Figure 4 , 11 When the lock tongue drive assembly drives the lock tongue 50 to rotate, the support portion 500 of the lock tongue 50 is at least partially retracted from the mouth portion 30 into the vertical rod 3, and is disengaged from the bottom of the limit portion 110 of the active top corner 11, and the locking mechanism is unlocked, such as Fig. 9 ,12 shown.

[0050] In this embodiment: the bolt drive assembly provides two implementation modes:

[0051] Method 1: If Figure 4 , 9 As shown: the bolt drive assembly includes a sliding member 51 slidably arranged in the vertical rod 3, a traction rope 52 connected to the sliding member 51 at one end, a sliding member reset member 54 (spring) connected between the vertical rod 3 and the sliding member 51 to give the sliding member 51 sliding recovery elastic force, and the other end of the traction rope 52 is connected to the rotating member 41. A guide slope 510 is arranged on the sliding member 51, and the lower end of the bolt 5 is against the guide slope 510. When the traction rope 52 is pulled to drive the sliding member 51 to slide downward (Z direction), the lower end of the bolt 50 slides relative to the guide slope 510 and rotates; when the traction rope 52 is released, the sliding member 51 is reset upward under the action of the sliding member reset member 54, and the bolt 50 is rotated and reset under the action of the bolt reset member 53.

[0052] Method 2: If Fig.11 , 12 As shown, the lock tongue driving assembly includes a traction rope 52, one end of which is connected to the lower end of the lock tongue 50, and the other end of which is connected to the rotating member 41. When the traction rope 52 is pulled, the lock tongue 50 is directly driven to rotate; when the traction rope 52 is released, the lock tongue 50 rotates and resets under the action of the lock tongue reset member 53.

[0053] The traction ropes 52 are all passed through the bottom support rods 20 and the vertical rods 3. A roller 55 is provided on the extension path of the traction rope 52, which is specifically provided in the foot of the bed 22. The traction rope 52 is passed around the outer peripheral surface of the roller 55. Figure 5 shown.

[0054] In addition, the playbed further comprises a plurality of legs 6, one end of each leg 6 being rotatably connected to the base 21, and the other end of each leg 6 forming a supporting end, and the plurality of legs 6 can be rotated downward and brought together.

[0055] When the playbed needs to be folded up, the handle 42 is pulled upward, and the handle 41 drives the rotating member 42 to rotate around the rotating seat 40 along the track of the arrow R, as shown in FIG. Fig.17 , 18 As shown, the rotating member 42 compresses the unlocking reset member 43 and pulls the traction rope 52, so that the traction rope 52 moves along Figure 6As shown in the figure, the traction rope 52 pulls the sliding member 51 to drive the lock tongue 50 or directly drives the lock tongue 50, so that the lock tongue 50 rotates and compresses the lock tongue reset member 53. When the lock tongue 50 is retracted to the point where its support portion 500 is disengaged from the limit portion 110 below the movable top corner 11, the unlocking operation is completed. At this time, the movable top corner 11 is linked to the upper enclosure rod 10 and moves along the vertical rod 3 under the action of its own weight. Fig.14 The W arrow in the figure moves downward, and the handle 41 continues to move upward, and the movable top corner 11 and the upper surrounding rod 10 move downward accordingly, and the bottom support rod 20 and the support leg 6 move along Fig.14 The vertical rod 3 and the bed foot 22 move upward in the direction of the Y arrow in FIG. Fig.14 Move in the direction of the arrow F until the playbed is folded into a bundle. Fig.19 shown.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
