Description

Technical Field

[0001] The utility model relates to the technical field of webbings, in particular to a tear-resistant webbing. Background Art

[0002] As an important material widely used in clothing, shoes, bags, industry, agriculture, military supplies, transportation and other fields, its performance and quality are directly related to the durability and safety of the product. Ribbon is usually woven from various fiber or yarn raw materials, and its structure is diverse, including narrow fabrics and tubular fabrics. With the continuous advancement of technology, the design and manufacturing technology of ribbons are also continuously optimized to meet the diverse needs of different industries for strength, wear resistance, tear resistance and appearance.

[0003] Although modern webbing has made significant progress in strength and durability, tear resistance remains a key technical challenge. Once a tear occurs, it tends to propagate very quickly, especially in areas of concentrated stress or under impact, and may quickly spread to the entire webbing, causing complete failure. This phenomenon is particularly dangerous in high-risk application scenarios such as aerial work safety belts and mountaineering equipment. Once the tear spreads, it will seriously threaten the safety of the user. Utility Model Content

[0004] The purpose of the utility model is to provide a tear-resistant webbing to solve the problems raised in the above background technology.

[0006] Preferably, the number of the inner wires is two.

[0007] Preferably, the inner wire is made of nylon fiber or Kevlar fiber.

[0008] Preferably, the outer protective layer is made of polyester fiber or polypropylene fiber.

[0009] Preferably, the outer protective layer is connected to the inner wires by a flat knot to fix the plurality of inner wires together.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model combines a high-strength inner wire with a wear-resistant outer protective layer and firmly connects them by a flat knot, so that the webbing has excellent tear resistance and wear resistance during use. The use of the flat knot not only enhances the structural stability of the webbing, but also allows the outer protective layer to participate in the transmission and distribution of force, effectively extending the service life of the webbing and ensuring its reliability in complex environments.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be fixed connection, setting, or detachable connection, setting, or integrated connection, setting. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0020] See also Figure 1-3 As shown, the utility model provides a technical solution for a tear-resistant webbing: a tear-resistant webbing, including a webbing body 1, the webbing body 1 is made of a plurality of webbing thread groups 2 by flat weaving, the webbing thread groups 2 include a plurality of inner threads 3, and an outer protective layer 4 is arranged on the outer side of the inner threads 3.

[0021] In the above design, the inner wires 3 are the main load-bearing wires in the webbing wire group 2. They are located in the longitudinal direction of the webbing and directly bear the tension applied by the outside world. Multiple inner wires 3 work together to appropriately disperse the force when dealing with tearing force to avoid single-wire stress. The main function of the outer protective layer 4 is to provide wear-resistant protection to prevent the inner wire 3 from breaking due to side friction.

[0022] Preferably, the number of inner wires 3 is two, and the material of the inner wires 3 is nylon fiber or Kevlar fiber. The number and material of the inner wires 3 can make the longitudinal direction of the inner wires 3 of the webbing have excellent tear resistance. The material of the outer protective layer 4 is polyester fiber or polypropylene fiber, which can provide excellent wear resistance, thereby protecting the inner wires 3 and improving the durability of the webbing.

[0023] When a single inner wire 3 is subjected to a large stress, it may disperse or slip. In particular, when multiple inner wires 3 work together, if there is no effective fixing method, relative movement may occur between the inner wires 3, thereby reducing the overall strength and stability of the webbing. In order to solve this problem, the present invention proposes a method of connecting the outer protective layer 4 and the inner wire 3 to each other by a square knot, so as to fix several inner wires 3 together.

[0024] Under the action of the square knot, the outer protective layer 4 not only protects the inner line 3, but also further enhances the overall structural stability of the webbing by being closely connected with the inner line 3. The square knot can firmly combine the outer protective layer 4 with the inner line 3, so that the outer protective layer 4 is not only a covering structure, but also participates in the transmission and distribution of force, thereby improving the overall strength of the webbing.

[0025] The working principle of the utility model is as follows:

[0026] When the tear-resistant webbing of this embodiment is in use, the webbing body 1 bears and disperses the external tension through the plurality of webbing wire groups 2 arranged vertically and horizontally. The inner wire 3, as the main load-bearing wire in the webbing wire group 2, is located in the longitudinal direction of the webbing and directly bears the main tension. Since there are two inner wires 3 and they are made of nylon fiber or Kevlar fiber, when dealing with tearing force, multiple inner wires 3 can share the stress together to avoid a single inner wire from breaking due to excessive stress.

[0027] The outer protective layer 4 is coated on the outer side of the inner line 3, and mainly plays the role of wear protection, preventing the inner line 3 from being worn or broken due to side friction. In addition, the outer protective layer 4 is tightly connected to the inner line 3 by a flat knot, so that the outer protective layer 4 not only plays the role of protecting the inner line 3, but also can further improve the overall structural stability of the webbing.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
