Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, and in particular to an infant walking belt. Background Technology

[0002] A baby walking harness is an assistive tool designed to help infants and toddlers learn to walk. It usually consists of a wide strap and a fixing device, which is tied around the baby's chest or waist. Parents provide support and traction through the strap at the back to prevent the baby from falling.

[0003] Existing baby walking harnesses typically use a fixed pull cord mechanism, achieved through safety buckles or similar methods. For example, Chinese patent CN203987147U discloses a technical solution for assembling an infant walking harness, the structure of which includes a waist belt, two lugs on the waist belt, and a handle connected to the lugs via a strap. The waist belt includes a middle fabric and left and right waist fabrics connected to both sides of the middle fabric via zippers. The tops of the left and right waist fabrics are fixedly connected to the lugs with needle and thread. The bottom of the strap is movably connected to the lugs via a snap fastener. The top of the strap is connected to both sides of the handle via plastic buckles. The lugs are filled with sponge. The left and right waist fabrics also have a cushioning sponge layer at the location where the strap is located to protect the infant's underarms.

[0004] Because existing walking harnesses are not only not adjustable in length, but also cannot be used independently, they lose their value after the baby learns to walk, and their lifespan is very short. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an infant walking harness that is simple in structure, easy to use, has a one-way locking mechanism, and is highly safe. To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A baby walking harness includes:

[0007] Baby ties are used to wrap and secure an infant's body.

[0008] A pull cord is attached to the upper end of the strap and provides a lifting force to the strap.

[0009] The handle is hollow, and the pull rope is threaded through the handle. The handle and the pull rope are connected by a locking mechanism.

[0010] When the locking mechanism is in the locked state, pulling the lever can keep the length of the pull rope at a fixed length, so that the pull rope can be used to lift the strap to realize the use of the walking belt;

[0011] When the locking mechanism is in the unlocked state, the distance between the strap and the grip can be changed by pulling the cord.

[0012] Based on the above technical solution, the present invention may also adopt the following further technical solutions:

[0013] The locking mechanism includes a one-way locking mechanism located inside the grip and a button located on the grip. The lower part of the button is provided with a locking piece that extends into the grip, and the end of the locking piece abuts against the one-way locking mechanism.

[0014] The one-way locking mechanism includes a rotating part and a locking part. The upper part of the locking part has a locking cavity, and the end of the locking piece extends into the locking cavity and abuts against the locking part.

[0016] The rotating part includes a rotating shaft, a helical gear fixed on the rotating shaft, and a rope threader on both sides of the helical gear. The rope threader has a rope threading cavity, and the cavity wall of the rope threading cavity is provided with fixed teeth. The pull rope is threaded through the rope threading cavity of the rope threader and is tightly squeezed and fixed with the fixed teeth. When the pull rope is pulled, the pull rope drives the rope threader to rotate, and the rotation of the rope threader drives the helical gear and the rotating shaft to rotate.

[0017] The rope threader includes a first rope threader and a second rope threader. The first rope threader is integrally formed with a helical gear. The helical gear has a fixing groove. The second rope threader has an outwardly protruding fixing block. The fixing block is inserted into the fixing groove to fix the second rope threader and the helical gear.

[0018] The first rope threader, the second rope threader, and the helical gear all have through holes at their centers, and the rotating shaft is inserted through the through holes.

[0019] The handle has a rotating shaft seat inside, which has a shaft hole. The end of the rotating shaft extends out of the rope threader and is confined within the shaft hole of the rotating shaft seat.

[0020] When the button is near the outer end of the grip, the locking mechanism is in a locked state; when the button is near the center of the grip, the locking mechanism is in an unlocked state.

[0021] The strap includes a main body, a shoulder strap located on the upper part of the main body, and a waist belt located on the side of the main body. A protective pad is also provided on the front of the main body.

[0022] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0023] This invention, through its one-way locking mechanism, allows for quick adjustment of the pull cord length, adapting to the baby's height and making the baby walker suitable for infants of various heights. Furthermore, the one-way locking mechanism prevents the pull cord from lengthening during use, significantly improving safety and preventing falls caused by the walker suddenly becoming too long.
