Description

Technical Field

[0001] This utility model relates to the technical field of baby cribs, and more particularly to a height-adjustable structure for baby cribs. Background Technology

[0002] In existing crib designs, the height of the crib board typically needs to be adjusted according to the baby's growth stage. When the baby is small, the board is set higher for easy daily care by parents; as the baby grows, the board is lowered to prevent falls when the baby rolls over or climbs. However, current height adjustment mechanisms often use screws or simple clips, which are cumbersome to operate, requiring parents to repeatedly disassemble and reassemble, increasing inconvenience. Furthermore, some structures are prone to clip wear and screw loosening over long-term use, leading to a decrease in the reliability of the crib board's fixation.

[0003] On the other hand, some products, in pursuit of quick adjustment, have designed simple pin-type positioning structures. However, due to the low precision of the fit between the positioning hole and the pin, the pin may loosen or even fall off when the baby moves frequently or the crib is impacted. More seriously, if only a single locking component bears the load and prevents slippage, wear or misoperation causing the lock to fail could lead to a sudden slippage of the crib, seriously affecting the safety of the baby crib.

[0004] In view of this, the inventor has specifically designed a height-adjustable structure for a crib, which leads to this invention. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this application is to provide a height-adjustable structure for a crib, which at least solves the safety problems of unstable positioning, unreliable load-bearing, and accidental unlocking during the height adjustment of the crib bed board.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a height-adjustable structure for a crib, including a column assembly, a mounting base, a support arm, and a locking assembly. The column assembly is vertically arranged and has a row of positioning holes distributed along its length on its outer wall. The mounting base is a box-shaped structure sleeved on the outside of the column assembly. The inner wall of the mounting base slides in conjunction with the guide portion of the column assembly, and the mounting base has an insertion slot. The rear end of the support arm has an insertion block segment that inserts into the insertion slot of the mounting base and abuts against its guide surface. The lower edge of the insertion block segment abuts against the mounting base to form a limiting stop. The front end of the support arm forms a support surface for supporting the crib frame.

[0009] In a further embodiment, the outer wall of the column assembly is recessed with a guide groove.

[0010] In a further embodiment, the inner wall of the insertion port is provided with an oblique reinforcing rib, which is used to improve the root bearing strength after the support arm is inserted.

[0011] In a further embodiment, guide planes are formed on both sides of the insert segment of the support arm, and the guide planes fit against the inner wall of the hook-and-mount socket. The insert segment is provided with a stepped positioning notch.

[0012] In a further embodiment, the upper edge of the support arm and the upper edge of the socket form a stop structure that abuts against each other.

[0013] In a further embodiment, the end face of the support arm away from the insertion block section is provided with a docking interface for connecting the crib tube.

[0014] In a further embodiment, the interface is provided with a second reinforcing rib.

[0015] In a further embodiment, the column assembly includes an inner tube and an outer tube, with the inner tube fitted inside the outer tube.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention has the following advantages: The positioning holes of the upright assembly and the sliding engagement with the mounting base enable multi-level height adjustment of the crib, avoiding the inconvenience and poor stability caused by traditional single screw or clip fixation. The support arm uses a plug segment inserted into the mounting base and fitting against the guide surface, with the upper and lower edges forming a stop, effectively bearing the weight of the crib and preventing swaying, making it more reliable in terms of load-bearing stability than existing structures. The diagonal reinforcing rib one inside the plug and the reinforcing rib two inside the interface improve the strength of the support arm root and connection parts, solving the defects of wear or deformation that easily occur during long-term use. At the same time, the upright assembly adopts an inner tube and outer tube sleeve method, which improves the overall strength and impact resistance, making the structure more flexible in height adjustment while further enhancing the safety and durability of the crib.

[0023] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] like Figure 1 As shown, this utility model provides a height-adjustable structure for a crib. Its core lies in the cooperative design of the upright assembly 1, the hanging seat 2 and the support arm 3, combined with a reasonable locking and bearing method, to achieve safe and stable height adjustment and support for the crib bed board.

