Description

Technical Field

[0001] The invention belongs to the technical field of automatic locks, and in particular relates to a novel electromechanical automatic lock. Background Art

[0002] An electromechanical automatic lock is a lock that uses a magnetic field to automatically open and close the lock tongue. Compared to ordinary locks, an electromechanical automatic lock requires power to trigger mechanical movement. During the mechanical movement, a certain magnetic field is generated, which draws the lock tongue to the inside of the automatic lock, thereby retracting the lock tongue and realizing the unlocking operation. With the emergence of electromechanical automatic locks, it has replaced many traditional mechanical locks and its application range is becoming more and more extensive.

[0003] Currently, the utility model patent number CN201820481645.5 discloses an electromechanical automatic lock, including a mounting base, a locking mechanism, a control mechanism, a drive mechanism, and a response mechanism; the drive mechanism includes a motor; the control mechanism includes a control gear driven by the motor to rotate, a drive assembly capable of driving the locking mechanism to open and close, and a manual control assembly capable of interlocking with the drive assembly. The manual control assembly and the motor are used to realize both electric control and manual control opening and closing modes. When manually controlled, the control gear and the drive wheel are in a non-interlocking state. At this time, the movement of the manual control assembly does not drive the control gear to rotate, thereby preventing the electric control and manual control from interfering with each other, avoiding the rotation of the drive wheel during manual control and causing the motor output shaft to rotate when the motor is not working, causing damage to the motor. However, the automatic lock structure of this application is relatively complex, and it is easy to jam during the transmission process. If the lock is damaged, it is not very convenient to disassemble and repair it later.

[0004] Therefore, the problem of jamming that easily occurs during the transmission process of the above-mentioned automatic lock needs to be solved urgently to improve the usage scenarios of the automatic lock. Summary of the Invention

When the electric lock is used, the magnetic field generates a certain magnetic field, which makes the electromagnetic lock cylinder lift up, thereby separating the electromagnetic lock tongue on the lower side of the electromagnetic lock cylinder from the rolling door chassis, so that the track and the rolling door chassis can be separated, and then push the track to the left to separate the track from the rolling door chassis. If the electromagnetic lock body cannot be powered on, the emergency lock body can be used to move the lever piece body to the back When the left side of the lever piece body is lifted upward, the electromagnetic lock tongue is pushed to the outside of the rolling door chassis, so that the electromagnetic lock tongue is separated from the rolling door chassis, and then the track is moved to the left; through the setting of the lever piece body, the electromagnetic lock body and the emergency lock body can be linked, and the emergency lock body presses the right side of the lever piece body downward, so that the left side of the lever piece body is lifted upward. When the left side of the lever piece body is lifted upward, the electromagnetic lock tongue is driven to lift upward, so that the electromagnetic lock tongue is separated from the rolling door chassis, which is convenient for use when the electromagnetic lock body is damaged. The lever piece body can avoid jamming during transmission, and the whole structure is simple. If the lock is damaged, it is also very convenient to disassemble and repair it later.
