Document Type and Number:
WIPO Patent Application WO/2020/057037
Kind Code:
A1
Abstract:
A manual belt-winding safety tensioning device for an automobile, comprising a main machine part (1), a belt-winding part (2) and a first binding belt (3), wherein the belt-winding part (2) comprises a belt-winding box (21), a belt-winding shaft (22) and a belt-winding hand wheel (23); the belt-winding shaft (22) penetrates the belt-winding box (21); the belt-winding hand wheel (23) is arranged on the outer side of the belt-winding box (21) and is connected to the belt-winding shaft (22); the inner end of the first binding belt (3) is arranged on the belt-winding shaft (22); the belt-winding hand wheel (23) may rotate outwards and inwards, the outward rotation may drive the belt-winding shaft (22) to rotate synchronously so that the first binding belt (3) is wound into the belt-winding box (21), and the inward rotation may lock the belt-winding shaft (22) on the belt-winding box (21) so that the wound first binding belt (3) may be prevented from loosening. The present manual belt-winding safety tensioning device for an automobile has the following advantages: the belt-winding hand wheel (23) of the manual belt-winding safety tensioning device for an automobile may be screwed in and out, the outward rotation of the belt-winding hand wheel (23) may wind the first binding belt (3) into the belt-winding box (21), and the inward rotation of the belt-winding hand wheel (23) may lock the belt-winding shaft (22) and prevent the same from rotating, thereby preventing the wound belt from loosening. In addition, the first binding belt (3) penetrates the main machine and is restricted in a belt penetrating groove (221), which may prevent the belt from being pulled out accidentally.
