[0003] After searching, it was found that the application number is: CN202022537377.4, a precision thin aluminum strip with a snap-on interface, and its content is: The utility model discloses a precision thin aluminum strip with a snap-on interface, including a connecting plate, an aluminum strip, a fixing bolt and a snap. The connecting plate includes a side plate and an upper plate. Multiple groups of bolt holes are arranged on the inner side of the side plate, and multiple first anti-slip pads are arranged at the bottom end of the upper plate. The snap includes a snap side plate and a snap bottom plate, and the outer wall of the snap side plate is installed with a fixing bolt. The precision thin aluminum strip with a snap-on interface, the first anti-slip pad and the second anti-slip pad can play an anti-slip role, making the aluminum strip more stable between the connecting plate and the snap, and not causing deviation. The first refractory coating and the second refractory coating can prevent the material from heating up or external factors from causing the material to heat up, which may cause a fire, thereby improving the fire resistance and reducing the loss caused by the fire. The connecting plate and the snap-on model are SUS304.
