TECHNICAL FIELD

[0001] The present application relates to the technical field of baby products, and particularly relates to a portable and foldable lightweight baby crib. BACKGROUND

[0002] With the increase of travel probability, users pay more and more attention to the portability of baby cribs. In the related art, the baby crib is relatively heavy and cannot be folded, so that the baby crib occupies too much space and is inconvenient to carry. SUMMARY

[0003] The present application provides a portable and foldable lightweight baby crib, which can solve the technical problems in the related art.

[0004] The present application provides a portable and foldable lightweight baby crib, which comprises a baby crib frame, a baby basket, a diaper table and a miscellaneous rack. The baby basket, the diaper table and the miscellaneous rack are detachably connected to the baby crib frame. The baby crib frame has a folded state and an unfolded state. The baby crib frame comprises two first connecting rods, the two first connecting rods being oppositely arranged; four connecting pieces, the four connecting pieces being respectively connected to two ends of the two first connecting rods; two second connecting rods, two ends of the two second connecting rods being respectively connected to the four connecting pieces, the two second connecting rods and the two first connecting rods forming a quadrilateral bed frame; each second connecting rod comprising two short connecting rods and a hinge unit, each short connecting rod having a first end and a second end, the first ends of the two short connecting rods of the same second connecting rod being hingedly connected through the hinge unit, the second ends of the four short connecting rods being respectively hingedly connected to the four connecting pieces; and four supporting feet, the four supporting feet being respectively hingedly connected to the four connecting pieces. When the baby crib frame is switched from the unfolded state to the folded state, the two hinge units are close to each other, the two first connecting rods are close to each other, and the two supporting feet located at two ends of any first connecting rod are rotated and close to the first connecting rod.

[0005] The portable and foldable lightweight baby crib provided by the present application can be folded from the unfolded state to the folded state, so that the baby crib can be conveniently folded. In the folded state, the first connecting rod, the short connecting rod and the supporting foot can be close to each other and substantially in a parallel state, so that the baby crib frame occupies a very small volume in the folded state and is convenient to carry. In addition, the baby basket, the diaper table and the miscellaneous rack are detachably connected to the baby crib frame, the baby basket, the diaper table and the miscellaneous rack can be selectively carried and conveniently installed on the baby crib frame according to the use requirement, the structure of the baby crib is simplified, so that the lightweight and portability are realized. When needed, the baby basket, the diaper table and the miscellaneous rack can be simultaneously connected to the baby crib frame, so that the baby crib can cope with more use scenarios.

[0006] In some example embodiments, each of the articulated units comprises: an articulated plate, the first ends of the two short connecting rods of the same second connecting rod being articulated with the articulated plate; two connecting plates, the two connecting plates being connected with the first ends of the two short connecting rods of the same second connecting rod respectively, and opposite ends of the two connecting plates being provided with limiting grooves; and a blocking piece, the blocking piece being slidable to simultaneously enter or exit the two limiting grooves, the articulated unit being in a locked state when the blocking piece simultaneously enters the two limiting grooves, and the articulated unit being in a released state when the blocking piece simultaneously exits the two limiting grooves.

[0007] Based on the above-mentioned embodiments, the articulated unit has two states of release and lock, and the switching of release and lock can be conveniently and quickly completed by sliding the blocking piece. When the articulated unit is released, the folding of the crib frame is facilitated, and when the crib frame is in an unfolded state, the locking of the articulated unit can ensure the stability of the crib frame.

[0008] In some example embodiments, the articulated plate comprises: an upper plate; a lower plate, the lower plate being provided with a through hole for the blocking piece to pass through, the first ends of the short connecting rods being articulated with the upper plate and / or the lower plate; and a side plate connecting the upper plate and the lower plate, the side plate being located on the side of the short connecting rod facing the other articulated unit, and the side plate being rotatable to abut against the connecting plate to limit the rotation range of the short connecting rod.

[0009] Based on the above-mentioned embodiments, the short connecting rod can only rotate towards the inside, and cannot rotate towards the outside, so that when the crib frame is folded, the short connecting rod can only be folded inward, and cannot be folded outward, which can not only ensure the directionality of each folding, but also ensure that the crib frame occupies a smaller volume after being folded.

