Product introduction of plastic baby carriage wheels
Plastic baby car wheels are the "mobile cornerstone" of children's carts, scooters, balance bikes and other children's carts. They take safety as the core and take into account durability and flexibility, making every slide for children full of peace and fun.
Its safety performance is controlled from the source of the material. It is made of food-grade HDPE and modified PP composite injection molding, and does not contain harmful ingredients such as bisphenol A and phthalate. It has passed the national toy safety standard GB6675. The hardness of the material reaches Shaw D75, which not only ensures load-bearing stability (single-wheel static load-bearing ≥50kg), but also has moderate elasticity and can buffer road bumps. The surface has been specially treated and the friction coefficient is stable between 0.6-0.8, avoiding excessive smoothness and causing slippage. It will not increase the resistance due to excessive friction. It will save effort and effortlessness when pedaling by the child.
Structural design hides careful considerations of children's behavior. The wheel hub adopts a combination of "radial reinforcement ribs + central bearings". The 8 reinforcement ribs are evenly distributed at 360°, and the torsional strength is increased by 40%. Even if the child turns sharply or brakes suddenly, the wheel body will not be deformed. The bearing adopts a silent deep groove ball structure, and the noise is ≤45 decibels when rotating, so as to avoid harsh sounds that scare children and will not disturb family rest. The rim is wrapped with 1.5mm thick TPR soft rubber, which feels similar to rubber but is more wear-resistant. It can absorb vibration when in contact with the ground. When passing through thresholds and gravel roads, the bumpy feeling is reduced by 60%, protecting the child's spine and brain.
Detailed design highlights humanity. The wheel diameter is from 5cm to 12cm, and is suitable for children's strollers of different age groups: small diameter wheels (5-8cm) are suitable for 1-3 year old trolleys, flexible steering, which is convenient for parents to turn in narrow spaces; large diameter wheels (10-12cm) are suitable for 3-6 year old scooters and balance bikes, with large rolling inertia, making children smoother in sliding. The wheel axle uses an anti-rust galvanized steel core, which is closely connected to the wheel body, with a gap of ≤0.2mm to prevent loose and abnormal noise. Some styles have brake slots and can be matched with a child car brake system. The wheels can be locked quickly when the brake is pressed. The brake distance is 30% shorter than that of ordinary wheels, making it more reliable in emergencies.
Durability can withstand daily tossing. After 100,000 rolling tests (simulating the child to slide continuously for 20 kilometers), the wheel body has no cracks or obvious wear; after low temperature test of -20℃, it remains elastic and is not easy to brittle when used outdoors in winter; during the impact resistance test, it falls from a height of 1 meter to the cement floor, and the structure is intact. The wheel surface pattern adopts a "raindrop-shaped anti-slip chute" design, which increases the grip of the ground on rainy or wet ground by 25%, reducing the risk of side slippage.
From the community square to the park trail, from the indoor game area to the outdoor camping site, this plastic baby car wheel is suitable for all kinds of baby car scenes. Whether it is a stroller promoted by parents or a toy car controlled by children independently, it can become a reliable partner for children to explore the world with stable performance and considerate details, making every move safe and worry-free and full of laughter.
