[0046] Optionally, the first rod 31 and the second rod 32 are hollow tubes. For example, the first rod 31 and the second rod 32 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 first rod 31 and the second rod 32 can also be solid rods.
[0047] In one embodiment, referring to Figure 4 The crib further comprises two support assemblies 40. Each of the two support assemblies 40 is disposed between the two side frames 10 and spaced apart along the second direction. One end of the support assembly 40 is connected to one of the side frames 10, and the other end of the support assembly 40 is connected to the other side frame 10.
[0048] Optionally, the support assembly 40 is detachably connected to the two side frames 10. In this way, the crib can be disassembled, which is beneficial to reducing the packaging volume of the crib and reducing the transportation cost.
[0049] Further, referring to Figure 4 The support assembly 40 comprises a third rod 41 and a fourth rod 42. 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 comprises a folding joint 60. The folding joint 60 is disposed between the second end of the fourth rod 42 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 60. In this way, the folding and unfolding of the support assembly 40 can be achieved.
[0052] In order to prevent the crib from being mistakenly folded during use and causing harm to the infant, 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 4The crib further comprises a joint lock assembly 50. The joint lock assembly 50 is arranged at the second end of the first rod member 31 and the second end of the second rod member 32, and the first rod member 31 is rotatably connected with the second rod member 32 through the joint lock assembly 50.
[0054] The joint lock assembly 50 has a locked state and an unlocked state, as shown in Figure 1 When the crib is unfolded and the joint lock assembly 50 is in the locked state, the first rod member 31 and the second rod member 32 are coaxially arranged, and the first rod member 31 and the second rod member 32 are both fixed relative to the side frame 10. As shown in Figure 6 and Figure 8 The first rod member 31 and the second rod member 32 can both rotate relative to the side frame 10, so that the crib can be folded.
[0055] In this embodiment, as shown in Figure 1 Two joint lock assemblies 50 are arranged. One of the joint lock assemblies 50 is arranged at the second end of one of the first rod members 31 and the second end of the corresponding second rod member 32, and the other joint lock assembly 50 is arranged at the second end of the other first rod member 31 and the second end of the corresponding second rod member 32.
[0056] In one embodiment, the crib further comprises an unlocking assembly 70. The unlocking assembly 70 comprises an operating member 71 and a linkage member 72. The operating member 71 is reversibly arranged on the side frame 10, and the operating member 71 is connected with the joint lock assembly 50 through the linkage member 72. The unlocking assembly 70 is used to control the joint lock assembly 50 to switch from the locked state to the unlocked state.
[0057] If the crib needs to be folded, the operating member 71 is reversibly turned outward, and the operating member 71 drives the joint lock assembly 50 to act through the linkage member 72, so that the joint lock assembly 50 switches from the locked state to the unlocked state. When the joint lock assembly 50 is unlocked, the second end of the first rod member 31 and the second end of the second rod member 32 rotate downward under the action of gravity, so that the first end of the first rod member 31 and the first end of the second rod member 32 are folded toward the middle. Then, an external force is applied to the folding joint 60, and the second end of the third rod member 41 and the second end of the fourth rod member 42 are reversibly turned upward, so that the first end of the third rod member 41 and the first end of the fourth rod member 42 are folded toward the middle. In the folding process, the two side frames 10 are close to each other to be attached to each other. In this way, the overall folding of the crib can be realized, which is conducive to reducing the volume of the crib and reducing the space required for storing the crib. In addition, the folding steps of the crib can be simplified, and the folding efficiency can be improved.
[0058] In one embodiment, as shown in Figure 1 and Figure 2 The operating member 71 is an unlocking wrench, and the unlocking wrench is reversibly arranged on the side frame 10. Alternatively, the unlocking wrench is reversibly arranged on the first connecting member 13.
[0059] Optionally, the unlocking wrench is reversibly arranged on one side of one of the side frames 10 away from the other side frame 10. When unlocking, the unlocking wrench is reversed towards the side away from the other side frame 10, which is convenient for operation and can avoid the baby from triggering the unlocking wrench by mistake.
[0060] In one embodiment, the linkage 72 is a linkage rope. Of course, in other embodiments, the linkage 72 can also be other linkage structures, which are not limited in this regard.
[0061] Optionally, the linkage rope comprises 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.
[0062] In this embodiment, two linkages 72 are arranged, and the two linkages 72 are both connected with the operating member 71. One end of one of the linkages 72 away from the operating member 71 is connected with one of the joint lock assemblies 50, and one end of the other linkage 72 away from the operating member 71 is connected with the other joint lock assembly 50. In this way, when the operating member 71 is reversed outward, the operating member 71 can drive the two joint lock assemblies 50 to move synchronously, so as to realize the synchronous unlocking of the two joint lock assemblies 50.