[0010] In some example embodiments, each of the articulated units further comprises an articulated operating piece; the top end and the bottom end of the blocking piece are respectively bent and extended to form an upper bent plate and a lower bent plate, the extension directions of the upper bent plate and the lower bent plate being perpendicular to the moving direction of the blocking piece; the upper plate is located above the upper bent plate to limit the sliding stroke of the upper bent plate, and the lower bent plate is clamped to the articulated operating piece and abuts against the articulated operating piece, so that the articulated operating piece can drive the blocking piece to slide.

[0011] Based on the above-mentioned embodiments, the upper plate can limit the sliding of the upper bent plate, so that the blocking piece can stop sliding when simultaneously exiting the two limiting grooves. The lower bent plate can be clamped to the articulated operating piece, so that the fixation between the two is more firm and reliable, and is not easy to fall off.

[0012] In some example embodiments, each of the articulated units further comprises a housing having a sliding hole, and the upper bending plate is slidingly arranged in the sliding hole.

[0013] Based on the above-mentioned embodiments, the sliding hole on the housing can guide the sliding of the upper bending plate, so that the sliding of the blocking piece is more stable.

[0014] In some example embodiments, the connecting plate is bent and extended to form an extension plate, the extension direction of the extension plate is the same as the moving direction of the blocking piece, and the extension plate can be rotated to abut against the blocking piece to limit the rotation range of the short connecting rod.

[0015] Based on the above-mentioned embodiments, the extension plate can interfere with the rotation range of the short connecting rod, so as to control the rotation amplitude of the short connecting rod when rotating inwardly, and make the short connecting rod rotate to a preset folding angle.

[0016] In some example embodiments, the connecting piece comprises a housing connected to the first connecting rod and articulated with the second end of the short connecting rod and the support leg, a release long hole and a locking long hole in communication with the release long hole are formed in the housing, the extension direction of the locking long hole is parallel to the extension direction of the support leg, and the release long hole extends from the locking long hole and is arranged away from the support leg; a locking piece is slidingly connected to the release long hole or the locking long hole, the locking piece abuts against the support leg when sliding to the locking long hole to block the rotation of the support leg relative to the housing, and the locking piece releases the abutment with the support leg when sliding to the release long hole, so that the support leg can rotate relative to the housing to be folded.

[0017] Based on the above-mentioned embodiments, the locking piece can lock or release the support leg, so as to facilitate the folding of the support leg or ensure the stability of the support leg when being unfolded. Meanwhile, when the locking piece is located in the locking long hole, the locking piece has self-locking property, and the user cannot slide the locking piece to the release long hole by rotating the support leg.

[0018] In some example embodiments, each of the connecting pieces further comprises a resilient piece clamped between the locking piece and the housing, and the resilient piece applies force to the locking piece, so that the locking piece always has a tendency to slide into the locking long hole.

[0019] Based on the above-mentioned embodiments, under the condition of no external force, the locking piece is always in the locked state, so as to ensure that the support leg will not be suddenly folded, and further improve the safety of the crib frame when being used.

[0020] In some example embodiments, the infant basket comprises a basket frame and a first locking mechanism arranged on the basket frame. The first locking mechanism comprises a first fastening member arranged on the basket frame, which can be arranged on the upper surface and the side surface of the short connecting rod; and a first locking member rotatably arranged on the first fastening member. When the first locking member is rotated to the side of the lower surface of the short connecting rod, the first locking mechanism locks the basket frame and the short connecting rod. When the first locking member is rotated to the side of the side surface of the short connecting rod, the first locking mechanism releases the lock of the basket frame and the short connecting rod.

[0021] According to the above-mentioned embodiments, the basket frame and the crib frame can be locked or released by rotating the first locking member, thereby improving the safety of the basket frame in use.

[0022] In some example embodiments, the first locking mechanism further comprises a locking operation member slidably arranged on the first fastening member and in transmission connection with the first locking member. The locking operation member has a locking position and a release position. When the locking operation member is in the locking position, the first locking member is in the locked state. When the locking operation member is in the release position, the first locking member is in the released state. A return spring is arranged between the locking operation member and the first fastening member, and exerts a force on the locking operation member, so that the locking operation member always has a tendency to slide to the locking position, and the first locking member always has a tendency to rotate to the side of the lower surface of the short connecting rod. A torsion spring has two force arms respectively connected to the first fastening member and the first locking member, and exerts a force on the first locking member. When the locking operation member slides to the release position, the torsion spring drives the first locking member to rotate to the side of the side surface of the short connecting rod.

