The first end of the third rod 41 is rotatably connected to one of the side frames 10, the first end of the fourth rod 42 is rotatably connected to the other side frame 10, and the second end of the third rod 41 is rotatably connected to the second end of the fourth rod 42.

[0050] Optionally, the third rod 41 and the fourth rod 42 are hollow tubes. For example, the third rod 41 and the fourth rod 42 are both hollow circular tubes. In this way, the weight of the crib can be reduced, and the cost can also be reduced. Of course, in other embodiments, the third rod 41 and the fourth rod 42 can also be solid rods.

[0051] Further, the crib further includes a folding joint 30. The folding joint 30 is provided in pairs, and each folding joint 30 is provided corresponding to the support rod assembly 40. The folding joint 30 is disposed between the second end of the third rod 41 and the second end of the fourth rod 42, and the third rod 41 is rotatably connected to the fourth rod 42 through the folding joint 30. In this way, the folding and folding of the support rod assembly 40 can be achieved.

[0052] In order to prevent the crib from being misfolded and injuring the baby during use, the crib further has a locking function for locking the unfolded state and an unlocking function for releasing the locked state.

[0053] In one embodiment, referring to Figure 1 and Figure 4 , the crib further comprises a joint lock assembly 50. Two joint lock assemblies 50 are provided, one for each of the two rail assemblies 20. The joint lock assembly 50 is provided at the second end of the first bar 21 and the second end of the second bar 22, and the first bar 21 is rotatably connected to the second bar 22 via the joint lock assembly 50. The joint lock assembly 50 has a locked state and an unlocked state. When the crib is unfolded, the joint lock assembly 50 is in the locked state, and the first bar 21 and the second bar 22 are fixed to the side frame 10. In the unlocked state, the first bar 21 and the second bar 22 can rotate relative to the side frame 10, so that the crib can be folded.

[0054] When the crib is unfolded, referring to Figure 1 and Figure 10 , in each rail assembly 20, the first bar 21 and the second bar 22 are coaxially arranged, and at the same time the joint lock assembly 50 is in the locked state, and the first bar 21 and the second bar 22 are fixed to the side frame 10.

[0055] In one embodiment, the crib further comprises an unlocking assembly 70. Two unlocking assemblies 70 are provided, one for each of the two joint lock assemblies 50, and the unlocking assembly 70 is used to control the joint lock assembly 50 connected thereto to switch from the locked state to the unlocked state.

[0056] If the crib needs to be folded, referring to Figure 4 and Figure 6 , an external force acts on both unlocking assemblies 70 at the same time, one of which drives the joint lock assembly 50 connected thereto to unlock, and the other of which drives the joint lock assembly 50 connected thereto to unlock, so that the joint lock assembly 50 can switch from the locked state to the unlocked state. It can be understood that when both joint lock assemblies 50 are in the unlocked state, the crib can be folded and folded, and when one joint lock assembly 50 is in the unlocked state and the other joint lock assembly 50 is in the locked state, the crib cannot be folded and folded. In this way, it can be prevented that the crib is triggered by mistake and causes the crib to be folded, ensuring the safety of the crib in use.

[0057] In one embodiment, referring to Figure 4 one of the unlocking assemblies 70 is provided on one of the side frames 10, and the other of the unlocking assemblies 70 is provided on the other of the side frames 10.

[0058] Of course, in other embodiments, the two unlocking assemblies 70 can also be provided on the same side frame 10.

[0059] In one embodiment, referring to Figure 1 and Figure 2The two unlocking assemblies 70 each include an operating member 71 and a linkage member 72. The operating member 71 is arranged on the side frame 10, and the operating member 71 is connected with the joint lock assembly 50 through the linkage member 72. If the baby crib needs to be folded, an external force is applied to the operating member 71, the operating member 71 drives the joint lock assembly 50 to act through the linkage member 72, so that the joint lock assembly 50 is switched from the locked state to the unlocked state. In this way, the joint lock assembly 50 is conveniently unlocked, and the unlocking efficiency is improved.

[0060] In one embodiment, referring to Figure 2 The operating member 71 is an unlocking wrench which is reversibly arranged on the side frame 10. Alternatively, the unlocking wrench is reversibly arranged on the first connecting member 13.

