Limiting device for emergency evacuation automatic door
The invention discloses a limiting device for an emergency evacuation automatic door, and belongs to the field of emergency evacuation automatic doors. The limiting device comprises a connecting rod and a limiting mechanism. One end of the connecting rod is hinged to a door frame of the emergency evacuation automatic door. The limiting mechanism comprises a sliding block, a sliding way and a limiting assembly, wherein the sliding block is slidably inserted into the sliding way, the sliding block is hinged to the other end of the connecting rod, the sliding way is used for being installed on the top of the fixed sash or the movable sash, a first spring is arranged at one end of the sliding way, the limiting assembly comprises a guide pipe and a limiting bead, the guide pipe is located on the sliding way, one end of the guide pipe is communicated with the sliding way, the limiting bead is slidably arranged in the guide pipe and protrudes out of the guide pipe, and the limiting bead and the other end of the guide pipe are connected together through a second spring. According to the limiting device for the emergency evacuation automatic door, a situation that a fixed leaf and a movable leaf are extremely prone to rotating due to external factors in the side-hung opening process can be avoided, and the side-hung opening state is kept.
本发明公开了一种用于紧急疏散自动门的限位装置，属于紧急疏散自动门领域。所述限位装置包括连杆和限位机构。连杆的一端用于铰接在紧急疏散自动门的门框上。限位机构包括滑块、滑道和限位组件，滑块可滑动地插装在滑道中，滑块和连杆的另一端铰接，滑道用于安装在固定扇或者活动扇的顶部，滑道的一端具有第一弹簧，限位组件包括导向管和限位珠，导向管位于滑道上，且导向管的一端和滑道连通，限位珠可滑动地布置在导向管中，限位珠凸出导向管布置，且限位珠和导向管的另一端通过第二弹簧连接在一起。本发明提供的一种用于紧急疏散自动门的限位装置，可以避免固定扇和活动扇在平开的过程中极易受外界因素发生转动，保持平开的状态。