[0023] According to the above-mentioned embodiments, the return spring continuously exerts a force on the locking operation member. In the absence of external force, the basket frame remains locked with the short connecting rod, thereby ensuring that the infant basket cannot fall off the crib frame, and increasing the safety of the infant basket in use. When it is necessary to separate the infant basket from the crib frame, the locking operation member only needs to be pressed. When the locking operation member is released, the infant basket is relocked, and the operation is relatively convenient.

[0024] In some example embodiments, the first locking mechanism further comprises a pressing block arranged on the locking operation member. The locking operation member drives the pressing block to slide, so that the pressing block drives the first locking member to rotate. The pressing block is integrally formed with the locking operation member.

[0025] Based on the above embodiment, the pushing and rotating mode of the pressing block on the locking operation piece is reliable and durable. The pressing block is integrally formed with the locking operation piece, which can reduce the manufacturing steps and production cost.

[0026] In some exemplary embodiments, the diaper table comprises a table frame and a second locking mechanism arranged on the table frame. The second locking mechanism comprises a second fastening piece arranged on the table frame, which can be arranged on the upper surface and side surface of the short connecting rod; and a second locking piece arranged on the second fastening piece. When the second locking piece is rotated to the side of the lower surface of the short connecting rod, the second locking mechanism locks the table frame and the short connecting rod. When the second locking piece is rotated to the side of the side surface of the short connecting rod, the second locking mechanism releases the lock of the table frame and the short connecting rod.

[0027] Based on the above embodiment, the diaper table and the crib frame can be locked or released by rotating the second locking piece, thereby improving the safety of the diaper table during use. At the same time, due to the fewer components of the second locking mechanism and the compact structure, not only the cost can be saved, but also the weight of the diaper table is reduced, making the diaper table convenient to carry.

[0028] In some exemplary embodiments, the storage rack comprises a hook that can be hung on the first connecting rod, and a rack body connected with the hook. When the hook is hung on the first connecting rod, the rack body abuts against the connecting piece.

[0029] Based on the above embodiment, the storage rack is connected with the crib frame through the hook, and the hook has a simple structure and good durability and is not easy to be damaged. The hook can be conveniently hung and taken, and even a single hand can easily complete the hanging and taking. The abutment of the rack body and the connecting piece can increase the stability of the storage rack when hung.

[0030] In some exemplary embodiments, two rollers are arranged at the end of two adjacent support feet away from the connecting piece.

[0031] Based on the above embodiment, two support feet have rollers, and the other two support feet do not have rollers, so that the crib can be fixedly placed and conveniently moved.

[0032] In some example embodiments, one of the support legs is a hollow structure, a through hole is formed in a side wall of the hollow structure, and the crib frame further comprises a reinforcing member, the reinforcing member comprising: a winding roller arranged on an inner wall of the hollow structure; a steel wire rope, one end of the steel wire rope being connected to the winding roller, the winding roller being used for winding the steel wire rope; a hook, the other end of the steel wire rope passing through the through hole and being connected to the hook; the steel wire rope being wound around the other three support legs after passing out of the through hole, the hook being connected to the hollow structure, and the steel wire rope limiting the four support legs.

[0033] Based on the above-mentioned embodiments, the steel wire rope can be wound around the four support legs to limit the four support legs, thereby preventing the four support legs from rotating outward due to excessive force and increasing the firmness of the crib frame.

[0034] In some example embodiments, the size of the hook is greater than the size of the through hole.

[0035] Based on the above-mentioned embodiments, the hook will not fall into the through hole, which is convenient to use.

[0036] In some example embodiments, an outer wall of the other three support legs is provided with a groove for limiting the steel wire rope.

[0037] Based on the above-mentioned embodiments, the groove limits the steel wire rope, thereby preventing the steel wire rope from slipping on the outer wall of the support leg and increasing the stability of the steel wire rope during use.

[0038] In some example embodiments, the reinforcing member further comprises a hanging ring arranged on an outer wall of the support leg with the through hole, and the hook can be hung on the hanging ring.

