TECHNICAL FIELD
[0001] The utility model relates to the technical field of string, especially to a pull rope. BACKGROUND
[0002] The pull rope used on furniture is generally a cross-woven string or a plastic rope. The inner core of the plastic rope used on the existing furniture is made of iron wire or steel wire structure, which has poor softness and is inconvenient to use. The woven string has poor tensile strength and is easy to break. SUMMARY
[0003] In order to solve the technical defects in the background art, the utility model aims to provide a pull rope.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A pull rope comprises a rope body and a core strip. The rope body is internally provided with a circular mounting groove along its length direction, and the core strip is mounted in the mounting groove. The core strip is in a soft silk structure.
[0006] By adopting the above technical scheme, the soft silk wire is arranged in the rope body, which can improve the softness and tensile strength of the pull rope, and the pull rope can quickly return to the initial state after bending. The core strip will not be deformed, thereby prolonging the service life of the pull rope and making it more convenient to use. Moreover, the softness of the pull rope is improved, which is convenient for storage and carrying.
[0007] Further, the core strip is made of cotton wire material, which has a simple structure, low cost and high tensile strength.
[0008] Further, the thickness of the core strip is set to 1800D-2200D, which can ensure the tensile strength of the pull rope.
[0009] Further, the rope body is made of plastic or woven layer structure, which has a simple structure, is convenient to process and is conducive to protecting the core strip.
[0010] Further, the cross-sectional area of the core strip is smaller than that of the mounting groove, which reserves space for the bending and deformation of the core strip, so that the softness is higher and the bending and winding effect is better.
[0011] Further, the core strip and the rope body are extrusion molded, which has high processing efficiency.
[0012] In summary, the utility model has the following advantages:
[0013] The utility model discloses a softness silk line is arranged in the rope body, can improve the softness of pull rope and tensile strength, can quickly recover to the initial state after bending, and the core strip does not deform, thereby prolonging the service life of pull rope, and it is more convenient to use.

[0014] Figure 1 It is the cross section structure schematic diagram of one embodiment of the pull rope of the utility model.
[0015] The reference numerals in the drawings are explained as follows:
[0016] 1, pull rope, 2, rope body, 21, installation slot, 3, core strip. DETAILED DESCRIPTION
[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by the person skilled in the art based on the embodiments in the utility model belong to the protection scope of the utility model.
[0018] The person skilled in the art should understand that in the disclosure of the utility model, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation on the utility model.
[0019] In the description of the utility model, if the word "several" or the like is described, its meaning is one or more, the meaning of more is two and above, greater than, less than, more than and the like are not included in the number, above, below, within and the like are included in the number. If the first, the second, the third are described, it is only used for distinguishing technical features for the purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.
[0020] The drawings are combined as follows: Figure 1 The embodiments of the utility model are further described in detail.
[0021] A pull rope 1, such as Figure 1As shown, it comprises a rope body 2 and a core strip 3. The inside of the rope body 2 is provided with a circular mounting groove 21 along the length direction thereof, and the core strip 3 is mounted in the mounting groove 21, and the core strip 3 is provided in a soft wire structure.
[0022] By providing the soft wire in the inside of the rope body 2, the softness and tensile strength of the pull rope 1 can be improved, and the pull rope 1 can quickly return to the initial state after bending, and the core strip 3 will not be deformed, thereby prolonging the service life of the pull rope 1 and making it more convenient to use. Moreover, the softness of the pull rope 1 is improved, which is also convenient for storage and carrying.
[0023] In some embodiments, the core strip 3 is provided in a cotton wire material, which has a simple structure, low cost, and high tensile strength. Moreover, the cotton wire material can make the core strip 3 have a higher fit with the inner side wall of the mounting groove 21, so that the stress surface is more fully filled.
[0024] In some embodiments, the thickness of the core strip 3 is set to 1800D-2200D, which can ensure the tensile strength of the pull rope 1. Specifically, the thickness of the core strip 3 can be set to 2000D. Wherein, D represents the denier (Denier), and the larger the denier, the thicker the core strip 3.
[0025] In some embodiments, the rope body 2 is provided in a plastic type or a woven layer structure, which has a simple structure, is convenient to process, and is beneficial to protect the core strip 3. The plastic outer layer can have good waterproof effect.
[0026] Wherein, the cross-sectional area of the core strip 3 is smaller than the cross-sectional area of the mounting groove 21, which reserves space for the bending and deformation of the core strip 3, so that the softness is higher and the bending and winding effect is better. Of course, the core strip 3 can also be filled in the mounting groove 21. Since the core strip 3 itself can be extruded and shrunk to adapt to the deformation space after bending, the filling fullness is higher, and the overall tensile strength is higher.
[0027] In some embodiments, the core strip 3 and the rope body 2 are integrally formed, which has high processing efficiency. Specifically, the pull rope 1 can be integrally extruded by a mechanical device, which is automatic production, improves the processing efficiency and the quality of the product.
[0028] The embodiments of the specific implementation are the preferred embodiments of the present application, not limited to the protection scope of the present application, wherein the same parts are indicated by the same reference signs. Therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
