Description

Technical Field

[0001] This utility model relates to the field of anti-rollover baby crib technology, specifically an anti-rollover baby crib leg support structure. Background Technology

[0002] Baby cribs are special bedding designed for infants and toddlers. They are classified by material into solid wood, bamboo, rattan, and composite materials, and by usage into types such as rocking cribs and hanging cribs.

[0003] In existing technologies, traditional crib support structures have relatively limited functionality, often requiring a trade-off between mobility and rocking capabilities, making it difficult to achieve both simultaneously. Cribs with rocking functions pose a risk of tipping over due to a shift in the center of gravity when the baby is active or learning to stand.

[0004] Therefore, there is an urgent need to design a crib leg support structure that can solve the above problems and prevent tipping over. Summary of the Invention

[0005] The purpose of this utility model is to provide a crib leg support structure to prevent tipping over. To achieve the above purpose, this utility model provides the following technical solution: A crib leg support structure for preventing tipping out includes a crib body. The top of the crib body is symmetrically provided with connecting rods. One end of each connecting rod is fixedly connected to a rotating cylinder. The rotating cylinder is connected to a bracket via a bearing seat. The bottom ends of the two brackets are provided with support plates. The bottom surface of each support plate is provided with spring dampers at the four corners. Each spring damper is fixedly connected to a self-locking caster wheel. A limiting component is provided between the crib body and the support plate. The two sides of the crib body are symmetrically provided with reinforcing components.

[0006] Furthermore, the limiting component includes hinge seats that are fixedly connected to the bottom surface of the bed and the surface of the support plate respectively, and a telescopic belt is provided between the two hinge seats; The above technical solution prevents excessive swaying and tipping. The connection between the movable bed and the fixed support plate sets the maximum safe angle for bed swaying. When the swaying amplitude is too large, the telescopic belt will be straightened to rigidly prevent the bed from tilting further and prevent its center of gravity from shifting too much, causing the entire bed to tip over.

[0007] Furthermore, the reinforcement component includes symmetrically arranged slots with upward openings on the support plate, a rotating shaft inside the slot, a connecting sleeve outside the rotating shaft, the connecting sleeve connecting the reinforcement plate, a positioning plate on the connecting sleeve, and the positioning plate being fixed to the support plate by bolts. Through the above technical solution, the positioning plate and bolts are used to firmly lock the unfolded reinforcing plate in the correct position, ensuring that it will not be accidentally retracted during use, and can be stored together with the U-shaped reinforcing plate on the support plate.

[0008] Furthermore, the reinforcement component also includes symmetrically arranged grooves on the reinforcement plate, and a U-shaped rod is provided inside the groove. The U-shaped rod is fixed to the groove by bolts. The above technical solution directly and rigidly limits the shaking of the bed. Pulling out the U-shaped rod to its limit can directly limit the position of the bed and prevent it from shaking. Retracting the U-shaped rod does not affect the shaking.

[0009] Furthermore, the reinforcement component also includes a groove provided at the top of the reinforcement plate, with positioning holes symmetrically provided on the inner sidewall of the groove, a baffle provided at the top of the positioning hole, an anti-tipping plate provided at the bottom of the baffle, a recess provided at one end of the anti-tipping plate, and a counterweight provided at the top of the recess. The above technical solution uses counterweights in conjunction with angled anti-tipping plates to lower the center of gravity, increase the contact area with the ground, and prevent the bed from shaking and tipping over.

[0010] Furthermore, the top of the anti-rollover plate is symmetrically provided with fixing blocks, one side of the fixing blocks is provided with a spring, one end of the spring is fixedly connected to an L-shaped positioning rod, the top of the anti-rollover plate is provided with a sliding groove for sliding connection with the L-shaped positioning rod, and the end of the L-shaped positioning rod away from the spring is provided with a pull rod, the pull rod passes through the anti-rollover plate, and the anti-rollover plate is provided with an avoidance groove, the pull rod moves along the avoidance groove; The above technical solution enables quick disassembly and assembly of the anti-tipping plate, and allows it to be stored away when not in use for extended periods.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of an anti-tipping crib leg support structure, achieves the following effects: 1. The suspension rocking mechanism, composed of spring dampers and rotating cylinders, provides a smooth and comfortable rocking function. The limiting component acts as the first line of safety, effectively preventing excessive rocking. When the rocking amplitude is too large, the telescopic belt is straightened, rigidly preventing further tilting of the crib and preventing excessive shift of the center of gravity that could cause the entire crib to tip over; 2. The reinforcement components enhance the stability of the crib through various designs. The U-shaped rod directly and rigidly limits the crib's swaying, and when pulled to its limit, it completely limits the crib's position, preventing shaking; the anti-tipping plate, combined with a counterweight, lowers the center of gravity and increases the contact area with the ground, further preventing the crib from swaying and tipping over, providing a safer environment for the baby; 3. When the crib is not in use, all components can be disassembled with bolts for easy storage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0016] Please see Figure 1-6 This embodiment provides an anti-tipping crib leg support structure, including a crib body 1. Symmetrically arranged connecting rods 101 are provided at the top of the crib body 1. One end of each connecting rod 101 is fixedly connected to a rotating cylinder 102. The rotating cylinder 102 is connected to a bracket 103 via a bearing seat. Support plates 104 are provided at the bottom of the two brackets 103. Spring dampers 105 are provided at the four corners of the bottom surface of the support plates 104. Self-locking casters 106 are fixedly connected to the spring dampers 105. A limiting component 2 is provided between the crib body 1 and the support plates 104. Reinforcing components 3 are symmetrically arranged on both sides of the crib body 1. When the reinforcing component 3 is retracted, the reinforcing plate 302 is erected and fixed to the support plate 104, the U-shaped rod 305 is retracted, and the anti-tipping plate 307 is retracted. The crib can move freely using the self-locking casters 106. After being fixed, the vibrations from the baby's movements or shaking are transmitted to the spring damper 105 through the connecting rod 101 and the rotating cylinder 102 to absorb and buffer the vibrations. The limiting component 2 prevents excessive swaying. For a more stable environment, such as when the baby is learning to stand, loosen the bolts between the U-shaped rod 305 and the reinforcing plate 302, raise the U-shaped rod 305 to its highest position and limit it, so that the crib 1 cannot shake. Pull the pull rod 312 to insert the L-shaped positioning rod 311 into the positioning hole, assemble the anti-tipping plate 307 and the reinforcing plate 302 to increase the contact area with the ground, and place the counterweight 308 to increase the weight. When not in use, the components can be disassembled with bolts for storage.

