Side-shaft torsion spring resetting swing turnstile

Abstract

The invention provides a side-shaft torsion spring resetting swing turnstile. The automatic retracting function of the swing turnstile after outage is ensured, and the occupied space is shortened. Theside-shaft torsion spring resetting swing turnstile comprises a bottom plate, the bottom plate is fixedly connected with a main supporting plate through supporting rods, the main supporting plate isfixedly connected with a motor, and an upper output shaft of the motor is connected with the lower portion of a connecting hole of a shaft-coupling resetting wheel; and a door stop rotating shaft is mounted on the upper portion of the connecting hole of the shaft-coupling resetting wheel in an inserted mode, and the upper output segment of the door stop rotating shaft is connected with a door stop. The side-shaft torsion spring resetting swing turnstile is characterized in that the shaft-coupling resetting wheel is connected with a resetting driving wheel located on one side of the shaft-coupling resetting wheel through a linear structure, and the resetting driving wheel is connected with a torsion spring assembly with certain torsion at the initial state; the torsion spring assembly comprises a torsion spring, a torsion spring mandrel and a torsion spring seat plate; and the torsion spring is arranged on the vertically-arranged torsion spring mandrel in winding and rotating modes, andthe torsion spring mandrel and the upper output shaft are arranged in a parallel state.

Description

technical field [0001] The invention relates to the technical field of flapping door structures, in particular to a side-axis torsion spring reset flapping door. Background technique [0002] 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 of opening the power failure of the existing flapping door is realized by the extension spring, and its structure is shown as figure 1 Shown: One end of the extension spring is f...

Problems solved by technology

[0004] 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 entire flapping door requires a large installation space
