Model: CK643
Material: POM
Product specifications: 77mm
Modifiers: durable, multifunctional, convenient, safe and reliable
Usage: Mainly used for connecting and opening backpacks, outdoor equipment, luggage and other items, achieving quick assembly and disassembly, and can also be used in some scenarios that require temporary fixation or quick connection.
This compact, precision-molded buckle is made expressly for infant and toddler product applications where safety, ease of use, and durability matter. The CK643 combines a male tongue and female socket with an intentional locking geometry so a caregiver can secure a strap in a single, confident motion — and release it just as simply when needed. The POM construction yields a smooth, satiny surface that feels cool under the fingertips and resists abrasion, keeping the buckle looking and performing like new through daily handling. At 77 mm it fits medium-width webbings commonly found on children’s backpacks and safety accessories. The result for caregivers: less fumbling, faster adjustments, and a quiet, predictable “click” that signals a secure connection.
CK643 is sized and engineered to solve everyday friction points for caregivers and product designers:
One-motion fastening: Saves time and reduces frustration — particularly helpful during hurried moments like school drop-offs.
Gentle, predictable release: Reduces accidental unbuckling while still allowing quick access when needed.
Durable POM material: Long-term resistance to wear and common household exposures means fewer replacements and lower lifecycle cost.
Child-friendly ergonomics: Smooth edges and a low profile minimize snagging and are comfortable against fabric and skin.
Versatile compatibility: 77 mm size works with many standard webbings for seamless integration into existing designs.
POM is chosen for stiffness and dimensional stability.
Good wear resistance under frequent fastening cycles.
Maintains shape in normal temperature ranges; resists small impacts.
A male tongue locks into a female socket with positive engagement.
Locking geometry minimizes accidental release under normal loads.
Low-profile design reduces snagging on clothing or fabric.
Designed for fast, repeatable operations by caregivers of all ages.
Smooth edges and a satiny finish are comfortable to touch.
Audible “click” confirms secure closure without visual check.
77 mm width addresses many children’s product webbings.
Simplifies SKU selection for manufacturers.
Useful for retrofit or new-product designs alike.
Targeted at backpacks, children’s safety items, luggage and outdoor gear.
For safety-critical consumer goods (e.g., car seats), final assemblies should be tested to local safety standards.
Widely used in outdoor products (such as hiking bags, camping equipment), luggage (such as suitcases, backpacks), children's products (such as children's backpacks, safety seat accessories) and other fields.
It consists of a male buckle and a female buckle. The male buckle has a tongue structure, and the female buckle has a corresponding slot and locking device. By inserting the tongue into the slot and locking it, the connection and fixation are achieved. The structure is simple but the buckle is stable.