[0039] Based on the above-mentioned embodiments, compared with the hook being directly hung on the support leg, the connection between the hook and the hanging ring is more stable, the risk of the hook falling off is reduced, and the safety of the hook during use is increased.

[0040] In some example embodiments, the portable and foldable lightweight crib of any of the above-mentioned embodiments further comprises a covering member, the covering member and the crib frame jointly defining a space for the infant to move.

[0041] Based on the above-mentioned embodiments, the covering member can limit the movement range of the infant, thereby preventing the infant from climbing out of the crib and causing accidents. At the same time, since the covering member is usually soft in texture, it can provide a certain protection effect for the infant. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0063] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0064] As Figure 1As shown, the portable foldable lightweight baby crib 10 provided by the embodiments of the present application comprises a baby crib frame 100 and baby crib accessories, the baby crib accessories comprising a baby basket 210, a diaper table 220 and a sundry rack 230. The baby basket 210, the diaper table 220 and the sundry rack 230 are detachably connected to the baby crib frame 100. The baby crib frame 100 has a folded state and an unfolded state.

[0065] The baby crib frame 100 comprises two first connecting rods 110, four connecting pieces 120, two second connecting rods 130 and four supporting legs 140.

[0066] The two first connecting rods 110 are oppositely arranged, and the first connecting rod 110 can be a round pipe or a square pipe, etc.

[0067] The connecting piece 120 is used to connect the first connecting rod 110, the second connecting rod 130 and the supporting leg 140, and the four connecting pieces 120 are respectively connected to the two ends of the two first connecting rods 110.

[0068] The two second connecting rods 130 are oppositely arranged, and the second connecting rod 130 can be a round pipe or a square pipe, etc. The two second connecting rods 130 and the two first connecting rods 110 enclose a quadrilateral bed frame. Each second connecting rod 130 comprises two short connecting rods 131 and a hinge unit 132. Each short connecting rod 131 has a first end and a second end. The first ends of the two short connecting rods 131 of the same second connecting rod 130 are hingedly connected through the hinge unit 132, and the second ends of the four short connecting rods 131 are respectively hingedly connected to the four connecting pieces 120.

[0069] The four supporting legs 140 are used to support the quadrilateral bed frame, and the four supporting legs 140 are respectively hingedly connected to the four connecting pieces 120.

[0070] The baby crib frame 100 has a folded state and an unfolded state. The baby crib frame 100 can be switched from the unfolded state as shown in FIG. 1 to the folded state as shown in FIG. 2. Figure 2 Figures 3-4 When the baby crib frame 100 is switched from the unfolded state as shown in FIG. 1 to the folded state as shown in FIG. 2, the first end of the short connecting rod 131 rotates relative to the hinge unit 132, the second end of the short connecting rod 131 rotates relative to the connecting piece 120, the two short connecting rods 131 of the same second connecting rod 130 are mutually attached, the two hinge units 132 are mutually close, the two first connecting rods 110 are mutually close, and the two supporting legs 140 located at the two ends of any first connecting rod 110 rotate and are close to the first connecting rod 110.

[0071] ​In summary, the baby crib frame 100 in the folded state, the first connecting rod 110, the short connecting rod 131, the support leg 140 can be close to each other, and substantially in parallel, so that the baby crib frame 100 in the folded state only needs to occupy a small volume, convenient to carry.

