Embodiment 1
[0028] Embodiment 1: The displacement of the core part of the electromagnet is set to be equal to or slightly greater than the distance between the locking groove 5.1 and the limiting part 5.2.
Embodiment 2
[0029] Embodiment 2: The limit portion 5.2 is set high enough so that the stop pin 206 can enter the limit portion 5.2 from the lock groove 5.1 without exceeding the limit portion 5.2.
Embodiment 3
[0030] Embodiment 3: The bracket is also provided with a second guide post 305, and the second guide post 305 is arranged under the swing plate 5, wherein, when the hook plate 2 is locked, it is used to limit the The degree of downward rotation of the swing plate 5 prevents the two swing plates 5 from turning downward excessively due to the excessive lifting of the stop pin 206, and the stop pin 206 cannot be stuck in the limit portion 5.2.
[0031] When locking, touch the two swinging plates 5 to make the swinging plates 5 rotate, and the locking limit part formed by the two limiting parts 5.2 releases the locking limit function, and the hook plate 2 falls into the locking recess under the action of gravity. Groove 5.1, under the action of gravity of the hook plate 2, the swing plate 5 swings until the two locking grooves 5.1 overlap, so that the stop pin 206 falls into the locking groove 5.1 to complete the locking.
[0032] The invention discloses an electromagnetic lock co...
