Technical Field

[0001] The utility model relates to the technical field related to automobile tensioners, in particular to an automobile tensioner provided with an automatic winding structure. Background Art

[0002] When transporting a car, large transport vehicles will vibrate and bump. In order to avoid scratches caused by the vibration and bumps, the car needs to be fixed on the deck. The tires of the car are the parts that can be easily moved and can be fixed without damaging the car. Tire tie-down straps are gradually being widely used due to their small size, light weight, simple operation, safety, reliability, and easy portability. Therefore, a car tensioner is needed.

[0003] When the car tensioner is in use, the tail hook and the binding belt at the tail are usually placed randomly. When the car tensioner is stored, the tail hook is not properly handled, which can easily cause the tail hook to scratch the user's hand during use.

[0004] In order to overcome the above-mentioned drawbacks, reference may be made to the prior art (Announcement No. CN202624038U discloses an automobile tensioner, which was published on December 26, 2012). During the storage process, the automobile tensioner secures one end of the tensioning belt II to the hook II and winds the other end around the belt winding rod, thereby achieving the purpose of storage.

[0005] Although the existing technology can achieve the purpose of storing the tail hook and the binding belt at the tail, it requires the staff to wrap them in circles, which is cumbersome to operate, and there is no mechanism for automatically rewinding the binding belt and the hook at the tail to assist in the processing.

[0006] Therefore, we have proposed an automobile tensioner with an automatic winding structure that can well solve the above problems. Utility Model Content