[0072] As Figures 5-7 shown, in some embodiments, each of the hinge units 132 includes a hinge plate 1321, two connecting plates 1322, a blocking piece 1323 and a hinge operating piece 1324. The material of the hinge plate 1321, the connecting plate 1322 and the blocking piece 1323 is preferably metal material to improve durability. The first end of the two short connecting rods 131 of the same second connecting rod 130 is hingedly connected with the hinge plate 1321. Specifically, the hinge plate 1321 and the short connecting rod 131 can be connected by a rotating shaft, and the rotating shaft passes through the first end of the hinge plate 1321 and the short connecting rod 131 to realize the hinge connection of the hinge plate 1321 and the short connecting rod 131. The two connecting plates 1322 are respectively connected with the first end of the two short connecting rods 131 of the same second connecting rod 130, and the connecting plate 1322 can rotate with the corresponding short connecting rod 131. The opposite ends of the two connecting plates 1322 are respectively provided with a limiting groove 132a. The blocking piece 1323 is simultaneously and slidably arranged in the two limiting grooves 132a, and the blocking piece 1323 can be simultaneously located in the two limiting grooves 132a or simultaneously exit the two limiting grooves 132a. When the blocking piece 1323 is simultaneously located in the two limiting grooves 132a, the blocking piece 1323 interferes with the rotation of the two connecting plates 1322, and the two connecting plates 1322 cannot rotate, at which time the hinge unit 132 is in a locked state. When the blocking piece 1323 is simultaneously located outside the two limiting grooves 132a, the blocking piece 1323 does not interfere with the rotation of the two connecting plates 1322, and the two connecting plates 1322 can rotate, at which time the hinge unit 132 is in an unlocked state. The hinge operating piece 1324 is in transmission connection with the blocking piece 1323, and the hinge operating piece 1324 is used to drive the blocking piece 1323 to slide to drive the hinge unit 132 to switch between the locked state and the unlocked state.

[0073] Continuing to refer to Figure 7In some embodiments, the hinged plate 1321 comprises an upper plate 1325, a lower plate 1326 and a side plate 1327. The lower plate 1325 is provided with a through hole 132b for the blocking piece 1323 to pass through, and the first end of the short connecting rod 131 is hinged to the upper plate 1325 and / or the lower plate 1326. The hinging of the short connecting rod 131 to both the upper plate 1325 and the lower plate 1326 can enhance the stability during rotation. The side plate 1327 connects the upper plate 1325 and the lower plate 1326, and is located on the inner side of the short connecting rod 131, i.e. on the side of the short connecting rod 131 facing the other hinged unit 132. The side plate 1327 abuts against the connecting plate 1322 to limit the rotation range of the short connecting rod 131, so that the two hinged units 132 can only move closer to each other during rotation, but cannot move away from each other.

[0074] With reference to Figures 7-8 In some embodiments, each hinged unit 132 further comprises a hinged operating member 1324 for driving the blocking piece 1323 to move up and down. The top end and the bottom end of the blocking piece 1323 are respectively bent to form an upper bent plate 1328 and a lower bent plate 1329, and the extension direction of the upper bent plate 1328 and the lower bent plate 1329 is perpendicular to the moving direction of the blocking piece 1323. The upper plate 1325 is located above the upper bent plate 1328, and the upper bent plate 1328 cannot continue to slide upward when it abuts against the upper plate 1325, so that the upper plate 1325 can limit the sliding stroke of the upper bent plate 1328. The lower bent plate 1329 is clamped to the hinged operating member 1324 and abuts against the hinged operating member 1324, so that the hinged operating member 1324 can drive the blocking piece 1323 to slide. The clamping of the lower bent plate 1329 to the hinged operating member 1324 is not easy to loosen, and is convenient for assembly.

[0075] With reference to Figure 9 Each hinged unit further comprises a housing 1331 provided with a sliding hole for guiding. The upper bent plate 1328 is slidably arranged in the sliding hole, and the size of the sliding hole is matched with the size of the upper bent plate 1328, so that the upper bent plate 1328 can stably slide in the sliding hole, and the blocking piece 1323 can stably slide.

[0076] With reference to Figure 7 The connecting plate 1322 is bent to form an extension plate 1330, and the extension direction of the extension plate 1330 is the same as the moving direction of the blocking piece 1323. The extension plate 1330 can abut against the blocking piece 1323 to limit the rotation range of the short connecting rod 131, so as to prevent the short connecting rod 131 from rotating excessively and protect the short connecting rod 131.

[0077] like Figures 10-11 As shown, in some embodiments, each of the connectors 120 includes a housing 121 and a locking member 122. The housing 121 is connected to the first connecting rod 110 and hinged to the second end of the corresponding short connecting rod 131 and the support leg 140. The housing 121 has a release elongated hole 121a and a locking elongated hole 121b communicating with the release elongated hole 121a. The locking member 122 is slidably connected to the release elongated hole 121a or the locking elongated hole 121b. When the locking member 122 slides to the locking elongated hole 121b, it abuts against the corresponding support leg 140 to prevent the corresponding support leg 140 from rotating relative to the housing 121. When the locking member 122 is located in the release elongated hole 121a, it releases the abutment against the corresponding support leg 140, allowing the corresponding support leg 140 to rotate relative to the housing and fold.

