Description

Technical Field

[0001] This utility model relates to the technical field of children's furniture, specifically a safe baby crib. Background Technology

[0002] Infants, especially those between 0 and 12 months, spend most of their time lying down to sleep and rest. However, adults often need to go out, and when infants are taken out of the home, it's difficult to provide them with a comfortable environment for lying down or moving around. Therefore, existing technology offers a portable crib, which, compared to traditional cribs, is easy to carry and takes up little space. When not in use, the crib can be folded away for storage, saving considerable space. Existing portable cribs have a frame that is quickly assembled via interlocking. However, during assembly, improper actions such as insufficient user strength or inaccurate positioning can easily lead to incomplete frame assembly, resulting in the frame's instability failing to meet the product's pre-set requirements. This reduces the crib's structural load-bearing capacity, affecting its stability and causing it to wobble during use, potentially harming the infant inside. Utility Model Content

[0003] The present invention aims to provide a safe baby crib that can improve the safety of baby crib during use.

[0004] This utility model provides the following basic solution:

[0005] A safe baby crib includes four support rods, two short frame rods, and two sets of long frame rod assemblies. The top of each support rod is provided with a movable connector. The ends of the short frame rods are fixedly connected to the movable connectors, and the ends of the long frame rod assemblies are movably connected to the movable connectors. The two short frame rods and the two sets of long frame rod assemblies can be arranged to form a parallelogram.

[0006] The long frame rod assembly includes two short rods and a locking member hinged to the ends of the two short rods. The locking member includes a locking block. One end of each of the two short rods is provided with a locking part. The locking block can abut against the locking part and can move along the contact surface with the locking part. The direction of movement of the locking block is perpendicular to the length direction of the short rod.

[0007] Furthermore, it also includes a bed bag with a top opening, the top of which wraps around the short and long frame rod assemblies, and the bottom of the bed bag has four connecting straps that connect to the support rods in a one-to-one correspondence.

[0008] Furthermore, the locking component also includes a connecting frame, and the locking parts of the locking block and the short rod are both located inside the connecting frame. The bottom of the locking block is provided with a connecting block, which passes through the connecting frame.

[0009] Furthermore, a force-applying plate is provided at the end of the connecting block away from the locking block.

[0010] Furthermore, all connecting frames are U-shaped frames, with the end of the short rod rotatably connected to the connecting frame. The opening of the connecting frame faces the other connecting frame, and the side of the connecting frame away from the other connecting frame has a notch for the end of the short rod to rotate.

[0011] Furthermore, the movable connector includes a movable sleeve that is detachably connected to the support rod. The top of the movable sleeve is provided with a fixed cylinder facing the short frame rod. The end of the short frame rod is located inside the fixed cylinder and is fixedly connected to the fixed cylinder.

[0012] Furthermore, the top of the movable sleeve is also provided with a U-shaped connecting plate. The length direction of the U-shaped connecting plate is perpendicular to the axial direction of the fixed sleeve. The opening of the U-shaped connecting plate faces the fixed sleeve located on the same movable sleeve. The end of the short rod away from the locking element is located inside the U-shaped connecting plate and is rotatably connected to the U-shaped connecting plate.

[0013] Furthermore, a locking block is provided inside the U-shaped connecting plate. The short rod can be inserted into the U-shaped connecting plate through the opening of the U-shaped connecting plate along the locking block. The locking block can prevent the short rod from coming out of the U-shaped connecting plate.

[0014] Furthermore, each support rod has a slotted hole on its periphery, and the connecting strap passes through the slotted hole on the side away from the bed bag. A blocking block is provided on the side of the connecting strap that passes through the slotted hole.

[0015] Furthermore, each support rod has a fixing block at its bottom, and each fixing block has a through hole. Each connecting strip has an adhesive component at its bottom, which passes through the through hole and connects to the fixing block.

[0016] The beneficial effects of the basic scheme:

[0017] 1. In this design, the support rods, short frame rods, and long frame rods form the main body of the crib, providing stable support. The locking blocks and locking parts remain engaged during use, limiting their position and preventing rotation, thus preventing the long frame rod assembly from wobbling and improving the crib's structural stability. The crib bag provides space for the infant to sleep and move, and allows the infant to be placed inside through the top opening. The crib bag prevents the infant from falling out of the main body composed of the support rods, short frame rods, and long frame rods. This design, through the support rods, short frame rods, and long frame rods, enhances the structural stability of the crib, and combined with the crib bag, improves safety during use.

[0018] 2. In this design, the connecting block connects the locking block to the outside environment. Combined with the force-applying plate, it facilitates the application of force to the locking block, thereby changing its position. The locking block, in conjunction with the U-shaped connecting plate, allows for state switching between the locking block and the locking part through the application of force. For example, when the locking block abuts against the locking part, the short rods in the same long frame assembly are limited. At this time, the two short rods in the same long frame assembly are on the same straight line. Applying force to the force-applying plate changes the position of the connecting block, allowing the short rods to move. This changes the relative position of the two short rods in the same long frame assembly, shortening the distance between them. This allows the short and long frame assemblies to be folded and stored, reducing the floor space required. Using this design, the combination of locking components and movable connecting components enables the folding and storage of the crib, making it easy to store. Attached Figure Description

At the same time, in this embodiment, the locking part 6 and the top and bottom of the U-shaped frame are provided with pivot holes, and the pivot holes are provided with pins to realize the rotatable connection between the locking part 6 and the locking block 4.

[0029] The top of the locking part 6 has a first groove that connects to the side wall, and the bottom of the first groove has a second groove that connects to the side wall. The locking parts 6 of the locking block 4 and the short rod 3 are both located within the connecting frame 5. The locking block 4 can abut against the locking part 6, and the locking block 4 can move along the contact surface with the locking part 6. The moving direction of the locking block 4 is perpendicular to the length direction of the short rod 3.

