StrollLock Tri-Secure Buckle

Designed exclusively for the baby stroller industry, our premium plastic side release safety buckle stands as a pivotal safety component engineered to redefine security and convenience for infant mobility products. Meticulously crafted from food-grade medical PP (Polypropylene) and high-strength POM (Polyoxymethylene) composite materials, this buckle undergoes a 12-step precision injection molding and ultrasonic welding process, eliminating sharp edges and ensuring 100% non-toxicity, BPA-free, and phthalate-free composition-fully compliant with the strictest global baby product safety standards including EU EN 1888:2018, US ASTM F2151-19, and CPSIA regulations. What sets it apart is the integrated anti-pry lock core technology; unlike ordinary buckles, its internal gear-locking mechanism resists forced opening by curious infants, while the tactile feedback design lets parents confirm a secure lock with a distinct "click" sound, erasing any doubts about safety.

We prioritize eco-friendliness: the buckle is made from 30% recycled PP material (without compromising strength) and is fully recyclable at the end of its life. For brand partners, we offer OEM/ODM customization-including custom Pantone color matching (over 50 baby-safe hues), laser-engraved brand logos, and even personalized button textures (e.g., animal-shaped grips for playful appeal). Our rapid prototyping service can deliver custom buckle samples in as little as 7 days, catering to the unique design needs of premium baby stroller brands worldwide.
 

Product Specification

Product Application

Infant-Centric Safety Engineering
The buckle features a rounded, skin-friendly finish with a 0.1mm smooth edge tolerance (polished via 3-stage buffing), preventing any abrasion or irritation to babies' delicate skin-even during active movements in the stroller. Its auto-locking system engages within 0.2 seconds of buckling, with a lateral pull resistance of up to 300N (30kg), far exceeding industry average load-bearing capacity

Superior Safety: Equipped with auto-locking structure, it can lock instantly after buckling, effectively preventing accidental release caused by babies' pulling, with strong load-bearing capacity to keep babies stable in the stroller. The rounded edge design with smooth polishing avoids scratches on babies' skin, ensuring gentle touch. Extreme Environmental Durability
Crafted from weather-resistant polymer blends, the buckle performs flawlessly in temperatures ranging from -40℃ to 90℃-resisting cracking in cold winter climates and deformation in hot summer car interiors. It is also water-resistant (IPX4 rating) and sweat-proof, with a hydrophobic surface that repels liquid and prevents mold growth, maintaining structural integrity even after repeated exposure to spills, rain, or baby's saliva. The matte anti-fingerprint coating keeps the buckle looking new, resisting scratches from stroller storage and daily use.

Ergonomic Parental Operation
Built with a ergonomic double-press release button (15° inclined design), the buckle allows parents to open it with one hand-even while holding the baby or carrying bags-requiring only 8N of force to press (30% less than standard buckles). The non-slip rubberized texture on the buttons enhances grip, making operation effortless even with wet or gloved hands. The male-female buckle interface is precision-machined to a 0.02mm tolerance, ensuring a snug fit that won't loosen during stroller movement, striking the perfect balance between easy adult operation and childproof security.

Universal Adaptability for All Stroller Types
Available in custom-calibrated sizes (16mm/20mm/25mm/32mm) to fit webbing widths of 3-point, 5-point, and even 7-point harness systems-the most comprehensive size range in the market. It is compatible with every major stroller category: from ultra-lightweight travel strollers (under 5kg) to high-view prams with elevated seating, twin strollers with dual harnesses, jogging strollers with shock-absorbing frames, and luxury lie-flat bassinet strollers. The buckle also supports both sew-on loop and slide-on webbing installation, with pre-molded stitch guides to simplify assembly for stroller manufacturers and aftermarket replacement.

This specialized buckle is not only the go-to choice for original stroller manufacturers (OEM) across Europe, North America, and Asia but also a top-selling aftermarket replacement part for parents and baby product retailers. It is widely integrated into baby strollers, infant carriages, baby walkers, play yards with harnesses, and even portable high chairs-any baby gear that requires a secure, easy-to-use harness fastener. Backed by a 5-year warranty against manufacturing defects, our buckle has become a trusted safety component for leading baby product brands, renowned for its innovation, durability, and uncompromising commitment to infant protection.
