Shutter door electronic lock and operating principle thereof

Abstract

The invention discloses a shutter door electronic lock and an operating principle thereof and relates to the technical field of shutter doors. The shutter door electronic lock comprises a first electronic lock, a pull rod component, a guiding groove and a stroke detection device, wherein the first electronic lock comprises a shell, an iron core, an electromagnetic coil and a reset spring, and the electromagnetic coil and the reset spring are used for driving the iron core to move; the pull rod component comprises a pull rod connected with the iron core, a U-shaped clip and a pull ring, the U-shaped clip and the pull ring are buckled together and are arranged on the pull rod in a sliding mode, and the pull rod is further provided with a bolt used for stretching the U-shaped clip open. The shutter door electronic lock has the advantages that to install the shutter door electronic lock, it is only needed to change original shutter door circuit connection, and a control system does not need to be additionally installed; due to the fact that main components are all located on the inner side of a shutter door, damage can not be caused easily, and anti-theft effect is good; during a power outage, the state of the shutter door electronic lock can be changed manually by a user through the pull ring component, and therefore using is convenient.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to an electronic lock for rolling doors and its working principle. Background technique [0002] The door leaf of the rolling shutter door is a movable door leaf composed of many small door panels connected in series. In order to improve the anti-theft performance of the rolling door, a mechanical lock is usually installed on the door leaf of the rolling door. Although the mechanical lock increases the anti-theft performance of the rolling door, manual operation is required each time the lock is opened and closed, and the process of opening and closing the lock is cumbersome and wastes a lot of time; if the user forgets to unlock and start the rolling door motor, it is easy to cause damage to the rolling door motor; and The existing mechanical lock is easy to be destroyed, and the anti-theft effect is insufficient. Therefore, it is necessary to design a safe and convenient e...
