Description

Technical Field

[0001] The utility model relates to a quick-release belt tensioner. Background Art

[0002] When a transport vehicle is carrying goods, in order to prevent the stacked goods from shaking or falling during transportation, a hand puller is used to fix them. The hand puller reciprocates to pull the first tensioner drive gear and simultaneously drives the take-up shaft to rotate to wind the tether into the take-up shaft. At the same time, the tensioner can limit the movement of the gear in one direction to fix the goods. When the tether is untied, the part of the tensioner that limits the gear is detached from the gear, so that the gear and the take-up shaft can rotate freely without restriction. However, since the take-up shaft is made of two semi-cylinders, the irregular shape has a relatively large friction with the surrounding parts when rotating, resulting in problems such as it is not easy to loosen the tether or it requires a lot of force to loosen the tether.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The second tensioning member 2 includes two second connecting plates 21 arranged opposite to each other and a connecting plate 22 arranged at the bottom of the front end of the second connecting plate 21. Support rods are arranged at the top and bottom ends of the second connecting plate 21. The first tether (not shown in the figure) is connected to the support rod at the top. A second connecting port 24 is arranged near the tail end of the second connecting plate 21. The second connecting port 24 is circular and has the same size as the first connecting port 14 and is located opposite to it. A rectangular second opening 23 is arranged near the top end of the second connecting plate 21. A second clamping member 5 is connected to the second opening 23. Second limiting protrusions 51 are arranged at both ends of the second clamping member 5. The two second limiting protrusions 51 are respectively engaged in the two second openings 23 and protrude on both sides of the second tensioning member 2. The width of the second limiting protrusion 51 is narrower than the width of the second opening 23. A limiting hole 221 is extended upward from the front end of the connecting plate 22, a limiting protrusion 52 is provided at the top end of the second clamping member 5, the limiting protrusion 52 is arranged in the limiting hole 221, and the second clamping member 5 is provided with triangular recessed portions at both ends of the limiting protrusion 52, and both sides of the limiting hole 221 are arranged in the middle of the triangular recessed portions.

[0023] The first tensioning member 1 and the second tensioning member 2 are connected by the first connecting port 14 and the second connecting port 24 using the winding shaft 6. The winding shaft 6 includes two semi-cylinders. The rectangular surfaces of the two semi-cylinders are arranged opposite to each other and there is a gap in the middle, and the gap is convenient for the lace to pass through; the first connecting port 14 of the first tensioning member 1 is located on the outside of the second connecting port 24 of the second tensioning member 2, the second limiting protrusion 51 is located at the recessed portion 16 of the first tensioning member 1, the protrusion 15 is against one side of the second limiting protrusion 51, and the first limiting protrusion 41 is located at the upper end of the second limiting protrusion 51.

[0024] Two gear sets 3 are provided at both ends of the tape winding shaft 6. The gear sets 3 are provided with a sleeve 31, two limiting gears 32 arranged in parallel and a fixing piece 33 in sequence from the inside to the outside. The sleeve 31 is a T-shaped sleeve composed of a tube body and an outer edge, and is sleeved on the outer wall of the tape winding shaft 6. The tube body of the sleeve 31 is arranged inside the first connecting port 14 and the second connecting port 24 to avoid direct contact between the first connecting port 14 and the second connecting port 24 and the tape winding shaft 6. The outer edge portion is arranged on the outer periphery of the first connecting port 14. Two semicircular hollows are relatively arranged on the two limiting gears 32, which cooperate with the semi-cylinders of the tape winding shaft 6 to pass the limiting gears 32 through the two semi-cylinders and sleeve them on the tape winding shaft 6. Clamps in opposite directions are provided at both ends of the fixing piece 33. The fixing piece 33 is arranged in the gap of the tape winding shaft 6, and the clamps in opposite directions at both ends clamp it on the tape winding shaft 6.

[0025] The limiting gear 32 includes a helical tooth surface 321 and a flat tooth surface 322 . When the limiting gear 32 is fixed on the tape reel 6 , the second limiting protrusion 51 abuts against the flat tooth surface 322 , and the first limiting protrusion 41 also abuts against the flat tooth surface 322 .

[0026] When in use, first fix one end of the first tether, pass the second tether that wraps around the cargo through the gap on the outside of the take-up shaft 6, and pass it out from one side of the take-up shaft 6, and then use the first handle 12 to pull the first tensioning member 1 upward in a clockwise direction. At this time, the first limiting protrusion 41 will move upward along the bevel tooth surface 321 of the limiting gear 32, and the take-up shaft 6 will also be driven to rotate in the clockwise direction; then use the first handle 12 to pull the first tensioning member 1 downward in a counterclockwise direction. At this time, the limiting gear 32 will be driven to move counterclockwise, and the bevel tooth surface 321 can squeeze the second limiting protrusion 51 backward. Then it passes through the second limiting protrusion 51. At this time, the winding shaft 6 is driven to rotate counterclockwise, and the second tether will be partially wound by the winding shaft 6. When the first tensioning member 1 moves to the bottom, the recessed portion 16 limits the position of the second limiting protrusion 51, and the second limiting protrusion 51 is again against the flat tooth surface 322. Repeatedly pulling the first tensioning member 1 back and forth can fasten the cargo with the second tether; when the oblique tooth surface 321 pushes the second limiting protrusion 51 backward, the limiting protrusion 52 and the limiting hole 221 can prevent the second limiting protrusion 51 from abutting against one end of the second opening 23 and wearing out.

[0027] When the second tether needs to be loosened, the first tensioning member 1 is separated from the second tensioning member 2, the recessed portion 16 is no longer located at the second limiting protrusion 51, and the second handle 42 is lifted up to allow the first limiting protrusion 41 to leave the flat tooth surface 322 of the limiting gear 32. The limiting gear 32 is not restricted by the first limiting protrusion 41 and the second limiting protrusion 51, and the winding shaft 6 can rotate freely. Since there is a sleeve 31 between the winding shaft 6 and the first connecting port 14 and the second connecting port 24, the resistance between the winding shaft 6 and the first connecting port 14 and the second connecting port 24 is smaller during rotation, and the rotation is smoother. At this time, the second tether can be removed.

[0028] Example 2: Figure 4 As shown, the front end of the connecting plate 22 is extended upward to be provided with two limiting holes 221, and the top end of the second clamping member 5 is oppositely provided with two limiting protrusions 52, and the limiting holes 221 are cylindrical in shape, and the limiting protrusions 52 are triangular in shape.

[0029] Example 3: Figure 5 As shown, a spring is sleeved on the limiting protrusion 52 , one end of the spring abuts against the limiting hole 221 , and the other end abuts against the triangular recessed portion of the second clamping member 5 .

[0030] The utility model quick release belt tensioner sets a sleeve 31 between the first connecting port 14 and the second connecting port 24 and the belt reel 6. When the second tether is untied, the resistance between the belt reel 6 and the first connecting port 14 and the second connecting port 24 is smaller during rotation, and the rotation is smoother, so that untying the second tether can be more labor-saving.
