Description
Technical Field
The invention relates to the technical field of doors, in particular to a folding door.
Background
Currently, in factories or communities, in order to avoid strangers from entering or exiting at will, a retractable door or a translation door is generally additionally arranged at a doorway. The telescopic door mainly comprises a door body, a driver and a control system. The flexible door body of the telescopic door has large flexible stroke, the driver is driven by a special motor, the worm and the worm wheel are used for reducing speed, and the driver is provided with a manual clutch, so that the door can be manually opened and closed when power fails, a control system of the telescopic door is provided with a control panel and a button switch, and a wireless remote control device can be arranged according to the requirements of users. However, it has the disadvantage of occupying a large space, even in the contracted state, and of occupying part of the width of the channel, thus reducing the width of the channel, which is obviously unsuitable for places where the width of the channel itself is narrow. Compared with the sliding door, the sliding door occupies smaller width of the channel, but still occupies space on two sides of the channel, and the sliding door is difficult to install in the later period due to the fact that the bottom of the sliding door is required to be provided with the track, and the sliding door has certain limitation. To this end, a person skilled in the art proposes a folding and unfolding structure that substantially solves the problem. The invention is characterized by comprising a first door row and a second door row which are hinged with each other, wherein one side of the first door row is rotationally connected with a first fixed upright, a motor driving device for driving the first door row to rotate around the first fixed upright is connected between the first door row and the first fixed upright, and a swing rod device for driving the second door row to reversely rotate relative to the first door row is connected between the upright and the first door row and/or between the first door row and the second door row, so that when the side-hung door is opened or closed, the first door row is driven to rotate around the first fixed upright by the motor driving device, and the first door row drives the second door row to swing in the direction opposite to the first door row by the swing rod device, thereby enabling the second door row and the first door row to be arranged into a straight line and enabling the side-hung door to be in a closed state or mutually folded to be in an open state. When the vertical hinged door of this structure is closed, first door row and second door row fold to one side of passageway and only occupy the space of two door body thickness, can not influence the passageway width because of occupation space is little. However, the second door row is driven synchronously by the motor driving device driving the first door row to rotate around the upright post, in other words, when the first door row is opened or closed, the second door row is driven by the swing rod device to swing in the opposite direction to the first door row. However, the biggest disadvantages of such folding doors are: the structure is more complicated, and the door is when opening the door or closing the door, is realized by pushing or pulling by means of the pendulum rod device, so that when closing the door or opening the door, the door row is easy to deflect to two sides, the fluency of opening and closing the door is influenced, and the stability is poor.
