Application method
When the door is locked, the cam 2 keeps the opening 16 on the cam 2 towards the insertion opening 15 of the mounting base 1 under the action of the torsion spring; when the door hook is inserted into the insertion opening 15 of the mounting base 1, the door hook enters the opening 16 of the cam 2, so that the cam 2 can be driven to rotate.
When the cam 2 rotates, the latch 3 arranged above the cam 2 and in sliding contact with the cam 2 slides along the outer wall surface of the cam 2, and when the cam 2 is driven to rotate by the door hook for the first time, the hook 4 on the latch 3 firstly moves along the extending direction of the first guide surface 9 and reaches the first blocking surface 10 after the hook 4 passes the first guide surface 9; at this time, when the cam 2 is released from the driving of the door hook, the cam 2 is driven by the torsion spring to rotate reversely, the hook 4 slides in the direction of the second guide surface 11 against the first stopper surface 10 and reaches the lock surface 12 along the second guide surface 11, and the cam 2 is hooked and locked by the lock surface 12.
When the door hook driving cam 2 is rotated for the second time, the cam 2 rotates forward, the hook 4 hooked on the locking surface 12 slides toward the third guide surface 14 along the second blocking surface 13, after the hook 4 passes the second blocking surface 13, the hook 4 reaches the bottom end of the third guide surface 14, at this time, when the door hook is released from driving the cam 2, the cam 2 rotates backward under the driving of the torsion spring, and the hook 4 slides along the third guide surface 14, so that the hook locking of the cam 2 is released.
When the door is opened using the child lock function in a state where the cam 2 is locked by the locker 3, that is, when the door is pushed outward from the inside: first, the cam 2 is pulled outward by the door hook to reverse, and at this time, since the latch 3 is in a hook-locked state with the cam 2, the latch 3 slides toward the cam 2. Hasp 3 is at the slip in-process, and the lug 7 and the extension board 8 contact of its lower surface extend the board 8 along the gliding in-process of lug 7, with 4 end liftings of trip of hasp 3 to the hook of 4 pairs of cams 2 of quick removal trip. When the extension plate 8 moves to the other side of the projection 7, because the surfaces of the projection 7 facing to the front and the rear are both inclined surfaces, when the latch 3 returns to the return position, the extension plate 8 can smoothly return to the front of the projection 7 without being caught at the rear.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
