[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 In this embodiment of the utility model, a webbing tensioner for cargo transportation includes a hook 9, which can be fastened to the truck bed and is connected to a tensioning strap 8.

[0032] The ends of the tension band 8 are quilted to form a circular buckle that can be hung on the pivot 7 and the hook 9;

[0033] The rotating shaft 7 has threads at both ends and is installed at the lower end of the retainer 5 by nuts; the twisting roller 4, which is used for winding the webbing 12, passes through the retainer 5 and is also equipped with a ratchet 2; the two ends of the twisting roller 4 are also movably connected to the force-applying member 1.

[0034] The inner side of the force-applying component 1 is also provided with a ratchet pusher 3 for ratchet 2 to actuate.

[0035] By adopting the above technical solution, when using it, first hang the hook 9 on the vehicle body, then pass the webbing 12 that has been wrapped around the goods through the two winches 4, hold the force-applying component 1 and push it upward, hold the ratchet pusher 3 on the inner side of the force-applying component 1 to push the ratchet 2, then the ratchet 2 drives the winches 4 to rotate, which can realize the winding of the webbing 12, thereby realizing the tight binding of the webbing 12 to the goods. The structure is simple and the operation is convenient.

[0036] In this embodiment, there are two winch rollers 4, each winch roller 4 has a D-shaped longitudinal section, and the two ends of the two winch rollers 4 pass through the force-applying member 1 and are fixed by the elastic pin 10.

[0037] By adopting the above technical solution, there is a gap between the two twisting rollers 4 so that the webbing 12 can pass through. When the twisting rollers 4 rotate, the webbing 12 can be twisted.

[0038] In this embodiment, the ratchet 2 has a crossbar that is engaged between the two winches 4.

[0039] By adopting the above technical solution, the crossbar in the middle of the ratchet 2 has a pushing function on the two rollers 4, and can drive the two rollers 4 to rotate when the ratchet 2 rotates.

[0040] In this embodiment, slots 11 are provided on both sides of the force-applying member 1; a ratchet pusher 3 is slidably connected in the slots 11. A sliding groove is provided in the retaining member 5, and a locking plate 6 for locking the ratchet 2 is slidably connected in the sliding groove. The locking plate 6 is convex, and the protruding end is inserted into the groove on the inner side of the retaining member 5, and a spring 14 is also provided on the outside of the protruding end of the locking plate 6.

[0041] By adopting the above technical solution, the ratchet pusher 3 is installed in the slots 11 opened on both sides of the force-applying member 1. When the force-applying member 1 rotates, the ratchet pusher 3 can push the ratchet 2 to rotate.

[0042] The ratchet pusher 3 is slidably connected in the slot 11. When the ratchet pusher 3 rotates in the opposite direction of the ratchet 2, the ratchet 2 can be pushed. At this time, the arc surface of the ratchet 2 presses down on the blocking plate 6. When the blocking plate 6 is between the two ratchet teeth, it can block the ratchet teeth under the push of the spring 14. At this time, the ratchet 2 is in a locked state, and the ratchet 2 cannot rotate in the opposite direction.

[0043] At this point, if the ratchet pusher 3 is rotated clockwise toward the ratchet 2, the ratchet 2 will remain stationary, so that the ratchet pusher 3 can apply force again.

[0044] The force-applying member 1 has protrusions 13 on both sides near the end of the retaining member 5.

[0045] By adopting the above technical solution, when the tension of the webbing 12 is released, the force-applying member 1 is pushed upward, so that the force-applying member 1 and the retaining member 5 are in a straight line. At this time, the protrusion 13 presses down on the blocking plate 6, and the blocking plate 6 disengages from the ratchet 2. Then the ratchet pusher 3 is pulled upward. At this time, the ratchet 2 loses all constraints and can rotate in the opposite direction, which facilitates the loosening of the webbing 12.

[0046] The working principle of this utility model is as follows: When in use, first hang the hook 9 on the vehicle body, then pass the webbing 12 that has been wrapped around the goods through the two rollers 4, push the force application component 1 upward by hand, and push the ratchet push component 3 on the inner side of the force application component 1 to push the ratchet 2. The ratchet 2 will drive the rollers 4 to rotate, which can realize the wrapping of the webbing 12, thereby realizing the tight binding of the webbing 12 to the goods.

[0047] When the ratchet pusher 3 rotates in the reverse direction towards the ratchet 2, the ratchet 2 can be pushed. At this time, the arc surface of the ratchet teeth of the ratchet 2 presses down on the blocking plate 6. When the blocking plate 6 is between the two ratchet teeth, it can block the ratchet teeth under the push of the spring 14. At this time, the ratchet 2 is in a locked state and cannot rotate in the reverse direction. Then, when the ratchet pusher 3 is rotated in the forward direction towards the ratchet 2, the ratchet 2 will not move, so that the ratchet pusher 3 can apply force again.

[0048] When the tension on the webbing 12 is released, the force-applying member 1 is pushed upward so that the force-applying member 1 and the retaining member 5 are in a straight line. At this time, the protrusion 13 presses down on the blocking plate 6, and the blocking plate 6 disengages from the ratchet teeth of the ratchet 2. Then the ratchet pusher 3 is pulled upward. At this time, the ratchet 2 loses all constraints and can rotate in the opposite direction, which facilitates the loosening of the webbing 12.