[0061] Alternatively, referring to Figure 1 and Figure 2 The unlocking wrench is reversibly arranged on one side of one of the side frames 10 which faces away from the other side frame 10. When unlocking, the unlocking wrench is flipped in the direction away from the side frame 10 opposite to it, which is convenient for operation and avoids the baby from accidentally triggering the unlocking wrench.

[0062] In one embodiment, the linkage member 72 is a linkage rope. Of course, in other embodiments, the linkage member 72 can also be other linkage structures, which are not limited in this regard.

[0063] Alternatively, the linkage rope includes a steel wire rope and a protective sleeve. The length of the steel wire rope is less than the length of the protective sleeve, the steel wire rope is movably arranged in the protective sleeve, and the steel wire rope can move along the length direction of the protective sleeve relative to the protective sleeve. One end of the steel wire rope is connected with the operating member 71, and the other end of the steel wire rope is connected with the joint lock assembly 50. In this way, the steel wire rope plays a linkage role, and the protective sleeve plays a positioning role.

[0064] In one embodiment, the unlocking assembly 70 further includes a first elastic reset member. The first elastic reset member is connected with the unlocking wrench and the side frame 10, and is used to drive the unlocking wrench to reset.

[0065] Alternatively, the first elastic reset member is a torsional spring. One end of the torsional spring is connected with the unlocking wrench, and the other end of the torsional spring is connected with the side frame 10.

[0066] When unlocking, an external force is applied to the unlocking wrench, the unlocking wrench is flipped in the direction away from the side frame 10 opposite to it, and the first elastic reset member is gradually stretched. After the unlocking is completed, the external force applied to the unlocking wrench is removed, and the first elastic reset member is gradually stretched to drive the unlocking wrench to be flipped in the reverse direction to reset.

[0067] In one embodiment, referring to Figure 4 and Figure 5The joint locking assembly 50 comprises a locking tongue 51 and a locking plug 52. The locking tongue 51 is movably arranged at the second end of the first rod member 21, and the locking plug 52 is arranged at the second end of the second rod member 22. The linkage 72 is connected to the locking tongue 51 at an end away from the operating member 71.

[0068] Referring to Figure 4 and Figure 5 , in the locked state, the locking plug 52 overlaps the locking tongue 51. The linkage 72 can drive the locking tongue 51 to move away from the locking plug 52, so as to switch the joint locking assembly 50 from the locked state to the unlocked state. Referring to Figure 7 , in the unlocked state, the locking tongue 51 is separated from the locking plug 52.

[0069] When the baby bed is unfolded and the joint locking assembly 50 is in the locked state, the first rod member 21 and the second rod member 22 are coaxially arranged, and the locking plug 52 overlaps the locking tongue 51.

[0070] If the baby bed needs to be folded, the operating member 71 is turned outward, the operating member 71 drives the locking tongue 51 to move away from the locking plug 52 through the linkage 72, so that the locking tongue 51 is separated from the locking plug 52, and the joint locking assembly 50 is unlocked. After the joint locking assembly 50 is unlocked, the second end of the first rod member 21 and the second end of the second rod member 22 move downward under the action of their own gravity, so that the first end of the first rod member 21 and the first end of the second rod member 22 are folded to the middle.

[0071] In an embodiment, referring to Figure 3 , the joint locking assembly 50 further comprises a housing 53. The housing 53 is sleeved on the second end of the first rod member 21 and the second end of the second rod member 22. The second end of the first rod member 21 and the second end of the second rod member 22 are rotatably connected to the housing 53.

[0072] Specifically, referring to Figure 3 , Figure 5 and Figure 7 , the housing 53 is provided with a first connecting hole 538, the second end of the first rod member 21 is provided with a second connecting hole 211, and the locking tongue 51 is provided with an avoiding hole 512. The avoiding hole 512 is in strip shape and extends along the length direction of the first rod member 21. The first connecting hole 538, the second connecting hole 211 and the avoiding hole 512 are in communication, and a first rotating connecting member is arranged in the first connecting hole 538, the second connecting hole 211 and the avoiding hole 512. In this way, when the joint locking assembly 50 is switched between the locked state and the unlocked state, the locking tongue 51 moves along the length direction of the first rod member 21, and because the avoiding hole 512 of the locking tongue 51 is in strip shape, the strip-shaped avoiding hole 512 can accommodate the first rotating connecting member.

