Heat insulation strip

The utility model relates to a heat insulation strip, which belongs to the field of building doors and windows and comprises a main body, crimping chucks are symmetrically arranged at two ends of the main body, clamping groove structures are arranged on the crimping chucks, aluminum strips are mounted in the clamping groove structures, and non-contact surfaces of the aluminum strips and the crimping chucks are tooth-shaped structures. The aluminum strip is meshed with the compression joint clamping head of the heat insulation strip in a tooth-shaped mode, the tensile strength and the shear strength of the heat insulation strip are improved, meanwhile, the tooth punching procedure of the sectional material is reduced, and the stability of product quality is greatly improved. 本实用新型涉及一种隔热条，属于建筑门窗领域，包括主体，主体两端对称设有压接卡头，压接卡头上设有卡槽结构，卡槽结构内安装有铝条，铝条与压接卡头未接触面呈齿形结构。铝条与隔热条的压接卡头齿形啮合，增加了隔热条的抗拉抗剪强度，同时减少了型材开齿工序，更大的提升了产品质量的稳定性。
