The invention relates to the technical field of automobile tires, and discloses an automobile self-rescue escape device convenient to install and carry, which comprises a disc. The outer part of the disc is fixedly connected with one end of an upper supporting column; the other end of the upper supporting column is rotationally connected with a lower supporting column; threads are arranged on theouter portion of the upper supporting column. The upper supporting column is sleeved with a threaded sleeve. Through holes are formed in the bottom of the front face of the upper supporting column andthe top of the front face of the lower supporting column, connecting shafts are inserted into the through holes, circular grooves are formed in the bottom of the upper supporting column and the top of the lower supporting column, connecting blocks are fixedly connected to the tops and the bottoms of the circular grooves, and an arc-shaped spring is fixedly connected between the two connecting blocks. The threaded sleeve is rotated to the position, close to the disc, of the upper supporting column, the arc-shaped spring of the circular groove exerts downward elastic force on the lower supporting column, the lower supporting column can rotate rightwards around the rotating shaft, and therefore the effects of automatic retracting and convenient carrying are achieved.

    本发明涉及车用轮胎技术领域,且公开了一种便于安装携带的汽车自救脱困器,包括圆盘,所述圆盘的外部固定连接有上支撑柱的一端,所述上支撑柱的另一端转动连接有下支撑柱,所述上支撑柱的外部设置有螺纹,所述上支撑柱的外部套接有螺纹套,所述上支撑柱正面的底部和下支撑柱正面的顶部开设有通孔,所述通孔内插接有连接轴,所述上支撑柱的底部和下支撑柱的顶部开设有圆形槽,所述圆形槽的顶部和底部固定连接有连接块,两个所述连接块之间固定连接有弧形弹簧。通过将螺纹套转至上支撑柱靠近圆盘的位置,圆形槽的弧形弹簧给下支撑柱一个向下的弹力,下支撑柱会围绕转动轴向右转动,从而达到了自动收回、便于携带的效果。
