Description
Technical Field
The utility model relates to a technical field that the baffle resets specifically is damping formula baffle is from canceling release mechanical system.
Background
At present, the automatic recharging/ticketing system of rail transit and theater scenic spots mostly adopts a baffle self-resetting mechanism as an opening/closing actuator of a bin part. In general, the door of the hopper is in a normally closed state, and a user pushes the baffle open to finish the actions of ticket taking, recharging, change giving and the like in the hopper, as shown in fig. 1; the baffle mechanism used by the automatic recharging/ticket selling system technically requires that the baffle can be automatically reset and closed after a user finishes actions such as ticket taking, recharging, change giving and the like, the baffle is called self-resetting, the self-resetting function of the existing baffle is realized by a tension spring or a torsion spring, and the baffle is fixed with a baffle rotating shaft through a screw nut and can rotate along with the baffle rotating shaft. When the door stop is pushed away under the action of external force, the tension spring or the torsion spring is tightened. When the external force disappears, the tension spring and the torsion spring start to reset, and under the action of the tension spring or the torsion spring, the baffle rotates around the baffle rotating shaft to return to the initial position (the bin hopper is in a door closing state), so that the self-resetting of the baffle is realized.
The existing tension spring or torsion spring self-resetting baffle mechanism has the following defects:
1. the baffle is too fast to clamp the hand easily in the resetting process, and because the baffle always has an acting force to the hand when being pushed away, the baffle can move along with the hand when the hand is retracted until the baffle returns to the initial state. In the process, the hand can be clamped in a gap between the baffle and the hopper, so that the hand clamping condition is caused, the personal safety is damaged, and the safety is a non-negligible risk point.
And 2, the reset moment is not constant, and the reset moment is different along with the position of the baffle plate regardless of the reset of the tension spring or the reset of the torsion spring, so the reset speeds are different. When the baffle moves to the farthest position and resets, the movement speed is high, impact can be caused to the limiting mechanism and the baffle, and the service life is influenced.
3, the noise is high, and because the speed is high in the reset stroke of the tension spring and the torsion spring baffle reset mechanism, the sound generated when the tension spring and the torsion spring baffle reset mechanism return to the initial position and stop is high, so that high noise is caused.
