Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0013] A movable wing reversible rotary door with secondary protection function, comprising a fixed door frame 8, a rotary frame 7, a rotor 5 and a rotary door frame 3, the fixed door frame is two arc doors and mirrored symmetrically arranged to have two gaps A circular door frame is provided with a rotating frame radially at the center of the two fixed door frames. The rotating frame is driven by a motor. The two ends of the rotating frame are respectively equipped with an arc-shaped rotating door frame through two rotors. The arcs are concentric arcs and the arc radius of the revolving door frame is smaller than that of the fixed door frame.

[0014] The two side end surfaces of each revolving door...

Abstract

The invention relates to a moving wing reversely-folded type rotor wing door with a secondary protection function. The rotor wing door comprises fixed door frames, a rotating frame, rotor wings and rotating door frames. The fixed door frames are two arc doors and are arrayed into a circular door frame with two notches in a mirror symmetry mode. The rotating frame is arranged at the center of the two fixed door frames in the radial direction. The two ends of the rotating frame are provided with the arc-shaped rotating door frames through the two rotor wings respectively. The end faces of the two sides of each rotating door frame are each provided with an arc-shaped fan blade through a hinged shaft along the arc extension line of the corresponding rotating door frame, and hinges matched with the hinged shafts are mounted between the arc-shaped fan blades and the rotating door frame. According to the wing reversely-folded type rotor wing door, under the conditions that primary protection of the rotor wing door fails and a motor rotates, the arc-shaped fan blades enable a human body to bear pressure, so that a moving wing of the rotor wing door is reversely folded, and personal safety is protected. The method is called secondary safety protection.

Description

technical field [0001] The invention belongs to the field of safety doors, in particular to a movable-wing reversible rotary-wing door with a secondary protection function. Background technique [0002] When the revolving door encounters pedestrians, rotors and fixed columns approaching a dangerous distance during use, the revolving door stops. This method is the most commonly used safety protection method for rotary wing doors at present, and this method is called the first-level safety protection. In some special circumstances, or the sensor fails, or the signal of the sensor is weakened, or due to a circuit problem, the primary safety protection may fail and cause personal injury. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a movable-wing reflex-folding rotor door with a secondary protection function that can effectively buffer the impact of the rotor. [0004] The present invent...
