Description

Technical Field

[0001] The utility model relates to the technical field of lifting belts, in particular to an adjustable flat lifting belt. Background Art

[0002] Conventional lifting belts (synthetic fiber lifting belts) are generally made of high-strength polyester filaments. They have multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, non-conductive, and non-corrosive (no harm to the human body), and are widely used in various fields. There are many types of lifting belts. Conventional lifting belts (according to the appearance of the lifting belts) are divided into four categories: annular core-through, annular flat, double-eye core-through, and double-eye flat. Among them, flat lifting belts are more economical and practical. They can continuously change the point of force and have a variety of uses.

[0003] For example, the utility model patent with patent number CN220537298U discloses a flat lifting belt, including a belt body, both ends of which are provided with eyes, and two clamping members are slidably connected to the belt body, and the clamping members include an upper pressure plate and a lower pressure plate located on both sides of the belt body, and butterfly bolts pass through the upper pressure plate and the lower pressure plate, and the butterfly bolts are used to adjust the distance between the upper pressure plate and the lower pressure plate.

[0004] There are at least the following problems in the above patent: first, the handle on the head of the butterfly bolt is outward, which is easy to be accidentally touched before, during and after use, causing the butterfly bolt to loosen, affecting the upper and lower pressure plates to clamp the belt body, thereby affecting the lifting and even causing accidents; second, there is a gap between the limit blocks between the upper and lower pressure plates during the adjustment process, and the edge of the belt body is easily misplaced and clamped between the two sets of limit blocks, affecting the normal clamping of the upper and lower pressure plates on the belt body. Utility Model Content

The slide plate 21 is flush with the side wall of the limit plate 31, and the belt body 1 is slidably arranged between the two groups of limit plates 31.

[0024] By setting the upper pressing plate 2 and the lower pressing plate 3, the belt body 1 can be clamped to ensure that the size of the ring eyes at both ends of the belt body 1 is stable and will not change during the lifting process; by setting the U-shaped handle 5, it is convenient for the staff to turn the bolt 4, adjust the spacing between the upper pressing plate 2 and the lower pressing plate 3, loosen the belt body 1, and adjust the positions of the upper pressing plate 2 and the lower pressing plate 3 on the belt body 1, thereby adjusting the size of the ring eyes at both ends of the belt body 1; by setting the damping shaft 6, the U-shaped handle 5 can be rotated and can be fixed at any angle so that the U-shaped handle 5 can be close to the upper pressing plate 2 without shaking, avoiding accidental touching of the U-shaped handle 5 to cause the bolt 4 to loosen; by setting the slide plate 21, the limit plate 31 and the slide groove 32, it can be ensured that the upper and lower parts of the belt body 1 are not misaligned, and are always neatly located between the slide plate 21 and the limit plate 31. In the process of tightening the bolt 4, the slide plate 21 and the limit plate 31 will not clamp the edge of the belt body 1, ensuring that the upper and lower pressing plates 2 and the lower pressing plates 3 can stably clamp the belt body 1.

[0025] like Figure 1 and Figure 2 As shown, a first protective tube 22 is provided on the top of the upper pressing plate 2, and the head of the bolt 4 and the U-shaped handle 5 are arranged in the first protective tube 22. By providing the first protective tube 22, the head of the bolt 4 and the U-shaped handle 5 can be further protected to prevent the bolt 4 from loosening due to accidental touch.

[0026] like Figure 2 As shown, a rubber gasket 23 is provided on the inner side of the first protective tube 22, and the U-shaped handle 5 abuts against the rubber gasket 23. By providing the rubber gasket 23, the U-shaped handle 5 can be squeezed, further ensuring that the U-shaped handle 5 is closely attached to the upper pressing plate 2 and will not shake and turn out.

[0027] A second protective tube is provided at the bottom of the lower pressing plate 3, and the second protective tube is identical to the first protective tube 22, and the bottom of the screw rod of the bolt 4 is arranged in the second protective tube. By providing the second protective tube, the bottom of the screw rod of the bolt 4 can be protected and the screw rod of the bolt 4 can be prevented from scratching foreign objects.

[0028] like Figure 1 and Figure 2 As shown, both the first protection tube 22 and the second protection tube are detachably provided with a protection cover 7. By providing the protection cover 7, the first protection tube 22 and the second protection tube can be closed, and the bolt 4 and the U-shaped handle 5 can be further protected.

By providing the folding plates 8, the bolts 4 between the upper pressing plate 2 and the lower pressing plate 3 can be protected from being hit by other objects.

[0030] When adjusting, the staff first opens the protective cover 7 on the upper pressing plate 2, and then rotates the U-shaped handle 5 out of the first protective tube 22 by hand or with a tool, and then rotates the U-shaped handle 5 to loosen the bolt 4, so that the upper pressing plate 2 and the lower pressing plate 3 are released from the belt body 1. At this time, the middle part of the folding plate 8 will be retracted as the distance between the upper pressing plate 2 and the lower pressing plate 3 increases, and the slide plate 21 slides in the slide groove 32 of the limiting plate 31. The slide plate 21 will not slide out of the slide groove 32. Since the slide plate 21 is flush with the side wall of the limiting plate 31, The upper and lower parts of the belt body 1 are kept neat and not misaligned; then the staff can slide the pressing plate 2 and the lower pressing plate 3 on the belt body 1 to adjust the position, thereby adjusting the size of the eye; after determining the position, rotate the U-shaped handle 5 to tighten the bolt 4, so that the upper pressing plate 2 and the lower pressing plate 3 press the belt body 1, and then rotate the U-shaped handle 5 into the first protective tube 22, so that the U-shaped handle 5 is attached to the upper pressing plate 2 and abuts against the rubber gasket 23 to fix the position; finally, cover the protective cover 7 to complete the adjustment.
