• intros：{"brand_intro":"PETZL（佩特兹）是全球高空作业与绳索技术领域的绝对领导者，由法国探险家Fernand Petzl于1975年创立。品牌起源于阿尔卑斯山脉的洞穴探险，创始人将登山与探洞的实战经验转化为极致的安全装备。PETZL坚持法国原产，所有主锁均通过CE与UIAA双重认证，其热处理铝合金工艺与Keylock锁鼻系统（防钩挂）成为行业标杆。品控理念为\"零妥协\"，每把锁出厂前均经过100%拉力测试，在工业攀爬、消防救援、户外探险领域拥有不可撼动的专业地位。","product_intro":"PETZL OK是入门级丝扣主锁中的\"常青树\"，定位为高性价比通用型连接器。核心卖点在于其经典的H型截面设计，在保证强度的同时大幅减重（仅55g），配合Keylock锁鼻技术，有效避免绳索钩挂。适用场景涵盖工业高空作业、攀岩保护站设置、探洞及绳索救援。相比竞品Black Diamond的RockLock，OK锁的丝扣手感更顺滑，且开口尺寸更大（22mm），便于连接多股绳索或扁带。","key_specs":{"材质":"7075铝合金，轻量且耐腐蚀","重量":"55g，同级别最轻之一","开口尺寸":"22mm，兼容多数扁带与绳结","纵向断裂负荷":"25kN，远超EN 362标准","横向断裂负荷":"10kN，满足工业侧向受力要求","认证":"CE EN 362 / UIAA 121"}}
