The invention relates to the technical field of pipe limiting and fixing, in particular to a pipe clamping device, a movable mechanism and an emergency evacuation door grab rail clamping device.The pipe clamping device comprises a mounting base, a connecting rod assembly, a clamping plate assembly and a tightening driving assembly.The connecting rod assembly is folded to achieve stretching and retracting, and the clamping plate assembly is arranged on the mounting base and comprises oppositely-arranged clamping plates; the clamping plates rotate relative to the mounting base, an opening channel is formed between the clamping plates, the connecting rod assembly enters the opening channel after being folded, and when the connecting rod assembly abuts against the tightening driving assembly, the tightening driving assembly drives the clamping plates on the two sides to contract and clamp at least one rod piece of the connecting rod assembly. When the rod piece is folded, the pipe clamping device can be promoted to clamp the rod piece, additional pipe clamping operation is not needed, and operation is convenient.
本发明涉及管件限位固定技术领域,特别涉及一种管夹装置、活动机构和紧急疏散门扶手杆夹紧装置,包括安装座、连杆组件、夹板组件、收紧驱动组件,连杆组件折叠实现伸展和收起,夹板组件设置在安装座上,夹板组件包括相对设置的夹板,夹板相对安装座转动,夹板之间具有开口通道,连杆组件折叠收起后进入开口通道,当连杆组件抵住收紧驱动组件,收紧驱动组件驱使两侧的夹板收缩并夹紧在连杆组件的至少一个杆件上,本发明的管夹装置通过与连杆组件联动,杆件收拢时即可促使管夹装置夹住杆件,不需要额外的管夹操作,便于操作。
