A safety tensioning device for automobile comprises a winding assembly disposed on the base and driven by a main shaft, the winding assembly and a coil spring; a stop plate and a pressing plate disposed respectively at the front end and the rear end of the base; a driving pawl is rotatably connected to the handle. The handle is pivoted to the base and is capable of rotating about the main shaft; the base has three operating regions on the top of the base: a tensioning region, a working region and a release region, the three operating regions cooperate with the limiting block of the driving pawl. The present invention can automatically wind the first bundling strap when the first bundling strap is loose due to jolts in the operating state, so that the first bundling strap is always kept in the tensioned state, thereby preventing unhooking and greatly improving the use safety.

Tensioning device

A safety tensioning device includes a base, a handle, a winding mechanism and a first bundling strap. The first bundling strap is disposed on the main rotating shaft and the winding mechanism. The winding mechanism includes a box, a coil spring component and a winding shaft passing through the box with two ends exposed out of the box. One end of the winding shaft is attached to the coil spring component, a centrifugal self-locking mechanism to stop the winding shaft winding when a rotation speed is too fast, is attached to another end of the winding shaft.

A safety tensioning device for automobile has a main body, a winding mechanism and a first strap; wherein, the winding mechanism has a frame, a winding shaft and a winding wheel; the winding shaft runs through the two opposite walls of the frame, an inner end of the first strap is connected to the winding shaft; when the winding wheel rotates outward causes the winding shaft to rotate synchronously so that the first strap is wound inside the frame, and, when the winding wheel rotates inward causes the winding shaft to be locked to the frame, preventing the first strap from unwinding. The present invention has the following advantages, the winding wheel can be rotated inward or outward. In addition, the first strap passes through the device body and is limited on the band slot, so the strap can be prevented from being pulled out accidently.
