Technical Field

[0001] The utility model relates to the technical field of webbings, in particular to a webbing which is convenient for adjusting tightness. Background Art

[0002] Ribbon is made from a variety of yarns into narrow or tubular fabrics. Ribbon fabrics come in a wide variety of varieties and are widely used in clothing, footwear, luggage, industry, agriculture, military supplies, transportation, and other industries. Ribbon materials have gradually evolved to include nylon, vinylon, polyester, polypropylene, spandex, and viscose, resulting in three main fabrication techniques: weaving, knitting, and knitting. Fabric structures include plain, twill, satin, jacquard, double-layer, multi-layer, tubular, and combined weaves.

[0003] Currently, backpack webbing is typically tightened by inserting it through a buckle to accommodate different user needs. However, this method often results in the webbing automatically becoming loose along the buckle due to the jolting movement of the backpack. Therefore, a webbing that is easily adjustable in tension is provided to address this issue. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please refer to Figure 1-Figure 5 The utility model provides a webbing for adjusting the tightness, comprising: an elastic end 1 of the webbing and a fixed end 2 of the webbing, a buckle frame 3 for adjusting the tightness of the webbing connected between the elastic end 1 and the fixed end 2 of the webbing, the buckle frame 3 is located on one side of the elastic end 1 of the webbing and is provided with an automatic clamping mechanism, the automatic clamping mechanism comprises a clamping column 5, a shaft rod 6, a torsion spring 7, and a first bayonet 8, the upper and lower ends of the clamping column 5 are fixedly connected to the shaft rod 6, the torsion spring 7 is sleeved on the outer side of the shaft rod 6, and the first bayonet 8 is provided on one side of the clamping column 5.

[0023] Combine Figure 2 and Figure 3 As shown, a first winding roller 10 is fixedly connected to the side of the strap buckle frame 3 near the elastic end 1 of the webbing, and a second winding roller 11 is fixedly connected to the side of the strap buckle frame 3 near the fixed end 2 of the webbing. The strap buckle frame 3 is provided with an axial hole 4 on the side facing the shaft rod 6. There are two axial holes 4. The shaft rod 6 is connected by rotation inside the axial hole 4, so that the torsion spring 7 always maintains the action of twisting the shaft rod 6, and then the first bayonet 8 on the clamping column 5 is clamped on the outside of the elastic end 1 of the webbing, effectively preventing the elastic end 1 of the webbing from loosening.

[0024] Combine Figure 4As shown, the clamping column 5 is a multi-prism structure, and the buckle frame 3 is provided with a second clamping hole 9 on the side facing the first clamping hole 8. One end of the elastic end 1 of the webbing passes around the first winding roller 10 and passes through the first clamping hole 8 and the second clamping hole 9. The second clamping hole 9 is convenient for cooperating with the first clamping hole 8 to clamp the elastic end 1 of the webbing passing through. One end of the fixed end 2 of the webbing passes around the second winding roller 11 and is folded and sewn. The first winding roller 10 and the second winding roller 11 are both provided with anti-slip stripes on the outer side of the circumference. The anti-slip stripes are longitudinally distributed on the outer side of the first winding roller 10 and the second winding roller 11. The outer side of the elastic end 1 of the webbing and the fixed end 2 of the webbing are provided with textures, and the anti-slip stripes can effectively increase the friction between the webbing and the webbing.

[0025] Specifically, when the present invention is used, the fixed end 2 of the webbing passes around the second winding roller 11 and is sewn and fixed. Then, the elastic end 1 of the webbing passes around the first winding roller 10 and passes through the first bayonet 8 and the second bayonet 9. If it is necessary to tighten and adjust the elastic end 1 of the webbing, the end of the elastic end 1 of the webbing between the first bayonet 8 and the second bayonet 9 can be dragged outward to tighten it. When it is necessary to loosen the elastic end 1 of the webbing, the buckle frame 3 can be lifted and placed perpendicular to the elastic end 1 of the webbing, and then the rotating clamping column 5 can be moved to make the first bayonet 8 on the clamping column 5 away from the elastic end 1 of the webbing, and then the elastic end 1 of the webbing can be loosened.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
