Description

Technical Field

[0001] This utility model relates to the field of baby crib technology, and in particular to a baby crib foot extension and adjustment device. Background Technology

[0002] Chinese Patent Document No. CN207168269U, published on April 3, 2018, discloses a telescopic support structure for a children's bedside table. Located in the base of the bedside table, the structure includes a base tube and a telescopic tube inserted into the base tube from one end. A telescopic wheel is installed on the outer end of the telescopic tube, while the inner end is installed inside the base tube. A telescopic outer tube is installed inside the base tube, and a telescopic inner tube is fitted inside the outer telescopic tube. The other end of the telescopic inner tube is connected to the telescopic tube. A spring is fitted outside the telescopic inner tube, and the spring presses against the telescopic tube and the telescopic outer tube to form a reset mechanism for the telescopic wheel. This invention, through the design of a structure in which the telescopic tube, piston, spring, telescopic outer tube, and telescopic inner tube cooperate with each other, allows the telescopic wheel on one side of the wheel base to extend and retract. The telescopic tube of this outrigger structure is telescopically mounted on the base tube, allowing the telescopic wheels on one side of the wheel section to extend and retract. This ensures that the wheels are wide enough during normal use to prevent the crib from tipping over, while shortening the wheel distance when used with an adult bed to ensure a close fit. However, this outrigger structure lacks a locking mechanism, making the telescopic tube prone to loosening. Some outrigger structures on the market have a locking mechanism that is unlocked by pressing a button, but this button can be accidentally pressed by a child or a single accidental press can cause the telescopic tube to unlock.

[0003] Therefore, further improvements are necessary. Utility Model Content
