Technical Field

[0001] The utility model relates to the technical field of children's beds, in particular to a collapsible bed frame and a children's bed. Background Art

[0002] A children's bed can be used for children to lie and sleep or play. For the convenience of carrying and storing, the children's bed is generally set to be collapsible. When in use, the children's bed is unfolded, and when not in use, the children's bed is folded. The structure of the children's bed mainly includes a bed frame and a cloth cover. During the use process, the bed frame is collapsible, and the cloth cover is folded along with the folding of the bed frame.

[0003] The existing collapsible bed frame is troublesome to fold, with many operation steps; moreover, when the bed frame is completely folded, it has a large volume and requires a large storage space. Summary of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the utility model is to provide a collapsible bed frame and a children's bed that are convenient to fold and unfold, occupy a small space after folding, and are convenient to carry.

[0005] The technical solution adopted by the utility model to solve its technical problem is to provide a collapsible bed frame, which has an unfolded state and a folded state, and includes:

[0006] An upper surrounding frame, including two relatively arranged first surrounding rods and two relatively arranged second surrounding rods. Two ends of one of the first surrounding rods are respectively rotatably connected to one ends of the two second surrounding rods, and two ends of the other first surrounding rod are respectively rotatably connected to the other ends of the two second surrounding rods; the first surrounding rod includes a first rod, a second rod, a first locking member and an unlocking member. The first rod and the second rod are rotatably connected, the first locking member is arranged between the first rod and the second rod, and can lock the first rod and the second rod; the unlocking member can unlock the first locking member;

[0007] A plurality of support legs, one ends of the plurality of support legs are rotatably connected to the upper surrounding frame, and the other ends of the plurality of support legs are support ends; a second locking member is arranged between the support legs and the upper surrounding frame, and the second locking member can lock the support legs;

[0008] After driving the unlocking member to unlock the first locking member, the first rod and the second rod can rotate inwards to fold, and during the folding process, the first rod and the second rod can drive the second locking member to unlock so as to fold the support legs.

[0009] Further, a first locking groove is arranged on the support leg. When the second locking member locks into the first locking groove, the support leg is locked;

[0010] When the second locking member disengages from the first locking groove, the support leg is unlocked.

[0011] Further, the second locking member and the first surrounding rod are connected by a wire. One end of the wire is connected to the second locking member, and the other end of the wire is connected to the first surrounding rod.

[0012] When the first surrounding rod rotates and folds, the first surrounding rod pulls the second locking member through the wire, unlocking the second locking member, and the support leg can rotate and fold.

[0013] Further, a first spring is provided between the support leg and the upper surrounding frame. One end of the first spring abuts against the second locking member, and the other end of the first spring abuts against the upper surrounding frame. The elastic force of the first spring makes the second locking member tend to move in its locking direction.

[0014] When the first surrounding rod pulls the second locking member through the wire to unlock the second locking member, the first spring is compressed.

[0015] Further, a receiving groove is provided on the second locking member, and the first spring is located in the receiving groove.

[0016] Further, a second locking groove is provided on the second rod member, and the first locking member can be locked into the second locking groove to lock the first rod member and the second rod member.

[0017] The unlocking member can push against the first locking member to disengage the first locking member from the second locking groove, thereby unlocking the first rod member and the second rod member.

[0018] Further, a second spring is provided between the first rod member and the first locking member. One end of the second spring abuts against the first locking member, and the other end of the second spring abuts against the first rod member. The elastic force of the second spring makes the first locking member tend to move in its locking direction.

[0019] When the unlocking member drives the first locking member to unlock, the second spring is compressed.

[0020] Further, a third spring is provided between the second rod member and the unlocking member. One end of the third spring abuts against the second rod member, and the other end of the third spring abuts against the unlocking member.

[0021] When the unlocking member is pressed to unlock the first locking member, the third spring is compressed. When the unlocking member is released, the third spring drives the unlocking member to reset.

[0022] Further, when the bed frame switches from the unfolded state to the folded state: the two first enclosing rods rotate inwards and fold, and the two second enclosing rods approach each other; the plurality of support legs rotate and fold, and their support ends approach the upper enclosing frame;

[0023] The length of the first enclosing rod is greater than the length of the second enclosing rod.

[0024] The technical solution adopted by the present utility model to solve its technical problems is to further propose a children's bed, including the foldable bed frame described above.

