Description

Technical Field

[0001] This utility model relates to the technical field of guardrail adjustment structures, specifically to a height adjustment structure for a children's bed guardrail. Background Technology

[0002] As a core component for ensuring the safety of young children, the height adjustment function of children's bed rails directly affects their ease of use and safety. Currently, the height adjustment structures of children's bed rails on the market generally have the following problems: (1) Poor ease of operation: Most adjustment structures require the cooperation of both hands to complete multiple steps. Parents often find it difficult to operate with one hand when supervising young children, especially when the child is crying and needs to be soothed at the same time, resulting in extremely low operation efficiency. (2) Safety hazards: Some structures adopt a single-button unlocking design, which can easily lead to accidental unlocking of the railing due to accidental touch or collision by the child, posing a risk of the railing slipping off; other structures have insufficient positioning accuracy, and the railing is prone to loosening and shaking after adjustment, failing to stably support the child's leaning. (3) Contradiction between adjustment range and stability: In order to achieve multi-level adjustment, some products have simplified the positioning mechanism, resulting in a worse structural stability with more adjustment levels, and failing to meet the different needs of children of different ages for railing height.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a height-adjustable structure for children's bed rails that is easy to operate and highly stable, so as to solve the pain points of parents and improve the safety of children. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a height-adjustable structure for children's bed rails, addressing the above-mentioned shortcomings of the existing technology.

[0024] The working principle of this utility model: Pressing the first button 3 causes it to move inward along the first mounting opening 105, simultaneously moving the L-shaped limiting plate 301. The end of the L-shaped limiting plate 301 away from the first button 3 moves out of the limiting groove 102 on the other side of the slide groove 101, releasing the lateral lock on the slider 2. At this time, the spring 5 of the first button 3 is compressed. While keeping the first button 3 pressed, simultaneously pressing the second button 4 causes it to move inward along the second mounting opening 106, simultaneously moving the top plate 401. The inclined surface of the top plate 401 slides along the inclined groove 203 of the slider 2, converting the vertical pressure into a horizontal thrust, pushing the slider 2 to move away from the first positioning hole 103 along the slide groove 101. The positioning post 202 of the slider 2 moves out of the round hole of the adjusting rod 6 and the first positioning hole 103, releasing the positioning of the adjusting rod 6. At this time, the spring 5 of the second button 4 and the spring 5 of the slider 2 are both compressed. Press the third button 8, and the latch will move out of the second rod sleeve 701 and the corresponding second positioning hole on the adjusting rod 6. Keep all three buttons pressed, and pull the adjusting rod 6 upward. The adjusting rod 6 will slide upward until the target height is reached. At this time, the circular hole on the adjusting rod 6 corresponding to the height is coaxially aligned with the first positioning hole 103. Then, release the second button 4 and the first button 3 in sequence to complete the height adjustment.
