Abstract: The present disclosure discloses a wheel assembly structure and a child activity center. The wheel assembly structure includes a connection base and a wheel assembly that is deployable. The wheel assembly is pivotally connected to the connection base. The wheel assembly has a deployment state and a storage state. An adjustment mechanism is provided between the connection base and the wheel assembly. The adjustment mechanism is configured to switch the wheel assembly into the storage state from the deployment state. When the wheel assembly is in the deployment state, the wheel assembly is deployed to a first position to move the connection base. When the wheel assembly is in the storage state, the wheel assembly is stored to a second position to stably place the connection base. The wheel assembly structure has a simple overall structure, which facilitates production and lowers production costs.

Abstract: Provided is a wheel assembly device. The wheel assembly device includes a connection base, a wheel assembly that is deployable, and a positioning assembly configured to position the wheel assembly. The wheel assembly is movably connected to the connection base and switchable between a deployed position and a storage position. The connection base has a positioning space. The wheel assembly is configured to rotate to an interior of the positioning space when the wheel assembly is at the deployed position, and rotate to an exterior of the positioning space when the wheel assembly is at the storage position. The positioning assembly includes a first positioning member configured to cooperate with the positioning space to position the wheel assembly at the deployed position and a second positioning member configured to cooperate with the first positioning member to position the wheel assembly at the storage position.

Abstract: The present disclosure discloses an activity center structure for a child. The structure includes an activity center frame, a support bottom frame, a support leg, and an elastic surface having elasticity. The activity center frame is located above the support bottom frame, and provided with a seat pocket for placing the child at a middle part of the activity center frame. The support leg is connected between the activity center frame and the support bottom frame. The support bottom frame has a mounting position where the support bottom frame is hollow. The mounting position at least corresponds to a position where the seat pocket is located. The elastic surface is mounted at the mounting position to allow the child placed in the seat pocket to step on the elastic surface. In this way, the activity center structure has better safety performance.

Abstract: A cart handle and a baby cart in which cart handle includes a fixed member; a handle body rotatable relative to the fixed member; an engagement part having a first portion that non-rotatably engages the handle body and slidably engages the handle body, and having a second portion that non-rotatably engages the fixed member; and an operation part that is actuated to alternately displace the engagement part to an unlocked position, wherein the second portion is not in engagement with the fixed member, thereby permitting rotation of the handle body relative to the fixed member, and displace the engagement part to a locked position, wherein the second portion engages the fixed member, thereby preventing rotation of the handle body relative to the fixed member.
