In particular, it relates to a tensioner capable of tightening the straps that securely bind the box, preventing loosening due to vibration and temperature, ensuring a tight and secure hold between the boxes, and simultaneously providing friction through anti-backlash teeth to prevent slippage when the straps loosen. Background Technology

[0002] In the logistics industry, to prevent boxes from shaking and colliding with each other during transportation, ropes are typically used to bind the boxes together. However, to ensure the ropes adhere well to the boxes and remain taut, the binding personnel usually need to pull the ropes forcefully before tying a knot at the end to secure them. This process is quite laborious and inconvenient. Furthermore, during transportation, the taut ropes can easily loosen due to vibrations and temperature changes between the boxes, thus affecting their securing effect and creating safety hazards.

[0012] The present invention provides a logistics box strap tensioner as follows: The logistics box strap tensioner of the present invention consists of a side tension ring (1), an L-shaped plate (2), an adhesive piece (3), a slot (4), a screw (5), an anti-reverse tooth (6), an angle tension ring (7), a side baffle (8), and an angle boss (9). One side of the L-shaped plate (2) is covered with an adhesive piece (3), which is made of sponge material. The corner of the L-shaped plate (2) protrudes towards the other side of the L-shaped plate (2) to form an angle boss (9). The two sides of the edge of the L-shaped plate (2) protrude towards the other side of the L-shaped plate (2) to form a side baffle (8). A slot (4) is formed between the two side baffles (8). The middle of the slot (4) is... An angular expansion ring (7) is fixedly placed. The angular expansion ring (7) is an elliptical ring structure. One side of the angular expansion ring (7) is fixedly placed on the angular boss (9) by screws (5). An anti-return tooth (6) is fixedly placed on the other side of the angular expansion ring (7). Side expansion rings (1) are fixedly placed on both ends of the slot (4). The side expansion ring (1) is an elliptical ring structure. One side of the side expansion ring (1) is fixedly placed on the L-shaped plate (2) by screws (5). An anti-return tooth (6) is fixedly placed on the other side of the side expansion ring (1). The tips of the anti-return teeth (6) on the two side expansion rings (1) are bent towards the angular boss (9). The tips of the anti-return teeth (6) are rounded. The anti-return teeth (6) are made of elastic material. In use, attach the tensioner to the corner of the logistics box (10) using the adhesive tab (3) on its L-shaped side. Then, select a side tension ring (1) and a corner tension ring (7) of appropriate size and place them in the slot (4), so that the side of the side tension ring (1) and the corner tension ring (7) without the anti-reverse teeth (6) faces into the slot (4). Secure the side tension ring (1) and the corner tension ring (7) in the slot (4) with screws (5), so that the side tension ring (1) The side of the corner expansion ring (7) with the elastic anti-reverse teeth (6) faces outward, and then the strap (11) is used to bind and restrain the box (10). At the same time, the strap (11) should be in contact with the anti-reverse teeth (6) on the side expansion ring (1) and the corner expansion ring (7). The elastic tension of the anti-reverse teeth (6) on the side expansion ring (1) and the corner expansion ring (7) will tighten the strap (11), so that the strap (11) will tighten and bind the logistics box (10). The L-shaped plate (2) has an adhesive strip (3) on one side, which makes it easy to attach the tensioner to the box (10) and prevent the tensioner from shifting or falling off the box (10) when the box (10) vibrates during transportation, thus affecting the fastening effect of the strap (11) on the logistics box (10).

The design of forming a groove (4) between the side baffles (8) on both sides can limit the corner expansion ring (7) and side expansion ring (1) on the groove (4) to prevent the corner expansion ring (7) and side expansion ring (1) from being displaced when the tensioner is subjected to force and shakes. The corner expansion ring (7) is designed with an elliptical ring structure, which can increase the force-bearing surface of the strap (11) at the corner of the box and form protection for the strap (11); The side expansion ring (1) is designed with an elliptical ring structure, which can increase the bearing capacity of the side expansion ring (1) and prevent the side expansion ring (1) at the bottom and side of the tensioner from deforming under force, thereby affecting the fastening effect of the strap (11). The design that the tips of the anti-return teeth (6) on the two side expansion rings (1) are bent towards the corner boss (9) can effectively prevent the strap (11) from being pulled back and forth after it is fixed. The anti-return tooth (6) has a rounded tip design, which can protect the strap (11) and prevent the strap (11) from being punctured by the tip of the anti-return tooth (6), thereby causing the strap (11) to break and fail. The anti-return tooth (6) is designed with elastic material, which can form a multi-ring elastic support structure with high elastic support strength. It can prevent gaps from being generated between the strap (11) and the tensioner when the box (10) vibrates, and can also be evenly stressed when supporting the box (10). The straps (11) that are used to secure the box (10) are tightened to prevent them from loosening due to vibration and temperature. This ensures that the box (10) is tightly secured. At the same time, the anti-backlash teeth (6) provide friction to prevent the straps (11) from slipping when they loosen.
