Technical Field

[0001] This utility model relates to the field of baby walker technology, and in particular to a portable baby walker. Background Technology

[0002] Baby walkers help babies stand and walk, providing support to reduce the risk of falls while also exercising leg muscles and balance. Their wraparound design encourages independent exploration, enhances spatial awareness and self-confidence, and lays the foundation for independent walking, making them an effective tool for the gross motor development of infants and toddlers.

[0003] 1. Existing baby walkers are bulky after installation, making them inconvenient to fold when needed, resulting in a large space requirement for carrying and storage.

[0004] 2. The height of the baby walking handrail is fixed and cannot be adapted to babies of different heights. Different sizes of products need to be purchased separately. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as large overall structure, inconvenient folding when needed for storage, large space occupation for carrying and storage, and fixed armrest height, which cannot adapt to infants of different heights. Therefore, this invention proposes a portable baby walker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable baby walker includes:

[0008] Two second support frames and two first support frames are provided. The second support frames are fixedly connected to connectors by bolts. The first support frames are rotatably connected to the connectors. The second support frames are rotatably connected to locking rods. The locking rods are engaged with the locking shafts of the first support frames through locking grooves.

[0009] A crossbar is provided between the two second support frames. Connecting frames are fixed at both ends of the crossbar. Handrails are fixedly connected between the two connecting frames. A moving groove is provided inside the connecting frame. An abutment block is slidably connected to the moving groove. The abutment block extends outside the moving groove. A spring is provided inside the moving groove. The two ends of the spring are respectively connected to the inner wall of the moving groove and the abutment block.

[0010] In one possible design, each of the two second support frames has a through groove at one end, a through shaft is fixedly connected to the end of the abutment block, the through shaft passes through the through groove, a face gear is provided at the end of the abutment block, a face tooth groove is provided on the inner wall of one end of the through groove, and the face gear engages with the face tooth groove.

[0011] In one possible design, the top of the connector is fixedly connected to a baffle, the bottom of the connector abuts against the top of the end of the first support frame, the front wheel is rotatably connected between the two second support frames, and the rear wheel is rotatably connected to the side of the two first support frames that are far apart from each other.

[0012] In one possible design, manually moving the locking lever disengages the locking slot from the locking shaft, folds the first support frame to one side of the second support frame, pushes the abutment block to disengage the face gear from the face tooth groove, and flips the connecting frame to store the handrail between the two second support frames.

[0013] In one possible design, the spring reset pushes the abutment block to move, and the face gear re-engages with the face tooth groove, thereby fixing the handrail after height adjustment.

[0014] In one possible design, the locking rod is connected to the second support frame via a rotating shaft, and the locking shaft is fixed to the side of the first support frame by welding.

[0015] In this application, the front wheel is positioned between two second support frames, and rear wheels are installed on the opposite sides of the two first support frames. By turning the locking lever, the locking groove at one end of the lever disengages from the locking shaft on one side of the second support frame. Flipping the first support frame allows the locking lever to rotate, engaging the locking groove at one end with the locking shaft on one side of the first support frame, thus providing support between the first and second support frames. When used by an infant, the infant holds the handle, and the front wheel and two rear wheels move on the ground with the support of the second and first support frames. The height of the handle can be adjusted by pushing the two connecting frames. The lower abutment block compresses the spring. As the abutment block moves, it releases the engagement between the face gear and the face tooth groove. At the same time, the through shaft moves laterally within the through groove. At this point, the connecting frame can be rotated to flip the angle on one side of the second support frame, thereby adjusting the height of the other end of the connecting frame. Releasing the push on the abutment block resets the spring, allowing the face gear at one end of the abutment block to engage and fix with the face tooth groove, thus adjusting the height of the handrail. When storing, by releasing the engagement between the face gear and the face tooth groove, the handrail can be stored between the two second support frames. The two first support frames can be folded to the sides of the two second support frames.

[0016] Beneficial effects: In this utility model, the portable baby walking frame can be unfolded and supported by the first support frame when in use, and is supported by the locking rod. When stored, the first support frame can be folded to one side of the second support frame, which significantly reduces the volume and makes it easy to carry and store.

[0017] In this utility model, a portable baby walker is provided. Pushing the abutment block squeezes the spring to release the engagement between the face gear and the face tooth groove, adjusting the angle of the connecting frame and driving the height adjustment of the armrest. After releasing, the spring returns to its original position and is fixed, realizing precise adjustment of the armrest height to meet the usage needs of babies of different heights.

[0018] In this invention, the pushing abutment block compresses the spring to release the engagement between the face gear and the face tooth groove, adjusts the angle of the connecting frame and drives the armrest to rise and fall. After being released, the spring returns to its original position and is fixed, thus achieving precise adjustment of the armrest height to meet the usage needs of infants of different heights.
