Single-power source delay-adjustable control device for automatic multi-leaf door

Abstract

The invention discloses a single-power source delay-adjustable control device for an automatic multi-leaf door. The device comprises a delay length-adjustable control box, a push-pull rod for controlling the opening and the closing of the automatic multi-leaf door, a spring with a buffer function and a connecting rod, wherein one end of the connecting rod is connected with a driving device for driving the automatic multi-leaf door to be opened and closed, and the other end of the connecting rod is fixedly connected with the delay length-adjustable control box; one end of the push-pull rod for controlling the opening and the closing of the automatic multi-leaf door is fixedly connected with a door leaf to be pushed and pulled, and the other end of the push-pull rod extends into the control box; the spring with the buffer function is arranged between the push-pull rod and the sidewall of the control box; the control box can be displaced to a certain extent relative to the push-pull rod under the action of the spring. According to the delay-adjustable control device, the multi-leaf door can be automatically opened, closed, locked and unlocked by virtue of a single power source, so that the number of required motors can be reduced, and cost is lowered, and the multi-leaf door can be controlled and operated more conveniently, safely and reliably.

Description

technical field [0001] The invention relates to an adjustable time-delay control device, in particular to an adjustable time-delay control device for single-action-source automatic multi-leaf doors. Background technique [0002] At present, most of the opening and closing of multiple folding doors are manually operated, which is cumbersome and laborious, and not convenient and fast enough. The multi-leaf doors that open and close automatically are more convenient to operate through electric control of the opening and closing of the doors. If automatic locking and unlocking is added, it will be safer and more reliable, but this usually requires two or more power sources. Realization, which not only increases the cost, but also weakens the reliability. If a single-action source is used to control the opening and closing of automatic multi-leaf doors, as well as automatic locking and unlocking, when the door is closed, the door is not in place, the lock is locked, or the door ...

AI Technical Summary

Problems solved by technology

If a single-action source is used to control the opening and closing of automatic multi-leaf doors, as well as automatic locking and unlocking, when the door is closed, the door is not in place, the lock is locked, or the door is in place, and the drive device cannot move. Problems such as realizing the locking action; when opening the door, there will be a lock that has not been unlocked, and the driving device has begun to push or pull the door, causing the power source to overload; these problems or phenomena are mainly caused by the switch. For automatic multi-leaf doors with lock function, there must be a time difference between the action of opening and closing the lock and opening and closing the door, and it is difficult to obtain such a time difference for automatic multi-leaf doors controlled by a single source of action.