[0063] In one embodiment, the unlocking assembly 70 further comprises 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.
[0064] Optionally, the first elastic reset member is a torsion spring. One end of the torsion spring is connected with the unlocking wrench, and the other end of the torsion spring is connected with the side frame 10.
[0065] When unlocking, an external force is applied to the unlocking wrench, the unlocking wrench is reversed towards the side away from the other side frame 10, 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 reverse to reset.
[0066] In one embodiment, referring to Figure 4 and Figure 5 , the joint lock assembly 50 comprises a lock tongue 51 and a lock plug 52. The lock tongue 51 is movably arranged at the second end of the first rod member 31, and the lock plug 52 is arranged at the second end of the second rod member 32. One end of the linkage 72 away from the operating member 71 is connected with the lock tongue 51.
[0067] Referring to Figure 4 and Figure 5In the locked state, the lock plug 52 is overlapped on the lock tongue 51. The linkage 72 can drive the lock tongue 51 to move away from the lock plug 52, so as to switch the joint lock assembly 50 from the locked state to the unlocked state. Refer to Figure 7 In the unlocked state, the lock tongue 51 is separated from the lock plug 52.
[0068] When the baby bed is unfolded, the joint lock assembly 50 is in the locked state, and the lock plug 52 is overlapped on the lock tongue 51. When the baby bed is used, the operation member 71 is turned outward, and the operation member 71 drives the lock tongue 51 to move away from the lock plug 52 through the linkage 72, so that the lock tongue 51 is separated from the lock plug 52, and the joint lock assembly 50 is unlocked. After the joint lock assembly 50 is unlocked, the second end of the first rod member 31 and the second end of the second rod member 32 move downward under the action of their own gravity, so that one end of the first rod member 31 and the first end of the second rod member 32 are folded to the middle.
[0069] In an embodiment, refer to Figure 3 The joint lock assembly 50 further comprises a housing 53. The housing 53 is sleeved on the second end of the first rod member 31 and the second end of the second rod member 32. The second end of the first rod member 31 and the second end of the second rod member 32 are rotatably connected with the housing 53.
[0070] Specifically, refer 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 31 is provided with a second connecting hole 311, and the lock 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 31. The first connecting hole 538, the second connecting hole 311 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 311 and the avoiding hole 512. In this way, when the joint lock assembly 50 is switched between the locked state and the unlocked state, the lock tongue 51 moves along the length direction of the first rod member 31, and because the avoiding hole 512 of the lock tongue 51 is in strip shape, the strip-shaped avoiding hole 512 can accommodate the first rotating connecting member.
[0071] Specifically, refer to Figure 3 , Figure 5 and Figure 7 The housing 53 is further provided with a third connecting hole 539. The second end of the second rod member 32 is provided with a fourth connecting hole 321, and the lock plug 52 is provided with a fifth connecting hole 521. The third connecting hole 539, the fourth connecting hole 321 and the fifth connecting hole 521 are in communication, and a second rotating connecting member is arranged in the third connecting hole 539, the fourth connecting hole 321 and the fifth connecting hole 521.
[0072] In an embodiment, refer to Figure 3The shell 53 is provided with a limiting hole 535 and an arc hole 536 in communication with the limiting hole 535. The limiting hole 535 is arranged corresponding to the position between the first rod member 31 and the second rod member 32, and the arc hole 536 is arranged corresponding to the second end of the first rod member 31.
[0073] 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 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 hole 536.
[0074] 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 72, the sliding member 54 slides from the limiting hole 535 to the arc hole 536 and moves in the arc hole 536 in a direction away from the limiting hole 535. In this way, when the sliding member 54 slides in the arc 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 31 can be driven to rotate downward.
[0075] If the baby crib needs to be unfolded, the sliding member 54 moves in the arc 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 30 is fixed relative to the side frame 10.
[0076] In addition, under the cooperation of the arc 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.
[0077] Further, referring to Figure 3 , the arc hole 536 takes the first connecting hole 538 as the center. In this way, the first rod member 31 rotates around the first connecting hole 538, avoiding interference of the arc hole 536 with the rotation of the first rod member 31, and ensuring the smoothness of the rotation of the first rod member 31.
[0078] In another embodiment, referring to Figure 11 , Figure 12 and Figure 13 , the shell 53 is provided with a plug hole 537.
