Gates are control mechanisms for large traffic passage between unauthorized and authorized zones in public applications. The subway gate is widely applied and serves as isolation equipment for paid areas and unpaid areas of subway stations. At present, rail transit, intelligent management and other fields increasingly adopt a gate with a column rotary structure as an execution component, and the gate is relatively beautiful in appearance, simpler in structure compared with a shear type gate and a three-rod type gate, smaller in size, more convenient to maintain and popular; the gate passage is closed under normal conditions, and in order to ensure that pedestrians are evacuated safely or other requirements are required to be cleared quickly under emergency conditions such as fire or power failure, the power failure door opening becomes one of the more and more essential functions. The existing rotary gate mechanism is mostly realized by adding a tension spring, a traction belt or other linear non-elastic elements outside.

When the mechanism normally works, the motor drives the rotating shaft to rotate, the rotating shaft drives the fixedly connected traction belt to stretch the tension spring, so that the door leaf is stopped at different positions, the tension force always exists, when the door leaf is positioned at the door opening position, the door closing position or any intermediate position, the mechanism is powered off, and the door leaf can be restored to the door opening position initially set due to the tension force always possessed by the tension spring, and the door opening reset is realized.

Because the rotary door leaf mechanism has larger movement angle and needs to rotate forward and backward by 90 degrees, the length of the tension spring stroke and the length of the traction belt are both longer, and the tension spring mechanism needs independent space for installation and arrangement, so that the occupied space of the whole mechanism is increased.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 2: the embodiment discloses a self-resetting rotating shaft rotary gate fan door, including a leaf door pivot 1, door leaf 2 and be used for driving the rotatory power unit of a leaf door pivot 1, a leaf door pivot 1 connects in door leaf 2, this embodiment still includes reset module 3, reset module 3 includes dabber 11, mount 12, torsional spring 13 and positioning disk 14, the both ends of dabber 11 are connected respectively in power unit, a leaf door pivot 1, positioning disk 14 connects in dabber 11, torsional spring 13 cup joints in dabber 11, and both ends are connected respectively in positioning disk 14, mount 12 sets up between a leaf door pivot 1 and power unit, and a leaf door pivot 1 can rotate for mount 12, torsional spring 13 has the moment of torsion that makes a leaf door pivot 1 open the direction rotation to door leaf 2.

The present embodiment further includes a bracket assembly 4, and the power mechanism and the fixing frame 12 are both connected to the bracket assembly 4.

Preferably, the power mechanism is a servo motor 5, the power output end of the servo motor 5 is connected with the spindle 11, and the axis of the servo motor 5 is preferably perpendicular to the door rotating shaft 1, so that the overall size, especially the height, of the door of the embodiment can be reduced.

The switching of the transmission angle between the two is realized by a speed change mechanism which is arranged between the rotating shaft 1 of the door leaf and the servo motor 5.

During operation, the servo motor 5 drives the door leaf rotating shaft 1 to rotate through the mandrel 11, so that opening and closing of the door leaf 2 are achieved, in the process, the positioning disc 14 rotates synchronously with the mandrel 11, and the other end of the torsion spring 13 is connected to the fixing frame 12, so that in the opening and closing processes of the door leaf 2, the torque of the torsion spring 13 also changes, but the torsion spring 13 can always provide elastic torque for opening the door leaf 2 for the positioning disc 14.
