The invention relates to the technical field of fasteners, in particular to a quick-tightening type fastening device and a vehicle, the fastening device comprises a sawtooth piece and a columnar fastener capable of being arranged outside the sawtooth piece in a sleeving mode, the sawtooth piece is provided with multiple circles of sawtooth-shaped first threads, and the bevel edges of the first threads face the side away from the front end of the sawtooth piece; a plurality of elastic clamping pieces are fixed in the columnar fastener in the circumferential direction, second threads matched with the first threads are arranged at the top ends of the multiple elastic clamping pieces, and in the process that the columnar fastener is arranged on the sawtooth piece in a sleeving mode, due to thefact that the elastic clamping pieces have elasticity, the sawtooth piece is not prone to loosening, the elastic clamping piece can skip over the first thread on the sawtooth piece smoothly and quickly and can be clamped on the vertical edge of the sawtooth piece in a one-way mode, and then the fastening installation between the pipeline support and the frame is completed quickly. Therefore, thefastening installation between the pipeline support and the frame can be rapidly completed, so a conventional bolt connection mode is changed, and the assembly efficiency of an automobile production line is greatly improved.
本申请涉及一种速紧式紧固装置及车辆,涉及紧固件技术领域,该紧固装置包括锯齿件和可套设于锯齿件外的柱状紧固件,锯齿件上设有多圈锯齿状的第一螺纹,第一螺纹的斜边朝向远离锯齿件前端的一侧,竖边朝向靠近锯齿件前端的一侧,柱状紧固件内部周向固定有多张弹性卡片,多张弹性卡片的顶端上设有与第一螺纹相匹配的第二螺纹,在柱状紧固件套设锯齿件的过程中,由于弹性卡片具有弹性,使得弹性卡片能较顺利且快速的跳过锯齿件上的第一螺纹,且可单向卡持于锯齿件的竖边上,进而快速完成管路支架与车架之间的紧固安装。因此,本申请可快速完成管路支架与车架之间的紧固安装,改变了传统的螺栓连接方式,大大提升了汽车生产线的装配效率。
