Description

Technical Field

[0001] This utility model relates to the field of children's beds, and in particular to a multifunctional children's anti-fall bed. Background Technology

[0002] An existing patent (publication number: CN202515125U) discloses a children's bed, including a bed frame and a bed board. The bed frame includes four uprights, a headboard railing, a first side railing, and a second side railing. Each upright has a mosquito net pole fixing seat fixed at its upper end. The mosquito net pole fixing seat is a rotating body with a pole fixing hole at its upper end. However, the railing height in this device is fixed and cannot be adjusted according to the child's growth. This poses a risk of accidental falls when the child rolls over, as the child grows taller and becomes more active. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a multifunctional children's anti-fall bed that features storage, fall prevention, and other functions. The height of the fall prevention barrier can be adjusted according to the child's growth and activity level, adapting to mattresses of different thicknesses to meet the protection needs of children at different stages of growth. It is also flexible in structure and easy to assemble and disassemble.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A multifunctional child fall-prevention bed includes a bed frame, a rack, a rotating sleeve, a locking sleeve, a movable shell, a retaining plate, a protective rod, and a fall-prevention barrier. The lower part of the bed frame is connected to a drawer, and the upper part is connected to a headboard. The bed frame has side grooves that adapt to the movable shell and connect to it. The movable shell has rack grooves that adapt to a rack and connect to it. The rack and connect to the bed frame. The rack has retaining slots on both sides that adapt to the retaining plate and connect to it. The retaining plate connects to a spring strip, which connects to the movable shell. The movable shell fits snugly against the retaining plate. The retaining plate has a lever groove. The movable shell has sliding holes on both sides that adapt to a lever. The lever passes through the sliding hole, and the lower end of the lever is threaded into the lever groove.

[0006] The movable shell of this utility model is connected to the rotating sleeve by a shaft. The shaft passes through the movable shell and the rotating sleeve in sequence. The rotating sleeve has a gear on its outside. The gear meshes with a rack and is connected to the rack. The rotating sleeve passes through a locking sleeve. The locking sleeve has a locking block on its inner side. The rotating sleeve has multiple locking grooves. The locking block is adapted to the locking grooves and is connected to the locking grooves.

[0007] The gear is fitted inside the lock sleeve of this utility model, and the movable shell is fitted outside the lock sleeve. The movable shell is connected to the outside of the bearing, and a threaded rod is connected inside the bearing. The inner end of the threaded rod is connected to the lock sleeve by a thread, and the outer end of the threaded rod has a knob that fits into the movable shell. Beneficial effects

[0008] This utility model features drawers at the bottom of the bed to increase storage space, making it convenient to categorize and store children's toys, seasonal clothing, etc., thereby improving the utilization of the space under the bed and enhancing its functionality. Anti-fall barriers are added to the sides of the bed to provide surrounding protection and prevent children from falling off the bed, thus improving children's safety.

[0009] This utility model's movable shell uses two side plates embedded in slots to engage with the rack, preventing them from disengaging and maintaining linear displacement, thus improving the stability of the movable shell during adjustment. The meshing connection between the gears and rack allows for adjustable positioning height of the movable shell, adapting to changes in a child's height and activity level. This allows for corresponding adjustments to the height of the fall protection barrier, meeting the protection needs of children at different growth stages, extending its service life, and making it compatible with mattresses of different thicknesses. The structure is flexible and highly practical. Furthermore, the support rod and protective rod are fixed by an insertion connection, and the protective rod is threaded to the movable shell, making assembly and disassembly convenient.

[0010] This utility model's locking sleeve uses a positioning connection between a threaded rod and a threaded thread, allowing the locking sleeve to be driven and positioned by rotating a knob. When the locking sleeve moves to the point where the locking block is embedded in the locking groove, it increases the positioning fulcrum for the rotating sleeve. At this time, the gear is braked and locked, preventing rotation, thus ensuring the rack provides stable support for the movable shell. When the locking sleeve moves to the point where the locking block is completely disengaged from the locking groove, the positioning fulcrum for the rotating sleeve disappears. At this point, the support height of the anti-fall barrier can be adjusted according to actual usage needs by moving the movable shell. The operation is convenient, and the reasonable protection height ensures both the anti-fall effect and avoids a feeling of oppression, resulting in a reasonable structure.

[0011] This utility model has functions such as storage and fall prevention. The height of the fall prevention barrier can be adjusted according to the child's height and activity level as the child grows. It can be adapted to mattresses of different thicknesses to meet the protection needs of children at different growth stages. The structure is flexible and easy to disassemble and adjust.
