Description

Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to an interval-release tensioner. Background Art

[0002] Tensioners are used to secure goods during transportation, movement, shipment, or storage. Once locked, they prevent them from falling off, are safe and reliable, lightweight, easy to operate, and protect objects from damage. They are used to reinforce steel formwork and compressed wood panels, primarily for tensioning. They are used to tighten with the device and then secure with a butterfly buckle. They are easy to operate and can improve calibration efficiency by over ten times compared to other tensioning methods.

[0003] Existing technology, such as: CN214824760U is a new type of tensioner. This new type of tensioner improves the strength of the cutting assembly through the design of double ratchet gears, thereby improving the mechanical strength and applicable scope of the tensioner. Both ratchet gears adopt a design of 11 gear teeth. Compared with the traditional ten-tooth design, the protruding height of the gear teeth is smaller, which makes it easier to twist the tensioning handle. At the same time, the ratchet gear is stronger and has greater bearing capacity. A protruding ring is provided on the inner and outer walls of the tensioner body and the tensioning handle. After the protruding ring is provided, the contact area between the tensioner body and the tensioning handle becomes smaller, reducing the sliding friction. The tensioning handle is more flexible to operate, which can increase the force effect of the cutting assembly and improve the stability and durability of the cutting assembly. That is, the entire new tensioner has high strength, good stability and durability, and a wider range of applications.

[0004] However, this tensioner still has certain shortcomings during use. Since the tensioner has only two states: tightened and completely released, the cargo may be unevenly stacked, tilted due to vibration and bumps, and other safety hazards. Suddenly releasing the tensioner completely during unloading may easily cause the cargo to collapse, thereby causing unnecessary personal and property losses, and is therefore subject to limitations on applicable occasions.
