[0026] Bed frame 12: Three guard panels (left guard panel 121, right guard panel 122, and rear guard panel 123) are arranged around the three end faces of the base plate 11 to form a U-shaped closed space.

[0027] Left / right guard plate 122: symmetrically arranged, and each of the left / right guard plates 122 has several mounting grooves 1221 evenly distributed.

[0028] Rear guard plate 123: fixed to one side of the base plate 11, and both ends of the rear guard plate 123 are connected to the left / right guard plates 122.

[0029] The receiving groove 13 includes a bottom groove 131 on the bottom plate 11 and a side groove 132 on the left / right guard plate 122, which are connected.

[0030] Solid foundation: The U-shaped three-sided enclosure provides initial safety space to prevent babies from falling.

[0031] The specific structure of extended component 2 includes:

[0032] Substrate 21: It is movably installed in the bottom groove 131 and has a locking groove 32 at one end near the limiting mechanism 3.

[0033] Limiting plate 23: symmetrically fixed at both ends of the base plate 21, and movably embedded in the side groove 132 to limit lateral displacement.

[0034] End plate 22: connects the top of the two limiting plates 23 to form an expanded enclosure surface; and the outward end of the end plate 22 is provided with an expansion groove 221.

[0035] The expansion slot 221 has a built-in removable cutting plate 222, which is adapted to the mounting slot 1221 on the left / right guard plate 122.

[0036] Modular expansion: The play bed area can be quickly increased by pulling out the base plate 21 to meet the needs of activity or sleep.

[0037] Flexible partitioning: After the cutting plate 222 is inserted into the mounting slot 1221, the space can be divided (such as a game area / sleep area), enhancing its versatility.

[0038] The specific limiting mechanism 3 includes:

[0039] Locking block 31: It is movably inserted into the insertion slot 111 on the base plate 11 and can be operated manually.

[0040] Locking groove 32: Located on the base plate 21 of the extension component 2, it engages with the locking block 31.

[0043] Quick operation: One-click lock / unlock mechanism, allowing parents to make adjustments with one hand.

[0044] The working principle of this utility model:

[0045] 1. Initial state:

[0046] Option A: The playbed body 1 consists of a base plate 11 and three bed frames 12 (left / right guardrails 122 + rear guardrail 123) forming a U-shaped enclosed space. The extension component 2 is completely separate from the playbed body 1 and can be placed independently or used as a standalone device.

[0047] Option B (built-in insertion): The extension component 2 is inserted into the receiving slot 13 of the game bed body 1 in advance (at this time, the locking block 31 is inserted into the locking slot 32 and into the locking slot 32 on the base plate 21 to complete the mechanical locking).

[0048] 2. Spatial Expansion

[0049] The user manually operates the locking mechanism (e.g., pulling it outwards) to disengage it from the locking groove 32. The extension component 2 is then released and can be pulled outwards along the receiving groove 13 (bottom groove 131 + side groove 132). Then, the end plate 22 is pulled horizontally outwards, causing the base plate 21 to slide out of the bottom groove 131, and the limiting plate 23 moves along the side groove 132. When the extension component 2 reaches a certain travel distance, it pushes the locking block 31 to abut against the locking groove 32 again (manual locking) to prevent retraction. The end plate 22 of the extension component 2 forms a closed fourth enclosure with the original bed frame 12, increasing the play bed area.

[0050] 3. Reclaim expansion component 2

[0051] Solution A: Unlock the locking block 31 and push the end plate 22 inward. Push the extension component 2 completely back into the receiving slot 13, then relock it with the locking block 31 to restore the initial state.

[0052] Option B: Insert the cutting plate 222 into the mounting slot 1221 to divide the unfolded play bed into a play area and a sleep area.

[0053] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