[0030] An elastic element is provided between the locking block 4 and the connecting frame 5. A spring groove is provided on the top of the locking block 4, and another spring groove is provided on the corresponding position on the U-shaped frame. The two ends of the elastic element are respectively placed in the two spring grooves. In this embodiment, the elastic element is a compression spring, which is limited by the spring groove. When the two short rods 3 of the same long frame rod assembly are in the same straight line, the locking block 4 abuts against the side wall of the second groove of the locking part 6. When the long frame rod assembly is folded and stored, the bottom of the locking block 4 abuts against the bottom of the first groove of the locking part 6.

[0031] The bottom of the locking block 4 is provided with a connecting block, which passes through the connecting frame 5. A force-applying hole is provided at the bottom of the U-shaped frame for the connecting block to pass through. A force-applying plate 7 is provided at the end of the connecting block away from the locking block 4, and the force-applying plate 7 is parallel to the bottom of the U-shaped frame. In this embodiment, the connecting block and the force-applying plate 7 are integrally formed, and the locking block 4 is fixedly connected to the connecting block by screws. In other embodiments, the locking block 4, the connecting block, and the force-applying plate 7 are integrally formed. The force-applying plate 7 increases the effective area, making it easier to apply force and change the position of the locking block 4.

[0032] As attached Figure 3As shown, each movable connector includes a movable sleeve 8 detachably connected to the support rod 1. The top of each movable sleeve 8 is provided with a fixed sleeve 9 and a U-shaped connecting plate 10. In this embodiment, the movable sleeve 8, fixed sleeve 9, and U-shaped connecting plate 10 are integrally formed. The fixed sleeve 9 faces the short frame rod 2, and the end of the short frame rod 2 is located inside the fixed sleeve 9 and fixedly connected to it. In this embodiment, the short frame rod 2 is inserted into the fixed sleeve 9 and fixedly connected by screws.

[0033] The length direction of the U-shaped connecting plate 10 is perpendicular to the axial direction of the fixed cylinder 9. The opening of the U-shaped connecting plate 10 faces the fixed cylinder 9 located in the same movable sleeve 8. The end of the short rod 3 away from the locking member is located inside the U-shaped connecting plate 10 and is rotatably connected to the U-shaped connecting plate 10. A locking block 11 is provided inside the U-shaped connecting plate 10. The length direction of the locking block 11 is parallel to the opening direction of the U-shaped connecting plate 10, and the longitudinal section of the locking block 11 gradually decreases from the opening to the bottom along the opening direction. In this embodiment, the locking block 11 is integrally formed with the U-shaped connecting plate 10. The end of the short rod 3 away from the connecting frame 5 is located inside the U-shaped connecting plate 10 and is rotatably connected to the U-shaped connecting plate 10 by a pin. The short rod 3 can be inserted into the U-shaped connecting plate 10 through the opening of the U-shaped connecting plate 10 along the locking block 11, and the locking block 11 can prevent the short rod 3 from coming out of the U-shaped connecting plate 10.

[0034] Reinforcing ribs are provided between the U-shaped connecting plate 10, the fixed cylinder 9, and the movable sleeve 8. In this embodiment, the U-shaped connecting plate 10, the fixed cylinder 9, the movable sleeve 8, and the reinforcing ribs are integrally formed. The reinforcing ribs improve the structural stability of the movable sleeve 8, the U-shaped connecting plate 10, and the fixed cylinder 9, thereby enhancing the stability of the crib.

[0035] Also includes a bed bag with a top opening (attached) Figure 1 (The dotted line indicates the location of the bed bag). The top of the bed bag is wrapped around the short frame rod 2 and the long frame rod assembly. The bottom of the bed bag has four connecting straps, which connect to the support rod 1 in a one-to-one correspondence. Specifically, the support rod 1 is inclined, tilting outwards from top to bottom via the movable connector. In this embodiment, the support rod 1 is inserted into the movable sleeve 8 and is detachably connected to the movable sleeve 8 by screws. Each peripheral wall of the support rod 1 has a vertically oriented slot 13.

[0036] The bed bag is square, with connecting straps at the bottom of its four edges. The side of each connecting strap away from the bed bag passes through a slotted hole 13, and a blocking block is located on the side where the connecting strap passes through the slotted hole 13. In this embodiment, the connecting strap is bonded to the blocking block. Each support rod 1 has a fixing block 12 at its bottom, with a through hole connecting its top and bottom surfaces. Each connecting strap has an adhesive component at its bottom, which passes through the through hole and connects to the fixing block 12. In this embodiment, the adhesive component is a Velcro fastener, with its free end passing through the through hole for bonding, thus connecting the Velcro fastener to the fixing block 12.

[0037] In the initial state, the short rods 3 of the same long frame assembly are close together, with the ends of the short rods 3 located at the notch, and the locking block 4 abutting against the bottom of the first groove of the locking part 6. A force is applied to the force plate 7, and the two locking members are pulled apart in opposite directions. The locking block 4 and the locking part 6 rotate relative to each other. When the two short rods 3 of the same long frame assembly are aligned, the applied force is stopped. Under the force of the elastic element, the locking block 4 moves into the second groove of the locking part 6. At this point, the support rod 1, the short frame rod 2, and the long frame assembly form a stable stroller frame.

[0038] This design improves the structural stability of the crib by incorporating support rod 1, short frame rod 2, and long frame rod components. Combined with the crib bag, it enhances safety during use. Furthermore, the use of locking mechanisms and movable connectors allows the crib to be folded and stored easily.