[0073] Specifically, referring to Figure 3 , Figure 5 andFigure 7 The shell 53 is further provided with a third connecting hole 539. The second end of the second rod member 22 is provided with a fourth connecting hole 221, and the lock plug 52 is provided with a fifth connecting hole 521. The third connecting hole 539, the fourth connecting hole 221 and the fifth connecting hole 521 are in communication, and the third connecting hole 539, the fourth connecting hole 221 and the fifth connecting hole 521 are provided with a second rotating connecting member.

[0074] In one embodiment, referring to Figure 3 The shell 53 is provided with a limiting hole 535 and an arc-shaped hole 536 in communication with the limiting hole 535. The limiting hole 535 is arranged corresponding to the position between the first rod member 21 and the second rod member 22, and the arc-shaped hole 536 is arranged corresponding to the second end of the first rod member 21.

[0075] Further, the joint lock assembly 50 further comprises a sliding member 54 arranged on the lock tongue 51. In the locked state, the sliding member 54 is arranged in the limiting hole 535. The sliding member 54 can move in the arc-shaped hole 536 in a direction away from the limiting hole 535, so as to switch the joint lock assembly 50 from the locked state to the unlocked state. In the unlocked state, the sliding member 54 is located in the arc-shaped hole 536.

[0076] If the baby crib needs to be folded, the operating member 71 is turned outward, and the operating member 71 drives the lock tongue 51 to move away from the lock plug 52, that is, under the driving of the linkage member 72, the sliding member 54 slides from the limiting hole 535 to the arc-shaped hole 536 and moves in the arc-shaped hole 536 in a direction away from the limiting hole 535. In this way, when the sliding member 54 slides in the arc-shaped hole 536, on the one hand, the joint lock assembly 50 can be switched from the locked state to the unlocked state, and on the other hand, the second end of the first rod member 21 can be driven to rotate downward.

[0077] If the baby crib needs to be unfolded, the sliding member 54 moves in the arc-shaped hole 536 in a direction close to the limiting hole 535 until the sliding member 54 slides into the limiting hole 535. The hole wall of the limiting hole 535 limits the sliding member 54, so that the lock tongue 51 is fixed relative to the shell 53, and at the same time, the lock plug 52 is lapped on the lock tongue 51, so that the surrounding rod assembly 20 is fixed relative to the side frame 10.

[0078] In addition, under the cooperation of the arc-shaped hole 536 and the sliding member 54, the movement of the sliding member 54 is guided, the stability of the movement of the sliding member 54 is improved, and the smoothness of unfolding and folding of the baby crib is ensured.

[0079] Further, referring to Figure 3 The arc-shaped hole 536 takes the first connecting hole 538 as the center. In this way, the first rod member 21 rotates around the first connecting hole 538, avoiding interference of the arc-shaped hole 536 with the rotation of the first rod member 21, and ensuring the smoothness of the rotation of the first rod member 21.

[0080] In another embodiment, referring to Figure 11 , Figure 12 and Figure 13 , the housing 53 is provided with a socket 537. The joint lock assembly 50 further comprises a limiting member 55, which is movably arranged in the socket 537 or detachably arranged in the socket 537. The lock tongue 51 is provided with a limiting slot 511.

[0081] In the locked state, the limiting member 55 is in limiting cooperation with the limiting slot 511 to limit the movement of the lock tongue 51 relative to the first rod member 21. In the unlocked state, the limiting member 55 is separated from the limiting slot 511.

[0082] If the baby crib needs to be folded, the limiting member 55 is pulled outward so that the limiting member 55 is separated from the limiting slot 511 to release the limiting of the lock tongue 51, so that the second ends of the first rod member 21 and the second rod member 22 are turned downward under the action of their own gravity, and the first ends of the first rod member 21 and the second rod member 22 are folded towards the middle.