[0025] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0026] In the present utility model, when the unlocking member is pressed to unlock the first locking member, relative rotation can occur between the first rod and the second rod, and the upper enclosing frame can be folded. During the folding process, the first rod and the second rod will drive the second locking member to unlock, so that the support legs can rotate relative to the upper enclosing frame to fold the support legs to the upper enclosing frame, thereby completing the overall folding of the bed frame. During the folding process, only by pressing the unlocking member can one-key folding be achieved, without the need for multiple unlocking operations. The folding operation is simple. Moreover, after the bed frame is folded, it is small in size, occupies little space, and is convenient for storage and carrying. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0044] As Figures 1 - 9 shown, a foldable bed frame according to this embodiment is optimally applied to a children's bed, and the children's bed folds as the bed frame folds. That is, the bed frame has an unfolded state and a folded state. When in use, the bed frame is switched to the unfolded state (as shown in Figure 1 ), and when not in use, the bed frame is switched to the folded state (as shown in Figures 7 - 9 ), reducing the space it occupies, thereby ensuring convenient storage and carrying.

[0045] The foldable bed frame of this embodiment mainly includes: an upper surrounding frame 1 and a plurality of support legs 2 rotatably connected to the upper surrounding frame 1. When the bed frame is switched from the unfolded state to the folded state: the two first surrounding rods 11 rotate inwards and fold, and the two second surrounding rods 12 approach each other; the plurality of support legs 2 rotate and fold, and their supporting ends approach the upper surrounding frame 1.

[0046] As Figures 1 - 3 shown, the upper surrounding frame 1 includes two first surrounding rods 11 arranged oppositely and two second surrounding rods 12 arranged oppositely. Among them, the length of the first surrounding rod 11 is greater than that of the second surrounding rod 12. During the folding process, the first surrounding rod 11 can be folded in the middle. To ensure that the occupied space after folding is small, the length of the first surrounding rod 11 is approximately twice the length of the second surrounding rod 12. One end of each of the two ends of one first surrounding rod 11 is rotatably connected to one end of the two second surrounding rods 12, and the two ends of the other first surrounding rod 11 are respectively rotatably connected to the other ends of the two second surrounding rods 12. Therefore, the two first surrounding rods 11 and the two second surrounding rods 12 are connected end to end to form a rectangular frame structure, that is, the upper surrounding frame 1. The first surrounding rod 11 includes a first rod member 111, a second rod member 112, a first locking member 113 and an unlocking member 114. The first rod member 111 and the second rod member 112 are rotatably connected. The first locking member 113 is arranged between the first rod member 111 and the second rod member 112 and can lock the first rod member 111 and the second rod member 112; the unlocking member 114 can unlock the first locking member 113. It should be noted that both ends of the first rod member 111 have connecting joints, both ends of the second rod member 112 have connecting joints, and both ends of the second surrounding rod 12 also have connecting joints. Each surrounding rod and rod member are rotatably connected through the connecting joints at their ends. After the first locking member 113 locks the first rod member 111 and the second rod member 112, the first rod member 111 and the second rod member 112 cannot be folded, ensuring the structural stability during unfolding. Only when the unlocking member 114 unlocks the first locking member 113 can the first rod member 111 and the second rod member 112 be folded relative to each other.

[0047] One end of multiple support legs 2 is rotatably connected to the upper perimeter frame 1. Specifically, the upper end of the support leg 2 has a connecting joint, and the support leg 2 is rotatably connected to the upper perimeter frame 1 through the connecting joint at its end. The other end of the multiple support legs 2 is a support end, that is, the lower ends of the multiple support legs 2 are support ends. The multiple support ends can support on the ground to support the entire bed frame, that is, to support the crib. The support ends of the support legs 2 can be provided with foot pads to increase the friction with the ground, ensure reliable support and prevent slipping. A second locking member 20 is provided between the support leg 2 and the upper perimeter frame 1, and the second locking member 20 can lock the support leg 2. When the second locking member 20 locks the support leg 2, the support leg 2 cannot be folded. This ensures the support stability of the support leg 2 when the bed frame is unfolded and in use. During the use process, when the user drives the unlocking member 114 to unlock the first locking member 113, the first rod 111 and the second rod 112 can rotate inward and fold. During the folding process, the first rod 111 and the second rod 112 can drive the second locking member 20 to unlock, so as to fold the support leg 2. After the upper frame is folded and the multiple support legs 2 are folded, the entire bed frame is folded.

