Direct drive swing door control mechanism

Abstract

The invention discloses a direct-drive type side-hung door control mechanism. The direct-drive type side-hung door control mechanism comprises a motor fixed on a mounting plate, and further comprises a reset device and a peripheral positioning device, wherein a rotary shaft of the motor is in transmission connection with a door shaft; when the door shaft is positioned at an initial angle position, a door leaf connected with the door shaft and a plane of a door frame externally corresponding to the door leaf form an included angle; the reset device is connected between the door shaft and the mounting plate and used for providing acting force for rotating the door shaft to the initial angle position; the peripheral positioning device is connected with the mounting plate and the motor. The direct-drive type side-hung door control mechanism disclosed by the invention is adopted to brake and stop rotation on the basis of ensuring the normal opening and closing of the door, and capable of realizing automatically opening during power failure. The direct-drive type side-hung door control mechanism has the advantages of being simple in structure, long in service life, small in noise and convenient to maintain.

Description

Technical field [0001] The invention relates to an access control mechanism, in particular to a direct drive type side-hung door control mechanism. Background technique [0002] At present, the requirements for access control mechanisms are getting higher and higher. The existing swing door control mechanisms often fail to open normally or require manual operation to open again during a power outage. Therefore, when the power is out of large passenger flow places such as rail transit, it is easy to cause passenger flow The congestion caused certain safety hazards; at the same time, the structure of the existing swing door control mechanism is often more complicated, and for places with large passenger flow, due to the frequent opening and closing of the swing door, the internal structure of the existing swing door control mechanism is also very easy to wear . Summary of the invention [0003] In view of the above-mentioned defects and existing technical problems of the prior art,...

Problems solved by technology

[0002] At present, the requirements for the access control mechanism are getting higher and higher. The existing swing door control mechanism often cannot be opened normally or needs to be manually operated to open again when the power is cut off. In this way, when the power is cut off in places with large passenger flow such as rail transit, it is very easy to cause passenger flow. At the same time, the structure of the existing swing door control mechanism is often more complicated, and for places with a large passenger flow, due to the frequent opening and closing of the swing door, the internal structure of the existing swing door control mechanism is also very easy to wear
