Description

A side-axis torsion spring return slap door

technical field

The invention relates to the technical field of flapping door structures, in particular to a side-axis torsion spring reset flapping door.

Background technique

At present, automatic ticket checking systems (gates) for rail transit, intelligent building access control, etc., more and more use flapping doors (door stoppers rotate horizontally) as the opening/closing actuators of the channel. Generally, the channel is in a normally closed state. When passengers need to pass, complete (pre) payment or meet the passing demand, the door stopper of the flapping door is opened, and passengers pass through the gate; and the flapping door used in rail transit is technically required to automatically open the flapping door in an emergency such as a power failure. The function that the power failure of existing beat door is opened is realized by extension spring, and its structural representation is as shown in Figure 1: extension spring one end is fixed on the extension spring shaft, and the other end is connected with extension spring belt, and the other end of extension spring belt It is connected with the shaft coupling reset wheel. When assembling, the tension spring has a certain tension, so that the coupling shaft reset wheel always has a unidirectional rotation force, and the coupling shaft reset wheel is connected with the door stop shaft through the connecting key. Therefore, the installation The door stop on the door stop rotating shaft also has a unidirectional rotation force all the time.

When the motor is working, the motor shaft passes through the coupling reset wheel and overcomes the force of the tension spring, so that the door stopper shaft and the door stopper rotate to the required position to achieve the "open" and "close" functions of the door stopper. But no matter where the door stop is, when the gate is powered off, the door stop will rotate to the original position inside the gate on the action line of the tension spring to ensure that the gate channel is opened.

However, since the flapping door stopper can be rotated from 0 to 180 degrees, the extension spring needs to overcome the resistance of the motor to reset the door stopper, so the extension spring needs to have a larger telescopic stroke and a larger pulling force, so that the horizontally placed extension spring It is relatively long, and the whole flapping door needs a larger installation space.
