A combined type plastic buckle for a steering column disclosed in the invention comprises a first buckle and a second buckle, the first buckle is provided with a first flange surface, at least two clamping jaws are arranged at one end of the first flange surface in a protruding mode, and a guide gap is formed between every two adjacent clamping jaws; and a through hole is formed in the first flange surface, and the clamping jaws are distributed around the through hole. The second buckle is provided with a second flange surface, a buckling column is arranged at one end of the second flange surface in a protruding mode, a guide boss is arranged on the outer side wall of the buckling column, the side, away from the second flange surface, of the guide boss is an inclined surface, the buckling column can penetrate through the through hole so that the second buckle can be embedded into the first buckle, and the guide boss slides along the guide gap. Expansion bosses are further arranged at the ends of the buckling columns, and the inner side walls of the clamping jaws contract towards the inner side. According to the invention, the existing bolt and nut connection is replaced by the combined plastic buckle. On the premise of reliably installing and fixing electric appliance parts, the production operation efficiency is improved, and the system cost and weight are reduced to a certain extent.
本发明公开了一种组合式转向管柱用塑料卡扣,包括第一卡扣和第二卡扣,第一卡扣设有第一法兰面,第一法兰面的一端凸设有至少两个卡爪,且相邻卡爪之间设有导向间隙;第一法兰面上开设有通孔,卡爪分布在通孔的周围。第二卡扣设有第二法兰面,第二法兰面的一端凸设有扣合柱,扣合柱上的外侧壁上设有导向凸台,导向凸台远离第二法兰面的一边为斜面,扣合柱能够穿过通孔,以使得第二卡扣嵌入至第一卡扣内,且导向凸台沿着导向间隙滑动;扣合柱的端部还设有膨胀凸台,卡爪的内侧壁均朝向内侧收缩。本发明所通过组合式塑料卡扣取代现有的螺栓螺母连接。可满足电器类零件可靠安装固定的前提下,提高生产作业效率,一定程度降低系统成本和重量。
