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.

The present invention discloses an automatically retractable automobile towing device, which comprises a hollow housing (), two coil springs (), a winding shaft () and a towing belt (). The housing () has a mounting chamber () and two first through holes (). The winding shaft () is rotatably assembled in the mounting chamber () and can maintain the towing belt (). The towing belt () is able to extend and retract with rotation of the winding shaft (). The present invention further discloses a limiting mechanism. In the present invention, the stability of automobile towing is improved, the deviation of the towing belt during the retraction process is avoided so that the towing belt is allowed to stretch or retract smoothly.

A multi-stage transmission tensioning device for automobile safety comprises a base group (), a handle group () and a multi-stage transmission group (); the multi-stage transmission group () comprises a transmission shaft () for pivoting both with the base of the base group () and the handle of the handle group (), a main rotating shaft () used for winding a long strap (), and a transmission wheel fixed on the transmission shaft (). A fairly large binding force on the straps ultimately can be achieved from a small force applied to the handle by multiple conversions. Different binding forces in the case of applying the same handle force may be got via the increase or decrease of the transmission stages and the change of the transmission ratio of the transmission at all stages.

The ratchet buckle for tightening a strap under a ratchet action provides a lock to positively prevent the ratchet buckle from inadvertently releasing the strap. The lock requires a removable handle to be installed on the ratchet buckle before the lock can be released. The removable handle extends the ratchet buckle crank arm for increased leverage in exercising the ratchet buckle and when removed reduces the overall size of the ratchet buckle and eliminates a crank arm portion that would otherwise extend beyond the ratchet buckle base.

Lockable ratchet buckle

The ratchet buckle for tightening a strap under a ratchet action provides a retention arm that constrains folded excess strap to the buckle to prevent it from flapping free during transport of cargo that the strap secures. A guard is provided outside a crank arm that is rotatably journaled to a base by a spindle on its forward end. The crank arm is secured to the guard intermediate the length of the guard with the guard extending rearward of the crank arm. The guard thus covers a ratchet wheel and the crank arm and with the crank arm forms an effective double-layered crank arm. The retention arm is rotatable on a handle shaft mounted to the guard rearward end, biased down onto folded excess strap.

The retractable tie-down provides an adjustable strap under control of a rotation brake during retraction and pay-out. The rotation brake impedes rotation of a spool on which the strap is wrapped and unwrapped during retraction and pay-out of the strap as the tie-down operates in one of either a pay-out mode or a retraction mode. Thus, the rate of retraction of the strap is user-controlled through the rotation brake. The tie-down is provided with a lanyard issuing from rearward from the tie-down and a strap issuing forward from the tie-down for securement without direct, or positive attachment of the tie down to an anchor point, such as a chassis of a vehicle or the like.

A frame constitutes the main part of a gradually released tension machine, which is a kind of tool for tensioning and releasing cargo binding strips by hand, and which also comprises a ratchet and an operating handle. On the edge of the frame is a locking slot and a loosening slot, and a releasing slot near the loosening slot. The frame also has a slow-release device comprising the releasing slot and a sliding gear which is used in combination with the ratchet of the tension machine and is rotatably fixed in proximity to the releasing slot, such that the tip of the sliding gear overlaps the releasing slot and is substantially even with the teeth of the ratchet. The frame is simple and can be easily manufactured. Utilizing this kind of frame, the releasing effect is much better, and the tension machine has greatly improved reliability and safety.