[0078] The extending direction of the locking elongated hole 121b is parallel to the extending direction of the corresponding support foot 140. When the locking member 122 is located in the locking elongated hole 121b, the locking member 122 abuts against the support foot 140, and the locking member 122 has self-locking properties, preventing the locking member 122 from sliding by rotating the support foot 140. The releasing elongated hole 121a extends from the locking elongated hole 121b and is located away from the corresponding support foot 140. When the locking member 122 is released, it needs to overcome the force of the elastic member to push the locking member 122 to slide into the releasing elongated hole 121a. When the locking member 122 is released, the elastic member can drive the locking member 122 to slide from the releasing elongated hole 121a to the locking elongated hole 121b. For ease of operation, the connecting member 120 may also include a locking operation member 123, which is connected to the locking member 122 and is used to push the locking member 122 to slide.

[0079] In some embodiments, the connector 120 may further include an elastic element (not shown in the figure), which is engaged between the locking member 122 and the housing 121. The elastic element applies force to the locking member 122, so that the locking member 122 always has a tendency to slide into the locking elongated hole 121b, that is, the locking member 122 is always located in the locking elongated hole 121b when no external force is applied, thereby keeping the locking member 122 in a locked state.

[0080] like Figure 10As shown, in some embodiments, the infant basket 210 comprises a basket frame 211 and a first locking mechanism 300, which is arranged on the basket frame 211. The number of the first locking mechanism 300 is two, and two first locking mechanisms 300 are arranged on one pair of opposite sides of the basket frame 211. The other pair of opposite sides of the basket frame 211 is an arc-shaped rod, which has strong bearing capacity. It can be understood that the other pair of opposite sides of the basket frame 211 can be a telescopic sleeve rod, which can be adjusted in length, so that the basket frame 211 can be connected to the two first connecting rods 110 and the two second connecting rods 130 to meet the needs of infants of different heights.

[0081] As shown, Figures 13-15 The first locking mechanism 300 comprises a first clamping member 310 and a first locking member 320. The first clamping member 310 is arranged on the basket frame 211, and has a clamping groove 310a.

The return spring 340 is arranged between the locking operation member 330 and the first clasp 310, and the return spring 340 applies a force to the locking operation member 330, so that the locking operation member 330 always has a tendency to slide to the locking position, that is, the locking operation member 330 is always in the locking position without external force. Further, the first locking member 320 always has a tendency to rotate to the lower surface side of the short connecting rod 131, and the first locking mechanism 300 is kept locked.

[0084] As shown in Figure 14 In some embodiments, the first locking mechanism 300 further comprises a pressing block 331 arranged on the locking operation member 330. The pressing block 331 can be a triangular protrusion. When the locking operation member 330 drives the pressing block 331 to move up and down, the protrusion and the surface of the first locking member 320 in contact with each other move left and right relative to the first locking member 320, so as to drive the first locking member 320 to rotate. The pressing block 331 can be integrally formed with the locking operation member 330 to facilitate manufacturing.

[0085] Continuing to refer to Figures 13-15 In some embodiments, the first locking mechanism 300 further comprises a torsion spring 350, and two force arms of the torsion spring 350 abut against the first clasp 310 and the first locking member 320, respectively. The torsion spring 350 acts on the first locking member 320, and when the locking operation member 330 is in the release position under the action of external force, the torsion spring 350 drives the first locking member 320 to rotate to the side surface side of the short connecting rod 131, so that the first locking mechanism 300 is released.

[0086] In summary, the baby basket 210 of the present embodiment can be locked and released from the baby crib frame 100 by rotating the first locking member 320, which is conducive to the quick assembly and disassembly of the baby crib frame 100, and can also avoid the baby basket 210 from falling off the baby crib frame 100. The baby basket 210 is used for the sleep of infants and young children, and the infants and young children will lie in the baby basket 210 for a long time. The return spring 340 keeps the baby basket 210 in continuous locking connection with the baby crib frame 100, which can prevent the baby basket 210 from falling accidentally and improve the safety of the baby basket 210 in use.