[0048] Specifically, a first locking groove 21 is provided on the support leg 2. The first locking groove 21 is located at the connecting joint at the upper end of the support leg 2. When the second locking member 20 is locked into the first locking groove 21, the support leg 2 is locked. At this time, the support leg 2 cannot rotate relative to the upper perimeter frame 1, that is, it cannot be rotated and folded. When the second locking member 20 disengages from the first locking groove 21, the support leg 2 is unlocked. After the support leg 2 is unlocked, it can rotate and fold relative to the upper perimeter frame 1. Among them, the second locking member 20 is connected to the first perimeter rod 11 through a wire 22. One end of the wire 22 is connected to the second locking member 20, and the other end of the wire 22 is connected to the first perimeter rod 11. The first perimeter rod 11 can pull the second locking member 20 through the wire 22 to unlock the second locking member 20. And, a first spring 23 is provided between the support leg 2 and the upper perimeter frame 1. One end of the first spring 23 abuts against the second locking member 20, and the other end of the first spring 23 abuts against the upper perimeter frame 1. The elastic force of the first spring 23 makes the second locking member 20 tend to move in its locking direction. Under the action of the first spring 23, when the second locking member 20 is in the locked state, it will not disengage from the first locking groove 21, ensuring reliable locking. When the first perimeter rod 11 pulls the second locking member 20 through the wire 22 to unlock the second locking member 20, the first spring 23 is compressed. When the bed frame is switched to the unfolded state, under the action of the first spring 23, the second locking member 20 can be automatically locked into the first locking groove 21, which is convenient to use.

[0049] Preferably, a receiving groove 201 is provided on the second locking member 20, and the first spring 23 is located in the receiving groove 201, that is, the first spring 23 does not need to occupy additional installation space, and the structure is compact.

[0050] More specifically, a second locking groove 112A is provided on the second rod member 112. The first locking member 113 can be locked into the second locking groove 112A to lock the first rod member 111 and the second rod member 112. At this time, a part of the first locking member 113 is located in the first rod member 111, and the other part is located in the second rod member 112, so that the first rod member 111 and the second rod member 112 cannot rotate relative to each other. The unlocking member 114 can push against the first locking member 113 to disengage the first locking member 113 from the second locking groove 112A, so as to unlock the first rod member 111 and the second rod member 112, and the two can be rotated and folded. Wherein, a second spring 115 is provided between the first rod member 111 and the first locking member 113. One end of the second spring 115 abuts against the first locking member 113, and the other end of the second spring 115 abuts against the first rod member 111. The elastic force of the second spring 115 causes the first locking member 113 to tend to move in its locking direction. When the unlocking member 114 drives the first locking member 113 to unlock, the second spring 115 is compressed. Similarly, the setting of the second spring 115 ensures the structural stability when the first locking member 113 is locked, so that the first locking member 113 will not accidentally disengage from the second locking groove 112A, and when the bed frame is unfolded, the acting force of the second spring 115 can cause the first locking member 113 to automatically lock into the second locking groove 112A, which is convenient to use.

[0051] Wherein, a third spring 116 is provided between the second rod member 112 and the unlocking member 114. One end of the third spring 116 abuts against the second rod member 112, and the other end of the third spring 116 abuts against the unlocking member 114. When the unlocking member 114 is pressed to unlock the first locking member 113, the third spring 116 is compressed, and the unlocking member 114 is released. The third spring 116 drives the unlocking member 114 to reset, that is, the function of the third spring 116 is to reset the unlocking member 114, which is convenient for unlocking next time.

[0052] Such as Figure 1 and Figures 4 - 9 As shown, during the use process, when the bed frame needs to be folded, the operator presses the unlocking member 114. The unlocking member 114 pushes against the first locking member 113, so that the first locking member 113 moves upward and disengages from the second locking groove 112A. The first locking member 113 is unlocked, and the first rod member 111 and the second rod member 112 can rotate relative to each other and fold, and the upper frame is folded (such as Figure 5 shown state). And during the folding process of the upper surrounding frame 1, both the first rod member 111 and the second rod member 112 will rotate, so that both the first rod member 111 and the second rod member 112 pull the second locking member 20 through the wire 22, so that the second locking members 20 at the four support legs 2 all move upward and disengage from the first locking groove 21. The second locking member 20 is unlocked, and the support legs 2 are rotated upward, and the four support legs 2 can be folded (such as Figures 7 - 9 shown), and the folding of the bed frame is completed.

[0053] In this solution, during the process of folding the bed frame, the operator only needs to press the unlocking member 114 to achieve one-key folding of the bed frame. There is no need to perform multiple unlocking actions subsequently. The folding action is simple, and the overall volume of the folded bed frame is small, occupying little space, and is convenient for storage and carrying.
