, a telescopic spring, a limiting plate and a limiting block are matched, when the portal crane moves, a positioning wheel can be pulled to rotate, the telescopic spring is compressed by the clamping plate, and the portal crane is prevented from being damaged. The door machine is convenient to move, a rotating rod can be conveniently driven to rotate in an inner ring of a pressure bearing through rotation of a rotating motor, meanwhile, a positioning wheel is driven to rotate, in addition, through limiting of a limiting block, a clamping plate and a limiting plate, the door machine can be conveniently positioned, and the situation that the door machine moves when encountering strong wind suddenly is avoided.

    本发明属于门机防风拉锁技术领域,尤其为一种方便操作的门机防风拉锁机构,包括环形固定架,所述环形固定架的正面和环形固定架的背面均固定连接有U型安装架,两个所述U型安装架相互靠近的一侧面均固定镶嵌有压力轴承。该方便操作的门机防风拉锁机构,通过设置U型卡扣和定位螺钉,利用U型卡扣和定位螺钉可以方便将拉锁锁绳与门机进行连接,并配合立板、卡板、伸缩弹簧、限位板和限位块,门机在移动时能够拉动定位轮旋转,且使卡板压缩伸缩弹簧,方便门机移动,利用转动电机的旋转能够方便带动转动杆在压力轴承的内圈旋转,同时带动定位轮转动,另结合限位块、卡板和限位板的限位,能够方便对门机进行定位,避免其突遇大风时移动的情况出现。
