Detailed Description

Specific embodiments of the present invention are described with reference to the above drawings.

As can be seen from fig. 1 to 3, the safety door lock mechanism of the present invention includes a main lock mechanism 10 and a lock mechanism 30 controlled by the main lock mechanism 10 through a connecting mechanism 20, wherein the lock mechanism 30 includes a locking tongue 31 having a wedge-shaped locking end, the locking tongue 31 is connected to the connecting mechanism 20, a buffer groove 32 having a movement direction identical to that of the locking tongue 31 is disposed at a rear portion of the locking tongue 31, a latch block 21 of the connecting mechanism 20 is embedded in the buffer groove 32, a restoring spring 33 having a movement direction identical to that of the locking tongue 31 is disposed at a rear portion of the locking tongue 31, and when the locking tongue 31 is in a locked state, the latch block 21 of the connecting mechanism 20 is abutted against a rear end of the buffer groove 32. According to the lock mechanism, a user controls the main lock mechanism to act, so that the action of the connecting mechanism 20 is controlled, the action of the lock head mechanism is further controlled, the safety door is unlocked, due to the design of the buffer groove 32 and the fixture block 21, the automatic locking can be realized under the control of the door closer, the specific action principle is that when the safety door is closed, the wedge-shaped lock tongue 31 is used for compressing the lock tongue to retract into the door, due to the existence of the buffer groove 32, the fixture block 21 of the connecting mechanism 20 cannot block the action of the lock tongue, and when the lock tongue is aligned with a lock hole in a door frame, the lock tongue extends out under the pushing of the recovery spring, so that the locking purpose is realized; here and in the claims the rear end of the buffer groove 32 is directed away from the wedge-shaped part of the bolt.

Known from fig. 2, the dashpot 32 is the bar hole, and the major axis in this bar hole is unanimous with spring bolt 31 direction of motion, coupling mechanism 20's fixture block 21 is for inlaying the card post in this bar hole, when the spring bolt is compressed to return, the card post slides forward in the bar hole to do not influence the spring bolt action, and when the spring bolt stretches out, the card post slides backward in the bar hole, finally contradicts in the rear end in the bar hole, does not influence coupling mechanism action pulling spring bolt action, unblanks. Similarly, the buffer groove 32 may be an open groove located on the side surface of the lock tongue 31, and the latch 21 of the connection mechanism 20 may be a claw-shaped latch, and a claw portion of the claw-shaped latch is embedded in the open groove (not shown).
