Description

Magnetic buckle Technical Field The invention relates to a safety buckle, in particular to a magnetic buckle. Background The safety buckle generally comprises a box 20 and a pin 10, wherein the pin 10 is provided with a mating lock portion 11, the box 20 is provided with a lock hole 21, and the mating lock portion 11 is inserted into the lock hole 21 to enable the pin 10 and the box 20 to be in locking connection. The pin 10 and the box 20 can also be separated from each other by operating unlocking. Generally, the locking structure of the female buckle 20 is generally composed of a locking hole 21 and a locking portion 231 whose position can be changed. When the locking part 231 extends out of the lock hole 21, it can act as a locking function to lock the mating lock part 11 in the lock hole 21, so that the male buckle 10 and the female buckle 20 are in locking connection. When the latch 231 is withdrawn from the lock hole 21, the mating lock 11 can freely enter and exit the lock hole 21 and withdraw from the lock hole 21, so that the pin 10 and the box 20 can be separated. When the pin 10 and the box 20 are inserted, the lock part 231 is pressed by the lock part 11, the lock part 231 is moved away by the pressing of the lock part 11 to enable the lock part 11 to continue to advance, and when the lock part 11 is completely inserted into the lock hole 21, the lock part 231 is required to automatically move back to the original state to lock the lock part 11, so that the locking connection of the pin 10 and the box 20 is realized. Therefore, in the process of inserting the locking portion 11 into the locking hole 21, the locking portion 231 needs to be automatically restored to the original position for locking after being passively removed. Therefore, in the conventional safety buckle, the elastic members 254 are required to be provided in the female buckle 20, and the movement of the latch 231 is provided with an opportunity by using the elastic force of the elastic members 254, so that the latch 231 can be pushed by the locking portion 11, and the automatic locking of the latch 231 is realized by using the elastic force of the elastic members 254. For example ZL201910147794.7.