[0025] like Figure 2 As shown, in a preferred embodiment, the support column assembly 1 is arranged vertically and fixed to the side panel or legs of the crib. The outer wall of the support column assembly 1 has a row of positioning holes 13 evenly distributed along its length, allowing the user to adjust to different heights as needed. To ensure smooth adjustment and anti-sway performance, the outer wall of the support column assembly 1 has a recessed longitudinal guide groove 14, serving as a guide for the sliding engagement of the mounting base 2. Furthermore, the support column assembly 1 can consist of an inner tube 11 and an outer tube 12, with the inner tube 11 fitted inside the outer tube 12, thereby enhancing the overall structural strength and impact resistance, and facilitating flexible installation on cribs of different sizes.

[0026] like Figure 2 and Figure 5As shown, the mounting bracket 2 is an integrally formed box-shaped structure, which is fitted onto the outside of the column assembly 1 and can slide up and down along the column. The inner wall of the mounting bracket 2 slides into the guide groove 14 of the column, ensuring the straightness and stability of its movement. A socket 21 is provided on one side of the mounting bracket 2 for inserting the support arm 3. To improve the insertion strength, the inner wall of the socket 21 is provided with diagonal reinforcing ribs 22, so that the support arm 3 can obtain additional support at the root after insertion, avoiding deformation caused by long-term stress.

[0027] like Figures 2 to 4 As shown, the support arm 3 has a beam structure with a plug section 31 at its rear end. The plug section 31 is inserted into the socket 21 of the mounting base 2 and fits against its guide surface. Guide planes 34 are formed on both sides of the plug section 31, which fit tightly against the inner wall of the mounting base 2, preventing the support arm 3 from shaking after insertion. A stepped positioning notch 35 is provided on the plug section 31. After the support arm 3 is inserted, the notch can cooperate with the positioning hole row 13 or the locking tongue of the locking assembly to reliably lock the position. The lower edge of the support arm 3 abuts against the lower edge of the mounting base 2 to form a limiting stop 32, which bears the main vertical load of the bed board, preventing the locking tongue from directly bearing pressure and further improving the reliability of the structure.

[0028] The front end of the support arm 3 forms a support surface 33 for connecting to the crib frame. Specifically, the support surface 33 can be pre-set with screw holes or dovetail grooves, allowing the crib frame to be securely installed on the support arm 3 via screw fixing or quick-release plug-in connection, ensuring both a strong connection and easy assembly and disassembly. To further enhance structural strength, a mating interface 36 is provided on the end face of the support arm 3 away from the insertion block section 31. This interface 36 can be used for docking with other crib fittings, and it is internally reinforced with reinforcing ribs 37 to improve overall load-bearing capacity and torsional resistance.

[0029] In practical applications, when adjusting the height of the crib, the user can first release the safety fastener, then slide the hook-and-mount 2 along the upright along the column to select a suitable positioning hole position. When the positioning notch 35 of the insert segment 31 aligns with the hole on the upright, the locking component in the hook-and-mount 2 will automatically spring in and engage, completing the initial locking. Subsequently, the stop of the support arm 3 abuts against the stop of the hook-and-mount 2, bearing the downward pressure, and further preventing the support arm 3 from falling off through secondary fixing. The entire operation process is simple and quick, while ensuring the reliability of the support arm 3 at different height positions.

[0030] Compared with existing adjustment structures that rely solely on a single screw or pin for fixation, the advantages of this invention are as follows: Firstly, the cooperation between the guide groove 14 and the guide surface ensures the stability of the support arm 3 during insertion and sliding. Secondly, the vertical load is distributed through the stop structure, avoiding direct stress on the locking component and improving its service life. Simultaneously, the addition of reinforcing ribs 22 and mating interfaces 36 at key locations on the support arm 3 and the mounting base 2 significantly enhances the overall strength. The inner and outer tubes 12 of the upright further enhance the overall stability, enabling it to withstand the impact and shaking caused by the baby's movements within the crib, significantly improving the safety and durability of the crib.

[0031] Therefore, this specific implementation not only achieves multi-level height adjustment of the bed board, but also achieves a good balance between ease of operation and safety and reliability, providing an efficient, stable and safe height adjustment solution for the actual use of cribs.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
