Referring to fig. 6 and 7, when it is required to fold the cage, the locking assembly between the third side frame 300 and the first side frame 100 is unlocked, so that the two sets of third side frames 300 rotate downward around the third rotation center line Z and are folded above the bottom frame 400 in a stacked manner.

Referring to fig. 4 and 8, the operating handle 12 is then grasped to rotate the operating member 1 counterclockwise, causing all the sliders 4 to slide inwardly along the unlocking slide slots 11, so that the traction cable 5 pulls each locking member 2 away from and out of the mating member 3, and the locking mechanism is unlocked. And the guide member 71 on the first side frame 100 can slide downwards along the guide slot 72, and when the first side frame 100 slides to the bottom, the first side frame 100, the two sets of third side frames 300 and the bottom frame 400 are stacked together from top to bottom. It should be noted that once the locking member 2 is disengaged from the mating member 3, the operating member 1 can be released, the operating member 1 is reset by the force of the second elastic member 6, but the locking member 2 abuts against the frame of the second side frame 200 without being inserted into the mating member 3, so that the first side frame 100 can continue to slide up and down.

As shown in fig. 9, finally, the second side frames 200 on both sides are respectively turned around the second rotation center line Y to be folded toward the upper side of the first side frame 100, and the height of the second rotation center line Y is higher than the stacking height of the first side frame 100, the two sets of third side frames 300, and the bottom frame 400, so that the second side frames 200 can rotate without interference, and the two sets of second side frames 200 are located at the same height above the first side frame 100.

When the pet cage needs to be unfolded, the above steps are operated in a reverse direction, wherein when the first side frame 100 slides upwards along the second side frame 200 to the top, the locking member 2 corresponds to the matching member 3, and the two are automatically matched and locked under the action of the first elastic member 21, so that the operation member 1 does not need to be rotated manually, and the pet cage is very convenient.

In the present embodiment, since each set of locking mechanisms is relatively independent, even if there is a set of locking members 2 that do not correspond to the mating member 3, normal locking of the other locking mechanisms is not affected, and the reliability of the locking mechanisms is high.