[0087] As shown in Figures 16-17 In some embodiments, the diaper table 220 includes a table frame 221 and a second locking mechanism 222, the second locking mechanism 222 is arranged on the table frame 221, and the second locking mechanism 222 includes a second buckling member 2221 and a second locking member 2222. The second buckling member 2221 is arranged on the table frame 221, and the second buckling member 2221 can be arranged on the upper surface and the side surface of the short connecting rod 131. The second locking member 2222 is arranged on the second buckling member 2221, and when the second locking member 2222 is rotated to the side of the lower surface of the short connecting rod 131, the second locking mechanism 222 locks the table frame 2221 and the short connecting rod 131; when the second locking member 2222 is rotated to the side of the side surface of the short connecting rod 131, the second locking mechanism 222 releases the table frame and the short connecting rod 131. Since the diaper table 220 is used for a short time each time, the baby will not lie on it for a long time, so the second locking mechanism 222 can be designed as a structure for manual locking or releasing, which can save costs and reduce the weight of the diaper table 220, so that the diaper table 220 is convenient to carry.

[0088] As shown in Figure 17 In some embodiments, the miscellaneous rack 230 includes a hook 231 and a rack body 232, the rack body 232 is connected with the hook 231, and the hook 231 can be hung on the first connecting rod 110. When the hook 231 is hung on the first connecting rod 110, the rack body 232 abuts against the connecting member 120 to increase the stability of the miscellaneous rack 230. The miscellaneous rack 230 is preferably made of plastic, which is light and has good durability. The miscellaneous rack 230 can place clothes, diapers, bottles, etc.

[0089] Continuing to refer to Figure 17In some embodiments, the baby crib frame 100 further comprises two rollers 160, which are arranged at the ends of two adjacent support legs 140 away from the connecting member 120. It is understood that the length of the two support legs 140 with the rollers 160 is preferably shorter than the length of the two support legs 140 without the rollers 160, so that the total length of the two support legs 140 with the rollers 160 is equal to the length of the two support legs 140 without the rollers 160, thereby ensuring the horizontality of the baby crib frame 100 after being unfolded.

[0090] In some embodiments, the portable foldable lightweight baby crib 10 of any of the above embodiments further comprises a cover member, which together with the baby crib frame 100 defines a space for the baby to play in. For example, the cover member can cover the bottom and sides of the baby crib frame 100, and if necessary, the top of the baby crib frame 100, so that the baby cannot climb out of the portable foldable lightweight baby crib 10, thereby improving safety. The cover member can be various knitted products, such as non-woven fabric. The material and style of the cover member can be changed as needed to adapt to different seasons.

[0091] As shown in Figures 18-19 In some embodiments, one of the support legs 140 is a hollow structure, and a through hole 140a is formed in the side wall of the hollow support leg 140. The baby crib frame 100 further comprises a reinforcing member, which comprises a roller, a steel wire rope 151, and a hook 152. The roller is arranged on the inner wall of the hollow support leg 140. One end of the steel wire rope 151 is connected to the roller, which is used to wind the steel wire rope 151. When the steel wire rope 151 is pulled out, the resistance of the roller needs to be overcome, and when the steel wire rope 151 is released, the roller automatically winds up the steel wire rope 151. The other end of the steel wire rope 151 passes through the through hole 140a and is connected to the hook 152. When it is necessary to reinforce the support leg 140, the hook 152 is pulled to pull out the steel wire rope 151, and after the steel wire rope 151 passes out of the through hole 140a, the steel wire rope 151 is wound around the other three support legs 140, and then the hook 152 is connected to the hollow support leg 140, and the steel wire rope 151 surrounds the four support legs 140 once, thereby limiting the four support legs 140 and preventing the support legs 140 from rotating outward. The size of the hook 152 is preferably larger than the size of the through hole 140a, so that the hook 152 cannot fall into the through hole 140a.

[0092] With reference to Figure 19In some embodiments, the outer wall of the other three support feet 140 is provided with a groove 140b for limiting the steel wire rope 151 to avoid slipping on the outer wall of the support foot 140. In order to facilitate the connection of the hook 152 with the hollow structure of the support foot 140, the reinforcing member can further comprise a hanging ring 153 provided on the outer wall of the support foot 140 with the through hole 140a, and the hook 152 can be hung on the hanging ring 153.