[0017] like Figure 1 and Figure 2 As shown, the limiting component 2 includes hinge seats 201 that are fixedly connected to the bottom surface of the bed body 1 and the surface of the support plate 104 respectively, and a telescopic belt 202 is provided between the two hinge seats 201. When the reinforcing component 3 is fully retracted, the reinforcing plate 302 is fixed to the support plate 104 by bolts. At this time, the reinforcing plate 302 is erected, the U-shaped rod 305 is retracted, and the anti-tipping plate 307 is retracted. The crib can then move freely via the self-locking casters 106. Once fixed, any movement or rocking of the baby inside the crib will be transmitted to the spring damper 105 through the connecting rod 101 and the rotating drum 102, which will absorb and buffer the vibration, providing a comfortable rocking motion. At this time, the limiting component 2 acts as a safety rope to prevent excessive rocking.

[0018] like Figure 1 and Figure 3 and Figure 4 and Figure 5 and Figure 6As shown, the reinforcement component 3 includes symmetrically arranged upward-facing slots on the support plate 104. A rotating shaft is located inside the slot, and a connecting sleeve 301 is located outside the rotating shaft. The connecting sleeve 301 connects to the reinforcement plate 302. A positioning plate 303 is provided on the connecting sleeve 301, and the positioning plate 303 is fixed to the support plate 104 by bolts. The reinforcement component 3 also includes symmetrically arranged sliding grooves 304 on the reinforcement plate 302. A U-shaped rod 305 is located inside the sliding groove 304, and the U-shaped rod 305 is fixed to the sliding groove 304 by bolts. The reinforcement component 3 also includes a groove at the top of the reinforcement plate 302. Positioning holes are symmetrically provided on the inner sidewall of the groove. A baffle 306 is provided at the top, and an anti-tipping plate 307 is provided at the bottom of the baffle 306. One end of the anti-tipping plate 307 has a recess, and a counterweight 308 is provided at the top of the recess. A fixing block 309 is symmetrically provided at the top of the anti-tipping plate 307. A spring 310 is provided on one side of the fixing block 309. One end of the spring 310 is fixedly connected to an L-shaped positioning rod 311. The top of the anti-tipping plate 307 has a sliding groove for sliding connection with the L-shaped positioning rod 311. A pull rod 312 is provided at the end of the L-shaped positioning rod 311 away from the spring 310. The pull rod 312 passes through the anti-tipping plate 307, and an avoidance groove is provided on the anti-tipping plate 307. The pull rod 312 moves along the avoidance groove. When a more stable environment is needed, such as for a baby learning station, the bolts between the U-shaped rod and the reinforcing plate 302 need to be loosened, and the U-shaped rod 305 needs to be raised to its highest height. Then, the bolts are used to limit the position, and the U-shaped rod 305 completely limits the position of the bed 1, preventing the bed 1 from shaking. Then, the pull rod 312 is pulled, and the L-shaped positioning rod 311 compresses the spring 310 along the clearance groove and sliding groove. Then, one end of the L-shaped positioning rod 311 is aligned with the positioning hole, and the pull rod 312 is released. At this time, the L-shaped positioning rod 311 is inserted into the positioning hole, and the anti-tipping plate 307 and the reinforcing plate 302 are assembled, increasing the contact area with the ground. The counterweight 308 is placed on the anti-tipping plate 307 to increase the weight.

[0019] The working process of this utility model is as follows: When using this anti-tipping crib leg support structure, firstly, when the reinforcing component 3 is fully retracted, the reinforcing plate 302 is fixed to the support plate 104 by bolts. At this time, the reinforcing plate 302 is erected, the U-shaped rod 305 is retracted, and the anti-tipping plate 307 is retracted. The crib can then move freely via the self-locking casters 106. After being fixed, the baby's movements or shaking inside the crib will be transmitted to the spring damper 105 through the connecting rod 101 and the rotating cylinder 102, which absorbs and buffers the vibration, providing a comfortable rocking motion. At this time, the limiting component 2 acts as a safety rope to prevent excessive rocking amplitude. When a more stable environment is needed, such as for a baby learning station, the bolts between the U-shaped rod 305 and the reinforcing plate 302 need to be loosened, and the U-shaped rod 305 raised to its highest height. Then, the bolts are used to limit the position, completely fixing the bed frame 1 so it cannot shake. Next, the pull rod 312 is pulled, causing the L-shaped positioning rod 311 to compress the spring 310 along the clearance groove and sliding groove. Then, one end of the L-shaped positioning rod 311 is aligned with the positioning hole, and the pull rod 312 is released. The L-shaped positioning rod 311 is now inserted into the positioning hole, completing the assembly between the anti-tipping plate 307 and the reinforcing plate 302, increasing the contact area with the ground. The counterweight 308 is then placed on the anti-tipping plate 307 to increase the weight. When not in use, the components can be disassembled using bolts for easy storage.
